Includes Foreword, Acronyms and Abbreviations, Introduction, The Chronology, and Index. This book chronicles the 154 extravehicular activities conducted from March 1965 to April 1997. It is intended to make clear the crucial role played by EVA in the history of spaceflight, as well as to chronicle the large body of EVA "lessons learned." This is the seventh publication in a new series of special studies prepared by the NASA History Office. This monograph is designed to provide a wide variety of investigations relative to the history of aeronautics and space. These publications are intended to be tightly focused in terms of subject, relatively short in length, and reproduced in an inexpensive format to allow timely and broad dissemination to those interested in aerospace history. David S. F. Portree is an award-winning independent science writer and historian. He holds an M.S. in History and is a former Senior Technical Writer and Historian at NASA Johnson Space Center. Portree has written several scholarly histories for NASA, including Mir Hardware Heritage (1995), Walking to Olympus: an EVA Chronology (1997), Orbital Debris: A Chronology (1999), and Humans to Mars: Fifty Years of Mission Planning (2001). Walking to Olympus received the 1998 Napolitano Book Award from the International Academy of Astronautics. One of the most significant activities conducted in space takes place when human beings depart their spacecraft and travel about and perform work in a spacesuit. Extravehicular activities (EVA) require some of the most complex technical skills, sophisticated technologies, and human capabilities of all missions undertaken in space. The first of these EVAs took place on 18 March 1965 during the Soviet Union s Voskhod 2 orbital mission when cosmonaut Alexei Leonov first departed the spacecraft in Earth orbit to test the concept. In June of 1965, during the flight of Gemini 4, Edward White II, performed the first EVA by an American. Since that time hundreds of hours have been amassed by humans conducting EVAs in both Earth orbit and on the lunar surface. Between that time and April 1997, when Jerry Linenger conducted an EVA with Vladimir Tsibliyev as part of International Space Station Phase I, 154 EVAs have been undertaken. These total EVAs have not only accomplished significant work in space, work impossible through any other means, but also yielded enormous knowledge, skills, and experience among the astronaut and cosmonaut corps about how to perform meaningful work beyond the confines of Earth s atmosphere. Walking to Olympus: An EVA Chronology, by David S.F. Portree and Robert C. Treviño, is a comprehensive chronicle of all of the EVAs conducted since the dawn of the space age. Because history is so important in helping to chart the direction for the future, this monograph s publication is especially significant because the building of the International Space Station near the end of this century will require many more hours of EVA than has been previously undertaken altogether. One of our goals for publishing this monograph at this time is to help inform officials and the general public of what EVAs have been done before, what they accomplished, and what hurdles had to be surmounted to accomplish them.
