Most amateur astronomers and many of those with similar interests but who are not currently practising observers have only a sketchy understanding of space flight. This book provides an introduction to its mechanics. The beauty of this book, written by an engineer who is also an accomplished science writer, is that it covers the subject comprehensively, and yet is almost entirely descriptive and non-mathematical. It deals with all aspects of space flight, from how to leave the Earth (including the design of the rocket, mission planning, navigation and communication), to life in space and the effects of weightlessness. The book also includes sections describing how an amateur can track satellites and understand their orbital parameters.

Joan Johnson-Freese argues that the race for space weapons and the U.S. quest for exclusive or at least dominant ownership of strategic space assets have alienated the very allies that the United States needs in order to maintain its leading role in space exploration. Taking a balanced look at the issues that have contributed to the decline of America's manned space program, such as lack of political support and funding, Johnson-Freese offers not only a critique but also a plan for enhancing U.S. space security through cooperation rather than competition.

She begins with a brief overview of the history of international space development through four eras: before "Sputnik," the space race, after Apollo, and globalization. Then she focuses on how policy changes of the mid-1990s have changed the nation, examining why the United States has grown obsessed with the development of space technology not just as a tool for globalization but as a route toward expanding an already dominant arsenal of weapons. Johnson-Freese claims that these policy choices have greatly affected the attitudes and actions of other countries, and in the fight to achieve security, the United States has instead put itself at greater peril.

Johnson-Freese explains complex technical issues in clear, accessible terms and suggests a way forward that is comprehensive rather than partisan. America is not the only country with space ambitions, but it is unique in viewing space as a battlefield and the technological advancements of other nations as a dire threat. Urgent and persuasive, "Space as a Strategic Asset" underscores the danger of allowing our space program to languish and the crucial role of cooperation in protecting the security of our country and the world.

The investigation of minor solar system bodies, such as comets and asteroids, using spacecraft requires an understanding of orbital motion in strongly perturbed environments. The solutions to a wide range of complex and challenging problems in this field are reviewed in this comprehensive and authoritative work.

Eclipses have captured attention and sparked curiosity about the cosmos since the first appearance of humankind. Having been blamed for everything from natural disasters to the fall of kings, they are now invaluable tools for understanding many celestial as well as terrestrial phenomena. This clear, easy-to-understand guide explains what causes total eclipses and how they can be used in experiments to examine everything from the dust between the planets to general relativity. A new chapter has been added on the eclipse of July 11, 1991 (the great Hawaiian eclipse).

When Ronald Reagan was elected in 1980, limits on NASA funding and the lack of direction under the Nixon and Carter administrations had left the U.S. space program at a crossroads. In contrast to his predecessors, Reagan saw outer space as humanity's final frontier and as an opportunity for global leadership. His optimism and belief in American exceptionalism guided a decade of U.S. activities in space, including bringing the space shuttle into operation, dealing with the 1986 Challenger accident and its aftermath, committing to a permanently crewed space station, encouraging private sector space efforts, and fostering international space partnerships with both U.S. allies and with the Soviet Union. Drawing from a trove of declassified primary source materials and oral history interviews, John M. Logsdon provides the first comprehensive account of Reagan's civilian and commercial space policies during his eight years in the White House. Even as a fiscal conservative who was hesitant to increase NASA's budget, Reagan's enthusiasm for the space program made him perhaps the most pro-space president in American history.

Fundamentals of Space Systems was developed to satisfy two objectives: the first is to provide a text suitable for use in an advanced undergraduate or beginning graduate course in both space systems engineering and space system design. The second is to be a primer and reference book for space professionals wishing to broaden their capabilities to develop, manage the development, or operate space systems. The authors of the individual chapters are practicing engineers that have had extensive experience in developing sophisticated experimental and operational spacecraft systems in addition to having experience teaching the subject material. The text presents the fundamentals of all the subsystems of a spacecraft missions and includes illustrative examples drawn from actual experience to enhance the learning experience. It includes a chapter on each of the relevant major disciplines and subsystems including space systems engineering, space environment, astrodynamics, propulsion and flight mechanics, attitude determination and control, power systems, thermal control, configuration management and structures, communications, command and telemetry, data processing, embedded flight software, survuvability and reliability, integration and test, mission operations, and the initial conceptual design of a typical small spacecraft mission.

