Oxia Planum map flyover

A team of European scientists have published the most detailed geologic map of Oxia Planum – the landing site for ESA’s Rosalind Franklin rover on Mars. This thorough look at the geography and geological history of the area will help the rover scout the once water-rich terrain, in the search for signs of past and present life.

Data came from the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter and several instruments on NASA’s Mars Reconnaissance Orbiter (MRO), including the HiRISE camera, which returns images from Mars orbit at 25 cm per pixel.

The mapping leads then pieced together the information on all the areas to form a coherent map that shows the geology of the landing site in unprecedented detail. The map includes the main types of bedrock, and structures with distinct shapes like ridges and craters. It even features the material that rests on top, for example blown by the wind, or thrown long distances when meteorites impacted the surface.
