The Lunar CRater Observation and Sensing Satellite (LCROSS) impacted the Moon as planned on 7:31 a.m. (EDT) Oct. 9
The LCROSS experiment consisted of small spacecraft that guided the empty Centaur upper stage from the LRO/LCROSS Atlas 5 launch vehicle into the Moon. The small trailing spacecraft had a set of instruments that photographed and measured the spectral signature of the dust kicked up by the Centaur impact. Numerous Earth-based telescopes attempted to measure the spectral signature of the impact. Results of the experiment should be available over the next few weeks as data are analyzed.
