Logsdon draws on more than 40 years of aerospace engineering experience and orbital mechanics study to introduce professionals and graduate students to the behavior and interaction of orbiting celestial bodies. He surveys the subject from early astronomers' investigations and theories such as Kepler's laws, to current control and propulsion systems, satellite payload optimization and constellation design, and orbital perturbations, paying particular attention to the curious movements of rockets and occasionally strange results of simple maneuvers. The text is well-illustrated with plenty of diagrams and uses imaginative analogies involving slides, balloons, and billiard balls.
