HRSC Press Release #423 - Eumenides Dorsum (orbit 5114)
]')) Perspektive #4 |
On 26 December 2007 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 5114 with a ground resolution of approximately 13 meters per pixel. The data were acquired in the region of Eumenides Dorsum at approximately 2° southern latitude and 206° eastern longitude.

Eumenides Dorsum is a mountain range west of the Tharsis Region and part of the Medusae-Fossae Region, which is most likely made up of volcanic (pyroclastic) ash. The image shows an area covering approximately 12.000 km² which is almost 5 times the size of the German state “Saarland”.

The region exhibits several kilometer long linear structures with interspersed channels. The entire area shows impressive examples for the erosional force of wind on Mars. Although Mars’s atmosphere is rather thin compared to the Earth’s atmosphere – just 0.75% of the mean surface pressure, which corresponds to an altitude of about 35 Kilometers above the surface – it can be very dynamic and plays a major role in shaping the red planet’s landscape over a long period of time.

The region is dominated by so-called “Yardangs” (1) which cover most of the pictured area. Yardangs are features in sedimentary rock originating from the erosional force of wind. The wind is transporting loose material like sand grains and acts like a sand-blast unit. It erodes the soft sedimentary rock along already existing structures like gaps, fault lines or incisions and removes the material. Smaller uprisings in the image center (2) have been grinded as well and exhibit a pyramidal shaped morphology. A preferential direction of these features can develop if the wind direction is always alike. In the area pictured, most of the Yardangs are oriented in a north-south direction.

The rather smooth areas in the image center and at the northern part of the region (3) are most likely made up by harder, more resistant material, probably volcanic in origin. Magmatic rock is usually much harder than sedimentary rock and is less affected by corrasion.

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 high resolution 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.
