This HiRISE image shows "Victoria Crater," an impact crater at Meridiani Planum, near the equator of Mars. The crater is approximately 800 meters (about half a mile) in diameter. It has a distinctive "scalloped" shape to its rim, caused by erosion and downhill movement of crater wall material. Layered sedimentary rocks are exposed along the inner wall of the crater, and boulders that have fallen from the crater wall are visible on the crater floor. The floor of the crater is occupied by a striking field of sand dunes.
Since January, 2004, the Mars Exploration Rover Opportunity has been operating at Meridiani Planum. Five days before this image was taken, Opportunity arrived at the rim of Victoria Crater, after a drive of more than 9 km (over 5 miles). The rover can be seen in this image, at roughly the "ten o'clock" position along the rim of the crater.

Image TRA_000873_1780 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on October 3, 2006. Shown here is a portion of the complete image. The complete image is centered at -2.1 degrees latitude, 354.5 degrees East longitude. The range to the target site was 269 km (168 miles). At this distance the image scale is 27 cm/pixel (with 1 x 1 binning) so objects ~81 cm across are resolved. The images shown on this page been map-projected to 25 cm/pixel and north is up. The image was taken at a local Mars time of 3:28 PM and the scene is illuminated from the west with a solar incidence angle of 56.2 degrees, thus the sun was about 33.8 degrees above the horizon. At a solar longitude of 115.3 degrees, the season on Mars is Northern Summer.
