Raman spectroscopy is a nondestructive technique for material identification. It is fast, unique, and needs no preparation of the investigated sample and is thus very suitable for measurements in extreme situations and environments like on other planets, on moons, asteroids, and comets. There will be in the near future (RLS on ESAs Exo-Mars in 2020 and SuperCam on NASAs Mars2020) Raman spectrometers on missions to Mars available that will provide new inside in the to the composition and structure of any mineral or organic compound. This capability provides direct information of potential organic compounds that can be related with present or past signatures of life on Mars as well as general mineralogical information for igneous, metamorphous, and sedimentary processes, especially water-related geo-processes.
The main goal of this working group is the processing of diverse space-relevant issues/topics/subjects by using Raman spectroscopy. As a member of the ExoMars-RLS science team we investigate the influence of the extreme environmental conditions on the Raman measurements and spectra.
