The North Korean cosmonaut is listening to music in his capsule when the batteries in his tape recorder start to die. A close-up of the cassette shows the tape hub visible through a transparent shell. The next shot of the recorder shows that the tape in it is a different design, with a label that covers most of the face of it.
The North Korean cosmonaut has a photo of his wife stuck with a piece of red tape to the instrument panel of his capsule. When he removes it to look at it more closely, the view switches back and forth between his perspective looking at the photo and a view of his face with the back of it showing. From the front the tape is there, but from the back it is missing.
