Frontiers Of Space Risk

CHOICE Recommended Title, March 2019 This book brings together diverse new perspectives on current and emerging themes in space risk, covering both the threats to Earth-based activities arising from space events (natural and man-made), and those inherent in space activity itself. Drawing on the latest research, the opening chapters explore the dangers from asteroids and comets; the impact of space weather on critical technological infrastructure on the ground and in space; and the more uncertain threats posed by rare hazards further afield in the Milky Way. Contributors from a wide range of disciplines explore the nature of these risks and the appropriate engineering, financial, legal, and policy solutions to mitigate them. The coverage also includes an overview of the space insurance market; engineering and policy perspectives on space debris and the sustainability of the space environment. The discussion then examines the emerging threats from terrorist activity in space, a recognition that space is a domain of war, and the challenges to international cooperation in space governance from the nascent asteroid mining industry. Features: Discusses developments and risks relevant to the public and private sectors as access to the space environment expands Offers an interdisciplinary approach blending science, technology, and policy Presents a high-level international focus, with contributions from academics, policy makers, and commercial space consultants

This book shares a range of new and diverse insights on On-Orbit Servicing (OOS), and examines its implications especially from political, legal, economic, and security perspectives. OSS has been evolving rapidly and presents both challenges and opportunities, such as in-space repairs, refuelling, refurbishment of spacecraft and servicing satellites, which could play a critical role in extending satellite lifecycles, while also representing a valuable next step in debris mitigation. At the same time, many legal questions have arisen in connection with OOS: the need to prevent hostile actions under the pretext of OSS; the distinction between governmental and non-governmental OOS operators; the status of re-worked and recycled space objects; the issue of control in terms of operations performed in orbit, i.e., in the international sphere; the status of objects manufactured in orbit and applicable law, including liability and registration; and the impacts on insurance law and risk management. Finally, the book examines the implications of OOS for emerging space actors in the Global South, and recommends a paradigm shift to help developing countries fully recognise the necessity and urgency of being involved in discussions on OSS, as opposed to leaving it up to the developed space actors. This book will be of great interest to practitioners, academics, and students working in the space sector and related fields.

NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to cancer induction. Other possible effects include central nervous system damage, cataracts, cardiovascular damage, heritable effects, impaired wound healing, and infertility. Recent research, much of which has been sponsored by NASA, has focused on understanding and quantifying the radiation health risks posed by space radiation environments. Although many aspects of the space radiation environments are now relatively well characterized, important uncertainties still exist regarding biological effects and thus regarding the level and types of risks faced by astronauts. This report presents an evaluation of NASA's proposed space radiation cancer risk assessment model, which is described in the 2011 NASA report, Space Radiation Cancer Risk Projections and Uncertainties-2010. The evaluation in Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation considers the model components, input data (for the radiation types, estimated doses, and epidemiology), and the associated uncertainties. This report also identifies gaps in NASA's current research strategy for reducing the uncertainties in cancer induction risks.

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.

Ever since the completion of the Apollo program, there has been a lack of consensus about the future of human spaceflight. The Columbia tragedy in February 2003 rekindled public debate about this question. In November 2003, the Space Studies Board and the Aeronautics and Space Engineering Board organized a workshop to explore aspects of the question, what should be the principal purpose, goals, and priorities of the U.S. civil space program? This report presents a factual summary of that workshop, which identified past lessons learned and guiding principles for the future of the civil space program. Seven broad themes emerged from the workshop, and these themes are highlighted in the report. The report also presents discussions of strategies for the human spaceflight program and guiding principles of and boundary conditions for a 21st century space policy.

This book compares the cultural politics of the U.S. space and Antarctic programs during the Cold War. It analyzes how culturally salient terms, especially the nationalist motif of the frontier, were used to garner public support for these strategic initiatives and, more generally, United States internationalism during this period.

The aim of this book is to bring students of economics and finance who have only an introductory background in mathematics up to a quite advanced level in the subject, thus preparing them for the core mathematical demands of econometrics, economic theory, quantitative finance and mathematical economics, which they are likely to encounter in their final-year courses and beyond. The level of the book will also be useful for those embarking on the first year of their graduate studies in Business, Economics or Finance. The book also serves as an introduction to quantitative economics and finance for mathematics students at undergraduate level and above. In recent years, mathematics graduates have been increasingly expected to have skills in practical subjects such as economics and finance, just as economics graduates have been expected to have an increasingly strong grounding in mathematics. The authors avoid the pitfalls of many texts that become too theoretical. The use of mathematical methods in the real world is never lost sight of and quantitative analysis is brought to bear on a variety of topics including foreign exchange rates and other macro level issues.
