New discoveries of significant amounts of water (at least six-feet of water ice in each of forty craters) on what was long considered a bone-dry Luna show why today’s AGW to-do hardly can be considered “settled”:
“If you converted those craters’ water into rocket fuel, you’d have enough fuel to launch the equivalent of one space shuttle per day for more than 2000 years. But our observations are just a part of an even more tantalizing story about what’s going on up on the Moon.”

I enjoyed this 1992 scifi novel of physicist Charles Sheffield’s, though it seemed unnecessarily complicated in the beginning. A little more action before establishing the seven main characters would have prevented me from putting it down so often. Sheffield died of brain cancer in 2002, which resonates because a good friend of Mrs. Charm’s is struggling with it. Seems to have it licked for the moment, though the odds of that lasting are very low.
I bring up Sheffield to point out how easy it is to fall into these stories of ordinary life in the solar system, as if we had gotten off the engineering dime and were actually living in/on Luna, Mars, and the Asteroid Belt. A lot of Cold As Ice occurs on (actually, under the surface of) Ganymede, which recalls Heinlein’s impossible young adult novel, Farmer In The Sky, which Mr. B. and I started as a bedtime story but never finished.
We had the space probe pictures and details of Jupiter’s radiation to consult, as Heinlein did not. Also life on (under, actually) Europa, which seems plausible, despite Sheffield’s scientific realism of the dangers of Jovian radiation. I hope all this verisimilitude means humanity really will do these things and not just wallow forever in political corruption and the threat of war. But a posed result of the latter is limned chillingly in Cold As Ice as one of the spurs for continued colonization.

We’ve heard several times that there may be water on Luna. In the form of ice on the surface, and, perhaps, some liquid underground. NASA is expected to unveil Thursday research showing "a lot of water" exists on the surface.
From the AAAS journal Science advancer to Science writers: "…three reports utilize data collected by three separate spacecrafts to provide evidence of hydroxyl (OH) or water – or both – on the surface of the Moon. These findings are forcing a reexamination of the notion that our Moon is completely dry."
If there is abundant water, it makes a colony more feasible, as well as the refueling of spacecraft for interplanetary travel. As it says here I’m ready to believe. Just show me the water.
UPDATE: Here’s the NASA version. Suspiciously timely, given recent cancellation of back-to-the-moon? Naw.

Presume this is a railgun or a mass driver for flinging spacecraft into orbit. Bet it would be awfully cold on your bottom sitting on luna’s rock and dust like these folks are doing. They probably live underground to escape Sol’s radiation. Still, it would be fun to go. It is, actually, in the imagination.
