We don't need to make it work.You've missed the point that I was trying to make. The fact that we can't make it happen here in the most optimal of environs means that it will be far more difficult in a place where people can't just walk out of the experiment if things go sideways fast.
That's correct. I'm saying it isn't a must. Getting resources from Earth is a thing. Getting local resources is eventually a thing. We don't need a closed life support system. It's not a requirement. Stop trying to claim this is all doomed consequence of our inability to create such an unnecessary thing.I'm not saying it isn't a must. But it is going to take time to spin up any appreciable ISRU at the scales to sustain a human presence off-planet. And some resources may have to be sourced from Earth indefinitely.
What's the economic interest in Antarctica or the ISS?Antarctica is on Earth, last time I checked. The ISS is in a very low orbit, basically still on Earth on a cosmic scale, and astronauts live there for much shorter periods of time than what would be necessary for Mars or the Moon. Neither is remotely comparable to Mars or even the Moon in terms of resources, energy, and money needed. And it is unclear that the ISS is here to stay long term anyways.
Hearing that the company is run by an asshole is the side effect of following a company run by an asshole, so I’m not sure what you were expecting.You're onto something with that analogy but your conclusion is exactly backwards. The comments from the engineers on this thread are very supportive of going to Mars and eager to discuss how SpaceX might solve the remaining engineering challenges. The manager types constantly spew uninformed drivel about how we can't possibly do it or it's too dangerous without quantifying anything. And a good percentage are just here to remind everyone that Musk is an asshole which I think everyone is well aware of and I am personally very tired of hearing about on every SpaceX article.
Sincerely,
An engineer
Mars has nothing for us that we don't have here on Earth, but if someone must go, let it be Musk.
Other than obscure peculiarities like F1 engines?Can anyone name a single technological achievement we made 56 years ago that we still can’t replicate today?
There is no need of such a strong economic interest, because it is orders of magnitudes easier to be in Antarctica or on the ISS than on Mars or the Moon.What's the economic interest in Antarctica or the ISS?

Interesting. What money has he taken that is not based on contract obligations being fulfilled?so. he’s giving the money back?
The issue is that it is the same boring conversation in every article. It goes something like this.Hearing that the company is run by an asshole is the side effect of following a company run by an asshole, so I’m not sure what you were expecting.
No. We should send along his trusty sidekick Donald Trump, too.The first human flight to Mars needs to have Elmo, and only Elmo, on board. If the flight never returns because it was built to the same manufacturing standards as the Cybertruck, oh well, lesson learned.
Where in history do we actually have record of that happening? Humans spread across the world before written history, and usually even before oral history. The first colonists are often oppressed, but always alongside the aborigines.History is very clear. When they are no indigenous people to oppress, the first colonists assume that role.
He totally missed a trick with that one. He should have gone with Kakos Maximus. (For those who don't speak Ancient Greek, Κακός means sick/bad. The Romans loved Greek loanwords, so using a Greek first name would be fine.)Musk? You mean the guy who just changed his name on
'Cacus Maximus'* would have worked as well, being from the same Ancient Greek root, but in Latin. Anyways, it's really funny how the modern fascists mangle up the classical Latin or Greek while drawing their supposed ideological inspiration from it. Or perhaps just sad, them thinking they "got it right". After all, if all your historical 'inspiration' is a total chattel slavery city state like Sparta, where even the other Greek city states still practicing slavery (!) criticised Sparta for going "a bit over the top" in the slavery department, you got some problems...He totally missed a trick with that one. He should have gone with Kakos Maximus. (For those who don't speak Ancient Greek, Κακός means sick/bad. The Romans loved Greek loanwords, so using a Greek first name would be fine.)
The absolute irony of you posting this while you built a nice strawman of your own. And what is good for the goose is good for the gander.You may not agree with that, but you don't change minds with endless strings of ad hominems, unsupported assertions, and misleading to downright false facts. [emphasis added]
Earth, as a planet, has limited material resources.Establishing permanent presence on the Moon and/or Mars is not a zero-sum game. We can have both if we really want to.
China will love this.

