Corrected entry: In space the space shuttles make a jet sound even though there is no sound in space. Even the ones leaving from the space station make this noise and although there might be some rumbling to be heard inside the space station, there wouldn't be anything else since there is no atmosphere for sound to travel through.

Correction: Yes, technically a mistake but the sounds are added for our benefit so we know what's going on. It would be pretty boring if all space scenes in all movies were required to be in silence just to be factually accurate.
