<\/figure>\nNASA\u2019s Perseverance puts its robotic arm to work around a rocky outcrop called \u201cSkinner Ridge\u201d in a set of images captured in June and July 2022 by the rover\u2019s Mastcam-Z camera system. SHERLOC is mounted on the end of the arm.<\/div>\nNASA\/JPL-Caltech\/ASU\/MSSS<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\nEngineers are working to stabilize a dust cover on one of the science instrument\u2019s cameras<\/em>.<\/p>\nData and imagery from NASA\u2019s Perseverance Mars rover indicate one of two covers that keep dust from accumulating on the optics of the SHERLOC instrument remains partially open. In this position, the cover interferes with science data collection operations. Mounted on the rover\u2019s robotic arm, SHERLOC<\/a> (Scanning Habitable Environments with Raman & Luminescence for Organics and Chemicals) uses cameras, a spectrometer, and a laser to search for organic compounds and minerals that have been altered in watery environments and may be signs of past microbial life.<\/p>\nThe mission determined on Jan. 6 that the cover was oriented in such a position that some of its operation modes could not successfully operate<\/a>.

SHERLOC is part of a seven-instrument suite on Perseverance.
