NASA's Lunar CRater Observation and Sensing Satellite ( LCROSS ) mission was launched in tandem with the Lunar Reconnaisance Observer (LRO) on June 18th this year. LCROSS and LRO are currently in polar orbit of the Moon, together with the Centuar rocket final stage, and LRO is conducting extensive mapping of the lunar surface. The prime aim of the LCROSS mission is to investigate whether water is present, as ice, in permanently shadowed areas near the lunar poles. To achieve that goal, the mission will send the Centaur final stage crashing into a lunar crater near the pole, producing a substantial plume of debris. Those debris will be observed by a Shepherding Spacecraft, which will track behind the Centaur before impacting itself. The crater chosen for the impact is Cabeus, a ~98 km diameter crater that lies within 100 km of the Moon's South Pole. Observations of that crater by LRO, Lunar Prospector and the Chandrayaan-1 and Kaguya spacecraft indicate a strong hydrogen concentration, suggestive of the presence of water ice. Any ice should vaporise when the Centaur impacts, and instruments on board the Shepherding Spacecraft, together with a wide variety of ground- and space-based observatories, including HST, will search for evidence of water. The LCROSS impact is scheduled for Friday October 9th at 7:30 am EDT/ 4:30 am PDT. |
