Today Mars is dry, cold and has an atmosphere a hundred times thinner than the Earth’s. However, more than 3.7 billion years ago Mars was likely more humid and warmer than our planet today. But how was this possible? A new study by Benjamin Bultel and coworkers from CEED, IMPMC (Institut de Minéralogie, Physique des Matériaux et Cosmochimie) and IAS (Institut d’Astrophysique Spatiale), published in the Journal of Geophysical Research-Planets, has discovered a new piece of puzzle of the early Mars climate. They found that surface carbonates formed in a CO2-rich atmosphere that was much thicker than present.
