It launched 5 foreign satellites, major being the French SPOT-7.
On June 30th, ISRO’s highly trusted rocket, the PSLV (Polar Satellite Launch Vehicle C-23) launched French Earth Observation Satellite- SPOT 7 and four other co-passenger satellites from SDSC SHAR, Sriharikota .
The five foreign satellites, on board PSLV C-23 were French Earth Observation Satellite SPOT-7 and Four co-passenger satellites from Canada, Germany and Singapore. ISRO, which has emerged as one of the fastest growing space agencies in the world, is known for its highly cost-effective and commercially viable missions.
This and its trusted PSLV rocket, are the major reasons why France trusted ISRO with the work of launching its highly complicated and important satellite, the SPOT-7.
The PSLV rocket lifted off at 9.52am and completed all four phases with textbook precision. Indian Prime Minister, Narendra Modi was also present on the ocassion to greet the scientists.
Interestingly, PM Narendra Modi also said that ISRO should move towards developing a satellite which can be used by all the SAARC nations, thus signalling his ambition of projecting India, as a regional as well as global power. In this context, he said,
You should develop a Saarc satellite. We should dedicate this satellite to our neighbourhood as India’s gift … India is rooted in our age-old ethos of ‘Vasudeva Kutumbakom’. Our space science reflects that. We should share the fruit of this with our neighbouring countries
Last year, ISRO launched Asia’s first interplanetary mission to Mars, at a budget which was a minimal of what NASA used for it’s MAVEN project. | aerospace | 1 |

“The five aircraft from airberlin enable us to clearly expand our European flight offering. We made a conscious decision to increase frequencies to established routes,” Austrian Airlines CCO Andreas Otto said in a statement.
ATW understands the five aircraft are part of a six-year wet-lease agreement.
Austrian Airlines will offer 46 extra flights each week from Vienna to Hamburg, Milan Malpensa, Paris Charles de Gaulle, Stockholm Arlanda and Zurich.
The five airberlin A320s will be operating in Austrian Airlines colors. As a result, the Austrian A320 family fleet will grow to 36 aircraft. Starting with the 2017 summer flight schedule, the Star Alliance member will operate seven Airbus A319s, 23 A320s und six A321s.
The fleet expansion as well as new routes and increased frequencies are all subject to approval by the Federal Competition Authority.

This invention relates to remote-control model airplanes. More particularly, it relates to model airplanes structured to resemble the fictitious television Starship EnterpriseŽ but with airfoil-lift structure for flying as a toy with remote control and for use as a vehicle for various full-sized human-portable and human-useable applications of some of its features and embodiments with and without remote control.
Previous structures and graphic representations of the famed fictitious Starship EnterpriseŽ have not been designed for airfoil lift but for a fictional concept of space flight. Consequently, there are no known full-sized or toy vehicles resembling the now legendary Starship EnterpriseŽ which are structured for flying in atmospheric conditions. A major objective of the designers of the EnterpriseŽ appears to have been emphasis of differences between space and atmospheric flight conditions. Consequently, all known structural and artistic renditions of any spaceship bearing any resemblance to the mythical Starship EnterpriseŽ are non-utilitarian or non-functional for achieving atmospheric flight.
A wide variety of model airplanes have been designed and produced to fly with remote control. Construction of model airplanes is so wide-spread and popular that it appears to be an outlet for creative drive. Yet no flying models of spaceships, rather than aircraft, are believed to have been designed or constructed in a manner taught by this invention.
U.S. Pat. No. Des. 260,789 and U.S. Pat. No. Des. 307,923, were both granted to A. G. Probert on Sep. 15, 1981 and on May 15, 1990 respectively for artistic design of the Starship EnterpriseŽ. Both were titled TOY SPACESHIP. Both comprised generally a circular plate section, two side pods and one bottom pod. The latter design was more streamlined, making it more durably appealing or classic because of an impression it conveys of having a more functional shape. But neither had an airfoil-lifting form on any structural component. All forms that could have been altered into lifting surfaces were counterbalanced with negative lift forms. As a result neither of the two Probert designs would provide lift from forward propulsion in an atmosphere.
Popularization of both Probert designs for advertising returns, however, have created a demand potential for a model spacecraft or toy spaceship that fills a seemingly subconscious human compulsion for something that is so realistically different from the fictitious Starship EnterpriseŽ that it can actually fly. It must fill a gap of public need for functional design created by its fictitious predecessor. It must be suggestive of the mythical model and yet so obviously different that its functional utility is readily apparent in order to merit wide public appeal.
Historically, in a similar manner to ways in which models have become realities of full-sized human-useable and human-portable machines and vehicles it is conceivable, foreseeable, anticipated and intended that features and embodiments of this invention are suitable for human transportation and use. It is not intended that this invention be limited to toys and models only.
One object of this invention, therefore, is to provide a model spaceship that can fly in the atmosphere.
Another object is to provide a model spaceship that resembles prior fictitious spaceships but which has differences of each component that provide airfoil lift.
Another object is to provide a model spaceship that has a working airfoil relationship of its major components.
Another object is to provide a model spaceship that has a relationship of flight control and attitude control of its structure and positioning of components.
Another object is to provide a model spaceship with obvious and apparent differences from prior fictitious spaceships.
Another object is to provide a model spaceship with motorized atmospheric propulsion.
Another object is to provide remote control for a model spaceship having motorized atmospheric propulsion.
Yet another object is to provide a propulsion-fan duct and thrust tube as a basic aerospace-vehicle component.
This invention accomplishes the above and other objectives with a remote-control model spaceship having a propulsion duct with tubular ducted fan to which a circular wing is attached at a top-forward position and having a pod wing positioned at each opposite top-side position. The circular wing is supported by a forward strut extended forwardly and upwardly from a top-front portion of the propulsion duct. Each pod wing is supported by a side strut extended sidewardly and upwardly from an intermediate portion of the ducted fan. The pod wings are joined by a horizontal wing that provides lift and horizontal stabilization. Contour of the circular wing, the pod wings, the side struts and the horizontal wing all provide lift. Lateral attitude control is provided by ailerons on the pod wings. An elevator flap for horizontal attitude control is positioned on an aft edge of the horizontal wing. A motor provides rotation of the ducted fan for propulsion. Remote control of the ailerons, elevator and motor are provided by conventional remote controls used for motorized model airplanes.

FIG. 13 is a front view of a standard digital proportional radio control system that is used as a remote controller.
Reference is made first to FIG. 1 of figures abbreviated for brevity on the drawings and referenced above as FIGS. 1-13. A propulsion duct 1 is provided with airfoil lift by a circular wing 2, a first pod wing 3, a second pod wing 4, a first side strut 5, a second side strut 6 and a stabilizer wing 7. The circular wing 2 is supported by a forward strut 8 to which the circular-edged wing 2 can be attached pivotally with a wing-pivot rod 9. Wing pivot rod 9 can have a wing axle 10 on which the circular wing 2 can rotate. The wing-pivot rod 9 can be pivoted by a wing-control rod 11 with a wing controller 12. The wing controller 12 can be a remote-controlled servo motor if remote control of attitude of the circular wing 2 is employed. If attitude of the circular-edged wing is desired to be fixed temporarily, an internally-threaded sleeve with oppositely-threaded ends can be screwed onto the wing-control rod 11 at one end and onto a pivotal strut end 13 of the wing-control rod 11. If attitude of the circular wing is desired to be fixed permanently, the wing controller 12 can be omitted. Pivotal attitude of the circular wing 2 is controlled by varying length of the wing-control rod 11 between pivotal attachment of the control rod 11 to the forward strut 8 and the wing pivot rod 9 by means of the wing controller 12. The wing-pivot rod 9 is attached pivotally to the forward strut 8 at wing-pivot axis 14.
Ailerons 15 on sides of pod wings 3 and 4 can be provided with aileron servo motors 16 and aileron-control linkage 17 for horizontal attitude control laterally. An elevator flap 18 can be employed to provide attitude control for climb and descent. For this embodiment, aerodynamic lift is provided with leading edges 19 of pod wings 3 and 4 that are sloped downwardly and rearwardly with an arcuate bottom edge 20. Rearward tilt of the circular wing 2 increases air-flow mass for bottom lift of the pod wings 3 and 4. A pod-wing trailing edge 21 can be contoured variously to eliminate lift as illustrated with equally-slanted top and bottom edges or to provide trailing-edge lift with a downwardly-sloped pod aft end 22 as illustrated with a broken line. Strut flaps 23 can be provided as an alternative or supplementary means for combined elevator and rudder functions as in conventional V-tail practice.
A rotational prime mover 24 rotates a ducted fan 25 inside of an intake end 26 of the propulsion duct 1. Flow straighteners 27 direct airflow axially through the propulsion duct 1 to a thrust tube 28 proximate an outlet end 29 of the propulsion duct 1. The ducted fan 25 can be mounted directly to a fan shaft 30 extended from the prime mover 24 or optionally to gear shaft, depending on the type of rotational prime mover 24 that is employed. The prime mover 24 can be mounted with engine struts 31 extended from the intake end 26 of the propulsion duct 1. Incorporated in an engine strut 31 can be a fuel line, not shown separately, to the prime mover 24. A throttle servo motor 32 can be provided for throttling fuel to the prime mover 24. For some types of prime movers 24, a tuned exhaust system 33 can be employed to direct exhaust from the prime mover 24 into the propulsion duct 1 to utilize all available mass flow and heat for propulsion. The tuned exhaust system 33 can be supported by an exhaust-system support rod 34 extended from the forward strut 8.
Wheels 35 can be suspended from the propulsion duct 1 with landing-gear struts 36. The landing-gear struts 36 can be resilient to withstand shock with minimal material weight.
Referring to FIG. 2, a battery 37 or other power source for operating servo motors and control means is positional in the pod wings 3 and 4 or in other suitable locations.
Referring to FIGS. 1-5, the circular wing 2 can be provided with a wing dome 38 that is relatively low in proportion to overall size of the circular wing 2. In FIGS. 1 and 2, an upwardly-slanted outside edge 39 of the circular wing 2 directs airflow in a vacuum-forming laminar pattern to an aft edge of the dome 38 to provide a double-vacuum lift adjacent to the edge 39 and adjacent to the dome 38. In FIG. 4, a relatively-high proportion of airflow is directed downwardly for bottom lift by a downwardly-slanted outside edge 40 of the circular wing 2. In FIG. 5, a proportionally-slanted leading edge 41 directs approximately three-fourths of the airflow upwardly and the remaining one-fourth downwardly in proportions approximating leading-edge contours of typical aircraft wings. With these alternative structures of the circular wing 2, lift can be achieved in accordance with desired design objectives. With either of these wing structures also, the circular wing 2 can be either freely-rotatable on wing axle 10 or fixed, depending on design objectives.
Referring further to FIG. 3, the thrust tube 28 can be pivotal laterally on thrust-tube pivot means 42. Lateral pivot of the thrust tube 28 provides steering without a rudder or vertical stabilizer. Additional steering can be provided optionally by a rudder or by V-wing flaps such as optional strut flaps 23 on struts 5 and 6.
Referring to FIGS. 6 and 7, delta-wing extensions of various proportions and forms 43 can be provided to form a delta-wing 44. The delta wing 44 is a fixed form of the circular wing 2. Contour of the delta wing 44 can be similar to standard laminar-flow wing design and one or more wing flaps 45 can be provided at a wing trailing edge 46. Due to forward positioning of the delta wing 44, the wing flaps 45 can provide both elevation and lateral control. A wing leading edge 47 of the delta wing 44 is contoured preferably with a proportionally-slanted leading edge 41 as described in relation to FIG. 5.
Referring to FIGS. 8 and 9, a laminar-lift pod wing 48 can be provided with a proportionally-slanted leading edge 49, a laminar-flow top surface 50, a flat bottom surface 51 and an aileron flap 52 at an aft end. This contour can be employed to maximize airfoil lift of the wing pod 48. A battery 37 or other power pack can be positioned within a section approximating maximum thickness.
Referring to FIGS. 10 and 11, a propulsion duct 1 can be provided with a thrust tube 28 having straight thrust-tube walls 53 as in FIG. 10 or venturi thrust-tube walls 54 as in FIG. 11. Venturi thrust-tube walls 54 allow greater increase in velocity of mass flow aft of an optionally inward-tapered section 55 of the propulsion tube 1. Venturi thrust-tube walls 54 are particularly advantageous when a reaction-propulsion prime mover 56 is employed in the propulsion tube 1. The reaction-propulsion prime mover 56 can be employed independently of, in addition to or as part of a rotational prime mover 24. The reaction-propulsion prime mover 56 can be either air-breathing, liquid-rocket, solid-rocket or a convertible engine. A fuel-storage area 57 can be provided in walls of the propulsion duct 1. Pivotal power for the thrust tube 28 can be provided by motor means such as a thrust-tube servo motor 58 positioned proximate the thrust-tube pivot means 42.
Referring to FIG. 12, a delta-wing embodiment 59 can have a vertically-stabilizing forward strut 66 to which a fixed delta wing 44 is attached. The delta wing 44 can have a wide variety of forms and proportions. An elevator flap 18 on a stabilizer wing 7 can be actuated by a power means such as a stabilizer servo motor 60 having linkage 61 in communication with the elevator flap 18.
Referring to FIGS. 1-13, a model-airplane four-channel digital proportional radio control system can be employed as a controller 65. Lateral-control flaps such as ailerons 15 and aileron flaps 52 can be operated with lateral movement of the right control stick 63. Elevation-control flaps such as elevator flaps 18 can be operated with vertical movement of the right control stick 63. Throttle can be controlled through throttle servo motor 32 with vertical movement of left control stick 62. The thrust tube 28 can be pivoted for a steering effect with lateral movement of right control stick 63. When strut flaps 23 are employed, they are operated with the same control movement as for the thrust tube 28. Thus, the strut flaps 23 and the thrust tube can be employed simultaneously. When the circular-edged wing 2 is made pivotal on wing pivot axis 14 or when wing flaps 45 are employed, either can be made to operate in opposite motion to elevator flaps 18 for control of elevating attitude, such that up to seven servo systems can be operated with four radio-wave channels. The wing flaps 45 can be employed alternatively as ailerons in place of or in conjunction with aileron flaps 52.
Control sticks 62 and 63 can be wired to control different servo motors and control elements as may be desired for particular use-conditions by particular individuals. Either control arrangement can be employed for operation of a model or for a full-sized unit. Thus, a wide selection of controls and control combinations are available.
Radio waves are transmitted through antenna 64 to respective servo motors 12, 16, 32, 58 and 60. Additional and alternative servo motors can be provided for the variety of control features made possible.
A new and useful model spaceship having been described, all such modifications, adaptations, substitutions of equivalents, combinations of components, applications and forms thereof as described by the following claims are included in this invention.

by Jeanette CainMore articles in Telescopes
Lyman Spitzer was the astronomer who first proposed the idea of an extraterrestrial observation post. NASA began building the Hubble in 1977, launching in 1990, but soon discovered that Hubble's main mirror was slightly off in shape. Computers came to the rescue by compensating for this fault. A massive black hole in galaxy M87 was discovery by Hubble in 1992, and, in 1993, Hubble's vision problem was corrected by a service mission.
The impact on Jupiter by the Shoemaker-Levy 9's impact was witnessed and recorded by Hubble in 1994. The birth of the Eagle Nebular was photographed in 1995, and provided scientists with a view of galaxies up to 10 billion light-years away. In 1997, Hubble had an infrared camera installed, monitored Mars dust storms, and checked landing areas for the Mars Pathfinder. The most powerful explosion ever witnessed was detected by Hubble in 1999. The detection revealed a galaxy having an energetic gamma-ray burster.
Launched in 1990, after decades of planning by scientists, astronomers, and physicists, the Hubble Space Telescope was launched into orbit above the hazy atmosphere of Earth. The Hubble is run by remote control by astronomers from many countries, but rather than human observations on the eyepiece, Hubble has sensitive light detectors and electronic cameras.
Hubble's heart is a reflecting telescope, but in space, it operates without an outside source of electricity, swivel mounting, and linking cables. Hubble was designed to carry equipment found on satellites, like solar panels for power, reaction wheels for direction, and radio antennas for communication with Earth-bound scientists.
NASA's Goddard Space Flight Center, Maryland, is mission control, which means that all signals, to or from Hubble, go through this center. NASA's engineers keep a continual monitoring of Hubble's equipment, and also act as a go-between the telescope and the Hubble astronomers. These astronomers are located at the Space Telescope Science Institute in Baltimore, Maryland.
Space Shuttle Discovery astronauts, Mark Lee and Steven Smith, serviced Hubble. Since the telescope needs regular servicing, as a car, the shuttle astronauts will replace equipment, including tape recorders, and computers. The Hubble can be updated by installing new cameras and light and infrared radiation detectors. In 1993's first servicing mission, Hubble's vision was corrected by installing contact lenses to correct the problem.
Hubble is an asset for studying the galaxies and stars. Earth-bound telescopes need to look upward through an atmosphere of turbulence, which continually distorts and changes the light coming from these distant places. It is similar to looking at an object through dirty water, and it is the reason that stars seem to twinkle. The Hubble has a clear view of all things in the universe, even quasars billions of light-years away.

