NASA's Perseverance rover identified light-colored rocks in Jezero crater that consist of white, aluminum-rich kaolinite clay. These rocks formed after prolonged exposure to water leached other minerals from parent rocks and sediments. The process required millions of years of rainfall in a humid environment.
Perseverance's SuperCam and Mastcam-Z instruments analyzed the kaolinite fragment
