First Spaceship On Venus (1960) (7x5)

:

The label said the film takes place in the future year of 1985, when scientists discover an ancient alien artefact buried deep beneath the earth, and decide to send a team of astronauts to the source. That sounds a lot like 2001: A Space Odyssey to me and, to confirm my suspicions, it's based on a novel by Stanislaw Lem, who gave us the most famous of all Soviet science fiction stories, Solaris, so it must be...long.
