On 29 November and 14 December 2005 the High-Resolution Stereo Camera (HRSC), onboard the ESA spacecraft Mars Express obtained image data with a ground resolution of approximately 15 meters per pixel. The data were acquired in the region of Noachis Terra at approximately 50° southern latitude and 2° eastern longitude.
The Maunder Crater, located halfway between Argyre Planitia and Hellas Planitia on the southern Highlands of Mars, has a diameter of 90 kilometers and a current depth of barely 900 meters. In the east, the crater floor is bounded by an approximately 700 meters deep trough. It may be associated with the landslide on the western edge of the crater. Some gullies formed on the upper edge of the through - possible evidence for water seepage. Eye-catching are small (500 to 2500 Meters) dark features on the impact crater floor. These features are Barchan dunes, one of the most abundant dune forms in arid environment. One can find dunes of this kind on earth e.g. in the West-African Namib desert.
