This book was released on 2004-09-06 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is known that large asteroids and comets can collide with the Earth with severe consequences. Although the chances of a collision in a person's lifetime are small, collisions are a random process and could occur at any time. This book collects the latest thoughts and ideas of scientists concerned with mitigating the threat of hazardous asteroids and comets. It reviews current knowledge of the population of potential colliders, including their numbers, locations, orbits, and how warning times might be improved. The structural properties and composition of their interiors and surfaces are reviewed, and their orbital response to the application of pulses of energy is discussed. Difficulties of operating in space near, or on the surface of, very low mass objects are examined. The book concludes with a discussion of the problems faced in communicating the nature of the impact hazard to the public.

Download or read book Hazards Due to Comets and Asteroids written by Tom Gehrels and published by University of Arizona Press. This book was released on 2021-11-30 with total page 1317 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1993, the U.S. Department of Defense declassified information dealing with frequent explosions in the upper atmosphere caused by meteoric impact. It is estimated that impacts have occurred of a magnitude equivalent to the atomic bomb detonated at Hiroshima. Not all such space voyagers meet their end in the atmosphere, however; huge craters attest to the bombardment of earth over millions of years, and a major impact may have resulted in the extinction of dinosaurs. An impact in Siberia near the beginning of this century proves that such events are not confined to geologic time. Hazards Due to Comets and Asteroids marks a significant step in the attempt to come to grips with the threats posed by such phenomena. It brings together more than one hundred scientists from around the world, who draw on observational and theoretical research to focus on the technical problems related to all aspects of dealing with these hazards: searching for and identifying hazardous comets and asteroids; describing their statistics and characteristics; intercepting and altering the orbits of dangerous objects; and applying existent technologies—rocket boosters, rendezvous and soft-landing techniques, instrumentation—to such missions. The book considers defensive options for diverting or disrupting an approaching body, including solar sails, kinetic-energy impacts, nuclear explosives, robotic mass drivers, and various propulsion systems. A cataclysmic impact posing a threat to life on Earth is a possibility that tomorrow's technology is capable of averting. This book examines in depth the reality of the threat and proposes practical measures that can be initiated now should we ever need to deal with it.

Download or read book On to the Asteroid written by Travis S. Taylor and published by Baen Books. This book was released on 2016-08-02 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: LOOMING DESTRUCTION FROM SPACE! It's the beginning of a new golden age of space exploration. Finally, humanity is taking the commercialization of space to the next level—mining asteroids. The new gold rush of the commercial space era has begun. Another commercial venture, an attempt to put a hotel on the Moon, is seeking the space tourism gold of the ultra wealthy. And it seems as if the dream of finally sending people to Mars is finally going to happen using a ship propelled by a powerful nuclear rocket. But space travel isn’t cut and dry, and there is nothing routine about it. In order to mine an asteroid the goal is to bring it closer to Earth, but orbital mechanics are tricky and close to Earth proves to be far too close for comfort—with looming destruction from space about to become a grim reality. Now astronauts, scientists, engineers, and people in all the burgeoning space businesses must team together to stop the asteroid before it is too late for humanity and the planet it calls home.

Download or read book Harvesting Space for a Greener Earth written by Greg Matloff and published by Springer Science & Business Media. This book was released on 2014-04-07 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: What was our planet like in years past? How has our civilization affected Earth and its ecology? Harvesting Space for a Greener Planet, the Second Edition of Paradise Regained: The Regreening of the Earth, begins by discussing these questions, and then generates a scenario for the restoration of Earth. It introduces new and innovative ideas on how we could use the Solar System and its resources for terrestrial benefit. The environmental challenges that face us today cannot be resolved by conservation and current technologies alone. Harvesting Space highlights the risk of humankind’s future extinction from environmental degradation. Population growth, global climate change, and maintaining sustainability of habitats for wildlife are all considered, among other issues. Rather than losing heart, we need to realize that the solutions to these problems lie in being good stewards of the planet and in the development of space. Not only will the solutions offered here avert a crisis, they will also provide the basis for continued technological and societal progress. Tapping the resources of near-Earth asteroids will lead to methods of diverting those asteroids that threaten Earth. Space-based terrestrial power generation systems will work synergistically with Earth-based conservation. This book needs to be read urgently and widely, if we are to save ourselves from environmental disaster, reduce the risk of catastrophic cosmic impacts, and build a prosperous and sustainable future for all the creatures of Earth.

