The International Space Station experienced an air leak, detected in August 2019, at a rate of about 1 kilogram per day.

The leak in the ISS's Russian Zvezda module posed no risk to the crew or station.

A suspected crack or seal failure caused a leak, which was located in the Zvezda module using a tea bag.

The ISS loses 250 grams of oxygen daily, which is replenished through electrolysis.

A crack in the Zvezda module was found to be the cause of an air leak detected in 2019, with a fivefold increase in leak rate by 2020.

Russian cosmonauts found small cracks and air leaks on the ISS's Zarya module in 2020.

The cracks were suspected to have been caused by the ISS's age and technology, and three leak locations were found and fixed.

The air leakage was reduced from 1.14 kg to 0.47 kg per day, and further to 0.3 kg per day after repairs.

The Zvezda module's cracks were sealed in April 2022, reducing air leakage three times.

NASA and Roscosmos collaborated to stop the leak, which was isolated to the Zvezda module.

The small crack was difficult to detect, but cosmonauts found the leak and reported it to Flight Control.

Cosmonauts temporarily repaired the crack the previous October, and a Progress cargo ship was to deliver permanent fix materials.

The leak was eventually solved with repair equipment sent on a Progress cargo vehicle.

The leak was temporarily repaired and module tightness was restored with the help of delivered equipment.

A few years ago, a torn bag helped save the ISS
The International Space Station was built in 1998 for $150 billion.
Every year, another 3-4 billion dollars are spent to maintain its operability, but the design is already very old and needs repair more and more often.
For example, in August 2020, a pressure drop was recorded aboard the space station, which is a sign of an air leak.
All astronauts and cosmonauts on board were isolated in the Russian Zvezda module.
After some time, it was found out that the air-permeable crack was in the module in which the entire crew temporarily settled.
One of the Russian cosmonauts was able to quickly find the place of leakage with the help of a usual tea bag.
Oxygen on the ISS
According to the India Times, the space station loses about 250 grams of oxygen every day and this is normal - it is difficult to achieve complete tightness.
In the event of an acute shortage of oxygen, it is delivered by cargo ships, but is most often produced directly at the station.
In the second case, members of the ISS use electrolysis - an electric current is passed through the water, as a result of which oxygen appears.
To do this, on board there is a life support system ECLSS, which not only monitors the operation of the station, but also provides people with access to water, protects against fires and so on.
ECLSS technical director Robyn Carrasquillo once praised Russia for using a way to extract moisture from the air, even in the old Salyut and Mir spacecraft.

Oxygen leakage to the ISS
In August 2020, the space station began to lose about a kilogram of air per day.
The situation was serious, but the lives of the ISS crew were not threatened.
Astronauts from different countries temporarily began to live in the Russian module “Zvezda ” and for four days searched for a leak in other parts of the station.
The search did not give any results, so it became clear that the gap is in the Zvezda module launched more than 20 years ago.
The leak could have occurred for various reasons, for example, due to the collision of the ISS with space debris, which is a lot in near-Earth space.
Also, it was not excluded that seals simply peeled off from the walls of the station, which just do not allow oxygen to leak.

Search for the place of oxygen leakage
An unusual way to find the leak was found by cosmonaut Anatoly Ivanishin.
He installed several cameras in the module and opened the tea bag.
After some time, the ISS members noticed that the tea leaves began to move slowly towards one of the metal walls of the module.
After studying the trajectory of the leaves, the space crew quickly found the crack formed on the ISS.
First, they taped this place with tape, and then got permission to use a drill and sealant.
It is known that thanks to the trick with a package of tea, the astronauts managed to save about 150 billion dollars.

The International Space Station is aging and will one day become completely unusable – that ’ s a fact.
New cracks were discovered even in 2021.
Especially there are many of them in the Russian module “Zarya ”, which was launched into space in 1998 and today is the oldest part of the station.
More recently, Vladimir Solovyov, General Designer of the Energia Rocket and Space Corporation, announced his concerns about the safety of the station.
It is especially frightening that the station is planned to be used even after 2025.
In theory, the use of the old station could cause a terrible disaster.

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.

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.

"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 cracks were suspected to have been caused by the ISS's age and technology, and three leak locations were found and fixed.

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 air leakage was reduced from 1.14 kg to 0.47 kg per day, and further to 0.3 kg per day after repairs.

The Zvezda module's cracks were sealed in April 2022, reducing air leakage three times.

NASA and Roscosmos collaborated to stop the leak, which was isolated to the Zvezda module.

