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.

An introduction to celestial mechanics for advanced undergraduates, graduate students, and researchers new to the field Celestial mechanics-the study of the movement of planets, satellites, and smaller bodies such as comets-is one of the oldest subjects in the physical sciences. Since the mid-twentieth century, the field has experienced a renaissance due to advances in space flight, digital computing, numerical mathematics, nonlinear dynamics, and chaos theory, and the discovery of exoplanets. This modern, authoritative introduction to planetary system dynamics reflects these recent developments and discoveries and is suitable for advanced undergraduate and graduate students as well as researchers. The book treats both traditional subjects, such as the two-body and three-body problems, lunar theory, and Hamiltonian perturbation theory, as well as a diverse range of other topics, including chaos in the solar system, comet dynamics, extrasolar planets, planetesimal dynamics, resonances, tidal friction and disruption, and more. The book provides readers with all the core concepts, tools, and methods needed to conduct research in the subject. Provides an authoritative introduction that reflects recent advances in the field Topics treated include Andoyer variables, co-orbital satellites and quasi-satellites, Hill's problem, the Milankovich equations, Colombo's top and Cassini states, the Yarkovsky and YORP effects, orbit determination for extrasolar planets, and more More than 100 end-of-book problems elaborate on concepts not fully covered in the main text Appendixes summarize the necessary background material Suitable for advanced undergraduates and graduate students; some knowledge of Hamiltonian mechanics and methods of mathematical physics (vectors, matrices, special functions, etc.) required Solutions manual available on request for instructors who adopt the book for a course

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?

In 1966 a group of highly respected aerospace engineers revealed that US scientists were perfecting ways to control gravity. They predicted a breakthrough would come by the end of the decade, ushering in an era of limitless, clean propulsion for a new breed of fuelless transport systems - and weapons beyond our imagination. Of course it never happened. Or did it? Forty years on a chance encounter with one of the engineers who made that prediction forces a highly sceptical aerospace and defence journalist, Nick Cook, to consider the possibility that America did indeed crack the gravity code - and has covered up ever since. His investigations moved from the corridors of NASA to the dark heartland of America's classified weapons establishment, where it became clear that a half century ago, in the dying days of the Third Reich, Nazi scientists were racing to perfect a Pandora's Box of high technology that would deliver Germany from defeat.

History says that they failed. But the trail that takes Cook deep into the once-impenetrable empire of SS General Hans Kammler - the man charged by Adolf Hitler with perfecting German secret weapons technology - says otherwise. In his pursuit of Kammler, Cook finally establishes the truth: America is determined to hang onto its secrets, but the stakes are enormous and others are now in the race to acquire a suppressed technology.

Most people just accept that our universe is ruled by gravity; an assumption that is wrong. Evidence instead shows that the force responsible for all of the objects and events we observe throughout the universe is the electric force that enables current flow and therefore magnetic fields to exist. If we consider that the electric force is fundamentally one thousand, billion, billion, billion, billion times more powerful than gravity and that the universe consists of 99.99% plasma; charged matter through which electric currents flow, then you have good reason to open your mind and read what this book has to say.

Featured on NPR and PBS's SciTech Now, and in Fast Company, Forbes, and the Wall Street Journal The inside story of the new race to conquer space For the outsize personalities staking their fortunes on spaceships, the new race to explore space could be a dead end, a lucrative opportunity--or the key to humanity's survival. Elon Musk and Jeff Bezos take center stage in this fast-paced narrative as they attempt to disrupt the space economy and feed their own egos. We meet a supporting cast of equally fascinating entrepreneurs, from the irrepressible British mogul Richard Branson to the satellite internet visionary Greg Wyler. Tim Fernholz's fly-on-the-wall reporting captures an industry in the midst of disruption. NASA seeks to preserve its ambitious space program, traditional aerospace firms like Boeing and Lockheed Martin scramble to adapt to new competitors, lobbyists tussle over public funds, and lawmakers try to prevent this new space race from sparking global conflict. Fernholz spins this high-stakes marathon into a riveting tale of rivalry and survival.

