Investigation and proposal of future Mars landing sites • Investigate sites of new scientific interest revealed in data from the HRSC camera, other Mars Express instruments, and current NASA missions for potential future landings • Consider suitability and variety of targets at the sites in relation to expected science instrument package • Evaluate sites in relation to expected lander engineering constraints • landing ellipse, solar power, atmospheric braking, surface winds, slopes, rock abundance, hazards
Study the landing site of the Spirit Mars Exploration Rover in Gusev crater • 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' now under close study by the Spirit rover
Fluidised impact ejecta • use HRSC DTMs to study fluidised ejecta flows at small scales • evaluate volumes, slopes, thicknesses, collapse and alteration • relate to local surface processes SAI 5235: d=28 km 49.35N 241.08W MOLA data
Crater counting from DTMs • apply Hough transform technique for automatic crater recognition to HRSC DTMs • assess usefulness in crater counting for surface age measurements Viking MOLA Hough transform
