When the first sputnik was launched and the space era began, few gave thought to the possible negative impact of putting satellites into orbit. In fact, man's space activity has led to the formation of a new media named "space debris," i.e. man-made objects and their fragments launched into space, currently inactive and no longer serving any useful purpose. Space Debris: Hazard Evaluation and Mitigation will appeal to readers unfamiliar with the issues, as well as experts and designers. It introduces concepts behind the problems of space ecology. The volume features actual data on the space debris environment; new mathematical models for space debris evolution, production and self-production; description of the existing software and concepts for shield design. The author also reviews methods of collision risk assessment, including the attitudes and inclinations of orbits, collision hazard evaluation and suggestions for preventative measures.

This book examines the rise of great power competition in space, including the relevant and practical space strategies for China, Russia, the United States, and other countries. The work discusses the concepts and writings of past strategists, such as Thucydides, Sun Tzu, and Clausewitz, in relation to warfare initiated in or extending into space. This analysis underscores why polities initiate war based upon an assessment of fear, honor, and interest, and explains why this will also be true of war in space. Based upon the timeless strategic writings of the past, the book uncovers the strategy of space warfare, along with the concepts of deterrence, dissuasion, and the inherent right of self-defense, and outlines strategies for great, medium, and emerging space powers. Additionally, it highlights changes needed to space strategy based upon the Law of Armed Conflict, norms of behavior, and Rules of Engagement. The work also examines advancements and emerging trends in the commercial space sector, as well as what these changes mean for the implementation of a practical space strategy. Given the rise of great power competition in space, this work presents a space strategy based upon historical experience. This book will be of much interest to students of space policy, strategic studies, and International Relations.

This volume identifies and evaluates the relationship between outer-space geography and geographic position (astrogeography), and the evolution of current and future military space strategy. In doing so, it explores five primary propositions. First, many classical geopolitical theories of military development are fully compatible with the realm of outer space. Second, how geographical position relates to new technology. Such evolution has developed through sea, rail and air power. Space power is the logical and apparent heir. Third, the special terrain of solar space dictates specific tactics and strategies for efficient exploitation of space resources. Fourth, the concept of space as a power base in classical, geopolitical thought will easily conform to the use of outer space as an ultimate national power base. Finally, a thorough understanding of the astromechanical and physical demarcations of outer space can prove useful to planners, and will prove critical to military strategists in the future. An optimum deployment of space assets will be essential on the current terrestrial and future-based battlefield.

If you had a trillion dollars and a year to spend it for the good of the world and the advancement of science, what would you do? It's an unimaginably large sum, yet it's only around one per cent of world GDP, and about the valuation of Google, Microsoft or Amazon. It's a much smaller sum than the world found to bail out its banks in 2008 or deal with Covid-19. But what could you achieve with $1 trillion? You could solve the problem of the pandemic, for one, and eradicate malaria, and maybe cure all disease. You could end global poverty. You could settle on the Moon and explore the solar system. You could build a massive particle collider to probe the nature of reality like never before. You could build quantum computers, develop artificial intelligence, or increase human lifespan. You could even create a new life form. Or how about transitioning the world to clean energy? Or preserving the rainforests, or saving all endangered species? Maybe you could refreeze the melting Arctic, launch a new sustainable agricultural revolution, and reverse climate change? How to Spend a Trillion Dollars is the ultimate thought experiment but it is also a call to arms: these are all things we could do, if we put our minds to it - and our money.

Human civilization has evolved to the point at which we can consider tapping space resources and expanding beyond Earth's atmosphere. The Introduction surveys possible motivations for large-scale human emigration to space. Since our early ancestors began to move out of Africa, humans have constantly expanded their range. Today, the pattern of human settlement extends from pole to pole. Humans regularly visit the upper troposphere and ocean floor and technology has enabled a few to even reside above the atmosphere in space stations.

