English: PIA24796: WATSON Image of Perseverance's First Borehole

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 (August 07, 2021), or sol, at night in order to reduce self-shadowing within the borehole that can occur during daylight imaging. Some of WATSON's white LEDs illuminated the borehole.

NASA's Jet Propulsion Laboratory built and manages operations of Perseverance and Ingenuity for the agency. Caltech in Pasadena, California, manages JPL for NASA. WATSON was built by Malin Space Science Systems (MSSS) in San Diego and is operated jointly by MSSS and JPL.
