The American Apollo spacecraft as seen in earth orbit from the Soviet Soyuz spacecraft during the joint U.S.-USSR Apollo Soyuz Test Project mission. The Command/Service Module and Docking Module are contrasted against a black-sky background. Light reflected in the camera streaks the image. Note the docking mechanism and docking target on the Docking Module. On the left the bell-shaped engine nozzle of the service propulsion system protrudes from the rear of the Service Module.