Radar devices have been working in the same way for decades: The radar emits electromagnetic waves. Objects such as airplanes reflect these waves as echoes, which in turn are detected by the radar. This allows the position and direction of an aircraft, for example, to be precisely determined. At airports, during major events or at political summits requiring high security, radar technology is the central instrument for controlling traffic and monitoring airspace.
It's possible without radar waves
The passive radar newly developed by Hensoldt under the name TwInvis fundamentally changes the way radar works. Instead of emitting its own signals, it uses the signal echoes of existing third-party transmitters. These can be radio or television transmitters whose waves are also reflected by aircraft. TwInvis detects these reflected signals and locates the aircraft accordingly. In the process, the passive radar processes signal echoes that are billions of times weaker than the original signals. A single TwInvis unit can thus monitor up to 200 aircraft in 3D within a radius of 250 kilometers.
Many possibilities for use
The new passive radar is significantly smaller than previous radar systems and can be easily integrated into an off-road vehicle or a van. Since it does not emit its own signals, it can also be used in urban areas – unlike active radars. And it can also be used more quickly, because there is no need for coordination with the authorities. TwInvis is therefore perfect for monitoring major events such as football matches or critical infrastructures – even at short notice.
Passive radar can also be used at airports to supplement the sensors used in air traffic control, for example as a backup. TwInvis can be used as a new instrument for monitoring the airspace at small and medium-sized airports that are not yet equipped with primary radar. And it also provides support in areas with severe restrictions, such as areas where mountain slopes or other obstacles impede normal radar waves.
However, TwInvis also opens up new possibilities in the military sector. In areas with a low transmitter density, for example, several separately placed devices can work together. Since the lack of its own radar waves makes the radar practically invisible, it can neither be detected nor jammed by the enemy.
World-leading technology made in Germany
The technology underlying TwInvis has been researched worldwide for more than 15 years. Hensoldt has now achieved a breakthrough with TwInvis. A passive radar demonstrator was presented to the public for the first time at the ILA Berlin in April 2018 and shown in operation. The company has invested several million euros of its own funds in its development and carried out studies in cooperation with the Federal Ministry for Economic Affairs and Energy, among others. This innovation is further impressive proof of the global breakthroughs that aviation research in Germany can achieve. | aerospace | 1 |

You might call them Micetronauts 2.0.
The first group of star-trekking mice to ever travel to the International Space Station has returned to their home at a UCLA lab, where they’re being studied for a promising new therapy to regrow lost bone density.
“All the rodents from ISS made it back alive and healthy on July 4!,” said Dr. Chia Soo, a lead researcher on UCLA’s NELL-1 study.
A group of forty mice blasted into low-Earth orbit 220 miles up on June 3 from Florida, as part of a robust NASA science mission. Other projects on board included an investigation into mysterious pulsar stars believe to hold keys for better navigation and time-keeping capabilities on Earth, and a fruit-fly study into treating weakened cardiac muscles.
Half the mice in the NELL-1 study are still living on the Space Station and being treated with the protein that Soo and her team believe may spur degraded bone to regrow.
The other half splashed down inside a SpaceX Dragon spacecraft in the Pacific Ocean off Baja California on Monday, and were unloaded the following morning in San Pedro.
‘Looked really good’
The mice passed through the Earth’s 3,000-degree Fahrenheit atmosphere, at a rate of force equal to about five times their body weight, without injury, scientists said.
“They looked really good. They were very healthy,” said Louis Stodieck, director of BioServe Space Technologies at the University of Colorado Boulder’s aerospace-engineering sciences division.
When the 20 still-orbiting astro-mice return to join those now back in the lab, their bone development will be compared.
Stodieck, who managed the rodents’ complex travel and care accommodations, joined UCLA researchers as the first to greet the returning rodents. During their travel, they lived inside a special habitat and ate moist, nutrient-rich food bars developed by NASA. (“Think of a power bar but not quite so sweet,” said Stodieck. “The mice love it. It’s very good, I’ve actually tried it.”).
Like returning astronauts, the micetronauts appeared initially unsteady in gravity. Their space habitat had mesh walls, allowing them to crawl around with stability.
“They get so adapted to microgravity, that gravity probably feels a little hard,” Stodieck said. “They looked a little bit tenuous, but they’re getting used to it.”
Since the Soviet Sputnik program returned the first animals — dogs, rodents and insects — from a brief trip around the Earth in 1957, the U.S. Space Shuttle program has gone on to return animals from rocket trips.
But these are the first U.S. rodents to participate in a lengthy microgravity research trip, and to board the space station’s National Laboratory, Stodieck said.
“These studies, with animal models, are few and far between. They are difficult and expensive,” he said. “It’s very important for us, in any of these studies, to maximize their scientific utility. The space station is a tremendous laboratory platform. We’re learning a lot of things.”
Increasingly, researchers are studying the effects of microgravity on stem cells to understand the full potential of space research.
But the mice are promising some exciting results that could help many people on Earth, according to the scientists.
Astronauts (and micetronauts) experience severe bone loss when they travel outside Earth’s gravity-laden atmosphere. Floating around in microgravity not only depletes bone mass, it also weakens muscles — most notably, heart muscle.
“If it can work for microgravity-related bone loss, then it could have increased use for patients one day on Earth who have bone loss from trauma or aging,” Soo said.
Robust rocket recycling
SpaceX’s reusable rockets and spacecraft are enabling U.S. researchers to send experiments to orbit affordably from America for the first time in years.
Five years ago, the self-propelling Dragon became the first commercial spacecraft to dock at the International Space Station. It’s able to return to Earth by plopping, Space Shuttle-style, into the ocean.
It’s also built to return to space repeatedly throughout its life.
The Dragon craft that returned the 20 mice to Earth on July 3 previously flew to the Space Station in 2014.
SpaceX’s business model relies on such high-tech recycling — and on a consistent, persistent launch calendar.
Keeping pace with growing customer demand, SpaceX launched its third rocket in 12 days last Wednesday — just 48 hours after two successive dramatic last-second aborts on the launch pad.
Fruit flies and lemon-mint plants
The mission also carried hundreds of fruit flies for an investigation into the effects of microgravity on the cardiovascular system.
“Fruit fly hearts have similar components to humans and are much closer to humans, in some respect, than mice and rats,” said Karen Ocorr, who is leading the study at Sanford Burnham Prebys Medical Discovery Institute in La Jolla.
The research team sent hundreds of flies packed in six tissue box-sized habitats. Four of the boxes carried 2,000 fly eggs, and others carried hundreds of breeding adults, intended to give birth in space to flies that would return to Earth.
“We have a team of 12 people who will be present in the lab when we receive the flies back,” Ocorr said. “We’ll spend the next month or more trying to understand the effects on their skeletal muscle and heart muscle function, among other things.
“People who have long-term illnesses, or are infirm and spend a long time in bed, experience progressive cardiac dysfunctions,” she said, adding that this study could help develop new therapies for weak hearts.
Lennox Middle School students will also soon get back research from inside this Dragon. They’re studying whether lemon-mint plants grow better, worse, or the same in microgravity, as part of the Student Spaceflight Experiments Program.
“We wanted to use mint because it’s something we use a lot in our Hispanic culture,” said Nayeli Salgado, one of the Lennox school team members. “It has many uses — stomach aches, ear aches. You can use it instead of medicine. It takes the pain away.” | aerospace | 1 |

The company was founded in 2020 by Ayjay Lasater, Topher Haddad, and Winston Tri.
Albedo 10 cm imagery is a new type of satellite imagery that offers unprecedented detail and clarity. With a resolution of 10 centimeters per pixel, Albedo imagery can see objects on the ground that are just 10 centimeters apart. This is significantly higher resolution than any other commercial satellite imagery currently available, which typically has a resolution of 30 centimeters or more.
Albedo imagery has a wide range of potential applications, including:
Urban planning and development: Albedo imagery can be used to track changes in urban areas, such as new construction, changes in land use, and the growth of vegetation. This information can be used to inform urban planning decisions and to monitor the impact of development on the environment.
Agriculture: Albedo imagery can be used to monitor crop health, track crop yields, and identify areas of potential crop damage. This information can be used to improve agricultural practices and to ensure food security.
Forestry: Albedo imagery can be used to track forest health, monitor forest fires, and measure the effects of climate change on forests. This information can be used to manage forests sustainably and to protect them from damage.
Security and surveillance: Albedo imagery can be used to monitor critical infrastructure, track illegal activities, and identify potential security threats. This information can be used to improve security and to protect people and property.
Albedo imagery is still in the early stages of development, but it has the potential to revolutionize the way we see and understand the world around us. With its unprecedented detail and clarity, Albedo imagery can provide insights that were previously impossible to obtain.
Here are some additional benefits of Albedo 10 cm imagery:
High accuracy: Albedo imagery is highly accurate, with a ground sampling distance (GSD) of 10 centimeters. This means that objects on the ground that are just 10 centimeters apart can be distinguished from each other.
Wide field of view: Albedo satellites have a wide field of view, which means that they can capture a large area of ground in a single image. This makes it possible to track changes over time and to identify patterns that would be difficult to see with lower-resolution imagery.
High revisit rate: Albedo satellites have a high revisit rate, which means that they can image the same area of ground multiple times in a short period of time. This makes it possible to track changes that occur quickly, such as the growth of vegetation or the spread of a forest fire.
Albedo 10 cm imagery is a powerful tool that can be used to improve our understanding of the world around us. It has the potential to revolutionize a wide range of industries, from urban planning to agriculture to security. As Albedo satellites continue to launch, we can expect to see even more innovative applications for this cutting-edge technology.

Intermediate-Range ballistic missile is a noun.
A noun is a type of word the meaning of which determines reality. Nouns provide the names for all things: people, objects, sensations, feelings, etc.
WHAT DOES INTERMEDIATE-RANGE BALLISTIC MISSILE MEAN IN ENGLISH?
Intermediate-range ballistic missile
An intermediate-range ballistic missile is a ballistic missile with a range of 3,000–5,500 km, between a medium-range ballistic missile and an intercontinental ballistic missile. Classifying ballistic missiles by range is done mostly for convenience, in principle there is very little difference between a low-performance ICBM and a high-performance IRBM. The range definition used here is used within the U.S. Missile Defense Agency. Some other sources include an additional category, the long-range ballistic missile, to describe missiles with a range between IRBMs and true ICBMs. The more modern term theater ballistic missile encompasses IRBMs, MRBMs and SRBMs, including any ballistic missile with a range under 3,500 km. IRBMs are currently operated by India, Israel, and Saudi Arabia. Some other countries, such as Iran and North Korea, are said to be developing them. The United States, USSR, People's Republic of China, United Kingdom, and France were former operators.

Work on the glider, received the index of A-40 (or CT - wings of the tank), began in the most difficult period of the war - in December 1941 for the tests was provided by a serial light tank T-60.
Calculations showed that the undercarriage of the tank has sufficient strength and cushioning for the takeoff and landing. According to the concept design glider should be extremely simple and cheap in production design from nedefitsitnyh materials. Therefore adopted a long-known and well-proven scheme braced biplane with a wingspan of about 18 m. The two-spar wings, plywood with a sock to the first spar and fabric covering. Upper and lower wings connected by a system of four "I"-shaped struts and braces. Wings are equipped with slotted flaps, omitted in the landing 45 degrees down, which greatly reduces the landing speed. Office of the ailerons and flaps - cable runs on the lower wing and ailerons and flaps of the upper wing were associated with lower uprights streamlined section. On two box girder was attached dvuhkilevoe vertical tail, horizontal tail between them, too type biplanovogo system braces for rigidity. The elevator is only on the upper horizontal tail. Control surfaces are equipped with unguided trim and aerodynamic load compensators. Biplanovaya box of wings and tail boom were attached to the hull of the four points of the lower wing. Turning the handle, located on the right of the tank driver, who is also a pilot, fixed raskontrivalos and glider reset. Towing lock placed on the tank. To reduce the air resistance in flight tower for mounting a glider on a tank cannon ago unfolded. To improve visibility to the pilot-driver made a special optical device. Maximum estimated flight weight was 7.3 tons, the glider had 2 tons
Airframe manufactured in April 1942 in Tyumen, which was evacuated in size. Test A-40 began near Moscow in the Summer Research Institute (FRI) August 7, 1942 with jogging lightweight tank on a dirt airstrip and Betonka. In this objective was to find out whether the suspension will stand part of the machine speed 110-115 km / h (T-60 was 45 km / h). Were then made three reaching is "CT" to a height of 4 meters, which tested the control system.
First flight of "KT" was held on 2 September 1942, aircraft-towing-TB-3 with four reinforced (to 970 hp..) Engines AM-34RN commanded Paul Arsentievich Eremeev, formerly designer of aerobatic gliders. Glider ran a test pilot experimental test site of the airborne troops of the Red Army Sergey Anokhin. Due to the large mass and low circularity "KT" was conducted on the roadside close to the maximum engine power of the TB-3 with a speed of 130 km / h. Despite this, the rate of rise aeropoezda proved insufficient. The plane barely reached the height of 40 m.
Do not give a positive result of an attempt to increase the speed to 140 km / h, as this aeropoezd began to decline with the vertical velocity of 0,6 m / sec. In addition, the increase was the water temperature in the engine cooling system, which could lead to overheating. Under these conditions, Eremeev decided to withdraw aeropoezd area nearby airfield Bykov and unhook the glider. Anokhin, thanks to his professional skill, was able to successfully make a landing. After landing, he started the engine of the tank and not dropping wings, slowly moved toward the command post terminal. Without being warned about an unusual emergency landing apparatus, the head of airport operations on combat alert raised the calculation of anti-aircraft batteries. When a test pilot climbed out of the car, detained him, Red. The incident was settled with the arrival of rescue teams FRI. Tank under its own power delivered to the village of Stakhanov (now the city of Zhukovsky) to the airfield FRI. Thus ended the first and last flight of a flying tank.
In the act of testing a glider pilot pointed out the need to increase the trim of the elevator, setting steering control with worm gear and make constructive changes in the aerodynamic compensation to the aileron and flap control. It was noted that the task of creating a flying tank solved, but mistakes are made. Model glider and a tank for purging in the wind tunnel was performed in a simplified form (without cables connecting the biplane wing box and empennage, and without the simulation tracks the tank), which led to an error in the calculation of the aerodynamic properties of "quantum dots" and required power engine aircraft towing . Neuchteno air resistance, that does not allow the engine TB-3 to raise the glider at the desired height and complicate the management of in-flight.
Of the more powerful aircraft, capable of raising the air glider, "CT", armed at the time was a strategic bomber Pe-8 designs VM Petlyakova. However, during the war, built a total of 80 such machines. Pe-8 was used for in-depth air raids, in particular for the bombing of Berlin, and rely on its use as towing a glider "KT" was unreal.

After Ann's plane was forced to make an emergency landing last week, Romney spoke to the Los Angeles Times about how worried he had been for her safety.
"I appreciate the fact that she is on the ground, safe and sound. And I don't think she knows just how worried some of us were," Romney told the paper.
"When you have a fire in an aircraft, there's no place to go, exactly... and you can't find any oxygen from outside the aircraft to get in the aircraft, because the windows don't open. I don't know why they don't do that. It's a real problem. So it's very dangerous."
In case you're wondering, plane windows don't open because there isn't enough oxygen at cruising altitude to keep passengers alive. (The fear of window or cabin failures, which would lead to potentially fatal hypoxia, is why many planes are equipped with emergency oxygen masks).
Romney's implication that additional oxygen in the cabin during the electrical malfunction could've alleviated the problem is also misguided. In fact, if there were an electrical fire on board, additional oxygen would have fed the flames.

A probe from the spacecraft Rosetta is to land on a comet some 500 million kilometers away. The mission could teach us about life on Earth.
Achim Zschaege’s hands are calm as he steers the spaceship through the vast expanse that no human has ever seen before. “We are currently somewhere between Mars and Jupiter,” he says.
A physical engineer by training, Zschaege isn’t, of course, sitting on board the spacecraft himself. His work station is in an open-plan office not far from the central train station in Darmstadt. It is from this sparsely decorated space that he controls the unmanned space probe Rosetta.
On this night, Zschaege is the “Spacecraft Controller” (Spacon) on duty at the European Space Operations Center. Dressed casually in jeans and a sweater, his eight-hour shift has just gotten underway. He regularly checks the columns of numbers streaming across his computer screen, helping ensure that the probe stays on course. | aerospace | 1 |

WESTWOOD, N.J. – Authorities say a man hurled wet toilet paper on a New Jersey high school from a single-engine plane.
Federal Aviation Administration spokesman Jim Peters says the pilot flew over Westwood High School and its athletic fields around 6 p.m. Wednesday night.
Peters told The Record newspaper that children were on the field as the pilot dropped his soggy cargo, littering the area. There were no reports of injuries.
Peters says the Cessna 172S made three passes before landing at an airport in nearby Caldwell. The pilot, whose name was not released, was briefly taken into custody.
Peters says the man may face federal charges of reckless operation of an aircraft and dropping objects from a plane without authorization.

HCM CITY (VNS) — Former NASA Astronaut Jim Reilly gave an inspiring speech yesterday to Vietnamese youth at the American Centre in HCM City about space travel.
Reilly, 60, who had a long career at NASA, where he logged 850 hours in space in five spacewalks on three Space Shuttle missions, said his experiences in space were like a miracle.
"You can fly like a super hero in space. There are so many wonderful things about being in space," he said.
During the exchange, he encouraged local young people not to give up chasing their dreams and later talked to students who want to be astronauts.
Reilly told the local press that he wanted Viet Nam to be involved in space programmes like other countries in the world.
Before his NASA experience, he spent 17 years in the petroleum sector as a manager and exploration geologist in Dallas, Texas.
Selected by NASA in December 1994 when he was 40, the veteran space shuttle astronaut reported to the Johnson Space Center in March 1995 and completed a year of training and evaluation. He is qualified for flight assignments as a mission specialist. — VNS | aerospace | 1 |

The US major is retrofitting a total 91 of its 300-strong MD-80 fleet that do not have low-drag tail cones. Manufactured at the carrier's Tulsa maintenance base, the new tail cones consist of numerous layers of Kevlar.
Employees at Tulsa suggested that American manufacture the tail cones itself, rather than purchasing them from Boeing. "While Boeing was charging about $270,000 per tail cone, American employees found they could construct the same part for around $35,000 per tail cone," says the carrier.
American expects the retrofit will increase its fuel-conservation efforts by more than 3.8 million litres (1 million USgal) a year. Additionally, the airline says it will reduce carbon dioxide emissions by more than 9 million kg (20 million lb).
The retrofits comprise part of American's Fuel Smart initiative, which also calls for the carrier to add winglets to its aircraft. Winglet installations on all of its Boeing 737s are complete, while the 757s will be complete by the end of 2008.
American is also the launch customer of Aviation Partners Boeing's 767-300ER winglet. Under a pact reached in April, American will remove one of its 767-300ERs from service and lease it to the manufacturer for an eight-month flight-test certification programme, which is scheduled to begin in January 2008. | aerospace | 1 |

Your trip to Tunisia, certainly, accompanied bysplashing in the waters of the Mediterranean holiday in a modern hotel complex, test yourself on the miraculous properties of thalassotherapy, horse and boat-rides, jeep safari and scuba diving. But the holiday is over and it is time to return home.
How to fly from Tunis to Moscow on a direct flight?
Direct Flights Tunis Moscow irregular, buttourist season without any problems, you can fly in the desired direction without making direct. On average, a flight from Tunis to Moscow (the distance between the cities is about 3000 km) takes 4 hours.
If you are interested in price, the tickets can be purchased for around 17,000 rubles (small price increase is typical for October-December, and lowering - for February, April and May).
Tunisia Flight to Moscow with change
If your plan is to get to the desired destination with a change, you should be prepared for the fact that the flight can take anywhere from 8 to 15 hours.
For example, if you do change atMunich (the aid will "Lufthansa"), the duration of your flight by 8.5 hours when in Rome (you fly with "Alitalia") and Istanbul (the aid will come "Turkish Airlines") - 6-7 hours, and if you will fly via Paris, you can take your flight 15 hours.
Although rare, but in this direction canperformed two transplants, then the road to the house can take a whole day. Tip: since the indirect flights last for 2 or even 3 times longer than regular, it is not necessary to spend hours at the airport - this time you can devote a short walk through the transit country.
From Tunisia to Moscow will help you getThe following airlines (available passenger aircraft such as the AirbusA 320, Boeing 737-300, Fokker 100, AvroJ 100, Boeing 737-700 and others): "Tunisair" (in the high season is provided 3 times a week, and in winter - 1 flight in Week); "Nouvelair"; "Karthago Airlines"; "Aeroflot", "Transaero", and others.
Departure from Tunisia to Moscow is carried outairport "Tunis Carthage International Airport" (to get there from the city center by taxi in about 10 Tunisian dinars). Its infrastructure is well-developed, so you can comfortably spend time before the flight back home (do not forget to look at the local duty-free).
What to do in an airplane?
In the plane on a flight to Tunisia to Moscow, you can entertainyourself reading a book or crossword puzzles, and to think, to whom you give the Tunisian souvenirs in the form of jewelery, Berber rugs with interesting ornaments, leather goods, silk and blown glass. | aerospace | 1 |

