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.

    This minute-by-minute account of the only manned NASA mission to have malfunctioned outside Earth's orbit describes the entire episode.

    Growing up in a working-class Long Island family, Massimino catapulted himself to Columbia and then MIT, only to flunk his qualifying exams and be rejected twice by NASA before making it to the final round of astronaut selection—where he was told his poor eyesight meant he’d never make the cut. But even that couldn’t stop him from finally earning his wings, making the jump to training in T-38 Air Force jets and preparing his body—and soul—for the journey to the cosmos.Taking us through the surreal wonder and beauty of his first spacewalk, the tragedy of losing friends in the Columbia shuttle accident, and the development of his enduring love for the Hubble telescope—which he’d be tasked with saving on his final mission— Massimino has written an ode to never giving up and the power of teamwork to make anything possible. Spaceman invites us into a rare, wonderful world where the nerdiest science meets the most thrilling adventure, and pulls back a curtain on just what having “the right stuff” really means.

    space program. In this meticulously researched and vividly written life, Michael J. Neufeld gives us a man of profound moral complexities, glorified as a visionary and vilified as a war criminal, a man whose brilliance and charisma were coupled with an enormous and, some would say, blinding ambition.As one of the leading developers of rocket technology for the German army, von Braun yielded to pressure to join the Nazi Party in 1937 and reluctantly became an SS officer in 1940. During the war, he supervised work on the V-2s, which were assembled by starving slave laborers in a secret underground plant and then fired against London and Antwerp. Thousands of prisoners died—a fact he well knew and kept silent about for as long as possible.When the Allies overran Germany, von Braun and his team surrendered to the Americans. The U.S. Army immediately recognized his skills and brought him and his colleagues to America to work on the development of guided missiles, in a covert operation that became known as Project Paperclip. He helped launch the first American satellite in 1958 and headed NASA’s launch-vehicle development for the Apollo Moon landing.Handsome and likable, von Braun dedicated himself to selling the American public on interplanetary travel and became a household name in the 1950s, appearing on Disney TV shows and writing for popular magazines. But he never fully escaped his past, and in later years he faced increasing questions as his wartime actions slowly came to light.Based on new sources, Von Braun is a brilliantly nuanced portrait of a man caught between morality and progress, between his dreams of the heavens and the earthbound realities of his life.

    Less than 20 years after its founding, it boasts the largest constellation of commercial satellites in orbit, has pioneered reusable rockets, and in 2020 became the first private company to launch human beings into orbit. Half a century after the space race it is private companies, led by SpaceX, standing alongside NASA pushing forward into the cosmos, and laying the foundation for our exploration of other worlds.But before it became one of the most powerful players in the aerospace industry, SpaceX was a fledgling startup, scrambling to develop a single workable rocket before the money ran dry. The engineering challenge was immense; numerous other private companies had failed similar attempts. And even if SpaceX succeeded, they would then have to compete for government contracts with titans such as Lockheed Martin and Boeing, who had tens of thousands of employees and tens of billions of dollars in annual revenue. SpaceX had fewer than 200 employees and the relative pittance of $100 million in the bank.In Liftoff, Eric Berger, senior space editor at Ars Technica, takes readers inside the wild early days that made SpaceX. Focusing on the company’s first four launches of the Falcon 1 rocket, he charts the bumpy journey from scrappy underdog to aerospace pioneer. We travel from company headquarters in El Segundo, to the isolated Texas ranchland where they performed engine tests, to Kwajalein, the tiny atoll in the Pacific where SpaceX launched the Falcon 1. Berger has reported on SpaceX for more than a decade, enjoying unparalleled journalistic access to the company’s inner workings. Liftoff is the culmination of these efforts, drawing upon exclusive interviews with dozens of former and current engineers, designers, mechanics, and executives, including Elon Musk. The enigmatic Musk, who founded the company with the dream of one day settling Mars, is the fuel that propels the book, with his daring vision for the future of space.Filled with never-before-told stories of SpaceX’s turbulent beginning, Liftoff is a saga of cosmic proportions.

    After decades of global primacy, NASA has ended the space-shuttle program, cutting off its access to space. No astronauts will be launched in an American craft, from American soil, until the 2020s, and NASA may soon find itself eclipsed by other countries’ space programs.With his signature wit and thought-provoking insights, Neil deGrasse Tyson—one of our foremost thinkers on all things space—illuminates the past, present, and future of space exploration and brilliantly reminds us why NASA matters now as much as ever. As Tyson reveals, exploring the space frontier can profoundly enrich many aspects of our daily lives, from education systems and the economy to national security and morale. For America to maintain its status as a global leader and a technological innovator, he explains, we must regain our enthusiasm and curiosity about what lies beyond our world.Provocative, humorous, and wonderfully readable, Space Chronicles represents the best of Tyson’s recent commentary, including a must-read prologue on NASA and partisan politics. Reflecting on topics that range from scientific literacy to space-travel missteps, Tyson gives us an urgent, clear-eyed, and ultimately inspiring vision for the future.