Download or read book Space Systems and Sustainability written by Joseph N. Pelton and published by Springer Nature. This book was released on 2021-08-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his latest book, space scientist, futurist, and educator Joseph N. Pelton explores a dozen ways that Planet Earth is at “existential” risk, along with the many ways that space systems, data analytics, and advanced networking systems can help us cope with these global challenges. The chapters examine in a straightforward way how satellite systems and technol- ogy can drastically transform fields such as pandemic tracking and global medical responses, cosmic hazard monitoring, nuclear energy and waste disposal, water and land pollution, tele-education/telemedicine, and military conflict. Such examples show how orbiting smart systems will play an ever more vital role in our vulnerable modern world, allowing us to monitor, track, and respond to mounting problems of the 21st century. Dr. Pelton takes a broad view, probing the social, economic, and regulatory factors that are crucial to creating a more sustainable “Spaceship Earth.” This book is a call to action, promoting more organized international collaboration and investment in space technologies that can enable global change.

Download or read book ATOM Second Edition written by Kartik Gada and published by Business Expert Press. This book was released on 2020-12-29 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we will explore how the accelerating pace and diffusion of technological change has taken control of an ever-growing fraction of the world economy. This fraction is being assimilated into a different set of economic fundamentals, such as the rapid and exponential price deflation inherent to technology. The effect of this was insignificant until recently, but is now beginning to create conspicuous distortions in many economic metrics, and is just years from being the dominant force across the entire economy. In response to technological deflation, the central banks of the world will have to create new money in perpetuity, increasing the stream at an exponentially rising rate much higher than is currently assumed. This now-permanent need for monetary expansion, if embraced, can fund government spending more directly. This in turn creates a very robust, dynamic, and efficient safety net for citizens, while simultaneously reducing and even eliminating most forms of taxation by 2025–30. Failure to recognize that technological deflation mandates permanent and ever-rising central bank monetary expansion that can and should gradually become the primary source of government spending could result in countries falling behind more enlightened countries in a very short time. The nature of current worldwide technology is to link various disruptions with each other, consume monetary liquidity to generate deflation, and lower the effective prices of most goods and services over time. Therefore, the entirety of worldwide technology has to be seen as a holistic economic entity, and can be defined as the ‘Accelerating TechnOnomic Medium’, or ‘ATOM’ .

Download or read book Space Debris and Other Threats from Outer Space written by Joseph N. Pelton and published by Springer Science & Business Media. This book was released on 2013-03-27 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mounting problem of space debris in low earth orbit and its threat to the operation of application satellites has been increasingly recognized as space activities increase. The efforts of the Inter Agency Space Debris Coordinating Committee (IADC) and UN COPUS have now led to international guidelines to mitigate the creation of new debris. This book discusses the technical studies being developed for active removal processes and otherwise mitigating problems of space debris, particularly in low earth orbit. This book also considers threats to space systems and the Earth that comes from natural causes such as asteroids, coronal mass ejections, and radiation. After more than half a century of space applications and explorations, the time has come to consider ways to provide sustainability for long-term space activities.

When Commanders Jim Atkins and Ali Mukbar have the chance to join a Scientific Expedition to the distant Extar System where two Comets are due to impact a planet. No one expected to encounter dangerous Life-forms there. Kharloriasn Biologists had thought the System too young for these to have developed. But even more deadly than those were the Warriors of Canergorm, temporary allies of the Dagar Confederation at war with the Kharlorian Empire. At first it was a Contract to take some Dagar scientists to study the Comet Impact. But finding Ali and Jim were going, Jano Dagar promised further payment for eliminating Ali and Jim. When the Canergorms immobilised all the Kharlorian Saucers and captured Ali and others including Princess Clyra Vergred, they hoped to getr still more. With Jim and just a few scientists still free they are their only hope.

