Oxia Planum, Mars is the chosen landing site for the European Space Agency’s ExoMars Rosalind Franklin Mission (RFM), expected to launch in 2028 and land in 2030. In preparation for the mission, the landing site has been extensively characterized using orbital spectral, thermal, imaging, and topographic datasets, revealing a complex geological record of aqueous alteration and diverse mineralogical units. Yet important questions remain regarding the site’s stratigraphy, geological evolution, mineralogy, and potential preservation of biosignatures. This session will bring together complementary approaches to understanding Oxia Planum and preparing for its exploration by RFM, including orbital and planned in situ investigations, geological and mineralogical modelling, mission-specific tools and strategies, terrestrial analogues, laboratory studies, and experimental work. We particularly welcome contributions from RFM team scientists and studies addressing geological scenarios, rover operations, drilling and sample selection, and the interpretation of future in situ measurements.
