Kosmos 379 (Russian: Космос 379 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
[edit]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[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]
