Soyuz!

Photos from the Kennedy Space Center Visitor Complex of the full-size replica of the Russian Soyuz spacecraft that docked in orbit with an Apollo spacecraft in July 1975 during the Apollo-Soyuz Test Project promoting goodwill between the American and Soviet crews. An updated version of this same vehicle is used today to ferry crews back and forth from the International Space Station (ISS). First flown in April 1967, the Soyuz spacecraft has had remarkable success over the decades proving to be a tough and resourceful vehicle albeit with a few unfortunate cosmonaut casualties. Note this Soyuz shows its 1975 livery as a spacecraft of the Union of Soviet Socialist Republics.

The petals at the front of the Soyuz are part of the docking mechanism that interlock with the petals on the Apollo docking module used in the Apollo-Soyuz Test Project. An unmanned version of the Soyuz spacecraft, called Progress, is used to ferry supplies to the ISS.

Then as now, the Soyuz has three major parts, the orbital module at front that provides living and storage space while in orbit, the descent module from where the vehicle is controlled and is the only part to return to Earth carrying the crew, and the Instrument Assembly, or Service, Module provides the Soyuz with, among other things, propulsion and power from the two solar arrays sticking out on either side like wings.
