Volcanic landforms on Mars as seen in the first HRSC images — •Ernst Hauber1, Gerhard Neukum2, Ralf Jaumann1, and The HRSC Co-Investigator Team2 — 1DLR-Institut für Planetenforschung, Rutherfordstr. 2, D-12489 Berlin — 2Institut für Geologische Wissenschaften, FU Berlin, Malteserstr. 74-100, D-12249 Berlin
Volcanic landforms are among the most widespread and diverse surface features on Mars. Volcanic processes operated through the entire evolution of the planet up to very recent times. Recent remote sensing experiments have revealed important new aspects of Martian volcanology.
The ESA Mars Express mission carries the High Resolution Stereo Camera (HRSC) that will provide 3D colour imagery. Additionally, a separate channel with a narrow-angle optics (the Super Resolution Channel, SRC) will take images with a spatial resolution of 2-3 m/pixel, which will be embedded in the HRSC images (10-12 m/pixel). Thus, the SRC images will be interpreted within the geological context provided by 3D colour HRSC images. Such imagery is particularly valuable for the investigation of volcanic features like lava flows, small shields, calderas, pit craters, etc.
The camera will begin to collect images immediately after the spacecraft has reached its final mapping orbit in mid-January, 2004. Major volcanic constructs that will be covered early in the mission (January and February) include the giant shields of Olympus Mons and Ascraeus Mons. We will report on our preliminary investigations of HRSC/SRC imagery of volcanic features on Mars.
