ssf redesign constellation ssf is up for redesign again let s do it right this time let s step back and consider the functionality we want microgravity vacuum process research life sciences research adaptation to space spacecraft maintenence the old nasa approach explified by shuttle and ssf so far was to centralize functionality these projects failed to meet their targets by a wide margin the military and commercial users took most of their payloads off shuttle after wasting much effort to tie their payloads to it and ssf has crumbled into disorganization and miscommunication over billion has been spent on these two projects with no reduction in launch costs and littel improvement in commercial space industrialization meanwhile military and commercial users have come up with a superior strategy for space development the constellation firstly different functions are broken down into different constellations placed in the optimal orbit for each function thus we have the gps navstar constellation in hour orbits comsats in clarke and molniya orbits etc secondly the task is distributed amongst several spacecraft in a constellation providing for redundancy and full coverage where needed ssf s main functions require quite different environments and are also prime candidates for constellization we have the makings of a microgravity constellation now comet and mir for long duration flights shuttle spacelab for short duration flights the best strategy for this area is inexpensive incremental improvement installation of u s facilities on mir shuttle mir linkup and transition from shuttle spacelab to a much less expensive ssto spacehab comet or ssto sif comet we might also expand the research program to take advantage of interesting space environments eg the high radiation van allen belt or gas plasma gradients in comet tails the comet system can be much more easily retrofitted for these tasks where a station is too large to affordably launch beyond leo we need to study life sciences not just in microgravity but also in lunar and martian gravities and in the radiation environments of deep space instead of the protected shelter of leo this is a very long term low priority project since astronauts will have little practical use in the space program until costs come down orders of magnitude furthermore using astronauts severely restricts the scope of the investigation and the sample size so i propose labratsat a constellation tether bolo satellites that test out various levels of gravity in super van allen belt orbits that are representative of the radiation environment encountered on earth moon earth mars earth asteroid etc trips the miniaturized life support machinery might be operated real time from earth thru a vr interface after several orbital missions have been flown follow ons can act as ldefs on the lunar and martian surface testing out the actual environment at low cost before billions are spent on astronauts by far the largest market for spacecraft servicing is in clarke orbit i propose a fleet of small teleoperated robots and small test satellites on which ground engineers can practice their skills once in place robots can pry stuck solar arrays and antennas attach solar battery power packs inject fuel etc once the fleet is working it can be spun off to commercial company s who can work with the comsat companies to develop comsat replaceable module standards by applying the successful constellation strategy and getting rid of the failed centralized strategy of sts and old ssf we have radically improved the capability of the program while greatly cutting its cost for a fraction of ssf s pricetag we can fix satellites where the satellites are we can study life s adaptation to a much large more representative variety of space environments and we can do microgravity and vacuum research inexpensively and if needed in special purpose orbits n b we can apply the constellation strategy to space exploration as well greatly cutting its cost and increasing its functionality mars network and artemis are two good examples of this more ambitiously we can set up a network of native propellant plants on mars that can be used to fuel planet wide rover ballistic hopper prospecting and sample return the descendants of labratsat s technology can be used as a mars surface ldef and to test out closed ecology greenhouses on mars at low cost nick szabo szabo techboook com

re market or gov failures in c tcl xi cs cmu edu tm msu edu tom writes fred saying that gov coercive poser is necessary for any space program i reply btw fred you ve really crossed the border since you admit that the ideas you support can only be carried out with coercive power now that s really f in intolerant so get off yer high horse about tolerance fred replies no tommy i admit that there are such things as market failures which necessitate intervention by other than capitalist forces to correct i guess your understanding of this market failure should be classified under phil s economics on the level of th century medicine since you apparently completely ignored that this market failure can as easily or even much more easily be attributed to government intervention failure so in addition to a strong moral argument against what you propose there is also a strong utilitarian argument namely that gov s destruction of wealth through confiscastory taxation and redistribution on a major scale has made significant private capital investments harder to make i note that you make no such case as you claim can be even more easily made yes the argument can and has been made that current government policy creates even larger market barriers than there