Walking to Olympus: An EVA Chronology David S. F. Portree and Robert C. Treviño Monographs in Aerospace History Series #7 October 1997 Walking to Olympus: An EVA Chronology David S. F. Portree and Robert C. Treviño NASA History Office Code Z NASA Headquarters Washington DC 20546 Monographs in Aerospace History Series #7 October 1997 Foreword 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 Unions Voskhod 2 orbital mission when cosmonaut Alexei Leonov first departed the space- craft 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 Earths atmo- sphere. 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 monographs 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. This is the seventh publication in a new series of special studies prepared by the NASA History Office. The Monographs in Aerospace History series 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. Suggestions for additional publications in the Monographs in Aerospace History series are welcome. ROGER D.

a view of Earth once reserved for Apollo, Zeus, and other denizens of Mt. Olympus. During humanity’s first extravehicular activity (EVA), Alexei Leonov floated above Gibraltar, the rock ancient seafarers saw as the gateway to the great unknown Atlantic. The symbol- ism was clear - Leonov stepped past a new Gibraltar when he stepped into space. More than 32 years and 154 EVAs later, Jerry Linenger conducted an EVA with Vladimir Tsibliyev as part of International Space Station Phase I. They floated together above Gibraltar. Today the symbolism has new meaning - humanity is starting to think of stepping out of Earth orbit, space travel’s new Gibraltar, and perhaps obtaining a new olympian view - a close-up look at Olympus Mons on Mars. Walking to Olympus: An EVA Chronology chronicles the 154 EVAs 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.” Russia and the U.S. define EVA differently. Russian cosmonauts are said to perform EVA any time they are in vacuum in a space suit. A U.S. astronaut must have at least his head outside his spacecraft before he is said to perform an EVA. The difference is based in differing spacecraft design philoso-
