Description :


Winner of the Graywolf Press Nonfiction Prize, a breathtaking elegy to the waning days of human spaceflight as we have known it In the 1960s, humans took their first steps away from Earth, and for a time our possibilities in space seemed endless. 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?

Description :


A wildly entertaining account of the rules, lessons, procedures, and experiences of space travel, How to Astronaut is a book that will appeal to anyone— male or female, young or old—with even a passing interest in space. Written by Col. Terry Virts, a former astronaut, space shuttle pilot, and International Space Station commander who spent 200 consecutive days in space, it answers all of our curious questions and much more: Here’s how to survive that first brush with weightlessness (in the so-called vomit comet); the nearly indescribable thrill of a first blastoff; managing the daily tasks—eating, bathing, doing chores, going to the bathroom— that are anything but ordinary when you’re orbiting the earth at 17,000 miles per hour; how to don your space suit and head out to work on a spacewalk (“alone in the vacuum”); how to prepare for emergencies of all kinds, from managing “space brain” to dealing with a dead crew member; and what it’s like to return to Earth, including something as seemingly simple as walking after spending six months in zero-g. A born storyteller, Virts reveals the often-untold side of space travel in 51 short chapters filled with a mix of you-are-there detail, a dose of science made simple, and the inherent drama of describing something few will ever know firsthand.

Description :


Nuclear-powered Earth-orbital-launch probes can place greater payloads in orbit about Mars than chemical vehicles if reactor power exceeds 50 mw. Suitable reactor powers for this missionARE ABOUT 150, 400, AND 1000 MW FOR 33,000-, 81,000-, AND 200,000-LB VEHICLES, RESPECTIVELY. Whereas a 33,000-lb vehicle requires greater than a 200-day coast, a 145-day coast is feasible for an 81,000-lb vehicle. A hydrogen temperature of 4000 F in the nozzle appears to be a good compromise. Use of a solid-propellant rocket to achieve an orbit about Mars from coast yields no payload advantage. Using optimum firing dates, a 33,000-lb vehicle could orbit an acceptable payload about Mars, and an 81,000-lb vehicle could land freight on Mars. (Author).

Description :


An astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

Description :


This book shares a range of new and diverse insights on On-Orbit Servicing (OOS), and examines its implications especially from political, legal, economic, and security perspectives. OSS has been evolving rapidly and presents both challenges and opportunities, such as in-space repairs, refuelling, refurbishment of spacecraft and servicing satellites, which could play a critical role in extending satellite lifecycles, while also representing a valuable next step in debris mitigation. At the same time, many legal questions have arisen in connection with OOS: the need to prevent hostile actions under the pretext of OSS; the distinction between governmental and non-governmental OOS operators; the status of re-worked and recycled space objects; the issue of control in terms of operations performed in orbit, i.e., in the international sphere; the status of objects manufactured in orbit and applicable law, including liability and registration; and the impacts on insurance law and risk management. Finally, the book examines the implications of OOS for emerging space actors in the Global South, and recommends a paradigm shift to help developing countries fully recognise the necessity and urgency of being involved in discussions on OSS, as opposed to leaving it up to the developed space actors. This book will be of great interest to practitioners, academics, and students working in the space sector and related fields.

Everyone seems to be thinking about Mars nowadays. NASA plans to have humans on Mars by 2030 while SpaceX wants to do it sooner, by 2024. Mars is a common theme in Hollywood. There are movies like The Martian and Life that speculate how life may be on the red planet. None of these movies, however, seems to address the elephant in the room—how will humans survive long-term on Mars? The Mars atmosphere is mostly comprised of carbon monoxide and its surface is too cold for human life. The gravity is 38% that of Earth. This leaves the question of how a human being can survive such an environment. Traveling to Mars is an easy task, as the journey will only take 260 days when the two planets are closest to each other. After arriving, the challenge is landing on the surface. What landing system is safe for colonists and astronauts? By 2007, scientists had four landing suggestions; the Legged Standing System, Sky-Crane Landing System, Airbag Landing System and lastly, the Touchdown Sensing. As of 2017, scientists had already come up with more ways for landing such as diving into the Martian atmosphere and skirting closer to the surface. NASA is already thinking of the kind of habitation that will help colonists survive on Mars. In 2016, six companies had started designing possible habitat prototypes. All these prototypes are likely to be similar in a few ways—they should be self-sustaining, able to support life for a long period of time without help from Earth, and have a seal against Mars’s thin atmosphere.

