Beginnings
Vostok and Mercury
Voskhod and Gemini
Soyuz and Apollo
Meanwhile, the Soyuz program called for the development of a three-stage expendable launch rocket and a spacecraft that consisted of three modules (orbital, descent, and an instrumentation and propulsion). In time, many iterations of the Soyuz craft were created, including the Soyuz 7K-L1 (Zond) capsule. Paired with the N1 rocket, this craft was the backbone of the Soviet manned lunar program.