were in the first place but there is no such term as government failure since the government can change policies whenever it pleases the market doesn t do that and is governed by relatively well understood forces this libertopican bilge about moral arguments about taxation etc is at bottom so much simplistic economic thinking it can only be justified by cliche derision of anyone who knows more about economics than the libertopian which is what invariably happens tripe a la tommy the new libertopian dish get a clue little boy and go salve your wounded pride in my not considering you infallible in some other fashion i m not interested in your ego games puh leese fred this besides being simply an attempt to be insulting really belongs on private mail if ego games are so unimportatnt to you why the insults and this strange negative attatchment for me wherever do you get this inflated idea of your own importance insisting on perfect safety is for people who don t have the balls to live in the real world mary shafer nasa ames dryden fred mccall dseg ti com i don t speak for others and they don t speak for me

re what if the ussr had reached the moon first jgreen trumpet calpoly edu james thomas green writes if they had beaten us i speculate that the us would have gone head and done some landings but we also would have been more determined to set up a base both in earth orbit and on the moon whether or not we would be on mars by now would depend upon whether the soviets tried to go setting up a lunar base would have stretched the budgets of both nations and i think that the military value of a lunar base would outweigh the value of going to mars at least in the short run thus we would have concentrated on the moon great speculation i remember being proud on behalf of all the free world you think that way when you are seven years old that we had got there first now i m almost sorry that it worked out that way i guess the soviets would have taken the victory seriously too and would almost certainly not have fallen victim to the complacency that overtook the us program perhaps stretching to match us efforts would have destabilized them sooner than it did in fact and in the tradition of marvel comics what if this destabilization in the brezhnev era might have triggered the third world war hmm maybe it was a giant leap after all internet pete extro su oz au accept everything uucp uunet mcvax munnari extro pete reject nothing

re pushing the envelope in apr princeton edu lije cognito princeton edu elijah millgram writes a friend of mine and i were wondering where the expression pushing the envelope comes from anyone out there know every aircraft has flight constraints for speed aoa power when graphed these define the flight envelope of that aircraft presumably so named because the graphed line encloses envelopes the area on the graph that represents conditions where the aircraft doesn t fall out of the sky hence pushing the envelope becomes operating at or beyond the edge of the flight or operational envelope note that the envelope isn t precisely known until someone actually flies the airplane in those regions up to that point all there are are the theoretical predictions hence one of the things test pilots do for a living is push the envelope to find out how close the correspondence between the paper airplane and the metal one is in essence pushing back the edges of the theoretical envelope to where the airplane actually starts to fail to fly note too that this is done is a quite calculated and careful way flight tests are generally carefully coreographed and just what is going to be pushed and how far is precisely planned despite occasional deviations from plans such as the early first flight of the f during its high speed taxi tests i m sure mary can tell you everything you ever wanted to know about this process and then some insisting on perfect safety is for people who don t have the balls to live in the real world mary shafer nasa ames dryden fred mccall dseg ti com i don t speak for others and they don t speak for me

aerospace companies cooperate in reusable vehicle market what would all of you out there in net land think of the big martin mariatta boeing mcdonell douglas general dynamics lockheed rockwell getting together and forming a consortium to study exactly what the market price pints are for building reusable launch vehicles and spending say million to do that recognizing that most of the military requirements for launch vehicles are pulled out of a hat somewhere say has the shuttle ever really used that mi crossrange capability you get the idea figure out how many how often where to etc then taking this data and forming a sematech type company bad example i know but at least its an example to develop between and craft designs then to take all of those designs and figure out exactly what the technologies are and demonstrate those technologies in order to eliminate designs that can t be built today and lets say that this portion again funded by the gov cost about million and from here all of these companies went their separate ways with the intention of taking all of the market data and the design data to wall street and saying i want to build this vehicle and here are the numbers that show roi fund me now many of you think that this is a joke but i have it on good authority that just this project is shaping up in the background it seems that the aerospace companies have learned that everyone yelling similar but different things ends up in many programs that do nothing much and get canceled nasp nls als dcy etc they need to work more in the japaneese and european spirit of initial cooperation they have also learned that design requirements that are phony i e some generals idea of what a space vehicle ought to be ends up getting chopped up in congress because it is not a real requirement any feedback john

