Before collecting a rock sample at a spot nicknamed Lefroy Bay, NASA's Perseverance Mars rover employed an abrasion tool to wear down the rock surface and then used the Planetary Instrument for X-ray Lithochemistry, or PIXL, to study the rock's internal chemistry. This image is composed of multiple shots of the abrasion patch, dubbed Bills Bay, that were taken on Oct. 7 and Oct. 11, 2023, the 935th and 939th Martian days, or sols, of the mission. The image was taken by PIXL's camera, the Autofocus and Context Imager, or ACI. Color was added by overlaying data from WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), a pair of cameras that are part of an instrument called Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals, or SHERLOC. On Earth, both silica and carbonates are good at preserving materials left behind by ancient life. Sand grains made of iron-rich carbonate are also mostly found in places on Earth that are good at protectin
