Shallow Subsurface Ice on Mars

Jeffrey J. Plaut, NASA Jet Propulsion Scientist, Reviews the Evidence for Shallow Subsurface Ice on Mars.

The Marsis and Sharad missions to Mars provide evidence of shallow ground ice that is tens of meters from the surface. The overall average is 5-10 meters of thickness across Mars. Out-croppings are spots where the ice is visible. Recent impacts show some ice is only 1 meter from the surface.

There is a lot of accessible ice on Mars in the mid-latitudes. There is also a lot of ice at the poles.
