ThermaSat™ propulsion system uses water as a safe and non-explosive propellant, and which is unpressurized at liftoff. Utilizing solar thermal propulsion, the compact and efficient capacitor heats water to steam to produce high thrust and total impulse. The advanced optical system allows for the thermal capacitor to charge through solar power alone with no protruding concentrators or power draw from the main bus. Additional solar panels, body mounted to the ThermaSat, provide auxiliary heating of the thermal capacitor when not directly incident to sunlight to promote non-sun pointing operations. Additionally, a conductive insulative system or method can include a phase change material and an insulated thermal capacitor wrapped in an insulative material including an inner layer of a high temperature multi-layer insulation and an outer layer of low temperature multi-layer insulation and the outside of the outer layer is covered with a reflective material.
