"So, not in the foreseeable future"

I agree, but the point was they are tied to NASA and NASA's projects for the foreseeable future, not that they are going away tomorrow.

"But I don't think that manned flight to Mars is wild and unattainable fantasy"

It wasn't too long ago you were talking about colonization. So which is it? Colonization or a manned flight?

Yeah I believe a manned flight is possible. If we were really motivated it would have been possible before my lifetime, certainly before SpaceX.

Colonization is leaps and bounds beyond that.

"Mars is still a pipe dream."

Well, I reacted to this sentence, which is a bit ambiguous. But I don't think there is a big gap between manned flight and colonization in case of Mars. Mars is very far, which means that from the very beginning, the crews will have to maximize their independence from the Earth.

You can supply Moon bases by cargo from the Earth easily, but people on Mars, even if only dozens during the initial period, will have to optimize everything for self-sufficiency as much as possible.

And if you prioritize self-sufficiency, you need more people, more robots, more factories = in a word, colonization comes naturally from that.

That's because you think the problem is getting there. Staying there is the real problem, and it's one that hasn't had any real advances. It's why things like Artemis are important and colonization of Mars is still a fantasy.

I tried to explain my opinion in my previous comment.

In the case of Mars, the gap between getting there and staying there is much, much smaller than in the case of Earth orbit or even the Moon. It is just too far for Earth to be of any help. Whatever goes wrong, the astronauts will have to solve on their own. Which means that they must be prepared for a very wide spectrum of adverse events.

This is a good fundament for a very resilient settlement - out of need.

Isn't that a question of incentives, though?

Modern people residing on Earth don't generally have to be self sufficient for months. Even in isolated places like the South Pole during winter, windows of opportunity for transport to civilization open here and now.

On the other hand, the Sentinelese are self sufficient. Yeah, on a primitive level, but they manage it, because they simply have to. None of us here on HN would be able to live like the Sentinelese.

If someone really dumps a hundred people on a distant planet, they have to prepare the mission to be self-sufficient for at least a year or two.

Are you asking yourself?

"If someone really dumps a hundred people on a distant planet"... they die.

Yes the incentive to not die is exactly why there is a ton of work to be done before it is a practical reality.

Really, even transportation of 100 people at once is currently a fantasy.

I understand your opinion, I just disagree.

It is painfully obvious to me that we haven't even managed self sustained colonization of the most extreme environments of Earth. Mars isn't just going to happen by accident because someone flies there.

Additionally, SpaceX is not going to manage it alone when a manned flight does happen. It will be NASA's Artemis program.
