This book provides an overview of the space sector in African countries, from a legal and policy point of view, analysing how the African Union's Space Policy and Strategy (ASPS) is implemented and highlighting the various space activities in each country. Against this backdrop, it investigates the ASPS, identifying its policy goals identified and discussing its strategy. Moreover, it explores the on-going regional cooperation programmes, the continent's leading space actors and their roles, and the space-related regional fora and organizations, reflecting on various initiatives, including the African Leadership Conference on Space Science and Technology for Sustainable Development (ALC), the Regional African Satellite Communications Organisation (RASCOM), and the African Resource Management Satellite Constellation (ARMS-C). As such, it is a valuable source of information on space capacities in African countries.

Mission Geometry: Orbit and Constellation Design and Management (OCDM) is the most complete treatment available for many elements of space mission design and astronautics.

OCDM discusses both the similarities and differences between orbit and altitude systems in terms of hardware, algorithms, design, and processing requirements. With the demand for reduced cost and the introduction of extensive on-board computing, what were once entirely separate disciplines have begun to merge. This volume will speed that process.

In all areas, OCDM is meant to be practical, with recommendations, insights, formulas, and numerical recipes based on 40 years of spaceflight experience from organizations worldwide. It is meant to be both a text and reference work that can be used by those entering the field and by senior engineers engaged in the design, analysis, construction, or on-orbit operations of orbit and attitude systems and components.

This textbook introduces the theories and practical procedures used in planetary spacecraft navigation. Written by a former member of NASA's Jet Propulsion Laboratory (JPL) navigation team, it delves into the mathematics behind modern digital navigation programs, as well as the numerous technological resources used by JPL as a key player in the field. In addition, the text offers an analysis of navigation theory application in recent missions, with the goal of showing students the relationship between navigation theory and the real-world orchestration of mission operations.

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.

A Vertical Empire provides a description of the British rocketry and space programme from the 1950s to 1970s, detailing the Medium Range Ballistic Missile Blue Streak and its conversion to a satellite launcher as part of the European Launcher Development Organisation (ELDO). This extensively revised second edition includes material only made available in the past ten years and the text is supplemented by numerous photographs, sketches and statistics. The all-British satellite Black Arrow is described, as well as the research rocket Black Knight, the Blue Steel missile and the rocket powered interceptor aircraft.

Why, today, would anyone undertake a plan to launch a spacecraft some 30 years in the future, and on a journey that would take some 40 years to complete? Paul Gilster investigates the science, and the spirit, of the NASA and JPL researchers who are actually at work on just such a project.

From the reviews:

"Gilster introduces the challenges of imagining and planning interstellar exploration by leading readers through the difficulties of reaching and exploring the nearest bright star, Alpha Centauri. Seeded by ideas and concepts of the late Robert Forward, the narrative is framed as a learning process undertaken simultaneously by writer and reader. Although Alpha Centauri is astronomically nearby, a postulated trip by robot spacecraft, followed by manned exploration, would take 50 to 1,000 years, depending on the type of spacecraft propulsion used. Various methods for interstellar travel are introduced and discussed, including solar sails that use the power of starlight, nuclear fusion, antimatter hybrid systems, and beamed laser propulsion. One challenge is to get there in a reasonable time so that funding support, public interest, and events on Earth will not divert attention from the mission. Another challenge is timing the mission relative to available technology, because with better technology it might be possible to send a later robot on the same mission in less time. The book has no figures, tables, or illustrations but does include 30 pages of notes and an adequate 14-page index. Though the concepts presented are often fanciful, this book will appeal to readers who wonder about the future of exploration beyond the solar system. Summing Up: Highly recommended. Generalreaders; professionals." (W. E. Howard III, CHOICE, March 2005)

In the span of a single lifetime, light pollution stemming from Artificial Light At Night (ALAN) has severed our connection with the stars that we've had since the dawn of time. With the nocturnal biosphere significantly altered, light's anthropogenic influence has compelled millions of people to seek out the last remaining dark skies. This book explores the burgeoning growth of the astrotourism market, identifies star seeker trends, how the stars have shaped civilizations, and the budding space tourism industry. Discover ways to develop a destination for those who will cater to the astrotourist, share the night with guests, how to find customers, and the 2024 Great North American Eclipse. Meteor storms, eclipses, auroras, and other celestial phenomena have lured travellers for years. Here, the author expands the field of astrotourism with the inclusion of astronomical clocks, megaliths, and sundials, which are used to track the movement of the stars.

Around the world, NASA (National Aeronautics and Space Administration) is synonymous with air and space flight. This book covers NASA's aerospaceresearch from the agency's beginnings as NACA (National Advisory Committee for Aeronautics) in 1915 to the present-day NASA. Exciting projects and developments are portrayed, such as the first supersonic flight of the X-1 in 1947, the flights of the fastest manned aircraft, the rocket-powered X-15, which attained almost seven times the speed of sound in 1967, the flight-testing of the lunar module for the moon landings, tipping-rotor aircraft, testing new wing concepts, and much more. The emphasis of the book is in the realm of aviation research, but the boundaries between air and space research are often fluid, so that the development of the Space Shuttle and its testing have been included in this book. Besides project portrayals and descriptions of various research trends, the development sites and important personnel of NASA are portrayed.

This critical study of NASA's space shuttle program provides an in-depth examination of the events, decisions, and policies that may have contributed to the horrific destruction of the shuttles Challenger and Columbia. It first traces the early development of NASA's shuttle program, specifically examining the problems associated with the designs of shuttles OV-099 (which was to become Challenger) and OV-102 (which was to become Columbia). The reader is then taken through a detailed look at the first successful flights made by Challenger and Columbia and the cancellation of top-secret Shuttle flight 51-C (which would have launched under nearly identical weather conditions as the ill-fated Challenger). An in-depth assessment of the shuttles' disastrous final launches follows, including detailed accounts of the post-flight search and rescue operations, the official investigations into each accident, and the impact of each disaster on the future of NASA's manned space program.

