Perseverance grinds circular patches into rocks so its science instruments can analyze the rocks' composition. The images were taken by the WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera on the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument. The camera that took these images, located at the end of Perseverance's robotic arm, was about 3 inches (7 centimeters) away from the rock surface.
