The Swingbed software applications provide for the control, command, fault detection, fault recovery, and telemetry monitoring aspects of the Amine Swingbed experiment. These software components are the Swingbed Loader Computer Software Configuration Item...

Researchers at NASA's Marshall Space Flight Center have developed a cryogenic isolation valve that utilizes the upstream line pressure of cryogenic fluids for actuation. Previously, the use of cryogenic fluids for actuation systems had been too difficult to control and resulted in unsafe operating...

NASA Goddard Space Flight Center has developed the NOVA zero-leak, permanent isolation valve that helps prevent leaks in space propulsion systems with operating pressures less than or equal to 500 psia. The actuator is made from nitinol, a heat-activated, non-explosive, shape memory alloy and...

NASA's Marshall Space Flight Center has developed a device and method for blocking the flow of fluid from an open pipe. The device plugs, controls, and meters the flow of gases and liquids. Anchored with friction fittings, spikes, or explosively activated fasteners, the device...

NASA Marshall has developed a system for generating iodine vapor from solid iodine for use as a propellant in a Hall or ion thruster propulsion system. Xenon has generally been the preferred propellant for these spacecraft ion propulsion systems but more recently, iodine-based...
