ISS Evacuation: Astronauts Rush to Soyuz After Leak Nightmare
Disaster drills just became reality on the International Space Station, with crew members scrambling into emergency escape capsules after detecting a critical system failure. Here is what you need to know.
- A sudden drop in cabin pressure triggered emergency protocols, forcing the Expedition 70 crew to seal hatches and abort all non-critical experiments for a full systems check.
- The ISS evacuation standby came after sensors flagged a potentially catastrophic ammonia leak in the cooling loop, which could have led to toxic contamination of the atmosphere within hours.
- Commanders ordered a "bunkering" of the Soyuz MS-24 lifeboat, meaning astronauts donned pressure suits and remained strapped in for nearly 30 minutes as ground teams analyzed the threat level.
- This marks the third time this year hardware failures have forced the crew to consider an actual departure, highlighting growing concerns over the station's aging Russian segment modules.
- Fortunately, the leak was isolated to a non-critical backup loop, and the station was declared safe after a 90-minute "all-clear" period, though the event has sparked urgent calls for accelerated maintenance schedules.
