HRSC Press Release #322 - Deuteronilus Mensae (orbit 1483)
Traces of ice-rich Debris in Deuteronilus Mensae
]')) RGB Colour Image #1 |
On 14 March 2005 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 1483 with a ground resolution of approximately 29 meters per pixel. The data were acquired in the region of Deuteronilus Mensae at approximately 39° northern latitude and 23° eastern longitude. The sun illuminates the scene from the south-west (from bottom left in the image).
]')) Context Map |
One of the most striking features of Mars is the dichotomy between the southern highlands and the up to 3 km lower northern plains. The boundary between these two regions is marked by a transition characterized by an intact highland zone and areas with remnant mesas and isolated eroded knobs. The image scene of Deuteronilus Mensae depicts different stages of highland degradation in this zone. Numerous flow patterns in wide valleys and along ridges and scarps indicate movement of debris material mixed with ice towards the surrounding areas.

Since the discovery of these structures, scientists assume that the mixture of debris and ice genetically resembles rock glaciers which are commonly found in cold-climate areas on the Earth. Like on Earth, these landscapes are climate indicators and it is discussed whether ice could be still present in the pore space of the Martian features and in how far these landforms might still be active today.
]')) Nadir Image #1 |
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 form the nadir channel which provides the highest detail of all channels.
