Astrobiological Potential of Rocks Acquired By the Perseverance Rover in Jezero Crater, Mars

The scientific community has prioritized the return of Martian rock samples with known geologic context for more than a decade (Beatty et al., 2019). Thus, the main objectives of the Perseverance rover mission on Mars include identifying past habitable environments, collecting rocks that are likely to preserve biosignaturesand using the rover’s instruments to look for potential biosignatures in these rocks (Farley et al., 2020). Here, we present an overview of the bedrock samples collected bythe Perseverance rover in Jezero crater to date and discuss the potential of the sampled materials to address astrobiological questions upon sample return to Earth.