For operating in severe environments, long life and reliability, radioisotope power systems have proven to be the most successful of all space power sources. Two Voyager missions launched in 1977 to study Jupiter, Saturn, Uranus, Neptune, and their satellites, rings and magnetic fields and continuing to the heliosphere region are still functioning over thirty years later. Radioisotope power systems have been used on the Moon, exploring the planets, and exiting our solar system. There success is a tribute to the outstanding engineering, quality control and attention to details that went into the design and production of radioisotope power generation units. Space nuclear radioisotope systems take the form of using the thermal energy from the decay of radioisotopes and converting this energy to electric power. Reliability and safety are of prime importance. Mission success depends on the ability of being able to safely launch the systems and on having sufficient electrical power over the life of the mission. Graceful power degradation over the life of a mission is acceptable as long as it is within predictable limits. Electrical power conversion systems with inherent redundancy, such as thermoelectric conversion systems, have been favored to date. Also, radioactive decay heat has been used to maintain temperatures in spacecraft at acceptable conditions for other components. This book describes how radioisotope systems work, the requirements and safety design considerations, the various systems that have been developed, and their operational history.

Are we alone in the universe? If not, where is everybody? An engaging exploration of one of the most important unsolved problems in science. Everything we know about how planets form and how life arises suggests that human civilization on Earth should not be unique. We ought to see abundant evidence of extraterrestrial activity-but we don't. Where is everybody? In this volume in the MIT Press Essential Knowledge series, science and technology writer Wade Roush examines one of the great unsolved problems in science: is there life, intelligent or otherwise, on other planets? This paradox (they're bound to be out there; but where are they?), first formulated by the famed physicist Enrico Fermi, has fueled decades of debate, speculation, and, lately, some actual science. Roush lays out the problem in its historical and modern-day context and summarizes the latest thinking among astronomers and astrobiologists. He describes the long history of speculation about aliens (we've been debating the idea for thousands of years); the emergence of SETI (the Search for Extraterrestrial Intelligence) as a scientific discipline in the 1960s, and scientists' use of radio and optical techniques to scan for signals; and developments in astrobiology (the study of how life might arise in non-Earth like environments) and exoplanet research (the discovery of planets outside our solar system). Finally, he discusses possible solutions to the Fermi Paradox and suggests way to refocus SETI work that might increase the chances of resolving the paradox-and finding extraterrestrials.

Affecting technological systems at a global-scale, space weather can disrupt high-frequency radio signals, satellite-based communications, navigational satellite positioning and timing signals, spacecraft operations, and electric power delivery with cascading socioeconomic effects resulting from these disruptions. Space weather can also present an increased health risk for astronauts, as well as aviation flight crews and passengers on transpolar flights. In 2019, the National Academies was approached by the National Aeronautics and Space Administration, the National Oceanic and Atmospheric Administration, and the National Science Foundation to organize a workshop that would examine the operational and research infrastructure that supports the space weather enterprise, including an analysis of existing and potential future measurement gaps and opportunities for future enhancements. This request was subsequently modified to include two workshops, the first ("Phase I") of which occurred in two parts on June 16-17 and September 9-11, 2020. The Phase II workshop occurred on April 11-14, 2022, with sessions on agency updates, research needs, data science, observational and modeling needs, and emerging architectures relevant to the space weather research community and with ties to operational needs. This publication summarizes the presentation and discussion of that workshop.

April 12, 2011 was the 50th Anniversary of Yuri Gagarin's pioneering journey into space. To commemorate this momentous achievement, Springer-Praxis has produced a mini-series of books that reveals how humanity's knowledge of flying, working and living in space has grown in the last half century.

The fifth and final volume in the miniseries focuses on The Twenty-First Century, in which the construction of the International Space Station, from the launch of its first element (the Russian Zarya control module) in 1998 to the end of the Shuttle-focused construction effort (with the Tranquility Node-3, the cupola and the Alpha Magnetic Spectrometer) in 2011. All the expeditions up to the 2011 anniversary of Gagarin are explored in detail, the make-up of crews, the shift from three-crew to two-crew, the effect of the STS-107 tragedy on the project and the eventual push to a six-person permanent occupancy. The final Hubble repair mission, STS-125, provides an opportunity not just to discuss the flight itself, but also to explore the mechanics and principles behind having rescue missions on standby and will spur a discussion of the changing focus of Shuttle operations in the wake of Columbia. The remarkable arrival of the Chinese Shenzhou on the scene and its whirlwind of achievements in such a short space of time is explored, as its potential for contributions in the future. Similarly, the arrival of the first space tourists with Dennis Tito in 2001 is considered and the future of such projects are discussed, including Virgin Galactic. The future in space is considered: ongoing Russian projects, Orion, the return to the Moon and on to Mars and this book closes with a snapshot of where humanity may be on the hundredth anniversary of Gagarin."

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).

