NASA consistently strives to reduce the cost of space missions and to reduce the use of toxic chemicals. The proposed technology significantly reduces the cost of space missions by reducing the cost of the propellants, and by eliminating the cost of handling and processing toxic propellants. A low-cost non-toxic in-space propulsion system with state-of-the-art performance has NASA applications including main spacecraft propulsion, orbital maneuvering systems, reaction control systems, and auxiliary power units. A low-cost, non-toxic storable propulsion system has many non-NASA commercial applications. The propulsion system could be used as a Rocket Assisted Take-Off (RATO) systems for Un-crewed Aircraft Systems (UAS) to increase gross takeoff weight while maintaining safe ground operations, or as a self-contained Auxiliary Power Unit (APU). Additionally, it offers safe, high-performance in-space propulsion for the growing commercial space industry.
