On the 40th anniversary of the Apollo 11 landing Monday, the Internet search giant released an addition to the popular Google Earth mapping software that includes 3D images of the moon's landscape. Astronomy enthusiasts swiftly downloaded the free software so they could take virtual tours of the lunar surface. But will anyone else care to spend all that time looking at the moon's gray, vapid terrain? Even astronaut Buzz Aldrin, the second person to step onto the moon, described it as a place of 'magnificent desolation.' Google and the National Aeronautics and Space Administration don't think so and have been working since 2005 to showcase images the space agency has been storing. The Google Earth project includes maps of Mars and the constellations. What did Google get for all that work? Part of the pact included allowing Google to build a million-square-foot office within NASA's Research Park at Moffett Field near Google's Silicon Valley campus in Mountain View, Calif. Google's co-founders also were granted rights to land their private planes at the airfield. Moon in Google Earth -- the name Google Moon was taken by the previously available, Web-based version -- packs a ton of information. In addition to the moon surface imagery and digital renderings of NASA landing modules, users can view panoramic photos, historic videos and loads of encyclopedic articles. There are also guided tours and landing site classification by country. The new software offers probably the most complete educational tour of the moon for free with lots of images of gray rocks and dust. 'No life, no motion, no air,' Aldrin said in a recent interview with Space.com. 'It just wasn't a very welcome place at all.'
