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 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 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.

What Is Space Elevator One concept for a transportation system that would link planets to space is called a space elevator. A cable that is attached to the surface and extends into space would be the primary component of this system. Without the need for huge rockets, the architecture of the system would enable vehicles to ascend the cable from the surface of a planetary body, such as the surface of the Earth, and enter orbit directly. Because of the enormous weight, a space elevator based on Earth could not simply be a tall tower supported from below. Instead, it would consist of a cable with one end attached to the surface near the equator and the other end attached to a counterweight in space beyond geostationary orbit. This would allow the elevator to move between the surface and the counterweight. The opposing forces of gravity, which is stronger at the lower end, and the upward centrifugal force, which is stronger at the upper end, would result in the cable being held up, under tension, and stationary over a single position on Earth. Gravity is stronger at the lower end, while the upward centrifugal force is stronger at the upper end. After the tether has been deployed, climbers will be able to use mechanical methods to repeatedly ascend and descend the tether in order to release their payload into and out of orbit.

The optimized conceptual engineering design of a space station tethered elevator is presented. The elevator is an unmanned mobile structure which operates on a ten kilometer tether spanning the distance between the Space Station and a tethered platform. Elevator capabilities include providing access to residual gravity levels, remote servicing, and transportation to any point along a tether. The potential uses, parameters, and evolution of the spacecraft design are discussed. Engineering development of the tethered elevator is the result of work conducted in the following areas: structural configurations; robotics, drive mechanisms; and power generation and transmission systems. The structural configuration of the elevator is presented. The structure supports, houses, and protects all systems on board the elevator. The implementation of robotics on board the elevator is discussed. Elevator robotics allow for the deployment, retrieval, and manipulation of tethered objects. Robotic manipulators also aid in hooking the elevator on a tether. Critical to the operation of the tethered elevator is the design of its drive mechanisms, which are discussed. Two drivers, located internal to the elevator, propel the vehicle along a tether. These modular components consist of endless toothed belts, shunt-wound motors, regenerative power braking, and computer controlled linear actuators. The designs of self-sufficient power generation and transmission systems are reviewed. Thorough research indicates all components of the elevator will operate under power provided by fuel cells. The fuel cell systems will power the vehicle at seven kilowatts continuously and twelve kilowatts maximally. A set of secondary fuel cells provides redundancy in the unlikely event of a primary system failure. Power storage exists in the form of Nickel-Hydrogen batteries capable of powering the elevator under maximum loads. Anderson, Loren A.

ABOUT THE BOOK The Orbital Space Elevator Project is an ongoing international endeavour to create a ground to space mechanical system that would allow man and materials to be transported into space without the use of rockets or jet propulsion. Using a laser based system, a transport vehicle would be propelled into space along a super material with over 100 times the strength of steal. This system would allow man to travel into space with as much ease, frequency, and cost as little as shipping a package to a different continent. I will soon explain to you the nearly unimaginable possibilities of a this system and how it can alter mankind's position in the universe. I have studied matters of physics at length and can be rightfully labeled a theoretical science enthusiast. In order to approach this topic with the correct frame of mind, I encourage you suspend disbelief. One cannot grasp the intention of theoretical science by applying the current limitations of human ingenuity. The whole purpose of the word “theoretical” is to give notice of something that is within the grasp of human capability but has yet to be realized by our ingenuity. EXCERPT FROM THE BOOK The orbital station would sit in geostationary orbit and be the terminal point of the climber, or car, that would bring people and objects up into space. The propulsion method of the climber itself is another area of interest and concern. At the yearly Climber (Power Beaming) Competition and Tether Strength Competition, scientists from all over the world assemble and bring in prototypes of their climber systems in hopes of winning the $500,000 prize. In 2009, a Seattle-based group, LaserMotive, won $900,000 at NASA’s Centennial Challange when their laser powered robot climbed a 900-meter-long cable, suspended from a helicopter – in 7.5 minutes. Proposed methods vary widely with most stemming from a manner of laser driven propulsion, not dissimilar from the kind used in your laser DVD player. Others have proposed a track system akin to those of high speed magnetic railway lines. While a considerable portion of laser research is done by the military, they have said that they are very open to the idea of using lasers in more civilian, non-military capacities. The laser’s power generation is proposed to be driven by varied sources such as solar rays bounced off enormous mirrors, to heat based lasers. Depending on the method of propulsion, the estimated travel time between Earth and the orbital station could be anywhere from five hours to a seven and a half days... Buy a copy to keep reading!