Evans was selected as an astronaut by NASA as part of Astronaut Group 5 in 1966 and made his first and only flight into space as Command Module Pilot aboard Apollo 17 in 1972, the last manned mission to the Moon to date, with Commander Eugene Cernan and Lunar Module Pilot Harrison Schmitt. During the flight, he orbited the Moon as his two crewmates descended to the surface. Consequently, he is the last person to orbit the Moon alone and holds the record for the most time spent in lunar orbit at 148 hours. In 1975 Evans served as backup Command Module Pilot for the Apollo-Soyuz Test Project mission.
Apollo 17 was the final mission of the Apollo program. The craft was crewed by Commander Eugene Cernan, Lunar Module Pilot Harrison Schmitt & Command Module Pilot Ronald Evans. The mission lasted for 12 days, 13 hours, 51 minutes and 59 seconds during which time Cernan & Schmitt spent 3 days on lunar surface completing three moonwalks to collect lunar samples and install scientific instruments on the surface. Apollo 17 was the last time human beings have gone beyond Low Earth Orbit.Lunar Orbit

The airline’s routes between Perth and London, and Dallas and Sydney clock in at over 17 hours, and span 14,449 kilometers and 13,804 kilometers, respectively. The airline has also tested flights between London and Sydney, and New York and Sydney that have over 18 hours of flight time.
But none of these flights compare to Qantas flight QF6017, which departed from Sydney, Australia on March 24, 2020 for Dresden, Germany. This flight, operated by a Qantas A380, clocked an astounding 19 hours and 15 minutes of flight time across over 16,000 kilometers!
Qantas QF6017, which was flown by VH-OQA, broke the airline’s own record for the world’s longest A380 flight. The previous record-holding flight flew on the same route in the opposite direction (Dresden to Sydney) on December 19, 2019, and clocked 18 hours and 26 minutes of flight time. Headwinds moving from west to east likely contributed to the longer flight time of QF6017.
The route between Sydney and Dresden isn’t on Qantas’ schedule, and neither flight held any passengers. Dresden Airport is an Airbus maintenance hub, and it’s likely that Qantas decided to send VH-OQA in for maintenance as it grounded most of its long haul fleet.
The future of Qantas’ A380 remains unclear. The airline announced plans to ground its A380 fleet for at least three years, and frankly it’s uncertain if we’ll see the Flying Kangaroo on an A380 commercial flight ever again. | aerospace | 1 |

- Passengers and Crew Heard a Loud Bang 45 Minutes into the Flight
According to a flight safety analyst, a plane that flew for 14 hours with a large hole in its side is a “one in a million case”.
Passengers and crew reported hearing a loud bang 45 minutes into the flight, per The Courier Mail. One of the 22 tires on an Airbus A380 burst shortly after takeoff, causing a hole, the airline reports. The damage occurred to part of the plane’s aerodynamic fairing – the outer panel or ‘skin’ of the aircraft, according to EuroNews Travel.
Emirates stated: “At no point did it have any impact on the fuselage, frame or structure of the aircraft. The aircraft landed safely in Brisbane and all passengers disembarked as scheduled.” | aerospace | 1 |

At least as far as Israel Aerospace Industries (IAI) knows, the Taxibot Dispatch Towing system is the world’s first tugboat-like way to tow both wide and narrow body commercial airplanes to taxi to and from the gate and the runway without the use of their jet engines.
Consider that a Boeing 747 can burn through a ton of jet fuel for every 17 minutes it’s taxiing: I spoke with the project leader at IAI, and I learned how the TaxiBot can save billions of dollars of runway fuel, and greenhouses gases.
Instead of running the engine as the plane taxis to the runway — and if you’ve ever been stuck sitting in a plane on the runway for three hours, you know the problem all too well — jets outfitted with Taxibot won’t have to turn on the engine until minutes before takeoff.
Developed and tested in a joint venture with Airbus, the environmentally friendly semi-robotic towing system could potentially reduce annual fuel costs from $8 billion to less than $2 billion, carbon dioxide emissions from 18 billion tons to less than two million tons per year and noise emissions by a significant margin.
“This is an outcome of the very innovation process we are doing at IAI,” says Ran Braier, Taxibot project director and civil robotics director in the company’s Lahav Division. He notes that a team of about 26 people, mostly engineers, worked on building the Taxibot.
The business model is flexible. The Taxibot could be owned by the airline, provided as a service by the airport, or owned and operated by privately held ground-crew companies.
With an estimated cost of about $3 million each, the company aims to sell some 1,500 Taxibots by the year 2020. The return on investment for airlines buying the device directly is expected to be quite rapid — less than two years, depending on the size of the plane. | aerospace | 1 |

RALEIGH, NC (WECT) -
Imagine flying an airplane through a hurricane. Sounds like a suicide mission, doesn't it?
That's the reality for a crew of brave men and women from the National Hurricane Center and the United States Air Force nicknamed the "Hurricane Hunters."
They take to the skies during these dangerous storms to get real-time measurements and other important data that help forecasters better track their movements.
Hundreds of kids, members of the media, and the public gathered at Raleigh-Durham International Airport in May to meet these so-called hurricane hunters.
Rather than brave the stormy skies, they took to the sunny tarmac to get an up-close and personal tour of NOAA’s G-IV aircraft and a U.S. Air Force Reserve WC-130J “Hurricane Hunter” plane.
Major Devon Meister has been a part of the hurricane hunting mission for five years. She maintains she knows that she’s getting into-- despite the danger-- and equates the sensation to an experience millions on the ground are familiar with.
"It's essentially like, going through a car wash, and a roller coaster at the same time,” Meister explained. “It can be very bumpy, there's precipitation all the time, there's hail if we're flying through a thunderstorm, so it can get dicey."
This information ultimately helps to better track and predict the paths of future storms.
Inside the plane, each child took turns walking the narrow paths and navigating the tight spaces.
"That's a lot of buttons," remarked one child, touring the WC-130J cockpit. Without missing a beat, Major Meister reassured her, "They teach you how to work them [the buttons] one at a time."
The visit was a part of the 2017 NOAA Hurricane Awareness Tour, which coincides with National Hurricane Preparedness Week. | aerospace | 1 |

Air Marshal Ayaz A Khan (R)
Indian Air Force attack air craft have been deployed at Jammu, Udhampur, Avantipur in the Kashmir Valley and at Leh airfield in Laddakh, since long to subdue the Kashmiri’s and crush their struggle for democracy. In the 1999 Kargil war PAF did not confront the IAF, because President Musharraf feared escalation of the conflict into full-scale war. But the lesson of Kargil was that Pakistan needs a strong Air Force.
Going by numbers the Indian Air Force (IAF) is big. It has 1200 aircraft; 750 of which are combat aircraft. But the IAF also suffers the biggest number of air and ground accidents per year. It suffers the biggest numbers of pilot casualties annually. After the death of 200 IAF fighter pilots in MiG-21 crashes, the Mig-21 became infamous as “the flying coffin”. IAF top brass is to be blamed, because under training pilots were pushed directly from basic piston engine trainers straight into supersonic Mig-21’s for fighter training. This was too big a jump, resulting in high U/T pilot casualties.
Another 200 fighter aircraft including Mirage 2000s, Jaguars, MiG-29s, MiG-27s, MiG-25s and MiG-23s have been lost in air crashes and ground accidents. During the last two decades; the total tally of crashed aircraft being 500, and dead pilots 350, the IAF is a big peacetime loser of combat aircraft and pilots. Such losses had a telling effect on IAF’s fighting capability, the combat efficiency and morale of its combat crews. So the IAF had telling weaknesses as well.But IAF has procured 66 Su-30 MK-1 multirole fighter aircraft of advanced technology and high lethality from Moscow. The order was placed for 144 Su-30 MK-I’s by Indian Defence Minister George Fernandes on September 27, 1996. He had boasted that, “India will soon rank among big air powers”. This statement was made during the induction ceremony of the first batch of ten Su-30MKI multi-role jet fighters in No 20 Lightning Squadron at IAF’s Lohegaon Air Base. No 24 Hunting Hawks Squadron equipped with the earlier version of the Sukhoi Mk-30 fighters is also based there. Recently the IAF has deployed ten Su-30 MK-I fighters at Avantipura airfield near Srinager.
The supply of 144 Su-30MK-I’s tailor made for the IAF will greatly enhance IAF’s air combat and ground attack capability. Added to these are the 60 Mirage 2000-H fighters (of Kargil fame) equipped with advanced laser-guided bombs and BVR air-to-air missiles. The IAF will have a distinct edge in advanced air weaponry over the PAF, as and when the IAF procures all the Su-30MKIs, Mirages and new Mig-29’s on order.At the Sukhoi induction ceremony defence minister George Fernandes, pointing his finger at Pakistan, had said that, “The Sukhoi 30 MKI is aimed at silencing those nations who look at us with “buri nazar,” (evil intention).The IAF Su-30 MKI is fitted with superior electronics and avionics. It has thrust vectoring (directional control) capabilities, and is fitted with canards. With such improvements the MKI has amazing air combat maneuverability. It can take off with much higher bomb loads, and has a range of 3000 kilometers. It can go deep into China and Pakistan with a full load of conventional and nuclear weapons.
Indian Air Chief, Air Chief Marshal S. Krishnaswamy had stated at the induction ceremony that, “With its ability to engage several targets simultaneously the Sukhoi -30 MKI will redefine the very method of air combat.” In a joint exercise with the US Air Force over Occupied Kashmir, these Indian Air Force fighters proved superior to the F-15 air superiority fighters of US Air Force. Besides twin-engine power and safety the MKI is equipped with stealth technology, enabling it to evade radar detection. Indian defense analysts claim that the MKI can outclass China’s Su- 23 MKK and USAF F-22 and F-15 fighters. The elected government of Pakistan and the PAF must take full cognizance of the induction of 144 Su-30 MK-I aircraft in the IAF, and consequently the enhanced air threat from India. IAF has received 10 new Mirage 2000 H fighters from France and 37 rebuilt Jaguar strike fighters from HAL at Bangalore. But India’s Light Combat Air craft – the LCA under development since 1978 has yet to enter operational service. After 24 air tests, major modifications, the IAF remained highly critical of the LCA, but will be forced to buy up to 400 of these controversial fighters. The LCA will replace the MiG-21 as the IAF’s workhorse. The IAF fighter pilots did not trust Indian manufactured MiG-21s which earned such nicknames as “flying coffins”, “pilot killers”, “widow makers”; and are already distrustful of home made LCA fighters.
Pilot training has been a big problem. IAF pilots were forced into MiG-21 cockpits directly from basic piston engine trainers. The result was high wastage of pilots during operational training. British Hawk advanced jet trainer has now been inducted. It should have been inducted three decades back. It would have saved hundreds of precious lives.. Despite US foot dragging on the supply of F-16 fighters, and numerical disparity, the PAF has proved to be a credible deterrent against Indian air power. This was possible due to the high state of preparedness, readiness and robust morale of the force at all levels. The skillful management of operational assets, exemplary leadership and expertise has enabled the PAF to deter the enemy from any misadventure. The PAF is totally committed to the defense of Pakistan. The government however must realize that the PAF must have matching technology, and numerical balance with the adversary air force, in the entire range of weaponry.
The joint production JF-17 Thunders, procurement of JF-10 air superiority fighters from China, and additional F-16 fighters- should correct the air power imbalance to some extent. These new combat and strike aircraft are urgently needed for ground attack and close support operations against the terrorists, who hiding in the hills and mountains of Tribal Agencies are mounting deadly suicide bombings on Pakistani cities, cantonments and military posts.
The assassination of Benazir Bhutto and the deadly bombing of Marriot hotel in Islamabad, demands enhanced used of air power to root out terrorists and terrorism from Pakistan’s soil.The PAF has been engaged in anti-terrorist operations since several months. Army –air close support operations in the rugged and mountainous areas of Swat and Bajaur have been successful and the terrorists are on the run. Air operations must be sustained till terrorists feel compelled to surrender.
A new dangerous factor is Pakistan’s war against terrorists is United States violation of Pakistani air space by drones, gunship helicopters and fighter aircraft. Predator and Rapaer drones have been violating Pakistan’s air space, bombings tribal villages and killing Pakistani citizens since 2006. They have killed hundreds of Pakistani citizens including women and children. Washington is disregarding warnings by Pakistani President, Prime Minister, Army Chief and protests by Pakistani public. Pakistani blood cannot be allowed to be shed wantonly. Violation of Pakistani territorial sovereignty must be challenged. Pakistan Air Force must be prepared to shoot down American drones, gunship helicopters and engage USAF fighter aircraft attacking and bombings Pakistani tribal villages. We must not act as frightened crows, when outsiders continue to kill our elders, brothers, sisters and children. Pakistan Air Force must defend Pakistan’s air space. PAF’s tradition is that it will rise to great heights to defend Pakistan. | aerospace | 1 |

On its 42nd mission, ISRO's trusted workhorse 'PSLV-C40' carried the weather observation 'Cartosat-2' series satellite and 30 co-passengers (together weighing about 613 kg) at lift-off. The 44.4 meter tall rocket lifted off from the first launch pad of the Satish Dhawan Space Centre at Sriharikota.The co-passenger satellites comprise one micro and nano satellite each from India as well as three micro and 25 nanosatellites from six countries - Canada, Finland, France, Korea, the United Kingdom and United States of America. The total weight of all the 31 satellites carried on-board PSLV-C40 is about 1,323 kgs.
The 28 international customer satellites are being launched as part of the commercial arrangements between ISRO and its commercial arm 'Antrix Corporation Ltd'.Of the total number of satellites carried by PSLV-C40, 30 satellites will be launched into a 505 kms polar Sun Synchronous Orbit (SSO). Scientists would bring down the height by twice restarting the fourth stage of the PSLV-C40 for launch of Microsat satellite, which will be placed in a 359 kms polar SSO, ISRO said. The entire launch of satellites is expected to happen over a period of 2 hours and 21 seconds, it said. According to ISRO, the Cartosat-2 series satellite launch is a follow-on mission with the primary objective of providing high resolution scene specific spot imageries.ISRO had successfully launched Cartosat-2 Series satellite on June 22, 2016. The images sent by Cartosat-2 series satellite will be useful for cartographic applications, urban and rural applications, coastal land use and regulation, road network monitoring, water distribution, creation of land use maps and change detection to bring out geographical Land Information Systems and Geographical Information System applications.Friday's launch also marks the first launch for ISRO in 2018 following the unsuccessful mission of navigation satellite IRNSS-1H last year. On August 31, 2017 India's mission to launch its backup navigation satellite IRNSS-1H on board PSLV-C39 failed after the heat shield did not separate in the final leg of the launch sequence and as a result, the satellite IRNSS-1H got stuck in the fourth stage of the rocket. | aerospace | 1 |

This intrepid explorer named Cassini, expended the better part of thirteen several years orbiting Saturn and studying it and the planet’s several moons. Not only did Cassini find new small moons about Saturn, but it discovered geysers of h2o shooting out from a small moon named Enceladus. Cassini also discovered odd-shaped storms in Saturn’s ambiance, and substance like carbon, methane, ethane, and nitrogen in the ambiance of Saturn’s premier moon, Titan.
As time handed, the group understood the spacecraft was running lower on gasoline and made the decision its past yr in orbit about Saturn would be a doozy. They understood the craft would crash into the planet at the conclude anyway, so the group took hazards, sending Cassini swooping via the rings of Saturn, flying out by the moons and dashing again in. These grand finale orbits created for some amazing images. In honor of this outstanding mission, we are all going to crack quarantine and go to Saturn.