ssto senatorial aide breifing recollections the following are my thoughts on a meeting that i hugh kelso and bob lilly had with an aide of sen patty murrays we were there to discuss ssto and commercial space this is how it went after receiving a packet containing a presentation on the benifits of ssto i called and tried to schedule a meeting with our local senator d patty murray washington state i started asking for an hour and when i heard the gasp on the end of the phone i quickly backed off to an hour later in that conversation i learned that a standard appointment is minutes we got the standard bozo treatment that is we were called back by an aide who scheduled a meeting with us in order to determine that we were not bozos and to familiarize himself with the material and to screen it to make sure that it was appropriate to take the senators time with that material well i got allocated hour with sen murrays aide and we ended up talking to him for minutes with us ending the meeting and him still listening we covered a lot of ground and only a little tiny bit was dcx specific most of it was a single stage reusable vehicle primer there was another woman there who took copius quantities of notes on every topic that we brought up but with murray being new we wanted to entrench ourselves as non corporate aligned i e not speaking for boeing local citizens interentested in space so we spent a lot of time covering the benifits of lower cost access to leo solar power satellites are a big focus here so we hit them as becoming feasible with lower cost access and we hit the environmental stand on that we hit the tourism angle and i left a copy of the patric collins tourism paper with side notes being that everyone who goes into space and sees the atmosphere becomes more of an environmentalist esp after seeing the smog over l a we hit on the benifits of studying bone decalcification which is more pronounced in space and said that that had potential to lead to understanding of and maybe a cure for osteoporosis we hit the education whereby kids get enthused by space but as they get older and find out that they havent a hop in hell of actually getting there they go on to other fields with low cost to orbit the chances they might get there someday would provide greater incentive to hit the harder classes needed we hit a little of the get nasa out of the operational launch vehicle business angle we hit the lower cost of satellite launches gps navigation personal communicators tellecommunications new services etc jobs provided in those sectors jobs provided building the thing balance of trade improvement etc we mentioned that skypix would benifit from lower launch costs we left the paper on what technologies needed to be invested in in order to make this even easier to do and he asked questions on this point we ended by telling her that we wanted her to be aware that efforts are proceeding in this area and that we want to make sure that the results from these efforts are not lost much like condor or majellan and most importantly we asked that she help fund further efforts along the lines of lowering the cost to leo in the middle we also gave a little speal about the lunar resource data purchase act and the guy filed it separately he was very interested in it he asked some questions about it and seemed like he wanted to jump on it and contact some of the people involved with it so something may actually happen immediatly there the last two things we did were to make sure that they knew that we knew a lot of people in the space arena here in town and that they could feel free to call us any time with questions and if we didn t know the answers that we would see to it that they questions got to people who really did know the answers then finally we asked for an appointment with the senator herself he said that we would get on the list and he also said that knowing her this would be something that she would be very interested in although they do have a time problem getting her scheduled since she is only in the state week out of these days all in all we felt like we did a pretty good job john

re vulcan no not the guy with the ears in article vnci b w w inqmind bison mb ca victor inqmind bison mb ca victor laking writes does anyone have any info on the apparent sightings of vulcan all that i know is that there were apparently two sightings at drastically different times of a small planet that was inside mercury s orbit beyond that i have no other info the sightings were apparently spurious there is no planet inside of the orbit of mercury the idea of vulcan came from the differences between mercury s observed perihelion precession and the value it should have had according to newtonian physics leverrier made an extensive set of observations and calculations during the mid th century and simon newcombe later improved on the observations and re calculated using leverrier s system of equations now leverrier was one of the co discoverers of neptune and since he had predicted its existence based on anomalies in the orbit of uranus his inclination was to believe the same sort of thing was afoot with mercury but alas twere not so mercury s perihelion precesses at the rate it does because the space where it resides near the sun is significantly curved due to the sun s mass this explanation had to wait until and albert einstein s synthesis of his earlier theory of the electrodynamics of moving bodies commonly called special relativity with reimanian geometry the result was the general theory of relativity and one of it s most noteworthy strengths is that it accounts for the precession of mercury s perihelion almost exactly exactly if you use newcomb s numbers rather than leverrier s of course not everybody believes einstein and that s fine but subsequent efforts to find any planets closer to the sun than mercury using radar have been fruitless bill gawne forgive him he is a barbarian who thinks the customs of his tribe are the laws of the universe g j caesar any opinions are my own nothing in this post constitutes an official statement from any person or organization

