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?

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.

"There's something intriguing to be learned on practically every page... [How to Astronaut] captures the details of an extraordinary job and turns even the mundane aspects of space travel into something fascinating."––Publishers Weekly Ride shotgun on a trip to space with astronaut Terry Virts. A born stroyteller with a gift for the surprising turn of phrase and eye for the perfect you-are-there details, he captures all the highs, lows, humor, and wonder of an experience few will ever know firsthand.

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.

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.

Old Earth has nothing left for us, and so it is time for a new beginning. Cross galaxies, traverse light years and find yourself in a world where you can be the centre of your own universe. Welcome to New Earth. Never look back. Vela, the revered and celebrated architect of this new society, has recently been avoiding her public duties in favour of visiting the Old Earth Museum and the company of its Security Guard. As the final migrants arrive, she is becoming increasingly obsessed by her memories, and questions are growing about her sanity. Leaving Planet Earth is a site-responsive promenade production on an epic scale. Tracing the story of humanity's first migration into space, it asks fundamental questions about our connection to this planet. Should we leave this world, and if so, who will endure and at what cost?

Orbital Mechanics for Engineering Students, Second Edition, provides an introduction to the basic concepts of space mechanics. These include vector kinematics in three dimensions; Newton’s laws of motion and gravitation; relative motion; the vector-based solution of the classical two-body problem; derivation of Kepler’s equations; orbits in three dimensions; preliminary orbit determination; and orbital maneuvers. The book also covers relative motion and the two-impulse rendezvous problem; interplanetary mission design using patched conics; rigid-body dynamics used to characterize the attitude of a space vehicle; satellite attitude dynamics; and the characteristics and design of multi-stage launch vehicles. Each chapter begins with an outline of key concepts and concludes with problems that are based on the material covered. This text is written for undergraduates who are studying orbital mechanics for the first time and have completed courses in physics, dynamics, and mathematics, including differential equations and applied linear algebra. Graduate students, researchers, and experienced practitioners will also find useful review materials in the book. NEW: Reorganized and improved discusions of coordinate systems, new discussion on perturbations and quarternions NEW: Increased coverage of attitude dynamics, including new Matlab algorithms and examples in chapter 10 New examples and homework problems

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.
