Lunar Crater Observation and Sensing Satellite

The Lunar Crater Observation and Sensing Satellite (LCROSS) was a space mission launched by NASA to study the Moon's surface, especially its water content. It consisted of a main satellite and a spent rocket stage, which intentionally crashed into a lunar crater known to contain ice. The impact generated a plume of debris, which the satellite observed with sensors to detect water and other materials. This helped scientists confirm the presence of water ice in lunar craters, providing valuable information for future exploration and potential lunar resource utilization.
