Marooned

There is no musical score for this film. Instead, each spacecraft has its own ambient soundtrack when it is shown in space. The Apollo shots feature a low hum; the XRV, a hollow ringing; the Nimbus Weather Satellite, a rapid series of beeps ascending in pitch; and the Russian Voshkhod, a constant pitch series of beeps. The only exceptions to this is are a very slight, muted bit of music played under the Apollo ambient soundtrack during Pruett's final EVA, and a single tone (with some ambient effects that could be called music) during the opening credits.

The Mediterranean coastline as seen from orbit on several occasions barely resembles the correct geography. Spain is distorted and the Strait of Gibraltar is almost unrecognisable.

The version titled "Space Travelers" is the one spoofed by Mystery Science Theater 3000. In this version, the scene where Celia Pruett learns of her husband's death is accompanied by a truly AWFUL electronic score (it sounds literally like random keys played on a toy synthesizer, something MST3K made note of). The original version has no music during this scene (and almost no other music; a muted, very low-key score can be heard when Pruett leaves the ship to "fix" it).
