 What did the Apollo 10 astronauts experience on their legendary transit far beyond Earth contact as they ventured around the dark side of the Moon? Our often illuminated satellite is, to our perspective here on Earth, seemingly rotating on a fixed axis, thus only one side of the Moon has ever been seen from Earth. Additionally, although known as the dark side, it does indeed receive sunlight. In May 1969, Apollo 10 was the fourth manned mission in the United States Apollo program. It was a real-world or real-space operational training mission, an in-depth research and preparation rehearsal in planning of the eventual Moon landing, successfully testing componentry, procedural drills, along with several contingencies for if something went wrong. The mission was completely successful, doing all short of an actual lunar landing. What we find the most enigmatic part of the mission, however, the audio transcripts of what even the astronauts termed alien music was heard by all aboard as they lost contact with Houston as they went behind the Moon. Supporting the theory of an alien transmission are recent discoveries of pulses leaving our planet from several locations, such as Antarctica, Bosnia, Peru, etc. The perplexing purpose for false doors and so forth. Furthermore, due to the sheer mass of rock that would be between the Earth and the far side, if the Moon is receiving any directed transmissions, it's stationing strategically perfect to not only observe us, but avoid detection. The other cause for the music, a personal hypothesis, is that instead of the static we receive upon our television, residually from the big bang, outer of space, especially away from our own statically-generating planet, this noise could, we believe, indeed sound like an eerie melody. Additionally, due to redshift and the Doppler effect, sound would warp through vast space-time travel even from our closest neighbor, Proxima Centauri, yet indeed, if of intelligent and extraterrestrial origin, it would be received as pulse of sound having moments of silence distorted from interstellar travel. However, who knows what advanced technological composition could be possible. The truth is out there, or maybe it's here already.