Wednesday, December 17, 2003
The centerpiece structure at the Yard of Bricks inside the Indianapolis Motor Speedway is named the Bombardier Pagoda. Bombardier's main business is building and selling airplanes, and the name is another in the long list of connections between flight and the world's most famous racetrack.
On this centennial day of the Wright Brothers' first flight at Kitty Hawk, N.C., it is noteworthy that although the Speedway was built for racing and the Indianapolis 500 has become the most famous automobile race in the world, the track has ties to the history of the airplane that date back to before the first "500" took place in 1911.
The first race at the Speedway was between gas-filled balloons in June 1909. In June 1910, the first airplane event at the track took place over several days in the infield, with both Orville and Wilbur Wright attending and fielding planes in the display. A map in the 1910 Speedway program shows the airplane course in the infield and hangar buildings.
On June 17, 1910, Walter Brookins reached 4,938 feet over the Speedway to set a world flight altitude record.
One of the participants in the 1910 display was Mel Marquette, who built his plane at his Indianapolis shop. The next year, Marquette was one of the drivers in the first Indianapolis 500, starting 20th and finishing 25th in a McFarlan.
Ray Harroun, who won the first "500" in his famed Marmon Wasp, also built an airplane and flew it off the Speedway grounds.
Caleb Bragg, a Yale and MIT graduate, finished 37th in the 1911 Indianapolis 500 and co-drove with runner-up finisher Teddy Tetzlaff in 1912. A Cincinnati native, Bragg not only was a pioneer driver but also became an Army test pilot during World War I. He was co-organizer of the Wright-Martin Co. in 1916, and in 1917 became the first American to exceed 20,000 feet in flight.
Bragg's flying career continued after that record. He was the governor of the Aero Club of America and member of its contest commission. He also was director of the Wright Aeronautical Corp., and later formed a company that eventually was absorbed by Bendix Aviation. Bragg became president of Langley Aviation, and his final position was vice president/engineer for C.M. Keys Aircraft Service.
The exploits of Eddie Rickenbacker are legendary in both Speedway and aviation lore. He drove in the Indianapolis 500 in 1912 and 1914-16, then learned to fly in France and became the leader of the American 94th Hat-in-the-Ring squadron flying and America's ace-of-aces with 26 German plane kills during World War I.
After the war, he bought the Speedway and ran it from 1927-45. He also ran Eastern Airlines. During World War II, he survived 21 days in a life raft after his B-17 bomber was ditched in the Pacific Ocean.
Georges Boillot was a Frenchman who was favored to win the 1914 Indianapolis 500 after capturing the 1912-13 French Grand Prix. He was the fastest qualifier for the 1914 race at 99.86 mph - nearly the first 100-mph lap at the Speedway - but placed 14th after problems with the frame of his car.
Boillot returned to his native France following that lone appearance at Indianapolis and enlisted in the army, becoming the chauffeur for French Gen. Jonfre. He took up flying as a sport and moved to the aviation corps. On May 20, 1916, he flew over Verdun and encountered five or seven (depending on reports) German pilots.
He shot down one before he was struck by a German bullet and crashed to become the only Indianapolis 500 driver to die in aerial combat.
During America's participation in World War I in 1917-18, the Speedway closed as a racetrack. But it remained open as an airfield. The 821st Aero Squadron, based on the grounds, repaired and serviced planes flying on hops across the country.
Just last month at Lake County, Ind., among items sold at an estate auction was a picture of the squadron standing in front of the Speedway hangar.
One of the early fliers in those days was Henry Boonstra, who was a pilot for the Signal Corps. He joined the Post Office Department and ferried surplus aircraft to the repair depot. He attended the Jack Dempsey-Jess Willard heavyweight fight in July 1919, carrying Mary Bostwick of The Indianapolis Star on the flight to Toledo, Ohio. He then became one of the first pilots to make a night flight as he flew her back to Indianapolis.
Boonstra circled the track until enough cars lined up with their lights on to enable him to land.
The years between the world wars saw many aviation personalities, such as Amelia Earhart, Jacqueline Cochran and Roscoe Turner, appear at the Speedway as guests or honorary officials.
When World War II began, some of the best mechanical minds of the Indianapolis 500 were chosen for key roles in the war effort. For instance, three-time Indianapolis 500 winner Wilbur Shaw headed Firestone's aviation depart. Other drivers, like Rex Mays, flew planes.
Smokey Yunick, later to become one of racing's most famous mechanics, flew on bomber raids over Europe. Ray Crawford was a P-38 fighter pilot who shot down seven planes and after the war became a jet fighter test pilot and a three-time Indianapolis 500 starter. Rodger Ward, destined to win two Indianapolis 500s, taught pilots how to fly a P-38.
Drivers Bill Cheesbourg, Mike Magill and Marshall Teague also were World War II Army Air Force veterans, and six-time Indy starter Jimmy Reece served during the Korean War.
Many drivers flew their own planes after the war.
Two-time Indy 500 starter Pete Halsmer flew helicopters during the Vietnam War.
In the 1960s, astronauts began making regular appearances at the track in May. Jim Rathmann, 1960 Indianapolis 500 winner, had a prominent car dealership near Cape Canaveral and made friends with many astronauts.
Gus Grissom, one of the original five astronauts, was from Mitchell, Ind. Grissom, fellow astronaut Gordon Cooper and Rathmann co-owned the race car Art Pollard drove during the second half of the 1965 champ-car season.
Among the astronauts who visited the Speedway were Neil Armstrong, the first man to walk on the moon, Buzz Aldrin, Cooper, Pete Conrad, Alan Shepard and Gene Cernan, the last man on the moon. John Glenn, the first American to orbit the Earth, rode in the Pace Car convertible in 1971.
In 1998, Indianapolis native David Wolf came down from 4½ months aboard the Russian space station Mir and was a star celebrity at the "500." Seven other astronauts who participated in the 16-day shuttle flight of the Columbia STS-90 also attended the race.
Just last May, legendary Indianapolis 500 team owner Roger Penske announced that NASA had become involved with his team and its telemetry.
Looking at Indianapolis 500 Pace Car drivers, Gen. Chuck Yeager, who handled the duty in 1986 and 1988, had top pilot credentials. He was a World War II flying hero who became the first pilot to break the sound barrier during post-World War II testing of jet fighters.
There undoubtedly are many others who have a connection with the Speedway and flying since the Wright Brothers first brought their cloth-winged fliers to the track in 1910.
So the Speedway can claim it has had a special niche in the first 100 years of flight.

Sperry Messenger (Replica)
In the years following World War One, the U.S.Air Service designed a number of its own airplanes and then asked the aircraft industry to bid on building them. The Messenger was designed in 1920 at McCook Field, to provide the Army with a light message carrier to replace motorcycles in serving that function and to do the job far more quickly. Powered by a novel three-cylinder 64hp Lawrance engine, built on Long Island, the Messenger was designed as a practical single-place airplane intended to be able to fly out of small unprepared fields and from country roads.
The Lawrence Sperry Aircraft Company of Farmingdale won the contract and ultimately built 42 Messengers. Lawrence Sperry, son of inventor Elmer Sperry, founded his own aviation company on Long Island in 1917. Sperry lived in Garden City and he kept the prototype Messenger for himself, using the road in front of his house as a runway. Sperry used this plane as a demonstrator and at one point landed it on the plaza in front of the Capitol in Washington. In 1922, over Mitchel Field, Lawrance Sperry, using a Messenger, made the first experiments aimed at testing the feasibility of hooking on to an airship in flight, and in 1923 he entered one in the St.Louis Air Races placing fourth. The Messenger was constructed entirely of wood, with the wings and tail fabric covered.
In December 1923, Lawrence Sperry, in a Messenger, made a forced landing in the English Channel and apparently drowned while trying to swim ashore.
This aircraft is a full-scale exact replica built by museum volunteers from original plans. Complete with an original engine based on the Lawrance, the aircraft is capable of being flown.
Length: 17' 9"
Top Speed: 97 mph.

About Geosynchronous Satellite Launch Vehicle (GSLV)
- Geosynchronous Satellite Launch Vehicle (GSLV) is an expendable launch system operated by the Indian Space Research Organisation (ISRO).
- GSLV was used in fourteen launches from 2001 to 2021, with more launches planned.
- The Geosynchronous Satellite Launch Vehicle (GSLV) project was initiated in 1990 with the objective of acquiring an Indian launch capability for geosynchronous satellites.
- GSLV uses major components that are already proven in the Polar Satellite Launch Vehicle (PSLV) launch vehicles in the form of solid rocket boosters and the liquid-fueled Vikas engine.
- Due to the thrust required for injecting the satellite in a geostationary transfer orbit (GTO) the third stage was to be powered by a LOX/LH2 Cryogenic engine – and the Indian cryogenic engine which was built for this purpose at the Liquid Propulsion Systems Centre uses liquid hydrogen (LH2) and liquid oxygen (LOX).
About GSLV launch vehicles
- GSLV Mark III is a three-stage medium-lift launch vehicle developed by the Indian Space Research Organisation (ISRO).
- GSLV MK III is designed to carry the 4-ton weight of satellites into Geosynchronous Transfer Orbit (GTO), or about 10 tons to Low Earth Orbit (LEO), which is about twice the capacity of GSLV Mk II, and more than thrice the capacity of ISRO’s old workhorse PSLV.
- The GSLV-F10 was a three-stage engine rocket, with
- the first being solid fuel and the four strap-on motors by liquid fuel;
- the second being liquid fuel engine;
- the and third being a cryogenic engine.
About Acquiring the Cryogenic Engine
ISRO, during the 1990s, planned to acquire booster technology from the Russian Space Organization, Glavkosmos. But, since the United States opposed this technology transfer and imposed sections against the ISRO in 1992, Glavkosmos halted the transfer but agreed to sell some hardware. As a result, India developed its own technology and research capability.
About GSLV and PSLV – Differences and Similarities
- GSLV (Geosynchronous Satellite Launch Vehicle) and PSLV (Polar satellite launch vehicle) both are satellite- launch vehicles (rockets) developed by ISRO.
- India joined a group of six nations on 1994, and successfully demonstrated the placement of 800- kg remote sensing satellite, IRS-P2 using PSLV.
- PSLV earned its title ‘the Workhorse of ISRO’ when it consistently delivered the IRS series of satellites.
- GSLV presented the Indian Space Program with its most demanding test. It was developed when India felt the need for a heavy lift booster, in the early 1980s (as PSLV was inadequate to place heavy payloads in geosynchronous orbit).
- PSLV is the third generation launch vehicle of India and the first Indian launch vehicle which is equipped with liquid stages. GSLV, on the other hand, is the fourth generation launch vehicle and is a three-stage vehicle with four liquid strap-ons.
- PSLV is designed mainly to deliver the earth observation or remote sensing satellites, whereas, GSLV has been designed for launching communication satellites. GSLV delivers satellites into a higher elliptical orbit, Geosynchronous Transfer Orbit (GTO) and Geosynchronous Earth Orbit (GEO).
- PSLV can carry satellites up to a total weight of 2000 kgs into space and reach up to an altitude of 600-900 km. GSLV can carry weight up to 5000 kgs and reach up to 36,000 km.
About Propellants used in our Rockets
- A propellant is a chemical mixture burned to produce thrust in rockets and consists of a fuel and an oxidizer.
- Fuel is a substance that burns when combined with oxygen-producing gas for propulsion.
- An oxidizer is an agent that releases oxygen for combination with a fuel. The ratio of oxidizer to fuel is called the mixture ratio.
- Propellants are classified according to their state – liquid, solid, or hybrid.
- Liquid Propellants: In a liquid propellant rocket, the fuel and oxidizer are stored in separate tanks and are fed through a system of pipes, valves, and turbopumps to a combustion chamber where they are combined and burned to produce thrust.
- Liquid propellants used in rockets can be classified into three types: petroleum, cryogens, and hypergolic.
- Cryogenic propellants are liquefied gases stored at very low temperatures, most frequently liquid hydrogen (LH2) as the fuel and liquid oxygen (LO2 or LOX) as the oxidizer. Hydrogen remains liquid at temperatures of -253 oC (-423 oF) and oxygen remains in a liquid state at temperatures of -183 oC (-297 oF).
- Solid propellant: These are the simplest of all rocket designs. They consist of a casing, usually steel, filled with a mixture of solid compounds (fuel and oxidizer) that burn at a rapid rate, expelling hot gases from a nozzle to produce thrust. When ignited, a solid propellant burns from the center out towards the sides of the casing.
What is a Geostationary Orbit, and what the other types of Orbits?
- A geostationary orbit, often referred to as a GEO orbit, circles the Earth above the equator from west to east at a height of 36 000 km. As it follows the Earth’s rotation, which takes 23 hours 56 minutes and 4 seconds, satellites in a GEO orbit appear to be ‘stationary’ over a fixed position. Their speed is about 3 km per second.
- As satellites in geostationary orbit continuously cover a large portion of the Earth, this makes it an ideal orbit for telecommunications or for monitoring continent-wide weather patterns and environmental conditions. It also decreases costs as ground stations do not need to track the satellite. A constellation of three equally spaced satellites can provide full coverage of the Earth, except for the polar regions.
Geostationary transfer orbit
- This is an elliptical Earth orbit used to transfer a spacecraft from a low altitude orbit or flight trajectory to geostationary orbit. The apogee is at 36,000 km. When a spacecraft reaches this point, its apogee kick motor is fired to inject it into geostationary orbit.
Low Earth orbits
- A low Earth orbit is normally at an altitude of less than 1000 km and could be as low as 160 km above the Earth. Satellites in this circular orbit travel at a speed of around 7.8 km per second. At this speed, a satellite takes approximately 90 minutes to circle the Earth.
- In general, these orbits are used for remote sensing, military purposes and for human spaceflight as they offer close proximity to the Earth’s surface for imaging and the short orbital periods allow for rapid revisits. The International Space Station is in low Earth orbit.
Medium low Earth orbit
- This orbit takes place at an altitude of around 1000 km and is particularly suited for constellations of satellites mainly used for telecommunications. A satellite in this orbit travels at approximately 7.3 km per second.
- As the name suggests, polar orbits pass over the Earth’s polar regions from north to south. The orbital track of the satellite does not have to cross the poles exactly for an orbit to be called polar, an orbit which passes within 20 to 30 degrees of the poles is still classed as a polar orbit.
- These orbits mainly take place at low altitudes of between 200 to 1000 km. Satellites in polar orbit look down on the Earth’s entire surface and can pass over the North and South Poles several times a day.
- Polar orbits are used for reconnaissance and Earth observation. If a satellite is in polar orbit at an altitude of 800 km, it will be travelling at a speed of approximately 7.5 km per second.
Sun synchronous orbits
- These are polar orbits which are synchronous with the Sun. A satellite in a sun synchronous orbit would usually be at an altitude of between 600 to 800 km. Generally, these orbits are used for Earth observation, solar study, weather forecasting and reconnaissance, as ground observation is improved if the surface is always illuminated by the Sun at the same angle when viewed from the satellite.

The boys began yesterday (Monday), today the new engine was installed around 10:30. So we are talking about 24 hours to get one engine out and the other engine in. Now the new engine does have to be rigged with the intake fairing and starter which come off the old one before it can go up there. The aircraft won't actually be ready for test flight for this engine change until late tomorrow (Wednesday). So we are talking about changing at T58 on an S61 in around two and half days with three to four guys working together, two shifts per day!? How would that compare? Any of you wrenches out there work on S61s and can comment??? What would be an expected kind of norm for commercial operations? By comparrison when we were deployed at sea, our techs (three guys) changed one of our engines twice in the same day (long story and yes we had two spares) and both were test flown, so it can be done. :up: Quote Link to comment Share on other sites More sharing options...

Representative of Air Manas airline, Daniyar Arynov, told at a round table discussion.
According to him, governments of all countries support their domestic aviation, providing various benefits.
«We would like to be supported, exempted from customs duties, taxes, fees in respect of aircraft. Such a scheme works in Uzbekistan and many countries of the Eurasian Economic Union,» Daniyar Arynov said.
Representative of the company stressed that the aviation industry has come to the extreme line, after which it would be difficult to recover it.
«The law has been signed. Therefore, it makes no sense to talk about its intricacies, we need to talk about state support of the aviation industry,» he stated.
Recall, on January 15, the President of Kyrgyzstan Sooronbai Jeenbekov signed the law on Amendments to the Air Code of Kyrgyzstan, which confirmed the country’s commitment to the Open Skies policy. | aerospace | 1 |

The US space and aviation agency NASA decided to launch its new mission to the moon, called "Bergerin", on December 24, and to land on the moon during the last week of December 2024, for the first time in nearly half a century.
The Bergeren mission was developed by the American company Astrobotec, which aimed to reduce costs so much that several years ago it was awarded a $79.5 million contract to deliver 14 NASA payloads to the moon.
The current mission carries about 10 payloads of various types, all of which have a mass of about 90 kg, and will include instruments sent by NASA to study the lunar environment, in particular the outer shell of the moon, the thermal properties of the lunar riches and the abundance of hydrogen in it, and the magnetic field of the moon.
The experiments to be conducted by the mission are followed by NASA, with the exception of one, the radiation detector, which follows German research teams, and these detectors will accurately measure the level of radiation that the human body will encounter on a journey to the moon and back.
All of these scientific missions are side steps in NASA's manned Artemis mission, which will launch over the next few years to put humans on the moon again, expected in December 2024.

If the mission succeeds in achieving its goals, Astrobotec will be the first private company to land a vehicle on the moon in history, and with the success of the mission, the United States will continue to contract with the same company to convert a number of instruments to the moon before American astronauts arrive there.
This comes in the context of NASA's shift towards private companies in developing a number of missions, and in fact this entire version will be managed by private companies, as the mission itself belongs to the Astrobotec company while the mission will be launched on board a rocket belonging to the American company SpaceX.
In recent years, a series of problems have emerged on the International Space Station, and it is clear that it will be out of work soon, and NASA has already begun its plans to build a new space station, but unlike the previous station, the private sector will contribute strongly this time.
The agency reached an agreement with Axiomspace late last year to send a module from its space station to connect it to the International Space Station as an initial experiment, and NASA also awarded contracts to develop commercial space stations worth a total of $415.6 million to Jeff Bezos' Blue Origin, among other companies.

According to media reports in recent weeks, Boeing is close to sealing a deal to ScanEagle sell unmanned aerial vehicles (UAVs) to Vietnam.
The ScanEagle systems considerably increase their intelligence collection and reconnaissance ability and developed by Insitu Inc., a wholly owned subsidiary of Boeing company. ScanEagle carries a stabilized electro-optical and/or infrared camera on a lightweight inertial stabilized turret system, and an integrated communications system having a range of over 62 miles (100 km); it has a flight endurance of over 20 hours.
VnExpress noted that the sale will be supported through U.S. Foreign Military Financing and the recipient will be the Vietnamese Coast Guard, Yeong Tae Pak, Boeing’s marketing director for defense sales in Southeast Asia, said Wednesday at the Langkawi International Maritime and Aerospace Exhibition in Malaysia.
“The sale is in progress,” British security magazine Jane’s quoted him as saying.
The number of UAVs to be bought is not known.
Yeong said the deal is as an indicator of Boeing’s defense sales strategy in newer regional markets like Vietnam, where opportunities to grow its defense presence is “being pursued through lower-tier platforms.” | aerospace | 1 |

San Marcos, Texas — The skies over San Marcos were filled with aircraft from the Civil Air Patrol on Saturday as five teams from around the state competed in the second annual Texas Wing Aircrew Competition. The three-person crew from Group 3, which encompasses Dallas, Irving and Waco, took home the trophy after a hectic day of flying, inspections and tests.
The winning team, made up of Major Scott Knightly, Captain Brian Relin and Captain Mark Holub, edged out the competition in three of the seven events and were lauded for their exemplary skills in the disaster response portion of the contest. Group 3 will represent Texas against five other states in the upcoming Southwest Region competition, also held in San Marcos, in May.
Texas Wing Group 6 (Fort Worth region) finished in second place, and Group 4 (Houston region) placed closely behind in third.
While the event provided a venue for friendly competition and the chance to earn bragging rights, the major theme is to prepare aircrews and operations staff for large scale missions.
"During last year's event we quickly realized the training opportunities being presented," said Lieutenant Colonel Shane Lipson, Texas Wing's Standardization and Evaluation Officer and the coordinator for the event. "You have multiple aircraft in the air, people running radio communications, and the logistics of keeping everything running smoothly," he said. "It's a perfect analogy to the sort of operations we run during disaster response."
The competition events included inspections, quizzes and simulated missions. Each event is meant to reinforce the professionalism with which the aircrews regularly operate while also promoting the idea that the business of saving lives requires urgency, safety and accuracy.
"We're glad we were able to host this competition again in San Marcos," said Maj. Matthew Congrove, Commander of the local squadron and one of the event judges. "We owe a large amount of thanks to our local partners including our hosts, the CENTEX Commemorative Air Force, as well as Berry Aviation and Texas Aviation Partners."
"We look forward to the Southwest Region competition in a few months and will be cheering on the home team," he added.

