Die Saga um das Luftleck der Internationalen Raumstation nahm am Freitag eine besorgniserregende Wendung | „Wir freuen uns darauf, mit Roscosmos an einem gemeinsamen Ansatz zur Behebung der Lecks zu arbeiten.“

>Five of the seven crew members on the International Space Station briefly sought refuge inside a SpaceX return capsule Friday morning as two Russian cosmonauts worked on an air leak on the other end of the complex.
>NASA ordered US astronauts Jessica Meir and Jack Hathaway, French astronaut Sophie Adenot, and Russian cosmonaut Andrey Fedyaev into SpaceX’s Crew Dragon Freedom spacecraft around 9 am EST (14:00 UTC) on Friday. The foursome launched aboard the SpaceX crew capsule on the Crew-12 mission in February, and the ship serves as their lifeboat until the crew’s scheduled return to Earth in September.
>NASA astronaut Chris Williams, who flew to the station in a Russian Soyuz ferry ship, joined the Crew-12 astronauts inside the Dragon spacecraft.
>“All USOS (US Orbital Segment) crew members need to execute … Emergency Procedure 3.4: Crew Dragon, establish Safe Haven,” NASA mission control radioed to the station crew around 9 am. “If we need (you) to suit up, we will do that once we’re inside the Dragon.”
>A short time later, a NASA spokesperson posted a statement on X attributing the shelter order to a repair on persistent air leaks on the Russian segment of the space station. For more than half a decade, engineers from Roscosmos and NASA have tracked the leak rate from a transfer tunnel on the back end of Russia’s Zvezda Service Module. The tunnel, known by the Russian acronym PrK, leads to a docking port for Progress resupply and refueling freighters.
>Engineers believe the leaks are caused by microscopic cracks in the module’s structure. Russian cosmonauts have repeatedly inspected and attempted to seal the cracks, but a permanent fix has eluded them. After a few months of pressure stability inside the PrK earlier this year, Roscosmos confirmed in May that the air leaks had returned.
>“Following new leaks, Roscosmos has elected to proceed with a more extensive repair operation on Friday, June 5,” NASA spokesperson Bethany Stevens wrote on X. “Out of an abundance of caution, NASA has directed all four of the agency’s SpaceX Crew-12 members and NASA astronaut Chris Williams to assume an elevated safety posture in the Dragon spacecraft while the repair is underway.”
Send up a case of duct tape. You can fix almost anything with that stuff.
I was getting Interstellar Dr Mann depressurization vibes. I don’t think they can fix it. It’s in the adapter, and every time a Soyuz docks and undocks, it’s pressurized. You can’t fix the metal flexing. I’m doubting it will last past 2028, never mind 2030.
She is getting old boys and girls. As much as it pains me to say, its time to move on and spend the budget to go to mars.
The station was originally built using modules, is it completely infeasible to seal the bulkheads and then swap out the relatively small PrK section? Even if they had to move everyone out temporarily?
After all this time, and with all the tech available, it seems odd that we don’t have mini space drones, to buzz around outside spacecraft, identifying problems & (maybe) fixing them.
