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 during the 1,820th to 1,822nd Martian days, or sols, of
Opportunity's surface mission (March 7 to 9, 2009).
This view is presented as a vertical projection with geometric seam
correction. North is at the top.
The rover had driven 20.6 meters toward the northwest on Sol 1820 before
beginning to take the frames in this view. Tracks from that drive recede
southwestward. For scale, the distance between the parallel wheel tracks
is about 1 meter (about 40 inches).
The terrain in this portion of Mars' Meridiani Planum region includes
dark-toned sand ripples and small exposures of lighter-toned bedrock.
