Kosmos 379 (Template:Langx meaning "Cosmos 379"), also known as T2K No.1, was an uncrewed test of the LK (the Soviet counterpart of the Apollo Lunar Module) in Earth orbit.
Mission
Earth orbit simulated propulsion system operations of a nominal lunar landing mission. Kosmos 379 entered a 192 to 232 km low Earth orbit. After three days it fired its motor to simulate hover and touchdown on the moon, in imitation of a descent to the lunar surface after separation of the Blok D lunar crasher[<span title="Script error: No such module "decodeEncode".">clarification needed] propulsion module. The engine firing changed its orbit from 192 km × 233 km to 196 km × 1206 km (delta-V = 263 m/s).
After a simulated stay on the Moon, it increased its speed by 1.518 km/s, simulating ascent to lunar orbit making the final apogee 14,035 km. These main maneuvers were followed by a series of small adjustments simulating rendezvous and docking with the Soyuz 7K-L3. The LK lander tested out without major problems and decayed from orbit on September 21, 1983.[1]
