LCROSS impacts the Moon

October 9, 2009 11:44 by scibuff

Today at 11:31:19.5 UTC the Centaur upper stage impacted the lunar surface a 2.5km/s ejecting about 350 tonnes of lunar material into the path of the Shepherding Spacecraft which impacted about 4 minutes later at 11:35:38.7 UTC, ending thus the flight part of NASA’s LCROSS (Lunar CRater Observation and Sensing Satellite) mission. In the next few weeks, the impact ejecta will analyzed for the presence of hydrated minerals which would tell researchers if water is there or not.
