Apollo-Soyuz: Cold War Collaboration
On July 17, 1975, the Apollo and Soyuz spacecrafts docked together in space during the first joint U.S.-Soviet space mission. Cosmonauts Aleksey Leonov and Valeri Kubasov and astronauts Thomas Stafford, Vance Brand, and Donald Slayton conducted joint scientific experiments, exchanged gifts, and spoke in each other’s languages.
This mission was seen as an opportunity not only to cooperate in space but also to strengthen U.S.-Soviet cooperation in general.
President Ford and Soviet General Secretary Brezhnev both called to congratulate the crews after the docking.
