We are proposing the research and development of a calibration-free sensing suite for contaminant detection and conversion efficacy analysis of emerging in-situ resource utilization (ISRU) propellant production technologies for future Martian missions. The Phase I effort will focus on developing a spectroscopic strategy to (1) detect select trace-level (ppm) contaminants (CO, HCl) in fuel and oxidizer streams produced by emerging catalytic electrolyzers, and (2) analyze the conversion efficiency and reaction progress of CH4 from CO2 in the Martian atmosphere. The results will inform Phase-II development of a modular sensing suite with low system size, weight, and power (SWaP) for real-time monitoring of the health and efficiency of catalytic electrolyzer technologies. Our unique and synergistic teaming strategy ensures that successful execution of this project will not only advance sensors optimized for monitoring ISRU propellant production, but also help further the Technology Readiness Level (TRL) for emerging catalytic electrolyzer technologies. Anticipated
Benefits: The ISRU sensor will directly support NASA initiatives for human exploration. Future astronauts will require the ability to collect space-based resources and transform them into breathable air; water for drinking, hygiene, and plant growth; rocket propellants; building materials; and more. Mission capabilities and net value will multiply when useful products can be created from extraterrestrial resources. Sensors resulting from this project will provide an extremely attractive alternative to existing gas diagnostics for a wide range of commercial applications. The ability to perform trace-gas analysis in a small, compact system is beneficial for environmental monitoring (e.g., greenhouse analysis) and process control (e.g., contaminant quantification).
