On June 5, 2026, NASA’s Crew-12 mission members were directed to take shelter inside the Dragon capsule Freedom due to newly identified leaks in the Russian segment of the International Space Station (ISS). This precautionary measure was taken as the Russian space agency, Roscosmos, initiated extensive repair work to address the leaks.
The leaks, which have been a recurring issue in the Zvezda service module transfer tunnel, known as the PrK, have appeared intermittently over the past six years. The recent discovery of these new leaks prompted Roscosmos to escalate their repair operations, leading to the temporary sheltering of the Crew-12 members, which includes four NASA astronauts and one French astronaut.
Emergency Protocols Activated
NASA spokesperson Bethany Stevens stated that the decision to have the crew assume a heightened safety posture was made out of an abundance of caution. The crew, consisting of four members from the SpaceX Crew-12 mission and NASA astronaut Chris Williams, was instructed to remain inside the Dragon capsule while repairs were underway.
However, around 10:30 a.m. EDT (1430 UTC), the situation shifted. Mission Control informed the crew that the “safe haven” plan was no longer necessary, as the Russian team opted to conduct only measurements that day. This decision allowed the crew to exit the sheltering protocol.
Operational Readiness and Communication
Prior to the sheltering, the crew reported that the Node 2 hatch, part of the Harmony module where Dragon spacecraft dock, was closed at approximately 9:40 a.m. EDT (1340 UTC). They then configured the Dragon spacecraft for communication with ground control, ensuring operational readiness.
Commander Jessica Meir confirmed the successful completion of pre-ingress tasks to Mission Control, expressing gratitude for the team’s quick response. The Dragon capsule is designed to accommodate four crew members, with the capability to add makeshift seating for additional personnel in emergencies, as demonstrated in previous missions.
Looking Ahead
While the specifics regarding the leak rate and the timeline for the discovery of these new leaks remain undisclosed, NASA expressed optimism about collaborating with Roscosmos to effectively address the ongoing issues. The situation underscores the complexities of maintaining safety aboard the ISS as international teams work together in the unique environment of space.
