A giant deposit of buried ice on Mars contains about as much water as Lake Superior of French, a new study reveals.
Using data from NASA's Mars Reconnaissance Orbiter, scientists have discovered a large deposit of ice beneath a region of cracked and pitted plains on Mars, reports Space.com.
The ice layer, which spans a greater area than the state of New Mexico, lies in Mars' mid-northern latitudes and is covered by just 3 feet to 33 feet (1 to 10 meters) of soil.
It therefore represents a vast possible resource for future astronauts exploring the Red Planet, study team members said.
"This deposit is probably more accessible than most water ice on Mars, because it is at a relatively low latitude and it lies in a flat, smooth area where landing a spacecraft would be easier than at some of the other areas with buried ice," co-author Jack Holt, of the University of Texas, Austin, said in a statement.
The newly surveyed ice deposit represents less than one percent of all known water ice on Mars, the study said.