For the next few millennia at least (barring breakthroughs), the human frontier will include the solar system and the nearest stars. Will it better to settle the Moon, Mars, or a nearby asteroid and what environments can we expect to find in the vicinity of nearby stars are questions that need to be answered if mankind is to migrate into space.

Mysterious lights in the sky. Alien abductions. Government cover-ups. Dedicated ufologists have spent years documenting unexplained phenomena from flying saucers to extraterrestrial life. Uncover the history of UFOs in this illustrated guide, which separates the science fiction from the facts. The mysterious history of flying saucers is explored in-depth, from potential alien visitors as far back as Stonehenge to UFO cults and the secrets of Area 51. Adam Allsuch Boardman details in his signature graphic style the aircraft and artefacts associated with the search for the truth about UFOs.

The book examines applications in two disparate fields linked by the importance of valuing information: public health and space. Researchers in the health field have developed some of the most innovative methodologies for valuing information, used to help determine, for example, the value of diagnostics in informing patient treatment decisions. In the field of space, recent applications of value-of-information methods are critical for informing decisions on investment in satellites that collect data about air quality, fresh water supplies, climate and other natural and environmental resources affecting global health and quality of life.

Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight. The list of first/second authors includes M. Hapgood, N. Gopalswamy, K.D. Leka, G. Barnes, Yu. Yermolaev, P. Riley, S. Sharma, G. Lakhina, B. Tsurutani, C. Ngwira, A. Pulkkinen, J. Love, P.

This title analyzes distributed Earth observation missions from different perspectives. In particular, the issues arising when the payloads are distributed on different satellites are considered from both the theoretical and practical points of view. Moreover, the problems of designing, measuring, and controlling relative trajectories are thoroughly presented in relation to theory and applicable technologies. Then, the technological challenges to design satellites able to support such missions are tackled. An ample and detailed description of missions and studies complements the book subject.

This book analyses the rationale and history of space programs in countries of the developing world. Space was at one time the sole domain of the wealthiest developed countries. However, the last couple of decades of the twentieth century and the first decade of the twenty-first century have witnessed the number of countries with state-supported space programs blossom. Today, no less than twenty-five developing states, including the rapidly emerging economic powers of Brazil (seventh-largest), China (second-largest), and India (fourth-largest), possess active national space programs with already proven independent launch capability or concrete plans to achieve it soon. This work places these programs within the context of international relations theory and foreign policy analysis. The author categorizes each space program into tiers of development based not only on the level of technology utilised, but on how each fits within the country's overall national security and/or development policies. The text also places these programs into an historical context, which enables the author to demonstrate the logical thread of continuity in the political rationale for space capabilities generally. This book will be of much interest to students of space power and politics, development studies, strategic studies and international relations in general.

Hundreds of novels, films, and TV shows have speculated about what it would be like for us Earthlings to build cities on Mars. To make it a reality, however, these dreamers are in sore need of additional conceptual tools in their belt-particularly, a rich knowledge of city planning and design. Enter award-winning author and Tufts University professor, Justin Hollander. In this book, he draws on his experience as an urban planner and researcher of human settlements to provide a thoughtful exploration of what a city on Mars might actually look like. Exploring the residential, commercial, industrial, and infrastructure elements of such an outpost, the book is able to paint a vivid picture of how a Martian community would function - the layout of its public spaces, the arrangement of its buildings, its transportation network, and many more crucial aspects of daily life on another planet. Dr. Hollander then brings all these lessons to life through his own rendered plan for "Aleph," one of many possible designs for the first city on Mars. Featuring a plethora of detailed, cutting-edge illustrations and blueprints for Martian settlements, this book at once inspires and grounds the adventurous spirit. It is a novel addition to the current planning underway to colonize the Red Planet, providing a rich review of how we have historically overcome challenging environments and what the broader lessons of urban planning can offer to the extraordinary challenge of building a permanent settlement on Mars.

