Scientists have uncovered compelling evidence suggesting that early Mars was surprisingly wet, featuring extensive networks of lakes and river basins shaped by rainfall and snowfall. This challenges long-held views of a predominantly cold and icy ancient Mars. Despite current climate models struggling to explain sustained liquid water on the Red Planet, geological features explored by NASA’s Perseverance rover and analyzed through new precipitation models point to a more Earth-like past. This research not only deepens our understanding of Mars’ history but also offers valuable insights into the early evolution of our own planet.
