A view of the Soviet Soyuz spacecraft in Earth orbit, photographed from the American Apollo spacecraft during the joint U.S.-USSR Apollo Soyuz Test Project (ASTP) docking in Earth orbit mission. The Soyuz is contrasted against a white cloud background in this overhead view. The three major components of the Soyuz are the spherical-shaped Orbital Module, the bell-shaped Descent vehicle, and the cylindrical-shaped Instrument Assembly Module from which two solar panels protrude.
