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.
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!
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
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.
"A towering epic to rank with Douglas Preston's Blasphemy and Michael Crichton's Prey... Pandemic drought, skyrocketing oil prices, dwindling energy supplies and wars of water scarcity threaten the planet. Only four people can prevent global chaos. Gary Morgan--a brilliant, renegade scientist is pilloried by the scientific community for his belief in a space elevator: a pillar to the sky, which he believes will make space flight fast, simple and affordable. Eva Morgan--a brilliant and beautiful scientist of Ukrainian descent, she has had a lifelong obsession to build a pillar to the sky, a vertiginous tower which would mine the power of the sun and supply humanity with cheap, limitless energy forever. Gunther Rothenberg--the ancient but revered rocket-scientist who labored at Peenemunda with von Braun to create the first rockets and continued on to build those of today. A legend, he has mentored Gary and Natalia for two decades, nurturing and encouraging their transcendent vision. Franklin Smith--the eccentric Silicon Valley billionaire who will champion their cause, wage war with Congress and government bureaucracy and most important, finance their herculean undertaking. This journey to the stars will not be easy--a tumultuous struggle filled with violence and heroism, love and death, spellbinding beauty and heartbreaking betrayal. The stakes could not be higher. Humanity's salvation will hang in the balance"--
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.
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.
