Art illustration of liquid water in the upper crust on Mars. (IMAGE)
Caption
Using reasonable estimates of heat flux and thermal conductivity, porosity in the mid-crust has been eliminated. Based on calculations of thermal gradients, temperatures at depths greater than 5 km would exceed the freezing point, enabling liquid water storage at the base of the upper crust.
