Music on the Moon?

In the audio recordings from the Apollo 10 mission (which you can hear in this video from Space.com), astronaut Gene Cernan(who was piloting the lunar module) asks John Young (who was piloting the command module) if he hears "that whistling sound?" It is Cernan who calls it "music" and says it "even sounds outer-spacey." Later, the two men ask Tom Stafford (who is in the lunar module with Cernan) if he hears it, too. They agree that it's "really weird," and Young says, "We're going to have to find out about that. Nobody will believe us." [Lunar Legacy: 45 Apollo Moon Mission Photos]

Apollo 10, launched in May of 1969, paved the way for Apollo 11, launched in July of that same year, to put two humans on the lunar surface. The Apollo 10 astronauts flew to the moon in a command module, and two of the crewmembers also took a ride in the lunar module, dropping down to less than ten miles above the moon's surface. The whistling sound, it turned out, was nothing more than interference between the VHF radios on the two different vehicles.


Apollo 11 astronaut Michael Collins wrote in his book, "Carrying the Fire," that NASA technicians warned him about the whistling. Multiple publications have pulled the key passage from the book, in which Collins even says, "Had I not been warned about it, it would have scared the hell out of me." Collins' book was published in 1974.
