if it takes a "Space Race" with China to get the coffers flowing for NASA again I'm all for it. | r/technology | comment | r/technology | 2024-17-06 |
Food. Save for food. In the book, The Martian, they talked about it if they had missed the resupply for the trip back to Mars. | r/technology | comment | r/technology | 2024-17-06 |
We have the moon to practice with to get systems to work for the long haul. Moon- 3 days away, Mars currently six months away. | r/technology | comment | r/technology | 2024-17-06 |

It seems like you're knocking NASA, but the pen myth is a great example of the internet being wrong. [Scientific American](https://www.scientificamerican.com/article/fact-or-fiction-nasa-spen/)has an article on it.
1. Graphite dust from pencils in 0 g would accumulate over time and be dangerous to astronauts and equipment
2. NASA didn't spend 1m to make it, some private guy did and sold the pens to NASA (and others)
3. The Soviets (the clever ones in the myth) literally agreed on the danger of pencils and bought the \*same pens\* from the American company for their missions | r/technology | comment | r/technology | 2024-17-06 |
What's your favorite two? | r/technology | comment | r/technology | 2024-17-06 |
> NASA's budget has always been so low it's pathetic
The budget is only part of the problem, and probably a small one at that. Read _The Case for Mars_ and you'll get some insight into it.
A quick summary: We've had the ability to safely and reliably go to Mars since about the 70's, but government bureaucracy and contractors became obsessed with insane, impractical ideas like requiring a massive ship that could only be constructed in orbit.
SpaceX came along and did what NASA was supposed to do: build and launch spaceships efficiently and safely, and at a fraction of the cost of comparable ships. Note how NASA's equivalent projects are way over budget and don't work remotely as well (if they work at all).
**tl;dr:** Bigger problem is government bureaucracy and greedy contractors rather than the actual, technological capability to make the trip. | r/technology | comment | r/technology | 2024-17-06 |
I’ve listened to that one twice. Love it so much | r/technology | comment | r/technology | 2024-17-06 |
“Decent paycheck”
Ummm, you realize that you’d have zero need for money, right?
Once you leave earths sphere, you’re likely not coming back. If you do, you’d probably be unable to survive on earth as a normal member of society and require a lengthy rehab to just be able to walk. | r/technology | comment | r/technology | 2024-17-06 |
What about all the astronauts that spend 6-9 months in the International space station? They came back fine? | r/technology | comment | r/technology | 2024-17-06 |
Well, hope they take after the Soviet sailor who took out his own appendix and do it themselves | r/technology | comment | r/technology | 2024-17-06 |
Honestly? Hell fucking yeah. I’d volunteer for mars if they’d robotize me. | r/technology | comment | r/technology | 2024-17-06 |
Some people are going to die on the way to settling Mars. As they did settling every part of Earth and holding the settlements against the people who came after, to this day. Every person who boards a rocket will pass a course of study in this topic, be analyzed for mental fitness and sign that they understand and accept the risks.
But yeah, at least one well supplied medic on board as with the ISS and Antarctica base. Probably more on the early trips with multidisciplinary people selected. | r/technology | comment | r/technology | 2024-17-06 |
FOR THE MACHINE IS IMMORTAL | r/technology | comment | r/technology | 2024-17-06 |
Yeah you can. It just requires an extreme amount of engineering and work. It's possible.
Like, "a lack of a spinning iron core," I dunno man. Just put one in there? I understand that it would be extremely difficult and resource intensive, but I'm going to assume that asteroid mining and automated building is possible. | r/technology | comment | r/technology | 2024-17-06 |
It's always a good idea to look at the abstract and conclusion for papers that pique your interest as it can provide useful context.
> "However, our study has several limitations. [ ... ] Our simulated GCR experiments only looked at acute unfractionated dosing, which may not accurately model the chronic cumulative exposure that would happen on a Mars mission. [...] Therefore, in the absence of experiments that can more accurately model the long-term simultaneous exposure to full GCR and microgravity over several years, and the plausible synergistic impact of these insults, our results should be taken a conservative glimpse into the potential dire health consequences of long-term deep space travel. Much more intensive study of the health impacts of spaceflight on the kidneys and other visceral organs that have received little attention is of the utmost importance if we are to develop mitigation strategies and send humans to other planets and beyond."

On this weeks Science Friday Podcast, Tim Revell mentioned some of the research being done by the "Space Omics and Medical Atlas (SOMA) and international astronaut biobank", which I believe is quite relavent and worth sharing a quote from:
> "These results collectively indicate a dynamic recovery profile that substantially reverses the direction of differential gene expression in multiple key biological pathways from the post-flight timepoint (R+1) and afterward. This suggests that re-adaptation to Earth activates a range of restorative mechanisms that help recover, at least in part, the physiological stress imposed by exposure to the space environment."

