This book presents theoretical explorations of several fundamental problems in the dynamics and control of flexible beam systems. By integrating fresh concepts and results to form a systematic approach to control, it establishes a basic theoretical framework. It includes typical control design examples verified using MATLAB simulation, which in turn illustrate the successful practical applications of active vibration control theory for flexible beam systems. The book is primarily intended for researchers and engineers in the control system and mechanical engineering community, offering them a unique resource.

This volume presents a selection of advanced case studies that address a substantial range of issues and challenges arising in space engineering. The contributing authors are well-recognized researchers and practitioners in space engineering and in applied optimization.

The key mathematical modeling and numerical solution aspects of each application case study are presented in sufficient detail. Classic and more recent space engineering problems including cargo accommodation and object placement, flight control of satellites, integrated design and trajectory optimization, interplanetary transfers with deep space manoeuvres, low energy transfers, magnetic cleanliness modeling, propulsion system design, sensor system placement, systems engineering, space traffic logistics, and trajectory optimization are discussed. Novel points of view related to computational global optimization and optimal control, and to multidisciplinary design optimization are also given proper emphasis. A particular attention is paid also to scenarios expected in the context of future interplanetary explorations.

"Modeling and Optimization in Space Engineering" will benefit researchers and practitioners working on space engineering applications. Academics, graduate and post-graduate students in the fields of aerospace and other engineering, applied mathematics, operations research and optimal control will also find the book useful, since it discusses a range of advanced model development and solution techniques and tools in the context of real-world applications and new challenges."

This book presents recent results on the modelling of space plasmas with Kappa distributions and their interpretation. Hot and dilute space plasmas most often do not reach thermal equilibrium, their dynamics being essentially conditioned by the kinetic effects of plasma particles, i.e., electrons, protons, and heavier ions. Deviations from thermal equilibrium shown by these plasma particles are often described by Kappa distributions. Although well-known, these distributions are still controversial in achieving a statistical characterization and a physical interpretation of non-equilibrium plasmas. The results of the Kappa modelling presented here mark a significant progress with respect to all these aspects and open perspectives to understanding the high-resolution data collected by the new generation of telescopes and spacecraft missions. The book is directed to the large community of plasma astrophysics, including graduate students and specialists from associated disciplines, given the palette of the proposed topics reaching from applications to the solar atmosphere and the solar wind, via linear and quasilinear modelling of multi-species plasmas and waves within, to the fundamental physics of nonequilibrium plasmas.

This book describes and contextualises collisionless plasma theory, and in particular collisionless plasma equilibria. The Vlasov-Maxwell theory of collisionless plasmas is an increasingly important tool for modern plasma physics research: our ability to sustain plasma in a steady-state, and to mitigate instabilities, determines the success of thermonuclear fusion power plants on Earth; and our understanding of plasma aids in the prediction and mitigation of Space Weather effects on terrestrial environments and satellites. Further afield, magnetic reconnection is a ubiquitous energy release mechanism throughout the Universe, and modern satellites are now able to make in-situ measurements with kinetic scale resolution. To keep pace with these challenges and technological developments, a modern scientific discussion of plasma physics must enhance, and exploit, its 'literacy' in kinetic theory. For example, accurate analytical calculations and computer simulations of kinetic instabilities are predicated on a knowledge of Vlasov-Maxwell equilibria as an initial condition. This book highlights new fundamental work on Vlasov-Maxwell equilibria, of potential interest to mathematicians and physicists alike. Possible applications involve two of the most significant magnetic structures known to confine plasma and store energy: current sheets and flux tubes.

The articles in this volume cover, for the first time, all aspects of planetary magnetism, from the observations made by space missions to their interpretation in terms of the properties of all the planets in the solar system. Studies of dynamo-generated magnetic fields in Mercury, the Earth, the giant planets, as well as in Ganymede, one of Jupiter's moons, are presented. Crustal magnetic field in Mars, the Mon and the Earth are described as well as magnetic fields induced in the solar system bodies. There are several articles dealing with dynamo theory and modelling and applications to the different planets.

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.

This set of lectures collects surveys of open problems in celestial dynamics and dynamical astronomy applied to solar, extra-solar and galactic systems. The discovery and thus the possibility to study many new extra-solar planetary systems have spurred new developments in the field and enabled the testing and enlargement of the domains of validity of theoretical predictions through the Nekhoroshev theorem.