I think before you send people you have to have the isru working. It doesn't have to be working using locally produced water. You can always brute Force that by wasting a number of starships as transporting propellant feedstock.
Either way, I doubt they send people until there's already a ship. Waiting to take them back that's fueled enough
You're right about the D-He3 reaction being harder to ignite than D-T.You're thinking of Helium-3, not Tritium. And Helium-3 is much harder to "burn". If deuterium-tritium fusion is continually 30 years off, deuterium-helium fusion is more like 50 or 60.
It's also hard to think of scenarios where shipping fuel from the moon is our most economic option for power.
Musk has never considered his SpaceX goals a secret. A human settlement on Mars.well why not both? Seems to me this could be an opportunity for innovation across multiple fronts...
Probably about individuals.Just a reminder that Elon and his ilk do not give one single fuck about you.
I would say it's an order of magnitude more expensive to run a Mars mission than the ISS. The Station is really freaking expensive.There is no need of such a strong economic interest, because it is orders of magnitudes easier to be in Antarctica or on the ISS than on Mars or the Moon.
It's only a straw man if it isn't true, and did I ascribe the rhetoric in my little playlet to any specific poster (yourself included)? No. But the problem I was dramatizing is real and serious enough to prompt a content moderation policy change on this site. This is the comment I was replying to:The absolute irony of you posting this while you built a nice strawman of your own. And what is good for the goose is good for the gander.
I don't know how you interpret that, but to me it basically reads like a promise to spam these articles comment until they are unreadable. Which is what is happening, what else did we expect indeed. The space nerds epithet has been thrown around a couple of times in this comment section at least, and although I didn't see the one about Elon not buying you a pony in this one I've seen it a more than few times before. There was even someone one here saying that since right likes to lie we might as well do it (throw to the strike zone the ump is calling was I believe the phrase). I invite you to go through my comment history and find where I am engaging in ad hominem attacks.Hearing that the company is run by an asshole is the side effect of following a company run by an asshole, so I’m not sure what you were expecting.
No it isn't. He just uses that dime store philosophy to justify his abuses of peoples and systems that exist today. He's not building rockets because he genuinely, deeply believes that humanity must eventually become a multi-plant species to survive. He's building them because he's a science fiction fanboy. If he were genuinely into long-term thinking he wouldn't rush to make sure all these things happen on his watch, and in the process create businesses that become squalid hellholes of abuse and bigotry. He wouldn't be cavalier with the lives and safety of his workers. After all, what if one of them eventually produced a descendant that turned out to be the future savior of humanity? The more parsimonious explanation is that he rationalizes his selfish decisions by pretending they are necessary to bring about the techno-utopia in the far distant future, and that this end justifies nearly any means he can use.Probably about individuals.
But Elon's focus is on humanity in general and survival of the human race and human consciousness.
The government doesn't and never has subsidized the Mars dream.Neither the moon nor Mars are going to have self-sustaining colonies anytime in the near future. Which of course means that the moon -- being easier to support -- is the best near and medium term destination.
Of course Artemis is a very badly run program if we want success establishing a sustained effort yielding actual science and decades-long colonization. I'd be perfectly happy with scrapping Artemis in favour of a results-oriented program that costs far less per unit of science and/or permanent off-world structure.
The problem for Musk is that if one wants results, the moon is the far better target. If we go results-oriented, then, sure Artemis gets the axe. But so does government support for Musk's Mars dream.
That's a lot of words that can't explain why SpaceX started developing Starship on their own dime long before NASA gave them any money. It's a rocket platform that doesn't make any sense except to land 100 tonnes of material on Mars.No it isn't.

Something roboticist Rodney Brooks pointed out in his 2003 book Flesh and Machines is that all the big-name transhumanist boosters of his day kept making predictions that The Singularity which was going to make life an indescribably wondrous techno-utopia of immortal cyborg bodies and self-adapting labor robots plotted out nicely to about the time these individuals turned 75 years old, indicating that their primary motivating faith in amazing technological progress was more personal than big-picture.
You seem to be criticizing a point I never made.That's a lot of words that can't explain why SpaceX started developing Starship on their own dime long before NASA gave them any money. It's a rocket platform that doesn't make any sense except to land 100 tonnes of material on Mars.
As has been observed upthread, NASA is almost certain to tag along once it's certain that SpaceX is sending a fleet one way or another. There would be too much egg on NASA's face to not be involved.The government doesn't and never has subsidized the Mars dream.
The government pays a for profit space launch and services company (SpaceX) for completion of work done. The profits from the sale of services to others (Musk's share of Starlink's profits included) is what is subsidising the Mars dream.
Musk competes directly with the incumbents in the business of supporting NASA, the US military, and any other USG approved customer willing to pay SpaceX for the service provided. The big difference that has politicians running scared is that he does it at fixed cost and with minimal delays (compared to the industry standard) with no effort to spread the pork as widely as possible.
This failure to spend as much as possible, in as many congressional districts as possible, over the longest possible timespan defeats the basic purpose of the US space program![]()
He has no plans to. He DOES plan to use the profits from the companies he owns.Soon-to-be unelected bureaucrat has opinions about public plans for an industry that makes up a large part of his wealth.
As, to be sure, he won’t go to Mars on his own funds alone.
This reeks of conflict of interest and corruption like it rarely reeked before.
The cost is a big open question about the whole thing. Right now the state of the art for mass soft landed on Mars is half a billion for max one tonne. If that kind of cost was ever going to be politically feasible, it probably would have by now. SpaceX is hoping to up the maximum by at least a couple orders of magnitude while dropping the cost for the mission by maybe another order of magnitude. The fact that SpaceX is more than able to pick up the tab for what they've got going on in Boca Chica is encouraging on that front. If they can manage it then a lot of the assumptions about how one would go about a Mars mission go out the window.I would say it's an order of magnitude more expensive to run a Mars mission than the ISS. The Station is really freaking expensive.
And with the return that we might find life on Mars vs. ??? (what have we found in LEO?), the cost is absolutely worth the potential to find off-world life.
Nope NASA will continue to focus on the Moon and Musk will continue to focus on Mars. He will allow his paid managers to focus on the details of paying for the Mars work by selling services to anyone that needs them and can get US government approval to pay SpaceX to do the work.From TFA: "In short, NASA is likely to adopt a two-lane strategy of reaching for both the Moon and Mars."
I thought sending people to Mars was a 100% SpaceX effort. Is NASA actually likely to get involved?
Won't ever happen. He's in the history books now due to SpaceXI'd like to live in a world where this is one of the names I never hear again.
