If you are going to throw rocks at the Moon, you should try doing it NASA style. There is just over a week to go before the LCROSS (Lunar CRater Observation Sensing Satellite) mission sends the Centaur Upper stage rocket crashing into the Moon, creating a 10km plume near the Moon’s southern pole.  If you have a 10″ or bigger scope you might even get to see it….   Four minutes later the sheparding spacecraft does a flyby through the debris, and sends data back to earth before it too slams into the moon.

If there is water, we should know fairly quickly and hopefully get some indication of how much.  That is really the question. How much are we likely to find.  Only 9 days to impact!
