Available in PDF, EPUB and Kindle. Book excerpt: The threat of asteroid impacts on Earth poses a low-probability but high consequence risk, with possible outcomes ranging from regional to global catastrophe. However, unique amongst such global threats we have the capability of averting such disasters. Diversion approaches by either kinetic impactor or nuclear energy deposition are the two most practical technologies for mitigating hazardous near Earth asteroids. One of the greatest challenges in understanding our options is the uncertain response of asteroids to such impulsive techniques, due both to our lack of knowledge of the composition and structure of these objects as well as their highly varied nature. Predicting whether we will simply divert or break up a given object is a crucial: the weak self-gravity and inferred weak structure of typical asteroids present the strong possibility the body will fragment for modest impulses. Predictive modeling of failure and fragmentation is one important tool for such studies. In this paper we apply advances in modeling failure and fracture using Adaptive Smoothed Particle Hydrodynamics (ASPH) to understand mega-cratering on asteroids as a validation exercise, and show examples of diverting the near Earth asteroid Bennu using both a kinetic impactor and ablative blow-off due to nuclear energy deposition.
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 Space Systems and Sustainability written by Joseph N. Pelton and published by Springer Nature. This book was released on 2021-08-13 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his latest book, space scientist, futurist, and educator Joseph N. Pelton explores a dozen ways that Planet Earth is at “existential” risk, along with the many ways that space systems, data analytics, and advanced networking systems can help us cope with these global challenges. The chapters examine in a straightforward way how satellite systems and technol- ogy can drastically transform fields such as pandemic tracking and global medical responses, cosmic hazard monitoring, nuclear energy and waste disposal, water and land pollution, tele-education/telemedicine, and military conflict. Such examples show how orbiting smart systems will play an ever more vital role in our vulnerable modern world, allowing us to monitor, track, and respond to mounting problems of the 21st century. Dr. Pelton takes a broad view, probing the social, economic, and regulatory factors that are crucial to creating a more sustainable “Spaceship Earth.” This book is a call to action, promoting more organized international collaboration and investment in space technologies that can enable global change.

Download or read book New Solutions for the Space Debris Problem written by Joseph N. Pelton and published by Springer. This book was released on 2015-05-06 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing a pressing issue in space policy, Pelton explores the new forms of technology that are being developed to actively remove the defunct space objects from orbit and analyzes their implications in the existing regime of international space law and public international law. This authoritative review covers the due diligence guidelines that nations are using to minimize the generation of new debris, mandates to de-orbit satellites at end of life, and innovative endeavours to remove non-functional satellites, upper stage rockets and other large debris from orbit under new institutional, financial and regulatory guidelines. Commercial space services currently exceed 100 billion USD business per annum, but the alarming proliferation in the population of orbital debris in low, medium and geosynchronous satellite orbits poses a serious threat to all kinds of space assets and applications. There is a graver concern that the existing space debris will begin to collide in a cascading manner, generating further debris, which is known as the Kessler Syndrome. Scientific analysis has indicated an urgent need to perform space debris remediation through active removal of debris and on-orbit satellite servicing.
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.
