Abstract The concept of chirality of a molecule can be used to determine if the molecule’s origin is based on a biological process that we call life. Whether life or life-like biology was present on Mars is still subject to intensive current research. In the near future, ESA’s ExoMars Rosalind Franklin Rover is planned to carry, amongst other, the MOMA instrument suitable to detect the chiral property of molecules and thus contribute to the question of whether Mars once hosted life early on in its history. This review poster will describe a part of ESA’s ExoMars program, the MOMA instrument and what chirality means for life on Earth. This poster is a review poster highlighting the basic concepts of ESA's/NASA's ExoMars Rover aiming at the dectection of biosignature on planet Mars via chirale molecules. This work received financial support from the conference organizer: Centre for Exolife Sciences (CELS) Mission update can be found on ESA's website at:ESA ExoMars mission or at NASA's website at: NASA ExoMars mission
