HRSC Press Release #351 - Noctis Labyrinthus (orbit 3155)
]')) Perspective view #1 |
On 25 June 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 3155 with a ground resolution of approximately 16 meters per pixel. The data were acquired in the region of Noctis Labyrinthus at approximately 6.5° southern latitude and 260° eastern longitude. The sun illuminates the scene from the north-west (from top right in the topview images).

The region Noctis Labyrinthus, the ”Labyrinth of the Night” is located directly on the western edge of Valles Marineris, the ”Grand Canyon of Mars”. It is part of the complex graben system which is associated with the up-arching of Tharsis. Eye-catching is the high density of deeply incised, smaller, labyrinth-like fractures.

The scene exhibits parts of those graben structures which are incised up to 5000 meters. They are strongly eroded as can be seen at the bottom of the graben which exhibits detritus. Younger lithologies can be seen on the upper edge of the graben.

Bei den Gräben handelt es sich um Zeugen so genannter Extensionstektonik. Der starke Vulkanismus in der Tharsis Region war mit einer deutlichen Hebung großer Teile des Gebietes verbunden. Durch diese Hebung kam es zu Spannungen, die zur Ausdünnung und Rissbildung in der Kruste führten. In der Übersichtskarte ist deutlich zu erkennen, dass die oberste Kruste teilweise in große Schollen zerbrochen ist.
The fractures are witnesses of so-called extensional tectonics. The intense volcanism in the Tharsis region was associated with an intense up-arching of large areas. This process resulted in tectonic stress, causing the crust to thin out and lead to graben formation. As one can see clearly in the context map, the crust in this area is largely fractured.

The colour scenes have been derived from the three HRSC-colour channels and the nadir channels. The perspective views have been calculated from the digital terrain model derived from the HRSC stereo channels. The anaglyph image was calculated from the nadir channeles and two stereo channels. For the first time an anaglyph mosaic was composed using HRSC Data.

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.
