Space mining
I printed this Space.com article on space mining back in the MSNBC Space board days.
I wonder how far they are along since this 2000 quote; "Space mining is 10 to 20 years, or even further out. However, somebody has to start thinking about these things now."
Probably 20 years out from now if we can get Bush's space plan going in the right direction. If not, who knows when.
Glad to see this 4 year old link is still available.
