In July 2019, support was reported for an ancient ocean on Mars that may have been formed by a possible mega-tsunami source resulting from a meteorite impact creating Lomonosov crater. [44] [45] In January 2022, a study about the climate 3 billion years ago on Mars shows that an ocean is stable with a water cycle that is closed. [46]

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]
The Noachian period occurred from 4.1 to 3.7 billion years ago, and little is known from direct measurements dating to the pre-Noachian period on Mars, between 4.5 billion and 4.1 billion years ...
While meteorites in the same family as NWA 7635 were all dated about 500 million years old — meaning they were formed from cooling magma on the surface of Mars circa half a billion years ago ...
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 water — believed to be seven miles to 12 miles (11.5 kilometers to 20 kilometers) down in the Martian crust — most likely would have seeped from the surface billions of years ago when Mars harbored rivers, lakes and possibly oceans, according to the lead scientist, Vashan Wright of the University of California San Diego’s Scripps ...
Mars in true color, taken by the Emirates Mars Mission on 30 August 2021, when Mars was in northern solstice. The Mars carbonate catastrophe was an event that happened on Mars in its early history. Evidence shows Mars was once warmer and wet about 4 billion years ago, that is about 560 million years after the formation of Mars.
