This book was released on 2018-07-17 with total page 76 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: THE MEETING The IAU Symposium 160 ASTEROIDS COMETS METEORS 1999 has been held at Villa Carlotta in Belgirate, on the shore of Lago Maggiore (Italy), from June 14 to June 18, 1993. It has been organized by the Astronomical Observatory of Torino and by the Lunar and Planetary Institute of Houston. It has been a very large meeting, with 323 registered participants from 38 countries. The scientific program included 29 invited reviews, 106 oral communications, and 215 posters. The subjects covered included all the aspects of the studies of the minor bodies of the solar system, including asteroids, comets, meteors, meteorites, interplanetary dust, with special focus on the interrelationships between these. The meeting was structured as follows. 5 morning plenary sessions have been devoted to invited reviews on: (1) search programs (2) populations of small bodies (3) dynamics (4) physical observations and modelling (5) origin and evolution. Two afternoon plenary sessions have been devoted to space missions to small bodies and to interrelationships between the different populations. The afternoon parallel sessions have been devoted to: dynamics of comets; Toutatis, Ida, Gaspra; physical processes in cometary comae and tails; meteorites; the cosmogonic message from cometary nuclei; physics of asteroids; the interplanetary dust complex; comet nuclei; meteors; composition and material properties of comets; dynamics of asteroids.

Available in PDF, EPUB and Kindle. Book excerpt: Using Space to Save Earth Veteran science journalist William E Burrows offers a bold new mission for the U.S. space program: to protect the Earth from the ever-growing number of perils that threaten our way of life – and even our very survival. We are living through one of the most dangerous times in human history. Nuclear, chemical, and biological weapons technology are proliferating, and missile technology is falling into more and more hands. Extreme natural disasters like hurricanes, floods, fires, and earthquakes, are becoming increasingly costly – not only in dollars, but in lives – as population expands. Environmental crises threaten to provoke massive famines and widespread social collapse. Asteroids the size of battleships streak within striking distance of the earth every year. One strategy offers the best hope of protecting us from all of these dangers – a revitalized national space program that coordinates efforts in global defense, in environmental protection, in communications, and in military security. The Survival Imperative offers an impassioned argument for this bold initiative. To demonstrate the urgency of his cause, Burrows presents a vivid scenario: an impact by a moderately large asteroid that triggers a series of nuclear exchanges, environmental devastation, and the slow disintegration of civilization. And he examines the existing space program from the heady days of the Moon landing through the political compromises that have characterized the history of NASA in the 35 years following our retreat from the Moon. Most of all, Burrows warns that the primary obstacle to achieving a true planetary defense program is not financial or scientific, but social–an unwillingness to acknowledge the urgency of the crisis, and to take the political risks needed to address it. The question, says Burrows, is not whether we can do it, but whether we will act before it's too late.

Download or read book Mathematics of Planet Earth written by Eulogio Pardo-Igúzquiza and published by Springer Science & Business Media. This book was released on 2013-10-07 with total page 847 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely recognized that the degree of development of a science is given by the transition from a mainly descriptive stage to a more quantitative stage. In this transition, qualitative interpretations (conceptual models) are complemented with quantification (numerical models, both, deterministic and stochastic). This has been the main task of mathematical geoscientists during the last forty years - to establish new frontiers and new challenges in the study and understanding of the natural world. Mathematics of Planet Earth comprises the proceedings of the International Association for Mathematical Geosciences Conference (IAMG2013), held in Madrid from September 2-6, 2013. The Conference addresses researchers, professionals and students. The proceedings contain more than 150 original contributions and give a multidisciplinary vision of mathematical geosciences.

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 Mitigation of Hazardous Comets and Asteroids written by M. J. S. Belton and published by Cambridge University Press. 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 Commercial Space Exploration written by Jai Galliott and published by Routledge. This book was released on 2016-03-09 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not since man set foot on the moon over four decades ago has there been such passion and excitement about space exploration. This enthusiasm and eagerness has been spurred on by the fact that for the first time since the very beginning of the space age, space travel is no longer limited to an elite group of highly trained and well-disciplined military officers and test pilots. Instead, we must understand that the possibility of commercial space travel is already on our horizon and that it comes with a number of significant practical and moral challenges. Our level of scientific development and ability to influence international affairs and policy confers upon us an obligation to study the ethical, legal and social considerations associated with space exploration and understanding the potential consequences from the beginning is critical. This volume provides the first comprehensive and unifying analysis concerning the rise of private space exploration, with a view toward developing policy that may influence real-world decision making. The plethora of questions demanding serious attention - privatisation and commercialisation, the impact on the environment, health futures, risk assessment, responsibility and governance - are directly addressed in this scholarly work.

Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of Space Security focuses on the interaction between space technology and international and national security processes. Saadia M. Pekkanen and P.J. Blount have gathered a group of key scholars who bring a range of analytical and theoretical perspectives to take an analytically-eclectic approach to assessing space security from an international relations (IR) theory perspective. Bringing together scholarship from a group of leading experts, this volume explains how these contemporary changes will affect future security in, from, and through space.
Download or read book Asteroids written by Curtis Peebles and published by Smithsonian Institution. This book was released on 2016-04-26 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asteroids suggest images of a catastrophic impact with Earth, triggering infernos, tidal waves, famine, and death -- but these scenarios have obscured the larger story of how asteroids have been discovered and studied. During the past two centuries, the quest for knowledge about asteroids has involved eminent scientists and amateur astronomers, patient research and sudden intuition, advanced technology and the simplest of telescopes, newspaper headlines and Cold War secrets. Today, researchers have named and identified the mineral composition of these objects. They range in size from 33 feet to 580 miles wide and most are found in a belt between the orbits of Mars and Jupiter. Covering all aspects of asteroid investigation, Curtis Peebles shows how ideas about the orbiting boulders have evolved. He describes how such phenomena as the Moon's craters and dinosaur extinction were gradually, and by some scientists grudgingly, accepted as the results of asteroid impacts. He tells how a band of icy asteroids rimming the solar system, first proposed as a theory in the 1940s, was ignored for more than forty years until renewed interest and technological breakthroughs confirmed the existence of the Kuiper Belt. Peebles also chronicles the discovery of Shoemaker-Levy 9, a comet with twenty-two nuclei that crashed into Jupiter in 1994, releasing many times the energy of the world's nuclear arsenal. Showing how asteroid research is increasingly collaborative, the book provides insights into the evolution of scientific ideas and the ebb and flow of scientific debate.
