An artist's impression of ancient Mars and its oceans based on geological data The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [1] The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the ...
The Mars ocean hypothesis proposes that the Vastitas Borealis basin was the site of an ocean of liquid water at least once, [23] and presents evidence that nearly a third of the surface of Mars was covered by a liquid ocean early in the planet's geologic history.
On March 5, 2004, NASA announced that Spirit had found hints of water history on Mars in a rock dubbed "Humphrey". Raymond Arvidson , the McDonnell University Professor and chair of Earth and planetary sciences at Washington University in St. Louis , reported during a NASA press conference: "If we found this rock on Earth, we would say it is a ...
But the finding uncovers new details about the geological history of Mars — and suggests a new place to search for life on the red planet if the water could ever be accessed.
They proposed dividing the history of Mars into three eras: the Phyllocian, Theiikian and Siderikan. [18] [19] The Phyllocian (named after phyllosilicate or clay minerals that characterize the era) lasted from the formation of the planet until around the Early Noachian (about 4.0 Gya).
Mars may be drenched beneath its surface, with enough water hiding in the cracks of underground rocks to form a global ocean, new research suggests. The findings released Monday are based on ...
This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
