Moon crash

NASA crashed two spacecraft into the surface of the moon in the search of water on the Earth's natural satellite.A 5,000-pound part of the Lunar Crater Observing and Sensing Satellite was aimed at the moon's south pole. The impact is to form a huge plume of debris above the moon through which another part of the satellite will be sent, using sensors to search for signs of water.

The second section hit the moon about 4 minutes after the first, creating its own ejecta field, which instruments on Earth will analyze.
About 10 years ago, NASA found signs of water on the moon. Such a find is considered important should plans for travel to other planets be carried out.

 A United Launch Alliance Atlas V launches at 5:32 PM after a 20 minute weather delay from Complex 41 at the at the Cape Canaveral Air Force Station, Florida on June 18, 2009. The rocket roared into the clouds carrying a double payload, NASA's Lunar Reconnaissance (LRO) and Lunar Crater Observation and Sensing (LCROSS) Satellites. LRO will map the lunar surface in high detail to prepare for future manned missions to the moon. LCROSS will impact into the moon's south pole on October 9, 2009 to conduct studies of its surface.
