On this date in 1975, the Apollo-Soyuz Test Project had a N.A.S.A. Apollo spaceship dock with a Russian Soyuz spacecraft in Earth orbit. Two Cold War rivals ended their ‘space race’ and proved that high-flying, high-tech cooperation was possible.
The mission included separate and cooperative scientific experiments and provided useful experience for future joint work such as the Shuttle–Mir Program and the International Space Station.
