Perseverance Finds a Field of Pale Rock Where Mars Is Mostly Dark

After six months exploring “Lac de Charmes,” a region of ancient rock beyond the western rim of Jezero crater, NASA's Perseverance rover came upon a vast field of light-toned rocks scattered across the Martian surface. On a planet dominated by dark basaltic rock, light-colored stone is a strange sight — which makes a whole field of it worth a closer look.
