New geological analyses are reinforcing the idea that Mars may have been habitable in the past. Researchers have found evidence that water once circulated beneath the sand dunes of Gale Crater for long periods, possibly much longer than previously thought.
Gale Crater is a 154-kilometer-wide crater located on Mars. Since 2012, the Curiosity rover has been exploring it as part of a geological expedition in search of a potentially habitable world on the planet.
Scientists at New York University Abu Dhabi (NYUAD) have discovered that the ancient dunes in the crater gradually solidified over billions of years after repeated contact with groundwater. The study’s results were published in the journal Journal of Geophysical Research – Planets.
