Through that observation, astronomers could calculate the size of the solar system—but only if they could compile data from many different points of the globe, all recorded during the short period of the transit. Overcoming incredible odds and political strife, astronomers from Britain, France, Russia, Germany, Sweden, and the American colonies set up observatories in remote corners of the world, only to have their efforts thwarted by unpredictable weather and warring armies. Fortunately, transits of Venus occur in pairs: eight years later, the scientists would have another opportunity to succeed.   Chasing Venus brings to life the personalities of the eighteenth-century astronomers who embarked upon this complex and essential scientific venture, painting a vivid portrait of the collaborations, the rivalries, and the volatile international politics that hindered them at every turn. In the end, what they accomplished would change our conception of the universe and would forever alter the nature of scientific research.

    Seventy-three seconds after launch, the fiery breach of a solid motor joint caused a rupture of the propellant tanks, and a stunned nation watched as flames engulfed the craft, killing all seven crew members on board. It was Hugh Harris, “the voice of launch control,” whom audiences across the country heard counting down to lift-off on that fateful day.With over fifty years of experience with NASA’s missions, Harris presents the story of the Challenger tragedy as only an insider can. With by-the-second accounts of the spacecraft’s launch and a comprehensive overview of the ensuing investigation, Harris gives readers a behind-the-scenes look at the devastating accident that grounded the shuttle fleet for over two years. This book tells the whole story of the Challenger’s tragic legacy.

    In the 1960s most computers filled an entire room, but the spacecraft's computer was required to be compact and low power. Although people today find it difficult to accept that it was possible to control a spacecraft using such a 'primitive' computer, it nevertheless had capabilities that are advanced even by today's standards.This is the first book to fully describe the Apollo guidance computer's architecture, instruction format and programs used by the astronauts. As a comprehensive account, it will span the disciplines of computer science, electrical and aerospace engineering. However, it will also be accessible to the 'space enthusiast'. In short, the intention is for this to be the definitive account of the Apollo guidance computer.Frank O'Brien's interest in the Apollo program began as a serious amateur historian. About 12 years ago, he began performing research and writing essays for the Apollo Lunar Surface Journal, and the Apollo Flight Journal. Much of this work centered on his primary interests, the Apollo Guidance Computer (AGC) and the Lunar Module. These Journals are generally considered the canonical online reference on the flights to the Moon. He was then asked to assist the curatorial staff in the creation of the Cradle of Aviation Museum, on Long Island, New York, where he helped prepare the Lunar Module simulator, a LM procedure trainer and an Apollo space suit for display. He regularly lectures on the Apollo computer and related topics to diverse groups, from NASA's computer engineering conferences, the IEEE/ACM, computer festivals and university student groups.

    Jo Marchant's book can begin to heal it. For at least 20,000 years, we have led not just an earthly existence but a cosmic one. Celestial cycles drove every aspect of our daily lives. Our innate relationship with the stars shaped who we are--our art, religious beliefs, social status, scientific advances, and even our biology. But over the last few centuries we have separated ourselves from the universe that surrounds us. It's a disconnect with a dire cost.Our relationship to the stars and planets has moved from one of awe, wonder and superstition to one where technology is king--the cosmos is now explored through data on our screens, not by the naked eye observing the natural world. Indeed, in most countries modern light pollution obscures much of the night sky from view. Jo Marchant's spellbinding parade of the ways different cultures celebrated the majesty and mysteries of the night sky is a journey to the most awe inspiring view you can ever see--looking up on a clear dark night. That experience and the thoughts it has engendered have radically shaped human civilization across millennia. The cosmos is the source of our greatest creativity in art, in science, in life.To show us how, Jo Marchant takes us to the Hall of the Bulls in the caves at Lascaux in France, and to the summer solstice at a 5,000-year-old tomb at New Grange in England. We discover Chumash cosmology and visit medieval monks grappling with the nature of time and Tahitian sailors navigating by the stars. We discover how light reveals the chemical composition of the sun, and we are with Einstein as he works out that space and time are one and the same. A four-billion-year-old meteor inspires a search for extraterrestrial life. The cosmically liberating, summary revelation is that star-gazing made us human.

