English: S75-22410 (March 1975) --- These five men compose the two prime crews of the first-ever two-nation cooperative space mission, known in the US as the Apollo-Soyuz Test Project (ASTP) and in the Soviet Union as the Soyuz-Apollo Experimental Flight (Russian: Экспериментальный полёт Союз-Аполлон, Eksperimantalniy polyot Soyuz-Apollon). This was a docking mission in Earth orbit scheduled for July 1975. They are astronaut Thomas P. Stafford (standing on left), commander of the American crew; cosmonaut Aleksey A. Leonov (standing on right), commander of the Soviet crew; astronaut Donald K. Slayton (seated on left), docking module pilot of the American crew; astronaut Vance D. Brand (seated center), command module pilot of the American crew; and cosmonaut Valeriy N. Kubasov (seated on right), engineer on the Soviet crew. The crew members wear the same mission patch, but oriented to reflect "Soyuz-Apollo" or "Apollo-Soyuz", as the program was called in their respective countries.
