You still have to get the materials for your experiments up there. In the case of nuclear-powered engines, that isn't trivial (unless you mine them off world).

- JoeAltmaier 6y agoWhich is why, space mining will likely never benefit Earth. Any material 'up there' is so much more valuable in space than dropping it down to Earth to make Coke cans or whatever.
- nix23 6y agoNot earth but belters ;)
- 2StepsOutOfLine 6y agoI, for one, will keep a fish tank on earth in case any better descendents swing by to visit.
- nix23 6y agoYesyes...family-meal is a bit more complicated that normal, but my surprise gifts are massive ice-cubes.
- scruple 6y agoAssuming we don't see corporate space sponsorship.
- JoeAltmaier 6y agoYes I can imagine Earth financial markets will speculate in space-based industry. Grounders may become 'wealthy' from off-world activities, but without ever actually benefitting from them directly.
- Symmetry 6y agoWell, things like much larger dishes on comsats could benefit Earth quite a bit.
- papito 6y agoWell, usually. If we dragged in Psyche 16 into our neighborhood, it would make all gold here worthless. A NASA probe is already en route.
- JoeAltmaier 6y agoBut how to get the gold down to the ground? And why? Its far more useful up in space. Would Earth ever see even another gram of that gold?
- dividedbyzero 6y agoI imagine the amount of stuff floating around up there is so vast, once you can build all the heavy, bulky parts of a propulsion system in space, produce fuel in space, and automate the mining, you could truck absurd amounts of all kinds of raw materials to Earth, easily more than you could realistically use in orbit short-term. But I guess people could be made to pay a pretty penny for Space Gold accessories – or space diamond, space platin, space whatever. Say, an Apple Watch milled from a solid chunk of Space Platin or even Space Diamond, I think that might sell pretty well. As to getting the stuff down, I imagine one could do that relatively low-tech; cut it into manageable chunks, wrap those in some kind of simple heat shielding, deorbit to some remote place and have some kind of parachute system slow it down enough to not disintegrate on impact; a chunk of solid gold should be able to take quite a beating.
- LargoLasskhyfv 6y agoHave it mined optically in space and then molded/vacuum deposited/3-d printed up there into (passive) lifting bodies of appropriate proportions out of comb like structures, put a jetpack for steering onto it which brings it down into the atmosphere in a controlled way, detach that (reusable) jetpack before burning up, reroute to some orbiting space dock for refueling. Meanwhile, have a massive golden glider splashing down into the ocean somewhere near a cost, and have it towed by tug-boats towards the smelters, forges, metal works, catalyst producers, whatever...
- catalogia 6y ago> But how to get the gold down to the ground? I'm just spitballing here but.. crash it into the moon, mine it there, then use a mass driver to throw small pieces of it to earth?
- abecedarius 6y agoThere are designs to couple the dropping of one thing to the lifting of another, like an elevator (though not necessarily at the same time). This makes delivering payloads to Earth necessary for your launch system. They might as well be valuable payloads. Look up "rotating skyhooks" for one such scheme.
