New findings from NASAâs Perseverance in Jezero Crater suggest Mars during the Noachian epoch (about 4.1â3.7 billion years ago) was warmer and wetter than previously believed, with evidence of persistent rainfall indicated by kaolinite-rich clays and weathered rocks, challenging the cold, icy Mars theory and implying habitable conditions in the distant past.
NASAâs Perseverance rover found thousands of kaolinite-rich rocks in Jezero crater, minerals that form with long-term water exposure, strengthening evidence that Mars was once warmer and wetter with rainfall-driven weathering; the rocksâ exact source is unclearâpotentially transported by ancient rivers or ejected by meteorite impacts from nearby terrain.
NASA's Perseverance rover discovered light-colored, kaolinite-rich rocks on Mars, suggesting the planet once had a tropical, rainy climate with water environments similar to Earth's, raising the possibility that Mars could have supported life in the past.
