Book Description
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 Description
Acerbic dark humour meets hardcore science in this mind-boggling exploration of the nine worst ways the world could end Discover the mind-boggling science of the coming apocalypse! 'Curiously pleasurable… this will help you get your everyday problems into perspective.' Independent Which will get us first? The supervolcano in Yellowstone National Park? An asteroid hurtling through outer space? Black holes from CERN gobbling up the solar system? An army of deranged, super-intelligent AI? Or – who knows – alien invasion? Armed with lavish illustrations and their one-of-a-kind 'Catastrophometer', Dr David Darling and Dr Dirk Schulze-Makuch introduce the disasters you never saw coming, unpicking the science that makes them genuine possibilities, and providing everything from survival tips to danger ratings. So sit back, face the inevitable, and discover the delights of the nine oddest ways the world could end.

Book Description
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 Description
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.

Book Description
Leading specialists in various disciplines were first invited to a multidisciplinary workshop funded by ICSU on the topic to gain a better appreciation and perspective on the subject of comet/asteroid impacts as viewed by different disciplines. This volume provides a necessary link between various disciplines and comet/asteroid impacts.

Book Description
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.
