Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    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.

    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.

    The incredible projects described here were not merely flights of fancy dreamed up by space enthusiasts, but actual missions planned by leading aeronautical engineers. Some were designed but not built; others were built but not flown; and a few were flown to failure but little reported: A giant rocket that would use atomic bombs as propulsion (never mind the fallout), military bases on the moon that could target enemies on earth with nuclear weapons, a scheme to spray-paint the lenses of Soviet spy satellites in space, the rushed Soyuz 1 spacecraft that ended with the death of its pilot, the near-disaster of the Apollo 11 moon landing, the mysterious Russian space shuttle that flew only once and was then scrapped--these are just some of the unbelievable tales that Pyle has found in once top-secret documents as well as accounts that were simply lost for many decades. These stories, complimented by many rarely-seen photos and illustrations, tell of a time when nothing was too off-the-wall to be taken seriously, and the race to the moon and the threat from the Soviet Union trumped all other considerations. Readers will be fascinated, amused, and sometimes chilled.

    But in a time of austerity and in the wake of high-profile disasters like Challenger, that dream has ended. In early 2011, Margaret Lazarus Dean traveled to Cape Canaveral for NASA's last three space shuttle launches in order to bear witness to the end of an era. With Dean as our guide to Florida's Space Coast and to the history of NASA, Leaving Orbit takes the measure of what American spaceflight has achieved while reckoning with its earlier witnesses, such as Norman Mailer, Tom Wolfe, and Oriana Fallaci. Along the way, Dean meets NASA workers, astronauts, and space fans, gathering possible answers to the question: What does it mean that a spacefaring nation won't be going to space anymore?

    It is a one-ton robot with two brains, seventeen cameras, six wheels, nuclear power, and a laser beam on its head. No one human understands how all of its systems and instruments work. This essential reference to the Curiosity mission explains the engineering behind every system on the rover, from its rocket-powered jetpack to its radioisotope thermoelectric generator to its fiendishly complex sample handling system. Its lavishly illustrated text explains how all the instruments work -- its cameras, spectrometers, sample-cooking oven, and weather station -- and describes the instruments' abilities and limitations. It tells you how the systems have functioned on Mars, and how scientists and engineers have worked around problems developed on a faraway planet: holey wheels and broken focus lasers. And it explains the grueling mission operations schedule that keeps the rover working day in and day out.

    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.

    When Neil Armstrong and Buzz Aldrin first set foot on lunar soil, the moon ceased to be a place of mystery and myth. It became a destination.Now, on the fiftieth anniversary of that journey, Moonbound tells the monumental story of the moon and the men who went there first. With vibrant images and meticulous attention to detail, Jonathan Fetter-Vorm conjures the long history of the visionaries, stargazers, builders, and adventurers who sent Apollo 11 on its legendary voyage.From the wisdom of the Babylonians to the intrigues of the Cold War, from the otherworldly discoveries of Galileo to the dark legacy of Nazi atrocities, from the exhilarating trajectories of astronauts―recounted in their own words―to the unsung brilliance of engineers working behind the scenes, Moonbound captures the grand arc of the Space Age in a graphic history of unprecedented scope and profound lyricism.

    As with the previous edition, coauthored with Oscar Biblarz, the Eighth Edition of "Rocket Propulsion Elements" offers a thorough introduction to basic principles of rocket propulsion for guided missiles, space flight, or satellite flight. It describes the physical mechanisms and designs for various types of rockets' and provides an understanding of how rocket propulsion is applied to flying vehicles.Updated and strengthened throughout, the Eighth Edition explores:The fundamentals of rocket propulsion, its essential technologies, and its key design rationaleThe various types of rocket propulsion systems, physical phenomena, and essential relationshipsThe latest advances in the field such as changes in materials, systems design, propellants, applications, and manufacturing technologies, with a separate new chapter devoted to turbopumpsLiquid propellant rocket engines and solid propellant rocket motors, the two most prevalent of the rocket propulsion systems, with in-depth consideration of advances in hybrid rockets and electrical space propulsionComprehensive and coherently organized, this seminal text guides readers evenhandedly through the complex factors that shape rocket propulsion, with both theory and practical design considerations. Professional engineers in the aerospace and defense industries as well as students in mechanical and aerospace engineering will find this updated classic indispensable for its scope of coverage and utility.

