Five of the seven astronauts aboard the International Space Station sheltered inside a SpaceX Dragon capsule Friday following a worsening air leak [1].
The incident highlights the precarious nature of long-term orbital habitation and the critical reliance on docked spacecraft as emergency lifeboats when primary station modules fail.
NASA ordered the crew members, which included two Russian cosmonauts, to take shelter and prepare for a possible evacuation [1, 2]. The leak originated from cracks discovered in the transfer tunnel of the Russian segment [1, 2].
Station officials monitored the situation as the leak worsened, posing a direct safety risk to the crew [1, 2]. The SpaceX Dragon capsule, currently docked to the station, served as the primary safe haven for the five crew members [1, 3].
A NASA spokesperson said the decision to have the astronauts take shelter in the spacecraft was made “out of an abundance of caution” [4].
While two crew members remained outside the capsule, the majority of the team spent June 5, 2026 [2], preparing for a rapid departure from the station if the structural integrity of the Russian module continued to decline [1, 2].
The Russian segment is integral to the station's propulsion and power systems, making any structural failure in its tunnels a high-priority emergency for all international partners [1, 2].

This event underscores the aging infrastructure of the International Space Station, where material fatigue in the Russian segment can now trigger full-scale evacuation protocols. The use of the SpaceX Dragon as a shelter demonstrates the shift toward commercial spacecraft providing essential safety redundancies for international crews.
