Mars 2020: SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals)

Mar. 29, 2024. Mars 2020 Release 9 includes new SHERLOC data from sols 900 through 1019, August 31, 2023 through January 1, 2024. See the Release Notes for details.

The Mars 2020 SHERLOC instrument searches for minerals, organic molecules, and potential biosignatures using spectrometers, a laser, and a camera. SHERLOC is mounted on the turret at the end of the robotic arm.

Readme.txt gives a high-level overview of the SHERLOC Bundle.

The SHERLOC Bundle Software Interface Specification (SIS)  describes the contents, format, and structure of the bundle. Users who are unfamiliar with PDS archives should read this first.

The SHERLOC PDS User Guide summarizes information from other documents that is likely to be most useful to the science user.

The SHERLOC EDR SIS and SHERLOC RDR SIS describe the data products generated by the SHERLOC instrument suite, including how they are processed and labeled. The SISs are detailed documents intended for use in mission operations as well as by science users of the archive.
