Thin Ice, Hidden Lakes: Mars May Harbor Decades-Long Water Under Seasonal Ice
A new LakeM2ARS climate model shows ancient Martian lakes could endure for decades beneath thin, seasonal ice, insulating water enough to stay liquid in a cold, CO2-rich early Mars. By adapting Earth-based Proxy System Modeling, researchers ran 64 simulations across varied conditions, suggesting minimal ice can preserve lakes without leaving obvious glacial traces. If confirmed, this helps explain geological evidence of past water and prompts applying the model to other regions to reassess Mars’ habitability.
