Illuminated by the Sun from the west (right hand side in the image), the pictures are of a ground resolution of approximately 13 meters per pixel. The region, imaged on 26 and 29 March 2007, during Mars Express orbit number 4136 and 4247, is located at approximately 6° South and 145° East.

This colour picture, a mosaic of pictures derived from orbits 4136 and 4147, has been derived from the three HRSC colour channels in combination with the nadir channel.

The region, imaged on 26 and 29 March 2007, during Mars Express orbit number 4136 and 4247, is located at approximately 6° South and 145° East.

The morphology of the terrain, which lies close to the volcanic region of Elysium, is characterised by an extensive transition zone or the so-called ‘global crustal dichotomy boundary’ which separates the southern highlands and northern lowlands. It exhibits clod-shaped or lumpy relief separated by valleys and intermediated graben structures, or elongated, trench-like erosional features.

Deep valleys are incised into the highlands in the northern part of the scene showing linear features on the floor of the valley.

This perspective view was obtained from a Digital Terrain Model derived from the HRSC stereo channels.

Deep valleys are incised into the highlands in the northern part of the scene showing linear features on the floor of the valley. Similar linear features are also seen in the lower part of the picture but the morphology is different from the region in the upper part in that there are no incisions. Also, the area is far less cratered and hence the erosion must be of a relatively recent origin.

Scientists have reason to believe that the valleys might primarily originate from tectonic activity, possibly also modelled locally by subsequent fluid or mass wasting activity.

Aeolis Mensae is located between the border of the northern plains and the southern highlands, indicated by the transition zone. Between the highlands and the plains there is a large average difference in elevation, of about 3000 metres. The origin of this dichotomy is currently a subject of discussion.

This black and white high resolution image was derived from the nadir channel, which provides the highest level of detail. It is a mosaic of pictures derived from orbits 4136 and 4147.

This 3D (anaglyph) image was calculated by putting together data from the nadir channel and one of the stereo channels.
