Got enough of Google Earth? Try Google Mars
In collaboration with NASA researchers at Arizona State University, Google has created what they declared to be ?the most detailed scientific maps of Mars ever made?.
At the moment this map is available at www.google.com/mars , but soon it should become an extra feature on Google Earth.
While browsing around Mars, you can choose how you want to visualize the map in elevation, infrared or visible. You can also click on links that will take you to specific areas of the so-called red planet and see its several mountains, dunes, canyons and craters.
