Caption NASA originale:"Image TRA_000841_1300 was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on October 1, 2006. The complete image is centered at 49,7� South Lat. and 154,2� East Long. The range to the target site was 248,4 Km (such as about 155,3 miles).
At this distance the image scale is 99,4 cm/pixel (with 4 x 4 binning) so objects ~298 cm across are resolved. The image shown here has been map-projected to 100 cm/pixel and North is up. The image was taken at a MLT of 15:39 and the scene is illuminated from the West with a solar incidence angle of 87�, thus the Sun was about 3� above the horizon.
At a Solar Longitude of 114,2�, the season on Mars is Northern Summer".
