An artist's concept illustrating an Apollo-type spacecraft (left) about to dock with a Soviet Soyuz-type spacecraft. A recent agreement between the United States (USA) and the Union of Soviet Socialist Republic (USSR) provides for the docking in space of the Soyuz and Apollo-type spacecraft in Earth orbit in 1975. The joint space venture is called the Apollo-Soyuz Test Project (ASTP).
