There’s just no way space mining makes money with current tech.
AstroForge thinks they can make asteroid mining work with existing technology. Their CEO did a podcast with Payload a few weeks ago (link, but it’s also on Spotify and elsewhere).
They have a demo sat testing their forge and will launch a 2nd sat later this year to do an asteroid flyby. They think they can launch 20+ satellites on a Falcon 9 that could each return $100 million in platinum to the Earth.
Resource extraction on earth is super dirty and exploitative, so I’m all for automating it and moving it to space as soon as it’s commercially viable.
