By now everyone knows about Google Earth, probably the best free software of the last decade.
Well just in time for the 40th anniversay of the Moon landings, Google Earth brings you THE MOON! Use Google Earth 5 to see:
* Tours of lunar landing sites, narrated by Apollo astronauts
* 3D models of rovers and landers
* 360-degree photo panoramas
* Rare TV footage of the Apollo missions

Hey, did I mention that Google Earth does a 3D version of Planet Mars as well? So if you always wanted to fly over the area where the Viking spacecraft landed in 1976... now you can!
It gets even better. You can use Google Earth as a planetarium right inside your computer! You can take a trip through the heavens, scan for planets, check out current events, and so on. Engage!
