HRSC Press Release #391 - Mamers Valles (orbit 3304)
]')) Perspective view #1 |
On 5 August 2006 the High-Resolution Stereo Camera (HRSC), under the leadership of the Principal Investigator Prof. Dr. Gerhard Neukum of Freie Universitaet Berlin, onboard the ESA spacecraft Mars Express obtained image data in orbit 3304 with a ground resolution of approximately 14 meters per pixel. The data were acquired in the region of Mamers Valles at approximately 39° northern latitude and 17° eastern longitude.

The image shows a circular, approximately 30 kilometers wide and 1400 meters deep depression southwest of Mamers Valles. Parts of the valley system are visible on the north- eastern corner of the image.
]')) Context Map |
Mamers Valles is a valley winding for approximately 1000 kilometers along the northern lowland and southern highland boundary in the region Deuteronilus Mensae on mars. The region is known as so called ”fretted terrain”, a region characterized by numerous deep and very wide labyrinth like valleys and more or less circular depressions which often exhibit flowing structures on their even floors.

The flow structures (1) are commonly interpreted as ice rich debris flows and show some resemblance to block glaciers known on Earth.
]')) Feature Map |
The sporadic uprisings in the center of the depression could be remnant mountains or blocks of rock which detached from the flanks of the depression and were transported into its center (2).
]')) RGB Colour Image #1 |
The wrinkle ridges (3) on the surrounding highlands are generally associated with cooling lava. The dark colored crater filling (4) could be material which formed in situ or material of unknown origin that was transported by wind.

The colour scenes have been derived from the three HRSC-colour channels and the nadir channel. The perspective views have been calculated from the digital terrain model derived from the stereo channels. The anaglyph image was calculated from the nadir and one stereo channel. The black and white images were derived from the nadir channel which provides the highest detail of all channels.

The High Resolution Stereo Camera (HRSC) experiment on the ESA Mars Express Mission is led by the Principal Investigator (PI) Prof. Dr. Gerhard Neukum who also designed the camera technically. The science team of the experiment consists of 40 Co-Investigators from 33 institutions and 10 nations. The camera was developed at the German Aerospace Center (DLR) under the leadership of the PI G. Neukum and built in cooperation with industrial partners (EADS Astrium, Lewicki Microelectronic GmbH and Jena-Optronik GmbH). The experiment on Mars Express is operated by the DLR Institute of Planetary Research, through ESA/ESOC. The systematic processing of the HRSC image data is carried out at DLR. The scenes shown here were created by the PI-group at the Institute for Geological Sciences of the Freie Universitaet Berlin in cooperation with the German Aerospace Center (DLR), Institute of Planetary Research, Berlin.
