For the first time the inside story of Russia's marketing of their space program to the West is chronicled by one who was there. The colourful tales are told, warts and all. How the door to Russia's long hidden space pro-gram was opened during the era of Soviet perestroika, the political struggle on the signing of the first contract between the Russians and NASA, the push to change space station Freedom into a co-operative venture, the willingness of the Russians to use free markets against the wishes of NASA and how the Russian space station Mir became a commercial platform, are all told in a relaxed and engaging style by the author, who is the only American ever to work within the Russian space program. The book chronicles the author's 14 year journey to use Russian assets to strengthen the American space program. Included is the behind-the-scenes of signing Dennis Tito, working with entertainment icons like James Cameron and Mark Burnett and the electrifying ride that was MirCorp. The book discusses the boycott organised by NASA to prevent MirCorp's success and the drama behind the world's only commercial manned expedition that sent two men to the Mirspace station for over two months, with no government funding. It is a tale of strong characters. Readers are given a front-row seat on the decade-long clash between the Russian chief Yuri Semenov and NASA's Dan Goldin, a paradoxical battle that saw the Russians embracing American open markets and NASA clinging to the Cold War model for space exploration.

The Star of Bethlehem (Paperback): Mark Kidger The Star of Bethlehem (Paperback)
Mark Kidger
R1,957 Discovery Miles 19 570 Ships in 10 - 15 working days

Two thousand years ago, according to the Bible, a star rose low in the east and stopped high above Bethlehem. Was it a miracle, a sign from God to herald the birth of Christ? Was there a star at all, or was it simply added to the Bible to fulfill the Old Testament prophecy concerning the birth of the Messiah? Or was the Star of Bethlehem an actual astronomical event? For hundreds of years, astronomers as prominent as Johannes Kepler have sought an answer to this last baffling question. In The Star of Bethlehem, Mark Kidger brings all the tools of modern science, years of historical research, and an infectious spirit of inquiry to bear on the mystery. He sifts through an astonishing variety of ideas, evidence, and information--including Babylonian sky charts, medieval paintings, data from space probes, and even calculations about the speed of a camel--to present a graceful, original, and scientifically compelling account of what it may have been that illuminated the night skies two millennia ago. Kidger begins with the stories of early Christians, comparing Matthew's tale of the Star and the three Magi who followed it to Bethlehem with lesser-known accounts excluded from the Bible. Crucially, Kidger follows the latest biblical scholarship in placing Christ's birth between 7 and 5 B.C., which leads him to reject various phenomena that other scientists have proposed as the Star. In clear, colorful prose, he then leads us through the arguments for and against the remaining astronomical candidates. Could the Star have been Venus? What about a meteor or a rare type of meteor shower? Could it have been Halley's Comet, as featured in Giotto's famous painting of the Nativity? Or, as Kidger suspects, was the Star a combination of events--a nova recorded in ancient Chinese and Korean manuscripts preceded by a series of other events, including an unusual triple conjunction of planets? Originally published in 1999. 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.

R1,200 Discovery Miles 12 000 Ships in 12 - 17 working days

Jonathan Ward takes the reader deep into the facilities at Kennedy Space Center to describe NASA's first computer systems used for spacecraft and rocket checkout and explain how tests and launches proceeded. Descriptions of early operations include a harrowing account of the heroic efforts of pad workers during the Apollo 1 fire. A companion to the author's book Countdown to a Moon Launch: Preparing Apollo for Its Historic Journey, this explores every facet of the facilities that served as the base for the Apollo/Saturn missions. Hundreds of illustrations complement the firsthand accounts of more than 70 Apollo program managers and engineers. The era of the Apollo/Saturn missions was perhaps the most exciting period in American space exploration history. Cape Canaveral and Kennedy Space Center were buzzing with activity. Thousands of workers came to town to build the facilities and launch the missions needed to put an American on the Moon before the end of the decade. Work at KSC involved much more than just launching rockets. It was a place like none other on Earth. Technicians performed intricate operations, and hazards abounded everywhere, including lightning, fire, highly-toxic fuels, snakes, heat, explosives, LOX spills, and even plutonium. The reward for months of 7-day workweeks under intense pressure was witnessing a Saturn V at liftoff. For anyone who ever wished they had worked at Kennedy Space Center during the Apollo era, this book is the next best thing. The only thing missing is the smell of rocket fuel in the morning.