re the area rule i am sure mary or henry can describe this more aptly then me but here is how i understand it at speed near supersonic the wind behaves like a fluid pipe it becomes incompressible so wind has to bend away from the wing edges as the wing thickens the more the pipes bend if they have no place to go they begin to stall and force compression stealing power from the vehicle high drag if you squeeze the fuselage so that these pipes have aplace to bend into then drag is reduced essentially teh cross sectional area of the aircraft shoulf remain constant for all areas of the fuselage that is where the wings are subtract teh cross sectional area of the wings from the fuselage pat

gibbons outlines ssf redesign guidance nasa headquarters distributed the following press release today i ve typed it in verbatim for you folks to chew over many of the topics recently discussed on sci space are covered in this gibbons outlines space station redesign guidance dr john h gibbons director office of science and technology policy outlined to the members designate of the advisory committee on the redesign of the space station on april three budget options as guidance to the committee in their deliberations on the redesign of the space station a low option of billion a mid range option of billion and a high option of billion will be considered by the committee each option would cover the total expenditures for space station from fiscal year through and would include funds for development operations utilization shuttle integration facilities research operations support transition cost and also must include adequate program reserves to insure program implementation within the available funds over the next years billion is reserved within the nasa budget for the president s new technology investment as a result station options above billion must be accompanied by offsetting reductions in the rest of the nasa budget for example a space station option of billion would require billion in offsets from the nasa budget over the next years gibbons presented the information at an organizational session of the advisory committee generally the members designate focused upon administrative topics and used the session to get acquainted they also received a legal and ethics briefing and an orientation on the process the station redesign team is following to develop options for the advisory committee to consider gibbons also announced that the united states and its international partners the europeans japanese and canadians have decided after consultation to give full consideration to use of russian assets in the course of the space station redesign process to that end the russians will be asked to participate in the redesign effort on an as needed consulting basis so that the redesign team can make use of their expertise in assessing the capabilities of mir and the possible use of mir and other russian capabilities and systems the u s and international partners hope to benefit from the expertise of the russian participants in assessing russian systems and technology the overall goal of the redesign effort is to develop options for reducing station costs while preserving key research and exploration capabilities careful integration of russian assets could be a key factor in achieving that goal gibbons reiterated that president clinton is committed to the redesigned space station and to making every effort to preserve the science the technology and the jobs that the space station program represents however he also is committed to a space station that is well managed and one that does not consume the national resources which should be used to invest in the future of this industry and this nation nasa administrator daniel s goldin said the russian participation will be accomplished through the east west space science center at the university of maryland under the leadership of roald sagdeev

washington post article on ssf redesign space station redesign leader says cost goal may be impossible today the washington post ran an article with the headline shown above the article starts with a leader of the nasa team in charge of redesigning the planned space station said yesterday the job is tough and may be impossible o connor is quoted saying whether it is possible to cut costs that much and still provide for meaningful research is a real question for me o connor said everything is fair game including dropping or curtailing existing contracts with the aerospace industry chopping management of the space station program at some nasa facilities around the country working closely with the russian space station mir and using unmanned titan rockets to supplement the manned space shuttle fleet o connor says his team has reviewed design options so far and they are sorting the serious candidates into three categories based on cost the post says o connor described the design derived from the current ssf as a high cost option i believe kathy sawyer