Aerospace and defense facts
The country has experienced multiple transactions regarding the purchase and manufacture of different defense and aerospace equipment. In 2014, Brazil manufactured a 15,000 kg aircraft via Embraer and during the same year, the Brazilian Air Force purchased Gripen aircraft from SAAB, making the country the 10th largest in military expenditure in the world.
Private and public security have been a major concern in the country.
It also the base for a major aerospace and defense cluster, the Sao Jose Dos Campos, which is also the home to Embraer, the third largest jet manufacturer in the world.
Besides Embraer, there are also other relevant aerospace and defense companies that are actively producing in the country. These are Helibras, Avibras, Odebrecht, Andrade Gutierrez, CBC, Taurus, Imbel, and Iveco. These companies are called Strategic Defense Companies (EED).
Another sector of companies called Defense Company (ED) consists of Ael Sistemas, Ares, Avio, CodeCiphers, Columbus, Data Com, Dsg Defence, Omnisys, Rockwell Collins, and Stefanini. ED’s are different from EED’s but can be considered EED’s, as long as they conform to certain standards.
Opportunities in aerospace and defense
Due to its excellent reputation as a quality aircraft provider, many top companies are involved in the manufacturing process in this sector. High quality equipment is offered to the sector at affordable prices.The suppliers of defense and aerospace equipment tend to attract much investment from large companies.
In fact, the Brazilian Armed Forces and the Ministry of Defense are expected to invest 410 BBRL until 2031 boosting the Brazilian Army, Navy and Air Force to emerge as the leading nation in large aeronautic and defence projects.
A lot of developments are still in the process for the betterment of the sector. Submarines with nuclear propulsion are being used in the country and are expected to continue until 2031. The country also continues to purchase new ships to support its equipment modernization.
More large projects are expected to be announced in the next 15 years and this will definitely open up more opportunities in the country despite short-term government acts.
Brazil is undoubtedly a highly competent country when it comes to its aerospace and defense sector. To ensure success of their ambitious projects by playing a role in this booming sector, by way of investment, one would require detailed market research. The data will assist interested foreign players to identify the opportunities and assess challenges accurately. | aerospace | 1 |

Limited number of aircraft in British skies
The United Kingdom's national air traffic control agency announced that it has limited the number of planes in circulation today in British airspace. A reasoned decision as a result of a technical problem. This choice caused delayed and canceled flights across Europe, with passengers in some cases being stranded on the airport tarmac shortly before boarding.
"We are currently experiencing a technical problem and have implemented traffic flow restrictions to maintain safety. Engineers are working to find and resolve the fault", Britain's National Air Traffic Service (Nats) said in a statement, adding that it airspace was not closed.
It has had serious repercussions especially at Irish airports. Companies like British Airways and Ryanair, as well as Manchester, London-Stansted, London-Gatwick and London-Heathrow airports said they were working closely with the UK's national air traffic control authority to reduce the impact on aerial operations.

The reason is that Earth will pass between Mars and the sun and will be closest to the red planet on July 31 — an estimated 35.8 million miles away. Mars will be notably visible to the naked eye all the way through July, but a telescope may come in handy to get a really vicarious thrill.
Oh and Perihelic Opposition occurs every two years, so it’s a relatively common event. It’s just rare for it to happen when Earth is at Aphelion and Mars is at Perihelion— luke (@lukeylux) 17 июня 2018 г.
On July 27, Mars will be in perihelic opposition. This marks the red planet's closest approach to Earth since Aug. 27, 2003 when Mars made its closest approach in 60,000 years. Currently the brightest 'star', Mars will triple in brightness leading up to July 27. Pic by Alan Dyer. pic.twitter.com/Wk7iCF3Kmq— Granny (@Grannytologist) 8 июня 2018 г.
So-called perihelic opposition accounts for the phenomenon; expressed in simpler terms, this is when Earth passes straight between the red planet and the sun. According to NASA, perihelic opposition is a rare event as occurs only once every 15 to 17 years, when Earth and Mars's orbits align to bring the two planets close together, thus pleasing sky gazers with fantastic views. | aerospace | 1 |

The operator runs six airports in the UK, including Heathrow and Stansted but all have remained out of action since air traffic control group NATS closed British air space to commercial aircraft last Thursday.
A statement from the group – owned by Spanish infrastructure company Ferrovial – said: “BAA entered this period of flight suspensions with sufficient available funds to mitigate the closure of British air space for a considerable amount of time.”
It added: “Right now, we don’t think the airports’ closure will have a material impact on our regulated airports’ abilities to finance their activities.”
Airline BA has asked for compensation from the European Union and british government for its losses – estimated at around the same rate as BAA’s – over the grounding of flights. | aerospace | 1 |

The movement of air over the curved surface of the paper (airfoil) creates a low pressure area above the "wing" and allows the higher pressure air below the paper to "lift" it. Bernoulli�s principle states that a fluid-like air exerts less pressure when it is moving quickly than when it is moving slowly. (Actually, an increase in the velocity of a fluid is always accompanied by a decrease in the pressure exerted by that fluid.) The lift created by the movement of air over a wing must be enough to support the weight of a plane and its contents for the plane to fly.
Another force acting against a plane is drag. Drag is created by the resistance of the air to the movement of a plane through the air. Usually, the sleeker the design, the less drag is created. The force used to counteract drag is thrust. Thrust is created by the motor or engine in a powered plane.

WestJet Expands European Network with New Barcelona Flight
Calgary-based WestJet launched seasonal nonstop flights to Barcelona’s El Prat Airport from its hub at Toronto on Friday, marking WestJet’s fifth transatlantic service. Joining the list of the airline’s mostly seasonal European operation, this is also the airline’s first flight to Spain and the Iberian Peninsula. The new service will be operated on its existing Boeing 767-300ER aircraft, however, and not its new Boeing 787-9 Dreamliners.
“This flight between Barcelona and Toronto complements our existing Toronto to London Gatwick service in providing our guests with another non-stop flight to a popular European tourism and financial center,” Arved von zur Muehlen, WestJet’s Chief Commercial Officer, said at the inaugural flight.
“In addition, Europeans looking to travel to Canada this summer now have even greater access to the greater WestJet network through our Toronto hub.”
The new service to Barcelona operates using WestJet’s Boeing 767-300ER widebody aircraft which features 24 Premium Class recliner seats and 238 economy class seats. Complimentary food and beverages, power outlets and WestJet Connect streaming in-flight entertainment are also included in the service.
The service operates three times weekly departing Toronto at 10:05 p.m. and arriving in Barcelona the next day at 11:50 a.m. After a quick few hours on the ground, the aircraft then leaves Barcelona at 1:20 p.m. and arrives back in Toronto at 4:15 p.m. The arrival time in Toronto offers travelers convenient flight times and one-stop flight connections to destinations both within and outside of Canada.
WestJet will operate flights to Barcelona until Oct. 21 this year. For the summer 2019 season, WestJet will operate London service from Vancouver, Edmonton, Winnipeg and Toronto, service from Halifax to Glasgow, London and Paris, and service between St. John’s and Dublin.

Airbus and STMicroelectronics agreed to research together to develop power electronics for future hybrid-powered aircraft and full-electric urban air vehicles. The joint research includes employing less power consuming switching devices made using advanced materials such as Silicon Carbide and Gallium Nitride.
Since weight and size of the systems and materials used in a aircrafts is a critical design factor, power electronics design engineers explore the benefits of wide bandgap semiconductor materials for aircraft electrification. Wide bandgap semiconductors like Silicon Carbide (SiC) and Gallium Nitride (GaN) enable the development of smaller, lighter and more efficient high-performance electronic devices and systems, particularly in applications requiring high power, high frequency, or high-temperature operations.
The joint effort to focus on developing SiC and GaN devices, packages, and modules adapted for Airbus’ aerospace applications. "The companies will assess these components by conducting advanced research and tests on demonstrators, such as e-motor control units, high and low voltage power converters, and wireless power transfer systems" said STMicro.
“This collaboration with STMicroelectronics, a global leader in power semiconductors and wide bandgap technologies, will be key to support Airbus’ electrification roadmap,” said Sabine Klauke, Airbus Chief Technical Officer. “Leveraging their expertise and experience in power electronics for automotive and industrial applications with our own record in aircraft and VTOL electrification will help us accelerate the development of the disruptive technologies required for the ZEROe roadmap and CityAirbus NextGen.”
“STMicroelectronics is the market leader at the cutting edge of the development of innovative power semiconductors with higher-efficiency products and solutions based on advanced materials, such as Silicon Carbide and Gallium Nitride. We already have a strong, transformational presence in mobility and industrial applications, reinforced by a vertically integrated global SiC supply chain, to support our customers globally with electrification and decarbonisation,” said Jerome Roux, President, Sales & Marketing, STMicroelectronics. “Aerospace is a highly demanding market with specific requirements. Cooperating with Airbus, a global leader in this industry, gives us the opportunity to define together new power technologies the industry needs to realise its decarbonisation goals.”
Aircrafts emit huge amount of carbon dioxide into the atmosphere and are major pollutants. To decrease the air pollution, Aircraft engine designers are preferring to go for hybrid engines having both gasoline propulsion engines and electric propulsion. Hybrid-electric propulsion can bring down CO2 emissions by up to 5%. In case of helicopters it is as high as 10%.
ST says "Future hybrid and full electric aircraft require megawatts of power to operate. This implies huge improvements in power electronics in terms of integration, performance, efficiency, and component size and weight."

The California-based private company's Falcon 9 rocket carrying the Dragon capsule, filled with cargo supplies, blasted off from the Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on Friday. Moments after the launch, the capsule faced trouble with its propulsion system that is required to thrust the Dragon to the space station.
The thruster issue delayed the process of docking the capsule to the station. But the problem has now been resolved, and NASA scientists announced that the capsule will be grappled on Sunday at 6:31 am EST by Expedition 34 Commander Kevin Ford and NASA Flight Engineer Tom Marshburn, aboard the station.
"The station's Mission Management Team unanimously agreed that Dragon's propulsion system is operating normally along with its other systems and ready to support the rendezvous two days after Friday's launch on a Falcon 9 rocket from the Cape Canaveral Air Force Station in Florida," NASA announced in a statement.
Once captured, the Dragon will be docked with the Earth-facing port of the Harmony module. Flight engineer Chris Hadfield of the Canadian Space Agency will use commands to bolt the capsule into place.
NASA TV will show a live coverage of the capsule being grappled at 3:30 am EST. Coverage of berthing operations will begin at 8 am.
Despite the delay in the capsule's arrival, there will be no change of plans in the capsule's return to Earth. Dragon is scheduled for a parachute-assisted splashdown in the Pacific Ocean off the coast of Baja California on 25 March.
Dragon's launch is SpaceX's second commercial resupply mission to the space station, a research laboratory orbiting 250 miles above Earth. SpaceX successfully launched its first test flight to the space station in May 2012 and sent its first supply run last October.
After the retirement of NASA's space shuttles in 2011, the space agency has signed multi-billion dollar contracts with some private companies to send cargo resupply flights to the station. NASA has made a $1.6 billion deal with SpaceX to use at least 12 of their cargo flights for space missions.
Similarly, the space agency has a $1.9 billion contract with Virginia-based private company Orbital Sciences to send eight cargo resupply flights to the space station using its Antares rocket. The first Antares rocket test flight is likely to be carried out later this year. | aerospace | 1 |

Sept. 1. PRNewswire. ROCKVILLE
A SkyLine automated air traffic management (ATM) system supplied by Lockheed Martin has gone into full operation at the Aktobe Area Control Center (ACC) and three remote towers in Kazakhstan.
The system, installed under contract with Kazaeronavigatsia, the air navigation authority for Kazakhstan, is part of a major modernization program using advanced technologies to achieve the highest standards of quality, safety and security in air traffic management for the region. The system achieved site acceptance ahead of schedule earlier this year and completed the transition in late June.
A comprehensive commercial, off-the-shelf automation system, SkyLine ATM includes flight data processing and surveillance data processing capabilities that can function as a tower, terminal area, procedural or flow monitoring system service. It provides a flexible configuration of features and functions to fit user requirements.
At Aktobe, the system provides en route and approach control at the Aktobe ACC, as well as tower control at Aktobe and the airfields at Uralsk, Atyrau, and Aktau. The contract also includes a Lockheed Martin Omnyx air sovereignty system at the Astana area control center that provides air surveillance across the country and is the foundation for an interagency coordination center in that city, which is the Kazakhstan capital.
“We have been pleased to work with Lockheed Martin on this project, which enhances the safety, capacity and reliability of our national airspace,” said Sergey Kulnazarov, the director general of Kazaeronavigatsia. “It has significantly advanced our progress toward achieving an integrated, national ATM program.”
“Thanks to the efforts of Director General Kulnazarov, Kazaeronavigatsia and the Ministry of Transport and Communications, the international community recognizes the quality and safety of air navigation services provided by Kazaeronavigatsia,” said Jeff Oltchick, senior manager international aviation programs with Lockheed Martin. “We are proud to be a part of their vision and to help them advance air traffic management modernization in Central Asia.”
Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 140,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2008 sales of $42.7 billion. | aerospace | 1 |

Simple physics!
To start the reason why i am actually pondering this question is because my kiddo asked santa for a space rocket to visit planets, in addition to another gift a book about planets.
So basically that got me interested in space, while on a social network i over-read something interesting, the reason why you see so much smoke when a rocket is launched into space is not due to the smoke generated by the rocket fuel but mostly is a water evaporation, what water? water in the big water pool under the rockets …. why is there a water pool ? because otherwise the amount of heat will cause the rocket to explode! I imagined that exiting the moon will require also a lot of thrust and thus we might need another water pool under the rocket on the moon, so should we take with us water for the water pool (no water on the moon)!
Some rocket science first (don’t worry it’s really simple, just try to stay focused on the main idea):
A space rocket weight on surface 250,000 pounds (113 400 kg), that’s a lot, to get the weight or the force that should be neutralized so that an object could float : W = m * ge
ge is Earth’s gravitational acceleration ,because ge depends on the distance from the center of the earth, ge is different when on surface and when in the different levels of the atmosphere, the actual value of ge is 9.8 m/sec^2 = 32.2 ft/sec^2
Once on orbit ( 200 miles from earth surface, 321 km), go is a bit lower than the ge (go / ge = .907 ), thus the shuttle should weigh 226,757 pounds NOT 0 as many might think. So in other words when in orbit shuttles and satellites are not weightless, in fact they has almost the same exact weight they had on surface, and they are not floating in space … they are falling! But because they are so high in space the earth is spinning and thus their fall is not downward because the orbital speed is tangent to the surface of the Earth, instead the fall towards the surface is exactly matched by the curvature of the Earth away from the shuttle, that means you have the impression that it does not move because earth is moving and because earth is curved, so it is constantly falling and this it’s absolute position is always changing in a way to keep it’s place relative position wise (not very important if you fail to understand the concept, but just to understand that even when in orbit the objects are falling towards earth).
So i think it’s safe to say the objective in-order to get out of a planet, is to reach the orbit and still have enough thrust in the rocket to exit the orbit, once you reach the orbit you no longer need any thrust to counter gravity you can consider the shuttle as floating , even if it is actually still falling towards earth but the fall is almost neutralized by the spinning & earth curve, but you’ll still need thrust to go up the orbit and eventually exit earth entirely and reach the moon.
Once the Shuttle reaches the moon, it can rely on the moon’s gravity to pull it down, but when leaving moon the rocket should have enough thrust to escape it and thus be able to travel towards earth, the moon has 1/6 the Earth mass thus :
gm = G * m Moon / (d Moon)^2 = 1.61 m/sec^2 = 5.3 ft/sec^2
Also moon’s orbit (known as Selenocentric orbit) is much lower than earth’s orbit, it is 62 miles (100 km) from the moon’s surface.
That means a shuttle or module needs 1.61/9.8 x 1/3 less thrust to reach the moon orbit than reaching the earth’s, that means it needs 0.055 the thrust, that’s 5.5% of the force needed for same shuttle on earth … but keep in mind that on earth the shuttle was much bigger and heavier and had to use a multistage rocket in order to lose the unnecessary weight while leaving earth …
Apollo 11 : The only human landing on the moon – July 20, 1969
To launch the Apollo 11 spacecraft, a delivery system using Saturn V rocket was used, Saturn V has 3 stages and weigh 6,200,000 pounds (2,800,000 kg), Saturn V can carry a payload of 260 000 pounds (120 000 kg) to the lower earth orbit or a payload of 100,000 pounds (45 000 kg) for trans-lunar injection (sending it to the moon).
Now let’s assume the second way round, the return to earth, we will ignore the trans-Earth injection, we will assume this stage is taken care by a lunar shuttle already in place or that split and is orbiting the moon(Columbia), to send Eagle (lunar module) and Columbia to the moon we needed a 6,200,000 pound delivery system thus we assume we need only 5% of this power to send them back to earth, that’s 310 000 pounds (140 000kg), that’s 140 000kg of pure rocket fuel, but the entire system sent by Saturn V towards the moon weigh 100,000 pounds or 45 000 kg, let’s assume that Eagle doesn’t need such a big thrust, afterall we are leaving columbia in lunar orbit, so no need to count it, assuming Eagle is 1/4th of the lunar payload, it will need 35 000 kg , again something is wrong here, Eagle needs to be the biggest part of the payload because it has the most difficult task which is leaving the moon orbit thus needs to hold fuel, but holding fuel means it will be bigger ….. for a moment let’s assume Eagle had some sort of a miracle fuel or solid fuel that needed no much space, the trans earth injection (done by columbia) needs fuel as well.
Columbia + Eagle (the payload of Saturn V)
So basically the moon shuttle needed Saturn V a 6,200,000 pound delivery system to reach the moon but had only 100,000 pound (45 000 kg) delivery system+ shuttle to return to earth from the moon! 45 000 kg is the weight of a loaded truck! , fitting a command center, navigation system + propulsion enough to escape the moon gravity in a 45 000 kg is almost impossible with current technology, let alone a technology that existed in 1969!
The Russians are still to this day skeptical that the US. landed on the moon!

Using Flight Watch
Featuring Scott Dennstaedt
"Do you have any tips on how to contact Flight Watch on a long cross country trip?"- Ron S.
"The Enroute Flight Advisory Service (EFAS), better known as Flight Watch is organized by Air Route Traffic Control Centers (ARTCCs). They can be reached on 122.0 MHz anywhere in the country between 6 a.m. and 10 p.m. local time as long as you are 5,000 feet above ground level or higher. Although in some areas you may be able to reach them at a lower altitude.
In addition to 122.0 MHz, each Center has a dedicated frequency for high altitude Flight Watch. These frequencies are listed on the inside-back cover of the green Airport/Facilities Directory (A/FD).
Flight Watch has two purposes. First, they are the primary collectors of pilot reports (PIREPs). Second, they are there to provide pilots with en route weather updates. They should not be used for full route briefings or to accept flight plans.
On any given day Flight Watch staffing is a direct function of the demand. If there's a lot of convective weather expected in the Southeast, for example, they would be sure to have additional staff on flight watch covering that region. On a very challenging weather day throughout the U.S., anticipate 20 flight watch specialists on duty or one per Center.
On the other hand, during the late evening hours or when the weather is generally tranquil and the air traffic is less, Flight Watch may drop down to as few as five specialists to cover the entire contiguous U.S.
Lastly, here are a couple of tips when calling Flight Watch. First, be sure to reference them by the name of the en route center you are located within. Second, be sure to state your location in reference to a NAVAID on the initial call. For example, if you are 20 miles north of Charleston, South Carolina VOR, you are within the Jacksonville Center airspace. You would say, Jacksonville Flight Watch, Cessna 1234B, 20 north of the Charleston V-O-R, over. This allows the Flight Watch specialist to use the best remote outlet to reach you."

