Space For The 21st Century

FOREWORD By Bruce McCandless II Former NASA Astronaut This volume is the fifth in the series on contemporary space topics by the Aerospace Technology Working Group with support from Secure World Foundation, the International Space University, and the International Institute of Space Commerce. It deals principally with the topic of sustainability of space operations. In all fields of challenging endeavor actually accomplishing an objective (e.g., putting a satellite into orbit) comes first, followed by exploitation or commercialization, and lastly by a realization that the resource is finite. Such "finite-ness" may come from considerations of pollution (e.g., space debris, propulsion effluent) or of actual limitations on the availability of the resource (e.g., crowding of Geostationary Earth Orbit - GEO). Both of these topics are among those discussed in detail in this volume. Developing countries, in particular, may find such considerations too burdensome, and this begs the need for regulation to avoid the classic "Tragedy of the Commons" situation. In the case of orbital debris we have collectively arrived at a point where tens of millions of tiny pieces of debris are currently in orbit, decaying at diverse rates in a situation where a single flake of paint has been demonstrated to be capable of causing damage when impacting at high relative velocities. At the other end of the spectrum, defunct satellites (e.g., ESA's Envisat) present discrete problems worthy of individual retrieval/disposal efforts but fraught with complications arising from ownership to potentially still effective ITAR constraints on access to onboard technology. And, of course, the managers of the International Space Station are absolutely paranoid about higher altitude orbital debris eventually decaying to and ultimately impacting their very large orbiting facility. While space may realistically be dubbed "infinite," very specific orbits, or sets of orbits, have practical capacity limits. In GEO, for example, spacing of satellites along it are subject to constraints arising from use of the same radio frequency spectra and the size of ground based antennas required to spatially discriminate between adjacent satellites. In popular high inclination sun-synchronous Earth imaging orbits, these all converge near the poles, creating a traffic management concern arising from the risk of collision. The subject of "green propellants" is treated from several aspects. The Liquid Oxygen / Liquid Hydrogen system, while yielding only water vapor from combustion, may have a significant carbon footprint associated with the manufacture of the LH2 from methane or methanol. Aluminum oxide, an exhaust product of common solid propellant boosters is generally regarded as inert, but the inhalation of fine particles of it can cause pulmonary fibrosis or other lung damage in humans. Additionally the need for oxidizer depletion shutdown in the family of hydrazine/oxidizer booster stages results in significant quantities of UDMH (for example) being dispersed upon impact of the early stages. No Foreword can do adequate justice to the carefully developed material within the publication itself. For a detailed and thought provoking coverage of the principal topics associated with the sustainability of space operations, this book is highly recommended, authoritative, and "a good read."

This book provides a series of new addresses to the enduring problem of how to categorize the Fantastic. The approach taken is through the lens of spatiality; the Fantastic gives us new worlds, although of course these are refractions of worlds already in being. In place of 'real' spaces (whatever they might be), the Fantastic gives us imaginary spaces, although within those spaces historical and cultural conflicts are played out, albeit in forms that stretch our understanding of everyday location, and our usual interpretations of cause and effect. Many authors are addressed here, from a variety of different geographical and national traditions, thus demonstrating how the Fantastic - as a mode, a genre, a way of thinking, imagining and writing - continually traverses borders and boundaries. We hope to move the ongoing debate about the Fantastic forward in a scholarly as well as an engaging way.

This book examines the recent shift in US space policy and the forces that continually draw the US back into a space-technology security dilemma. The dual-use nature of the vast majority of space technology, meaning of value to both civilian and military communities and being unable to differentiate offensive from defensive intent of military hardware, makes space an area particularly ripe for a security dilemma. In contrast to previous administrations, the Obama Administration has pursued a less militaristic space policy, instead employing a strategic restraint approach that stressed multilateral diplomacy to space challenges. The latter required international solutions and the United States, subsequently, even voiced support for an International Code of Conduct for Space. That policy held until the Chinese anti-satellite (ASAT) test in 2013, which demonstrated expanded Chinese capabilities. This volume explores the issues arising from evolving space capabilities across the world and the security challenges this poses. It subsequently discusses the complexity of the space environment and argues that all tools of national power must be used, with some degree of balance, toward addressing space challenges and achieving space goals. This book will be of much interest to students of space policy, defence studies, foreign policy, security studies and IR.

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.

Elementary readers will get a look into space exploration as they move through this fascinating nonfiction title. Readers will discover galaxies like the Milky Way, the effect gravity has on the inner and outer planets, comets, asteroids, constellations, and what measures scientists are taking to learn more about the vast body of the universe and more, including the Hubble Telescope and the Mars Rover. With vivid images, intriguing facts, informational text, a glossary, and a list of helpful websites, readers are encouraged to discover what they would explore in deep space! This 6-Pack includes six copies of this title and a lesson plan.

The nature of spatial imaginations has become central to a range of major social and political debates. Narratives on spatial inequality, from the North-South divide in global economic and political visions, to marginalisation and 'ghettoisation' in Western cities, appear regularly in our daily newspapers. Such examples indicate that issues of space/spatiality are as crucial in our current societies as never before. 'Space Odysseys' brings together leading social scientists including John Urry and Derek Gregory to address a number of central issues in spatiality and social relations in the early 21st century. Starting from the presupposition that space is a social dimension and a social construct, it then presents examples of these conceptions of space at work. While the book title's indirect reference to the film '2001: A Space Odyssey' indicates the contributors' interest in questions of voyages and mobility, the plural use shows that the approaches to this conceptual exploration are multiple, reflecting differences in experience, in social context and/or in gender, class and ethnicity. The book is divided into three main sections. The first explores issues of 'mobility, immobility and embodied narratives', the second section deals with 'territoriality, mobility and identity politics and the final section concludes with chapters on 'the spatial production of knowledge'.
