Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals

SHERLOC's calibration target aboard the *Perseverance* Mars rover with Mars Meteorite in the centre of top row

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.^[1]^[2]^[3] It was constructed at the Jet Propulsion Laboratory with major subsystems being delivered from Malin Space Science Systems and Los Alamos National Laboratory.

SHERLOC has a calibration target with possible Mars suit materials, and it will measure how they change over time in the Martian surface environment.^[4]
