Caption:

Image PSP_001364_2160 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on November 10, 2006. The complete image is centered at 35.9 degrees latitude, 274.9 degrees East longitude. The range to the target site was 287.8 km (179.9 miles). At this distance the image scale is 57.6 cm/pixel (with 2 x 2 binning) so objects ~173 cm across are resolved. The image shown here has been map-projected to 50 cm/pixel and north is up. The image was taken at a local Mars time of 3:22 PM and the scene is illuminated from the west with a solar incidence angle of 48 degrees, thus the sun was about 42 degrees above the horizon. At a solar longitude of 133.5 degrees, the season on Mars is Northern Summer.
