Russian ISS module cracked in six places


For the first time, the public became aware of an air leak on the ISS in September 2019. Almost a year later, in August 2020, according to Roskosmos, the entire crew was isolated in the Russian Zvezda module while the pressure was checked in the American unit. Now from the conversations of the crew with the Earth, broadcast by NASA, it became known that the specified Russian module went cracks in six places.


We are talking about at least six cracks in the Zvezda module housing. The first should be finally eliminated (sealed) next week. She was found in October 2020, she is 4,5 cm long and is in an intermediate chamber. It is now temporarily sealed with rubber and aluminum foil.

On February 24, 2021, the area of ​​another likely crack was sealed with several layers of film (called a "dome") to determine if there is a real air leak or not.

From the Mission Control Center, the Russian cosmonaut Sergei Ryzhikov was told that on February 25, an examination of "crack No. 3, next to the butt joint" will take place. On February 26, it is planned to examine the “three cracks”, on which he had previously installed “domes”.

Note that according to statements from Roscosmos, the aforementioned air leaks are not dangerous for the crew. They are compensated by the reserves of air, nitrogen and oxygen, which are available on the ISS or are delivered from Earth by cargo spacecraft.

Currently, in addition to Ryzhikov, the ISS is home to the Russian cosmonaut Sergei Kud-Sverchkov, the American astronauts Kathleen Rubins, Michael Hopkins, Victor Glover and Shannon Walker, and the Japanese Soichi Noguchi.

    Fatigue of metal, violation of technology during assembly (welding), metal does not correspond to the declared one, poor quality assessment of the condition of the product - it can be anything. But one thing is for sure. It's a shame. Effective managers and the system of capital-state-business-deriban of the budget. The feeling that the station is "crumbling" ...
    It's time to change something!

      Why a shame? The station has been operating much longer than planned. The fact that these cracks have appeared only now is the opposite. an indicator of good quality of Russian modules.

            Different terms are laid on the technique. There is a warranty, there is a service life. Different units and elements also have different reliability. A body that provides structural rigidity and tightness must, by definition, have a huge margin of safety and, accordingly, in terms of time.

            The permissible maximum loads may have been exceeded.
            This is one of the extreme modules, to which cargo ships can be docked and for some time the cargo spacecraft within the ISS can be docked.

            There could be "hard" joints and, as a result, such a result that exists now as not single cracks due to metal fatigue.

      Interestingly, will the topic of the ISS flooding be raised?

      For the curious:
      (Nov 2020)
      “What will happen next after the International Space Station? It is planned to create additional posts outside the Earth. "
      https://www.space.com/international-space-station-future-off-earth-outposts
      (lane google)

      The ISS - the result of cooperation between the United States, Russia, Canada, Japan and the member states of the European Space Agency (ESA) - still has a significant resource: it is officially approved for operation until December 2024 and an extension until the end of 2028 seems likely. But the race to create stations has started.
      For example, Houston-based Axiom Space plans to use the ISS as a starting point for its own station in Low Earth Orbit (LEO).
      Axiom aims to start launching new commercial modules on the ISS in 2024 to provide astronauts with more living and research space on board the orbiting laboratory. And when the ISS is decommissioned, "the Axiom station will complete construction and will be disconnected from the ISS in order to operate in the future as a free-flying complex for life and work in space, which marks the next stage of human settlement in LEO," Axiom representatives wrote on the website companies.
      Axiom will also provide other services, including the purchase of tourist flights to the ISS aboard SpaceX's Crew Dragon capsules. Axiom has already signed a contract with SpaceX to that effect, and the first of these private missions is expected to launch in late 2021.
      California-based Orion Span has plans to build its own LEO station called Aurora, which the startup says could be launched in late 2021 and begin accepting customers next year. However, uncertainty about funding can complicate a company's goals. (Another company, Bigelow Aerospace, had long planned to establish private outposts in orbit and on the Moon. But Bigelow fired all of its staff in March this year.)
      There are also government space stations. China wants to build a low-Earth orbit outpost about the size of the Soviet-Russian Mir station, which was deliberately de-orbited in March 2001.) China wants to start assembling its station next year or so. The country has already made significant progress in this direction: since 2011, China has launched two prototype habitat modules into orbit and sent astronauts to both of them, as well as a robotic supply ship for the second.
      India also wants to have its own LEO outpost. The country is working to launch its first crewed mission into orbit in 2022, on the 75th anniversary of India's independence from the United Kingdom. This landmark launch will help pave the way for the space station to be launched by 2030 if all goes according to plan.

      So there are a lot of plans ....!

          Or maybe this is a reason for Russia to close the ISS

          Here is a list of ISS modules:
          The ISS consists of 16 sealed modules: four Russian modules (Pirs, Zvezda, Poisk and Dawn), nine American modules (Zarya, LUCH, Leonardo, Harmony, Quest, Calm, Unity, Dome and Destiny), two Japanese modules. (JEM-ELM-PS and JEM-PM) and one European module (Columbus).
          How these modules are functionally dependent / independent from each other - I do not know. I think that if they are independent, then a country whose module cannot be repaired can unfasten it and, somehow, sink it (with the help of a cargo ship). If they are functionally dependent, then options problems arise. It seems to me that after 2024 the countries' owners of the modules will not actively participate in supporting the station (waste of money) ...

            And if Russia leaves the program, the ISS will have to be drowned.

      It so happened that I knew some of the RKK leaders and their children. Before Rogozin. Well, in my opinion, it all started in the early 2000s. When not only there, but all over the country, "someone" was allowed to appoint (under the guise of corruption prevention), their beloved salaries (then still) that they want. No, of course we went, coordinated with Moscow. But everyone felt the difference. Including colleagues. Yes, and Rogozin came with criticism of the miserable existence of the lower classes.
      How it "worked" for the worse, you will not understand, but this is not required, but I know for certain ...
      PS Rogozin has changed little. RKK seems to be stuck in 2002-2003.

          True? And where is it written, in the article or in the comments, that the ship's skin has the same service life as the onboard electronics? And where is it written that it, the covering, was done under Rogozin?
          Or does the word "manager" itself automatically mean Rogozin?

              Loss of competencies, at the level of reproduction, not to mention development, is characteristic of many industries, not only in space. And Rogozin is criticized (deservedly) for a chronic inability to correct (already chronic) diseases. Well, a specialist for "uncle" with millions of monthly bonuses will not work normally if he brings home 25 rubles. A specialist and a non-specialist can protest against injustice only because he can protest ...!
