The Lunar Crater Observation and Sensing Satellite (LCROSS) will crash into the moon on Friday morning, destroying itself in search of water in the form of ice on the surface of the moon. Four minutes after the Centaur upper stage rocket will hit the Cabeus A crater at 7:30 a.m. on Oct. 9, the Shepherding Spacecraft will make impact. The Centaur will create a plume possibly containing ice that may be visible to some areas on Earth. By traveling through the plume, the Shepherding Spacecraft will be able to analyze the material that was sent flying off of the moon.
