The Apollo-Soyuz Test Project in 1975 marked the first time that the U.S. and the Soviet Union cooperated in a manned space mission. American and Russian engineers developed a docking module to link the spacecraft. Control centers in Moscow and Houston exchanged tracking data and shared communications. After the two spacecraft launched from Kazakhstan and Florida to rendezvous in orbit, the crews visited each other's spacecraft, shared meals, and worked on tasks during several days together in space. The project is discussed in the NASA report, by historians Edward Clinton Ezell and Linda Neuman Ezell, available in this web site, in PDF "The Partnership: A History of the Apollo-Soyuz Test Project".
