It’s a Web browser-based mapping tool which provides up-and-close view of the Mars with the click of a mouse. These maps were made from the images taken by NASA's orbiting Mars Global Surveyor and Mars Odyssey.
Although, the map doesn't show the total surface of Mars but one can see a strip after using the slider to zoom out. It doesn't provide driving directions, but visitors can see the red planet in three different formats. Interesting search results include regions, plains, mountains, canyons, ridges, stories, dunes, craters and spacecraft such as NASA vehicles Mars Pathfinder and Sojourner.
Other planets in the mapping list are Mercury, Venus, Jupiter, Saturn, Uranus, Neptune and Pluto. In future these planets would be mapped by Google.
