LCROSS launched as a secondary payload with Lunar Reconnaissance Orbiter (LRO) on June 18, 2009. After trans-lunar injection, LRO separated and performed its mission.

LCROSS used the Centaur as a 2300 kg kinetic impactor with more than 200 times the energy of the Lunar Prospector (LP) impact to excavate more than 250 metric tons of lunar regolith. The resulting ejecta cloud was observed from a number of Lunar-orbital and Earth-based assets, and th... ...Show More
