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.

Content: Soyuz manufacturing defect causes air leak at 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.

Content: Recently, during a spacewalk outside the International Space Station (ISS), an astronaut ’ s mask was hit by a contaminated rope, triggering an accident.
The spacewalk was broadcast live on NASA television, with the participation of two astronauts, Oleg Kononenko and Nikolai Chub.
While their mission includes a variety of targets, the focus of this mission is to investigate a radiator leak on the Nauka module that occurred earlier this month.
Checking for coolant leaks proved to be a challenge, as the astronauts initially found no signs of leaks on the takeover line.
However, upon closer inspection, they found traces near the radiator panel joints.
Further into the spacewalk, a large amount of cooling liquid was observed on a pipe at a radiator junction.
The astronauts tried to clean up the mess with towels, but apparently they didn ’ t have enough towels.
Unfortunately, one end of the tie is immersed in the coolant and touches the astronaut ’ s mask.
The incident prompted the two men to leave the area and continue on other missions, but the mission did not proceed as planned.
The deployment of the nanosatellite for the solar sail technology test failed and a synthetic radar communication system was installed, but one of the panels suffered a problem.
After the spacewalk, the astronauts checked the spacesuit for contamination and followed the usual decontamination procedures.
In order to ensure the safety of crew members, additional filtration systems will be used inside the ISS to eliminate traces of coolant left in the air.
The leak was initially detected by cameras aboard the International Space Station, and the crew confirmed this by visually inspecting the spare radiator on the Nauka module.
The radiator was delivered on the last Space Shuttle mission in 2010, but was only installed during the Russian spacewalk this year.
Next steps to fix leaks have not yet been determined by task managers.
Clearly, both Kononenko and Chub succeeded in identifying and isolating the leak, but the scope of further work required remains uncertain.
Fortunately, the main coolant loop was not affected, ensuring the safety of the crew in this accident.
Frequently Asked Questions:
Q: How did the event happen during the spacewalk?
A: The astronaut ’ s tether was immersed in cooling fluid and accidentally hit one of the astronauts ’ masks.
Q: What missions did the astronauts perform during the spacewalk?
A: The first task is to investigate and isolate the coolant leak on the Nauka module radiator.
They also attempted to deploy a nanosatellite to test the solar sail and install a synthetic radar communication system.
Q: Are the crew in danger?
A: The main coolant circuit is not affected, and the crew is not exposed to any direct danger.
Follow safety protocols to mitigate any potential risks associated with refrigerant leaks.

The air leak was eventually fixed, and the ISS continued to operate safely, with the crew taking necessary precautions to prevent similar incidents in the future.

The incident also highlights the importance of international cooperation in space exploration, as NASA and Roscosmos worked together to fix the leak.


The air leak at the International Space Station was first detected in 2019, with the leak rate increasing fivefold later.

The leak was located in the Zvezda module of the ISS, specifically in the intermediate chamber of the service module.

The exact cause of the leak was initially unknown, but it was later determined to be due to a crack in the Zvezda module.

The crack was found to be small, making it difficult to detect with detectors.

Russian cosmonauts, including Peter Dubrov and Anton Shkaplerov, played a key role in locating and attempting to fix the leak.

The leak was not found to pose a serious threat to the crew or the station, but it was still a concern that needed to be addressed.

The investigation into the cause of the leak was ongoing, and experts were working to determine the next steps to fix the leak.

The air leak was eventually sealed with a special sealant by cosmonauts in March 2021, which reduced the air leakage from 1.14 kg to 0.47 kg per day.

The repair work was led by the Main Operational Group of the ISS Russian Segment, and it was carried out by the ISS crew.

The incident highlighted the importance of international cooperation in space exploration, as NASA and Roscosmos worked together to address the issue.

The air leak incident also demonstrated the need for careful monitoring and maintenance of the ISS, as the station's aging infrastructure poses a risk to its safety and operation.

The experience gained from the air leak incident will be valuable for future space missions, including the importance of regular inspections and maintenance.

The incident also highlighted the importance of having backup systems and contingency plans in place for emergency situations.

The air leak incident on the ISS served as a reminder of the risks and challenges associated with space exploration and the importance of learning from experience to improve future missions.

