  The huge potential of helium-3 is for nuclear fusion. Yet we don’t have fusion reactors that use helium-3 and fusion is “20 years away”. We could get to mars before needing this is any quantity

    We have lots of fusion reactors.

    They just release years of energy in a split second.

    We could get to mars

    why.

    We need to add more to that $38T debt?

      NASA as a whole is a tiny fraction of the federal budget but has always generated outsized contributions to humanity. It’s an easy argument that money spent on nasa is money earned elsewhere. It’s a good investment

      SpaceX has revolutionized space launches and I don’t believe that is government supported at all. It does fill government launch contracts but more cheaply than they could have done so themselves, and reliably enough to capture most of the world’s market. This does not add to the deficit and the early investments have been handsomely rewarded

      Both SpaceX and blue origin, as well as other new generation space companies have been much much cheaper than old style projects. Just look at Artemis for example. Huge developments costs, continually More expensive, and $1B-$2B per launch. Yet I believe the total nasa funding for the entire starship program is around not like $2B. That is a very good use of our money

    Yes, but wouldn’t it become that much easier to achieve with an effectively limitless quantity of the resource?

      I don’t know whether that is currently a bottleneck or will be any time soon. I only know we’re “20 years away” from using it regularly, just like we have been my entire life

  Which is why a smart person would have started with the moon instead of saying in 2011 that he would put a man on Mars by 2021.

    In one hand, the moon is smarter because you can have Interaction and any change takes only a week or two. While we can’t harvest local resources, the cost to location is relatively low. You could even completely run out of food and still have everyone survive

    We can’t afford to screw up anything to mars when there is no Interaction and it takes 18 months or more to make a change. Imagine if there’s a medical Emergency or the garden dies: 18 months is a really long time. Everything you send there is correspondingly more expensive and everything needs to much more stock in case anything goes wrong. There are many more possible issues to plan and prepare for. This will be especially expensive until we develop in-situ resource usage

    And we don’t even know if people could survive that long

    • mars has no magnetic field so both moon and mars are fully exposed to radiation, but an astronaut needs to survive like 3 years of it to goto mars
    • we know that microgravity causes long term health issues limiting long term presence in orbit. But we don’t know how much gravity is enough to prevent those issues. Going to the moon is short enough to not worry and gives us a second data point. Going to mars is long enough to be a serious problem if it’s gravity is not enough

      The whole Mars mission was stupid and a fantasy of scifi fans with grade 9 science. A colony, on a planet with no atmosphere and exteme temperatures, yet humans can’t handle the arctic.

        For sure it was over-hyped and jumping the gun on what’s possible. But if we ever do live off earth, mars is more likely than the moon

        Mars is also an inspirational challenge - doing something that has never been possible. Going to the moon is something we already could to half a century ago. What’s the point of doing that again?

        Assuming we do go to the moon, it had better be noticeably more than what we did 50 years ago. Personally I’m looking for a permanent moon station, similar to what ISS did for human presence in orbit

    I mean yeah, Musk is a fucking idiot that wants to retroactively prove the book he got his name from.

    At least, that’s my headcanon.
