“The book under review provides a comprehensive treatment of optimal space flight, covering most of the problems and main results that have appeared in the published literature. The book is a welcome addition in that it provides a self-contained introduction to the field that should be of broad interest to applied mathematicians, physicists and engineers.” (N. Harris McClamroch, Mathematical Reviews, July, 2019) “This book is designed to be used as a textbook in a course on optimal space flight at the graduate and senior undergraduate levels, but it is very useful also for all control scientists and control engineers.” (Clementina Mladenova, zbMath 1412.49002, 2019)
