Apollo Soyuz Test Project: Bridging the Divide and Handshake That Changed History

How does a single handshake in orbit change the course of history? On July 17, 1975, two spacecraft representing the world's competing superpowers locked together in Earth orbit. The photograph of American commander Thomas Stafford and Soviet commander Alexei Leonov clasping hands in the cramped docking module remains one of the most iconic images of space exploration. However, the profound story behind that image-the years of intense diplomatic negotiation, engineering ingenuity, cultural exchange, and personal commitment that made it possible-has rarely been explored in such comprehensive detail. This book provides a history of the Apollo-Soyuz Test Project (ASTP). Born out of the détente diplomacy of the early 1970s, ASTP was simultaneously a monumental diplomatic gesture and an unprecedented technological experiment. The mission required three years of extraordinary technical cooperation between NASA and the Soviet Academy of Sciences. Together, rival engineers were forced to overcome a daunting catalog of incompatibilities between the Apollo and Soyuz spacecraft to make the joint flight a reality. From the origins of the Cold War space race to the dramatic American reentry incident, this comprehensive history chronicles the end of the Apollo era and the birth of a new age of international cooperation.
