Holy crap, the Moon has a ton of water. 25 gallons were kicked up by the probe that impacted it a month ago. This is huge, huge news, because everyone thought that the Moon was as dry as a bone. I see that various studies predicted this recently. A pessimistic article from Space.com from a month ago said “one ton of the top layer of the lunar surface would hold about 32 ounces of water”, but now it’s looking like a lot more.
Now all we need to do is ship nitrogen and other essential nutrients there in huge amounts using mass drivers, a nuclear cannon, or space elevator, put up a few aerogel-insulated domes, and start partyin’! (Well, maybe not exactly, but water does give us huge amounts of oxygen, which we need to breathe, and hydrogen, which can be used as fuel.) This article from LiveScience has more details.