    A favorite of Tesla and SpaceX founder Elon Musk, listeners will want to tune into this "really good book on rocket[s]," available for the first time in audio. Ignition! is the story of the search for a rocket propellant which could be trusted to take man into space. This search was a hazardous enterprise carried out by rival labs who worked against the known laws of nature, with no guarantee of success or safety. Acclaimed scientist and sci-fi author John Drury Clark writes with irreverent and eyewitness immediacy about the development of the explosive fuels strong enough to negate the relentless restraints of gravity. The resulting volume is as much a memoir as a work of history, sharing a behind-the-scenes view of an enterprise that eventually took men to the moon, missiles to the planets, and satellites to outer space. A classic work in the history of science, listeners will want to get their hands on this influential classic, available for the first time in decades.

    Then, in 2005, astronomer Mike Brown made the discovery of a lifetime: a tenth planet, Eris, slightly bigger than Pluto. But instead of its resulting in one more planet being added to our solar system, Brown’s find ignited a firestorm of controversy that riled the usually sedate world of astronomy and launched him into the public eye. The debate culminated in the demotion of Pluto from real planet to the newly coined category of “dwarf” planet. Suddenly Brown was receiving hate mail from schoolchildren and being bombarded by TV reporters—all because of the discovery he had spent years searching for and a lifetime dreaming about.Filled with both humor and drama, How I Killed Pluto and Why It Had It Coming is Mike Brown’s engaging first-person account of the most tumultuous year in modern astronomy—which he inadvertently caused. As it guides readers through important scientific concepts and inspires us to think more deeply about our place in the cosmos, it is also an entertaining and enlightening personal story: While Brown sought to expand our understanding of the vast nature of space, his own life was changed in the most immediate, human ways by love, birth, and death. A heartfelt and personal perspective on the demotion of everyone’s favorite farflung planet, How I Killed Pluto and Why It Had It Coming is the book for anyone, young or old, who has ever dreamed of exploring the universe—and who among us hasn’t?

    

    Over the course of the next three-and-a-half years, twelve lunar explorers, including Alan Shepard and Gene Cernan, touched down on the moon's surface. Author and engineer Suzanne Slade reveals how the Apollo missions (1969-1972) built upon one another and led to important discoveries about our nearest neighbor in space. Back matter includes an afterword by Alan Bean (1932-2018), the fourth person to walk on the moon.

    When NASA needed to land Curiosity—a 2,000-pound, $2.5 billion rover—on the surface of Mars, 140 million miles away, they turned to JPL. Steltzner’s team couldn’t test their kooky solution, the Sky Crane. They were on an unmissable deadline, and the world would be watching when they succeeded—or failed. At the helm of this effort was an unlikely rocket scientist and accidental leader, Adam Steltzner. After barely graduating from high school, he followed his curiosity to the local community college to find out why the stars moved. Soon he discovered an astonishing gift for math and physics. After getting his Ph.D. he ensconced himself within JPL, NASA’s decidedly unbureaucratic cousin, where success in a mission is the only metric that matters.  The Right Kind of Crazy is a first-person account of innovation that is relevant to any­one working in science, art, or technology. For instance, Steltzner describes: ·How his team learned to switch from fear-based to curiosity-based decision making·How to escape “The Dark Room”—the creative block caused by fear, uncertainty, and the lack of a clear path forward·How to tell when we’re too in love with our own ideas to be objective about them—and, conversely, when to fight for them·How to foster mutual respect within teams while still bashing bad ideas The Right Kind of Crazy is a book for anyone who wants to channel their craziness into creativity, balance discord and harmony, and find a signal in a flood of noise.