ISS crew reports smoke and smell of burnt plastic
In the Russian module “Zvezda ” on the International space station (ISS) last night worked fire alarm, reports RIA“ Novosti ” with reference to the negotiations of the crew with the Earth, which broadcasts NASA.
Around five in the morning Moscow time, cosmonaut Oleg Novitsky told the Mission Control Center about the smoke and smell of burnt plastic.
After that, the devices showed the presence of harmful substances in the area of the medical cabinet in the Zvezda module.
French astronaut Tom Pesquet said that the smell of burnt plastic or electronics also penetrated the American segment of the ISS due to the working ventilation.
The source of the smoke and smell has not yet been identified.
The ISS included a system for removing harmful impurities.
Later, Roscosmos said that the smoke sensor and alarm system worked on the ISS “during automatic recharging of batteries. ”
Currently, all systems of the station are working normally, the department notes.
The Russian service module Zvezda docked to the ISS in July 2000.
Its main frame was built in the 1980s as the core of the Mir-2 space station, which was to replace the Mir station, but then it was decided to use it in the ISS program.
Zvezda allows a crew of three cosmonauts to stay in space, and the module can also dock with the Progress cargo ship, which once every three months delivers the necessary supplies to the station and adjusts its orbit.
In the fall of 2019, an air leak was recorded on the ISS.
A year later, the leakage rate increased fivefold.
Sequential sealing of the station compartments allowed us to establish that the cause of the leak was a crack in the Russian segment of the ISS - Zvezda.
The astronauts sealed it with a sealant, but the air leak continued.
Recently, during the survey of the International Space Station, cosmonauts found non-through cracks on the oldest module - "Dawn".
At the end of July, a meeting of the Presidium of the Scientific and Technical Council of Roscosmos took place, where it was noted that the station is breathing on incense.
The International Space Station will expire in 2024.
Earlier, Vladimir Solovyov, General Designer of the Energia Rocket and Space Corporation, predicted an avalanche of failure of numerous elements at the station after 2025.
This mainly concerns the tightness of the housing and complex computing facilities that have developed their resource, Solovyov noted.

Russia and the United States will determine the causes of cracks that are looking for on the ISS from 2020
Russian and American experts during the meeting determine the reasons that led to the formation of cracks in the transition chamber (PrK) of the service module "Star" of the Russian segment of the ISS.
This was announced on Wednesday by the chief specialist (RSC) "Energy" (included in).

“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 repair work was led by the Main Operational Group of the ISS Russian Segment, and it was carried out by the ISS crew.

"This Is Bad" - Russian Cosmonauts Discovery Tiny Cracks In Space Station

by Tyler Durden
Saturday, Sep 04, 2021 - 09:55 AM

Russian cosmonauts have discovered small cracks on the International Space Station (ISS), and it's unclear whether the cracks are causing air leaks in the orbiting space lab, according to Reuters

Vladimir Solovyov, the chief engineer of Moscow-based company Energia, the top contractor for Russia's spaceflight program, told Russia's state-owned RIA news agency that "superficial fissures have been found in some places on the Zarya module."

Solovyov warned: "This is bad and suggests that the fissures will begin to spread over time."

He didn't mention if the cracks were the source of air leaks which Russian cosmonauts discovered.

The 23-year old space station has been fraught with problems. NASA and the Russian Space Agency Roscosmos searched for a small air leak last year when air pressure dropped in the space station.

Readers may recall, in 2018, the station experienced an air leak that was initially thought to be the result of a micrometeorite - but turned out to be a "deliberate sabotage."

Several other recent incidents have been reported on the space station, such as a software glitch that ignited thrusters on the Russian research module Nauka and sent the ISS out of normal pitch. There was also a piece of space junk that sliced through a robotic arm

Meanwhile, Moscow has given their farewell warning that it will depart from the ISS in 2025. Russian officials have said the aging ISS is too dangerous for their cosmonauts:

"We can't risk the lives [of our cosmonauts]. The situation that today is connected to the structure and the metal getting old, it can lead to irreversible consequences - to catastrophe," Deputy Prime Minister Yuri Borisov recently said.

At the same time, China has launched a new space station that is expected to outlast the ISS.

The experience gained from the air leak incident will be valuable for future space missions, including the importance of regular inspections and maintenance.

The incident also highlighted the importance of having backup systems and contingency plans in place for emergency situations.

Content: Russian space corporation reports leak in its module of International Space Station

MOSCOW (AA): The Russian Space Corporation (Roscosmos) has reported a leak in its module of the International Space Station (ISS).

There was a leak of coolant from the backup radiator circuit of the multipurpose laboratory module “Science,” it said in a statement.

The main thermal control circuit of the module operates normally, providing comfortable conditions in the residential area and there is no danger to the crew and the station, it said.

The air leak incident on the ISS served as a reminder of the risks and challenges associated with space exploration and the importance of learning from experience to improve future missions.
