Google has released the beta version of Google Earth to existing users of Keyhole, the mapping software that they bought last year which is also the basis for the satellite imagery in Google Maps. This article also has some screenshots, and here are some screenshots at Flickr. Between the reviews and the screenshots, it sounds and looks like this will be very cool, hopefully a lot nicer than the already cool Worldwind software that NASA offers. Now we just have to wait for a release to the general public. I want it now… 😉
