There was never any reason to spend that kind of money. It was worth going to the moon once to see what was there, but I have yet to see anybody articulate a reason to go back that doesn't rely on soaring rhetoric and implausible money-making schemes.

- Retric 10y agoRare-earth means low concentrations. There is still a lot of this stuff in the darts crust an it's not destroyed with use.
- gozur88 10y agoRare-earth minerals aren't actually rare. The name comes from the relatively low concentrations in which you find them naturally. But we won't run out; they're just more expensive to refine as we tap lower concentration sources. Even poor sources are going to yeild minerals at a cost that's a few orders of magnitude less than a what you'd get on the moon.
