Lunar smackdown set for Friday
Posted in Current Events, Pop Astronomy on October 7th, 2009 by Peter LipscombOn Friday morning October 9th, two spacecraft will crash into the Moon. The target is crater Cabeus near the south pole. The collisions are part of the Lunar Crater Observation and Sensing Satellite (LCROSS) mission. The planned outcome of this lunar smackdown will allow scientists to confirm if water ice lies hidden within permanently shadowed craters.
Following the Apollo missions, interest in returning to the Moon became a low priority. But that all changed in 1999 when NASA’s Lunar Prospector detected the presence of hydrogen in the lunar polar regions. Most recently, the Cassini and Deep Impact probes along with India’s Chandrayaan-1 lunar orbiter obtained compelling evidence that the hydrogen may exist as water ice near the Moon’s poles.
