Space Tethers and Space Elevators


Book Description

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.




Rescue Mode


Book Description

Gritty and scientifically accurate science fiction adventure from New York Times best-selling author Ben Bova and NASA space scientist Les Johnson. The first human mission to Mars meets with near-disaster when a meteoroid strikes the spacecraft, almost destroying it. The ship is too far from Earth to simply turn around and return home. The eight-person crew must ride their crippled ship to Mars while they desperately struggle to survive. On Earth, powerful political forces that oppose human spaceflight try to use the accident as proof that sending humans into space is too dangerous to continue. The whole human space flight program hangs in the balance. And if the astronauts can’t nurse their ship to Mars and back, the voyagers will become either the first Martian colonists—or the first humans to perish on another planet. At the publisher's request, this title is sold without DRM (Digital Rights Management). About Mars, Inc.: "The Hugo winner returns to his most popular subject: the quest for Mars."—Publishers Weekly About the award winning novels of Ben Bova: “Technically accurate and absorbing . . .”—Kirkus “[Bova is] the science fiction author who will have the greatest effect on the world.”—Ray Bradbury “A masterful storyteller”—Vector “Gives a good read while turning your eyes to what might be in the not so distant future, just like Clarke and Asimov used to do so well.”—SFX

Space Elevators


Book Description

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




Space Elevators: A History


Book Description

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.




Dynamics of Tethered Satellite Systems


Book Description

Aimed at engineering students and professionals working in the field of mechanics of space flight, this book examines space tether systems – one of the most forward-thinking directions of modern astronautics. The main advantage of this technology is the simplicity, profitability and ecological compatibility: space tethers allow the execution of various manoeuvers in orbit without costs of jet fuel due to the use of gravitational and electromagnetic fields of the Earth. This book will acquaint the reader with the modern state of the space tether’s dynamics, with specific attention on the research projects of the nearest decades. This book presents the most effective mathematical models and the methods used for the analysis and prediction of space tether systems’ motion; attention is also given to the influence of the tether on spacecraft’s motion, to emergencies and chaotic modes. Written by highly qualified experts with practical experience in both the fields of mechanics of space flight, and in the teaching Contains detailed descriptions of mathematical models and methods, and their features, that allow the application of the material of the book to the decision of concrete practical tasks New approaches to the decision of problems of space flight mechanics are offered, and new problems are posed




The Space Elevator


Book Description

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.




Rocketing Into the Future


Book Description

This book describes the technology, history, and future of rocket planes. Michel van Pelt journies into this exciting world, examining the exotic concepts and actual flying vehicles that have been devised over the last hundred years. He recounts the history of rocket airplanes, from the early pioneers who attached simple rockets onto their wooden glider airplanes to the modern world of high-tech research vehicles. The author visits museums where rare examples of early rocket planes are kept and modern laboratories where future spaceplanes are being developed. He explains the technology in an easily understandable way, describing the various types of rocket airplanes and looking at the possibilities for the future. Michel van Pelt considers future spaceplanes, presenting various modern concepts and developments. He describes the development from cutting edge research via demonstrator vehicles to operational use. He also evaluates the replacement of the Space Shuttle with a seemingly old-fashioned capsule system, the parallel developments in suborbital spaceplanes such as SpaceShipOne and SpaceShipTwo, piloted versus automatic flight, and related developments in airliners and military aircraft.




Dream Missions


Book Description

This book takes the reader on a journey through the history of extremely ambitious, large and complex space missions that never happened. What were the dreams and expectations of the visionaries behind these plans, and why were they not successful in bringing their projects to reality thus far? As spaceflight development progressed, new technologies and ideas led to pushing the boundaries of engineering and technology though still grounded in real scientific possibilities. Examples are space colonies, nuclear-propelled interplanetary spacecraft, space telescopes consisting of multiple satellites and canon launch systems. Each project described in this book says something about the dreams and expectations of their time, and their demise was often linked to an important change in the cultural, political and social state of the world. For each mission or spacecraft concept, the following will be covered: • Description of the design. • Overview of the history of the concept and the people involved. • Why it was never developed and flown • What if the mission was actually carried out – consequences, further developments, etc.
