            SHERLOC is a deep UV resonance Raman and fluorescence spectrometer carried on the 
            end of the Mars 2020 Rover robotic arm for detection and characterization of 
            organics and minerals in the Martian surface and near subsurface. SHERLOC includes an 
            Autofocus Context Imager (ACI) and a Wide Angle Topographic Sensor for Operations and 
            eNgineering camera (WATSON).
