The book explores the era of space collaboration (from 1970 to the present). This period has been largely ignored by historians in favor of a focus on the earlier space race. The Apollo-Soyuz Test Project, a key program and catalyst for Détente, marked the transition to the new age of space collaboration, which continued through the Soviet Interkosmos missions, the Mir-Shuttle dockings of the early 1990s, and on through the International Space Station. Europeans, Americans, and Russians envisioned space collaboration as a way to reconfigure political and international relations.

The shift toward collaboration was a result of a new focus on safety, which displaced the earlier emphasis on risk-taking in the first phase of the space race, when military imperatives often overshadowed peaceful goals. Apollo-Soyuz (ignored by Cold War historians) was thus imagined as a test project for a docking mechanism that would allow a manned-capsule stranded in orbit to dock with another capsule and provide an escape hatch back to earth (it was actually inspired, in part, by the 1969 Hollywood film “Marooned” with Gene Hackman). The focus on engineering for safety grew out of the broader concerns about environmental degradation and nuclear war that in turn reflected a growing sense in the 1970s and 1980s of the dangers associated with excessive risk-taking in politics and engineering. Few historians or social scientists have examined the social construction of safety and its use in engineering and politics.

The book draws on the Russian Academy of Sciences Archives, Nixon and Reagan libraries and National Archives Collections, NASA headquarters library documents, and various memoirs and other published sources in English and Russian.

There has been quite a bit of scholarship on the history of the space race, but collaboration in space has received little attention and has usually been dismissed as a propaganda side show. This book thus fills a critical gap by showing the importance of collaboration in space as an antidote to Cold War hostilities and as an important yet underappreciated episode in the development of science and technology in the twentieth century.
