NASA's Mars Exploration Rover Opportunity captured this view of its afternoon shadow stretching into Endeavour Crater during the 3,051st Martian day, or sol, of Opportunity's work on Mars (Aug. 23, 2012).
The rover was perched on the western rim of the crater, which is 14 miles (22 kilometers) in diameter.
Opportunity's front hazard-avoidance camera took this image. The camera has a fisheye lens; the image has been processed to straighten the horizon. This view echoes one of the most popular images of Opportunity's long-lived mission, a shadow self-portrait (http://photojournal.jpl.nasa.gov/catalog/PIA06739) taken at Endurance Crater about eight years earlier.
