Paul Spudis discusses the LCROSS water results and how it correlates with measurements made by other spacecraft: A Rainbow on the Moon - The Once and Future Moon/Air & Space Mag.

For a very brief time, a rainbow might have been visible to an observer standing on the lunar surface. And like its namesake, this rainbow is a promise – a promise that the Moon is habitable. It is an invitation to humanity to extend man’s domain to our nearest planetary neighbor.

John Bossard points me to a posting of his in June that included a LRO/LCROSS Launch Update presentation (pdf) given by Todd May, NASA manager of the Lunar Precursor Robotic Program. The slides provide a nice overview of the two spacecraft and it is interesting to compare the expectations for LCROSS with what actually happened.

Ray at Space Prizes provides some LCROSS related links plus some discussion of how the LCROSS results might affect space policy, lead to new lunar contests, etc.: Lunar Water - Space Prizes.
