Book Synopsis Hazards Due to Comets and Asteroids by : Tom Gehrels
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 1994 with total page 1340 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.
Book Synopsis Cartographies of Danger by : Mark Monmonier
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

Book Synopsis Asteroids III by : William Frederick Bottke
Download or read book Asteroids III written by William Frederick Bottke and published by University of Arizona Press. This book was released on 2002-01-01 with total page 818 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two hundred years after the first asteroid was discovered, asteroids can no longer be considered mere points of light in the sky. Spacecraft missions, advanced Earth-based observation techniques, and state-of-the-art numerical models are continually revealing the detailed shapes, structures, geological properties, and orbital characteristics of these smaller denizens of our solar system. This volume brings together the latest information obtained by spacecraft combined with astronomical observations and theoretical modeling, to present our best current understanding of asteroids and the clues they reveal for the origin an,d evolution of the solar system. This collective knowledge, prepared by a team of more than one hundred international authorities on asteroids, includes new insights into asteroid-meteorite connections, possible relationships with comets, and the hazards posed by asteroids colliding with Earth. The book's contents include reports on surveys based on remote observation and summaries of physical properties; results of in situ exploration; studies of dynamical, collisional, cosmochemical, and weathering evolutionary processes; and discussions of asteroid families and the relationships between asteroids and other solar system bodies. Two previous Space Science Series volumes have established standards for research into asteroids. Asteroids III carries that tradition forward in a book that will stand as the definitive source on its subject for the next decade.

Book Synopsis Defending Planet Earth by : National Research Council
Download or read book Defending Planet Earth written by National Research Council and published by National Academies Press. This book was released on 2010-07-21 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth. The majority of this funding supports the operation of several observatories that scan the sky searching for NEOs. This, however, is insufficient in detecting the majority of NEOs that may present a tangible threat to humanity. A significantly smaller amount of funding supports ways to protect the Earth from such a potential collision or "mitigation." In 2005, a Congressional mandate called for NASA to detect 90 percent of NEOs with diameters of 140 meters of greater by 2020. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies identifies the need for detection of objects as small as 30 to 50 meters as these can be highly destructive. The book explores four main types of mitigation including civil defense, "slow push" or "pull" methods, kinetic impactors and nuclear explosions. It also asserts that responding effectively to hazards posed by NEOs requires national and international cooperation. Defending Planet Earth: Near-Earth Object Surveys and Hazard Mitigation Strategies is a useful guide for scientists, astronomers, policy makers and engineers.
Book Synopsis Space Policy in the Twenty-First Century by : W. Henry Lambright
Download or read book Space Policy in the Twenty-First Century written by W. Henry Lambright and published by JHU Press. This book was released on 2003 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though more than forty years old, the space age has just begun, and questions about its future abound. What will replace the Space Shuttle? Will the International Space Station justify its $100 billion potential cost? Are asteroids real threats to Earth or just the subject of science fiction movies? Will humans land on Mars? Will the search for extraterrestrial life be rewarded? In Space Policy in the Twenty-First Century, W. Henry Lambright brings together ten top-ranking observers of United States space exploration to address these and other issues relating to the future of the space program. While the U.S. no longer competes with the Soviets for technological "firsts," they argue, ideology and national image remain at the core of space policy, with other factors playing subordinate roles. Reminding readers of the historical highlights, the authors pose searching questions about the priorities and applications of space science, manned vs. unmanned flights, and commercial access to the space enterprise. Contributors include: Christopher F. Chyba, SETI Institute and Stanford University; Ronald J. Deibert, University of Toronto; Daniel H. Deudney, the Johns Hopkins University; W. Henry Lambright, Syracuse University; Roger D. Launius, NASA; Karl A. Leib, Syracuse University; John M. Logsdon, George Washington University; Howard E. McCurdy, American University; Scott N. Pace, White House Office of Science and Technology Policy; and Debora L. VanNijnatten, Wilfrid Laurier University.
