Two New Candidate Landing Sites for the European 2018 ExoMars Mission Near Libya Montes Alluvial Fans, Layered Delta Deposits and Possible Coastal Cliffs

Summary of the proposed Libya Montes landing sites near delta deposits (landing site 1) and near the coastal cliffs of the Arabia contact (landing site 2). Fig. 1: Proposed landing sites at the boundary between the Libya Montes highlands and the smooth plains of the Isidis basin. Landing site ellipses (red) of 10-15 km across are assumed for missions using the MSL heritage landing system. A Morphologic setting for the two landing site ellipses. B Proposed landing site ellipses are located below an elevation of -2600 and -3600 meters and comply with the engeneering constraints that landing site ellipses must be located below +1000 meters. Color-coded HRSC h_2162 DTM on CTX mosaic. C Landing site ellipses mainly cover smooth surfaces with gentle slopes <5o (based on 50m DTM). Slope values are important for the planning of traverses a rover will use to reach sites of scientific interest. Slope values are derived from the HRSC h_2162 DTM. 44th Lunar and Planetary Science Conference (2013) 2378.pdf
