This is a book that contains road maps for the thought processes and the tools required to design future systems for economical and successful operations in space. It describes generating operational
and logistics requirements using appropriate source data, trade studies, and analysis techniques in a system engineering process based on terrestrial analogs. It helps readers identify the intrinsic requirements and
formulate the derived requirements that influence manned and unmanned system designs for extraterrestrial operations. This volume uses case studies to describe missions to several Earth orbits, the Moon, and Mars in
order to illustrate the diverse factors that must be considered for operating in these environments. These cases are not definitive answers to each mission, but illustrate approaches, based on sound system engineering
principles, that can bring closure to such efforts. This book can be a valuable tool for civilian, government, and military managers and engineers involved with the development of future space systems. It can also serve
as a supplemental text for aerospace management, systems engineering, and logistic engineering courses.
