You've probably seen the headline. It pops up in late-night Reddit threads and creepy YouTube "true story" compilations every few months. Someone claims that a secret recording exists where an astronaut screams for 9 minutes straight while drifting into the void. It’s the kind of thing that makes your skin crawl.
Space is silent. We know this. Vacuum doesn't carry sound waves. But the idea of a person trapped inside a pressurized suit, losing their mind as they drift away from the ISS or a lunar module, hits a primal nerve. It’s terrifying. It's also, if we’re being honest, mostly a product of internet creepypasta and a misunderstanding of how space radio works.
Where Did the Legend of the 9-Minute Scream Come From?
People love a good conspiracy. Usually, when people search for "astronaut screams for 9 minutes," they are looking for the "Lost Cosmonauts" theory. This dates back to the 1960s. Two Italian brothers, Achille and Giovanni Judica-Cordiglia, claimed to have intercepted Soviet radio transmissions at their homemade listening station, Torre Bert.
They recorded some weird stuff.
One recording supposedly features a woman—often called the "Siberian Lady"—screaming as her craft burns up upon re-entry. Another is a series of rhythmic gasps and heartbeats that supposedly fade into silence. These recordings are chilling. They are also highly disputed by historians and space experts like James Oberg. The Soviet Union was secretive, sure, but the physics and timing of these supposed "lost" missions often don't align with actual launch windows or orbital mechanics.
The Power of Audio pareidolia
Our brains are wired to find patterns. If you listen to static long enough, you'll hear a voice. If you listen to a distorted radio transmission of a cooling pump or a pressurized valve venting, and someone tells you it's an astronaut screams for 9 minutes, your brain will make it fit.
Space is noisy in a way people don't expect. Not "sound" noisy, but electromagnetically noisy. Solar flares, planetary magnetospheres, and even the electronics inside a suit create a cacophony of pings, whirs, and static. When these are compressed through low-bandwidth radio links, they sound haunting. They sound human.

The Reality of Silence in a Spacesuit
Let's get into the technical side of why a 9-minute scream is actually a logistical nightmare.
If an astronaut were actually in trouble, the "screaming" wouldn't be the primary sound. You’d hear the Life Support System (LSS) working overtime. You’d hear the frantic clicking of switches. Modern suits, like the Extravehicular Mobility Unit (EMU), have incredibly sensitive microphones positioned right near the mouth. If someone screamed for nine minutes, the audio clipping would be so severe that it would likely just sound like a wall of white noise.
Also, have you ever tried to scream for nine minutes? Honestly, go ahead and try it. You'll pass out.
The physiological toll of sustained screaming is massive. It spikes CO2 levels in the blood. In a closed-loop oxygen system, the scrubbers—usually lithium hydroxide canisters—are designed to handle a specific metabolic rate. A 9-minute panic attack of that magnitude would likely overwhelm the system’s ability to clear CO2, leading to hypercapnia long before the nine minutes were up. You'd be unconscious or dead before the recording finished.
Famous "Creepy" Sounds That Actually Happened
While the astronaut screams for 9 minutes story is almost certainly a myth, there are real recordings that are just as unsettling.
- The Apollo 10 "Music": When the Apollo 10 crew went behind the dark side of the Moon, they were cut off from Earth. Suddenly, they heard a "whistling" sound in their headsets. Gene Cernan and John Young actually discussed whether they should tell NASA. They called it "space-type music."
- The Mystery Knocking: Chinese astronaut Yang Liwei reported hearing a sound like a "wooden hammer hitting an iron bucket" during his 2003 mission. He looked out the porthole, but nothing was there. No one was knocking.
- The Saturn Radio Waves: NASA’s Cassini spacecraft recorded radio emissions from Saturn that, when converted to audio, sound like a 1950s sci-fi horror movie soundtrack.
The Apollo 10 "music" was later explained as radio interference between the Lunar Module and the Command Module’s VHF radios. The "knocking" Yang Liwei heard? Likely the result of the spacecraft's skin expanding and contracting due to extreme temperature changes between sun and shadow.

Why This Urban Legend Persists
Fear of the unknown. That’s the bottom line.
Space is the ultimate "unknown." It is the most hostile environment humans have ever tried to inhabit. When we hear stories about an astronaut screams for 9 minutes, we aren't just engaging with a conspiracy theory. We are engaging with our own fear of isolation.
There's a specific kind of loneliness in space. In 1971, the crew of Soyuz 11 died during re-entry because a vent valve opened prematurely. They weren't screaming; they were trying to fix it. They were found perfectly still in their seats, looking as if they were asleep. That reality—the quiet, mechanical failure of a tiny valve—is arguably much scarier than a dramatic 9-minute scream. But it doesn't make for a catchy creepypasta.
Breaking Down the Viral Claims
If you encounter a video or "leak" claiming to be this recording, look for these red flags:
- Too much reverb: Space suits are cramped, padded environments. Audio should sound "dry" and close, not like it's in a cathedral.
- Continuous breath: Human lungs need to inhale. If the "scream" doesn't have gasps for air, it's a synthesized loop.
- Perfect English/Russian: Distorted radio from 200 miles up is rarely crystal clear. If you can understand every word of a "secret" transmission, it's likely a foley job.
How NASA and Roscosmos Handle Traumatic Audio
Both NASA and the Russian space agency have protocols for "black box" audio. If a tragedy occurs, the audio is classified—not to hide aliens or "screams," but out of respect for the families.

Take the Challenger or Columbia disasters. We have the transcripts. We know what was said. In the case of Challenger, the last recorded words were pilot Michael Smith saying, "Uh-oh." It wasn't 9 minutes of screaming. It was a fraction of a second of realization. That's the reality of aerospace accidents: they happen fast.
Moving Past the Myth
The astronaut screams for 9 minutes trope is a fascinating look at how we project our Earthly fears into the cosmos. It’s a campfire story for the digital age. But when you look at the actual history of space exploration, the real stories are much more complex. They involve incredible bravery, terrifying technical failures, and the eerie, beautiful sounds of planetary physics.
If you’re interested in the actual sounds of the universe, you should check out the NASA "Symphonies of the Planets" recordings. They aren't screams. They are the electromagnetic vibrations of Jupiter’s rings and the solar wind hitting the Earth’s magnetosphere.
Actionable Next Steps for Space Enthusiasts
If you want to dive deeper into what actually happens during space emergencies, stop looking at "top 10 scary facts" videos. Start here:
- Read the transcripts: The Johnson Space Center maintains a massive archive of mission transcripts. You can read exactly what the Apollo and Gemini crews said during their most harrowing moments.
- Learn about "The Hum": Research the "Space Shuttles' Cabin Fan Hum," which was a constant, low-level drone that astronauts had to live with for weeks. It’s a great example of how "sound" exists in space (via conduction through the ship's frame).
- Check out the Judica-Cordiglia archives: If you want to see where the "lost cosmonaut" myth started, look at the original 1960s reports from the Italian brothers. Just keep your skeptical hat on.
- Follow NASA's SoundCloud: They regularly upload actual audio from Mars rovers (like Perseverance) and space probes. It’s the best way to train your ear to hear the difference between a mechanical "thump" and a "scream."
The universe is plenty weird on its own. We don't need to invent 9-minute screams to make it haunting.
