Using data from NASA's Curiosity rover, scientists at the CNRS, Université Toulouse III – Paul Sabatier and Université Claude Bernard Lyon 1, with the participation of CNES, have discovered patterns on Mars that provide evidence of a cyclical climate similar to that of Earth's. This major discovery opens up new prospects for research into the origin of life. The results of the study are published on 9 August 2023 in the journal Nature.
