The authors take the reader through the history of the concept, technical design and economic practicalities of building an elevator to space, and, ultimately, the implications of what such a low cost transportation system would mean to society. Based on three years of NASA-funded studies and written for the technically literate layperson, Edwards and Westling discuss the recent technological advances that now make the space elevator feasible. They conclude by addressing the effects that the space elevator could have on mankind's future from communications and energy to colonizing space.
What is a space elevator? A space elevator is a physical connection from the surface of the Earth to a geostationary Earth orbit (GEO) above the Earth .35,786 km in altitude. Its center of mass is at the geostationary point such that it has a 24-hr orbit and stays over the same point above the equator as the Earth rotates on its axis. The vision is that a space elevator would be utilized as a transportation and utility system for moving people, payloads, power, and gases between the surface of the Earth and space. It makes the physical connection from Earth to space in the same way a bridge connects two cities across a body of water. The Earth to GEO space elevator is not feasible today, but could be an important concept for the future development of space in the latter part of the 21st century. It has the potential to provide mass transportation to space in the same way highways, railroads, power lines, and pipelines provide mass transportation across the Earth's surface. The low energy requirements for moving payloads up and down the elevator could make it possible to achieve cost to orbit
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.
The breakup of the Space Shuttle Columbia as it reentered Earth's atmosphere on February 1, 2003, reminded the public--and NASA--of the grave risks posed to spacecraft by everything from insulating foam to space debris. Here, Alan Tribble presents a singular, up-to-date account of a wide range of less conspicuous but no less consequential environmental effects that can damage or cause poor performance of orbiting spacecraft. Conveying a wealth of insight into the nature of the space environment and how spacecraft interact with it, he covers design modifications aimed at eliminating or reducing such environmental effects as solar absorptance increases caused by self-contamination, materials erosion by atomic oxygen, electrical discharges due to spacecraft charging, degradation of electrical circuits by radiation, and bombardment by micrometeorites. This book is unique in that it bridges the gap between studies of the space environment as performed by space physicists and spacecraft design engineering as practiced by aerospace engineers.
This book provides in-depth coverage of the latest research and development activities concerning innovative wind energy technologies intended to replace fossil fuels on an economical basis. A characteristic feature of the various conversion concepts discussed is the use of tethered flying devices to substantially reduce the material consumption per installed unit and to access wind energy at higher altitudes, where the wind is more consistent. The introductory chapter describes the emergence and economic dimension of airborne wind energy. Focusing on “Fundamentals, Modeling & Simulation”, Part I includes six contributions that describe quasi-steady as well as dynamic models and simulations of airborne wind energy systems or individual components. Shifting the spotlight to “Control, Optimization & Flight State Measurement”, Part II combines one chapter on measurement techniques with five chapters on control of kite and ground stations, and two chapters on optimization. Part III on “Concept Design & Analysis” includes three chapters that present and analyze novel harvesting concepts as well as two chapters on system component design. Part IV, which centers on “Implemented Concepts”, presents five chapters on established system concepts and one chapter about a subsystem for automatic launching and landing of kites. In closing, Part V focuses with four chapters on “Technology Deployment” related to market and financing strategies, as well as on regulation and the environment. The book builds on the success of the first volume “Airborne Wind Energy” (Springer, 2013), and offers a self-contained reference guide for researchers, scientists, professionals and students. The respective chapters were contributed by a broad variety of authors: academics, practicing engineers and inventors, all of whom are experts in their respective fields.
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.
An easy guide to the most exciting development in space travel since the rocket. Stripped of the technical jargon, this is a laymans guide to the breathtaking developments surrounding the space elevator: a plan to string a 100,000 km from Earth to space, revolutionising space access.

NAMED ONE OF THE BEST BOOKS OF THE YEAR BY The Washington Post • NPR • The Guardian • Kirkus Reviews • The fiction of multiple award–winning author China Miéville is powered by intelligence and imagination. Like George Saunders, Karen Russell, and David Mitchell, he pulls from a variety of genres with equal facility, employing the fantastic not to escape from reality but instead to interrogate it in provocative, unexpected ways. London awakes one morning to find itself besieged by a sky full of floating icebergs. Destroyed oil rigs, mysteriously reborn, clamber from the sea and onto the land, driven by an obscure purpose. An anatomy student cuts open a cadaver to discover impossibly intricate designs carved into a corpse’s bones—designs clearly present from birth, bearing mute testimony to . . . what? Of such concepts and unforgettable images are made the twenty-eight stories in this collection—many published here for the first time. By turns speculative, satirical, and heart-wrenching, fresh in form and language, and featuring a cast of damaged yet hopeful seekers who come face-to-face with the deep weirdness of the world—and at times the deeper weirdness of themselves—Three Moments of an Explosion is a fitting showcase for one of literature’s most original voices. Praise for Three Moments of an Explosion “China Miéville is dazzling. His latest collection of short stories, Three Moments of an Explosion, crowds virtuosity into every sentence.”—The New York Times “You can’t talk about [China] Miéville without using the word ‘brilliant.’ . . . His wit dazzles, his humour is lively, and the pure vitality of his imagination is astonishing.”—Ursula K. Le Guin, The Guardian “[A] gripping collection . . . Miéville expertly mixes science fiction, fantasy and surrealism. . . . Amid the longer stories are more cerebral, poetic flash pieces that will haunt the reader beyond the pages of this exceptional book.”—The Washington Post “The stories shine . . . with a winking brilliance.”—The Seattle Times “Mind-bending excursions into the fantastic.”—NPR “Bradbury meets Borges, with Lovecraft gibbering tumultuously just out of hearing.”—Kirkus Reviews (starred review) “Three Moments of an Explosion is a book filled with fabulous oddities.”—Entertainment Weekly “Miéville moves effortlessly among realism, fantasy, and surrealism. . . . His characters, whether ordinary witnesses to extraordinary events or lunatics operating out of inexplicable compulsions, are invariably well drawn and compelling.”—Publishers Weekly (starred review)
