A football-field-size crater, informally named "Santa Maria," dominates the scene in this 360-degree, stereo view from NASA's Mars Exploration Rover Opportunity.

Following a 25-meter (82-foot) drive on the 2,451st Martian day, or sol, of the rover's work on Mars (Dec. 16, 2010), Opportunity used its navigation camera to take the frames combined into this mosaic. The view is presented as a vertical projection, with north at the top.

NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Exploration Rover Project for the NASA Science Mission Directorate, Washington.
