LONDON: In the distant past, Mars had a vast ocean a big as the Arctic, according to a team of scientists at NASA. In the journal Science, NASA scientists published a new study about Mars having a giant body of water millions or billions of years ago. The size of the said body of water is large enough to shield the entire planet surface. It is absolutely bigger than Earth’s Arctic Ocean.
About four billion years ago, the young planet would have had enough water to cover its entire surface in a liquid layer about 140 meters (450 feet) deep. But, the researchers say, it’s more likely that the water would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometers (1 mile).
