Google Mars

In collaboration with NASA researchers at Arizona State University, Google has created some of the most detailed scientific maps of Mars ever made.

There are three different types of data in Google Mars:

  • 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.

Mars in Google Earth allows you to fly to the red planet in a virtual 3D environment. Check it out! ...
