Dark Shadows on Mars
Like a tourist waiting for just the right lighting to snap a favorite shot during a stay at the Grand Canyon, NASA’s Mars Exploration Rover Opportunity has used a low sun angle for a memorable view of a large Martian crater.
The resulting view catches a shadow of the rover in the foreground and the giant basin in the distance. Opportunity is perched on the western rim of Endeavour Crater looking eastward. The crater spans about 14 miles (22 kilometers) in diameter. Opportunity has been studying the edge of Endeavour Crater since arriving there in August 2011.
The scene is presented in false color to emphasize differences in materials such as dark dunes on the crater floor. This gives portions of the image an aqua tint.