An Air Canada flight was diverted to Honolulu, Hawaii, after experiencing unusually severe turbulence that left 35 passengers with minor injuries, the airline said in a statement.
Flight AC33, which was flying from Vancouver to Sydney, Australia, with 269 passengers and 15 crew onboard, "encountered unforecasted and sudden turbulence approximately two hours past Hawaii," the carrier said on Thursday.
The Boeing 777 aircraft landed in Honolulu at 12:45 pm ET (6:45 pm CET).
"As a precaution, medical personnel are on standby to examine passengers in Honolulu," the carrier said.
A passenger on the flight Sam Rattanasone posted an image of himself with a neck brace and images of the aeroplane's oxygen masks on his Instagram account.
In June, a severe case of turbulence on a flight from Kosovo to Switzerland was captured on video. Ten people were injured in the incident aboard the ALK Airlines flight from Pristina to Basel, including a member of cabin crew who was thrown into the ceiling.
Paul Williams, a professor of atmospheric science at the University of Reading, told Euronews that climate change could increase the number of such encounters with turbulence in the future.
He said: "Flight routes are planned using forecasts of clear-air turbulence, which are getting more accurate all the time, but they are still not perfect."

This provides soldiers and civilians with superior protection for both air and ground vehicles. The development was based on the growing need in the Defense Dept. for transparent armor for personnel protection and infrared windows for reconnaissance applications.
The Army UH-60M helicopter platforms use transparent armor systems mounted behind the pilots.
ALON is a transparent ceramic material composed of aluminum, oxygen, and nitrogen. It begins as a powder that is formed into shapes and made transparent by applying high temperatures and pressure. The Air Force has been working with this material since 2006. Prior to the current breakthroughs the largest ALON windows were limited to 2.8 square feet. ALON is now made routinely in sizes up to eight square feet by a small business, Surmet Corp. Scaling up is performed incrementally, due to the complex manufacturing steps that must be used. The Air Force is getting closer to providing a commodity material for government purposes.
Transparent armor is currently used on U.S. Army Blackhawk and Chinook helicopters. ALON’s excellent durability and impact resistance have also made it of interest to NASA for windows on the International Space Station.
A projectile exit point is shown in the ballistic glass (left). The aluminum oxynitride transparent ceramic armor is shown (right) with a bulge and no exit from the projectile.
The next step in protecting warfighters is creating a curved window. Curved ALON will be attempted, but it may take the use of different materials.
As longtime Trekkies will tell you, ALON was used to create a giant aquarium way back in 1986’s “Star Trek IV: The Voyage Home.” More recently, it was also used in “Jurassic World” to build a protective bubble vehicle. | aerospace | 1 |

34. On a hot day the density of the air decreases, thus reducing the mass of air entering the compressor and, consequently, the thrust of the engine for a given r.p.m. Because less power will be required to drive the compressor, the fuel control system reduces the fuel flow to maintain a constant engine rotational speed or turbine entry temperature, as appropriate; however, because of the decrease in air density, the thrust will be lower. At a temperature of 45 deg.C., depending on the type of engine, athrust loss of up to 20 per cent may be experienced. This means that some sort of thrust augmentation, such as water injection (Part 17), may be required.
|Fig. 21-8 The effect of air temperature on a typical twin-spool engine.|
36. The pressure ratio control fuel system (Part 10) schedules fuel flow to maintain a constant engine pressure ratio and, therefore, thrust below a prede- termined ambient air temperature. Above this temperature the fuel flow is automatically controlled to prevent turbine entry temperature limitations from being exceeded, thus resulting in reduced thrust and, overall, similar curve characteristics to those shown in fig. 21-8. In the instance of a triple-spool engine the pressure ratio is expressed as P 4 /P 1 . i.e. H.P. compressor delivery pressure/engine inlet pressure. | aerospace | 1 |

The biggest planes, like the Airbus A380 and the Boeing 747 are easy to spot, and always a thrill to see. If they happen to be standing next to a little Boeing 737 or Airbus A320, you can easily see how enormous they are. But I've always had trouble telling the smaller planes apart, and in particular spotting the difference between the B737 and A320. This guide by Arun Rajagopal finally gave me the clue I needed: look at how the tail fin connects to the main fuselage:
Note in the photo above (by Islam Chen), the China Southern Boeing 737 at the bottom of the frame has its tail fin connected to the fuselage with a gently sloping bracing strut. By contrast, the China Southern Airbus A320 in the middle of the frame has its tail fin connected directly to the fuselage. Other differences are apparent in the photograph, too: the lower-riding engines of the B737, and the simpler, straighter cockpit windows of the A320, but in practice I've found the tail fin difference the easiest to spot. Check out the rest of the guide to learn how to spot other aircraft in the Boeing and Airbus fleets, as well.

Water on Space Station
I wondered how does it work on space stations where natural resource does not exist and where long term isolation do not allow to refill water reserves like on transatlantic cruises or to dump waste like air plain staff do on the airports.

Hot shower or a quick splash at the lavatory is something which the astronauts can just dream of. Once on board the International Space Station, spacefarers are in for a steady diet of sponge baths using water distilled from, among other places, their crewmates breath!
The crew will eventually include lab rodents ...
... technology systems will not be useful for deeper space explorations only but it is already clear that these systems will allow many people on the Earth to have a ready access to a clean water supply. The system could be used at a wilderness research station or on a ship, for example. "The Navy has talked to us about using it on submarines," Hutchens said. "Any small remote area where you would need clean water could use this system."

If you have recently seen the sci-fi Blade Runner 2049 and was hoping it to be true someday, you need to read this. NASA (National Aeronautics and Space Administration) and taxi service provider Uber have signed an agreement to develop a future air transport system under the latter's Uber Elevate programme. The electric aircrafts that are essentially Vertical Take-Off and Landing vehicles will start its testing phase in 2020, believes Uber. Further, the company has plans of going full swing run of flying thousands of such flights transporting people by 2028.
The VTOL will be powered by an all-electric powertrain with tiltable rotors. It would look similar to some of the drones and will have complete autonomous capability. Even with all occupants on board, these VTOLs can reach a maximum speed of 322kmph claims the company. This basically means a journey that would usually take an hour and half to finish would be done in flat 15-minutes. This is not the first time that Uber has tied up to get its Uber Air program off to reality from planning stage wherein it was talking with authorities in Dallas-Fort Worth and Dubai to operate flying taxis in those regions.
Additionally, the ticket prices of the air services by Uber won't be too expensive either. According to Uber, an air taxi ride would cost similar to what an Uber X ride would cost for the same distance. The company has set its target of getting flying taxi service operational before the 2028 Olympics in Los Angeles. So the next time you are stuck in traffic, just pray that Uber's Elevate comes into reality quickly. Here is how life would look with Uber's air services.

I used the fuselage of one of my old bomber projects, if that's a problem for the challenge creator i will withdraw my entry.
About the Aircraft.
It's a Twin fuselage Heavy Ground Striker by the Blohm & Voss Company.
It uses parts from the BV 269 - Bussard bomber and adapts many of its strengths.
For example it's impressive engine array, the stable flight characteristics and the defensive capabilities.
The ordinance is doubled and it's equipped with a launch tube for a big load of anti ground missiles.
It's a very effective long range platform for the fight against large numbers of ground or naval units.

NASA scientists dubbed the sun storm a solar "Eureka! moment."
The Solar and Heliospheric Observatory (SOHO) spacecraft, which is a joint mission by NASA and the European Space Agency, snapped the new photos of the bulbous, light bulb-shaped coronal mass ejection as it erupted from the sun's surface on Aug. 20.
Coronal mass ejections (CMEs) are massive clouds of plasma and charged particles that are unleashed into space during strong solar storms. When powerful CMEs are aimed directly at Earth, they can cause geomagnetic and solar radiation storms, which have the potential to disrupt power grids and communications infrastructure on the ground. These solar eruptions can also knock out satellites in space.
The light bulb-shaped CME seen by the SOHO spacecraft has a bright core, surrounded by a very thin, wispy outer edge. It's not uncommon for CMEs to have a rounded shape, but according to NASA officials, it has been years since one took on the appearance of a light bulb.
In the new image, the white circle at the center represents the solar disk, and the photo includes the inner solar corona region up to a staggering 5.25 million miles (8.4 million kilometers) away from the sun, NASA officials said.
SOHO captured photos of the fun-shaped CME on Aug. 20, when a series of eruptions were unleashed from the sun. The spacecraft used its Large Angle and Spectrometric Coronagraph (LASCO) C2 instrument to make the observations.
This instrument is capable of snapping images of the outer layer of the sun, known as the corona, by blocking out the sun's light and creating an artificial eclipse within the instrument, NASA officials explained.
SOHO was launched into space in December 1995, and uses 12 different science instruments to stare at the sun. The spacecraft is located roughly 930,000 miles (1.5 million kilometers) away, near a region called the Lagrange Point 1 between Earth and the sun, where gravitational forces combine to create a relatively stable environment.

This was evident when the Mars Exploration Rover Spirit was immobilized in a wind blown sand dune, effectively causing the eventual end of its mission. Because there is currently no practical method of quantifying the slip and sinkage of wheels in real-time, remote rover drivers are forced to avoid areas deemed risky, resulting in either missed science or added time and energy driving to avoid hazards. Investment in this proposal will develop techniques for measuring wheel performance in real-time. On-board wheel performance measurements with hazard detection and avoidance software would allow rover drivers to operate in more hazardous driving areas by minimizing the risk of entrapment. The techniques developed could be used to enhance current rover missions and enable future rovers to explore previously unattainable areas. The goal is to investigate at least three real time techniques for measuring wheel sinkage and slip that can be implemented on the Mars 2020 rover with minimal or no impact of additional hardware. | aerospace | 1 |

“The state-owned Ukreximbank signed a loan agreement with […] the Antonov State Enterprise for almost UAH 3 billion, which will go to the construction of three new An-178 aircraft for the Ukrainian army,” he wrote on Facebook.
It is indicated that a state contract for ordering aircraft was concluded with the Ministry of Defense of Ukraine for four years in the presence and with the assistance of President of Ukraine Volodymyr Zelensky.
As reported, in late December, the Ministry of Defense of Ukraine and the Antonov State Enterprise signed a memorandum of cooperation in the construction of aircraft for the needs of the Armed Forces of Ukraine.
The Ministry of Defense of Ukraine and state-owned enterprise (SOE) Antonov signed a memorandum of cooperation in the construction of aircraft for the needs of the Armed Forces of Ukraine.
The memorandum was signed with the participation of President of Ukraine Volodymyr Zelensky, the press service of the head of state said.
At the first stage, this is about three new military transport aircraft An-178, which will receive the Armed Forces of Ukraine. They can be used for the delivery of personnel, weapons and light military equipment by landing and parachute methods, as well as for the transportation of goods.
“These new aircraft will be constructed by Ukrainian citizens, from Ukrainian components, for Ukrainian interests. Actually, the way it should be,” Zelensky said before the document signing ceremony, which took place at SOE Antonov.
The Antonov State Enterprise (Kyiv) plans to enter the final stage in terms of testing, certifying and creating a new configuration of the An-178 medium cargo transport aircraft without Russian components, State Enterprise President Oleksandr Los has said in an interview with the Ekonomichna Pravda edition.
“Beginning from January 1, 2023, we are to expand the production of An-178 to 12 aircraft per year alongside developing financial framework, expanding markets, and processing state orders from Ukrainian companies,” he said.
“This is what we obtain from the potential marketing analysis that is needed by Ukrainian state authorities and meets the demands of our potential customers,” he added.
Los explained that due to the historically existing dependence on Russian components, the An-178 is the only immediately prepared serial production to date.
“Passenger An-158 aircraft is in order, since both models are related in terms of equipment. We are also starting to work on the aircraft under the working name of An-188,” the Antonov president said.
According to him, three An-148 and ten An-158 aircraft are currently in the Antonov serial production workshops at different stages of completion.
The president of the state enterprise said that for the time being COVID-19 pandemic complicates the work of Antonov, but plans are implemented as scheduled.
“As soon as I tried to increase the number of employees, the number of COVID cases immediately increased,” Los said, adding that the chief engineer of the enterprise had recovered from coronavirus.
A Ukrainian National Guard’s Antonov An-26 aircraft has delivered medical items to deal with the coronavirus infection from China to Lviv, a report posted on the Lviv International Airport’s Facebook account says.
“Arrived! Express tests for diagnosing coronavirus, medical facemasks of various level of protection, coverall suits and other articles necessary for countering epidemic spread,” the report says.
Antonov State Enterprise (Kyiv), part of Ukroboronprom state concern, is expected by the end of the year to receive a firm order from the Interior Ministry for the production of 13 new transport An-178 aircraft with a lifting capacity of 18 tonnes for the State Emergencies Service and the National Guard of Ukraine.
According to the press service of the state concern, within a preliminary agreement of the parties announced by Interior Minister Arsen Avakov at the 53rd international aerospace show Le Bourget 2019 (France), the signing of a contract to build 13 new An-178s for the ministry agencies is scheduled for autumn.
According to President of Antonov State Enterprise Oleksandr Donets, in the near future the enterprise plans to complete the design and certification of new An-178 airplanes, which is expected to be equipped with Ukrainian, American and European equipment. The transfer of the first aircraft to the customer is preliminarily scheduled for 2021-2022.
Head of Ukroboronprom Pavlo Bukin noted the production of aircraft for the domestic customer is considered to be the key condition for the resumption of serial production of aircraft in Ukraine.
Kyiv-based Antonov State Enterprise, a leading Ukrainian designer and manufacturer of aircraft, will showcase its new projects at the 12th international Aero India Show 2019, which will be held in Bangalore, India, on February 20-24.
The An-132D lightweight multi-purpose aircraft will be shown at the static parking lot and in demonstration flights at the air show; it will become one of the new aircraft of the air show, the enterprise said on Facebook on Tuesday.
The new plant, which was developed on the basis of the An-32, a well-known transport plane in India, boasts a weight-lifting ability of 9.2 tonnes, and in future may be an effective replacement for the famous “Silver Horse” [An-32] in the Air Force of India. “Also, Antonov State Enterprise is ready to continue the program of cooperation with India for extending the resource of the existing An-32 fleet from 40 to 50 years,” the company said.
As part of India’s national programs to provide regional passenger airports and passenger transportation, Antonov will present the Regional Wings project, based on proposals for the use of An-148/158 passenger aircraft. They can work effectively in the climatic and landscape conditions of the region.
The new projects that will be presented at the air show also include a program for the creation of the An-188 military transport aircraft for short take-off and landing, the company said.
The presentation of the An-132D multi-purpose aircraft at Aero India Show 2019 is planned jointly with the Saudi partners in the project – King Abdulaziz City for Science and Technology (KACST) and TAQNIA Aeronautics Co. Currently, the partners are negotiating the development of the project and the conclusion of a contract for the finalization of the An-132D to the serial sample, Antonov told Interfax-Ukraine.
Antonov State Enterprise is the leading Ukrainian developer and manufacturer of aircraft, the world’s recognized leader in the niche of transport aircraft. By decision of the Ukrainian government, Antonov in 2015 became part of state-run Ukroboronprom Concern.
India is among the long-standing and promising partners of Ukraine, as the parties have been cooperating in the field of aircraft manufacturing and repair services for 20 years. In 2009, the parties concluded one of the largest contracts in the field of bilateral military-technical cooperation in the amount of about $400 million for the repair and retrofitting of 105 An-32 aircraft of the Indian Air Force. | aerospace | 1 |

Wing Commander Henry James (Jim) Cobb was born in Chelmsford, Essex on 31st May 1922. He was educated at Worthing High School and enlisted in the RAF at the age of 18 to train as a pilot. From September 1941 he flew Wellington bombers with 458 Squadron on operations in Europe, later in the Middle East, Egypt and Malta/the Mediterranean. After completing his first tour he returned to the UK and, after completion of specialist anti-shipping training, joined 524 Squadron flying specially modified Wellington bombers on sorties attacking E-boats and flying anti-submarine patrols off the coast of Northern France. He was awarded the DFC in 1944, followed by the DSO in 1946, the citation for the latter reading 'His record of courage and flying skill have earned him an outstanding reputation, and he sets a magnificent example.' He remained in the RAF postwar joining the Empire Test Pilot's School at Farnborough in 1952 where he joined the Armament and Guided Weapons Flight flying early jet fighters and bombers. Cobb was awarded the AFC for his work as a test pilot. In the late 1950s he was involved with the formation of the Malayan Air Force before returning to the UK as a test pilot at Boscombe and later at Farnborough where he tested pressure suits and helmets for use in V-bombers.

