Chief Designer Mishin proposed a two-launch “stopover” scenario for the piloted flight to the moon. This was similar to one of NASA’s earth orbit rendezvous modes to reach the moon. The gist of the plan was, the UR-500K would insert the 7K-L1 into orbit with no crew. Then the R7 derivative Semyorka would launch the 7K-OK carrying two cosmonauts. If everything went well on the two vehicles, they would dock, and the cosmonauts would transfer from the 7K-OK to the 7K-L1 via spacewalk. Then they would set out for the Moon, and, after flying around it, they would return to Earth.
