The NASA Lunar Crater Observation and Sensing Satellite (LCROSS) sent a Centaur rocket into the Cabeus crater, making a new crater about 18 meters across. Scientists plan to study the debris arc to learn about the chemical makeup of the region, and hope to find traces of water ice. Although there was hope that the debris would be visible through small telescopes from Earth, no such debris was spotted. Scientists have received spectrometer data and are working to decipher it.
