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.

This study was designed to take the concept of Space Elevators and answer some questions relative to space debris. The team built upon the 2010 study on the topic and addressed many other issues to include: - The probabilities of orbital conjunctions between a space elevator and debris in Low Earth Orbit, Geo Earth Orbit, and Medium Earth Orbit. - The growth rate of space debris as it threatens operational space elevator (2010, 2019, 2030)? - Mitigation of risk for the space community through design, policies, operations, and lowering the threat. This year's study topic focused upon calculations for potential conjunction probabilities from densities of debris for 2010, 2019, and 2030. ""Space debris mitigation is an engineering problem with definable quantities such as density of debris and lengths/widths of targets. With proper knowledge and good operational procedures, the threat of space debris is not a show-stopper. However, mitigation approaches must be accepted and implemented robustly.""

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.

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

Under the editorship of David Raitt, this timely book brings together for the first time the record of people, places, developments and activities, in fiction and in fact, of the space elevator - a 100,000 km long, meter wide, ribbon reaching up from the Earth and into space along which robotic climbers that will travel to bring payloads into orbit at a fraction of the price of rocket launches. The chapters in the book cover the early pioneers who dreamt up the concept initially some 120 years ago; the work of modern day scientists and engineers who have developed the concept into doable plans; how the concept has been portrayed in novels, films and art; the conferences at which interested people could present and discuss their work and ideas; the global community that has grown up around space elevators and the competition challenges that have been held; and what the future may hold.

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.

The International Space Elevator Consortium has conducted a year-long study addressing the issues associated with how to start the development of space elevators. This report is the result. The process for developing an architecture for a new system of systems has many steps. Each step leads to a technological roadmap leading to a mature engineering structure. Five segment roadmaps are developed: Tether Climber, Tether, Marine Node, Apex Anchor and Headquarters Primary Operations Center. The initial set of challenges for each segment is established. These will fuel a series of demonstrations pushing the development team to Culminating Demo's that resolves all those challenges. Then, Implementation Plans will be written and executed resulting in an Initial Operational Capability (IOC). This study is an excellent step in the ongoing analysis of the technological feasibility of space elevators.

The International Space Elevator Consortium conducted a year-long study on the development of a space elevator Earth Port. This report addresses the functional requirements and missions leading to a mature engineering complex along the equator. The report represents the culmination of efforts by multiple contributors describing the functions and operations of the Earth Port and how it interacts with other space elevator nodes. The challenge was to bring in a fresh perspective on an Earth Port by leveraging experts in many fields beyond those normally associated with space elevators. As a result of the contributions from a variety of professional backgrounds, this study should reflect a more realistic perspective of the activities at the Earth Port of a future space elevator.

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
