This graduate textbook on optimal spacecraft trajectories demonstrates the theory and applications of using the minimum amount of propellant possible to reach a target destination. The author aims to produce the only comprehensive treatment of various aspects of this topic. It includes problems at the ends of the chapters and some of the appendices. But it is also suitable as a scholarly reference book as it includes recent research from the author and his colleagues.
