"MOFFETT FIELD, Calif., Sept. 11 /PRNewswire-USNewswire/ -- NASA has selected a final destination for its Lunar Crater Observation and Sensing Satellite, or LCROSS, after a journey of nearly 5.6 million miles that included several orbits around Earth and the moon. The mission team announced Wednesday that Cabeus A will be the target crater for the LCROSS dual impacts scheduled for 7:30 a.m. EDT on Oct. 9, 2009. The crater was selected after an extensive review as the optimal location for LCROSS' evaluation of whether water ice exists at the lunar south pole.
"LCROSS will search for water ice by sending its spent upper-stage Centaur rocket to impact the permanently shadowed polar crater. The satellite will fly into the plume of dust left by the impact and measure the properties before also colliding with the lunar surface. The LCROSS team selected Cabeus A based on a set of conditions that include proper debris plume illumination for visibility from Earth, a high concentration of hydrogen, and mature crater features such as a flat floor, gentle slopes and the absence of large boulders."
