L1 Complex 1961

On 10 March 1962 Korolev approved the technical project "Complex docking of spacecraft in earth orbit - Soyuz". This contained the original Soyuz L1 circumlunar design. The Vostok-Zh could be used on another mission to assemble a 15 metric ton orbital station with the mission of observing the earth. It would consist of three separately-launched blocks: a ZhO living section, BAA scientific apparatus block, and the Soyuz spacecraft itself. This closely resembled Sever, another contemporary study project at OKB-1.

Mass: 13,500 kg (29,700 lb).

• 1962 March 10 - Soyuz Technical Project approved. -
  Korolev approved the technical project 'Complex docking of spacecraft in earth orbit - Soyuz'. The Soyuz would first be tested using multiple launches of an R-7 derived rocket. In this concept a large spacecraft was assembled in earth orbit by a Vostok-Zh (or Vostok-7) manoeuvrable manned satellite, piloted by a 'cosmonaut assemblyman'. Following completion of assembly, the Vostok would return to earth. The assembled circumlunar craft would put the L1, with a crew of one to three, on a circumlunar trajectory. The Vostok-Zh could be used on another mission to assemble a 15 tonne OS orbital station with the mission of observing the earth.
