First of all, stop calling it “the golden asteroid.” That’s confusing people (the headline of the article linked below even uses the phrase “gold mine.” Come on, lazy journalists.)
If 16 Psyche is worth mining, when could such operations proceed? Citigroup thinks that space mining, including from the moon and asteroids, will be a $100 billion-per-year business by 2040. Launch costs will continue to decrease and experience in operating in space will continue to expand until such a business makes economic sense.

So is asteroid worth it?
Sure.
Is it horribly expensive right now?
Sure.
So why do it?
Well, how heavy do you think the materials to make buildings and ships in outer space are?
If we’re serious about putting people on the Moon and Mars, then it makes much more sense to set up robotic mining factories and assemble everything in space.
All this needs is a little incentive…like a new space race…
