About the Journal 

Applied Spectroscopy is one of the world's leading spectroscopy journals, publishing high-quality articles, both fundamental and applied, covering all aspects of spectroscopy. Established in 1948, the journal is owned by the Society for Applied Spectroscopy and is published monthly. The journal is dedicated to fulfilling the mission of the Society to “…advance and disseminate knowledge and information concerning the art and science of spectroscopy and other allied sciences.”  All manuscripts are rigorously peer-reviewed.

Feature Article: "Calibration of the SHERLOC Deep Ultraviolet Fluorescence - Raman Spectrometer on the Perseverance Rover" 


On 18 February 2021, the NASA Perseverance rover touched down in Jezero Crater on Mars. NASA‬ ‪scientists believe that 3.5 billion years ago the area where the crater is located was filled with water, a lake‬ ‪about the size of Lake Tahoe, which created an ancient river delta. According to NASA, the Perseverance‬ ‪mission is to "seek signs of ancient life and collect samples of rock and regolith (broken rock and soil) for‬ ‪possible return to earth".‬ ‪Central to the Perseverance mission is an array of spectroscopy instruments that have been designed to"survive" the landing, stay aligned, and function in the harsh Martian climate which can have daily temperature‬ ‪extremes of –70 to +20 C. The instruments are marvels of science and engineering.‬ ‪At the end of the Perseverance robot arm is the Scanning Habitable‬ ‪Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument. SHERLOC‬ ‪is a combination fluorescence and UV resonance Raman spectrometer whose function is "fine-scale detection‬ ‪of minerals, organic molecules, and potential bio‬-‪signatures". ‬


The feature article in the July issue of Applied Spectroscopy is titled "Calibration of the SHERLOC Deep Ultraviolet Fluorescence–Raman Spectrometer on the Perseverance Rover" by Kyle Uckert et al.  from Jet Propulsion Laboratory (JPL) California, California Institution of Technology, Photon Systems, Inc., University of Pittsburgh Chemistry Department, NASA Johnson Space Center and Jacobs Technology, Inc.  The paper describes the design and calibration procedures for the SHERLOC spectrometer. SHERLOC uses a DUV laser to map a postage stamp-sized area of a rock to characterize mineralogy and organics on the surface of Mars using deep UV Resonance Raman and fluorescence spectroscopy. 


For a related feature read the interview with Professor Sanford Asher on the history and design of the SHERLOC instrument in the April Newsletter!

Did you know?

In 1954 a number of spectroscopists, recognizing the existence of several regional societies of spectroscopists, organized a committee to promote a stronger exchange of information among these societies.  The efforts of this committee resulted in the formation of the Federation of Spectroscopic Societies on March 1, 1956 in Pittsburgh, Pennsylvania.
