HRSC Press Release #223 - Ausonia Mensa (orbit 0506)
Remnant Massif Ausonia Mensa
On 13 June 2004 the High-Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express obtained image data in orbit 506 with a ground resolution of approximately 37.6 metres per pixel. The data were acquired in the region of Hesperia Planum, at approximately 30.3° southern latitude and 97.8° eastern longitude.
RGB Farbbild #1
The image shows a large remnant mountain with several impact craters, rising above basaltic sheet layers. The mountain stretches over an area of approximately 98 kilometres by 48 kilometres and has an elevation of 3700 meters. A large crater, approximately 7.5 kilometres in diameter and 870 meters deep was partially filled with sediment. The northern flank of the crater is disturbed by a large erosion gully. Numerous branched channels, a result of erosion, run along the edge on top of the plateau toward the plains at the bottom of the mountain.
The western flank of the mountain is dominated by a large crater of approximately 6 kilometers in diameter which clearly shows an ejecta blanket and secondary cratering. Aeolian structures are visible about 50 kilometers southeast of the massif, indicating channeling of atmospheric flow. They are clearly visible because of their different color. A strongly eroded, partly filled crater of approximately 6 kilometers in diameter is visible north of the massif. The crater is characterized by numerous, smaller craters of younger age.
Die Farbansichten wurden aus dem senkrecht blickenden Nadirkanal und den Farbkanälen erstellt, die Schrägansicht wurde aus den Stereokanälen der HRSC berechnet. Die Anaglyphen werden aus dem Nadirkanal und einem Stereokanal abgeleitet. Die schwarzweißen Detailaufnahmen wurden dem Nadirkanal entnommen, der von allen Kanälen die höchste Auflösung zur Verfügung stellt.
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.
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.
