On March 2, 2004, NASA announced that "Opportunity has landed in an area of Mars where liquid water once drenched the surface". Associate administrator Ed Weiler told reporters that the area "would have been good habitable environment", although no traces of life have been found. Larger grains suggest the presence of fluid.
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]
Scientists discovered signs of an ocean's worth of liquid water miles below Mars' surface. The findings, based on Marsquake measurements by NASA's InSight lander, could help solve a mystery.
In 2018, it was announced that a subglacial lake was discovered below the south polar ice cap of Mars. The lake was detected by Mars Express orbiter, and is 20 km (10 mi) long, lying under ca. 1.5 km (1 mi) of glacial cover, with water temperature estimated to be −68 °C (−90 °F), and having an extremely salty brine.

Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
The temperature and pressure makes stable liquid water unlikely at the red planet’s surface, researchers have said. Liquid water spotted on Mars may just be an illusion, study suggests Skip to ...
Lake Vostok and other subglacial rivers and lakes in Antarctica. [16] (Image credit: NASA.) The putative subglacial lakes are of interest for the possibility of supporting life. [34] If physical conditions allowed one location of subglacial liquid water on Mars to exist, then this might extend to other subsurface biospheres on the planet. [35]
NASA's Perseverance rover found water, organics, and chemical energy in a Martian rock, hinting at possible ancient microbial life. NASA Made a World-Shaking Discovery: Compelling Evidence of Past ...