the post writer got confused here i listened in on part of o connor s briefing to the press on monday and in one part of the briefing o connor talked about how the white house wants three options sorted by cost low medium and high in another part of the briefing he discussed the three teams he has formed to look at three options ssf derivative larc modular buildup with bus msfc and single launch core wingless orbiter jsc later in response to a reporters question i thought i heard o connor say the option based on a ssf redesign was a moderate cost option in between low high cost options not the high cost option as sawyer wrote the article goes on to describe the other two options as one features modules that could gradually be fitted together in orbit similar to the russian mir the other is a core facility that could be deposited in orbit in a single launch like skylab that option would use existing hardware from the space shuttle the fuselage for example in its basic structure the last sentence in the article contradicts the title the first paragraph the sentence reads he o connor said a streamlined version of the planned space station freedom is still possible within the administration s budget guidelines

nasa wraps in the april edition of one small step for a space activist allen sherzer tim kyger write another problem is what are called wraps or sometimes the center tax when work for a large program like freedom or shuttle is performed at a nasa center the center skims off a portion which goes into what amounts to a slush fund this money is used to fund work the center manager wants to fund this sum is estimated to be over a third of the funds allocated think about that of the billion cost of freedom fully billion won t be spent on anything having anything to do with space stations now maybe that billion was wisely spent and maybe it wasn t but the work done with it should stand on its own merits not distorting the cost of other projects congress has no idea of the existense of these wraps congress has never heard the term center tax they look at the station they are getting and the price they are paying and note that it doesn t add up they wonder this blissfully unaware that a third of the money is going for something else my dear friends your mixing fact and fiction here a couple of weeks ago when i first read this in your posting i talked with one of the cost experts here in space station at headquarters if you wondering why i didn t post a response immediately i do have a real job i m supposed to be doing here at headquarters digging up old khz data looking into sherzer kyger claims rates pretty low on the totem pole of priority also i spent last weekend in kansas city at the national science teachers association conference extolling the virtues of ssf to science teachers first off yes the concept of center tax or wrap does exist if i recall the numbers correctly the total tax for the ssf program for this fiscal year is around million this was computed by adding up the wp wp and wp center taxes with the ssf budget for this fiscal year at billion my calculater says the tax percentage is over the life of the ssf program using your figure of billion for the cost of ssf a tax at a rate comes to million this is alot less than billion but i will concede it s still an appreciable amount of pocket change i should note that your estimate of the tax rate at could be close to the actual rate the tax is only charged on funds that are spent at the center kind of like mcdonalds at some states where you do have to pay sales tax if you eat the food at the restaurant but you don t if you get it take out for example at wp the vast bulk of the funds we receive go to the rocketdyne contract and are not subject to the center tax i don t have the numbers in front of me but i d guess at least of the wp funds go to rocketdyne so you could be right about a tax rate of but it s only applied to funds spent at the center and not to the prime contracts this leads to the obvious question what is the government doing with ssf funds that don t go to the prime contractors i e ok wp gets a slice of the billion pie a big portion of this slice goes to rocketdyne what happens to the balance of the funds which aren t eaten up by the center tax at wp we call these funds we spend in house supporting development funds as they are supporting the development work done by rocketdyne we have used these funds to setup our own testbed to checkout the electrical power system architecture our testbed has a real life solar array field left over from solar cell research research a few years back with lead acid car batteries to simulate the nickel hydrogen batteries on ssf dc switchgear dc dc converter units and simulated loads data from the testbed was used in a recent change evaluation involving concerns about the stability of the power system we have also used the supporting development money to purchase nickel hydrogen batteries which are on life testing at both lewis and the crane naval facility in indiana as a side point of the battery cells on test recently hit the four year life test milestone cells have completed to cycles the on orbit batteries go through cycles per year as a final example my home division at lewis used the supporting development funds to purchase personal computers and work stations for performing system analyses like modeling of the performance of the electrical power system availability calculations using a monte carlo simulation setting up a database with information on weight of the power system elements finally the money raised by the tax does not all go into a slush fund at lewis the director