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 is a theoretical and practical guide on how to undertake and navigate advanced research in the arts, humanities and social sciences.

An exploration of emergent roles for design and the 21st century designer explored through the work of 21 research teams. Over a twelve-month period each of these groups held a series of workshops and events to examine different facets of future design activity. Each of the contributions describes the context of enquiry, the journey taken by the research team and key insights generated through discourse. Editor and Initiative Director, Tom Inns, provides an introductory chapter that suggests ways that the reader might navigate these different viewpoints.

The majority of the world's population now live in cities, nearly a quarter of which boast populations of one million or more. The rise of globalisation has granted cities unprecedented significance, both politically and economically, leading to benefits and problems at national and international levels. The Handbook of Emerging 21st-Century Cities explores the changes that are occurring in cities, and the impacts that they are having, at the local, national and global scale.

This first comprehensive survey of workplace design for the new century, this book captures emerging themes and ideas in office architecture and interiors around the world. Written and researched by the authors of The Creative Office, it advances the concept of increasing creativity in planning and design by exploring the new workplace models that are developing in response to rapid organisational, social and technological change. In the introduction the authors discuss how the new workplace of the 21st century is already exhibiting different spatial, organizational and material characteristics from the scientifically managed, process-driven, mechanistic model of the 20th century modern office. This is followed by four thematic chapters that illustrate the key new trends through 45 international case studies.

In a period of change, consolidation and cut-backs as well as rapid technological developments, the business school library is often at the forefront of new initiatives and innovative approaches to delivering and managing information in the most responsive yet cost-effective manner possible. In this unique book a respected group of business library directors from prestigious institutions around the world come together to reflect on the key challenges facing their libraries today, from change management to technology and communications to space. They document the state of the sector during a time of fundamental change, draw on their own local contexts to explore topics and concepts and share their insights into what the future might bring. This book will be essential reading not only for librarians working in business, management or social sciences disciplines but for all professionals managing library and information services.
