Book excerpt: Impacts by Earth-approaching asteroids and comets pose a significant hazard to life and property. Although the annual probability of the Earth being struck by a large asteroid or comet is extremely small, the consequences of such a collision are so catastrophic that it is prudent to assess the nature of the threat and to prepare to deal with it. The first step in any program for the prevention or mitigation of impact catastrophes must involve a comprehensive search for Earth-crossing asteroids and comets and a detailed analysis of their orbits. At the request of the U.S. Congress, NASA has carried out a preliminary study to define a program for dramatically increasing the detection rate of Earth-crossing objects, as documented in this workshop report.

Download or read book Near Earth Object Surveys and Hazard Mitigation Strategies written by National Research Council and published by National Academies Press. This book was released on 2010-01-30 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States is currently the only country with an active, government-sponsored effort to detect and track potentially hazardous near-Earth objects (NEOs). Congress has mandated that NASA detect and track 90 percent of NEOs that are 1 kilometer in diameter or larger. These objects represent a great potential hazard to life on Earth and could cause global destruction. NASA is close to accomplishing this goal. Congress has more recently mandated that by 2020 NASA should detect and track 90 percent of NEOs that are 140 meters in diameter or larger, a category of objects that is generally recognized to represent a very significant threat to life on Earth if they strike in or near urban areas. Achieving this goal may require the building of one or more additional observatories, possibly including a space-based observatory. Congress directed NASA to ask the National Research Council to review NASA's near-Earth object programs. This interim report addresses some of the issues associated with the survey and detection of NEOs. The final report will contain findings and recommendations for survey and detection, characterization, and mitigation of near-Earth objects based on an integrated assessment of the problem.

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.

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.

This book was released on 2013-03-14 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book's purpose is to provide the quantitative foundation for beginning to think about developing energy and minerals outside of Earth's atmosphere that are necessary to support scientific missions, space and extra-terrestrial scientific stations and permanent colonies, and ultimately expand Earth's economy beyond the near-earth environment to include space resources. We cannot envision a situation where all resources required for future space activities are exported from Earth, therefore, this book clearly illustrates that an effective economy is possible beyond Earth's surface when we consider the resources available in near-Earth space. Our first audience is members of AAPG, American Institute of Mining, Metallurgical and Petroleum Engineers (AIME) and other professionals engaged in energy and resource development. As energy professionals, we are concerned on a daily basis with providing the necessary energy and minerals required for our growing world population and the increasing standard of living that comes with ample energy availability. And more than anything else, AAPG members are explorers. We are the professionals who have pushed back the boundaries of our resource base, from capturing petroleum resources from surface seeps, to drilling onshore wells to extract oil and gas, and to venturing offshore into increasingly difficult and hostile environments to supply the cheap and abundant energy made available by our advances in technology. There are more similarities than differences between deepwater exploration and development, and space exploration. Beyond our own members, however, our audience is every rational human being who understands human health and well-being, quality of life, education and freedom are dependent on the energy and minerals that support our advanced civilization. Space is the next frontier, and as the world civilization expands beyond Earth's surface we hope this publication serves to illustrate there are abundant opportunities to support and maintain - and in fact, allow to prosper - civilization's expansion into space -- Publisher's website.

Download or read book The Asteroid Threat written by William E. Burrows and published by . This book was released on 2014 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents a realistic, workable plan for defusing a potentially lethal threat from a rogue asteroid or comet. The explosion of a large meteor over Chelyabinsk, Siberia, in February 2013 is just the latest reminder that planet Earth is vulnerable to damaging and potentially catastrophic collisions with space debris of various kinds. In this informative and forward-looking book, veteran aerospace writer William E. Burrows explains what we can do in the future to avoid far more serious impacts from "Near-Earth Objects" (NEOs), as they are called in the planetary defense community. The good news is that humanity is now equipped with the advanced technology necessary to devise a long-term strategy to protect the planet. Burrows outlines the following key features of an effective planetary defense strategy- * A powerful space surveillance system capable of spotting a serious threat from space at least a year in advance * A space craft "nudge" that would throw a collision-course asteroid off target long before it poses the threat of imminent impact * A weapons system to be used as a last-ditch method to blast an NEO should all else fail. The author notes the many benefits for world stability and increasing international cooperation resulting from a united worldwide effort to protect the planet. Combining realism with an optimistic can-do attitude, Burrows shows that humanity is capable of overcoming a potentially calamitous situation.
