“Buried!” –Mars’ Ancient North Pole Ice Sheets Found

Mars North Pole

Newly discovered layers of ice buried a mile beneath Mars’ north pole are the remnants of ancient polar ice sheets and could be one of the largest water reservoirs on the planet, according to scientists at The University of Texas at Austin and the University of Arizona, using measurements gathered by NASA’s Mars Reconnaissance Orbiter (MRO) and the Shallow Radar (SHARAD) that emits radar waves that can penetrate up to a mile and a half beneath the surface. If melted, the newly discovered polar ice would be equivalent to a global layer of water around Mars at least 1.5 meters (5 feet) deep.