    He wanted to give his girlfriend the moon. Literally.  Thad convinced his girlfriend and another female accomplice, both NASA interns, to break into an impregnable laboratory at NASA—past security checkpoints, an electronically locked door with cipher security codes, and camera-lined hallways—and help him steal the most precious objects in the world: the moon rocks. But what does one do with an item so valuable that it’s illegal even to own? And was Thad Roberts—undeniably gifted, picked for one of the most competitive scientific posts imaginable, a possible astronaut—really what he seemed? Mezrich has pored over thousands of pages of court records, FBI transcripts, and NASA documents and has interviewed most of the participants in the crime to reconstruct this Ocean’s Eleven–style heist, a madcap story of genius, love, and duplicity that reads like a Hollywood thrill ride.

    Rather, they recruited an elite group of young women who, with only pencil, paper, and mathematical prowess, transformed rocket design, helped bring about the first American satellites, and made the exploration of the solar system possible. For the first time, Rise of the Rocket Girls tells the stories of these women--known as "human computers"--who broke the boundaries of both gender and science. Based on extensive research and interviews with all the living members of the team, Rise of the Rocket Girls offers a unique perspective on the role of women in science: both where we've been, and the far reaches of space to which we're heading.

    Waugh looks at every aspect of time - from the Big Bang, through clock time and calendars to the end of time. Drawing on Waugh's polymathic knowledge of art, music, literature, science and social history, this is a hugely entertaining examination of the big questions about time: how were seconds, minutes and hours agreed; how were the various calendars arrived at and why are there twelve months in a year and seven days in a week?

    She was in the first class of women to earn pilot’s wings at Vance Air Force Base and was their first female instructor pilot. She was only the second woman admitted to the Air Force’s elite Test Pilot Program at Edwards Air Force Base. NASA had such confidence in her skills as a leader and pilot that she was entrusted to command the first shuttle mission after the Columbia disaster, returning the US to spaceflight after a two-year hiatus. Since retiring from the Air Force and NASA, she has served on numerous corporate boards and is an inspirational speaker about space exploration and leadership.Eileen Collins is among the most recognized and admired women in the world, yet this is the first time she has told her story in a book. It is a story not only of achievement and overcoming obstacles but of profound personal transformation. The shy, quiet child of an alcoholic father and struggling single mother, who grew up in modest circumstances and was an unremarkable student, she had few prospects when she graduated from high school, but she changed her life to pursue her secret dream of becoming an astronaut. She shares her leadership and life lessons throughout the book with the aim of inspiring and passing on her legacy to a new generation.

    But Neil Armstrong and Sally Ride would have never made history, and humankind would not have touched the stars, if not for the men and women on the ground who lit the fuse that launched the first rockets.Enthralled as a boy by the exploits of Flash Gordon and the novels of Robert Heinlein and Arthur C. Clarke—who put the science in science fiction—James French became one of the original unsung engineers of America’s groundbreaking space program. His fascinating memoir offers an up-close-and-technical look at building, testing, and perfecting the pioneering Saturn rockets and original lunar landing module, and he shares true tales, both humorous and harrowing, of life—and near death—on the front lines of scientific exploration.If you’ve ever said, “It’s not rocket science,” you’re right. It’s rocket engineering—and here’s your chance to marvel at how it changed the world and made it possible to explore all that lies beyond Earth. James R French graduated from MIT in 1958 with a degree of BSME Specializing in Propulsion. His first job was with Rocketdyne Division of North American Aviation where he worked on developmental testing of H-1 engines and combustion devices hardware for F-1 and J-2 engines used in Saturn 5. Mr. French has also worked at TRW Systems, where he was Lead Development Test Engineer on the Lunar Module Descent Engine, and Jet Propulsion Laboratory where he was Advanced Planetary studies Manager as well as Chief Engineer for the SP-100 Space Nuclear Power System and worked on Mariners 5, 6, 7, 8, and 9; Viking 1 & 2 and Voyager 1 & 2. . In 1986, he helped found American Rocket Co., a commercial launch company.Since 1987, Mr. French has been consultant to a variety of aerospace companies, SDIO, NASA, and USAF. He has participated in various startup companies in the private space flight arena and currently consults extensively to Blue Origin. Mr. French is co-author with Dr. Michael Griffin of the best-selling text Space Vehicle Design, published by AIAA. The second edition of the book has received the Summerfield Book Award for 2008. Mr. French is a Fellow of both AIAA and the British Interplanetary Society and a 50+ year member of AIAA. He has held several Technical Committee and other posts in AIAA. Cover design by Evan Twohy
