Cosmic Voyage or The Space Voyage (Russian: Космический рейс, romanized: Kosmicheskiy reys: Fantasticheskaya novella) is a 1936 Soviet science fiction film produced by Mosfilm. It was one of the earliest films to represent a realistic spaceflight, including weightlessness.
Kosmicheskiy reys: Fantasticheskaya novella was initially conceived in 1924 by Russian filmmaker Vasili Zhuravlov, but it was not pursued for production until 1932, when Komsomol (the Communist Union of Youth) recommended the creation of film that would spur an interest in space studies. Zhuravlov consulted with Konstantin Tsiolkovsky, the noted aeronautical theorist and rocket science engineer, on the screenplay. Tsiolkovsky died shortly after the film was completed.
Two spaceships in the film were named after the Soviet leaders Joseph Stalin and Kliment Voroshilov. The film’s cosmonauts enter liquid-filled chambers to buffer the impact of takeoff and landing, and they communicate their landing to the Earth by spelling out “CCCP” (the Russian-language acronym for “USSR”) with reflective substances spread across the lunar surface.