The space between the stars contains a large diversity of objects in which physical processes occur that are fundamental to the structure and evolution of galaxies. This book offers the reader a basic knowledge of these processes and presents simple numeric estimates of the main quantities relevant to the interstellar medium. The main objects that constitute the interstellar space are described, but the emphasis of the book lies in the physical processes occurring in these objects, which may also occur in other astrophysical environments. The book is directed tor graduate as well as advanced undergraduate students of physics and astrophysics.

This book provides the latest scientific understanding of the Sun, sharing insights gleaned from the international solar physics project Hinode. The authors (who are the main project contributors) review, from the various viewpoints, the discoveries and advances made by the on-orbit operations of the Hinode spacecraft in its first decade. Further, they present a wealth of scientifically important photographs and data from Hinode. Launched in September 2006, Hinode is the third Japanese solar observatory on orbit, and employs three highly advanced telescopes jointly developed and operated with international partners. The book describes the background of these research topics, how the Hinode telescopes have tackled various challenges, and the scientific achievements and impacts in the first 10 years. Furthermore, it explores future perspective of researches in Japan. The book will benefit undergraduate students interested in recent advance in the solar research, as well as graduate students and researchers working in solar physics, the space sciences, astronomy, and plasma physics.

The book analyzes the various legal and political concepts to resolve the problem of the existing space debris in outer space and which measures have been taken to avoid space debris or to reduce potential space debris in the course of future space missions. From a scientific and technical point of view various studies are ongoing to analyze the feasibility of active debris removal. Nevertheless it has to be highlighted that outer space is an international area where various actors with different legal and political concepts are operating, a situation that leads to different approaches concerning such activities.

Praise for the first edition: "A terrific blend of the science and the history." Martha Haynes, Goldwin Smith Professor of Astronomy, Cornell University, New York, USA "The book is a treat... Highly recommended for public and academic libraries." Peter Hepburn, now Head Librarian, College of the Canyons, Santa Clarita, California, USA Today, we recognize that we live on a planet circling the sun, that our sun is just one of billions of stars in the galaxy we call the Milky Way, and that our galaxy is but one of billions born out of the Big Bang. Yet, as recently as the early twentieth century, the general public and even astronomers had vague and confused notions about what lay beyond the visible stars. Can we see to the edge of the universe? Do we live in a system that would look, from a distance, like a spiral nebula? This fully updated second edition of Minding the Heavens: The Story of Our Discovery of the Milky Way explores how we learned that we live in a galaxy, in a universe composed of galaxies and unseen, mysterious dark matter. The story unfolds through short biographies of seven astronomers: Thomas Wright, William Herschel, and Wilhelm Struve of the eighteenth and nineteenth centuries; the transitional figure of William Huggins; and Jacobus Kapteyn, Harlow Shapley, and Edwin Hubble of the modern, big-telescope era. Each contributed key insights to our present understanding of where we live in the cosmos, and each was directly inspired by the work of his predecessors to decipher "the construction of the heavens." Along the way, the narrative weaves in the contributions of those in supportive roles, including Caroline Herschel-William's sister, and the first woman paid to do astronomy-and Martha Shapley, a mathematician in her own right who carried out calculations for her spouse. Through this historical perspective, readers will gain a new appreciation of our magnificent Milky Way galaxy and of the beauties of the night sky, from ghostly nebulae to sparkling star clusters. Features: Fully updated throughout to reflect the latest in our understanding of the Milky Way, from our central supermassive black hole to the prospect of future mergers with other galaxies in our Local Group. Explains the significance of current research, including from the Gaia mission mapping our galaxy in unprecedented detail. Unique and broadly appealing approach. A biographical framework and ample illustrations lead the reader by easy, enjoyable steps to a well-rounded understanding of the history of astronomy. Leila Belkora (Ph.D., Astrophysics) is a science writer. She earned her doctorate from the University of Colorado-Boulder, specializing in solar radio astronomy. She has previously taught university physics, astronomy, and communication for engineers. She lives in Southern California and enjoys local astronomy outreach activities.

This open access book provides a comprehensive toolbox of analysis techniques for ionospheric multi-satellite missions. The immediate need for this volume was motivated by the ongoing ESA Swarm satellite mission, but the tools that are described are general and can be used for any future ionospheric multi-satellite mission with comparable instrumentation. In addition to researching the immediate plasma environment and its coupling to other regions, such a mission aims to study the Earth's main magnetic field and its anomalies caused by core, mantle, or crustal sources. The parameters for carrying out this kind of work are examined in these chapters. Besides currents, electric fields, and plasma convection, these parameters include ionospheric conductance, Joule heating, neutral gas densities, and neutral winds.

