On Mars, the largest canyon in the solar system could contain large reserves of water

Recent studies reveal significant water reserves on Mars, particularly in the Valles Marineris region, where conditions were thought to prohibit it. These findings, using neutron detection techniques, suggest water may exist in a permafrost-like state, potentially preserving microbial life. The discovery is crucial for future Mars missions, as accessible water could be a valuable resource. Understanding Mars's water history aids in the search for habitable environments and past life. Previous studies also indicated water ice near the equator, supporting these new findings.
