Combined use of ExoMars2022 Rover Drill telemetry and the data from ADRON, CLUPI, Ma_MISS and WISDOM instruments for a full characterization of Oxia Planum shallow subsurface environment

Abstract : Due to the thin Martian atmosphere the action of UV and ionizing radiations damage potential chemical biosignatures at or in the vicinity of the surface. Their long-term effects are expected to decrease with depth and accessing to the Martian shallow subsurface, where samples of astrobiological interest can be better preserved, is a crucial step for searching for possible signs of life (past and present). In order to assess the presence of organic molecules and potential biomarkers in the subsurface, the ESA/Roscosmos Rosalind Franklin Rover is equipped with a Drill able to collect samples down to a depth of 2 m for the first time on Mars. Here we propose to use the Drill telemetry in synergy with data from Rover instruments dedicated to subsurface investigations (ADRON, CLUPI, Ma\_MISS and WISDOM) to better characterize the subsurface stratification, compositional variations and connection with surface morphology for a thorough understanding of the geological history of Oxia and a proper selection of the drilling site.
