Google Earth 5.0
Google Earth 5.0, the newest versions has so many more features than any other previous versions! New features include, a much more detailed view of the ocean floor, a feature that you can see the stars, you can also see the planet Mars in 3-D! Google Earth now has a historical feature where you can zoom in on a place and see what that place looks like now as well as back in the past. One of the best, and most fun features is the flight simulator! That's right, you can physically fly over the earth, being controlled by your arrow keys or joystick. Just do not crash or you will have to start over! :) http://googleblog.blogspot.com/2009/02/dive-into-new-google-earth.html