The development and exploration of space are technical engineering and scientific pursuits. However, politics determine which space programmes and projects are pursued, and establish cost, performance and schedule parameters for these ends. The goal of this volume is to provide an overview of the politics of space with regard to national space efforts, and the role played by national and international organizations. The Politics of Space: A Survey includes essays written by experts in the field, which explore a variety of issues, including the Politics of Space, National Security Space, Developed Space Programmes, Moderate Space Powers, Commercial Space Actors, International Organizations in Civil Space Affairs, Non-governmental Space Organizations and Public Sector Actors. Following the essays a comprehensive glossary of cross-referenced entries focuses on space organizations, including national space agencies, governmental organizations with a role in space, intergovernmental organizations, space and aerospace companies, satellite communications service companies and non-governmental organizations. Illustrations and documentation, comprising figures, tables and documentation on key issues of space politics are also included. Important figures include: models of space political processes; issues related to national security space management, challenges and environment; geopolitics of space; the dynamics of relations between the government and commercial space sectors. Tables of significance highlight programmatic attributes of national security space, comparisons in the development of space programmes among states worldwide, and the functions and roles of international organizations that deal with space. Documentation covers texts of space policy and law related to the regime of international space law, European space programmes and a number of other organizations.

The goals of the 10th International Space Conference on Protection of Materials and Structures from Space Environment ICPMSE-10J, since its inception in 1992, have been to facilitate exchanges between members of the various engineering and science disciplines involved in the development of space materials, including aspects of LEO, GEO and Deep Space environments, ground-based qualification, and in-flight experiments and lessons learned from operational vehicles that are closely interrelated to disciplines of the atmospheric sciences, solar-terrestrial interactions and space life sciences.

The knowledge of environmental conditions on and around the Moon, Mars, Venus and the low Earth orbit as well as other possible candidates for landing such as asteroids have become an important issue, and protecting both hardware and human life from the effects of space environments has taken on a new meaning in light of the increased interest in space travel and colonization of other planets.

And while many material experiments have been carried out on the ground and in open space in the last 50 years (LDEF, MEEP, SARE, MISSE, AOP, DSPSE, ESEM, EURECA, HST, MDIM, MIS, MPID, MPAC and SEED), many questions regarding the environmental impact of space on materials remain either poorly understood or unanswered. The coming generations of scientists will have to continue this work and tackle new challenges, continuing to build the level of confidence humans will need to continue the colonization of space. It is hoped that the proceedings of the ICPMSE-10J presented in this book will constitute a small contribution to doing so."

Every night, above our heads, a drama of epic proportions is playing out. Diamond planets, zombie stars, black holes heavier than a billion Suns. The cast of characters is extraordinary, and each one has its own incredible story to tell. We once thought of our Earth as unique, but we have now discovered thousands of alien planets, and that's barely a fraction of the worlds that are out there. And there are more stars in the Universe than grains of sand on every planet in the Solar System. But amid all this vastness, the Milky Way Galaxy, our Sun and the Earth are home to the only known life in the Universe - at least for now. With a foreword from Professor Brian Cox, and access to all the latest stunning NASA photography, Andrew Cohen takes readers on a voyage of discovery, via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding Universe, which holds clues to the biggest mystery of all - how did it all begin? We now know more about those first moments of existence than we ever thought possible, and hidden in this story of how it all began are the clues to the fate of the Universe itself and everything in it.

Since the Cold War, outer space has become of strategic importance for nations looking to seize the ultimate high ground. World powers establishing a presence there must consider, among other things, how they will conduct warfare in orbit. Leaders must dispense with "Buck Rogers" notions about operations in space and realize that policies there will have serious ramifications for their success in geopolitics. How should nations view space? How should they fight there? What would space warfare look like and how should strategists approach it? Offering critical observations regarding this unique theater of international relations, a military professional explores the strategic implications as human affairs move beyond Earth's atmosphere.
