ExoMars eyes ancient Martian clay beds for signs of life

ESA’s Rosalind Franklin rover will land at Oxia Planum to study vast clay-bearing sediments that extend toward Mawrth Vallis, hinting at extensive past water activity and possibly an ancient ocean. The mission will drill up to two metres and analyze samples to search for biosignatures while orbiters show similar mineral layers and a paused deposition history, informing Mars’ early climate and habitability and helping reconstruct its water history.

Unveiling the Mysteries of Mawrth Vallis: ESA's Exploration of Clays

ESA's Mars Express has captured new images of Mawrth Vallis, a promising location in the search for signs of life on Mars. The images reveal the distinctive features of the region, including the martian dichotomy boundary and the presence of light-toned clays rich in iron, magnesium, and aluminum. These clays provide evidence of past abundant water on Mars and raise the possibility of preserved microbes. The images also showcase the transition from highland to lowland terrain, with eroded craters, mesas, and evidence of previous impact events. Mars Express has been instrumental in mapping Mars's surface and deepening our understanding of the planet.
