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 1,818th Martian day, or sol, of Opportunity's
surface mission (March 5, 2009). South is at the center; north at both
ends.
This view is presented as a polar projection with geometric seam
correction. North is at the top.
The rover had driven 80.3 meters (263 feet) southward earlier on that sol.
Tracks from the drive recede northward in this view.
The terrain in this portion of Mars' Meridiani Planum region includes
dark-toned sand ripples and lighter-toned bedrock.
