The technology to transfer safely and easily fluids in microgravity is necessary to extend the duration of future space missions. The absence of gravity in space causes fluids to behave much differently than on Earth, making propellant resupply extremely difficult. The Gamma Ray Observatory (GRO) is one of the satellites being designed for refueling. The GRO's thrusters are fueled by the monopropellant hydrazine that as a vapor is unstable above 200 F. This has a major impact on refueling system design and operation. A system using high pressure gas and flexible diaphragms to transfer propellant from a supply vehicle to the GRO was proposed and designed. A ground-based system utilizing the transfer technique of ullage recompression was built to investigate the process.
