LCROSS (Lunar CRater Observation and Sensing Satellite) is about to hit the moon. The exact time of the impact (give or take a few seconds) is Friday 9th Oct 2009 11:31:30 UTC (about 7.30 EDT). Its going to hit at about 9000km/hr (~2.5km/s), and with a mass of about 2 tons that will give it about the same energy as a ton of TNT. Its not quite the biggest extra-terrestrial manmade silent bangs ever. Deep Impact which hit comet Temple had a considerably smaller impactor (~400kg) but went MUCH faster (MV^2 counts!). Deep Impact hit the comet at about 10 km/s and had the same energy as about 5 tons of TNT. The weather of late has been lousy in upstate NY, but if its clear, I will try to record the impact. http://blogs.discovermagazine.com/badastronomy/2009/09/14/lcross-impact-site-picked/ This latter site is *GREAT* http://lcross.arc.nasa.gov/observation/amateur.htm All the sky animations were done with Celestia. Its free, and fantastic! http://www.shatters.net/celestia/
