I really think you are under estimating things here. The trip to mars is ~145x longer (at minimum!) than the trip to the moon. Let's say it only takes us twice the time to develop a rocket & ship that can do that (and come back ofc) - so that's 20 years (for 145x the distance). Then you gotta develop structures and building techniques, some of which you can look at with robots, but some of which will need human feedback. The trip itself takes 7~10 months, adding extra time. If all of humanity devoted ourselves to setting up a mars base it would take less than 100 years! My timeline was based on NASA with 2-4x the budget, which I think is very reasonable. I think you are being foolish.

Yes, the quote "a million earthlings will be living on Mars in 20 years", is hilarious. It would require us to start launching hundreds of SpaceX Starship rockets a day every day, now. It's just dumb. I know that there can be an amazing level of self confidence and denial of current reality required to build a new company from scratch, but this stretches all bounds of credulity. I just don't believe that they believe what they're saying. It's so far beyond marketing hype and "self driving" being available in 2018. At some point, this moves from encouraging hype to pure cult level deceit.

  Remember that the quote is coming from the same guy who has been promising FSD for years and hasn't come any closer to delivering it because it turns out that the devil is in the details. Elon Musk allegedly has a photographic memory that allows him to commit entire science books to memory but he apparently fails to appreciate real-world complexity. Even if you would want to give him credit for being a hype man, ideas guy, visionary, whatever, it's pretty obvious that he doesn't concern himself with the nitty gritty of every step of the way and he also doesn't seem to actually conceptualize them. It's very much like the reasoning problem many of us software developers face: because we're used to working in extremely complex business domains without having actual real-world domain expertise, we overestimate our understanding of those domains and thus underestimate the complexity of various domains in general. We look at problems, recognize patterns we're familiar with and think the problem is trivial to solve. Hence "second system syndrome" and all that - even when looking at software we underestimate the complexity because we see the general structure and mistake the complexity for cruft.

The goal was "get a few humans on Mars". Not the insane goal of "a million in 20 years". Firstly, there's no reason the trip can't be one-way, or at least, temporarily one-way. Secondly, there's not a huge need to develop a new rocket. We've delivered lots of one-way cargo to Mars using the Atlas V; something like the SLS could deliver much more, plenty for a couple humans to get there and not die. We've already launched SLS uncrewed around the moon, there's no reason to think it would take decades of dedication to launch one again 1-way to Mars.

  I think you're imagining a limited mission that's pretty far outside the tradition of space travel up 'til today. Consider the public reaction to Apollo 13 or Vladimir Komarov. Certainly, we could deliver a one-way small number of people more quickly, but I didn't think that's what we were talking about (it's certainly not what the article is talking about). Edit: I suppose I should have said "a few humans [permanently settled] on mars, [able to return whenever they like]" in 100 years.

    I suppose grandparent comment is saying that a possible timeline is to send some people there today and finish building the rocket to pick them up and bring them back in say 5 years. A bit like the Boeing clusterfuck last year... It'd also be cool to send an empty rocket with auto-landing capabilities and supplies way before the manned mission, and when those Mars visitors arrive, they can move the tech needed for survival (which would've been invented/improved in-between) to the return rocket. But that all sounds like Kerbal scenarios rather than real life ones.

  We also haven't specified if we're sending live humans to Mars. Just shuck someone onto the next rover we send over and call it a night. Sending a live human, or group of humans, on a suicide mission in the name of bragging rights as a species would be really bleak. I doubt you'd get much political support for a Mars mission without a return plan, or at least a sustainability plan.

This is a dumb argument. We are doing it now, already, no crazy budget explosions needed. Just some medium expansions of existing projects. Orion is going to send humans past the moon this year, and could theoretically send humans to mars not much further out than that. It is literally on the Lockheed Martin website that they would like to send humans to mars sometime in the 2030s, provided they can get the funding. I'm not involved in the project any longer, but this has been the ideal vision of the project since the mid 2010s. Currently the plan is to put people on the moons of mars, as we have no way of getting them back if we actually put people on the surface of mars.
