Long considered to be a classic text in the field,Spacecraft Systems Engineering provides readers with comprehensive coverage of the design of spacecraft and the implementation of space missions across a wide spectrum of space applications and space science. The new Fifth Edition has been updated to reflect the latest developments of the past decade while retaining the overall structure and breadth of coverage that is already widely respected by students, researchers, and practicing engineers, Spacecraft Systems Engineering covers the basics of everything from spacecraft dynamics, celestial mechanics, and propulsion to mission analysis, power systems, and communications. The Fifth Edition includes the most current information on the effect that the space environment has on systems design, including more recent rocket data, updated solar cycles, and updated magnetic models, charging models and radiation environment models. Throughout the book, updated content offers state-of-the-art examples in areas like remote sensing, new forms of manufacture like 3D printing and robotic assembly in space, "green" propulsion, the impact of CubeSats/SmallSats, and new developments in active space debris removal and disposal techniques. Special emphasis is placed on the new role of private enterprise in space, the way that new, lower-cost launch capabilities and the latest launch vehicles that are transforming the industry, and explanations of the regulatory frameworks under which these activities take place. New example missions have also been added to illustrate emerging activities like satellite constellation maintenance, on-orbit assembly for space based solar power, biosecurity for planetary missions, and "all-electric spacecraft" maneuvers.