Download or read book Cartographies of Danger written by Mark Monmonier and published by University of Chicago Press. This book was released on 2008-04-15 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: No place is perfectly safe, but some places are more dangerous than others. Whether we live on a floodplain or in "Tornado Alley," near a nuclear facility or in a neighborhood poorly lit at night, we all co-exist uneasily with natural and man-made hazards. As Mark Monmonier shows in this entertaining and immensely informative book, maps can tell us a lot about where we can anticipate certain hazards, but they can also be dangerously misleading. California, for example, takes earthquakes seriously, with a comprehensive program of seismic mapping, whereas Washington has been comparatively lax about earthquakes in Puget Sound. But as the Northridge earthquake in January 1994 demonstrated all too clearly to Californians, even reliable seismic-hazard maps can deceive anyone who misinterprets "known fault-lines" as the only places vulnerable to earthquakes. Important as it is to predict and prepare for catastrophic natural hazards, more subtle and persistent phenomena such as pollution and crime also pose serious dangers that we have to cope with on a daily basis. Hazard-zone maps highlight these more insidious hazards and raise awareness about them among planners, local officials, and the public. With the help of many maps illustrating examples from all corners of the United States, Monmonier demonstrates how hazard mapping reflects not just scientific understanding of hazards but also perceptions of risk and how risk can be reduced. Whether you live on a faultline or a coastline, near a toxic waste dump or an EMF-generating power line, you ignore this book's plain-language advice on geographic hazards and how to avoid them at your own peril. "No one should buy a home, rent an apartment, or even drink the local water without having read this fascinating cartographic alert on the dangers that lurk in our everyday lives. . . . Who has not asked where it is safe to live? Cartographies of Danger provides the answer."—H. J. de Blij, NBC News "Even if you're not interested in maps, you're almost certainly interested in hazards. And this book is one of the best places I've seen to learn about them in a highly entertaining and informative fashion."—John Casti, New Scientist

Download or read book Why Geology Matters written by J. D. Macdougall and published by Univ of California Press. This book was released on 2011-05-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic dust, climate change, tsunamis, earthquakes—geoscience explores phenomena that profoundly affect our lives. But more than that, as Doug Macdougall makes clear, the science also provides important clues to the future of the planet. In an entertaining and accessibly written narrative, Macdougall gives an overview of Earth’s astonishing history based on information extracted from rocks, ice cores, and other natural archives. He explores such questions as: What is the risk of an asteroid striking Earth? Why does the temperature of the ocean millions of years ago matter today? How are efforts to predict earthquakes progressing? Macdougall also explains the legacy of greenhouse gases from Earth’s past and shows how that legacy shapes our understanding of today’s human-caused climate change. We find that geoscience in fact illuminates many of today’s most pressing issues—the availability of energy, access to fresh water, sustainable agriculture, maintaining biodiversity—and we discover how, by applying new technologies and ideas, we can use it to prepare for the future.

Available in PDF, EPUB and Kindle. Book excerpt: From the depths of space: total destruction! The alien fleet orbited Penum IV and used colorful incinerating death rays on the planet rotating below. When the inhabitants of the globe were annihilated and everything left worth pillaging stowed on black-hulled plunder ships, the fleet moved on to the next inhabited human world, unopposed except by… The warship Preceptor, commanded by Pier Norlin, a junior officer on a ship with only a skeleton crew. The ship lacks proper armament, the crew is mismatched and fighting among themselves--and the mission is not sanctioned by the Empire. For Norlin, these are only small obstacles to be ignored. He is on a personal mission of revenge against the aliens until… Command of the Preceptor is given to the genetically enhanced superman, Pavel Pensky. Pensky is brilliant—and quite insane. Will his daring schemes bring victory against the aliens or deliver rainbow death to Norlin and the Preceptor's crew?