    April 12, 1961. A top secret rocket site in the USSR. A young Russian sits inside a tiny capsule on top of the Soviet Union’s most powerful intercontinental ballistic missile—originally designed to carry a nuclear warhead—and blasts into the skies. His name is Yuri Gagarin. And he is about to make history. Travelling at almost 18,000 miles per hour—ten times faster than a rifle bullet—Gagarin circles the globe in just 106 minutes. From his windows he sees the earth as nobody has before, crossing a sunset and a sunrise, crossing oceans and continents, witnessing its beauty and its fragility. While his launch begins in total secrecy, within hours of his landing he has become a world celebrity – the first human to leave the planet. Beyond tells the thrilling story behind that epic flight on its 60th anniversary. It happened at the height of the Cold War as the US and USSR confronted each other across an Iron Curtain. Both superpowers took enormous risks to get a man into space first, the Americans in the full glare of the media, the Soviets under deep cover. Both trained their teams of astronauts to the edges of the endurable. In the end the race between them would come down to the wire.Drawing on extensive original research and the vivid testimony of eyewitnesses, many of whom have never spoken before, Stephen Walker unpacks secrets that were hidden for decades and takes the reader into the drama of one of humanity’s greatest adventures – to the scientists, engineers and political leaders on both sides, and above all to the American astronauts and their Soviet rivals battling for supremacy in the heavens.

    Nearly a half-century after Neil Armstrong walked on the moon, these Space Barons-most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen-are using Silicon Valley-style innovation to dramatically lower the cost of space travel, and send humans even further than NASA has gone. These entrepreneurs have founded some of the biggest brands in the world-Amazon, Microsoft, Virgin, Tesla, PayPal-and upended industry after industry. Now they are pursuing the biggest disruption of all: space. Based on years of reporting and exclusive interviews with all four billionaires, this authoritative account is a dramatic tale of risk and high adventure, the birth of a new Space Age, fueled by some of the world's richest men as they struggle to end governments' monopoly on the cosmos. The Space Barons is also a story of rivalry-hard-charging startups warring with established contractors, and the personal clashes of the leaders of this new space movement, particularly Musk and Bezos, as they aim for the moon and Mars and beyond.

    It is our twenty-first century New World; its explorers robots, shipped 350 million miles from Earth to uncover the distant planet’s secrets.Its most recent scout is Curiosity—a one-ton, Jeep-sized nuclear-powered space laboratory—which is now roving the Martian surface to determine whether the red planet has ever been physically capable of supporting life. In Red Rover, geochemist Roger Wiens, the principal investigator for the ChemCam laser instrument on the rover and veteran of numerous robotic NASA missions, tells the unlikely story of his involvement in sending sophisticated hardware into space, culminating in the Curiosity rover's amazing journey to Mars.In so doing, Wiens paints the portrait of one of the most exciting scientific stories of our time: the new era of robotic space exploration. Starting with NASA’s introduction of the Discovery Program in 1992, scrappier, more nimble missions became the order of the day, as manned missions were confined to Earth orbit, and behemoth projects went extinct. This strategic shift presented huge scientific opportunities, but tight budgets meant that success depended more than ever on creative engineering and human ingenuity. Beginning with the Genesis mission that launched his career, Wiens describes the competitive, DIY spirit of these robotic enterprises, from conception to construction, from launch to heart-stopping crashes and smooth landings.An inspiring account of the real-life challenges of space exploration, Red Rover vividly narrates what goes into answering the question: is there life elsewhere in the universe?

    While Sputnik immediately shocked the world, its long-term impact was even greater, for it profoundly changed the shape of the twentieth Century.Washington journalist Paul Dickson chronicles the dramatic events and developments leading up to and emanating from the Sputnik's launch a story that can only now be fully told with the recent release of previously classified documents. Sputnik offers a fascinating profile of the early American and Soviet space programs and a strikingly revised picture of the politics and personalities behind the facade of American's fledgling efforts to get into space.Although Sputnik was unmanned, its story is intensely human. Sputnik owed its success to many people, from the earlier visionary Konstantin Tsiolkovsky, whose rocket theories were ahead of their time, to the Soviet spokesmen strategically positioned around the world on the day the satellite was launched, who created one of the greatest public-relations events of all time. It’s chief designer, however the brillant Sergei Korolev remained a Soviet state secret until after his death.Equally hidden from view was the political intrigue dominating America's early space program, as the military services jockeyed for control and identity in a peacetime world. For years, former Nazi Wernher von Braun, who ran the U.S. Army's missile program, lobbied for his rocket team to be handed responsibility for the first Earth-orbiting satellite. He was outraged that Sputnik beat him and America into space. President Eisenhower, though, was secretly pleased that the Russians had launched first, because by orbiting over the United States, Sputnik established the principle of “freedom of space” that could justify the spy satellites he thought essential to monitor Soviet missile buildup. As Dickson reveals, Eisenhower was, in fact, much more a master of the Sputnik crisis than he appeared to be at the time and in subsequent accounts.

