First Day Issue Cover - Apollo Soyuz Space Mission - Americana

First Day of Issue featuring Apollo Soyuz Space Mission.

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; Russian: Экспериментальный полёт «Союз» – «Аполлон» (ЭПАС), romanized: Eksperimentalniy polyot Soyuz–Apollon (EPAS), lit. 'Experimental flight Soyuz-Apollo', and commonly referred to in the Soviet Union as Soyuz–Apollo; the Soviets officially designated the mission as Soyuz 19). The unnumbered American vehicle was left over from the canceled Apollo missions, and was the last Apollo module to fly.

The three American astronauts, Thomas P. Stafford, Vance D. Brand, and Deke Slayton, and two Soviet cosmonauts, Alexei Leonov and Valeri Kubasov, performed both joint and separate scientific experiments, including an arranged eclipse of the Sun by the Apollo module to allow instruments on the Soyuz to take photographs of the solar corona. 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.
