An excerpt: "In a world of warmth and light and living things we soon forget that we are surrounded by a vast universe that is cold and dark and deadly dangerous, just beyond our door. On a starry night, when we look out into the darkness that lies around us, the view can be misleading in yet another way: for the brightness and sheer number of stars, and their chance groupings into familiar constellations, make them seem much nearer to each other, and to us, that in truth they are. And every one of them--each twinkling, like a diamond in the sky--is a white-hot sun, much like our own. The nearest stars in our own galaxy--the Milky Way-- are more than a million times further away from us than our star, the Sun."

Book excerpt: This in-depth study of U.S. involvement in the modern Middle East carefully weighs the interplay of domestic, cultural, religious, diplomatic, international, and military events in one of the world's most troubled regions. The monumental, five-volume The Encyclopedia of Middle East Wars: The United States in the Persian Gulf, Afghanistan, and Iraq Conflicts is a must-have resource for anyone seeking to comprehend U.S. actions in this volatile region. Under the expert editorship of Spencer C. Tucker, the encyclopedia traces 20th- and 21st-century U.S. involvement in the Middle East and south-central Asia, concentrating on the last three decades. Beginning with the 1980–1988 Iran-Iraq War, it covers the 1979–1989 Soviet occupation of Afghanistan, the 1991 Persian Gulf War, allied punitive actions against Iraq during the 1990s, the Afghanistan War, the Iraq War, and the Global War on Terror. Many smaller military actions against Iran, Iraq, Libya, Afghanistan, and other regimes that have been involved in international terrorism are also included. Diplomacy, religion as it pertains to Middle East conflict, and social/cultural developments are other key subjects of analysis, as is the interplay of politics with military policy in the United States and other nations involved in the region.

Available in PDF, EPUB and Kindle. Book excerpt: Magnetic storms may cause damage to satellites, radiation hazard to astronauts, disruption of radio communications, and interruption of ground electric power lines. Space weather prediction becomes an important issue to be addressed in the twenty-first century. International Solar Terrestrial Program (ISTP) employs five satellites to probe the solar wind and magnetosphere, providing valuable information for space weather prediction. The Asia-Pacific region is becoming one of the economic centers in the world. The continuous drive for scientific and technological progress in parallel is evidenced by the establishment of many space research organizations in many countries of this area. In Taiwan, the National Space Program Office (NSPO) established her third satellite program -- COSMIC (Constellation Obsering Systems for Meteorology, Ionosphere and Climate), which is a science experiment to demonstrate the utility of atmospheric radio limb soundings from a constellation of six low-earth orbiting satellites in operational weather prediction, space weather monitoring, and climate monitoring and research. In order to provide a forum to discuss the many new results in this rapid-moving field and to forge international collaborations, a three-day COSPAR Colloquium on "Space Weather Study Using Multipoint Techniques" was held. This colloquium have provided a forum for experts from the international community to present new results on the timely topic "space weather".

Book excerpt: Space weather refers to variations in the space environment between the sun and Earth (and throughout the solar system) that can affect technologies in space and on Earth. Space weather can disrupt the technology that forms the backbone of this country's economic vitality and national security, including satellite and airline operations, communications networks, navigation systems, and the electric power grid. As the Nation becomes ever more dependent on these technologies, space weather poses an increasing risk to infrastructure and the economy. Further, the Strategic National Risk Assessment has identified space weather as a hazard that poses significant risk to the security of the Nation. Clearly, reducing vulnerability to space weather needs to be a national priority. The National Space Weather Strategy (Strategy) and the accompanying National Space Weather Action Plan (Action Plan) together seek to enhance the integration of existing national efforts and to add important capabilities to help meet growing demands for space-weather information. The Strategy and Action Plan build on recent efforts to reduce risks associated with natural hazards and improve resilience of essential facilities and systems, aiming to foster a collaborative environment in which government, industry, and the American people can better understand and prepare for the effects of space weather. The Nation must continue to leverage existing public and private networks of expertise and capabilities and pursue targeted enhancements to improve the ability to manage risks associated with space weather. This book outlines objectives for enhancing the Nation's space-weather readiness in three key areas: national preparedness, forecasting, and understanding. It also describes the study process, the study requirements and their relevance and importance, an assessment and accounting of current and planned space weather observing systems used or to be used for operations, an analysis of gaps between the observing systems' capabilities and their ability to meet documented requirements, and a summary of key findings.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an overview of space strategy in the 21st century. The purpose of space strategy is to coordinate, integrate, and prioritize space activities across security, commercial, and civil sectors. Without strategy, space activities continue to provide value, but it becomes difficult to identify and execute long-term programs and projects and to optimize the use of space for security, economic, civil, and environmental ends. Strategy is essential for all these ends since dependence on, and use of, space is accelerating globally and space is integrated in the fabric of activities across all sectors and uses. This volume identifies a number of areas of concern pertinent to the development of national space strategy, including: intellectual foundations; political challenges; international cooperation and space governance; space assurance and political, organizational, and management aspects specific to security space strategy. The contributing authors expand their focus beyond that of the United States, and explore and analyse the international developments and implications of national space strategies of Russia, China, Europe, Japan, India, Israel, and Brazil. This book will be of much interest to students of space power and politics, strategic studies, foreign policy and International Relations in general.

