On Friday morning, an unmanned spacecraft launched in June will crash into the moon's surface. On purpose.
NASA wants to know if the twin impacts of the Lunar Crater Observation and its Sensing Satellite (LCROSS) will reveal any ice or water under the moon's surface. The cosmic collisions are expected to kick up tons of moon dirt in giant debris plumes that will then be scanned for signs of water ice suspected to be buried beneath the floor of a permanently shadowed crater at the lunar south pole. NASA will start broadcasting the event live on NASA TV at 6:30 a.m. EDT (1030 GMT).
More than a few folks are wondering how much the soon-to-be-destroyed LCROSS costs. Answer: $79 million, according to Christian Science Monitor.
