US Patent 11203447 Propulsion system for space vehicles

An electric propulsion module coupled to a spacecraft capable of providing thrust at a level required for multi-burn orbit transfer is disclosed herein. The electric propulsion system includes an electric propulsion thruster, a propellant tank and an energy storage device. In one form the energy storage device is a battery operable to provide sufficient power to maneuver the spacecraft quickly to avoid space debris and/or move to a different orbit through a multi-burn thrust procedure.
