NASA's LCROSS Mission Proves Lunar Ice Suspicions

NASA is reporting that preliminary data from the LCROSS mission indicates that there really is water in one of the permanently shadowed lunar craters, just as they suspected back in September. "'We are ecstatic,' said Anthony Colaprete, LCROSS project scientist and principal investigator at NASA's Ames Research Center in Moffett Field, Calif. 'Multiple lines of evidence show water was present in both the high angle vapor plume and the ejecta curtain created by the LCROSS Centaur impact. The concentration and distribution of water and other substances requires further analysis, but it is safe to say Cabeus holds water.'"
