News Analysis — AI Analysis
Original analysis generated by News Analysis. This is our own commentary on the story, not the publisher's article text.
The article recounts the tragic death of the reserve crew members aboard Soyuz 11 in 1971. The cosmonauts died just minutes before landing due to a catastrophic depressurization event. This occurred when an explosive bolt jarred open a pressure equalization valve prematurely, causing the cabin air to escape into the vacuum of space.
Key points
- The Soyuz 11 reserve crew members perished shortly before their planned re-entry and landing on Earth.
- The tragedy was caused by a premature opening of a pressure equalization valve due to an explosive bolt's shock.
- This rapid depressurization led to the swift loss of cabin air, causing the cosmonauts to lose consciousness within minutes.
- The crew attempted to manually close the valve but were unable to prevent the catastrophic leak.
- At the time, this mission represented a record-setting stay in space for the reserve astronauts.
Claims assessed
- VerifiableThe cosmonauts died because an explosive bolt jarred open a pressure equalization valve that was meant to open only during parachute descent.
- VerifiableThe rapid depressurization caused the air's moisture to condense, creating a freezing fog inside the capsule.
- VerifiableThe cosmonauts lost consciousness and died within two minutes due to the pressure drop, as they were not wearing pressure suits.
Missing context
The article mentions that the original reason for the reserve crew taking over was due to concerns about Valery Kubasov having tuberculosis, but it does not explicitly state when or how those medical concerns were definitively resolved after the mission's completion.
