An ocean on Mars once held more water than Earth’s Arctic Ocean, according to NASA scientists who measured signatures of water in the planet’s atmosphere.
The results are being published in the journal Science on March 6.
The young Red Planet would have had enough water to cover the whole surface in a liquid layer about 450 feet (137 meters) deep, according to researchers. More likely, they say, the water would have covered almost half of Mars’ northern half, in some places reaching depths greater than a mile (1.6 kilometers).