    It was to be a routine mission, the 4th of seven trips to Mir that NASA astronauts would take as dress rehearsals for the two countries' partnership in a new Intern'l Space Station they were building back on Earth. But there'd been bad omens: a Moscow psychic who predicted a mysterious disaster; a Russian doctor who warned that the crew was psychologically incompatible. Within two weeks the omens were borne out, as the three were suddenly forced to fight the worst fire in space history. This was only the beginning of what became the most dangerous mission in the 36-year history of manned space travel--a 6-month misadventure that would climax in the most harrowing accident faced in space since Apollo 13. In Dragonfly, bestselling author Burrough tells the story of how a joint Russian-American crew narrowly survived almost every trauma imaginable: fire, power blackouts, chemical leaks, docking failures, nail-biting spacewalks & constant mechanical breakdowns, all climaxing in a dramatic midspace collision that left all on board scrambling for their lives. Based on hundreds of hours of interviews with the cosmonauts, astronauts, ground controllers, psychologists & scientists involved, Dragonfly is the saga of a mission as fraught with political & bureaucratic intrigues as any DC potboiler. Using never-before-released internal NASA memoranda, flight logs & debriefings, Burrough portrays a US space program in which many astronauts refuse to raise safety concerns for fear they'll be frozen out of future missions. It offers an unprecedented look inside the rattletrap Russian space program, where the desperate thirst for hard currency leads to safety shortcuts as exhausted, puppetlike cosmonauts endure inhuman pressures from their unfeeling, all-powerful masters on the ground. In Dragonfly, the American astronauts who journeyed to Mir speak out about the failings of the program, from the rigors of training at Russia's Star City military base to the slapdash experiments they were required to perform. Yet thru it all the men & women of the two space programs persevered, forging friendships that will serve them well as the two countries prepare for the 1st launches of the Intern'l Space Station in late 1998. Theirs is a story of a triumph over adversity, destined to be one of the most enduring & widely celebrated adventure stories of our time.

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.

    To celebrate, this book covers his amazing writing career, spanning over four decades and more than 400

    South, by historian Hunter Stewart, chronicles the competition between two fierce rivals - Robert F. Scott and Roald Amundsen - to secure their place in history as the first man to lead an expedition to the most uninhabitable place on earth. South dramatically tells the story of the quest that is marked by heartbreak, greed, ego, and bravery - not only by Scott and Amundsen but by the courageous crews and financial backers who supported them. The journey to reach the South Pole was truly, as it was later called, "The Heroic Age of Arctic Exploration."

    Filled with data about the Earth, Moon, the planets, the stars, our Galaxy, and the myriad galaxies in deep space, it also reveals the latest scientific discoveries about black holes, quasars, and the origins of the Universe. Written by a premier astronomy expert, this book begins with a discussion of the Sun, from sunspots to solar eclipses. It then features over 100 tables on characteristics of the Moon, and the names, positions, sizes, and other key descriptors of all the planets and their satellites. The book tabulates solar and lunar eclipse, comets, close-approach asteroids, and significant meteor showers dates. Twenty-four maps show the surface features of the planets and their moons. The author then looks to the stars, their distances and movements, and their detailed classification and evolution. Forty-eight star charts cover both northern and southern hemispheres, enabling you to track down and name the main stars in all the constellations. The maps are supported by detailed tables of the names, positions, magnitudes, and spectra of the main stars in each constellation, along with key data on galaxies, nebulae, and clusters. There is a useful catalogue of the world's great telescopes and observatories, a history of astronomy and of space research, and biographies of 250 astronomers who have been most influential in developing the current understanding of the subject.

    All that mattered to Neil as he searched for a safe spot to land was that boulders littered the surface below. "Thirty seconds," called mission control. In truth, the flight controllers were now no more than spectators, just like everybody else. No more needed to be said.It was down to Armstrong.'Simultaneously connected and separated by television, millions of people around the world held their breath as a human being looked back at them from the surface of the Moon. Yet who were these men capable of such an achievement? How did the passionate Buzz Aldrin, inscrutable Michael Collins and enigmatic Neil Armstrong learn to depend on one another as they endured the most intense period of their lives?From the personal tragedies and triumphs they encountered along the way to the terrifying climax of a mission that redefined humanity, Moonshot - now also a major TV factual-drama - draws on interviews with many of the leading participants and hundreds of hours of archive material to tell the compelling true story of an event that captured the imagination of generations, then and now.
