ESA To Land Robot on Mars to Search Oxia Planum for Signs of Life
The European Mars mission in 2018 will land on the site identified by Prof Cathy Quantin-Nataf, grantee of the European Research Council (ERC), and her team at Université Lyon 1 and Observatoire de Lyon. Their choice of site, named Oxia Planum, was confirmed by the European Space Agency (ESA) on 21 October as the prime landing site for the robotic mission.
The ESA’s 2018 mission is part of the ExoMars programme to answer one of the outstanding scientific questions of our time – whether life ever existed on Mars. Initially eight landing sites were proposed to ESA in 2014, following an open call for landing site proposals. To find the best spot, the team from Lyon developed a software to analysed large amounts of data collected by previous orbital missions.

“This is how we could identify the “Oxia Planum” site, an unknown place on Mars so far. We proposed Oxia Planum for ExoMars 2018, because it had the potential to fulfill the goal of this space mission, that is to find traces of life,” said Prof. Quantin-Nataf, a geologist specializing in surface of planets.
“We really expect to find there the clues of ancient Mars that would help us understand our own history,” said Prof. Quantin-Nataf. “On Earth we don’t have evidence from the time when life appeared, but Mars stopped its intense geologic activity around 3.5 billion years ago, much earlier than our planet. This gives us a window on the early Earth and on our origin.”
