Nazi Moon base by Darren Tan

Singaporean freelance illustrator Darren Tan visualizing the conspiracy theory of a secret Nazi base on the far side of the Moon.

This alternate history science fiction myth was somewhat started by Rocket Ship Galileo, a 1947 young adult novel by Robert Heinlein, which features three teenagers who travel to the Moon and discover a secret Nazi base. Since then the "secret Nazi Moon base" cultural myth has been used in fiction frequently, including The Man in the High Castle novel (1962) by Philip K. Dick (and its recent TV series adaptation), Iron Sky movie (2012) and Wolfenstein: The New Order video game (2014). We should remember that Von Braun's V-2 rocket was the first man made object reaching outer space in June, 1944, and it was the base for both US and Soviet space programs. So the myth had some logical grounds.
