Google launches Google Moon today. As Google says, it is just one week project suggested by Chikai, a google earth engineer a week earlier.
From the FAQ: 'One small step for Google... On July 20, 1969, man first landed on the Moon. A few decades later, we're pleased to cut you in on the action. Google Moon is an extension of Google Maps and Google Earth that, courtesy of NASA imagery (thanks, guys!), enables you to surf the Moon's surface and check out the exact spots that the Apollo astronauts made their landings.'
