Scientists Discover Hidden Water Beneath Mars that Could Have Supported Life
The study suggests underground water kept Mars habitable longer and left gypsum-rich deposits that could preserve signs of ancient life.
- A New York University Abu Dhabi study revealed that groundwater moved beneath Mars' surface billions of years ago, cementing sand dunes in Gale Crater by comparing rover observations with desert formations in the United Arab Emirates.
- Findings suggest Mars did not simply transition from wet to dry; small amounts of water persisted underground long after surface lakes vanished, creating protected environments that could have potentially supported microscopic life.
- The team identified minerals like gypsum, which formed when moisture moved through sand and crystallized approximately 757 million years ago, with blade-like crystal clusters providing evidence of this ancient fluid activity.
- Because groundwater is shielded from harsh surface radiation and oxidizing chemicals, these subsurface deposits represent promising targets for future missions, strengthening the case that life could have persisted on the Red Planet long after surface water disappeared.
- Broader research confirms Jezero Crater experienced multiple distinct episodes of fluid alteration, and scientists are now using these findings to guide Perseverance's sampling strategy to determine whether organic carbon originated from biological or geological processes.

Perseverance Finds Organic Carbon Preserved Just Beneath the Martian Surface
Perseverance has found shallow preserved organic carbon on Mars, raising new questions about ancient Martian environments. Mars keeps offering clues that are promising enough to study, but not definitive enough to settle the biggest question. In September of last year, NASA reported that its Perseverance rover had found a potential biosignature, a substance or structure [...]
In recent years, there has been an increase in evidence that there was life on Mars. The focus at the Space Congress Costar in Florence is on the topic. The European mission ExoMars could become decisive.
Scientists discover hidden water beneath Mars that could have supported life
New research suggests Mars may have remained habitable much longer than scientists once thought. Ancient sand dunes in Gale Crater appear to have been soaked by underground water billions of years ago, leaving behind minerals that can preserve signs of life. Even after surface water disappeared, subsurface flows may have created protected environments for microbes. These hidden habitats could be key targets in the ongoing search for past life on…
