This 3-D stereo anaglyph image
was taken by the Mars Exploration Rover Spirit front hazard-identification
camera after the rover's first drive on Mars Sunday. Engineers
drove the rover approximately 3 meters (10 feet) from the Columbia
Memorial Station toward the first rock target, seen in the foreground.
The football-sized rock was dubbed Adirondack because of its mountain-shaped
appearance. Scientists plan to use instruments at the end of the
rover's robotic arm to examine the rock and understand how it
formed.
