Available in PDF, EPUB and Kindle. Book excerpt: This volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X-15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it addresses the re-entry problem, which came to the forefront during the mid-1950s, showing how work in this area supported the manned space program and contributed to the development of the orbital shuttle. Subsequent chapters explore the fading of scramjet studies and the rise of the National Aerospace Plane (NASP) program of 1985–95, which sought to lay groundwork for single-stage vehicles. The program's ultimate shortcomings — in terms of aerodynamics, propulsion, and materials — are discussed, and the book concludes with a look at hypersonics in the post-NASP era, including the development of the X-33 and X-34 launch vehicles, further uses for scramjets, and advances in fluid mechanics. Clearly, ongoing research in hypersonics has yet to reach its full potential, and readers with an interest in aeronautics and astronautics will find this book a fascinating exploration of the field's history and future.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "To commemorate the 50th anniversary of the first successful planetary mission, Mariner 2 sent to Venus in 1962, the NASA History Program Office, the Division of Space History at the National Air and Space Museum, NASA's Science Mission Directorate, and the Jet Propulsion Laboratory organized a symposium. "Solar System Exploration @ 50" was held in Washington, D.C., on 25-26 October 2012. The purpose of this symposium was to consider, over the more than 50-year history of the Space Age, what we have learned about the other bodies of the solar system and the processes by which we have learned it. Symposium organizers asked authors to address broad topics relating to the history of solar system exploration such as various flight projects, the development of space science disciplines, the relationship between robotic exploration and human spaceflight, the development of instruments and methodologies for scientific exploration, as well as the development of theories about planetary science, solar system origins and implications for other worlds. The papers in this volume provide a richly textured picture of important developments - and some colorful characters - in a half century of solar system exploration. A comprehensive history of the first 50 years of solar system exploration would fill many volumes. What readers will find in this volume is a collection of interesting stories about money, politics, human resources, commitment, competition and cooperation, and the "faster, better, cheaper" era of solar system exploration"--

Book excerpt: On the 20th anniversary of the first human landing on the Moon, President George H.W. Bush stood atop the steps of the National Air and Space Museum in Washington, D.C. and proposed a long-range human exploration plan that included the successful construction of an orbital space station, a permanent return to the Moon, and a mission to Mars. This enterprise became known as the Space Exploration Initiative (SEI). The president charged the newly reestablished National Space Council with providing concrete alternatives for meeting these objectives. To provide overall focus for the new initiative, Bush later set a thirty-year goal for a crewed landing on Mars. Within a few short years after this Kennedyesque announcement, however, the initiative had faded into history the victim of a flawed policy process and a political war fought on several different fronts. The story of this failed initiative was a tale of organizational, cultural, and personal confrontation by key protagonists and critical battles. Some commentators have argued that SEI was doomed to fail, due primarily to the immense budgetary pressures facing the nation during the early 1990s. The central thesis of Mars Wars: The Rise and Fall of the Space Exploration Initiative suggests, however, that failure was not predetermined. Instead, it was the result of a deeply flawed decision-making process that failed to develop (or even consider) policy options that may have been politically acceptable given the existing political environment.

Download or read book The Case For Mars written by Robert Zubrin and published by Simon and Schuster. This book was released on 2012-12-11 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of human history Mars has been an alluring dream; the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with illustrations, photographs, and engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions. It explains step-by-step how we can use present-day technology to send humans to Mars within ten years; actually produce fuel and oxygen on the planet's surface with Martian natural resources; how we can build bases and settlements; and how we can one day "terraform" Mars; a process that can alter the atmosphere of planets and pave the way for sustainable life.

Download or read book Eating Disorders Anonymous written by Eating Disorders Anonymous (EDA) and published by GŸrze Books. This book was released on 2016-11-21 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eating Disorders Anonymous: The Story of How We Recovered from Our Eating Disorders presents the accumulated experience, strength, and hope of many who have followed a Twelve-Step approach to recover from their eating disorders. Eating Disorders Anonymous (EDA), founded by sober members of Alcoholics Anonymous (AA), have produced a work that emulates the “Big Book” in style and substance. EDA respects the pioneering work of AA while expanding its Twelve-Step message of hope to include those who are religious or seek a spiritual solution, and for those who are not and may be more comfortable substituting “higher purpose” for the traditional “Higher Power.” Further, the EDA approach embraces the development and maintenance of balance and perspective, rather than abstinence, as the goal of recovery. Initial chapters provide clear directions on how to establish a foothold in recovery by offering one of the founder’s story of hope, and collective voices tell why EDA is suitable for readers with any type of problem eating, including: anorexia nervosa, bulimia, binge eating, emotional eating, and orthorexia. The text then explains how to use the Twelve Steps to develop a durable and resilient way of thinking and acting that is free of eating disordered thoughts and behaviors, including how to pay it forward so that others might have hope of recovery. In the second half of the text, individual contributors share their experiences, describing what it was like to have an eating disorder, what happened that enabled them to make a start in recovery, and what it is like to be in recovery. Like the “Big Book,” these stories are in three sections: Pioneers of EDA, They Stopped in Time, and They Lost Nearly All. Readers using the Twelve Steps to recover from other issues will find the process consistent and reinforcing of their experiences, yet the EDA approach offers novel ideas and specific guidance for those struggling with food, weight and body image issues. Letters of support from three, highly-regarded medical professionals and two, well-known recovery advocates offer reassurance that EDA’s approach is consistent with that supported by medical research and standards in the field of eating disorders treatment. Intended as standard reading for members who participate in EDA groups throughout the world, this book is accessible and appropriate for anyone who wants to recover from an eating disorder or from issues related to food, weight, and body image.
