Hypanis Vallis is one of four candidate landing sites under consideration for the ExoMars 2018 mission. It lies on an exhumed fluvial fan, thought to be the remnant of an ancient river delta at the end of a major valley network. Distinct layers of fine-grained sedimentary rocks provide access to material deposited about 3.45 billion years ago.
The image combines HRSC images from ESA Mars Express with MOLA topography data from NASA's Mars Global Surveyor. The landing ellipses under evaluation for site selection are indicated, and cover an area of 104 × 19 km. The orientation of the landing ellipse depends on when the launch takes place within a given launch window – the sites have to be compliant with launch opportunities in both 2018 and 2020, as indicated.