The Apollo lunar-landing program was the greatest triumph of America’s post-World War II can-do technological spirit. In a series of increasingly ambitious missions, NASA’s engineers and astronauts made the monumental achievement of landing men on the moon seem almost routine. Even when disaster struck Apollo 13 , Mission Control managed to bring its astronauts home safely. The only fatalities in the entire program occurred in its very first mission. Three astronauts died not while undertaking dangerous maneuvers thousands of miles from earth but while performing a routine prelaunch test on the pad at Cape Canaveral.
The date was January 27, 1967, at 18:31:04.7 Eastern Standard Time.
CHAFFEE: “Hey!” [Scuffling noise.]
CHAFFEE: “We’ve got a fire in the cockpit.”
WHITE: “Fire in the cockpit!” [Furious movement.]
CHAFFEE: “We’ve got a bad fire! Let’s get out! We’re burning up! We’re on fire! Get us out of here!”
It was over in less than 15 seconds. The astronauts—Virgil I. (“Gus”) Grissom, Edward H. White, and Roger B. Chaffee—were dead. The crew that was scheduled to pilot the first Apollo mission into space had been conducting a simulated launch countdown when the fire began. In retrospect the potential for disaster seems plain, and the events leading up to that fateful day make the astronauts’ deaths that much more haunting. But the disaster may well have saved the American space program. “We may have never gotten [to the moon] if it hadn’t been for Apollo 1 . We uncovered a whole barrel of snakes that would have given us problems later on,” said Deke Slayton, one of the original seven Mercury astronauts, who was the director of flight-crew operations for Apollo.
ON MAY 25, 1961, PRESI dent John F. Kennedy pledged that “before this decade is out,” the United States would place a man on the moon and return him safely to earth. It was the height of the Cold War, and Kennedy’s vow was meant to challenge our national pride at a time when the Soviet Union appeared to hold a firm, if early, lead in the space race. Over the next five years America began pulling ahead, launching nearly twice as many missions as the Soviets with its Mercury and Gemini programs. But ever since Sputnik in 1957, the Soviets had always managed to do things first: the first manned flight, the first woman in space, the first flight with more than one crew member, the first space walk. America’s only hope to come in first, it seemed, was to shoot for the moon. So the fledgling Apollo program, which was to fulfill Kennedy’s mandate, proceeded full speed ahead.
Apollo was a massive $24 billion effort. At its peak its contractors and facilities spanned the entire country, employing about 400,000 people and 20,000 firms. On Long Island the Grumman Corporation was developing the lunar module. The three stages of the Saturn V rocket that would propel the Apollo astronauts to the moon were being built by Boeing in Seattle and by North American Aviation (later North American Rockwell) and Douglas Aircraft (later McDonnellDouglas) in Southern California. A launch complex of unprecedented size was erected at Florida’s Cape Canaveral (later Cape Kennedy), while the famed Mission Control Center was constructed in Houston. Hundreds of contracts were let out for everything from space suits to a giant tractor used for transporting the rockets to the launch pad. The pace was frenetic, and the smallest change to one subsystem could have a ripple effect throughout the program. But America had a deadline.
For a while it didn’t seem that President Kennedy’s target could be met. In July 1963 The New York Times carried a headline proclaiming LUNAR PROGRAM IN CRISIS . The impetus for this declaration was the recent resignation of D. Brainerd Holmes, who had headed the Office of Manned Space Flight at NASA. Holmes, a highly respected engineer, had lost a power struggle with James Webb, the top man at NASA, over budget allocations and reporting responsibilities for the various components of the Apollo program. The first order of business for his replacement, George Mueller, was to conduct a realistic analysis of the status of the program. The results were not promising. The study concluded that the odds of reaching the moon by the end of the decade were only about 1 in 10 and that a lunar landing could not be attempted “with acceptable risk” until late 1971. Mueller used this dire prediction to make a radical change in the way things were done at NASA.
NASA had been testing the individual components of its spacecraft on a piecemeal basis. Everything had to work on its own before it became part of the whole. This conservative philosophy was the hallmark of the oldschool German rocket engineers at NASA, who relied on repetitive, incremental test methods to compensate for the unpredictable nature of their evolving science. So too plodded the aeronautical engineers who had come out of the flight-test field, where exhaustive ground testing in the cause of safety held sway over design expediency. But Mueller, a systems engineer from America’s ballistic-missile program, thought this cautious approach was gumming up the works. In late October 1963, a few weeks before Kennedy was assassinated, he issued an “all-up” testing mandate.
All-up testing meant that equipment had to be complete, checked out, and flight-ready when delivered to NASA, instead of requiring extensive assembly and adjustment at the Cape. Wherever possible, the various components and subsystems would be tested simultaneously under flight conditions. For example, the three stages of the Saturn rocket would first fly together instead of being tested separately beforehand. Despite the objections of staff members who thought that the Apollo spacecraft was far too complex for such a procedure, the all-up concept was put into practice. Mueller reasoned that the immense scope of the project and the interdependency of the various systems made it impossible to conduct enough repetitive testing to provide a statistically meaningful record of success. By testing different components together, each trial would yield more information. One initial skeptic was the famed rocket scientist Wernher von Braun, the director of the Marshall Space Flight Center in Huntsville, Alabama, who thought the all-up concept “sounded reckless.” But he later admitted that “without all-up testing the first manned lunar landing could not have taken place as early as 1969.”
Development of the command and service module (CSM) had been awarded to North American Aviation, whose work force was already stretched thin by its Saturn rocket contract. At first the CSM’s design effort was understaffed, and two years after receiving the contract, North American still did not have a workable design. Although the design team had expanded to some 4,000 engineers and technicians by 1964, delays and problems continued to plague development of the CSM, prompting a full-scale investigation by NASA in the fall of 1965. The subsequent report offered stinging criticism of North American and its subcontractors.
Although North American managed to deliver the first command module, designated 012, on schedule in August 1966, its relationship with NASA remained strained. Quality control was a major problem, as NASA engineers uncovered nearly 20,000 failures, errors, and omissions in CSM 012. The environmental control system had to be replaced twice. At a December 1966 press conference Joe Shea, the Apollo program manager, candidly conceded that while most of the problems were trivial, there were enough serious issues to make him apprehensive. “We hope to God there is no safety involved in the things that slip through,” he said. But Thomas Baron, a quality control inspector at North American, deemed CSM 012 “sloppy and unsafe,” while Rocco Petrone, the director of launch operations, branded it an unacceptable “bucket of bolts.” North American fired Baron for his candor, but the scheduled December 1966 launch date for the first manned Apollo mission (then known as Apollo 204 ) had to be postponed until February 1967.
On paper NASA had a “zero defects” policy regarding products delivered by its contractors. But in reality the Apollo program was fraught with oversights and expedients. The pressure to move the project along was enormous, and not simply because of Kennedy’s mandate. With the country wallowing in a sea of racial unrest, antiwar protests, and budget problems, President Lyndon B. Johnson looked to Apollo to boost the sagging popularity of his administration, and he let NASA officials know it. NASA also felt pressure from Congress, which had cut the space program’s 1967 budget by $800 million (out of about $5 billion). The quest for perfection was replaced by a policy of accepting products that were good enough to do the job.
The problems with CSM 012 gave the astronauts less opportunity to train for their mission, a shakedown flight that was scheduled to last up to two weeks. The flight simulator was supposed to mirror the production model of the CSM. But as the profusion of problems was being uncovered, engineers continued their design-on-the-fly process, making more than 600 changes to CSM 012. Modification of the simulator soon lagged far behind. After personally counting more than 100 significant errors in the simulator, Grissom hung a lemon over the hatch to illustrate his disgust. But despite his dissatisfaction with the simulator and the continued delays, he remained gung ho. Like Slayton, he was one of the original Mercury seven, with the old-school test-pilot mentality. According to Grissom, the Apollo 1 mission was “primarily concerned with checking out the spacecraft’s systems and seeing whether it is flyable and livable.” If it turned out not to be, Grissom would take his chances. In early January 1967 he told a group of reporters: “We’re in a risky business, and we hope that if anything happens to us, it will not delay the program. The conquest of space is worth the risk of life.”
THOUGH IT WAS A CRITICAL step in readying Apollo 1 for flight, the test scheduled for January 26 and 27 was considered fairly routine. On launch pad 34, the much-modified CSM 012 now sat atop the Saturn IB rocket that was to carry it into space. This was to be a “plugs out” test, in which the control cables and umbilical cords between the spacecraft and the gantry would be disconnected at the end of a mock countdown, simulating conditions after launch. It was, in effect, a dress rehearsal. An unmanned version of the test was originally scheduled to be performed first, but in the spirit of Mueller’s “all-up” edict, NASA proceeded directly to simulated launch with the crew aboard.
Because the crew had performed the same checkout procedures many times in the simulator, and because the rocket was to be unfueled, the test was officially designated nonhazardous. Therefore the fire crews were on standby rather than maximum alert. Still, an atmosphere of uneasiness surrounded the test. The backup crew of Wally Schirra, Walt Cunningham, and Donn Eisele had run through a similar six-hour countdown test the day before. Later Schirra attended a debriefing with Grissom and Joe Shea.
“I don’t know, Gus,” Schirra told Grissom, “there’s nothing wrong with this ship that I can point to, but it just makes me uncomfortable. Something about it doesn’t ring right.” In the language of test pilots, the last statement was a fairly strong condemnation of CSM 012. Schirra cautioned, “If you have any problem, even a communications problem, get out of the cabin until they’ve cleared it up.”
GETTING OUT would be no small task. The Mercury capsules had been equipped with a hatch that the occupant could blow open in an emergency. Unfortunately the hatch on Liberty Bell 7 , Grissom’s Mercury capsule, had blown off accidentally when he splashed down in the Atlantic in July 1961. Fearing that an explosive hatch might do the same in space, NASA omitted it from the Gemini and Apollo capsules. But while the hatch on the Gemini capsule could be opened fairly easily, the three separate components of the Apollo hatch required at least 90 seconds to open under ideal conditions.
Schirra suggested that Shea join the Apollo 1 astronauts in the spacecraft during the test so that he could observe the problems firsthand. Shea agreed to do so but changed his mind when technicians couldn’t rig up a communications line for him to use in the capsule. With all the problems they had been experiencing, Grissom still wanted Shea to be there. He asked him to reconsider at breakfast the next day. “It’s really messy. We want you to fix it,” Grissom told Shea. But without a way to monitor communications, Shea just didn’t think it was worth it, and he again declined. Deke Slayton also considered getting into the spacecraft with Grissom but decided that he could keep an eye on things better on the ground. These decisions may have saved their lives, but they also haunted Shea and Slayton for years.
Grissom, White, and Chaffee began the plugs-out test of CSM 012 at 1:00 P.M. Things started off badly and went downhill from there. First the astronauts reported an acrid sour-milk smell emanating from the oxygen supply of the environmental control unit. The foul odor dissipated as the air was purged from the CSM and it was pressurized with pure oxygen at slightly more than atmospheric pressure. As the astronauts went through their prelaunch checkouts, the mock countdown was interrupted repeatedly because of communications problems. Static and feedback crackled over the channels, and a frustrated Grissom snapped, “How the hell can we get to the moon if we can’t even talk between two buildings?” Despite Schirra’s advice, the crew remained in the spacecraft as the test dragged on for hours.
At 4:00 P.M. the countdown was again halted while Mission Control technicians changed shifts. Over the next two hours the plugs began to be disconnected and the countdown proceeded to T minus 10 minutes to launch. Another communications failure interrupted the test at 6:20 P.M. Just under 11 minutes later Mission Control noticed a momentary power loss in the spacecraft’s electrical system. Seconds later the crew reported the fire. As the astronauts struggled in vain to open the hatch, the gantry personnel Donald Babbitt and James Cleaves rushed to their aid, followed by Jerry Hawkins, Steven Clemmons, Henry Rodgers, and L. D. Reece.
The fire raced through the capsule with lightning speed. Within 15 seconds the temperature had soared to more than 1,400°F and the pressure inside the sealed cabin had nearly doubled. The shell of the spacecraft ruptured, showering the gantry with a blast of heat, dense smoke, and molten debris, including pieces of Grissom’s space suit. The concussion threw Babbitt and Cleaves back against the gantry. Then three levels of the eight-story gantry were on fire, and attempts to reach the crew were thwarted by the oppressive heat and noxious, blinding smoke. NASA officials and launch technicians watched helplessly on their video monitors.
Alternately advancing and retreating through the choking smoke, gantry personnel beat back the flames with fire extinguishers and made their way to the hatch. Working mostly by feel, they fumbled to remove the bolts from the three-layered hatch, searing their fingers. “You couldn’t see six inches from your face,” Gleaves recalled. “I had to run my hands around the capsule to locate the hole the size of a dime into which the tool had to be inserted.” Though they could only work for seconds at a time before running back across the gantry for fresh air, they managed to remove the two outer hatches.
The inner hatch, warped from the intense heat, barely budged. Five minutes and 27 seconds after the first report of fire, they finally pried the hatch, frame and all, about six inches open. A blast of turbid smoke and intense heat belched from the cabin, driving the rescuers back once more before they could peer inside. Finally Babbitt forced the distorted hatch into the spacecraft, then collapsed in exhaustion. Reece poked his head into the cockpit and shouted, “Is anyone there? Is anyone there?” He was certain that he had heard the astronauts call out for help when the hatch was opened, but now there was no response.
The interior of CSM 012 was a mass of molten plastic and charred, twisted metal, to which the astronauts’ space suits had been fused. It took more than seven hours to remove their bodies. Contrary to published news reports, the astronauts had not been incinerated in the fire. Grissom had some burns on his right leg, and Chaffee on his back, but neither was severe enough to be fatal. Instead the crew had been asphyxiated by the poisonous fumes that had flowed into their breathing tubes. Perhaps the crudest irony of the day was that the final item on the test schedule, which had been requested by Grissom, was a simulated emergency to see how fast the astronauts could escape the spacecraft. The emergency procedures they were to follow required Grissom to unstrap himself from his couch to assist White in opening the hatch while Chaffee remained in his seat and maintained communications. The position of the bodies and the audio and film records of the test indicated that despite the terror they faced, the astronauts followed these procedures to the letter.
With a hostile Congress scheduling hearings that would not only examine the accident but determine the future of the manned space program, NASA initiated a massive investigation into the Apollo 1 fire. Twenty-one committees were created to examine every system and subsystem in the spacecraft. The screw-by-screw dissection and autopsy of the remains of CSM 012 was the most exhaustive experience of the Apollo program. The investigators produced a 3,000-page report of their findings in only nine weeks.
The report was far from the whitewash that skeptical members of Congress had predicted a NASA-led investigation would produce. It leveled unabashed, scathing criticism at both NASA and North American, citing numerous “deficiencies… in Command Module design, workmanship, and quality control.” NASA technicians were chastised for installing additional combustibles in the spacecraft. North American was faulted for delivering CSM 012 with more than 100 “open items”—that is, flaws. Company officials were accused of “ignorance, sloth, and carelessness.” An appalling level of alcohol abuse was reported among the rank-and-file workers at the plant. By the time Congress convened its hearings in April 1967, the self-criticism in the NASA report had stolen much of its thunder.
The exact origin of the fire was never determined with certainty, but the “most probable initiator” was an electrical short circuit in a cable bundle near the problematic environmental control unit. In a spacecraft that was found to have 10 times the allowable amount of combustible materials, and with a pure oxygen environment in which even so-called noncombustibles can burn, it didn’t take much of an ignition source to set the whole unit on fire.
The pure oxygen atmosphere and the existence of combustibles in the cabin had long been controversial among aerospace engineers, but until Apollo 1 NASA was firm in its resolve. The earth’s atmosphere is about 21 percent oxygen and 78 percent nitrogen. In space flight, to avoid putting a strain on the craft’s thin shell, the internal pressure is reduced to about one-third of that on earth. The partial pressure of oxygen in normal air under such conditions would be much too low to support life. In fact it takes only a moderate drop in the partial pressure of oxygen to affect brain activity.
In addition, the presence of nitrogen in the spacecraft presents a danger of its own. Astronauts exposed to a sudden change in pressure—whether due to an accident or malfunction or after donning space suits filled with low-pressure oxygen—could develop the condition known as the bends, in which nitrogen escapes from body tissues and forms gas bubbles in the bloodstream, blocking circulation. (Oxygen presents no such threat.) This illness, which was first noticed among sandhogs and is most often associated today with scuba-diving accidents, can cause neuralgic pain, difficulty in breathing, paralysis, or even death.
A pure oxygen atmosphere would provide sufficient oxygen even at the reduced pressure used in space and would purge nitrogen from the bloodstream to prevent the bends. But there was no consensus about the possible health effects of long-term exposure to pure oxygen. Soviet spacecraft had equipment that duplicated the fullpressure, two-gas environment found on earth, but they needed a thicker shell. Complex air locks were also required, and the cosmonauts had to purge the nitrogen from their bodies for hours before leaving the cabin for a space walk to protect against the bends. NASA thought that the complicated sensing and regulating system that such a scheme would require was too unreliable, and the additional tanks, piping, and controls as well as the heavier shell needed for a two-gas system would add too much weight to the spacecraft. Also, because a pure oxygen system could operate at one-third the pressure, leaks through any joints in the shell into the vacuum of space were less likely.
From NASA’s point of view, then, the case for using pure oxygen in space was overwhelming. For ground operations, the argument was less clear-cut. Indeed, the original design for the Mercury spacecraft had called for the cabin to be filled with normal air while on the launch pad. As it ascended into orbit, the air would be bled from the cabin and replaced with pure oxygen as the external atmosphere thinned. By the time it reached space, the craft would contain about two-thirds oxygen and only one-third nitrogen at a total pressure of approximately 5 psi, although the astronaut would breathe pure oxygen at the same pressure through his space suit at all times (unlike Apollo, whose astronauts would mostly breathe the cabin atmosphere). The primary reason for this arrangement was precisely to reduce the risk of an oxygen-rich fire on the ground. Fire in space was not considered to be as serious a problem, since scientists believed that with no gravity to make hot gases rise, the flames would smother themselves in their own combustion products. In any case, an astronaut could always vent the cabin into the vacuum of space to extinguish the flames.
AN ACCIDENT DURING A ground test in April 1960 changed NASA’s thinking. A McDonnell test pilot was about one hour into a test of the environmental control system when he fell unconscious and nearly died from oxygen depletion. Because of a difference in pressure, nitrogen had leaked into his space suit from the cabin, diluting the oxygen he was breathing. Unable to eliminate the problem reliably, NASA decided that a pure oxygen environment was the best option for Mercury—not only in space but on the ground as well.
This policy was questioned within the space-flight community. In 1964, for example, two separate scientists working for NASA warned of the hazards posed by pure oxygen, which can cause fires that are virtually inextinguishable. In February 1966 an editor of Science Journal , reviewing the proceedings of a conference held the previous fall, noted a general lack of attention to launch-pad safety and predicted, “The odds are that the first casualty in space will occur on the ground.” Yet a conversion to oxygennitrogen for ground use would have introduced complications of its own at a time when NASA already had plenty to worry about. Pure oxygen at all times remained official policy in the Gemini and Apollo programs.
The question of combustible materials was raised again when CSM 012 was delivered to NASA in August 1966. Joe Shea had reiterated the firesafety requirements for the spacecraft and asked North American to investigate the problem. Within six weeks North American documented the results of a “walk-through” inspection of CSM 012 and requested specific direction from NASA on addressing them. NASA responded in turn, but given the volume of concurrent design revisions in the works, compliance was never verified.
In October 1966 Shea received a letter from a high-ranking official at another Apollo program contractor, General Electric, expressing concern that NASA had developed a false sense of security because of “the ground and flight success history of Mercury and Gemini under a 100 percent oxygen environment.” The GE official warned that “the first fire in a spacecraft may well be fatal” and suggested that NASA investigate fire detection and extinguishing options. Similar concerns were raised by Dr. Charles Berry, the chief of NASA’s medical division, who warned that even if the level of oxygen was reduced to the bare minimum, the flammable materials in CSM 012 could be ignited by a routine short circuit.
Shea responded by asking the reliability, quality, and test division of NASA to review the “nonmetallic materials control program.” Nearly two months later the division chief, Bill Bland, indicated in a report to Shea that he had not been able to carry out the review as the result of “our usual press of business with more significant problems.” But Bland said that recently completed fire-hazard assessments for the command and lunar modules had concluded that “our inherent hazards from fire in the spacecraft are low.” Even if the review had been conducted, however, a long-standing practice of the astronauts themselves might have made the results moot.
Ever since Mercury, astronauts had customized their spacecraft with nylon Raschel netting and Velcro fasteners for storing pens, flight plans, personal effects, and other items to keep them from floating about the cabin in zero gravity. It was known that these materials were combustible, but a postfire investigation showed that they practically exploded like flash paper in a pure oxygen environment. “It was unbelievable. The stuff burned like you wouldn’t imagine,” reported Tom Markley, an assistant to Shea. The investigation also revealed that netting had been installed closer to the probable ignition source than the four-inch limit stipulated by NASA fire-safety requirements.
Another focus of the investigation was CSM 017, the second command module North American delivered to NASA. It had arrived two weeks before the fire and was scheduled for use in the first flight of the Saturn V rocket, which was eventually known as Apollo 4 . CSM 017 had already passed a quality-control inspection, but now it would come under an intense scrutiny that would rival the postfire dissection of CSM 012. The inspectors found dozens of haphazardly routed and skinned wires, short circuits just waiting to happen. One by one the NASA management team came down to see the problems for themselves. Rocco Pétrone, the director of launch operations, cursed as he examined CSM 017. Joe Shea welled up in tears. Gen. Samuel Phillips, the overall Apollo program director who had led the investigation of North American two years earlier, stood in stunned silence. NASA inspectors eventually found a total of 1,407 errors in the spacecraft. CSM 017 would never fly a manned mission.
The need for a safer spacecraft was obvious, but there was no universal agreement on how to achieve that goal. Joe Shea opposed a complete overhaul, arguing that the revisions needed were fairly clear-cut. But the general sentiment within the NASA hierarchy was that a review of the entire design was necessary. Shea was soon kicked upstairs from his position as the head of the Apollo program to a behind-the-scenes job in Washington. A few months later he left NASA for good.
An additional casualty of the investigation was Harrison (“Stormy”) Storms, president of the space division at North American. Despite the problems being uncovered by the NASA investigation, Storms insisted that “there’s not a goddamn thing wrong with those spacecraft!” He dismissed the supposed flaws in the two CSMs as trivial and insisted that the blame for the tragedy lay with NASA’s decisions to use pure oxygen and a complicated, inward-opening escape hatch. His intransigent attitude was unacceptable to NASA, and North American, fearing the loss of the CSM contract, soon demoted him. That move paved the way for the eventual hiring of a nononsense engineer named John Healey to oversee production of the first revised version of the command module. This switch was perhaps the most decisive factor in North American’s recovery from the Apollo 1 disaster.
Among the changes adopted for the spacecraft were: a gas-operated, outward-opening hatch that could be operated in as little as seven seconds; flameproof coatings on wiring connections; metal shields on exposed wiring to keep the insulation from being scuffed off, which probably caused the fire; replacement of plastic devices with metal ones wherever possible; space suits and fabric surfaces made from Teflon-coated nonflammable Beta cloth, similar to fiberglass; replacement of soldered aluminum oxygen piping with stronger welded steel; and, perhaps most important, the use of a 60 percent oxygen, 40 percent nitrogen atmosphere in the cabin during ground tests. To ensure that the modifications were carried out correctly, NASA assigned a team of troubleshooters led by the astronaut Frank Borman to oversee operations at the North American manufacturing plant in California. In addition, Schirra, Cunningham, and Eisele, the crew for the next scheduled manned flight, roamed the plant floor, inspecting the production of their spacecraft, now designated CSM 101.
Shortly after CSM 101 arrived at Cape Kennedy, in May 1968, the quality-control inspectors reported that it contained “fewer discrepancies than … any spacecraft previously delivered” to NASA. That, along with the redesigned hatch and the abandonment of pure oxygen for ground tests, was the legacy of Apollo 1 . Consider the thoughts of Walt Cunningham, who rode CSM 101 on the Apollo 7 mission. “The death of Gus Grissom’s crew at the Cape made it possible to land a man on the moon on schedule. Indeed, it may have saved America’s space program. So we cannot consider their deaths to have been in vain.”
GRISSOM WOULD HAVE been proud. Shortly before his death he had written an article for the World Book Encyclopedia about his involvement in the space program. In his words, “There will be risks, as there are in any experimental program, and sooner or later, inevitably, we’re going to run head on into the law of averages and lose somebody. I hope this never happens, and with NASA’s abiding insistence on safety, perhaps it never will, but if it does I hope the American people won’t feel it’s too high a price to pay for our space program. We flew with the knowledge that if something really went wrong up there, there wasn’t the slightest hope of rescue. … There have been times when all of us have wished we’d gone in for some other line of work like, say, welding or psychology. Who hasn’t? But when the first man touches down on the moon a few years from now, well, we’ll know the whole thing has been more than worth it.” | aerospace | 1 |

