Mars Would Have Once More Water Than The Arctic Ocean
According to NASA scientists who measured using ground-based signatures of water in the atmosphere of the red planet, Mars had a primitive ocean that contained more water than the ocean terrestrial Arctic.
There would have been enough water on Mars, perhaps 4.3 billion years to cover the entire surface of the planet in a liquid layer approximately 137 meters deep. More likely, the water would have formed an ocean occupying almost the entire half of the northern hemisphere of the planet, reaching depths in some areas exceeding 1.6 km.
The research team was particularly interested in the regions near the North and South Poles because the polar ice caps contain the largest known reservoir of water on the planet. It is believed that the water stored there recorded the evolution of water on Mars since the time Noachienne, wet, ending there are about 3.7 billion years until today.
