This stereo view from the navigation camera on NASA's Mars Exploration Rover Opportunity shows a vista across Endeavour Crater, with the rover's own shadow in the foreground. The view spans 216 compass degrees, from north at the left to south-southwest on the right. It appears three-dimensional when seen through blue-red glasses with the red lens on the left.
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). Figure 1 and Figure 2 are the separate left-eye and right-eye mosaics that are combined into the stereo view.
