I watched this because it is written, in some sense, by Robert A. Heinlein.
It does look very 50s schlockfest-like, I must admit.
It's view of how female military officers would dress (that is, what their version of the uniform would look like, and how they would behave) fits in quite well with Heinlein's novels and with 50s expectations.
IOW, the uniform looks nothing like the one the men are wearing, and the officer herself is basically a spoiled brat.
So, if nothing else, this film records attitudes towards women prevalent in the 50s which are now a bit ... undesirable. To say the least.
The film is short; it would be even shorter except that they took the time to show us exactly how the commie agent was infiltrated onto the team and what his orders were.
The budget was low, the actors are unknown; however, I think they did a good job with their roles. And what's an extra that looks like a mannequin among friends?
It manages a credible job at portraying space travel. Keep in mind that, in 1953, nobody actually /knew/, from experience, what it was like. The theory, however, used to make the film was clearly sound.
