In recent years scientists have investigated a series of new methods for non-rocket space launch, which promise to revolutionize space launches and flight. Particularly in the current political climate new, cheaper, and more ‘fuel efficient’ methods are being investigated. Such new methods include the gas tube method, cable accelerators, tether launch systems, space elevators, solar and magnetic sails, circle launcher space keepers and more. The author of Non-Rocket Space Launch and Flight brings a vast amount of experience to the topic, having worked as a engineer, designer, project director and researcher at key institutes including NASA and the US Air Force. Explores all the new non-rocket space launch methods, and compares them with each other and traditional rockets Investigates the unifying principles of the different systems and shows how to select the best design suited to the mission Author brings together technical and theoretical expertise from both industry and academia

Michel van Pelt explains for the first time the principle of space tethers: what they are and how they can be used in space. He introduces non-technical space enthusiasts to the various possibilities and feasibility of space tethers including the technological challenges and potential benefits. He illustrates how, because of their inherent simplicity, space tethers have the potential to make space travel much cheaper, while ongoing advances in tether material technology may make even seemingly far-fetched ideas a reality in the not too distant future.

This fascinating collection of traditional metaphors and figures of speech, groups expressions according to theme. The second edition includes over 1,500 new entries, more information on first known usages, a new introduction and two expanded indexes. It will appeal to those interested in cultural history and the English language.

This book offers a comprehensive overview of recently developed space multi-tethers, such as maneuverable space tethered nets and space tethered formation. For each application, it provides detailed derivatives to describe and analyze the mathematical model of the system, and then discusses the design and proof of different control schemes for various problems. The dynamics modeling presented is based on Newton and Lagrangian mechanics, and the book also introduces Hamilton mechanics and Poincaré surface of section for dynamics analysis, and employs both centralized and distributed controllers to derive the formation question of the multi-tethered system. In addition to the equations and text, it includes 3D design drawings, schematic diagrams, control scheme blocks and tables to make it easy to understand. This book is intended for researchers and graduate students in the fields of astronautics, control science, and engineering.
