Spacecraft thrusters capable of dual-mode operation, and a method of applying propulsion to a spacecraft using a dual-mode thruster are provided. In one embodiment, the thrusters of the current invention can operate as a chemical motor to provide high thrust and low propellant exhaust velocity to achieve fast maneuverability, or as an electric propulsion thruster to provide low thrust and high exhaust velocity to perform maneuvers with a minimal amount of propellant.
What is claimed is: 1. A dual-mode spacecraft thruster comprising: a thruster body containing a solid propellant, and having a combustion region adjacent to said solid propellant and a nozzle region adjacent to said combustion region, wherein the propellant ignites to produce a thrust only with the application of electrical power to the solid propellant; a source of electrical power in electrical communication with said solid propellant through a primary electrode, said primary electrode being disposed within the combustion region of the thruster body; ...
