This composite image of the first borehole drilled by NASA's Perseverance rover on Mars was generated using multiple images taken by the rover's WATSON (Wide Angle Topographic Sensor for Operations and eNgineering) imager. The borehole is 1.06 inches (2.7 centimeters) in diameter. A subsystem of the SHERLOC (Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals) instrument, WATSON can document the structure and texture within a drilled target, and its data can be used to derive depth measurements. The image was taken on the mission's 165th Martian day, or sol, at …
