|LOK reaction control - The upper half of this item is the ODOP (Orientation and docking engine section) of the LOK, mounted at the top of the orbital module. The cone at top was had grapples for snagging the hexagonal grid of the large disk on top of the LK. Propellants for the orientation and maneuvering engines were in the tanks in this section. The bottom half of this item is similar to a test installation used on the Soyuz 7K-L1S destroyed in the several N1 launches.|

Command number 655-268 was issued by Central Committee of Communist Party. Chelomei was to develop the LK-1 for the manned lunar flyby while Korolev was to develop the N1-L3 for the manned lunar landing. First launch of the N1 was to be by the first quarter 1966, with manned lunar landings in 1967 to 1968. Reprioritization led to work being stopped on Korolev's Zvezda 6 man orbiting weapons platform by mid-1965, after a huge mockup had been built. Chelomei as usual issued the advanced project for the LK-1 on the same day. The decree also ordered development of the three-stage version of his Proton UR-500 to boost the LK-1 around the moon.

Soviet government approves plan to land cosmonaut on moon by end 1968. N-1 test plan approved, envisioning third quarter 1967 as beginning of flight hardware construction. Fall-back project would be manned circumlunar mission. First manned L1 mission imagined as early as June 1967. First N1 launch by March 1968.

Superbooster failure of N1 serial number 6L. This was a substantially improved vehicle, incorporating filters in the propellant lines to prevent any foreign objects from getting into the pumps. The shape of the tail of the booster was modified, and ventilation and refrigeration systems were added to keep the engine compartment cool. It was painted white overall to reduce temperatures while sitting on the pad. After liftoff and ascent, an axial rotation was introduced by gas dynamics interactions of the thirty engines with the air slipstream. The launch vehicle developed a roll beyond the capability of the control system to compensate. and began to break up as it went through Max Q. Control was lost at 50.2 seconds into the flight and it was destroyed by range safety a second later. The engines functioned well and did not shut down up to the point of vehicle destruction. No functional payload was carried. It has been stated that this launch did not have a working launch escape system.
