This is a long-overdue volume dedicated to space trajectory optimization. Interest in the subject has grown, as space missions of increasing levels of sophistication, complexity, and scientific return - hardly imaginable in the 1960s - have been designed and flown. Although the basic tools of optimization theory remain an accepted canon, there has been a revolution in the manner in which they are applied and in the development of numerical optimization. This volume purposely includes a variety of both analytical and numerical approaches to trajectory optimization. The choice of authors has been guided by the editor's intention to assemble the most expert and active researchers in the various specialities presented. The authors were given considerable freedom to choose their subjects, and although this may yield a somewhat eclectic volume, it also yields chapters written with palpable enthusiasm and relevance to contemporary problems.

This book is a rich source of information on design research and solutions for the support and development of space missions. International experiences and researches are presented in order to cast light on the role of space design in improving living and working conditions in outer space and to highlight the particularities of the necessary design skills, taking into account specific requirements and constraints. The challenge facing designers is how to approach environmentally extreme conditions in such a way that they are transformed from limitations into opportunities. The author has herself developed products that have been tested during on-orbit experiments on the International Space Station. Drawing on this unique experience and other case studies, the author proposes a new design methodology for space and demonstrates how the discipline of design is able to generate innovation thanks to the strong capacity of visioning. Ultimately this will lead to the development of further new equipment for astronauts that will facilitate space travel. While the book is intended primarily for students and researchers, it is also of interest for a broad readership attracted by space, innovation, and future scenarios.

At the intersection of astronautics, computer science, and social science, this book introduces the challenges and insights associated with computer simulation of human society in outer space, and of the dynamics of terrestrial enthusiasm for space exploration. Never before have so many dynamic representations of space-related social systems existed, some deeply analyzing the logical implications of social-scientific theories, and others open for experience by the general public as computer-generated virtual worlds. Fascinating software ranges from multi-agent artificial intelligence models of civilization, to space-oriented massively multiplayer online games, to educational programs suitable for schools or even for the world's space exploration agencies. At the present time, when actual forays by humans into space are scarce, computer simulations of space societies are an excellent way to prepare for a renaissance of exploration beyond the bounds of Earth.

This book considers two key educational tools for future generations of professionals with a space architecture background in the 21st century: (1) introducing the discipline of space architecture into the space system engineering curricula; and (2) developing space architecture as a distinct, complete training curriculum. Professionals educated this way will help shift focus from solely engineering-driven transportation systems and "sortie" missions towards permanent off-world human presence. The architectural training teaches young professionals to operate at all scales from the "overall picture" down to the smallest details, to provide directive intention-not just analysis-to design opportunities, to address the relationship between human behavior and the built environment, and to interact with many diverse fields and disciplines throughout the project lifecycle. This book will benefit individuals and organizations responsible for planning transportation and habitat systems in space, while also providing detailed information on work and design processes for architects and engineers.

The subject of wave-particle interactions occurring in space plasmas has developed strongly, both observationally and theoretically, since the discovery of the Van Allen radiation belts of charged particles trapped in the Earth s magnetosphere over forty years ago. These wave-particle interactions are recognized today as being a most important research topic in space plasma physics. This is the first book to provide a full and systematic description of the physical theory of whistler and Alfv n cyclotron masers acting in planetary magnetospheres, and in the Sun s outer atmosphere. It addresses current research topics by examining significant problems in the subject. It gives sufficient detail on the topic that readers use to apply the methods presented to new problems, helping them with their own research. This book is a valuable reference for researchers and graduate students working in space science, solar-terrestrial physics, plasma physics, and planetary sciences.

This book explores creative solutions to the unique challenges inherent in crafting livable spaces in extra-terrestrial environments. The goal is to foster a constructive dialogue between the researchers and planners of future (space) habitats. The authors explore the diverse concepts of the term Habitability from the perspectives of the inhabitants as well as the planners and social sciences. The book provides an overview of the evolution and advancements of designed living spaces for manned space craft, as well as analogue research and simulation facilities in extreme environments on Earth. It highlights how various current and future concepts of Habitability have been translated into design and which ones are still missing. The main emphasis of this book is to identify the important factors that will provide for well-being in our future space environments and promote creative solutions to achieving living spaces where humans can thrive. Selected aspects are discussed from a socio-spatial professional background and possible applications are illustrated. Human factors and habitability design are important topics for all working and living spaces. For space exploration, they are vital. While human factors and certain habitability issues have been integrated into the design process of manned spacecraft, there is a crucial need to move from mere survivability to factors that support thriving. As of today, the risk of an incompatible vehicle or habitat design has already been identified by NASA as recognized key risk to human health and performance in space. Habitability and human factors will become even more important determinants for the design of future long-term and commercial space facilities as larger and more diverse groups occupy off-earth habitats. The book will not only benefit individuals and organizations responsible for manned space missions and mission simulators, but also provides relevant information to designers of terrestrial austere environments (e.g., remote operational and research facilities, hospitals, prisons, manufacturing). In addition it presents general insights on the socio-spatial relationship which is of interest to researchers of social sciences, engineers and architects.

