Space Biology and Medicine

Volume IV is devoted to examining the medical and associated organizational measures used to maintain the health of space crews and to support their performance before, during, and after space flight. These measures, collectively known as the medical flight support system, are important contributors to the safety and success of space flight. The contributions of space hardware and the spacecraft environment to flight safety and mission success are covered in previous volumes of the Space Biology and Medicine series. In Volume IV, we address means of improving the reliability of people who are required to function in the unfamiliar environment of space flight as well as the importance of those who support the crew. Please note that the extensive collaboration between Russian and American teams for this volume of work resulted in a timeframe of publication longer than originally anticipated. Therefore, new research or insights may have emerged since the authors composed their chapters and references. This volume includes a list of authors' names and addresses should readers seek specifics on new information. At least three groups of factors act to perturb human physiological homeostasis during space flight. All have significant influence on health, psychological, and emotional status, tolerance, and work capacity. The first and most important of these factors is weightlessness, the most specific and radical change in the ambient environment; it causes a variety of functional and structural changes in human physiology. The second group of factors precludes the constraints associated with living in the sealed, confined environment of spacecraft. Although these factors are not unique to space flight, the limitations they entail in terms of an uncomfortable environment can diminish the well-being and performance of crewmembers in space. The third group of factors includes the occupational and social factors associated with the difficult, critical nature of the crewmembers' work: the risks involved in space flight, changes in circadian rhythms, and intragroup interactions. The physical and emotional stress and fatigue that develop under these conditions also can disturb human health and performance. In addition to these factors, the risk also exists that crewmembers will develop various illnesses during flight. The risk of illness is no less during space flight than on Earth, and may actually be greater for some classes of diseases

A Fire to be Lighted: The Training of American Astronauts From 1959 to the Present

This study examines the training of American astronauts from the selection of the original Mercury astronauts in 1959 to the present, as crews of six work aboard the International Space Station. It makes the primary argument that through all of those years, the training sequence has successfully adapted to the challenges of preparing astronauts for flight far more than it has failed. It will examine in more detail than any previous publication how training devices for the Mercury, Gemini, Apollo, Skylab, Space Shuttle, and International Space Station programs helped astronauts to make this statement true. This study will also make the argument that the successful training of astronauts helped prove the value of sending them into space. Sessions at a variety of locales, from electronic flight simulators, to neutral buoyancy pools, to virtual reality laboratories have given astronauts the mental and physical flexibility in space missions that only they possess. In other words, they are not automatons, but rather people who can develop their skills through training. This study will demonstrate that when their missions began, those skills contributed to spectacular successes in space. Astronauts have returned a bevy of scientific data from their scientific experiments in Earth orbit and from their walks on the Moon during Apollo thanks to their trained eyes and minds. They have also serviced the Hubble Space Telescope and constructed an International Space Station that is longer than a football field thanks to their training. As the 21st century continues, astronauts will journey on bolder missions to near Earth asteroids, back to the Moon, and onto Mars. The instructors who train them for those missions, whether belonging to a government or a company, will benefit from reading this study because they will gain a sense of what training methods have worked historically and understand the tremendously strong track record of human accomplishments in space given adequate training

Turning Small Steps into Giant Leaps: NASA’s Genesis and Its Culmination in the Apollo Program

On July 16, 1969, NASA astronaut Neil Armstrong dropped himself onto the dusty surface of the Moon, momentarily followed by his lunar module pilot, Buzz Aldrin. It is simple to recognize the clear historical significance of the Apollo moon landings. It can also be easy, however, to overlook the work of thousands of individuals and decades of development that culminated in a lunar voyage. Because the moon landings were unprecedented, the hardware required had to be developed from scratch and mission protocol had to be written. Additionally, the United States was competing against its Cold War adversary, the Soviet Union, which had already thrusted a manmade satellite into orbit. The National Aeronautics and Space Administration (NASA) was created in 1958 to coordinate the space program of the United States. NASA was a conglomeration of various military personnel, facilities, and technology as well as an experimental aeronautics regulatory agency known as the National Advisory Committee for Aeronautics (NACA). As its first steps in manned space exploration, NASA began Project Mercury. It would loft America’s first astronauts into space and set the stage for further projects that ultimately led to the Apollo moon landings. Even though Project Gemini immediately preceded Project Apollo, the Mercury program set a course for the young NASA to eventually reach the Moon. The creation of NASA from military assets and NACA, its early administrative personnel and structure, as well as its first steps in Project Mercury were foundational for later success achieved by Project Apollo

Wings in Orbit: Scientific and Engineering Legacies of the Space Shuttle, 1971-2010

The Space Shuttle is an engineering marvel perhaps only exceeded by the station itself. The shuttle was based on the technology of the 1960s and early 1970s. It had to overcome significant challenges to make it reusable. Perhaps the greatest challenges were the main engines and the Thermal Protection System. The program has seen terrible tragedy in its 3 decades of operation, yet it has also seen marvelous success. One of the most notable successes is the Hubble Space Telescope, a program that would have been a failure without the shuttle's capability to rendezvous, capture, repair, as well as upgrade. Now Hubble is a shining example of success admired by people around the world. As the program comes to a close, it is important to capture the legacy of the shuttle for future generations. That is what "Wings In Orbit" does for space fans, students, engineers, and scientists. This book, written by the men and women who made the program possible, will serve as an excellent reference for building future space vehicles. We are proud to have played a small part in making it happen. Our journey to document the scientific and engineering accomplishments of this magnificent winged vehicle began with an audacious proposal: to capture the passion of those who devoted their energies to its success while answering the question "What are the most significant accomplishments?" of the longestoperating human spaceflight program in our nation s history. This is intended to be an honest, accurate, and easily understandable account of the research and innovation accomplished during the era

This New Ocean: A History of Project Mercury

When Congress created the National Aeronautics and Space Administration (NASA) in 1958, it charged NASA with the responsibility "to contribute materially to . . . the expansion of human knowledge of phenomena in the atmosphere and space" and "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." NASA wisely interpreted this mandate to include responsibility for documenting the epochal progress of which it is the focus. The result has been the development of a historical program by NASA as unprecedented as the task of extending man's mobility beyond his planet. This volume is not only NASA's accounting of its obligation to disseminate information to our current generation of Americans. It also fulfills, as do all of NASA's future-oriented scientific-technological activities, the further obligation to document the present as the heritage of the future. The wide-ranging NASA history program includes chronicles of day-to-day space activities; specialized studies of particular fields within space science and technology; accounts of NASA's efforts in organization and management, where its innovations, while less known to the public than its more spectacular space shots, have also been of great significance; narratives of the growth and expansion of the space centers throughout the country, which represent in microcosm many aspects of NASA's total effort; program histories, tracing the successes- and failures- of the various projects that mark man's progress into the Space Age; and a history of NASA itself, incorporating in general terms the major problems and challenges, and the responses thereto, of our entire civilian space effort. The volume presented here is a program history, the first in a series telling of NASA's pioneering steps into the Space Age. It deals with the first American manned-spaceflight program: Project Mercury. Although some academicians might protest that this is "official" history, it is official only in the fact that it has been prepared and published with the support and cooperation of NASA. It is not "official" history in the sense of presenting a point of view supposedly that of NASA officialdom-if anyone could determine what the "point of view" of such a complex organism might be. Certainly, the authors were allowed to pursue their task with the fullest freedom and in accordance with the highest scholarly standards of the history profession