The development was revealed by Stan Deal, the Chief Executive Officer (CEO) and President of Boeing Commercial Airplanes (BCA) in an email to staff on January 30, 2023, as reported by FlightGlobal. Deal noted that Boeing is “not taking the 737 out of Renton,” but rather, the company is “adding capacity to capture customer demand, especially for the newer models like the MAX-8-200 and 737-10”.
The facility, located in Renton, Washington, has housed the production of the 737, as well as other narrowbody jets produced by Boeing, such as the 707, 727, and 757, since it began developing commercial jet aircraft in the 1950s.
“In addition to preparing the facility, we have begun the process of notifying and preparing our suppliers, customers, unions, and employees as we take the necessary steps to create a new line,” Deal continued.
Currently, the manufacturer has three assembly lines in Renton. However, one is not producing any aircraft at the moment due to supply chain constraints and labor shortages. Adding a fourth line in Everett, called the North Line, will be helped by “a small group, along with some Everett teammates and some new hires,” the BCA executive said.
The North Line would replace the current 747 production facility as well as the join verification of the 787, which is checking the gaps between fuselage sections. Previously, Boeing suffered from manufacturing quality issues with the 787, which resulted in deliveries being paused between May 2021 and August 2022.
In October 2020, the planemaker announced that it would consolidate the production of the Boeing 787 in North Charleston, South Carolina, US.
“As our customers manage through the unprecedented global pandemic, to ensure the long-term success of the 787 program, we are consolidating 787 production in South Carolina,” Deal said at the time.
Following the Airbus A380 playbook
The Airbus A380 and the Boeing 747-8 share a similar story. Both Original Equipment Manufacturers (OEM) announced the two aircraft at a similar time, but with the Global Financial Crisis (GFC) having a huge impact on the economy, they never really achieved the commercial success that both OEMs had hoped for.
Airbus finally announced that production of the A380 would end sooner than planned due to a lack of orders. Several months later, the European company indicated that it would introduce an A321 Final Assembly Line (FAL) in place of the A380’s FAL.
“In order to optimize the industrial flow, we have decided to increase our global A321 production capacity and flexibility as well as to establish a next-generation Final Assembly Line in Toulouse,” said Michael Schoellhorn, the then-Chief Operating Officer (COO) of Airbus at the time. Schoellhorn has been the CEO of Airbus Defence and Space since July 1, 2021.
Prior to the 737 MAX groundings and the COVID-19 pandemic, Boeing was producing 52 aircraft of the type per month, according to comments made by then-Chairman, President, and CEO of Boeing, Dennis Muilenburg during the company’s Q1 2019 earnings call. Now, the “737 program is stabilizing production rate at 31 per month with plans to ramp production to approximately 50 per month in the 2025/2026 timeframe,” according to the Q4 2022 earnings release published by Boeing. | aerospace | 1 |

Well, you are not alone, but it is impossible, given today’s technology. Before we get into how the catastrophe would evolve, let’s first take a brief look at the evolution of flight and see where we are today.
Powered by a 12 horsepower engine, the equivalent of two hand lawnmowers, Orville Wright took off from a hill on a Kitty Hawk beach on December 17, 1903, for what would become the first-ever powered flight.
Planes were used extensively during WWI
In 1911 Italy became the first country to incorporate planes into the military during the Turkish-Italian war. During the First World War, all sides used planes extensively for recognizance, bombing, and engaging enemy aircraft. At the time, the aircraft could only operate during daylight hours as the pilots relied on ground references to know where they were.

In June 1919, Alcock and Brown took off from Nova Scotia in Canada and flew nonstop for 16 hours before crashing in a bog in Western Ireland. For the record-breaking Atlantic crossing, the converted Vickers bomber never flew higher than 12,000 feet, so there was enough oxygen in the air for the pilots to breathe. A decade later, Charles Lindbergh and Amelia Earhart became worldwide celebrities setting records of their own.
The Boeing 307 was the first pressurized airliner
The next massive revelation occurred in 1937 when the US Army Air Corps began work on the X-35, a modified Lockheed Electra with a pressurized cabin. A year later, Boeing released the Boeing 307 Stratoliner, a passenger aircraft that could fly at 20,000 feet.
The advantage to flying at higher altitudes was that the higher you got, the thinner the air was, making the plane more economical to operate. The ability to fly above the clouds also allowed pilots to avoid storms and other bad weather.
In 1949 the world was introduced to the first passenger jet airliner, the British-manufactured de Havilland Comet. Unfortunately, the plane had some design issues and had to be grounded for two years following fatal crashes. Nevertheless, it showed the world that passenger jet travel was possible. Boeing ran with the concept of jet airliners and, in the late 50s, debuted the Boeing 707. By the time various variants had been built, the Boeing 707 had a maximum ceiling of 42,000 which is where we are today.
Concorde was the exception
Concorde could fly at 60,000 feet. Photo: Getty Images.
Because the Concorde could climb and descend fast and had engines that worked in very thin air, it could fly at 60,000 but tended to cruise at an altitude of around 50,000. Other airliners would struggle to do that as there is insufficient oxygen to power the engines.
The sweet spot for modern airliners is between 35,000 and 42,000 feet, where the plane’s engines are most efficient. The way the wings are designed is also unsuitable for thin-air flight as they would not be able to create enough lift. Planes cannot just keep going up and up – at some point, it will stall.
Basically, commercial airliners cannot fly higher than their maximum rated ceiling for the following three factors:
Engine thrust: At higher altitudes where the air is thin (less dense than at lower altitudes), there is not enough air to pass through the engine for it to create the required thrust needed to keep the plane flying. The density of the air is also affected by temperature. This means the aircraft’s maximum altitude on hotter days is much lower than on colder days. The aircraft’s maximum altitude is when it reaches a point when it can no longer create enough thrust to keep climbing at least 300 feet per minute.
Cabin pressure differential: At high altitudes, the passengers would not be able to breathe if they were not in a pressurized cabin. The higher the altitude, the higher the air pressure differential between the inside and outside of the plane. At around 43,000 feet, a maximum of 9 PSI is reached, and anything higher could lead to a catastrophic structural failure of the aircraft.
Aerodynamic altitude: If a commercial airliner flies too high, it will encounter less dense air passing over the wings to create lift. This can cause the plane to stall and fall out of control. Depending on the weather conditions and aircraft weight, this can occur anywhere between 40,000 and 45,000 feet.
All airline pilots are trained to know the capabilities of the planes they are flying and ensure that everything is kept within safe margins.
In 2004 Pinnacle Airlines flight 3701 crashed after the two pilots repositioning the Bombardier CRJ200 decided to see how high the plane could go. After the plane reached 41,000 feet, its max ceiling, both engines failed. The pilots tried to restart the engines but could not before the aircraft crashed near Jefferson City Memorial Airport (JEF) in Missouri. | aerospace | 1 |

So-called white-tails are considered an alarm signal in the aerospace industry because they usually signify that they have been built without an airline in place to operate them, although in rare cases buyers can decide to paint them elsewhere.
Because of past downturns, plane makers have learned to build only what they have sold so nowadays the sight of a white plane, also known as a “ghost”, especially a recent model such as the A350, is extremely rare.
In this case, the aircraft has been sold to one of the world’s largest leasing companies, AerCap, according to online records of the serial number on the tail.
AerCap had arranged to lease it to SriLankan Airlines but its fate was thrown into doubt when the carrier said this year it had cancelled a lease for four A350s from AerCap and no longer intended to buy a further four from Airbus due to steep losses.
The Dublin-based lessor is unlikely to be out of pocket since the Sri Lankan government said last month it would pay millions of dollars for cancelling the lease.
The chief executive of Airbus’ commercial jet division said he had grown more confident of reaching this year’s target of at least 50 A350-900 deliveries.
“The objective has not changed. I visited the final assembly line last Tuesday and they are still working on 50 this year,” Fabrice Brégier said at an event marking the maiden flight of the larger A350-1000.
“I am more confident than I was at the end of June,” he said, adding: “We are now really in the ramp-up phase so we target 50 aircraft this year, or very close to it.”
But industry sources said the flexible white design raised questions about where the aircraft was headed next, which in turn echoed deeper concerns about a drop in demand for big jets.
Some online reports, however, said the jet is headed for China.
A spokeswoman for AerCap declined to comment.
The unconfirmed fate of the former SriLankan jet is a reminder of the struggles some carriers face amid fierce competition.
Its appearance in white just yards from a high-profile company ceremony was apparently an accident of scheduling in the busy Airbus delivery centre, which pumps out two planes a day.
But it struck a jarring note in an otherwise upbeat event to mark the first flight of the latest A350-1000 model, betraying a flaw in the rigid on-message flavour of such ceremonies, and intruding on the celebration like a ghost of past recessions.
“It is hard to see how that is a comforting omen,” an aviation industry source said, asking not to be named.
Without confirming whether the aircraft was destined for AerCap, an Airbus spokesman said: “We do not comment on our customers’ customers [and] we always deliver our aircraft to the customer’s specifications.”
Airbus, Boeing and many lessors say that although demand for large jets has slipped recently, the longer-term prospects for long-haul travel are robust and that jets like the A350, one of the newest types available, rarely stay unused for long.

This was the first time in India that a seaplane landed on water.mumbai Updated: Dec 10, 2017 01:18 IST
Budget carrier SpiceJet conducted the trial of a 10-seater seaplane on Saturday. This was the first time in India that a seaplane landed on water. After being delayed by more than one-and-a-half hours owing to low visibility, the amphibious aircraft landed at Girgaum Chowpatty at 3.10pm. The airlines aims to buy five 10-seater seaplanes and begin commercial operations within a year.
Sources said that Japan’s Setouchi Holdings will deliver the first batch of aircraft in next six months. With civil aviation minister Ashok Gajapathi Raju and shipping minister Nitin Gadkari on board, the aircraft took seven minutes to reach Girgaum from the Mumbai airport.
SpiceJet wants to operate 100 such aircraft with 5, 15 and 20 seats. The seaplane can fly a maximum of 1,600km at a stretch and clock speed up to 350 kmph. It requires a 300-metre airstrip to land which makes it easy to reach out to difficult, remote areas and provide them with air connectivity.
Sources said that the 10-seater aircraft costs around $4 million. “The formation of air routes takes three to six months. We are considering route suggestions from chief ministers,” said Ajay Singh, CMD of SpiceJet.
Though the airline has not disclosed potential routes, it said the seaplane will also be used for offshore oil rigs and emergencies. Officials said the airline wanted to focus on remote areas.
Kazuyuki Okada, president and CEO, Setouchi Holdings, said, “Kodiaks are the perfect flying machines to effectively connect remote cities.” Vipul Saxena, an expert, termed the entry of amphibian aircraft revolutionary. He cautioned the authorities to put in place a robust management system for safety of fliers.

You are—and there are times when it pays to keep that in mind while receiving VFR traffic advisories, also known as flight following, from an ATC facility such as a terminal radar approach control (tracon).
The Class D airspace ceiling up ahead is 2,800 feet msl, and you were planning to overfly it at 3,500 feet eastbound. But an overcast in the area is lower than was forecast, so you are approaching the Class D airspace boundary at 2,000 feet to maintain VFR conditions.
Is your flight authorized to proceed through the Class D airspace?
This isn’t Class B airspace, which you would not fly through without receiving specific clearance into the airspace.
It isn’t Class C airspace, which requires you to establish two-way communications—a step you have already taken.
This is Class D airspace, and you remember learning that “when arriving, departing, or passing through Class D airspace, communications must be established with the tower.”
Today, however, you are already in contact with ATC in the person of the tracon’s radar controller, who has issued no cautions about your imminent penetration of the Class D airspace ahead. Does that suffice as the required two-way communications?
No. The catch is that the tracon is not the controlling agency for the Class D airspace. This is an odd scenario—and fortunately, an uncommon one—in which it is necessary for the VFR pilot to work with two ATC facilities simultaneously.
Typically, the radar controller will work out your passage with the tower, according to controller Joseph Mash, who addressed the issue in this AOPA Air Safety Institute Ask ATC video.
But if you have any doubt, take charge by asking whether you should switch frequencies and call the tower.
"It’s the best way to handle it for sure,” Mash said.

● mu Space is granted A1 level of investment promotion incentives and privileges, the highest rank of any eligible incentives, with the manufacturing of its small satellite components in a category of high technology industry; Manufacture or repair of Aircraft, or Aerospace Devices and Equipment section.
● BOI incentives and privileges will benefit mu Space’s business operations as well as the development of the country’s economy.
● The company aims to enhance Thailand’s competence as a strong player to equally compete in the global space industry.
Bangkok, 29 March 2021 - Satellite and space technology company, mu Space and Advanced Technology Co., Ltd., has secured a Thailand Board of Investment (BOI) investment promotion to take on the international space technology market.
mu Space is granted A1 level of investment promotion incentives and privileges, the highest rank of any eligible incentives, with the manufacturing of its small satellite components in a category of high technology industry; Manufacture or repair of Aircraft, or Aerospace Devices and Equipment section.
The company aims to be the leader and put Thai space-tech company on the map. Its investment plan focuses on two aspects including machinery and Research & Development (R&D).
The main objective of mu Space’s investment in machinery is to serve the manufacturing process . These machines include raw materials and equipment both domestically and internationally such as 3D Printer or Additive Manufacturing, CNC Machine, Robotic Arms, Attitude Control Test Bed, Air Bearing, Helmholtz Cage, and Sun Simulator. For investments in R&D and spacecraft engineering systems, the company plans to impart knowledge on satellites and space technology.
mu Space’s founder and CEO, James Varayuth Yenbamroong says “innovations that blend technology and art need the use of knowledge on real science, engineering, and fundamental thinking that our team has implemented on earnestly.” For this reason, the company is able to create credibility and earn trust from leading organisations in business partnerships and investments. The CEO strongly views the company’s young team members as mu Space’s strength, he says “we have a group of young generations that have high capability. Thailand also has the advantages of natural resources and energy as well as existing infrastructures from heavy industry like automotive manufacturing.”
With earnest work ethics and a strong investment plan, mu space is granted BOI incentives and privileges including 8 years of exemption of corporate income tax, exemption of import duties on machinery, exemption of import duties on raw materials used in R&D, exemption of import duties on raw materials used in production of export, as well as merit on decentralization which is a 50 percent reduction of income tax for another 5 years, along with other privileges that are not tax related.
The incentives and privileges will benefit mu Space’s business operations including cost saving (raw materials and tax exemption), knowledge management and talent creation, along with accelerated business growth. Not only will BOI incentives help with the business operations but also the development of the country’s economy. There will be more job opportunities especially highly skilled labor in the fast-growing space technology industry.
“Our plan in the recent 3-5 years is generating thousands of highly paid jobs, raising higher payments for talents in the new technology circle, and boosting more trading within the community. We hope to eventually establish a high technology ecosystem that attracts people’s attention and interest in technology”, says James.
Key groups of mu space’s clients are private companies such as telecommunications and internet service providers, state enterprises such as space and defense agencies, heavy industry, and other aerospace companies. “We are the first mover in Asean and often compared with other players in Europe, the US, and Australia. What we have already invested will begin to take off within the next 3-5 years”, adds the CEO.
mu space team is currently developing Space Internet Data Center (IDC). The company is also expanding its operations to a new factory (size M) which is 10 times bigger than its original one and helps increase production capacity. The company is planning to launch its self-developed satellite and space technology at the mu space’s technology day event. This satellite will have its first actual test launch into space and will be ready for service within 2021.
One of James’ and his team’s ultimate goals is to enhance Thailand’s competence as a strong competitor in the global space industry. “I want to help Thai people push beyond their limits. We aspire to become global citizens because our younger generations are highly visionary and ready to set about doing the work”, says James. | aerospace | 1 |