Principles of Nuclear Rocket Propulsion provides an understanding of the physical principles underlying the design and operation of nuclear fission-based rocket engines. While there are numerous texts available describing rocket engine theory and nuclear reactor theory, this is the first book available describing the integration of the two subject areas. Most of the book's emphasis is primarily on nuclear thermal rocket engines, wherein the energy of a nuclear reactor is used to heat a propellant to high temperatures and then expel it through a nozzle to produce thrust. Other concepts are also touched upon such as a section devoted to the nuclear pulse rocket concept wherein the force of externally detonated nuclear explosions is used to accelerate a spacecraft. Future crewed space missions beyond low earth orbit will almost certainly require propulsion systems with performance levels exceeding that of today's best chemical engines. A likely candidate for that propulsion system is the solid core Nuclear Thermal Rocket or NTR. Solid core NTR engines are expected to have performance levels which significantly exceed that achievable by any currently conceivable chemical engine. The challenge is in the engineering details of the design which includes not only the thermal, fluid, and mechanical aspects always present in chemical rocket engine development, but also nuclear interactions and some unique materials restrictions.

"The Early Evolution of the Atmospheres of Terrestrial Planets" presents the main processes participating in the atmospheric evolution of terrestrial planets. A group of experts in the different fields provide an update of our current knowledge on this topic. Several papers in this book discuss the key role of nitrogen in the atmospheric evolution of terrestrial planets. The earliest setting and evolution of planetary atmospheres of terrestrial planets is directly associated with accretion, chemical differentiation, outgassing, stochastic impacts, and extremely high energy fluxes from their host stars. This book provides an overview of the present knowledge of the initial atmospheric composition of the terrestrial planets. Additionally it includes some papers about the current exoplanet discoveries and provides additional clues to our understanding of Earth's transition from a hot accretionary phase into a habitable world. All papers included were reviewed by experts in their respective fields. We are living in an epoch of important exoplanet discoveries, but current properties of these exoplanets do not match our scientific predictions using standard terrestrial planet models. This book deals with the main physio-chemical signatures and processes that could be useful to better understand the formation of rocky planets.

This book presents recent advances in the physics of magnetic reconnection, investigated via both in situ spacecraft observations and fully kinetic numerical simulations. Magnetic reconnection is a fundamental process in plasma physics during which the topological reconfiguration of the magnetic field leads to energy conversion and particle energization. The book focuses on the physics of the electron diffusion region (EDR), a crucial region where the electrons are decoupled from the magnetic field and efficiently accelerated by the electric field. By using recent, high-resolution measurements provided by NASA's Magnetospheric MultiScale Mission (MMS), the book investigates the structure of the EDR at the Earth's magnetopause. The presented analysis provides evidence for an inhomogeneous and patchy EDR structure. The structure of the EDR appears to be more complex than the in laminar picture suggested by previous observations and simulations. Then, electrons dynamics in the EDR is studied using a novel, fully kinetic Eulerian Vlasov-Darwin model that has been implemented in the Vlasov-DArwin numerical code (ViDA), explained in detail in the book. Lastly, the book covers the testing of this new code, and investigates the contributions of the different terms in the generalized Ohm's law within the EDR, highlighting the role of the electron inertia term.

This book is based on the findings, conclusions and recommendations of the Global Space Governance study commissioned by the 2014 Montreal Declaration that called upon civil society, academics, governments, the private sector, and other stakeholders to undertake an international interdisciplinary study. The study took three years to complete. It examines the drivers of space regulations and standards, key regulatory problems, and especially addresses possible improvements in global space governance. The world's leading experts led the drafting of chapters, with input from academics and knowledgeable professionals in the public and private sectors, intergovernmental organizations, and nongovernmental organizations from all the regions of the world with over 80 total participants. This book and areas identified for priority action are to be presented to the UN Committee on the Peaceful Uses of Outer Space and it is hoped will be considered directly or indirectly at the UNISPACE+50 event in Vienna, Austria, in 2018. The report, a collective work of all the contributors, includes objective analysis and frank statements expressed without pressure of political, national, and occupational concerns or interest. It is peer-reviewed and carefully edited to ensure its accuracy, preciseness, and readability. It is expected that the study and derivative recommendations will form the basis for deliberations and decisions at international conferences and meetings around the world on the theme of global space governance. This will hopefully include future discussion at the UN Committee on the Peaceful Uses of Outer Space.
