_Orbital Mechanics for Engineering Students, Fourth Edition,_ is a key text for students of aerospace engineering. While this latest edition has been updated with new content and included sample problems, it also retains its teach-by-example approach that emphasizes analytical procedures, computer-implemented algorithms, and the most comprehensive support package available, including fully worked solutions, PPT lecture slides, and animations of selected topics. Highly illustrated and fully supported with downloadable MATLAB algorithms for project and practical work, this book provides all the tools needed to fully understand the subject. * Provides a new chapter on the circular restricted 3-body problem, including low-energy trajectories * Presents the latest on interplanetary mission design, including non-Hohmann transfers and lunar missions * Includes new and revised examples and sample problems
