Russian astronauts locate another leak on Zvezda
According to Russia’s state-run TASS press, Russian astronauts have located what it calls “the last air leak” on the Zvezda module of ISS.
Russian cosmonauts Anton Shkaplerov and Pyotr Dubrov discovered the last air leak location in the International Space Station’s Zvezda module, Roscosmos spokesman Dmitry Strugovets said Tuesday, adding that the leak will be eliminated after special equipment is delivered to the station.
Like most of the other leaks previously found, this one was located in the aft transition chamber where the Zvezda docking port is located, once again suggesting that these leaks are the result of stress fractures caused by age and the more than a hundred dockings that have occurred there since Zvezda was launched more than twenty years ago.
The Russians’ belief that no more leaks will be found is probably based on their decision to reduce, even cease the use of this port. The new Prichal docking hub, which two Russians today are doing a spacewalk to finalize its integration with the station, makes the shuttering of Zvezda’s port possible.
At the same time, the existence of numerous stress fractures in an ISS module is not something to be dismissed lightly, as the TASS article attempts to do. It is akin to cracks in the hull of a submarine, and I don’t know anyone who would be willing to send such a vessel deep underwater.

astronauts locate another leak?
Willi: Thank you. Fixed.
Mr. Z:
Russian “astronauts”? Are there also American cosmonauts? :-)
Is Zvezda Russian for sieve?
Questioner,
Yes, Nancy Pelosi is an American Cosmonaut.