Mars is ingrained in our culture, from David Bowie's extra-terrestrial spiders to H.G. Wells's The War of the Worlds. The red planet has inspired hundreds of scientists, authors and filmmakers - but why? What is it about this particular planet that makes it so intriguing?

Ancient mythologies defined Mars as a violent harbinger of war, and astrologers found meaning in the planet's dance through the sky. Stargazers puzzled over Mars's unfamiliar properties; some claimed to see canals criss-crossing its surface, while images from early spacecraft showed startling faced and pyramids carved out of rusty rock. Did Martians exist? If so, were they intelligent, civilised beings?

We now have a better understanding of Mars: its red hue, small moons, atmosphere (or lack of it), and mysterious past. Robots have trundled across the planet's surface, beaming back astonishing views of the alien landscape and seeking clues on how it has evolved. While little green Martians are now firmly the preserve of literature, evidence is growing that the now arid, frozen planet was once warmer, wetter, and possibly thronging with microbial life. Soon, we may set food on the planet. What challenges are involved, and how are we preparing for them? Is there a future for humanity on Mars?

In 4th Rock from the Sun, Nicky Jenner reviews Mars in its entirety, exploring its nature, attributes, potential as a human colony and impact on 3rd Rock-culture - everything you need to know about the Red Planet.

Adriana Ocampo grew up in Buenos Aires, Argentina, dreaming about exploring planets. She never doubted that all her dreams would come true someday. How did Adriana land a job with NASA, the U.S. space agency, while still in her teens? How did a robot parked on Mars make her fall in love with rocks and instantly decide to become a planetary geologist? Adriana's imagination and can-do attitude have led her to a life of science adventures. Adriana helped find the missing Crater of Doom, a hole blasted out of Earth by a killer space rock 65 million years ago, when the dinosaurs died out. Now she's searching the world for the stuff that came from that crater. Between rock digs she explores other planets through the electronic eyes of NASA's robotic spacecraft. How did an imaginative young girl with a dream of space exploration become a planetary geologist? Author Lorraine Jean Hopping makes the woman and her science come to life on every page, delighting readers of all ages.

A noted space expert explains the current revolution in spaceflight, where it leads, and why we need it. A new space race has begun. But the rivals in this case are not superpowers but competing entrepreneurs. These daring pioneers are creating a revolution in spaceflight that promises to transform the near future. Astronautical engineer Robert Zubrin spells out the potential of these new developments in an engrossing narrative that is visionary yet grounded by a deep understanding of the practical challenges. Fueled by the combined expertise of the old aerospace industry and the talents of Silicon Valley entrepreneurs, spaceflight is becoming cheaper. The new generation of space explorers has already achieved a major breakthrough by creating reusable rockets. Zubrin foresees more rapid innovation, including global travel from any point on Earth to another in an hour or less; orbital hotels; moon bases with incredible space observatories; human settlements on Mars, the asteroids, and the moons of the outer planets; and then, breaking all limits, pushing onward to the stars. Zubrin shows how projects that sound like science fiction can actually become reality. But beyond the how, he makes an even more compelling case for why we need to do this--to increase our knowledge of the universe, to make unforeseen discoveries on new frontiers, to harness the natural resources of other planets, to safeguard Earth from stray asteroids, to ensure the future of humanity by expanding beyond its home base, and to protect us from being catastrophically set against each other by the false belief that there isn't enough for all.

The 2011 National Research Council decadal survey on biological and physical sciences in space, Recapturing a Future for Space Exploration: Life and Physical Sciences Research for a New Era, was written during a critical period in the evolution of science in support of space exploration. The research agenda in space life and physical sciences had been significantly descoped during the programmatic adjustments of the Vision for Space Exploration in 2005, and this occurred in the same era as the International Space Station (ISS) assembly was nearing completion in 2011. Out of that period of change, Recapturing a Future for Space Exploration presented a cogent argument for the critical need for space life and physical sciences, both for enabling and expanding the exploration capabilities of NASA as well as for contributing unique science in many fields that can be enabled by access to the spaceflight environment. Since the 2011 publication of the decadal survey, NASA has seen tremendous change, including the retirement of the Space Shuttle Program and the maturation of the ISS. NASA formation of the Division of Space Life and Physical Sciences Research and Applications provided renewed focus on the research of the decadal survey. NASA has modestly regrown some of the budget of space life and physical sciences within the agency and engaged the U.S. science community outside NASA to join in this research. In addition, NASA has collaborated with the international space science community. This midterm assessment reviews NASA's progress since the 2011 decadal survey in order to evaluate the high-priority research identified in the decadal survey in light of future human Mars exploration. It makes recommendations on science priorities, specifically those priorities that best enable deep space exploration.

