Description
This image taken by the Mars Exploration Rover Spirit microscopic imager, an instrument located on the rover's instrument deployment device, or arm, shows a patch of soil at the target nicknamed "Squiggle Dunes." The rover imaged this area, which measures 3 centimeters (1.2 inches) across, just before it drove 24.4 meters (80.1 feet) on the 39th sol of its journey.
