HiRISE Image TRA_000856_2500Image TRA_000856_2500 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on October 2, 2006. The complete image is centered at 69.8 degrees latitude, 85.8 degrees East longitude. The range to the target site was 312.1 km (195.1 miles). At this distance the image scale is 31.2 cm/pixel (with 1 x 1 binning) so objects ~94 cm across are resolved. The image shown here has been map-projected to 25 cm/pixel. The image was taken at a local Mars time of 2:59 PM and the scene is illuminated from the west with a solar incidence angle of 54 degrees, thus the sun was about 36 degrees above the horizon. At a solar longitude of 114.7 degrees, the season on Mars is Northern Summer.
