flag Perseverance rover finds clay minerals in Mars’ Jezero Crater, indicating ancient rainfall and potential habitability.

flag 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. flag This discovery suggests Mars once had a warm, wet climate with sustained precipitation, possibly resembling a tropical environment, billions of years ago. flag 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. flag The findings, published in Communications Earth & Environment, represent some of the strongest direct evidence yet of Mars’ ancient habitability.
