SORRY Pink Floyd, real sounds from the dark side of the moon are way trippier.

A crew of astronauts on Apollo 10, three months before Neil Armstrong’s famous landing, captured “music” while orbiting the backside of the moon — when communication is temporarily cut-off with Earth — according to newly released sound recordings of the 1969 mission.

The mission was taking one of its 31 turns around the lunar body when whizzing and whistling sounds unlike anything the astronauts had ever heard filled the spacecraft.

“You hear that? That whistling sound?” asks one of the astronauts before mimicking the eerie noise: “Whooooooooo!”

“That music even sounds outerspacy doesn’t it?” he says.

“That sure is weird music,” says his companion.

The team of three, Thomas P. Strafford, John W. Young and Eugene A. Cernan, continued to comment on the strange noise for the next hour before the ship rounded to the Earth-facing side of the moon.

Retired Apollo 15 astronaut Al Worden said if he had been there, cut off from communication with NASA headquarters, he would have freaked out.

“If I were to hear something back there, the first thing probably, it would freak me out,” Worden says in the preview of the Science Channel series NASA’s Unexplained Files.”

The recording had been locked away for nearly 40 years until reams of data from the Apollo missions was declassified in 2008, and now shared publicly through the documentary TV series. It starts a third season on Tuesday.

In preview, the experts don’t explain the source of the space music, which predated Pink Floyd’s album by four years.
