The
Soyuz 7K-LOK, or simply
LOK ( meaning "Lunar Orbital Craft") was a
Soviet manned spacecraft designed to launch men from Earth to circle the moon and developed in parallel to the
7K-L1. The LOK would carry two cosmonauts into orbit around the Moon, acting as "mother" spacecraft for the
LK Lander, which would land one member of the crew to the surface. It was part of the
N1-L3 programme which also included the LK lander and the
N1 rocket.
