In the futuristic world of 1970 the United States Space Force, having established an orbiting space station, readies a reconnaissance mission to survey the Moon for a future base. The assigned mission commander, Major Moore, is annoyed to find that his co-pilot has been replaced with the more famous Colonel Briteis. Unfortunately the two of them have more serious problems to worry about, as the sinister enemies of Freedom have replaced their photographic specialist with a saboteur who is tasked with destroying the space station. When the imposter is uncovered, his desperate struggle with Moore sends the rocket off course, forcing them to land on the moon, thereby establishing America's first lunar base.

Based on a story by Creator/RobertAHeinlein (who shares screenwriting credit with Richard Talmadge) this attempt to portray a bold, exciting future of {{Interplanetary Voyage}}s, female presidents and [[ColonyDrop orbiting H-bombs]] is let down by a mediocre plot and what can only be described as a cringe-inducing portrayal of America's first woman in space; Colonel Briteis (not "[[AccidentalMisnaming bright eyes!]]") a [[GodSaveUsFromTheQueen spoilt, bratty symbol]] of 50's misogyny.

!!The movie has the following tropes:

* BelligerentSexualTension: It's no surprise that Major Moore and Colonel Briteis are married by the end of the movie, as they snark at each other constantly throughout it.
* CompilationMovie: The film is assembled from several episodes of the never-released TV series ''Ring Around the Moon''.
* DirtyCommunists: Well, actually the [[HammerAndSickleRemovedForYourProtection unnamed "enemies of Freedom"]], but we all know who they're meant to be.
* DutchAngle: Used in the space station docking sequence to show that not every object in space approaches on the same plane.
* EvilIsHammy: Averted; the mysterious Mr Roundtree is the most bland DiabolicalMastermind imaginable. Then again he is a spy -- maybe it's part of his cover.
* GravityScrew: People walk along the corridors of the space station upside down past people going the other way due to its variable gravity. They avoid floating off the floor because they were wearing "magnetic shoes". Signs request that you PLEASE DO NOT WALK ON THE WALLS.
* HollywoodScience: Averted. Though it does fall victim to TechnologyMarchesOn, there's a [[MundaneDogmatic serious attempt]] to depict the future of space exploration as seen from the 1950's. A streamlined spaceship only takes them up to the space station, where another craft looking similar to the Apollo Lunar Module (though much larger) takes them the rest of the way. There's also ExpoSpeak explanations of space flight and free fall.
* KinkySpanking: Briteis is threatened with this [[ValuesDissonance by her commanding officer]]. Apparently this was AuthorAppeal for Robert Heinlein.
* PerfectlyArrangedMarriage: Moore is virtually ordered to propose to Briteis, because [[ValuesDissonance the public won't accept the implied hanky-panky of two young unmarried people of the opposite sex working in a close environment together for months]]. Fortunately neither of them are adverse to the idea.
* PunnyName: Miss Prattles, the female journalist. And [[strike:Bright Eyes]] Briteis.
* QuicklyDemotedWoman: Briteis only became the first person in space (thereby being granted the rank of Colonel) because she weighed less than the hero. But Briteis makes up for this at the end of the movie by requesting that Major Moore be promoted to Brigadier General after they're married, so that he will outrank her. What a gal!
** [[VoodooShark Even though the President (thus commander in chief) is also a woman.]]
* RedemptionEqualsDeath: Dr. Wernher dies helping them re-establish contact with Earth.
* RoomDisservice: Evil kidnapping communist bellhops.
* SamusIsAGirl: Colonel Briteis is mentioned several times before her entrance [[PronounTrouble without revealing her gender]]. Likewise the President of the United States.
* ScreamingWoman: Briteis, when the spy is revealed. She does however manage to save the ship by pushing a single button, so she's not completely useless.
* SpaceClothes: Those skullcaps do look silly, even if they do stop your hair floating about in free fall. Briteis' top is also rather tight-fitting, which does [[{{Fanservice}} make up for it]] however.
* SpaceStation: This one looks like a [[FlyingSaucer saucer]] instead of the usual wheel-like structure.
* SpotTheImposter: The fake Dr. Wernher gives himself away because he doesn't follow the World Series. I guess they didn't have nerds in [[TheFifties those days]].
* TheSpymaster: Mr Roundtree
* TwentyMinutesIntoTheFuture: The movie is set in 1970, which meant they were only a year out regarding the moon landing.
* {{Zeerust}}: Finned single-stage-to-orbit ShinyLookingSpaceships, saucer-like space stations with artificial gravity, and cordless phones -- which are your standard 1950's black Bakelite phones with a curly aerial.
