Selection and Characteristics of the Dragonfly Landing Site near Selk Crater, Titan

Abstract The factors contributing to the initial selection of a dune site near Selk impact structure on Titan as first landing for Dragonfly mission are described. These include arrival geometry and aerodynamic/aerothermodynamic considerations, illumination, Earth visibility, well likely presence exposed deposits water-rich material, potentially including materials where molten ice has interacted with organics. Cassini observations summarized interpreted: near-infrared reflectance microwave emission data indicate in around crater. Radar topography shows rim have slopes multi-km scales reaching only ?2° degrees, an order magnitude shallower than early photoclinometric estimates.
