Micropropulsion is an enabling technology for microspacecraft operations. This work reports on the state of the art in micropropulsion concepts and activities, with survey papers, and sections on electrothermal, electrostatic, and electromagnetic thrusters and components. Topics include system considerations and design options, predicted performance and systems analysis of the free molecule micro-reistojet, and very low-power arcjets. Micci teaches aerospace engineering at Pennsylvania State University. Ketsdever is on the research staff at the Air Force Research Laboratory's Propulsion Directorate. Annotation c.
