The Mars rover Opportunity caught this image of its own silhouette.
NASA’s Mars Exploration Rover Opportunity took this image of its own shadow, looking eastward shortly before sunset on the 3,609th Martian day, or sol, of Opportunity’s work on Mars (March 20, 2014).
The rover’s shadow falls across a slope called the McClure-Beverlin Escarpment on the western rim of Endeavour Crater, where Opportunity is investigating rock layers for evidence about ancient environments. The scene includes a glimpse into the distance across the 14-mile-wide (22-kilometer-wide) crater.
Brightest Mars in 6 years! April 2014 is the best time to see Mars.