David Harvey is unquestionably the most influential, as well as the most cited, geographer of his generation. His reputation extends well beyond geography to sociology, planning, architecture, anthropology, literary studies and political science. This book brings together for the first time seminal articles published over three decades on the tensions between geographical knowledges and political power and on the capitalist production of space. Classic essays reprinted here include 'On the history and present condition of geography', 'The geography of capitalist accumulation' and 'The spatial fix: Hegel, von Thunen, and Marx'. Two new chapters represent the author's most recent thinking on cartographic identities and social movements. David Harvey's persistent challenge to the claims of ethical neutrality on behalf of science and geography runs like a thread throughout the book. He seeks to explain the geopolitics of capitalism and to ground spatial theory in social justice. In the process he engages with overlooked or misrepresented figures in the history of geography, placing them in the context of intellectual history. The presence here of Kant, Von Thunen, Humboldt, Lattimore, Leopold alongside Marx, Hegel, Heidegger, Darwin, Malthus, Foucault and many others shows the deep roots and significance of geographical thought. At the same time David Harvey's telling observations of current social, environmental, and political trends show just how vital that thought is to the understanding of the world as it is and as it might be.

The National Advisory Committee for Aeronautics--forerunner of today's NASA--emerged in 1915, when airplanes were curiosities made of wood and canvas and held together with yards of baling wire. At the time an unusual example of government intrusion (and foresight, given the importance of aviation to national military concerns), the committee oversaw the development of wind tunnels, metal fabrication, propeller design, and powerful new high-speed aircraft during the 1920s and '30s. In this richly illustrated account, acclaimed historian of aviation Roger E. Bilstein combines the story of NACA and NASA to provide a fresh look at the agencies, the problems they faced, and the hard work as well as inventive genius of the men and women who found the solutions.

NACA research during World War II led to critical advances in U.S. fighter and bomber design and, Bilstein explains, contributed to engineering standards for helicopters. After 1945 the agency's test pilots experimented with jet-powered aircraft, testing both human and technical limits in trying to break the so-called "sound barrier." In October 1958, when the launch of the Soviet "Sputnik" signaled the beginning of the space race, NACA formed the nucleus of the new National Aeronautics and Space Agency. The new agency's efforts to meet President Kennedy's challenge--safely landing a man on the Moon and returning him to Earth before the end of the 1960s--is one of the great adventure stories of all time. Bilstein goes on to describe NASA's recent planetary and extraplanetary exploration, as well as its less well-known research into the future of aeronautical design.

NASA's Earth Science Division (ESD) conducts a wide range of satellite and suborbital missions to observe Earth's land surface and interior, biosphere, atmosphere, cryosphere, and oceans as part of a program to improve understanding of Earth as an integrated system. Earth observations provide the foundation for critical scientific advances and environmental data products derived from these observations are used in resource management and for an extraordinary range of societal applications including weather forecasts, climate projections, sea level change, water management, disease early warning, agricultural production, and the response to natural disasters. As the complexity of societal infrastructure and its vulnerability to environmental disruption increases, the demands for deeper scientific insights and more actionable information continue to rise. To serve these demands, NASA's ESD is challenged with optimizing the partitioning of its finite resources among measurements intended for exploring new science frontiers, carefully characterizing long-term changes in the Earth system, and supporting ongoing societal applications. This challenge is most acute in the decisions the Division makes between supporting measurement continuity of data streams that are critical components of Earth science research programs and the development of new measurement capabilities. This report seeks to establish a more quantitative understanding of the need for measurement continuity and the consequences of measurement gaps. Continuity of NASA's Earth's Observations presents a framework to assist NASA's ESD in their determinations of when a measurement or dataset should be collected for durations longer than the typical lifetimes of single satellite missions.

The National Research Council (NRC) has been conducting decadal surveys in the Earth and space sciences since 1964, and released the latest five surveys in the past 5 years, four of which were only completed in the past 3 years. Lessons Learned in Decadal Planning in Space Science is the summary of a workshop held in response to unforseen challenges that arose in the implementation of the recommendations of the decadal surveys. This report takes a closer look at the decadal survey process and how to improve this essential tool for strategic planning in the Earth and space sciences. Workshop moderators, panelists, and participants lifted up the hood on the decadal survey process and scrutinized every element of the decadal surveys to determine what lessons can be gleaned from recent experiences and applied to the design and execution of future decadal surveys.