This is a critical time for the space program, and for all of us. Even the significant steps that we have taken since the dawn of the space age in 1957, including orbital flight, the Moon landings, and orbiting space stations, will in retrospect seem to be tiny steps compared to what lies ahead. Migrating into space will challenge us beyond anything we have previously accomplished, and we are destined to face adventures that are both fantastically breathtaking and supremely dangerous. "Beyond Earth" is for everyone interested in humankind's next great adventure - the human settlement of the Solar System. A unique collection of world-class scholars, scientists, engineers, managers, astronauts, artists, authors, and professors examine the key questions of our unique circumstance at the dawn of a new era in space exploration and development: Why does space matter to us? What can we use it for? How can we get there efficiently? What will ordinary life be like in space? What will our homes be like on the Moon? On Mars? In orbit? Will we play? Will we love? The book does not stop with questions.;It goes beyond the dramatic, the superficial, and the overly technical to the prescriptive, literally laying the brick and mortar for our future space faring civilisation. Contributing authors come from both hard and soft sciences; include education and the arts; and ask children, who will be the future space dwellers, for their visions. They document needed research. There are three underlying assumptions driving this book: First, that the human urge for flight, exploration and survival, plus its curiosity about the universe, are deeply embedded in our genes and in our minds; Second, that even if these urges were ignored, the continual improvement of the quality of life for the human race on earth, and perhaps even its ultimate survival, hinge on the successes of human exploration and habitation of space; and, Third that our generation can use the opportunity presented by outwards expansion to design a rewarding and exciting future of collaboration to capitalise on the lessons learned from human history on Earth.

With plans to launch hotels into orbit and experiments in suspending and reanimating life for ultra-long-distance travel, private companies and entrepreneurs have outpaced NASA which is bogged down by terrestrial concerns as the leaders in the new space race. With accessible prose and relentless curiosity, Chris Impey reports on China s plan to launch its own space station by 2020, proves that humans could survive on Mars, and unveils cutting-edge innovations such as the space elevators poised to replace rockets at a fraction of the cost. Setting mankind s urge toward exploration in the context of all human history and space travel thus far, he shows that the present-day scientists mapping billions of Earth-like exo-planets are the descendants of the first humans to venture out of Africa. We must forge ahead, argues Beyond, because exploration is in our DNA."

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."

Our nearest celestial neighbour, the Moon, has always been the most conspicuous feature in our night sky. It has compelled observers since the dawn of humankind, and all have tried to make sense in their own ways of the puzzles it poses and the questions it raises. It provided our ancient ancestors with one of the earliest means of keeping and measuring time, and many early religions had cults that worshipped the Moon. It regulates the tides and has been held accountable for numerous human conditions, most notably madness and psychological disorders. Drawing on many years of practical observation, Bill Leatherbarrow provides an illuminating insight into the history and evolution of this enthralling astronomical body. He describes how and why the study of the Moon has evolved, particularly in the age of the telescope, and offers an overview of developments in lunar science since the advent of the space age. Leatherbarrow also provides practical advice on how to make your own observations of the Moon. Extensively illustrated with images of the lunar surface, The Moon is an accessible introduction that will appeal to both amateur and professional astronomers and all those fascinated by Earth's natural satellite.

If you have ever wondered about space travel, now you have the opportunity to understand it more fully than ever before. Traveling into space and even emigrating to nearby worlds may soon become part of the human experience. Scientists, engineers, and investors are working hard to make space tourism and colonization a reality. As astronauts can attest, extraterrestrial travel is incomparably thrilling. To make the most of the experience requires serious physical and mental adaptations in virtually every aspect of life, from eating to intimacy. Everyone who goes into space sees Earth and life on it from a profoundly different perspective than they had before liftoff. Astronomer and former NASA/ASEE scientist Neil F. Comins has written the go-to book for anyone interested in space exploration. He describes the wonders that travelers will encounter-weightlessness, unparalleled views of Earth and the cosmos, and the opportunity to walk on another world-as well as the dangers: radiation, projectiles, unbreathable atmospheres, and potential equipment failures. He also provides insights into specific trips to destinations including suborbital flights, space stations, the Moon, asteroids, comets, and Mars-the top candidate for colonization. Although many challenges are technical, Comins outlines them in clear language for all readers. He synthesizes key issues and cutting-edge research in astronomy, physics, biology, psychology, and sociology to create a complete manual for the ultimate voyage.

