Apollo-Soyuz 1975 Phone Case

Apollo–Soyuz was the first crewed international space mission, carried out jointly by the United States and the Soviet Union in July 1975. Millions of people around the world watched on television as a United States Apollo spacecraft docked with a Soviet Soyuz capsule. The project, and its handshake in space, was a symbol of détente between the two superpowers during the Cold War. The mission was officially known as the Apollo–Soyuz Test Project (ASTP). The three American astronauts and two Soviet cosmonauts performed both joint and separate experiments. The pre-flight work provided useful engineering experience for later joint American–Russian space flights, such as the Shuttle–Mir program and the International Space Station.
