Silent threat has emerged 250 miles above Earth, and 5 astronauts just took shelter from it. NASA ordered 4 SpaceX Crew-12 members and astronaut Chris Williams to evacuate their usual posts on the International Space Station and board the docked Dragon spacecraft. The reason was not a collision warning or a solar flare. It was a leak. Air has been escaping from the Russian Zvezda service module's transfer tunnel, known as PrK, an area plagued by cracks for years. Roscosmos attempted an extensive repair operation, and NASA chose to play it safe. The leak rate had been relatively minor for months, but it worsened dramatically last Monday. What was once half a kilogram of lost air per day climbed to nearly a full kilogram. That acceleration triggered the evacuation protocol. The astronauts donned their suits and remained inside Dragon while Russian engineers worked. The order lasted roughly two hours before NASA gave the all clear and the crew returned to normal station operations. This event is not a crisis, but it is a warning. The Zvezda module has been in orbit since 2000. Its aging structure now shows fractures that cannot be permanently sealed with patchwork repairs. Each new crack raises the same unsettling question: How much longer can the oldest parts of the station hold? The ISS is scheduled for retirement in 2030. Until then, every alarm, every leak, and every unscheduled shelter drill will serve as a reminder that even humanity's most advanced outpost is slowly coming apart at the seams. #wtf #fblifestyle #ISS #SpaceStation #NASA
