Scientists using data from the Mars Reconnaissance Orbiter have used radar to measure the deposits of ice beneath Mars's mid-northern latitudes. The depost ranges from 260 to 560 feet thick, and is 50 to 85% water ice. This is comparable to the amount of water in Lake Superior. The ice is close enough to the surface to potentially be a resource for future astronauts.
