Calling it music is a stretch, but that’s exactly how the Apollo 10 astronauts described the creepy sounds they heard while swinging around the farside of the moon in May 1969. During the hour they spent alone cut off from communications with Earth, all three commented about a persistent “whistling” sound that lunar module pilot (LMP) likened to “outer-space-type-music”. Once the craft returned to the nearside, the mysterious sounds disappeared. Apollo 10 Farside-of-the-Moon Music.Hands down it was aliens! I wish. Several online stories fan the coals of innuendo and mystery with talk of hidden files and NASA cover-ups narrated to disturbing music. NASA agrees that the files were listed as ‘confidential’ in 1969 at the height of the Space Race, but the Apollo 10 mission transcripts and audio have been publicly available at the National Archives since 1973. Remember, there was no Internet back then. The audio files were only digitized and uploaded for easy access in 2012. Outside of the secretive ’60s, the files have been around a long time.The story originally broke Sunday night in a show on the cable channel Discovery as part of the “NASA’s Unexplained Files” series; you’ll find their youtube video below. As I listen to the sound file, I hear two different tones. One is a loud, low buzz, the other a whooshing sound. My first thought was interference of some sort for the buzzing sound, but the whoosh reminded me of a whistler, a low frequency radio wave generated by lightning produced when energy from lightning travels out into Earth’s magnetic field from one hemisphere to another. Using an appropriate receiver, we can hear whistlers as descending, whistle-like tones lasting up to several seconds.Lightning’s hardly likely on the Moon, and whistlers require a magnetic —> Read More
