Space Elevators: an Assessment of the Technological Feasibility and the Way Forward, published in 2013, 349 pages. This book addresses the simple and complex issues that have been identified through the development of space elevator concepts over the last decade. The report begins with a summary of those ideas in Edwards’ and Westling’s book The Space Elevator (2003). Out of these beginnings has risen a worldwide cadre focused upon their areas of expertise as applied to space elevator development and operational infrastructure. The report answers some basic questions about the feasibility of a space elevator infrastructure. A preview of the main questions and answers shows the depth and breadth of this Cosmic Study: Why a space elevator? Can it be done? How would all the elements fit together to create a system of systems? What are the technical feasibility of each major space elevator element?
