Hi Larry

There's lots of water in the Main Belt, even more in the Trojans, and oceans and oceans worth in the EKB. But the NEOs should have quite a few inactive comets. And recently several low activity comets have been spotted in asteroid orbits in the Main Belt.

But, ironically, the Moon is probably parched and that's why I think GB is wrong. You could make decent rockets by using a mix of powdered aluminium and LOX - mixed together it doesn't burn until raised to a quite high ignition temperature. So rockets could be made on the Moon using indigenous materials, but IMHO it's wasted effort. The Moon is a poor choice compared to the NEOs or even Mars's moons. Utilizing them will open up both the Moon and Mars, if we want them - and I'd pick Mars over the Moon for long-term efforts. Mining thorium or tourism may become feasible for the Moon, but any science, like optical/IR/Radio astronomy, that people say "needs" the Moon can be done as well, if not better, in cis-Lunar orbits or the Earth-Sun L-points.
