NASA's InSight lander measured Marsquakes, and now its data is hinting there's a reservoir of liquid water under the planet's surface. Another point for life on Mars: Signs of liquid water ...
Calculations show that the lineae are active between minus 27 degrees C and minus 9 degrees C to display the activity observed. Water would do this if it was in a brine having of tens of wt% salt. [12] Although these features were initially thought to be evidence of current water flow, some studies show that little or no water may be involved.
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. ... liquid water likely made its ...
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
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.

In June 2000, possible evidence for current liquid water flowing at the surface of Mars was discovered in the form of flood-like gullies. [137] [138] Additional similar images were published in 2006, taken by the Mars Global Surveyor, that suggested that water occasionally flows on the surface of Mars. The images showed changes in steep crater ...
If the InSight location is representative and you extract all the water from the fractures in the mid-crust, we estimate that the water would fill a 1-2 km deep (0.6-1.2 miles) ocean on Mars ...
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]