does control a small discretionary fund each year any individual at lewis can submit a proposal to the director to get money from this fund to look at pretty much anything within the lewis charter most of the tax however goes to fund the general services at the center like the library the central computer services division the contractor who removes the snow etc thus it is rather difficult to determine what percentage of the ssf budget doesn t go for ssf activities to get an accurate figure you would have to take the annual expenditure for the library for example and then divide by the amount of the library funds used to support ssf which would be hard to compute by itself how would you figure out what percentage of the bill for aviation week for year is billable to ssf would you base it on the person hours ssf employees spend reading av week versus the rest of the center personnel you would then have to compare this estimate of the ssf portion of the library expense with the portion of the tax that goes to support the library who knows maybe ssf overpays on the tax to run the library but we underpay for snow removal talk about a burecratic nightmare my last point is that i can t believe your claim that congress has never heard of the term center tax unfortunately all of the nasa testimony before congress isn t on a computer so i can t do a simple word search someplace to prove you wrong but surely in some gao audit somewhere these nasa cost methods were documented for congress

dc x rollout report mcdonnell douglas rolls out dc x huntington beach calif on a picture perfect southern california day mcdonnell douglas rolled out its dc x rocket ship last saturday the company hopes this single stage rocket technology demonstrator will be the first step towards a single stage to orbit ssto rocket ship the white conical vehicle was scheduled to go to the white sands missile range in new mexico this week flight tests will start in mid june although there wasn t a cloud in the noonday sky the forecast for ssto research remains cloudy the sdi organization which paid million for the dc x can t itself afford to fund full development of a follow on vehicle to get the necessary hundreds of millions required for a sub orbital dc xa sdio is passing a tin cup among its sister government agencies sdio originally funded ssto research as a way to cut the costs for orbital deployments of space based sensors and weapns however recent changes in sdi s political marching orders and budget cuts have made ssto less of a priority today the agency is more interested in using dc x as a step towards a low cost reusable sounding rocket sdio has already done briefings to other government agencies said col simon pete worden sdio s deputy for technology but worden declined to say how much the agencies would have to pony up for the program i didn t make colonel by telling my contractors how much money i have available to spend he quipped at a press conference at mcdonnell douglas astronautics headquarters while sdio has lowered its sights on the program s orbital objective agency officials hail the dc x as an example of the better faster cheaper approach to hardware development the agency believes this philosophy can produce breakthroughs that leapfrog ahead of evolutionary technology developments worden said the dc x illustrates how a build a little test a little approach can produce results on time and within budget he said the program which went from concept to hardware in around months showed how today s engineers could move beyond the miracles of our parents time the key is management worden said sdio had a very light hand on this project we had only one overworked major jess sponable although the next phase may involve more agencies worden said lean management and a sense of government industry partnership will be crucial it s essential we do not end up with a large management structure where the price goes up exponentially sdio s approach also won praise from two california members of the house science space and technology committee this is the direction we re going to have to go said rep george brown the committee s democratic chairman programs that stretch aout to years aren t sustainable nasa hasn t learned it yet sdio has rep dana rohrbacher brown s republican colleague went further joking that a shrimp is a fish designed by a nasa design team rohrbacher doubted that the program ever would have been completed if it were left to the civil space agency rohrbacher whose orange county district includes mcdonnell douglas also criticized nasa air force work on conventional multi staged rockets as placing new casings around old missile technology let s not build fancy ammunition with capsules on top let s build a spaceship although rohrbacher praised sdio s sponsorship he said the private sector needs to take the lead in developing ssto technology mcdonnell douglas which faces very uncertain prospects with its c transport and space station freedom programs were more cautious about a large private secotro commitment on very large ventures companies put in seed money said charles ordahl mcdonnell douglas senior vice president for space systems you need strong government investments while the government and industry continue to differ on funding for the dc xa they agree on continuing an incremental approach to development citing corporate history they liken the process to douglas aircraft s dc aircraft just as two earlier aircraft paved the way for the dc transport a gradual evolution in single stage rocketry could eventually lead to an orbital delta clipper dc flight tests this summer at white sands will expand the