(Nov. 13) -- It's official: There's water on the moon.
NASA's LCROSS probe discovered beds of water ice at the lunar south pole when it impacted the moon last month, mission scientists announced today.

"Indeed, yes, we found water. And we didn't find just a little bit, we found a significant amount," Anthony Colaprete, LCROSS project scientist and principal investigator from NASA's Ames Research Center at Moffett Field, Calif.
The LCROSS probe impacted the lunar south pole at a crater called Cabeus on Oct. 9. The $79 million spacecraft, preceded by its Centaur rocket stage, hit the lunar surface in an effort to create a debris plume that could be analyzed by scientists for signs of water ice.
Scientists have suspected that permanently shadowed craters at the south pole of the moon could be cold enough to sustain water frozen at the surface. Water has already been detected on the moon by a NASA-built instrument on board India's now defunct Chandrayaan-1 probe and other spacecraft, though it was in very small amounts and bound to the dirt and dust of the lunar surface.

NASA plans to return astronauts to the moon by 2020 for extended missions on the lunar surface. Finding usable amounts of ice on the moon would be a boon for that effort since it could be a vital local resource to support a lunar base.
The impact was observed by LCROSS's sister spacecraft, the Lunar Reconnaissance Orbiter, as well as other space and ground-based telescopes.
The debris plume from the impacts was not seen right away and was only revealed a week after the impact, when mission scientist had had time to comb through the probe's data.
NASA launched LCROSS — short for Lunar Crater Observation and Sensing Satellite — and LRO in June.
just saying.
