Since Google Mars maps and moon one came out, and as Google had already been in collaboration with NASA, it was no wonder it was only a matter of time and the Google Earth will not be a valid name anymore. Google Earth already launches with top view of earth. And while Microsoft is still struggling to get people to use it’s own clone of it, Google Earth now allows you to fly away into space with Google Sky. Just download the latest version of Google earth and you are out there on your own. Enjoy the video on the same page also while downloading.
