Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals

Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) is an ultraviolet Raman spectrometer that uses fine-scale imaging and an ultraviolet (UV) laser to determine fine-scale mineralogy, and detect organic compounds designed for the Perseverance rover as part of the Mars 2020 mission.

SHERLOC has a calibration target with possible Mars suit materials, and it will measure how they change over time in the Martian surface environment.

The Wide Angle Topographic Sensor for Operations and eNgineering (WATSON) is a built to print re-flight that can generate color images over multiple scales.

The deep UV laser is co-boresighted to a context imager and integrated into an autofocusing/scanning optical system that allows correlation of spectral signatures to surface textures, morphology and visible features.

[6][7] Utilizing WATSON and ACI images, there was confirmation that the Jezero Crater floor consists of aqueously altered mafic material with various igneous origins.
