HRSC Press Release #203 - Olympus Mons Ost (orbit 1089)
Image Footprint |
Eastern scarp of Olympus Mons
Die hochauflösende Stereokamera (HRSC) auf der ESA-Sonde Mars Express nahm am 23. November 2004 im Orbit 1089 die östliche Steilkante des Vulkans Olympus Mons mit einer Auflösung von etwa 11 Metern pro Bildpunkt auf.
Die Abbildungen zeigen hiervon einen Ausschnitt, dessen Bildmitte sich bei 17,5 Grad südlicher Breite und 230,5 Grad östlicher Länge befindet. An manchen Stellen ist die Geländekanten bis zu sechs Kilometer hoch.

These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the eastern scarp of the Olympus Mons volcano on Mars.

The surface of the summit plateau's eastern flank shows lava flows, which have a length of several kilometres and a width of a few hundred metres. Age determinations show that they are up to 200 million years old, in some places even older, indicating episodic geologic activity.

The lowland plains, seen here in the eastern part of the image (bottom), typically have a smooth surface. Several channel-like features are visible which form a broad network composed of anastomosing and intersecting channels that are several kilometres long and up to 40 m deep. Several incisions suggest a tectonic control; others show streamlined islands and terraced walls suggesting outflow activity. Age determinations show that the network-bearing area was geologically active as recent as 30 million years ago.
Perspective view #1 |
Between the edge of the lowland plains and the bottom of the volcano slope, there are 'wrinkle ridges' which are interpreted as the result of compressional deformation. In some places, wrinkle ridges border the arch-like terraces at the foot of the volcano slope.

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.
