About
NASA's Perseverance Mars rover used its WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) camera to take eight images – combined here into the single composite image – of a rock abraded by a tool on the rover's robotic arm. The images were taken on Aug. 27, 2021 (the 185th Martian day, or sol, of the mission). Nicknamed "Bellegarde," the abraded target is 0.4 inches (5 centimeters) in diameter. A subsystem of SHERLOC, WATSON can document the structure and texture within a drilled or abraded target, and its data can be used to derive depth measurements. The area within the blue box is roughly 6.5 millimeters squared. NASA's Jet Propulsion Laboratory built and manages opera — NASA JPL · 2021.
