“…As a consequence, the abundance pattern of amino acids, i.e. the ratio of various amino acids to Gly, can be considered as a biosignature (Davila and McKay 2014;Creamer et al 2017;Klenner et al 2020a;Taubner et al 2019).…”

“…Furthermore, biotic and abiotic signatures can be mimicked and detection limits for the instruments in space can be predicted. Figure 3 shows cationic laboratory mass spectra of 50 ppmw glutamic acid (top) and of a variety of amino acids, each at a concentration of 50 ppmw (bottom), dissolved in water (Klenner et al 2020a). The protonated molecular peaks and certain characteristic fragments are easily detectable.…”

“…However, the varying amplitudes of the different amino acids (Fig. 3 bottom) indicate varying sensitivities dependent on the tendency of the species to form cations (Klenner et al 2020a).…”

“…However, to be able to interpret the data collected by instruments on board of missions, such as NASA's Cassini or ESA's JUICE (JUpiter ICy moons Explorer) probes, we have to conduct laboratory experiments to simulate the effects particles experience during such high-speed in situ sampling. For this purpose, both light gas guns (Grey et al 2001;Harriss and Burchell 2017;Shengwei et al 2017;Bowden et al 2009;Judge 2017;Fisher et al 2018;Fujishima et al 2016;Lexow et al 2013;Hibbert et al 2017;Carver et al 2008;Ramkissoon 2016) and laser induced liquid beam desorption (Postberg et al 2009b(Postberg et al , 2018bKlenner et al , 2020a) can be used. The resulting atomic, molecular, and macroscopic fragments are then analysed using mass spectrometers.…”

“…The resulting atomic, molecular, and macroscopic fragments are then analysed using mass spectrometers. The inclusion of such spectrometers on board of future space missions (Kempf et al 2012;Lunine et al 2015;Reh et al 2016;Mitri et al 2018;Brockwell et al 2016;Barabash et al 2013) could help to detect potential characteristic patterns of biosignatures like amino acids, fatty acids, and peptides (Davila and McKay 2014;Creamer et al 2017;Klenner et al 2020a;Georgiou and Deamer 2014). At present, these in situ measurements are cost effective alternatives to sample return mission concepts.…”

The icy satellites of Jupiter and Saturn are perhaps the most promising places in the Solar System regarding habitability. However, the potential habitable environments are hidden underneath km-thick ice shells. The discovery of Enceladus' plume by the Cassini mission has provided vital clues in our understanding of the processes occurring within the interior of exooceans. To interpret these data and to help configure instruments for future missions, controlled laboratory experiments and simulations are needed. This review aims

The Europa lander is a concept for a potential future planetary exploration mission which purpose is to characterize the icy shell of Europa and to search for organics. To achieve this objective, the current concept of the lander includes a Raman spectrometer, such as RLS instrument, that could be able to analyze (sub) surface targets in their solid and liquid form. Knowing that ice and brines of Europa are potentially enriched by sulfate and chlorides, this work seeks to evaluate if Raman spectroscopy could be used to semi quantify the saline content of water solutions using space-like instrumentation. To do so, MgSO 4 and MgCl 2 were used to prepare three sets of water solutions. Raman analyses were then performed by the laboratory simulator of the ExoMars Raman Laser Spectrometer (RLS), which has been defined as the threshold system for the Europa Lander. After data analysis, two different semi-quantification approaches were tested, and their results compared.Although univariate calibration curves proved to successfully quantify the content of SO 4 2À and Cl À anions dissolved in mono-analyte water solutions, this strategy provided very poor results when applied to binary saline mixtures. Overcoming this issue, the non-linearity prediction ability of Artificial Neural Networks (ANNs) in combination with bandfitting allows to successfully resolve the complexity of the vibrational perturbation suffered by the OH region, which is caused by the cross interaction of H 2 O molecules with different anions.
