Image TRA_000828_1805 (here broken in 4 sub-images) was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard the Mars Reconnaissance Orbiter spacecraft on September 30, 2006. The full image is centered at 0,5° North Latitude and 142,1° East Longitude.
The images are oriented such that North is towards the top. The range to the target site was 270 Km (about 169 miles). At this distance the image scale is 27 cm/pixel (with 1 x 1 binning) so objects ~81 cm across are resolved. The image was taken at a local Mars time of 03:27 PM and the scene is illuminated from the west with a solar incidence angle of 55,2°, thus the Sun was about 34,8° above the horizon.
At a Solar Longitude of 113,6° the season on Mars is Northern Summer.
