The HiRISE camera aboard Mars Reconnaissance Orbiter captured this oblique view of Victoria crater on 18 July 2009. Ordinarily, Mars Reconnaissance Orbiter's instruments are pointed straight downward, but to capture this view it looked 22 degrees away from nadir, toward the east. (East is to the top in this image.) The unusually oblique view allowed HiRISE to photograph the west-facing cliffs of the scalloped capes surrounding the crater. This is a crop from HiRISE's original view. The Mars Exploration Rover Opportunity spent more than a Mars year exploring Victoria crater, from September 2006 through August 2008, partially circumnavigating it before entering it briefly to examine the steep cliffs up close. Opportunity's tracks are visible as slightly lighter-colored, reddish-toned straight lines on the left side of the image, punctuated by dots, marking the spots where Opportunity turned in place.
