CRISM was being used to identify locations on Mars that may have hosted water, [1] a solvent considered important in the search for past or present life on Mars.In order to do this, CRISM was mapping the presence of minerals and chemicals that may indicate past interaction with water - low-temperature or hydrothermal.

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.
The blue region of low topography in the Martian northern hemisphere is hypothesized to be the site of a primordial ocean of liquid water. [183] 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 ...
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 ...
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.
Mars Express data shows that water molecules float higher than usual during the planet's warmer seasons, avoiding an Earth-like "cold trap" that keeps water close to the ground.

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 ...
