Google has shown us satellite imagery from Earth and even the Moon, but now it appears Google is offering maps of other planets, in this case Mars. Visit Google Mars and you will see a colorful crater filled surface (as shown below).
Googling Google details the mapping features of Google Mars and the Googlist also reported that Google has also registered a number of other planet related domains like GoogleMercury.com, GoogleVenus.com and so on. So it appears Google has plans to show additional planets as NASA produces the imagery to display.
UPDATE: Google has made a post in reference to Google Mars on the Google Blog.
