    The Lunar Crater Observation and Sensing Satellite (LCROSS) mission is designed to determine whether water ice is present on the Moon. Water is always an issue for future lunar exploration. LCROSS has two components -? a rocket that will impact a shadowy Moon crater and excavate it, and a satellite that will sample the plume produced by the impact. If ancient ice lies buried on the Moon, it may be ejected and then detected by specialized instruments.