envelope of performance with successive tests increasing speed and altitude the first tests will reach feet and demonstrate hovering verticle take off and landing the second series will send the unmanned dc x up to feet the third and final series will take the craft up to feet maneuvers will become more complex on third phase the final tests will include a pitch over manever that rotates the vehicle back into a bottom down configuration for a soft four legged landing the flight test series will be supervised by charles pete conrad who performed similar maneuvers on the apollo moon landing now a mcdonnell douglas vice president conrad paised the vehicles aircraft like approach to operations features include automated check out and access panels for easy maintainance if the program moves to the next stage engine technology will become a key consideration this engine would have more thrust than the pratt whitney rl a engines used on the dc x each motor uses liquid hydrogen and liquid oxygen propellants to generate up to pounds of thrust based on the engine used in centaur upper stages the a model has a thrust champer designed for sea level operation and three to on throttling capability it also is designed for repeat firings and rapid turnaround worden said future single stage rockets could employ tri propellant engine technology developed in the former soviet union the resulting engines could burn a dense hydrocarbon fuel at takeoff and then switch to liquid hydrogen at higher altitudes the mechanism for the teaming may already be in place pratt has a technology agreement with npo energomash the design bureau responsible for the tri propellant and energia cryogenic engines

fred and tom ad naseum nick sez i m not very impressed by the old so called prospecting work from lpi it has almost all been geared towards industrially silly processes on the moon as an excuse to put astronauts there fred replies translation it doesn t support the nick szabo vision of the future to which you must subscribe tom sez fred we re all supporting what each of us thinks should be done to some degree if you have a problem with what nick thinks should be done address it instead of just complaining about his doing so fred again you really don t get what the complaints are about do you not incredibly clear explanation of complaints something between feelings regarding nick s method and judgments about his meaning t maybe i d get it if you said what the complaints are about rather than doing the same things that you mean to complain about when you trash people how am i supposed to read that as trashing people is bad f gee funny that you get it now then deliberate obtuseness perhaps fred s issue nick s alleged trashing of others i only got it when you stopped trashing and made your point patently instead of allegorically that was my point all along fred not only do you do the same thing on the net honestly reporting your ideas on matters of policy and projects in space but your response was just baiting not even part of a debate i have yet to see nick enter into anything remotely resembling a debate i see him flame anyone or anything who disagrees with the one true szabo plan i see him attacking people calling them lazy bastard because they had the temerity to disagree with the almight nick i see him questioning peoples ethics again because they had the temerity to disagree with lord god szabo but debate bwaaaaahhhaaaa i m glad you can laugh since your ratio of debate insult is about the same not even close tommy and generally only when i m dealing with someone like nick i see we are dealing with a problem in a conflict of interpretations not least of which is your belief that only you can adequately judge what is and is not debate suffice to say that i disagree with you on that last point why don t you take a poll fred if you want some psuedo objective point of view and as usual you defend your insults with he started it yeah i took some of his research and called it my own but he started it so what if i stole his car he stole my lawnmower first besides that i think it s still open to interpretation whether nick actually did start it so your defense besides being lame and contradicting the first part of the sentence in which it occurs may not even apply anyway your defense reminds me of the guy that broke the borrowed tool i never borrowed it i already gave it back and it was broken when you gave it to me make up yer mind fred i m not convinced that people are necessary in all parts of every space based process and your response doesn t tell me a thing about the reasons why you think they should be except to impune the motives of the person with a divergent opinion who said i think they should be tommy show me a note where i said that and i ll eat this terminal see below fred fred i cocluded that you did since you took issue with it the fact that my conclusion was incorrect i e that you were taking issue with something different is evidence that your communication style is confusing or evidence that your reading and comprehension style are inadequate first i try to address what i think you meant for which i am rewarded with a denial of sorts and a smart remark then i point out that i am not clear what you did mean rather than risking your childish ire wrongly interpreting you a second time and i m stupid for it i just can t win can i fred you ve got a great point here somewhere it s just that between stupid people that you must insult and your jealous guarding of your valuable opinions you never actually get around to making it please quote the it i took issue with i believe you will see if you look that what i