The navigation camera on NASA's Mars Exploration Rover Opportunity took images during the rover's 285th martian day (Nov. 11, 2004) that are combined into this 360-degree panorama. Opportunity had reached the base of "Burns Cliff," a portion of the inner wall of "Endurance Crater." This view shows rock layers in the wall. The rover's position when taking the images was labeled Opportunity site 37, position 550. This view is presented in a polar projection with geometric seam correction.
