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]
Researchers have uncovered what may be the oldest direct evidence of hot water activity on Mars, suggesting the red planet could have supported life billions of years ago.. Scientists at Australia ...
[65] [66] [67] In 2018, scientists reported the discovery of a subglacial lake on Mars, 1.5 km (0.93 mi) below the southern polar ice cap, with a horizontal extent of about 20 km (12 mi), the first known stable body of liquid water on the planet, [68] [69] but subsequent work has questioned this detection.

A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
This is the "best evidence yet" that Mars still has liquid water in addition to frozen water at its poles, according to the University of California, San Diego's Scripps Institution of ...
There may be much more water further below the surface; the instruments aboard the Mars Odyssey are only able to study the top meter or so of soil. If all holes in the soil were filled by water, this would correspond to a global layer of water 0.5 to 1.5 km deep. [9] The Phoenix lander confirmed the initial findings of the Mars Odyssey. [10]
NASA has discovered evidence of past water on Mars before, but it’s this narrow band of rock that brings new meaning to this discovery. Using its SHERLOC (Scanning Habitable Environments with ...
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. Mars quickly, over a 1 to 12 million year time span, lost its water, becoming cold and very dry.