was and am taking issue with is mr szabo s idea that the manned program should be scrapped until such time as his toaster based infrastructure is finished all hail the szabo plan fred issue nick s alleged meaning too bad the plan only exists in your mind instead of nick s or you would have a really good point instead you have provided a good reason to ignore your insults since they are based on incorrect interpretations that you have made about others forgive me for giving your insults more meaning than they ever should have had my reading of what nick actually said is that people aren t required in all parts of all space processes so your taking issue with his opinions regarding people in the space program i read as people are required in all parts of all space processes so help me out here fred since i m so patently stupid did you read nick wrong or are you going to eat your terminal now if the latter i sure hope it s one of those cheeto and string models that all the computer mags have been raving about the point is i am not stupid because of your incorrect assumption i d only be stupid if i insulted you for having made it but alas that s your job fred and finally your style is confusing since you tried to make two points simultaneously with an allegory insult sadly one point addressed a plan that only existed in your mind and the other took issue with behaviors that you do as much as anyone more deliberate lack of understanding tommy no no i finally got it you don t like the plan that nick s posts made you imagine and you don t like nick s obnoxious behavior even though it s no worse than your own thanks for taking the time with someone as dense as myself if you have a problem with nick s delivery address that the way you bait you re perpetuating the lack of discourse that you complain of no tommy the bait is that which elicits the response nick baits i just flame him for being an obnoxious fool i don t really care who started it i read this list to get information and other s views on the issues to which it was dedicated not to be your mom he started it no he did or to hear about why nick is a very bad guy if you think flaming is bad stop flaming or at least get to the point in the first post instead of explaining yourself all the time that s nice tommy when you pay me to post to the net you can complain about not getting your money s worth perhaps if you weren t deliberately too thick to get the point the first time i wouldn t have to waste time explaining myself all the time of course socrates how could it be otherwise i think it s neat how all this criticism from you started after your fatherly admonitions to me about how such things should be handled outside usenet were somewhat rebuffed being a little hypocritical tommy to go with the immaturity or is this just the pique of a net ghod wannabe who got turned down by someone he thought was new and hence could be instructed tommy i saw you come on the net who cares who came on the net first if you do consider that you saw me come on after a brief haitus before which i was on for about years if you had seen me on the net first you d remember when nick and i went down exactly the same road regarding rude unneccesary behavior it s just amazing to me that you continue to take issue with behavior that s no worse than your own let s see here my complaints about your obnoxious behavior are hypocritical while your flames against people you decide are flamers isn t and my complaints about your name calling are immature while your name calling isn t yeah right maybe if you called me some more names i might see it better fred net ghod wannabe naturally fred you ve correctly interpreted my motivations when yours are impossible to judge from your actions as your insulting of people that try proves i didn t really care about people that fill the net with personal garbage what i really wanted was to impress everyone i only put my complaints with your behavior on private mail not because it belongs there but because i thought you were such a jerk that you d bring it back to the net playing right into my hands alas i had no idea what an intellectual master you were turning tables and bringing the history of these posts to the net for the noble and valuable purpose of embarassing me whether i should feel stupid because i tried to make suggestions to such a superior intellect or becuase i tried to communicate like an adult with a self righteous ass still isn t clear well fred you exposed me now i ll never be able to get a nother job with nasa since they all know that i m stupider than fred mccall well i just hope you re happy please leave me alone now i just don t have the heart to attempt keeping up with one so far above me maybe nick or pat can approach your high standards but i m dropping it now tommy mac tom mcwilliams wk as the radius of vision increases tm ibm cl msu edu hm the circumference of mystery grows

a wrench in the works hi all i really thought that by now i would have seen something about this but i haven t so here goes last night on the evening news the anchorperson said something to the effect that one of the ssrbs that was recovered after the recent space shuttle launch was found to have a wrench of some sort rattling around apparently inside the case there was no elaboration as to where specfically the item was found of what type of wrench it was but the anchorperson did say something about a nasa official commenting that there would be an inquiry into how the thing got in the ssrb has anybody else on the net whose info sources may be better than mine heard anything about this it seems rather weird mitch jmcocker eos ncsu edu
