Mars 2020 Perseverance SHERLOC WATSON Camera Pre-delivery Characterization and Calibration Report
Abstract and Figures
This document is the 03 December 2019 pre-ship characterization and calibration report for the WATSON camera launched 30 July 2020 onboard the Perseverance rover, bound for Mars. WATSON, a Wide Angle Topographic Sensor for Operations and eNgineering camera, is a subsystem of the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument mounted on the turret at the end of Perseverance’s robotic arm. The WATSON characterized in the 03 December 2019 report was the Flight Spare unit; by the time it was delivered to JPL-Caltech in October 2019, it had become the baseline flight instrument, intended for launch to Mars. A previous WATSON camera head became the Mars 2020 testbed article (testbed-WATSON). “Pre-ship” refers to testing and activities performed before the WATSON camera head was delivered from Malin Space Science Systems (MSSS, San Diego, California, USA) to the California Institute of Technology’s Jet Propulsion Laboratory (Caltech JPL, Pasadena, California, USA), where WATSON was subsequently integrated with the SHERLOC Turret Assembly (STA). The STA was, in turn, integrated with the Perseverance rover at JPL.
