This illustration depicts the mechanism and conceptual research targets for an instrument named Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals, or SHERLOC. This instrument has been selected as one of seven investigations for the payload of NASA's Mars 2020 rover mission. SHERLOC will be a spectrometer that will provide fine-scale imaging and use an ultraviolet laser to determine fine-scale mineralogy and detect organic compounds.
