“…Identification of mineral species is achieved by using the RRUFF Database within the Crystal Sleuth software (Laetsch and Downs, 2006;Downs et al, 2015). The following references for each mineral were considered alongside the spectral analyses: oxides (Balachandran and Eror, 1982;Wang et al, 2004;Markovski et al, 2017), carbonates (Rull-Perez and Martinez-Frias, 2003;Buzgar and Apopei, 2009), pyroxenes (Huang et al, 2000;Wang et al, 2001), feldspar (Freeman et al, 2008;Lalla et al, 2015Lalla et al, , 2019, clays (Apopei and Buzgar, 2010;Lalla et al, 2016;Black and Hynek, 2018), and organics (Ferrari, 2007). The organics present in the main Raman bands in the range of 2800 to 3000 cm -1 correspond to C-H bonding, and the other less intense bands *1300 cm -1 correspond to C-C vibrations (Beegle et al, 2015).…”

“…The identification for each mineral resulted from the band analyses using the following references: oxides, [1,[38][39][40][41] carbonates, [42][43][44][45] silicates, [1,45,46] feldspar and plagioclases, [40,45,47,48] nesosilicates, [49,50] and garnets.

“…[10] In the context of planetary exploration, Raman spectroscopy is an excellent tool for the identification and quantification of minerals, [11][12][13] capable of detecting the presence of organic materials and characterizing some organic molecules. [1,[14][15][16] Raman spectroscopy has emerged as a promising method for planetary exploration due to its excellent analytical capabilities, the fact that it requires effectively no sample preparation, and the fast speed of the chemical analysis. It is used on the Mars 2020's Perseverance rover-the SHERLOC [17] and SuperCam [18] instruments-and at the time of this writing is scheduled to be onboard the upcoming ExoMars 2022 mission-the Raman Laser Spectrometer (RLS) instrument.…”

Between February 1 and February 28, 2018, the Austrian Space Forum, in cooperation with research teams from 25 nations, conducted the AMADEE-18 mission-a human-robotic Mars expedition simulation in the Dhofar region in the Sultanate of Oman. As a part of the AMADEE-18 simulated Mars human exploration mission, the Remote Science Support team investigated the Dhofar area (Oman) to qualify it as a potential Mars analog site. The motivation of this research was to study and register selected samples collected by the analog astronauts during the AMADEE-18 mission with the European Space Agency (ESA) ExoMars Raman Laser Spectrometer (RLS) simulator, compare the results with standard laboratory measurements, and establish the implication of the results to the future ESA ExoMars mission. The Raman measurements identified minerals such as carbonates (calcite and dolomite), feldspar and plagioclase (albite, anorthite, orthoclase, and sanidine), Fe-oxides (goethite, hematite, and magnetite), and Ti-oxide (anatase), each relevant to planetary exploration. As we have presented here, Raman spectroscopy is a powerful tool for detecting the presence of organic molecules, particularly by analyzing the principal vibration of C C and C H bonds. It has also been shown that portable Raman spectroscopy is a relevant tool for in situ field studies such as those conducted during extra-vehicular activities (EVA) in simulated missions like the AMADEE-18 and the future AMADEE-2020 campaign.

The Raman laser spectrometer (RLS) instrument onboard the Rosalind Franklin rover of the ExoMars 2022 mission will analyze powdered samples on Mars to search for traces of life. To prepare for the mission, the RLS scientific team has developed the RLS ExoMars Simulator (RLS Sim), a flexible model of RLS that operates similarly to the actual instrument, both in laboratory and field conditions, while also emulating the rover operational constraints in terms of sample distribution that are relevant to the Raman analysis. This system can operate autonomously to perform RLS-representative analysis in one or several samples, making it very useful to perform heavy experimental tasks that would otherwise be impossible using a flight-representative model of the instrument. In this work, we introduce the current configuration of the RLS Sim that has incorporated new hardware elements such as the RAman Demonstrator 1 (RAD1) spectrometer with the objective of approaching its performance to that of the actual RLS instrument. To evaluate the scientific capability of the RLS Sim, we have compared it with a replica model of RLS, the RLS Flight Spare (FS). Several acquisition aspects have been evaluated based on the analysis of select samples, assessing the performance in terms of spectral range and resolution and also studying several issues related to the evolution of signal-to-noise ratio (SNR) with different acquisition parameters, especially the number of accumulations. This performance analysis has shown that the RLS Sim in its updated configuration will be a key model to perform support science for the ExoMars mission and the RLS instrument on the