All typical and special modal and response analysis methods, applied within the frame of the design of spacecraft structures, are described in this book. It therefore addresses graduate students and engineers in the aerospace field.

This monograph addresses the legal and policy issues relating to the commercial exploitation of natural resources in outer space. It begins by establishing the economic necessity and technical feasibility of space mining today, an estimate of the financial commitments required, followed by a risk analysis of a commercial mining venture in space, identifying the economic and legal risks. This leads to the recognition that the legal risks must be minimised to enable such projects to be financed. This is followed by a discussion of the principles of international space law, particularly dealing with state responsibility and international liability, as well as some of the issues arising from space mining activities. Much detail is devoted to the analysis of the content of the common heritage of mankind doctrine. The monograph then attempts to balance such interests in creating a legal and policy compromise to create a new regulatory regime.

In this remarkable oral history, Slava Gerovitch presents interviews with the men and women who witnessed Soviet space efforts firsthand. Rather than comprising a "master narrative," these fascinating and varied accounts bring to light the often divergent perspectives, experiences, and institutional cultures that defined the Soviet space program.

In September 2011, the GRAIL mission launched two unmanned spacecraft to the Moon, which entered into lunar orbit on December 31, 2011 and January 1, 2012. They orbited the Moon until December 17, 2012, when they impacted the surface near the Moon's north pole. This book contains three review articles co-authored by the GRAIL Science Team and Guest Scientists that describe the reasons for the GRAIL mission, the development of the necessary technology, and the design of the mission to acquire the most precise measurements of the lunar gravity field possible today. The book provides a detailed description of the GRAIL mission's scientific objectives, the instrumentation and its required performance, the complex simulation of the measurement system for determining the gravity field, and the innovative education and public outreach of the mission directed toward middle-school students who could select areas of the Moon for imaging with the onboard MoonKam camera system. This volume is aimed at researchers and graduate students active in solar system science and planetology. Originally published in Space Science Reviews journal, Vol. 178/1, 2013.

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 explores Russia's stunning success of ushering in the space age by launching Sputnik and beating the United States into space. It also examines the formation of NASA, the race for human exploration of the moon, the reality of global satellite communications, and a new generation of scientific spacecraft that began exploring the universe. An introductory essay by Pulitzer Prize winner Walter A. McDougall sets the context for Sputnik and its significance at the end of the twentieth century.

This book describes a feasible means of constructing such a reflector, as well as simple, reliable and low-cost structures for television and radio transmissions, debris removal from space and the development of solar sails for interplanetary missions. The aim of this book is thus to provide a comprehensive overview of the research in the technology of such space based structures expanded by centrifugal forces.
The most promising concepts and design solutions for different applications are addressed. Particular emphasis is placed on deployment dynamics of space-based structures and their retrieval techniques: the reorientation of expanded film sheets in space, selecting film folding patterns, tethering systems, and deployment mechanisms, and controlling the deployment-retrieval process by space vehicles. Also featured are sections on ground and orbital simulation.

Winner of the Nebraska Book Award What’s it like to travel at more than 850 MPH, riding in a supersonic T-38 twin turbojet engine airplane? What happens when the space station toilet breaks? How do astronauts “take out the trash� on a spacewalk, tightly encapsulated in a space suit with just a few layers of fabric and Kevlar between them and the unforgiving vacuum of outer space? The Ordinary Spaceman puts you in the flight suit of U.S. astronaut Clayton C. Anderson and takes you on the journey of this small-town boy from Nebraska who spent 167 days living and working on the International Space Station, including nearly forty hours of space walks. Having applied to NASA fifteen times over fifteen years to become an astronaut before his ultimate selection, Anderson offers a unique perspective on his life as a veteran space flier, one characterized by humility and perseverance.  From the application process to launch aboard the space shuttle Atlantis, from serving as a family escort for the ill-fated Columbia crew in 2003 to his own daily struggles—family separation, competitive battles to win coveted flight assignments, the stress of a highly visible job, and the ever-present risk of having to make the ultimate sacrifice—Anderson shares the full range of his experiences. With a mix of levity and gravitas, Anderson gives an authentic view of the highs and the lows, the triumphs and the tragedies of life as a NASA astronaut.

The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers.

It is well established and appreciated by now that more than 99% of the baryonic matter in the universe is in the plasma state. Most astrophysical systems could be approximated as conducting fluids in a gravitational field. It is the combined effect of these two that gives rise to the mind boggling variety of configurations in the form of filaments, loops, jets and arches. The plasma structures that cannot last for more than a second or less in a laboratory remain intact for astronomical time and spatial scales in an astrophysical setting. The case in point is the well known extragalactic jets whose collimation and stability has remained an enigma inspite of the efforts of many for many long years. The high energy radiation sources such as the active galactic nuclei again summon the coherent plasma radiation processes for their exceptionally large output from regions of relatively small physical sizes. The generation of magnetic field, anomalous transport of angular momentum with decisive bearing on star formation processes, the ubiquitous MHD turbulence under conditions irreproducible in terrestrial laboratories are some of the generic issues still awaiting a concerted effort for their understanding. Quantum Plasmas, pair plasmas and pair-ion plasmas exist under extreme conditions in planetary interiors and exotic stars. In this workshop plasma physicists, astrophysicists and plasma astrophysicists are brought together to discuss these issues.
