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.
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
I suppose it’s good science to figure out if we can do it, just like it’s good science to see if we can establish more access to space
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 Falcon 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. Heck, it’s probably cheaper than our little tantrum in Iran and certainly for a better purpose