Former NASA Astronaut Harrison Schmitt advocates a private, investor-based approach to returning humans to the Moon-to extract Helium 3 for energy production, to use the Moon as a platform for science and manufacturing, and to establish permanent human colonies there in a kind of stepping stone community on the way to deeper space. With governments playing a supporting role-just as they have in the development of modern commercial aeronautics and agricultural production-Schmitt believes that a fundamentally private enterprise is the only type of organization capable of sustaining such an effort and, eventually, even making it pay off.

This book provides an introduction, from the astronomical point of view of the author, to the exciting search for extra-terrestrial life, and an overview of the current status of research into 'alien' life in the Solar System and beyond. It also explores the potential future human exploration of the Moon and Mars. Up-to-date with the latest developments in the field and accompanied by key references for further study, it is a fantastic introduction to the field of astrobiology for non-science majors taking an elective module, in addition to undergraduates studying physics with an interest in this area. Features: Contains the latest groundbreaking research in the hunt for life outside of Earth Discusses the identification of biosignatures in exo-planets Reviews future options for human outposts on the Moon and Mars

This book discusses all spacecraft attitude control-related topics: spacecraft (including attitude measurements, actuator, and disturbance torques), modeling, spacecraft attitude determination and estimation, and spacecraft attitude controls. Unlike other books addressing these topics, this book focuses on quaternion-based methods because of its many merits. The book lays a brief, but necessary background on rotation sequence representations and frequently used reference frames that form the foundation of spacecraft attitude description. It then discusses the fundamentals of attitude determination using vector measurements, various efficient (including very recently developed) attitude determination algorithms, and the instruments and methods of popular vector measurements. With available attitude measurements, attitude control designs for inertial point and nadir pointing are presented in terms of required torques which are independent of actuators in use. Given the required control torques, some actuators are not able to generate the accurate control torques, therefore, spacecraft attitude control design methods with achievable torques for these actuators (for example, magnetic torque bars and control moment gyros) are provided. Some rigorous controllability results are provided. The book also includes attitude control in some special maneuvers, such as orbital-raising, docking and rendezvous, that are normally not discussed in similar books. Almost all design methods are based on state-spaced modern control approaches, such as linear quadratic optimal control, robust pole assignment control, model predictive control, and gain scheduling control. Applications of these methods to spacecraft attitude control problems are provided. Appendices are provided for readers who are not familiar with these topics.

This book is the first comprehensive source for the Space Politics and Policies of the United States Civil, Military, Intelligence, and Commercial Space Programs.

Space Politics and Policy: An Evolutionary Perspective provides a comprehensive survey of Space Policy. This book is organized around two themes. Space Policy is evolutionary in that it has responded to dramatic political events, such as the launching of Sputnik and the Cold War, and has undergone dynamic and evolutionary policy changes over the course of the space age. Space Policy is an integral part of and interacts with public policy processes in the United States and abroad.

The book analyzes Space Policy at several levels including historical context, political actors and institutions, political processes and policy outcomes. It examines the symbiotic relationships between policy, technology, and science; provides a review and synthesis of the existing body of knowledge in Space Policy; and identifies Space Policy trends and developments from the beginnings of the space age through the current era of the twenty-first century.

The book is intended for those interested in Space Policy, especially Space Policy decision-makers, program and project managers, as well as students and lecturers of Space Policy.

This book provides detailed insights into how space and its applications are, and can be, used to support the development of the full range and diversity of African societies, as encapsulated in the African Union's Agenda 2063. Like previous books in the "Southern Space Studies" series, it focuses on the role of space in supporting the UN Sustainable Development Goals in Africa, but it covers an even more extensive array of relevant and timely topics addressing all facets of African development. It demonstrates that, while great achievements have been made in recent years in terms of economic and social development, which has lifted many of Africa's people out of poverty, there is still much that needs to be done to fulfill the basic needs of Africa's citizens and afford them the dignity they deserve: to this end space is already being employed in diverse fields of human endeavor to serve Africa's goals for its future, but there is much room for further incorporation of space systems and data. Providing a comprehensive overview of the role space is playing in achieving Africa's developmental aspirations, the book is of great interest to both students and professionals in fields such as space studies, international relations, governance, social and rural development, and many others.
