Russian manned lunar orbiter. Modification of Soyuz circumlunar configuration used in propulsion tests of the Block D stage. Technology satellite, Russia. Launched 1969 - 1970. Used the Blok-D bus.
The L1E provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions. Probably included a dummy descent module (not recovered).

Decay Date: 1969-11-16 .
Attempted test flight of Block D upper stage in N1 lunar crasher configuration. Payload was a modified Soyuz 7K-L1 circumlunar spacecraft, which provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions. Mission flown successfully over a year later as Cosmos 382.

Duration: 8,549.30 days. USAF Sat Cat: 4786 . COSPAR: 1970-103A. Apogee: 5,269 km (3,273 mi). Perigee: 2,384 km (1,481 mi). Inclination: 55.90 deg. Period: 171.00 min.
Test of Block D upper stage in its N1 lunar crasher configuration in earth orbit. The three maneuvers simulated the lunar orbit insertion burn; the lunar orbit circularization burn; and the descent burn to bring the LK lunar lander just over the surface. Payload was a modified Soyuz 7K-L1 circumlunar spacecraft, which provided guidance to the Block D and was equipped with television cameras that viewed the behavior of the Block D stage propellants under zero-G conditions.