Available in PDF, EPUB and Kindle. Book excerpt: Looking for a way to reduce your environmental impact? Find your route to a more sustainable lifestyle with Dick Strawbridge and his son James. We can all take steps to reduce our carbon footprint and be more self-sufficient. For some, that might mean heading to the countryside to live off the land. For the rest of us, the reality might involve smaller, but no less important, lifestyle changes: cutting back on plastic or food waste, growing vegetables, preserving meat and fish, preparing jams and chutneys, baking sourdough bread, making your own plant-based milks, or keeping a chicken or two. Dick and James Strawbridge know what it's like to make these changes. Between them, they've lived on a smallholding, in a terraced house, and even a chateau. In this updated book, they share everything they've learned and give you the tools you need for a more rewarding and environmentally-conscious life. Whether you want to completely revamp your lifestyle or just make everyday changes that will make an impact, Self-Sufficiency for the 21st Century is the perfect place to start.

This book was released on 2009-06-08 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adverse effects of extreme space weather on modern technology-power grid outages, high-frequency communication blackouts, spacecraft anomalies-are well known and well documented, and the physical processes underlying space weather are also generally well understood. Less well documented and understood, however, are the potential economic and societal impacts of the disruption of critical technological systems by severe space weather. This volume, an extended four-color summary of the book, Severe Space Weather Events-Understanding Societal and Economic Impacts, addresses the questions of space weather risk assessment and management. The workshop on which the books are based brought together representatives of industry, the government, and academia to consider both direct and collateral effects of severe space weather events, the current state of the space weather services infrastructure in the United States, the needs of users of space weather data and services, and the ramifications of future technological developments for contemporary society's vulnerability to space weather. The workshop concluded with a discussion of un- or underexplored topics that would yield the greatest benefits in space weather risk management.

Available in PDF, EPUB and Kindle. Book excerpt: From the interior of the Sun, to the upper atmosphere and near-space environment of Earth, and outward to a region far beyond Pluto where the Sun's influence wanes, advances during the past decade in space physics and solar physics-the disciplines NASA refers to as heliophysics-have yielded spectacular insights into the phenomena that affect our home in space. Solar and Space Physics, from the National Research Council's (NRC's) Committee for a Decadal Strategy in Solar and Space Physics, is the second NRC decadal survey in heliophysics. Building on the research accomplishments realized during the past decade, the report presents a program of basic and applied research for the period 2013-2022 that will improve scientific understanding of the mechanisms that drive the Sun's activity and the fundamental physical processes underlying near-Earth plasma dynamics, determine the physical interactions of Earth's atmospheric layers in the context of the connected Sun-Earth system, and enhance greatly the capability to provide realistic and specific forecasts of Earth's space environment that will better serve the needs of society. Although the recommended program is directed primarily at NASA and the National Science Foundation for action, the report also recommends actions by other federal agencies, especially the parts of the National Oceanic and Atmospheric Administration charged with the day-to-day (operational) forecast of space weather. In addition to the recommendations included in this summary, related recommendations are presented in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Technology has propelled the atmospheric sciences from a fledgling discipline to a global enterprise. Findings in this field shape a broad spectrum of decisionsâ€"what to wear outdoors, whether aircraft should fly, how to deal with the issue of climate change, and more. This book presents a comprehensive assessment of the atmospheric sciences and offers a vision for the future and a range of recommendations for federal authorities, the scientific community, and education administrators. How does atmospheric science contribute to national well-being? In the context of this question, the panel identifies imperatives in scientific observation, recommends directions for modeling and forecasting research, and examines management issues, including the growing problem of weather data availability. Five subdisciplinesâ€"physics, chemistry, dynamics and weather forecasting, upper atmosphere and near-earth space physics, climate and climate changeâ€"and their status as the science enters the twenty-first century are examined in detail, including recommendations for research. This readable book will be of interest to public-sector policy framers and private-sector decisionmakers as well as researchers, educators, and students in the atmospheric sciences.
