Moon music recorded on the dark side of Earth's celestial satellite by Apollo 10 astronauts in 1969 has been newly declassified, and will be featured in the upcoming Science Channel series "NASA’s Unexplained Files."
Thomas Stafford, John Young, and Eugene Cernan were the second set of astronauts to ever orbit the moon, and when they were on the dark side, they began to hear strange sounds over their headsets,
CNN reported.
"Did you hear that whistling sound, too?" asks one of the men on the newly released audio.
"Yes. Sounds like — you know, outer-space-type music," another man responds.
"I wonder what it is," says the first man.
In interviews for the news TV show, the men, now much older, explained that they weren't sure they should mention the sounds they were hearing to their superiors and colleagues, for fear they would be taken for crazy.
On the show, a NASA technician said that the so-called "music" heard by the astronauts resulted when "radios in the two spacecraft [the lunar module and the command module] were interfering with each other."
This explanation, however, is in turn disputed by Apollo 15 astronaut Al Worden.
"If I were to hear something back there . . . it would freak me out," said Worden. "The Apollo 10 crew was very used to the kind of noise that they should be hearing. Logic tells me that if there was something recorded on there, then there was something there."
The new TV show airs Tuesday.
The New York Post reported that the moon music was recorded four years before Pink Floyd’s "Dark Side of the Moon," the band’s eighth studio album.
