I was looking at a Roscosmos news item Russian monitoring tools track the stage of the rocket that launched the module of the Chinese station about the reentering Long March 5B
This situation will not affect the territory of the Russian Federation. (all google translations)
but then poked around the same website and found the following images relating to Fidel Castro and the Cuban cosmonaut Arnaldo Tamayo Méndez.
These three images caught my interest, especially the one with what looks like it might be Fidel Castro sitting in an early spacecraft.
Question: Was Fidel Castro ever in a Soviet spacecraft? If so, which one? Is this it? When? Was he in or did he see any others?