I'm not in the biological fields, so take my opinion with a grain of salt. If I'm understanding the graphs correctly: This is some cool research which shows a 'decent' amount of recovery for kidney cells over time — their furthest recovery time point is only 289 days post-flight and recovery is *approaching* half of the highest effect point. I'm curious to see the recovery effects across longer time periods — 1, 2, and 3 year recovery time points — as that will show more about the *long term effects* from spaceflight on the specific cells examined.
I'd also like to see the first article team's future research with more separation between the effects from *radiation* and the effects from being in *low gravity*. It would be cool to see similar research done on astronauts/space tourists that spend their time in spacecrafts with artificial gravity (centripetal force/inertia). | r/technology | comment | r/technology | 2024-17-06 |
Yeah, that's what I was thinking too. Before we try manned missions planet, we'd first try and establish a proper self-sustaining space colony that could house a few hundred people first. | r/technology | comment | r/technology | 2024-17-06 |
Ket a day keeps kidneys away | r/technology | comment | r/technology | 2024-17-06 |
Wouldn’t this make it all the more important that we keep earth livable? Now that it’s been shown that even the billionaires with their rockets can’t escape if we eff it up in the pursuit of profit? | r/technology | comment | r/technology | 2024-17-06 |
From the Moon you can get back to Earth in a couple of days and without having to wait for the planets to line up though. | r/technology | comment | r/technology | 2024-17-06 |
Medical research like this is usually done by universities | r/technology | comment | r/technology | 2024-17-06 |
I don't think it matters whats a good motivation to me. I think it matters whats a good motivation for the people with the talent and resources necessary to develop fully functional artificial kidneys.
I think its realistically probable that developing artificial kidneys for people dying of kidney disease is not profitable, until you add in the additional incentive of unlocking the resources of space. | r/technology | comment | r/technology | 2024-17-06 |
Medical research doesn't happen at pharma companies it happens in universities and research hospitals.
You are so blindingly ignorant of the situation but wrote paragraphs about it anyways. | r/technology | comment | r/technology | 2024-17-06 |
But what if instead we find the remains of an ancient space faring civilisation, whose mysterious artifacts reveal startling new technologies? | r/technology | comment | r/technology | 2024-17-06 |
I tried watching this series but gave up in episode one of season one. Seemed to be just some boring family drama.
What is that series even about? Is it worth continuing? It was just a guy at home talking to his wife. | r/technology | comment | r/technology | 2024-17-06 |
Holy shit how many idiots wrote this exact same comments and didn't bother to read any of the replies about why thats a ridiculous response. | r/technology | comment | r/technology | 2024-17-06 |
One has nothing to do with the other. | r/technology | comment | r/technology | 2024-17-06 |
It would. The people that got us to the moon were WW2 generation accustomed to sacrifice and losses. | r/technology | comment | r/technology | 2024-17-06 |
The problem isn't that, it's being alive and useful when you get there. | r/technology | comment | r/technology | 2024-17-06 |
If we get to the point where we have virtually unlimited energy (obviously required for terraforming mars quickly) i imagine transporting or synthesizing it would be easy enough. | r/technology | comment | r/technology | 2024-17-06 |
I mean, surely it wouldn’t have a mass effect or sort. I’m sure nothing awaits us outside our galactic bubble! | r/technology | comment | r/technology | 2024-17-06 |

That's a legit proposed solution, but then the sloshing of the water in the walls becomes an issue if the entire volume is also spinning and needs to be spun up or down at all. | r/technology | comment | r/technology | 2024-17-06 |
that's easy to solve, just shield the hull with Astrophage since they block radiation | r/technology | comment | r/technology | 2024-17-06 |
I have kidneys growing out of my kidneys, like I have a around a 50% percent extra kidney tissue than normal, as if they had to double while developing but reconsidered half way through (child of mom who was a victim of Chronobyl and exposed to higher radiation levels). Couldn't they just do a similar thing and raise artificial kidneys like that that they could transplant? | r/technology | comment | r/technology | 2024-17-06 |
Got to get there faster then.
Looks like Orion's back on the menu boys! | r/technology | comment | r/technology | 2024-17-06 |
The importance of a magnetosphere is somewhat overrated. The lack of it *may* have played a role in the erosion of Mars's early athmosphere. However Venus doesn't have a magnetosphere either, yet it has the most massive athmosphere among all rocky planets and moons in the Solar System, 100 times more massive than Earth's. The second most massive athmosphere is that of Titan, even though it's a moon only about 3/4 the size of Mars the total mass of its athmosphere is about 20% more than Earth's athmosphere.
And the athmosphere erosion from solar wind is a slow process. If we somehow were able to supply Mars with an athmosphere as dense as Earth's it would take tens or even hundreds of millions of years for Mars to lose it again.
And as far as radiation protection is concerned, an Earth-like athmosphere does just fine protecting against that even without a magnetic field. | r/technology | comment | r/technology | 2024-17-06 |
God I love that movie | r/technology | comment | r/technology | 2024-17-06 |

