Due to cracks, Russia will no longer use Zvezda’s docking port
Russian officials today revealed that they will no longer use the docking port on its Zvezda module on ISS because of the stress fracture cracks they have found in the section where that port is located.
Russia is unable to use one of the docking ports of the ISS to its full extent due to cracks in the transitional chamber of the Zvezda module, the general designer of Russia’s Energia corporation, associate member of the Russian Academy of Sciences Vladimir Solovyov said on Monday. “The transitional chamber’s loss of airtightness is often mentioned these days. We are very fortunate the cracks are at the end. We shut down that compartment, thus losing one docking port, which narrows our opportunities somewhat. The crack is very insignificant, though,”
In other words, they have sealed the aft section of Zvezda to reduce further air leaks, thus also closing off access to the port.
The Russian portion of ISS presently has two docking ports on two different modules. When Roscosmos launches its Prichal docking hub in November, to be attached to Nauka’s port, they will then add four more ports.
This decision underlines the impending end to ISS’s life span. Zvezda is not the only old Russian module on ISS where stress fractures have been found. “In August they found cracks in the module Zarya, the oldest module on ISS.
Though the U.S. part of ISS shows no such problem, it is designed to rely on the Russian half for its operations. If Russia must shut down its modules then the station will not be able to function for much longer.
The U.S. will likely overcome some of these issues with the planned launch in ’24 of Axiom’s private commercial module to ISS, which will eventually evolve into an complete space station separate from ISS. For the Russians the pressure to design and launch their own new station has become more critical. Whether they can do it however is unknown. Russia has not built a new space station module in decades. Their new ISS module, Nauka, was built in the 1990s.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

So far I think there has been 100 dockings to the aft port of the Zvezda module, not counting any re-dockings. I was going to make a joke parodying “100 bottles of beer on the wall”, but the serious question I had is how will they boost the station’s orbit with the Progress spacecraft if they can’t park it there? I did some reading and Nauka has a fuel line connection to Zvezda. Progress feeds Nauka, Nauka feeds Zvezda, and Zvezda uses its engines to boost the orbit.
When the time comes to retire the ISS, don’t let it burn up in Earth’s atmosphere. Send it to the Earth-Moon L1 liberation point. Then put a large cage around it. Later on, there would be a pressurized tube around it. From inside the tube, tourist could see the ISS, old spacecraft, and old satellites. All of that would be in the metal cage.
With Spacex Starship, it will cost about $20,000.00 to go to the Moon, and back. The spacecraft could make a stop at L1, and the passengers could then see the ISS.
I agree-no point Nemo!
