Google Mars

Google Earth has just gone interstellar - Arizona State University's Mars Space Flight Facility and Google 'teamed up last summer to produce Google Mars,a mapping tool released Monday,which allows users to view and scroll across the surface of the Red Planet,visiting its many landmarks...

The goal here is to bring Mars to the general public, to give them access to a tool that lets them explore Mars in the same way that Google Earth lets you explore the Earth':

The site includes three different presentations of the Martian surface:

* Elevation - A shaded relief map, generated with data from the Mars Orbiter Laser Altimeter (MOLA) on NASA's Mars Global Surveyor spacecraft. This map is color-coded by altitude, so you can use the color key at the lower left to estimate elevations.
* Visible - A mosaic of images taken by the Mars Orbiter Camera (MOC) on NASA's Mars Global Surveyor spacecraft. MOC is like the digital camera you have at home. Basically, this is what your eyes would see if you were in orbit around Mars.
* Infrared - A mosaic of infrared images taken by the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey spacecraft. Warmer areas appear brighter, and colder areas are darker. Clouds and dust in the atmosphere are transparent in the infrared, making this the sharpest global map of Mars that's ever been made.