>The kidneys are the most sensitive organs to radiation injury interestingly and it can limit cancer treatment sometimes.
Lol, no it isn't. That's thyroid. | r/technology | comment | r/technology | 2024-17-06 |
Yeah really. It is none of their business anyway | r/technology | comment | r/technology | 2024-17-06 |
All you need is a bicycle doing loops to generate artificial gravity. | r/technology | comment | r/technology | 2024-17-06 |
Shame the USSR didn’t bother researching/reporting this. They hold 9 out 10 longest space missions, some going back nearly 50yrs now.
2 were over a year duration -5x longer than any US mission. | r/technology | comment | r/technology | 2024-17-06 |

If you like the toaster fuckers I suggest the Forge of Mars series starting with Priests of Mars. https://wh40k.lexicanum.com/wiki/Priests_of_Mars_(Novel) | r/technology | comment | r/technology | 2024-17-06 |
It’s somewhat like the chicken and the egg. I’m absolutely sure that if we were to reach thousands of manned missions per year, very few would bat an eye at a couple of losses. But to get there you need to start with one and then a limited number of them. And since each of those will highly publicized, losing one will be catastrophic and cause massive delays if not a complete program termination. So without a strong motivator we might not get past this initial stage or it will be a very slow and long one. | r/technology | comment | r/technology | 2024-17-06 |
Most versions in fiction seem to be designed with a limited AI who has no goal but war which then, obviously, turns on the creator. The heroes valiantly swoop in lasers (or phasers!) blasting and somehow with just a handful of people stop this dreaded machine to discover the cause was AI bad. | r/technology | comment | r/technology | 2024-17-06 |
So we need faster space travel, space travel that doesn’t flood our atmosphere with green house gasses, a way to land ships safely on earth accurately, ships that can carry enough resources for settlements back and forth, and now artificial kidneys.
And we aren’t even close to actually colonizing space, yet.
Space colonization is a pipe dream. Better to spend this money on stuff that actually helps us. | r/technology | comment | r/technology | 2024-17-06 |
I completely disagree | r/technology | comment | r/technology | 2024-17-06 |
Cloning would need to be significantly advanced, and some serious ethical concerns dealt with. | r/technology | comment | r/technology | 2024-17-06 |

Private interests are going to go to Mars, not government ones, for exactly this reason.
Space is full of mineral resources. And corporate interests know there are no labor protections in space. | r/technology | comment | r/technology | 2024-17-06 |
Once again, colonizing other planets sounds like something we should consider AFTER we've figured out how to put together a world government for the planet we're already on. | r/technology | comment | r/technology | 2024-17-06 |
yeh theyres a reason we come with a spare | r/technology | comment | r/technology | 2024-17-06 |
>and short of a decade of nuclear winter likely never will be.
Even nuclear war, with a winter, probably won't cause an environmental collapse to earth that renders humanity dead. The infrastructure destruction might be a concern, since most of humanity isn't self sufficient in any sense. Take out the isolated tribes somehow, and that will probably be a concern. Of course isolated tribes are isolated.. | r/technology | comment | r/technology | 2024-17-06 |
why do people assume were going straight to colonisation?
we done even have anyone living on the moon yet | r/technology | comment | r/technology | 2024-17-06 |
Good question. I have the knees of a very tall old man. I'm thinking it might be caused by the fact that I'm a very tall old man. | r/technology | comment | r/technology | 2024-17-06 |
Whether we've wanted it or not we've stepped into a manned mission to the 4th planet Mars. So let's start colonizing its volcanoes, one by one. Olympus Mons. | r/technology | comment | r/technology | 2024-17-06 |

So they bring a servant class with them, the amount of resources available means they still need to be on the departure early or they don't abandon earth. | r/technology | comment | r/technology | 2024-17-06 |
I mean... and no love for Musk this-a-way, other than him driving up property values out here where I live with his various companies springing up... but it's absolutely "possible" so long as you don't want to get back. | r/technology | comment | r/technology | 2024-17-06 |
It’s just a statement about how having different perspectives can create a better environment for advancement. Not saying that the individuals who do that specific research aren’t doing everything they can already. You are taking this very personally. And I’m not here to argue just to converse. | r/technology | comment | r/technology | 2024-17-06 |
It can, galactic radiation in Alpha, Beta, and Gamma/photon radiation. Alpha and Beta radiation are "relatively" easy to shield, Gamma is a bit harder but if you put a meter of material like water or poop on the outside of the ship then you can block photon radiation.
I'm not sure if there is any greater context but at face value that is incorrect. | r/technology | comment | r/technology | 2024-17-06 |
“The research was detailed in a paper published in the journal Nature Communications.” | r/technology | comment | r/technology | 2024-17-06 |
The first trips over there are considered one way trips. Met a guy who worked for nasa and not sure how true it is but the first 1 one flights are available for the “public” booked. The first wave astronauts who are training\applying for this also know it’s a one way trip. They expect to die on the red rock before they have an opportunity to return due to current technology. | r/technology | comment | r/technology | 2024-17-06 |

I passionately hate the Mars mission concept. It's not that I hate human progress, but it irks me to no end that people really think this is going to be the cure for overpopulation instead of investing in things the planet needs.
On top of the whole evolution thing. This is just one way to die, I guarantee there are thousands more we will discover.
