In the last year, the International Space Elevator Consortium assessed that basic technological needs can be met with current capabilities: and, each segment of the Space Elevator Transportation System is ready for engineering validation. Because of the availability of a new material as a potential Space Elevator tether, the community strongly believes that a Space Elevator will be initiated in the near term. Included in the book is a series of appendices that are tremendous references to the status of the space elevator today. Included are a lexicon of space elevator terms, over 750 references in the bibliography, short descriptions of eight ISEC year-long studies and two IAA 4-year studies on space elevators, as well as a summary of over 20 Architectural Notes covering the development of space elevator technologies.

The study team took on the challenge of expanding the "body of knowledge" pertaining to the Apex and Geosynchronous elements of the Space Elevator. A special effort was made to describe the elements in the context of an entire Space Elevator. The report complements and expands earlier ISEC Space Elevator reports on the Climber, Operations Concept, Architectures & Roadmaps, and Earth Port. To do so, we have established; 1.A robust set of definitions within the Geosynchronous and Apex Regions, and 2.The Strategic Approach to Architectural Development of a Space Elevator

This history of SAFSP is dedicated to all those men and women who fought the Cold War, in silence - from above. No organization is better at gathering overhead intelligence than the U.S. National Reconnaissance Office (NRO). Today's NRO grew out of 3 organizations: AF, CIA, and Navy. The AF office for satellite reconnaissance was called the Secretary of Air Force's Office of Special Projects [SAFSP]. This monograph describes the birth of Air Force satellite reconnaissance. When SAFSP was created in response to Presidential recognition of a national imperative, 4 tenets captured the sense of urgency: direct access to national leadership, covert management/operations, highest national priority, and rapid procurement. In addition, 3 management principles led to SAFSP's success over 30+ years of providing reconnaissance intelligence: strong dedication to mission, empowerment at all levels, and reporting by exception.

The International Space Elevator Consortium has created this position paper as a recognition that the space debris problem is an engineering one and can be mitigate. The question: "Will space debris be a show stopper for space elevators?" is answered emphatically - NO! The mitigation concepts presented change the issue from a perceived problem to an engineering concern; but, by no means is it a significant threat. This pamphlet illustrates how the development office for a future space elevator can attack this problem, predict probabilities of collision, and convert the concern into another manageable engineering problem.

The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future. The following are a few of the conclusions: * The study used the concept of "constant power" as a baseline because of its ability to lower design requirements on the tether climber. * The mass breakout of 6 MT for a climber and 14 MT for customer payloads seems feasible. The estimate is that with a travel time of one week to GEO seven tether climbers can be on a tether simultaneously. * The communication architecture should be integrated into the space elevator infrastructure and nodal layout. * Solar power, as the sole source, appears achievable. * The use of laser power as the sole source also seems achievable.

While the development of Space Elevator tethers and climbers is a daunting task, their operation will leverage 50 years of satellite operations. This leads to the conclusion: Operations for a Space Elevator Have NO Showstoppers Have Reasonable Costs Meet the Challenges i?
