NASA's Mars Rover Opportunity captured this image looking eastward over the Endeavour Crater late in the afternoon of Opportunity's 2,888th Martian sol (day) which corresponded with March 9, 2012 here on Earth. In the foreground, Opportunity's own shadow appears, in a sort of one-step-removed self-portrait. The Endeavour Crater where Opportunity spent the winter months spans 14 miles in diameter, roughly the same area as Seattle. The image is a mosaic of about a dozen images and presented in false color to draw out certain features of the topography.
