GOOGLE EARTH 5.0 SHOWCASES IMAGES OF MARS

Google Earth 5.0 is a fun and free way to waste time, and now it’s even better with the updated Mars in Google Earth, a 3D mapping tool that lets astronomy buffs and armchair astronauts roam the Red Planet.
You now can view antique maps of Mars from over a century ago, as well as the latest images from today’s Mars spacecraft. In addition, you can go on virtual flybys with NASA’s Mars Odyssey and Mars Reconnaissance Orbiter, and get guided tours of the planet from Public Radio’s Ira Flatow and Bill Nye, the Science Guy.
For a quick tutorial of the new Mars in Google Earth features, check out this Google overview.

Mars in Google Earth is a lot of fun! (Sorry, no GPS navigation yet for the Red Planet.)
