The air leak at the International Space Station was first detected in September 2019.

The leak was found in the Russian segment of the ISS, specifically in the Zvezda module.

The air leak rate was approximately 325 grams per day, and it was later reduced to 0.47 kg per day after some repairs.

The leak was discovered by Russian cosmonauts, including Peter Dubrov and Anton Shkaplerov, who found the leak source in the intermediate chamber of the service module.

Initially, the cause of the leak was unknown, but it was later determined that cracks in the Zvezda module's housing were the likely cause.

The cracks were found in March 2021, and repair work was done under the Russian Segment leadership.

The air leakage decreased three times after sealing the cracks, but the exact cause of the cracks was still unknown.

It was speculated that the age of the station and technological solutions might have contributed to the cracks and subsequent air leak.

The ISS crew and station were not threatened by the leak, and experts regularly fixed air leakage on board the ISS.

A special committee was formed to investigate the accident cause, and the person responsible for the fault was identified, although the details were not publicly disclosed.

The leak was temporarily sealed with glue, but it later dried out, requiring further repairs.

The Russian space agency, Roscosmos, developed a plan to repair the leak and sent equipment via the Progress cargo ship.

The ISS operation was not significantly affected by the air leak, and the station is expected to continue operating until at least 2028 or 2030.

The air leak detection and repair efforts were a collaborative effort between NASA and Roscosmos, with the two agencies working together to eliminate the air leakage.

The experience with the air leak highlighted the importance of regular maintenance and inspection of the ISS, as well as the need for effective collaboration between international space agencies.

The air leak at the International Space Station was first detected in September 2019.

Vladimir Solovyov, chief designer at Energia, announced that astronauts have discovered new blind cracks in the Zaria module, the first and oldest module of the International Space Station.
Solovyov, in an interview with the Russian news agency Novosti, pointed out that the astronauts, during their examination of the units of the Russian sector on the International Space Station, discovered the presence of blind cracks in the old unit "Zaria".
According to him, this does not appeal to him, because the discovery of holes in the former Zvezda unit, indicates that the cracks discovered in the Zaria unit over time will inevitably expand.
In September 2019, astronauts detected a slight air leak from the International Space Station, in October 2020 they discovered cracks in the middle chamber of the Russian Zvezda unit, and in March 2021 they were able to repair them.
In January 2021, Solovyov announced that due to air leakage, the pressure inside the ISS drops by 0.4 mm Hg, which is compensated by pumping oxygen and nitrogen as well as transporting them from Earth.

Russia comments on space station leak

A NASA official had previously reported that air loss from the Zvezda module had doubled

Air leaking from a segment of the International Space Station (ISS) poses no risk to its crew or the orbital outpost, the Russian space agency Roscosmos has said.

A NASA official had previously reported that the rate at which air was escaping from the satellite's Russian Zvezda module under certain circumstances had doubled. The situation is under control and being constantly monitored, the Roscosmos told Interfax on Wednesday, when asked about remarks by NASA’s ISS program manager, Joel Montalbano,.

”The aging of the station’s structure and the growing need for repair and maintenance work on board require a significant portion of the crew’s time,” Roscosmos said.

Montalbano mentioned the issue during this week’s briefing on the upcoming SpaceX Crew-8 mission, which is scheduled for launch on Friday.

”There is an area in the aft end of the International Space Station. [There is] a small leak. We’ve seen this leak increase about a week before the recent Progress launch and docking,” he said, referring to a Russian automatic supply freighter.

The volume of lost air has increased to about two pounds a day, compared to a pound a day previously, Montalbano said.

”The hatch is closed in that area. It’s not an impact on Crew-8, but I didn’t want anyone to be surprised, if they hear about that later,” he explained.

The use of the module for retrieving the Progress shipment didn’t pose any issues in terms of the leak, he said. The next opening of the hatch is expected in April. While it’s closed, the rest of the station is “solid.”

Technical issues at the ISS are being reported on a regular basis. Roscosmos has said the age of the station is a key reason why it is developing plans for a new purely Russian-manned orbital structure as an alternative to participating in the international project.

“Now there is a meeting with American partners, why they [cracks] formed.
The first factor is age, <... > the second is technological solutions that eventually led to cracks, "Spirin said at the XLVII Academic Readings on Cosmonautics in memory of S. P. Korolev.
Video of the day
According to him, the leakage rate for the station is 325 grams per day.
“We stayed until 2019.
When the PrK was closed, we entered this norm, "the expert explained, stressing that if the camera is isolated and opened extremely rarely, then you can continue to fly to the ISS.
According to the presentation presented by Spirin, since the start of work on the search for the leak in September 2020, the damage to the shell has been localized and eliminated in three places.
"As a result of the work, the rate of air leakage from PrK was consistently reduced from 1.14 kg per day to 0.47 kg per day on a permanent basis and to 0.3 kg per day - on a temporary basis," the presentation emphasizes.
In March 2021, cosmonauts Roscosmos and Sergey Kud-Sverchkov carried out repair and restoration work on the housing of the Zvezda module, where they found a crack and a number of possible leaks.
All actions were carried out under the leadership of the Main Operational Group of the ISS Russian Segment and RSC Energia engineers and coordinated with specialists.
In mid-April 2022, a Roscosmos cosmonaut told reporters that air leakage had decreased three times after sealing the cracks.
XLVII Academic Readings on Cosmonautics in memory of S. P. Korolev (Royal Readings) are held at the Bauman Moscow State Technical University from January 24 to 27.

The leak was discovered by Russian cosmonauts, including Peter Dubrov and Anton Shkaplerov, who found the leak source in the intermediate chamber of the service module.

