In January 2024, the SHERLOC<\/a> instrument aboard NASA\u2019s Mars 2020 Perseverance rover<\/a> encountered a significant issue. A \u00a0fault<\/a> in the instrument\u2019s motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover\u2019s SHERLOC Raman spectroscopy capability at risk.<\/p>\nAlthough Mars had posed an unexpected challenge, members of the SHERLOC operations team working together with the rover engineers refused to give up.<\/p>\nFortunately, a motion of the arm on Sol 1077, almost exactly two months after the original issue occurred, resulted in the dust cover moving to a nearly fully open position. As a result, the team began to look for ways to focus the optics and operate SHERLOC with the dust cover in this open position. These efforts involved many trials and errors, several rounds of diagnostic examinations, analyses, and troubleshooting around the clock.<\/p>\nAnd as they say, \u201cIt does not matter how slowly you go so long as you do not stop\u201d.<\/p>\nAfter much hard work and persistence, the team successfully brought the SHERLOC instrument back online<\/a> in June 2024 with a successful observation of the rock target Walhalla Glades<\/a>. It was just the start of an exciting summer for SHERLOC.<\/p>\nIn July 2024, SHERLOC\u2019s Raman capability, whose destiny was uncertain a month ago, performed multiple calibrations, scans, and observations on a rock named \u201cCheyava Falls\u201d and the team was thrilled to discover the mission\u2019s most compelling evidence for organics in the Jezero crater. Organic compounds can be formed through biological or non-biological processes and the organics that SHERLOC observed in Cheyava Falls would need to be studied in laboratories here on Earth for their origin to be determined. Regardless of how they formed, the Cheyava Falls organics could tell us a great deal about the Red Planet\u2019s past and present carbon inventory, a possible early carbon cycle, and the precursor conditions to life as we know it.<\/p>\nIt is an important and exciting juncture in Mars exploration and astrobiology. This year, the SHERLOC instrument beat the odds and made one of the most exciting discoveries of the Mars 2020 mission. As the mission encounters and overcomes problems like that experienced by SHERLOC, we find that exploring Mars can also lead to discovering the team\u2019s persistence and Perseverance<\/em>.<\/p>\nWritten by Anushree Srivastava, Postdoctoral Fellow at Carnegie Institution.
