The threat to Earth due to the impact of an Earth-crossing asteroid or comet is not new, but scientists have only recently recognized it as a continuing threat. The past ten years reveal several frightening near misses, and “hits” by bodies too small to survive long enough in the atmosphere to cause damage. The hazard created when an object strikes Earth varies greatly, from a minimum of no damage due to the object's destruction in the atmosphere to a maximum of millions of deaths, extinction of species, and an end to present civilization. While the potential hazard is great, the probability of occurrence is low, but an impact will happen; the only question is when. Technology exists to dealwith this threat, but serious, organized effort to identify potential threatening objects and to deflect threatening objects is virtually nonexistent. This book analyzes planetary defense issues and develops seven recommendations for national policy and near term actions to be taken by the United States to develop and implement a system to defend Earth from potential impact by comets and asteroids.

Planetary defense from near-Earth objects such as asteroids is a far more nuanced and challenging topic than it might seem. Each day, technology is making it easier to detect asteroid impact threats in advance, but at present, there is still no easy way to design and implement any form of global defense. This book examines how various asteroid deflection methods can change global political affairs. The authors believe that the final policy for potential Earth impacts should be based on practical engineering solutions and innovative architectural structures, while at the same time reflecting the most recent political science contributions in ethical security studies and security cosmopolitanism. Their focus is not limited to effective engineering solutions, but rather extends to how such proposals resonate in possible political structures of the future. Planetary defense cannot be achieved with technology alone; the chapters in this volume highlight the issues that arise when space science and technology intersect with political science. This complex interdisciplinary project not only demands global participation and collaboration, but also proposes the way we can achieve it. The authors explore various concepts of governance and their far-reaching implications for planetary defense and vice versa—how scientific progress in Solar System observations and asteroid collision engineering influence political science and put pressure on the international legal framework. The text is intentionally written for a diverse scholarly and diplomatic audience in a style accessible to non-specialists and practitioners and can be read by those across diverse disciplinary backgrounds.

This timely resource provides a history of the development of space weapons and warfare strategies and a comprehensive reference guide to the growing literature on the subject. Space Warfare and Defense: A Historical Encyclopedia and Research Guide provides comprehensive coverage of the development of space as a possible arena for warfare, exploring the military uses of space—past, present, and future—and specific details of actual space weapons systems. The encyclopedia spans the breadth of U.S. military space policy; comparable programs in the Soviet Union, China, and the European Union; and the full array of international agreements designed to regulate the military uses of space. In addition, the encyclopedia includes an extensive reference guide (nearly 40 percent of the book) directing readers to the essential literature on space weapons and defense systems produced by the United States, other governments, research institutions, and additional sources. At a time when space is becoming an increasingly important place of military competition and potential conflict, Space Warfare and Defense dispels the myths and examines the realities of what may become humanity's ultimate battlefield.

Near Earth objects (NEOs) have the potential to cause significant damage on Earth. In December 2018, an asteroid exploded in the upper atmosphere over the Bering Sea (western Pacific Ocean) with the explosive force of nearly 10 times that of the Hiroshima bomb. While the frequency of NEO impacts rises in inverse proportion to their sizes, it is still critical to monitor NEO activity in order to prepare defenses for these rare but dangerous threats. Currently, NASA funds a network of ground-based telescopes and a single, soon-to-expire space-based asset to detect and track large asteroids that could cause major damage if they struck Earth. This asset is crucial to NEO tracking as thermal-infrared detection and tracking of asteroids can only be accomplished on a space-based platform. Finding Hazardous Asteroids Using Infrared and Visible Wavelength Telescopes explores the advantages and disadvantages of infrared (IR) technology and visible wavelength observations of NEOs. This report reviews the techniques that could be used to obtain NEO sizes from an infrared spectrum and delineate the associated errors in determining the size. It also evaluates the strengths and weaknesses of these techniques and recommends the most valid techniques that give reproducible results with quantifiable errors.

"To commemorate the 50th anniversary of the first successful planetary mission, Mariner 2 sent to Venus in 1962, the NASA History Program Office, the Division of Space History at the National Air and Space Museum, NASA's Science Mission Directorate, and the Jet Propulsion Laboratory organized a symposium. "Solar System Exploration @ 50" was held in Washington, D.C., on 25-26 October 2012. The purpose of this symposium was to consider, over the more than 50-year history of the Space Age, what we have learned about the other bodies of the solar system and the processes by which we have learned it. Symposium organizers asked authors to address broad topics relating to the history of solar system exploration such as various flight projects, the development of space science disciplines, the relationship between robotic exploration and human spaceflight, the development of instruments and methodologies for scientific exploration, as well as the development of theories about planetary science, solar system origins and implications for other worlds. The papers in this volume provide a richly textured picture of important developments - and some colorful characters - in a half century of solar system exploration. A comprehensive history of the first 50 years of solar system exploration would fill many volumes. What readers will find in this volume is a collection of interesting stories about money, politics, human resources, commitment, competition and cooperation, and the "faster, better, cheaper" era of solar system exploration"--

This contributed volume addresses the future development of space law in light of our ever-growing space activities, the multiplicity of new space actors and the challenges posed by novel space technologies. Unlike existing space law literature, it sets its sights on the future, envisaging how space law could and should evolve in coming decades. Written by experienced professors, academics and practitioners in the field, this edited volume constitutes a valuable tool for understanding the current state of space law, the challenges it is called upon to address and the new phase it is about to enter. In addition, this book initiates a discussion de lege ferenda, addressing the letter and spirit of space law in the world of modern and future space activities. These papers were presented at “The Space Treaties at Crossroads: Considerations de lege ferenda,” held on August 28 to 29, 2015, in Athens, Greece. The conference was jointly organized by the National and Kapodistrian University of Athens and the Institute of Air and Space Law of McGill University

Impacts by asteroids or comets on Earth may lead to natural disasters of catastrophic dimensions. This book addresses legal and policy aspects of ‘planetary defence’ activities by space agencies and other actors aiming at the prediction and mitigation of Near-Earth Objects (NEOs).
