The second edition of "Space Mission Analysis and Design" continues the tradition of emphasizing the process of mission design established by the first edition. Process tables are now included for all elements of the design activity. The quick-reference tables of important mission design parameters have been expanded to six pages on the inside rear cover. Numerous data tables have been expanded and updated, including space computers and a new presentation of satellite lifetimes. New sections have been added on defining the overall mission concept, subject trades, guidance and navigation, and applying the mission analysis and design process to reduce cost and risk in later programme stages. The material on mission analysis, space payloads, spacecraft subsystems, and launch systems has been substantially revised. This book remains an invaluable tool for the concept exploration process and is required reading for anyone involved in this process for unmanned space missions. This book is intended for professionals and students in astronautics and space science, aerospace engineers and managers, and scientists involved with space experiments.It is also suitable as a textbook in space mission analysis and design, or as supplementary reading for courses in virtually any area of space technology.

Reducing Space Mission Cost is the first complete treatment of the technology, process, and problems in the most critical areas of modern spaceflight. The demand to reduce cost is unrelenting. This pioneering book addresses all aspects of this problem, including: * Technology and processes for reducing cost * Cost reduction in mission engineering, spacecraft design, manufacture, launch, and operations * Implementation methods and problems * The price of reducing cost *10 detailed case studies of what works in practice in: * Science missions * Interplanetary probes * Communications spacecraft * Test and Applications missions Beginning on the inside front cover, this book provides real cost data on a variety of missions, systems, and subsystems. According to the authors: 'Reducing mission cost is hard enough if you know what the real costs are, and virtually impossible if you don't.' This book challenges traditional methods, yet recognizes that all space programs are run to minimize cost within the rules under which they are built and flown.It provides practical recipes for reducing cost in both new and ongoing missions and discusses what works, what government can do to help, and what methods intended to reduce cost may be counterproductive and unintentionally increase cost. As shown on the inside rear cover, the case studies described in the book have reduced total mission cost by 80% to more than 90% with respect to projections by traditional cost methods. This book is a follow-on to the now standard text and reference, Space Mission Analysis and Design, also edited by Drs. Wertz and Larson. It is required reading for professionals, students, and managers in astronautics or space sciences and managers or scientists involved in space experiments. This book shows that reducing space mission cost, without reducing reliability, is as possible as it is important for the future of space exploration.
