He3? The trips will be cheap. Moon will be extended weekend trips. $10/kg to LEO. I.e. $1M for 100ton ship - compact nuclear reactor, small living quarters, 70 tons ejection mass for ionic drive - that is possible today - gets you to Mars in a few months.

And in modern attention economy there is another extremely valuable resource to mine - attention of millions. At least initially the trips by IG/TikTok influencers (would be like Jack London posting TikToks as he goes instead of writing books later) will generate tremendous revenue paving the interplanetary ways for us, mere mortals.

>Gold is way too cheap (and much easier to get on earth, even if the current mines are exhausted)

With that logic Manilla Galeons wouldn't have happened :)

Edit: just looked up prices of iridium, rhodium - $6K-$10K/ounce. So just 10kg - $2M+ . Thus it looks like there is a lot of economic sense for asteroid mining once we get to cheaply launch into LEO 100+ ton items like nuclear powered ships.

And all of this ... for gold?

(even filtering sea water for it here on earth sounds a lot cheaper)

Been hearing about the miracle of He3 for decades. Neither one of us gets off this planet alive.

I’ll get, at least for short time :) If nothing comes better, in 20-30 years retired I’ll build something like that Denmark amateur rocket. It is cheap even today, and the tech and blueprints will be widespread and available like say drones and homemade planes today.

Optimistically though I think by that time ticket to Moon on SpaceX cattle class will be $100K.
