July 15, 1975: Apollo-Soyuz Test Project launched

American and Soviet crews were launched today in 1975 for the first handshakes in space between the two superpowers as part of the Apollo-Soyuz Test Project. The Soviet Soyuz with cosmonauts Aleksey Leonov and Valeriy Kubasov was launched from the Baikonur Cosmodrome about seven hours before the American Apollo-Saturn 1B with Tom Stafford, Vance Brand and Deke Slayton lifted off from Kennedy Space Center.
