Google has launched Google Mars which allows you to pan and zoom around the red planet's surface. It gives you three different views: visible, color-coded elevation, and infrared. There's also a bunch of markers for locating landmarks (including the legendary "face" and the less well-known Happy Face Crater) and landing sites. Google Mars and the mars-themed logo at Google.com commemorate the 1855 birth of astronomer Percival Lowell.
