NASA's Mars Exploration Rover Opportunity used its navigation camera to
take the images combined into this full-circle view of the rover's
surroundings just after driving 111 meters (364 feet) on the 1,797th
Martian day, or sol, of Opportunity's surface mission (Feb. 12, 2009).
North is at the center; south at both ends.
Tracks from the drive recede northward across dark-toned sand ripples in
the Meridiani Planum region of Mars. Patches of lighter-toned bedrock are
visible on the left and right sides of the image. For scale, the distance
between the parallel wheel tracks is about 1 meter (about 40 inches).
This view is presented as a cylindrical projection with geometric seam
correction.
