Gog is a 1954 film directed by Herbert L. Strock. It is notable for having been shot in colour, widescreen and 3-D. It is the third episode in Ivan Tors' Office of Scientific Investigation (OSI) trilogy, following The Magnetic Monster and Riders to the Stars, the later of which we've already looked at.
Here are some familiar spacesuits we've seen before in quite a number of other genre films.
