Perseverance rover finds clay minerals in Mars’ Jezero Crater, indicating ancient rainfall and potential habitability.
NASA’s Perseverance rover has found pale, bleached rocks in Mars’ Jezero Crater containing kaolinite, a clay mineral that forms on Earth only through prolonged rainfall over millions of years.
This discovery suggests Mars once had a warm, wet climate with sustained precipitation, possibly resembling a tropical environment, billions of years ago.
Researchers from Purdue University, analyzing the samples, say the mineral’s presence indicates stable liquid water and a thicker atmosphere, conditions that could have supported microbial life.
The findings, published in Communications Earth & Environment, represent some of the strongest direct evidence yet of Mars’ ancient habitability.
