RLS iOH: ExoMars Raman laser spectrometer optical head bread board to flight model design and performance evolutions

Problems in agricultural development often encountered in almost all regions in Indonesia are the inadequate use of natural resource potentials, limited ability to manage resources, and lack of synergy between economic actors. These various problems require improved performance through integrated management and development of commodities from upstream to downstream. This research aims to design a working model for the development of local superior commodities in Sukabumi Regency through a survey method conducted in 33 subdistricts. The research resulted in a working model design for the development of local superior commodities in Sukabumi Regency which involved aspects of resource contribution (labor/human resources, natural resources, capital and infrastructure) as well as aspects of work and performance (farmer institutions, extension agencies, financial and marketing institutions, education, training, experiences, sales ability and product demand) to be able to generate advantages. Until now, agricultural development is still facing various obstacles and added value (profitability, market, productivity and learning). All components in the working model design for developing local superior commodities in Sukabumi Regency must be supported by government policies to maximize the increase in added value for both farmers and the community

Abstract This work aims to evaluate whether the multi-point analysis the ExoMars Raman Laser Spectrometer (RLS) will perform on powdered samples could serve to classify ultramafic rocks on Mars. To do so, the RLS ExoMars Simulator was used to study terrestrial analogues of Martian peridotites and pyroxenites by applying the operational constraints of the Raman spectrometer onboard the Rosalind Franklin rover. Besides qualitative analysis, RLS-dedicated calibration curves have been built to estimate the relative content of olivine and pyroxenes in the samples. These semi-quantitative results, combined with a rough estimate of the concentration ratio between clino- and ortho-pyroxene mineral phases, were used to classify the terrestrial analogues. XRD data were finally employed as reference to validate Raman results. As this preliminary work suggests, ultramafic rocks on Mars could be effectively classified through the chemometric analysis of RLS data sets. After optimization, the proposed chemometric tools could be applied to the study of the volcanic geological areas detected at the ExoMars landing site (Oxia Planum), whose mineralogical composition and geological evolution have not been fully understood.
