This past weekend, the Science Channel released the preview for their newest episode of NASA’s Unexplained Files that told the story of Apollo astronauts who heard weird sounds during their trip around the moon.
The “space music” was heard during the Apollo 10 mission when astronauts Thomas P. Stafford, Gene Cernan, and John Young were on the far side of the moon. As a type of “dress rehearsal” for the first moon landing, the Apollo 10 astronauts went through all of the necessary procedures just short of landing on the lunar surface.
During the mission, Stafford and Cernan went into the lunar lander while Young stayed inside the command module. The two spacecraft separated when the crew was on the far side of the moon and it was at this point in the mission when the astronauts began to hear a weird noise.
Young: Did you hear that whistling sound, too?
Cernan: Yeah. Sounds like – you know, outer-space-type music.
Young: I wonder what it is.-Apollo 10 transcript
The “space music” can be heard at the 2:05 mark in the video below.
