Applied Space Systems Engineering is the 17th book produced by the US Air Force Academyβs Space Technology Series team. The purpose of Applied Space Systems Engineering (ASSE) is to provide inspiration, processes, approaches, tools, and information for systems engineers that are leading the way in complex aerospace system design, development, and operation. An extensive author and editor team created this book based on a complete and rigorous set of systems engineer competencies rooted in the experiences and philosophies of seasoned space systems engineers from across the community. The βbest of the bestβ performing system engineers have contributed their wealth of experience, successful tools and approaches, and lessons learned to this project. This book presents the βhow-toβ necessary to βsystems engineerβ complex aerospace-related projects, along with information to help the aspiring or current systems engineer achieve a higher level of understanding and performance. Itβs geared to practitioners as they work through projects, but may also serve as a primary text or reference for graduate-level courses and development programs. Many aerospace-related case studies, examples, and lessons learned are spread throughout ASSE to provide historical insights and practical applications. A companion text, Applied Project Management for Space Systems, is also available.