R1,096 Discovery Miles 10 960 Ships in 12 - 17 working days

"Have you ever seen a total solar eclipse?" If the question caused you to search your memory, the correct answer would have been "no." A common response is: "Yes-I saw one, it was about 90% partial eclipse where I lived." A 90% partial eclipse is indeed a remarkable phenomenon, but true totality leaves all else in the shade, in all senses of the phrase. Ask the question of anyone who has experienced the full sensation of being obliterated by the moon's shadow, and they will reply "yes"-without hesitation-and continue with a monologue describing the overwhelming experiences and unique phenomena that ensued. On 21 August 2017 millions of people across the United States witnessed "The Great American Eclipse" of the Sun. The moment it was over, people around the world were asking questions: what caused the weird shadows and colors in the build up to totality? Were those ephemeral bands of shadows gliding across the ground in the seconds before totality real or an optical illusion? Why this, what that, but above all: where and when can I see a total solar eclipse again? Eclipses: What Everyone Needs to Know helps explain the profound differences between a 99.99% partial eclipse and true totality, and inform readers how to experience this most beautiful natural phenomenon successfully. It covers eclipses of sun, moon, and other astronomical objects, and their applications in science, as well as their role in history, literature, and myth. It describes the phenomena to expect at a solar eclipse and the best ways to record them-by camera, video, or by simple handmade experiments. The book covers the timetable of upcoming eclipses, where the best locations will be to see them, and the opportunities for using them as vehicles for inspiration and education. As a veteran of seven total solar eclipses, physicist Frank Close is an expert both on the theory and practice of eclipses. Eclipses: What Everyone Needs to Know is a popular source of information on the physics of eclipses.

Astronomy with a Budget Telescope, 2nd Edition is a complete introduction to buying and using a low-cost amateur astronomical telescope. It provides essential hints and tips about what to look for when buying on a budget - the best are now excellent value, but they all lack an astronomer's advice about setting them up and using them. Astronomy with a Budget Telescope was first published in 2003, since then technology has moved on substantially. The main factors are first the availability of fairly inexpensive computer-controlled "go-to" telescopes which after setting up can automatically locate any celestial objects with reasonable accuracy. Second, digital cameras have now almost completely displaced "wet" film cameras, and some of them are particularly well-suited to astronomical use. Third, prices are down and quality is up! This new edition is revised and extended to include using a low-cost "go-to" telescope - there are various pitfalls to be avoided - and how this class of instrument can make amateur astronomy more accessible to those with limited time at their disposal. It also discusses the new breed of mid-range digital cameras that include powerful on-board processing and image enhancement software that used to be available only to people with advanced astronomical CCD cameras. Finally, there are detailed reviews and test reports on some of the budget telescopes that are available on Main Street and by mail order.

A few hundred years into the future, a wave of space colonization follows a disastrous earlier attempt to inhabit nearby extrasolar planets. It is guided by a new computational method based on massive data-driven socio-cultural and socio-epidemiological modeling and using novel biological computers, fed with data on Earth's history of successes and failures. Yet, in the newly settled Simpac system, some unexpected and worrying anomalies begin cropping up, making an urgent expedition to the system necessary: is it the underlying data, the computations, or is some unknown entity tampering with the space colonization program? A race against time ensues as the lives of four strangers begin to converge. While grounded in the social systems aspect, the author posits that the future is likely to be characterized by more biology-based tools than most contemporary science fiction - which most often relies entirely on non-biological hardware in terms of advanced technologies - predicts. The result is an entertaining and skillful blend of thriller and SF, complemented by a nontechnical appendix describing the underlying science.

Is Pluto a Planet? - A Historical Journey through the Solar System (Paperback, Revised edition): David A. Weintraub Is Pluto a Planet? - A Historical Journey through the Solar System (Paperback, Revised edition)
David A. Weintraub
R858 Discovery Miles 8 580 Ships in 10 - 15 working days

A Note from the Author: On August 24, 2006, at the 26th General Assembly of the International Astronomical Union (IAU) in Prague, by a majority vote of only the 424 members present, the IAU (an organization of over 10,000 members) passed a resolution defining planet in such a way as to exclude Pluto and established a new class of objects in the solar system to be called "dwarf planets," which was deliberately designed to include Pluto.

With the discovery of Eris (2003 UB313)--an outer solar system object thought to be both slightly larger than Pluto and twice as far from the Sun--astronomers have again been thrown into an age-old debate about what is and what is not a planet. One of many sizeable hunks of rock and ice in the Kuiper Belt, Eris has resisted easy classification and inspired much controversy over the definition of planethood. But, Pluto itself has been subject to controversy since its discovery in 1930, and questions over its status linger. Is it a planet? What exactly is a planet?

"Is Pluto a Planet?" tells the story of how the meaning of the word "planet" has changed from antiquity to the present day, as new objects in our solar system have been discovered. In lively, thoroughly accessible prose, David Weintraub provides the historical, philosophical, and astronomical background that allows us to decide for ourselves whether Pluto is indeed a planet.

The number of possible planets has ranged widely over the centuries, from five to seventeen. This book makes sense of it all--from the ancient Greeks' observation that some stars wander while others don't; to Copernicus, who made Earth a planet but rejected the Sun and the Moon; to the discoveries of comets, Uranus, Ceres, the asteroid belt, Neptune, Pluto, centaurs, the Kuiper Belt and Eris, and extrasolar planets.

Weaving the history of our thinking about planets and cosmology into a single, remarkable story, "Is Pluto a Planet?" is for all those who seek a fuller understanding of the science surrounding both Pluto and the provocative recent discoveries in our outer solar system.