Humanity has always looked to the stars, but it hasn't been until relatively recently that we have managed to travel into space. Carolyn Collins Petersen takes us on a journey from the first space pioneers and their work, through the First World War-led technological advances in rocketry that formed the basis for the Space Age, to the increasing corporate interest in space. This detailed examination of our steps into space is viewed from our potential future there - on Mars to be exact - and considers how we will reach that point. The author concludes with our current advances and our immediate ambitions in space exploration. The future and its scientific possibilities are enthralling: who will be the first to step on Mars? Will matter/antimatter annihilations take us to the Kuiper Belt, or will it be ion propulsion? What is the Alcubierre Warp Drive? Will it take us to the stars?

The N1 was the booster rocket for the Soviet manned moon program and was thus the direct counterpart of the Saturn V, the rocket that took American astronauts to the moon in 1969. Standing 345 feet tall, the N1 was the largest rocket ever built by the Soviets and was roughly the same height and weight as the Saturn. Though initially ahead of the US in the space race, the Soviets lagged behind as the pace for being first on the moon accelerated. Massive technical and personnel difficulties, plus spectacular failures, repeatedly delayed the N1 program. After the successful American landings on the moon, it was finally canceled without the N1 ever achieving orbit. The complete history of this rarely known Soviet program is presented here, starting in 1959, along with detailed technical descriptions of the N1's design and development. A full discussion of its attempted launches, disasters, and ultimate cancellation in 1974 completes this definitive history.

The two most fascinating questions about extraterrestrial life are where it is found and what it is like. In particular, from our Earth-based vantage point, we are keen to know where the closest life to us is, and how similar it might be to life on our home planet. This book deals with both of these key issues. It considers possible homes for life, with a focus on Earth-like exoplanets. And it examines the possibility that life elsewhere might be similar to life here, due to the existence of parallel environments, which may result in Darwinian selection producing parallel trees of life between one planet and another. Understanding Life in the Universe provides an engaging and myth-busting overview for any reader interested in the existence and nature of extraterrestrial life, and the realistic possibility of discovering credible evidence for it in the near future.

The objective of this textbook is to provide the mathematical models and algorithms needed to develop a thorough understanding of all control system functions of a rigid body spacecraft. Relatively simple, but practically applicable algorithms are presented rather than recent advances. We try to avoid detailed and specialized issues that are of less importance for the fundamental understanding, such as detailed environment models, etc. Furthermore, control problems that can be cast in standard formulations and solved with existing methods are not treated here. Instead, we intend to provide an understanding of the principles, put them in an engineering context, and try to give all explanations as concise as possible. Besides conventional three-axis attitude control systems, the following topics are treated in this book:* Control of agile rotation maneuvers using control moment gyros * Precise pointing control with error classes for pointing instruments * Control systems with accelerometers and free-flying test masses, which provide low-disturbance or disturbance-free environments We believe that these topics are of considerable relevance for the design of future spacecraft control systems, especially in the field of science and Earth observation missions.

A History Today Book of the Year A world-renowned astronomer and an esteemed science writer make the provocative argument for space exploration without astronauts. Human journeys into space fill us with wonder. But the thrill of space travel for astronauts comes at enormous expense and is fraught with peril. As our robot explorers grow more competent, governments and corporations must ask, does our desire to send astronauts to the Moon and Mars justify the cost and danger? Donald Goldsmith and Martin Rees believe that beyond low-Earth orbit, space exploration should proceed without humans. In The End of Astronauts, Goldsmith and Rees weigh the benefits and risks of human exploration across the solar system. In space humans require air, food, and water, along with protection from potentially deadly radiation and high-energy particles, at a cost of more than ten times that of robotic exploration. Meanwhile, automated explorers have demonstrated the ability to investigate planetary surfaces efficiently and effectively, operating autonomously or under direction from Earth. Although Goldsmith and Rees are alert to the limits of artificial intelligence, they know that our robots steadily improve, while our bodies do not. Today a robot cannot equal a geologist's expertise, but by the time we land a geologist on Mars, this advantage will diminish significantly. Decades of research and experience, together with interviews with scientific authorities and former astronauts, offer convincing arguments that robots represent the future of space exploration. The End of Astronauts also examines how spacefaring AI might be regulated as corporations race to privatize the stars. We may eventually decide that humans belong in space despite the dangers and expense, but their paths will follow routes set by robots.