    Squyres dreamed up the mission in 1987, saw it through from conception in 1995 to a successful landing in 2004, and serves as the principal scientist of its $400 million payload. He has gained a rare inside look at what it took for rovers Spirit and Opportunity to land on the red planet in January 2004--and knows firsthand their findings.

    Like Undaunted Courage and D-Day, this is a tale of achieving the extraordinary against extraordinary odds.  As incredible as the "official" story of the space program is, the true, behind-the-scenes tale is more thrilling, more entertaining, and ultimately more ennobling.

    From dramatic, high-risk spacewalks to author Scott Parazynski’s death-defying quest to summit Mount Everest—his body ravaged by a career in space—readers will experience the life of an elite athlete, physician, and explorer.This intimate, compelling account offers a rare portrait of space exploration from the inside. A global nomad raised in the shadow of NASA’s Apollo missions, Parazynski never lost sight of his childhood dream to one day don a spacesuit and float outside the airlock. With deep passion, unbridled creativity, resilience, humility, and self-deprecation, Parazynski chases his dream of the ultimate adventure experience, again and again and again. In an era that transitioned from moon shots to the Space Shuttle, space station, and Mars research, Parazynski flies with John Glenn, tests jet packs, trains in Russia to become a cosmonaut, and flies five missions to outer space (including seven spacewalks) in his seventeen-year NASA career.An unparalleled, visceral opportunity to understand what it’s like to train for—and deploy to—a home in zero gravity, The Sky Below also portrays an astronaut’s engagement with the challenges of his life on Earth, including raising a beautiful autistic daughter and finding true love.

    Kennedy’s inspiring challenge, and America’s race to the moon.“We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win.”—President John F. KennedyOn May 25, 1961, JFK made an astonishing announcement: his goal of putting a man on the moon by the end of the decade. In this engrossing, fast-paced epic, Douglas Brinkley returns to the 1960s to recreate one of the most exciting and ambitious achievements in the history of humankind. American Moonshot brings together the extraordinary political, cultural, and scientific factors that fueled the birth and development of NASA and the Mercury, Gemini and Apollo projects, which shot the United States to victory in the space race against the Soviet Union at the height of the Cold War.Drawing on new primary source material and major interviews with many of the surviving figures who were key to America’s success, Brinkley brings this fascinating history to life as never before. American Moonshot is a portrait of the brilliant men and women who made this giant leap possible, the technology that enabled us to propel men beyond earth’s orbit to the moon and return them safely, and the geopolitical tensions that spurred Kennedy to commit himself fully to this audacious dream. Brinkley’s ensemble cast of New Frontier characters include rocketeer Wernher von Braun, astronaut John Glenn and space booster Lyndon Johnson.A vivid and enthralling chronicle of one of the most thrilling, hopeful, and turbulent eras in the nation’s history, American Moonshot is an homage to scientific ingenuity, human curiosity, and the boundless American spirit.

    What will happen if humanity makes contact with another civilization on a different planet? In The Contact Paradox, space journalist Keith Cooper tackles some of the myths and assumptions that underlie SETI--the Search for Extraterrestrial Intelligence.In 1974 a message was beamed towards the stars by the giant Arecibo telescope in Puerto Rico, a brief blast of radio waves designed to alert extraterrestrial civilizations to our existence. Of course, we don't know if such civilizations really exist. But for the past six decades a small cadre of researchers have been on a quest to find out, as part of SETI, the search for extraterrestrial intelligence.The silence from the stars is prompting some researchers, inspired by the Arecibo transmission, to transmit more messages into space, in an effort to provoke a response from any civilizations out there that might otherwise be staying quiet. However, the act of transmitting raises troubling questions about the process of contact. We look for qualities such as altruism and intelligence in extraterrestrial life, but what do these mean to humankind? Can we learn something about our own history when we explore what happens when two civilizations come into contact? Finally, do the answers tell us that it is safe to transmit, even though we know nothing about extraterrestrial life, or as Stephen Hawking argued, are we placing humanity in jeopardy by doing so?In The Contact Paradox, author Keith Cooper looks at how far SETI has come since its modest beginnings, and where it is going, by speaking to the leading names in the field and beyond. SETI forces us to confront our nature in a way that we seldom have before--where did we come from, where are we going, and who are we in the cosmic context of things? This book considers the assumptions that we make in our search for extraterrestrial life, and explores how those assumptions can teach us about ourselves.