Air leakage occurred on the Russian segment of the ISS, the crew and the station itself is not threatened.
This writes TASS with reference to the press service of Roscosmos.
“Indeed, experts fix the leakage of air on board the ISS.
The crew regularly carries out work to find and eliminate possible leakage sites, and the data coming from the station are transmitted for analysis to specialists in the normal mode, ” the state corporation said.
According to "Interfax" with reference to the head of the NASA program on the ISS Joel Montalbano, the leak is observed in the tail part of the ISS.
“We saw that the leak increased about a week before the last launch of Progress and its docking with the station, ” he said.
The head of the NASA program on the ISS said that the air in the transition chamber of the Zvezda module began to leave twice as fast.
According to Montalbano, experts are in contact with Russian colleagues on the next steps.
However, this situation does not affect the safety of the crew, he said.
Last year, Russian cosmonauts Oleg Kononenko and Nikolai Chub in outer space disconnected the faulty circuit of the additional radiator on the module "Science" from the main circuit of the module.
Before that, they went into outer space, opening the exit hatch of the module "Search" of the International Space Station.

Kazakhstan News Agency / Astana / September 3 - According to the Russian satellite network reported on the 3rd, Russian rocket space sources said that the manufacturing defect is the cause of the "Soyuz MS-09" spacecraft leak.
There was an air leak on the International Space Station on August 30.
The astronauts examined all the compartments and found tiny cracks in the Soyuz MS-09 spacecraft.
It is located in the living module, not in the return module, so it will not affect the return of the spacecraft to Earth.
It was previously thought that the fissure was the result of a miniature meteorite hitting the spacecraft.
The next night, Russian cosmonauts used special sealant to fill the hole.
The source said: "The cause of the crack in the inner shell of the living module has been identified and it has appeared on Earth.
The person responsible for the fault was identified. "
According to another source, the crew likely sealed the leak with special glue after realizing the mistake, so it was not detected during the pre-launch check and the spacecraft ’ s first two months of orbital flight.
"However, the glue later dried out and was squeezed out, revealing cracks," he said.
The Russian space agency said a special committee would investigate and determine the cause of the accident.

The Russian Zvezda module, which is one of the modules of the Russian segment of the International Space Station, could be permanently isolated due to air leakage.
This was reported by NASA Director for the ISS Robin Gatens, reports “Interfax ”.
She said that the situation with the module does not yet pose a serious threat to the ISS, but in the worst case, is considering the option of complete isolation of the “Star ”.
According to Gatens, NASA and Roscosmos are working together to eliminate air leakage in the module, but due to the small size of the crack, it is difficult to detect detectors and ultrasonic diagnostic tools.
In turn, Roscosmos said that the concern of their colleagues on the ISS “is not justified and is surprising. ”
According to the Russian Ministry, the cosmonauts found the site of the leak at the end of last month.
They promise to fix the problem when the Progress cargo ship delivers materials to the ISS.
Note that in the Russian segment of the space station repeatedly there were problems and other problems.
For the first time, an air leak in one of the modules was detected in September 2019, in October 2020, a crack was detected in the camera of the Zvezda module.
Recall that earlier it was reported that at the end of July 2021, after docking the Russian module “Science ” to the International space station, it turned on the engines, because of which the station began to move chaotically and for a time lost control over the orientation of the ISS.

The air leak at the International Space Station was first detected in 2019, and it was found to be located in the Zvezda module.

The leak was caused by cracks in the hull of the Zvezda module, which were likely due to the age and technological solutions used in the module.

The air leak rate was initially 1.14 kg per day, but it was reduced to 0.47 kg per day after repair work was done in September 2020.

The repair work involved sealing the cracks in the Zvezda module, which decreased the air leakage by three times.

The cracks in the Zvezda module were sealed by Russian cosmonauts in March 2021, which further reduced the air leakage.

The air leak did not pose a serious threat to the ISS crew, but it did require ongoing monitoring and repair work.

The ISS Russian Segment experts led the repair work, and the leak detection and repair efforts have been ongoing since 2020.

The air leak was also detected in the Zaria module of the ISS, where non-through cracks were found.

The cracks in the Zaria module are expected to expand over time, but the ISS can still operate for 20 years with non-through cracks.

The repair equipment to fix the leak was sent via the Progress cargo vehicle, and the cosmonauts worked to restore the tightness of the Zvezda module.

The leak location was discovered by Russian cosmonauts, including Peter Dubrov and Anton Shkaplerov, who found the leak in the middle chamber of the Zvezda unit.

“In the worst case scenario, we can permanently isolate this module, ” she said at a meeting of the committee on space exploration and manned flights of the Advisory Board of NASA.
At the same time, Gatens stressed that the situation with the Zvezda module does not pose a serious threat, there is a sufficient supply of air at the station.
The head of the press service of Roscosmos Dmitry Strugovets recalled that Russian cosmonauts Peter Dubrov and Anton Shkaplerov in late December found a possible last place of air leakage in the intermediate chamber of the service module “Star ”.
Necessary to eliminate leakage means are planned to be delivered on the nearest cargo ship "Progress".
“The concern of our partners is unreasonable and surprising, ” he said (quoted by TASS).
The first crack in the intermediate chamber of the “Star ” cosmonauts discovered in October 2020.
It was sealed in March of this year, but the leakage of oxygen did not stop, although it decreased.
In total, three locations were found, including in the Zvezda intermediate chamber, where cracks could potentially form.
On February 24, 2021, the crew made a temporary isolation of all potential cracks to find out exactly whether there was a leak in these places.
At the end of April, the search was temporarily stopped, and the hatch in the compartment was closed.
In July, the ISS crew resumed the search for the site of air leakage in the Zvezda module.
