NASA's Mars Exploration Rover Opportunity used its navigation camera to record this vista looking eastward across Endeavour Crater, with the rover's own shadow in the foreground.
Opportunity has been studying the western rim of Endeavour Crater since arriving there in August 2011. The crater spans 14 miles (22 kilometers) in diameter, by far the largest that Opportunity has visited since it landed on Mars in January 2004.
The component images in this mosaic view were taken during the 3,020th Martian day, or sol, of Opportunity's work on Mars (July 22, 2012).
