Radio spectrum for commanding and recording from our satellites is a shared resource with subtle hurdles. We walk the path originally paved by AMSATs to discuss the steps and licensing needed to set up and operate both a command uplink and a data download station and network. Find out how playing nicely with others maximizes your ability to get your data down.

The NASA Dawn mission, launched in 2007, aimed to visit two of the most massive protoplanets of the main asteroid belt: Vesta and Ceres. The aim was to further our understanding of the earliest days of the Solar System, and compare the two bodies to better understand their formation and evolution. This book summarises state-of-the-art results from the mission, and discusses the implications for our understanding not only of the asteroid belt but the entire Solar System. It comprises of three parts: Part 1 provides an overview of the main belt asteroids and provides an introduction to the Dawn mission; Part 2 presents key findings from the mission; and Part 3 discusses how these findings provide insights into the formation and evolution of the Solar System. This is a definitive reference for academic researchers and professionals of planetary science, asteroid science and space exploration.

'Brilliant. You won't find a clearer, more engaging guide to what we know (or would like to know) about the universe and how it is put together' Bill Bryson Celebrated physicist and global bestselling author Paul Davies tells the story of the universe in thirty cosmological conundrums In the constellation of Eridanus there lurks a cosmic mystery. It's as if something has taken a huge bite out of the universe, leaving a super-void. What could be the culprit? A super massive black hole? Another, bigger universe? Or an expanding vacuum bubble, destined to envelop and annihilate everything in existence? Scientists now understand the history of our universe better than the history of our own planet, but they continue to uncover startling new riddles-the hole in the universe being just one. In this electrifying book, award-winning physicist Paul Davies walks us through the puzzles and paradoxes that have preoccupied cosmologists from ancient Greece to the present day. Laying bare the audacious research that has led us to mind-bending solutions, Davies reveals how we might begin to approach the greatest outstanding enigmas of all.

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.

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). Originally published in 1995. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

In contrast to the close cooperation practiced among European states, space relations among Asian states have become increasingly tense. If current trends continue, the Asian civilian space competition could become a military race. To better understand these emerging dynamics, James Clay Moltz conducts the first in-depth policy analysis of Asia's fourteen leading space programs, concentrating especially on developments in China, Japan, India, and South Korea. Moltz isolates the domestic motivations driving Asia's space actors, revisiting critical events such as China's 2007 antisatellite weapons test and manned flights, Japan's successful Kaguya lunar mission and Kibo module for the International Space Station (ISS), India's Chandrayaan lunar mission, and South Korea's astronaut visit to the ISS, along with plans to establish independent space-launch capability. He investigates these nations' divergent space goals and their tendency to focus on national solutions and self-reliance rather than regionwide cooperation and multilateral initiatives. He concludes with recommendations for improved intra-Asian space cooperation and regional conflict prevention. Moltz also considers America's efforts to engage Asia's space programs in joint activities and the prospects for future U.S. space leadership. He extends his analysis to the relationship between space programs and economic development in Australia, Indonesia, Malaysia, North Korea, Pakistan, the Philippines, Singapore, Taiwan, Thailand, and Vietnam, making this a key text for international relations and Asian studies scholars.

This is a major new work on International Space Law by an author who has perhaps contributed more than any other scholar to its development. In it he examines the whole of the regime of international law and space law including the role of the United Nations, the legal status of outer space, astronauts and out of space objects, the military use of outer space, the commercial uses of outer space and in particular the emerging law relating to satellites and telecommunications, including the increasingly vexed problems of international responsibility and liability for national activities in space. A number of the chapters in this book have previously been published as essays in law journals and as chapters of books but this is the first time that all these major pieces appear together and the opportunity has been taken to revise and update where appropriate.

Radio telescopes have transformed our understanding of the Universe. Pulsars, quasars, Big Bang cosmology: all are discoveries of the new science of radio astronomy. Here, Francis Graham-Smith describes the birth, development, and maturity of radio astronomy, from the first discovery of cosmic radio waves to its present role as a major part of modern astronomy. Radio is part of the electromagnetic spectrum, covering infra-red, visible light, ultraviolet, X-rays, and gamma-rays, and Graham-Smith explains why it is that radio waves give us a unique view of the Universe. Tracing the development of radio telescopes he shows how each new idea in observing techniques has led to new discoveries, and looks at the ways in which radio waves are generated in the various cosmic sources, relating this to the radio world of mobile phones, radio and television channels, wireless computer connections, and remote car locks. Today a new generation of radio telescopes promises to extend our understanding of the Universe into further, as yet unknown, fields. Huge new radio telescopes are being built, such as the Atacama Large Millimetre Array (ALMA), Low Frequency Array for Radioastronomy (LOFAR), and the Square Kilometre Array (SKA). Radio telescopes on spacecraft such as the Cosmic Microwave Explorer (COBE) and Planck are tracing in minute detail the faint but universal radio signal from the expanding early Universe. Graham-Smith shares the excitement of discovering the wonders of the radio universe, and the possibilities promised by the new age of giant radio telescopes.

The efforts of the United States to develop defences against ballistic missiles (the Strategic Defense Initiative) is one of the most hotly debated topics of our time. This authoritative book contributes to the debate by presenting th searching and wide-ranging views of twenty-six international experts on the technical, legal, political, and military aspects of space weapons. They address such questions as: What are the technological promises and problems of strategic defence? What effects will SDI have on the arms race or on deterring nuclear war? How do China, India, and Japan perceive SDI? What can be done to guard international stability? These papers, which express every range of opinion on SDI, from an unqualified approval to total scepticism, are prefaced by an overview by the editor of the volume.

Few federal agencies have more extensive ties to the private sector than NASA. NASA's relationships with its many aerospace industry suppliers of rocket engines, computers, electronics, gauges, valves, O-rings, and other materials have often been described as "partnerships." These have produced a few memorable catastrophes, but mostly technical achievements of the highest order. Until now, no one has written extensively about them.

In "NASA and the Space Industry, " Joan Lisa Bromberg explores how NASA's relationship with the private sector developed and how it works. She outlines the various kinds of expertise public and private sectors brought to the tasks NASA took on, describing how this division of labor changed over time. She explains why NASA sometimes encouraged and sometimes thwarted the privatization of space projects and describes the agency's role in the rise of such new space industries as launch vehicles and communications satellites.

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.

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.
