    Toward a History of the Space Shuttle An Annotated Bibliography Part 2, 1992–2011 Monographs in Aerospace History, Number 49 TOWARD A HISTORY OF THE SPACE SHUTTLE AN ANNOTATED BIBLIOGRAPHY, PART 2 (1992–2011) Compiled by Malinda K. Goodrich Alice R. Buchalter Patrick M. Miller of the Federal Research Division, Library of Congress NASA History Program Office Office of Communications NASA Headquarters Washington, DC Monographs in Aerospace History Number 49 August 2012 NASA SP-2012-4549 Library of Congress – Federal Research Division Space Shuttle Annotated Bibliography PREFACE This annotated bibliography is a continuation of Toward a History of the Space Shuttle: An Annotated Bibliography, compiled by Roger D. Launius and Aaron K. Gillette, and published by NASA as Monographs in Aerospace History, Number 1 in December 1992 (available online at http://history.nasa.gov/Shuttlebib/contents.html). The Launius/Gillette volume contains those works published between the early days of the United States’ manned spaceflight program in the 1970s through 1991. The articles included in the first volume were judged to be most essential for researchers writing on the Space Shuttle’s history. The current (second) volume is intended as a follow-on to the first volume. It includes key articles, books, hearings, and U.S. government publications published on the Shuttle between 1992 and the end of the Shuttle program in 2011. The material is arranged according to theme, including: general works, precursors to the Shuttle, the decision to build the Space Shuttle, its design and development, operations, and management of the Space Shuttle program. Other topics covered include: the Challenger and Columbia accidents, as well as the use of the Space Shuttle in building and servicing the Hubble Space Telescope and the International Space Station; science on the Space Shuttle; commercial and military uses of the Space Shuttle; and the Space Shuttle’s role in international relations, including its use in connection with the Soviet Mir space station.

    PART III. REFLECTIONS ON THE SPACE AGE ~ CHAPTER 18 AM ELANCHOLIC SPACE AGE ANNIVERSARY Walter A. McDougall y sincere thanks to Steven Dick, Roger Launius, and the entire space Mhistory and space policy communities for inviting an old dilettante like myself to this event. Some of you good people I’ve not seen since we commemorated the 40th anniversary of Sputnik, and some of you doubtless I shall not have occasion to meet again. That alone makes this a somewhat melancholy affair for me. But I also have a sense that the 50th anniversary of the birth of the Space Age is draped with a certain melancholy. Do you sense a mood of disappointment, frustration, impatience over the failure of the human race to achieve much more than the minimum extrapolations made back in the 1950s, and considerably less than the buoyant expectations expressed as late as the 1970s? After all, one modest prediction went like this: “There are few today who do not look forward with feelings of confidence that spaceflight will some day be accomplished. All that we require is to make rocket motors somewhat larger than those already in existence . the pooling of skills already available, and a good deal of money . We may reasonably suppose that a satellite vehicle is entirely practicable now and that travel to the moon is attainable in the next fifty years.”1 That was Dr. Hugh Dryden in 1953, on the occasion of the 50th anniversary of the Wright brothers’ flight. (Indeed, if all of us interviewed by the media this month have accomplished anything I think we have at last disabused journalists of the notion that the Eisenhower administration was “surprised” by the first satellite launch.) But what that means is that all the satellites, space probes, and human missions launched over 50 years amount pretty much to what Dryden took for granted would happen.

    Exploration, Discovery, and Culture NASA’S Role in History

    Chapter 23 Exploration, Discovery, and Culture NASA’s Role in History Steven J. Dick Introduction: Space Exploration in Context Like the facets of a jewel, the overall importance of NASA and the Space Age over the last 50 years may be considered from many viewpoints, ranging from the geopolitical and technological to the educational and scientific. But no facet is more central than exploration, a concept that encompasses most of the other possibilities and arguably constitutes one of the main engines of human culture, spanning millennia. In its simplest and purest form, the Space Age may be seen as the latest episode in a long tradition of human exploration. Surveying the vast panoply of history, historians have often found “symmetry in the narrative arc of the Great Ages of Discovery” or traced that tradition back even to the Paleolithic Era in an attempt to find a “global historical context” for the Space Age.1 1.
