Astronauts aboard Apollo 10 may have encountered more than they expected when they journeyed to the far side of the moon back in May 1969. In fact, it sounds as if the three men weren’t alone up there.
Apollo 10 was designed to support another mission that would happen two months later. Its astronauts, Tom Stafford, John Young and Eugene Cernan had entered the moon’s lunar orbit as it managed to get within 5,000 feet of its surface. The unexplainable happened during the time the astronauts were journeying along the far side of the moon.
At this stage of the journey, all contact with NASA would cease and Stafford, Young and Cernan were left on their own. This lack of communications with NASA would last for an hour, and it was in this hour the men said they heard a strange noise.
When the astronauts first came home, all recordings were transcribed, archived and classified. This was the protocol in Mission Control. But in 2008, a startling discovery was revealed in the tapes. The astronauts can be heard remarking, “The music even sounds outer-spacey, doesn’t it.” They clearly could not explain where it was coming from or what it was. It was described as a whistling sound; they said it sounded like “Whoooooooo…” And the so-called music continued almost throughout the hour the men were without communication from NASA.
According to Fox News, there are technicians who said that the “music” heard by the astronauts may have been due to interference from VHF radios on the command and lunar modules as it interacted with each other. Nonetheless, Apollo 15 Command Module Pilot Al Worden that the three astronauts can very well distinguish that kind of noise from the stranger “music” all three of them had heard.
