Kosmos 382 was a Soviet Soyuz 7K-L1E modification of a Soyuz 7K-L1 "Zond" spacecraft and was successfully test launched into Low Earth Orbit on a Proton rocket designated as (Soyuz 7K-L1E No.2) on December 2, 1970.

The main purpose of the mission was to test the N1/L3 spacecraft's Block D lunar orbit insertion/descent stage by simulating the lunar orbit insertion burn, the lunar orbit circularization burn and the final lunar descent burn.

The Block D stage was fitted with cameras in the tanks to monitor the fuel and oxidizer behaviour in weightlessness and during acceleration.

[1] Kosmos-382 also carried other experiments, including a prototype environmental control subsystem named "Rosa" for producing potable water from atmospheric condensate exhaled by cosmonauts onboard Soviet crewed spacecraft.
