New View of Ancient Mars Water System
Groundwater once bubbled up from beneath the surface of Mars to form transient, shallow pools before evaporating and leaving behind thick layers of salty minerals, a new computer model suggests.The new model provides an alternative explanation for sulphate-rich “evaporite” deposits discovered on Mars’ Meridiani Planum, hailed by some scientists as the desiccated remains of an ancient ocean covering the planet’s Northern Plains. It also suggests Mars in its early history had a globally connected groundwater system.
