INVESTIGATION OF THE MARS EXPLORATION ROVER GUSEV LANDING SITE USING THE MARS EXPRESS HRSC CAMERA G. Michael (1), R. Jaumann (1), E. Hauber (1), H. Hoffmann (1), F. Scholten (1), K. Gwinner (1), B. Foing (2), T. Zegers (2), R. Greeley (3), G. Neukum (4), and the HRSC Co-Investigator Team (1) Institute of Planetary Research, German Aerospace Center (DLR), Berlin, (2) European Space Agency (ESA-ESTEC), Noordwijk, (3) Dept. of Geological Sciences, Arizona State University (4) Institute of Geosciences, FU Berlin We intend to use the data from the Mars Express HRSC camera to study the landing site of the Spirit Mars Exploration Rover in Gusev crater. HRSC (High Resolution Stereo Camera) records images at up to 10m resolution at nadir, with three colour, one IR, and four stereo/photometry channels. It is operating on board the Mars Express spacecraft, in orbit at Mars since December 2003. The instrument offers broad coverage of the study region at high resolution, in colour, with multiple viewing angles for stereo processing. To date, HRSC has made 3 imaging passes over Gusev, in orbits 24, 72, and 283, providing north-south swaths of order 50 km in width We expect to produce digital elevation models of up to 50m horizontal resolution for investigation in combination with the colour mosaics. Our interest will be focused on the possible ancient presence of water in the crater, and also on the origin and geological history of the ’Columbia Hills’ soon to come under close study by the Spirit rover. 1