Heat Rises Leaving Earth with a burst of speed and a trail of dark exhaust, the Saturnian Space Agency performed what had become routine: Eight people were on their way to relieve the entire crew of a low- Earth orbit space research station. Unbeknownst to the agencys flight surgeons or to the crew itself, a hypervirulent bacterium had hitched a ride. For one week, both crews mingled and then the crew that had been relieved flew home for the usual six month break. This time, though, they would not be returning to the space station. A superbug had arrived with a healthy-looking crewmember. Zander, our very own Typhoid Mary, brought with her death in the form of a pan-resistant superinfection Salmonella typhi, the bacterium that causes typhoid fever. Ive read your reports. Youve briefed me on-station. I relieve you, Zander stated formally. I stand relieved, Echo spoke just as formally but was slouched in a chair, and then she clicked-off comms to Earth. Now, she whooped, lets get this party started!

The Hubble Space Telescope has produced the most stunning images of the cosmos humanity has ever seen. It has transformed our understanding of the universe around us, revealing new information about its age and evolution, the life cycle of stars, and the very existence of black holes, among other startling discoveries. But it took an amazing amount of work and perseverance to get the first space telescope up and running. The Universe in a Mirror tells the story of this telescope and the visionaries responsible for its extraordinary accomplishments. Robert Zimmerman takes readers behind the scenes of one of the most ambitious scientific instruments ever sent into space. After World War II, astronomer Lyman Spitzer and a handful of scientists waged a fifty-year struggle to build the first space telescope capable of seeing beyond Earth's atmospheric veil. Zimmerman shows how many of the telescope's advocates sacrificed careers and family to get it launched, and how others devoted their lives to Hubble only to have their hopes and reputations shattered when its mirror was found to be flawed. This is the story of an idea that would not die--and of the dauntless human spirit. Illustrated with striking color images, The Universe in a Mirror describes the heated battles between scientists and bureaucrats, the perseverance of astronauts to repair and maintain the telescope, and much more. Hubble, and the men and women behind it, opened a rare window onto the universe, dazzling humanity with sights never before seen. This book tells their remarkable story. A new afterword updates the reader on the May 2009 Hubble service mission and looks to the future of astronomy, including the prospect of a new space telescope to replace Hubble.

From September 2007 to June 2008 the Space Studies Board conducted an international public seminar series, with each monthly talk highlighting a different topic in space and Earth science. The principal lectures from the series are compiled in Forging the Future of Space Science. The topics of these events covered the full spectrum of space and Earth science research, from global climate change, to the cosmic origins of life, to the exploration of the Moon and Mars, to the scientific research required to support human spaceflight. The prevailing messages throughout the seminar series as demonstrated by the lectures in this book are how much we have accomplished over the past 50 years, how profound are our discoveries, how much contributions from the space program affect our daily lives, and yet how much remains to be done. The age of discovery in space and Earth science is just beginning. Opportunities abound that will forever alter our destiny.

Description :


Since the beginning of space flight, the collision hazard in Earth orbit has increased as the number of artificial objects orbiting the Earth has grown. Spacecraft performing communications, navigation, scientific, and other missions now share Earth orbit with spent rocket bodies, nonfunctional spacecraft, fragments from spacecraft breakups, and other debris created as a byproduct of space operations. Orbital Debris examines the methods we can use to characterize orbital debris, estimates the magnitude of the debris population, and assesses the hazard that this population poses to spacecraft. Potential methods to protect spacecraft are explored. The report also takes a close look at the projected future growth in the debris population and evaluates approaches to reducing that growth. Orbital Debris offers clear recommendations for targeted research on the debris population, for methods to improve the protection of spacecraft, on methods to reduce the creation of debris in the future, and much more.
