Lunar Materials Analyzer (LuMA)

Optimizing lunar regolith ISRU and construction processes requires the knowledge of the raw materials composition. We propose to develop a Lunar Materials Analyzer (LuMA) which primary functions are to monitor the mineral phase composition and the elemental composition of a lunar regolith feedstock of ISRU or construction processes. LuMA uses X-ray diffraction (XRD) and X-ray fluorescence (XRF), two analytical techniques that are well proven and have already been developed for in-situ planetary science. This SBIR will 1) adapt proven planetary science instrument technologies to the constraints and requirements of in-line analysis, 2) develop a robust robotic sample handling system for maintenance-free operation on the surface of the moon over periods exceeding one year, 3) automate XRD and XRF data interpretation, 4) investigate additional analytical capabilities for measurements such as regolith softening and melting points, and/or the viscosity of a melt. The Phase I research will focus on concept refinement and demonstration of feasibility, with a particular focus on the XRD instrument geometry and XRD sample configuration, and XRF optimization. The work will be approached via simulations and experimentation with existing prototypes modified to test new layouts. Foreseen NASA markets are future ISRU applications, missions intended to identify/quantify resources, and robotic or astronaut-operated instruments for in-situ science. Commercial markets are automated applications of XRD and/or XRF for in-line monitoring of raw materials or products, in industries such as cement, mining, petroleum, pharma, food, etc.