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 August 2020, although initial signs of the leak were observed in September 2019.

The leak was found to be located in the Russian Zvezda module of the ISS.

A crack in the Zvezda module's transition chamber was identified as the cause of the air leak.

The air leak rate was measured at 325 grams per day.

The age and technological solutions used in the ISS were identified as possible causes of the cracks that led to the air leak.

The ISS crew reported that the leak posed no risk to the crew or the station.

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

The leak was initially detected in September 2019, but the location was only found later, in December, by Russian cosmonauts.

A temporary repair was made to the crack in October 2020, but a more permanent fix was needed.

The ISS operated with non-through cracks for some time, which did not immediately affect its operation, but still required attention.

The Russian space agency, Roscosmos, sent a Progress cargo ship with equipment to fix the leak.

The cosmonauts used the delivered equipment to begin the final leak elimination process.

The air leak was eventually sealed, reducing the leakage rate three times, from 1.14 kg to 0.47 kg per day, and then to a temporary rate of 0.3 kg per day.

The leak was fixed using special sealants, and the ISS crew worked to find and eliminate other potential leakage sites.

The incident highlighted the need for regular maintenance and repair of the ISS, which is a joint international project that has been in operation since 1998.

The air leak at the International Space Station was first detected in August 2020, although initial signs of the leak were observed in September 2019.

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.

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 air leak rate was measured at 325 grams per day.

The age and technological solutions used in the ISS were identified as possible causes of the cracks that led to the air leak.

The ISS crew reported that the leak posed no risk to the crew or the station.

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.

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

On the International Space Station, a place of possible air leakage in the Zvezda module was discovered.
The discovery of a "suspicious" place in the module compartment was reported by cosmonaut Pyotr Dubrov during negotiations with the Flight Control Center.
“There was a suspicious place.
I was engaged in photographing it under a microscope with magnifying glasses, ” the cosmonaut quoted Interfax as saying.
Recall that in August 2020, air leakage to the ISS was detected in the transition chamber of the Zvezda module.
In October last year, cosmonauts managed to find the crack and repair it with temporary means.
In August 2021, the media reported the detection of non-through cracks in the Russian module of the ISS "Zarya".
Executive Director of Roscosmos for manned programs Sergei Krikalev said then that he had no information about new cracks at the station.
At the same time, the representative of the state corporation noted that even in the presence of non-through cracks, the ISS can be operated for another 20 years.

The media office of the Roscosmos Foundation announced that the Russian cosmonauts discovered in the unit "Zvezda", the possible place of air leakage from the International Space Station.
According to the information office, the materials and equipment needed to repair this place will be sent aboard the Progress cargo vehicle.
"The equipment and materials necessary to stop air leakage will be sent with the first Progress cargo vehicle launched to the International Space Station, to solve this problem once and for all," the statement said.
Astronauts Peter Dobrov and Anton Shkaplerov discovered the possible location of the air leak in December in the middle chamber of the Zvezda unit.
NASA has said it is considering isolating the Zvezda module completely if necessary.
The Roscosmos media office commented: “The concerns of our partners are unfounded and surprising. ”

A temporary repair was made to the crack in October 2020, but a more permanent fix was needed.

The ISS operated with non-through cracks for some time, which did not immediately affect its operation, but still required attention.

The Russian space agency, Roscosmos, sent a Progress cargo ship with equipment to fix the leak.

Moscow, January 18.
Astronauts of the Russian segment of the International Space Station have discovered a possible place of air leakage in the chamber of the Zvezda module.
The relevant data follows from the material published by the press service of Roscosmos.
It is known that soon the nearest cargo ship "Progress" will be delivered to the ISS means of eliminating leakage.
After that, the Russian cosmonauts will immediately begin the final elimination of the cause of the leak.
"The means of eliminating non-hermeticity are planned to be delivered on the nearest Progress cargo ship, after which the cosmonauts will begin the final elimination of the leak," Roscosmos said.
Earlier, Russian cosmonauts Peter Dubrov and Anton Shkaplerov discovered a potential last place of air leakage in the Zvezda module.
Specialists will be able to restore its tightness as soon as Progress delivers the necessary equipment to the station.

The cosmonauts used the delivered equipment to begin the final leak elimination process.

The air leak was eventually sealed, reducing the leakage rate three times, from 1.14 kg to 0.47 kg per day, and then to a temporary rate of 0.3 kg per day.

The leak was fixed using special sealants, and the ISS crew worked to find and eliminate other potential leakage sites.

Roscosmos said that the causes of microcracks on the ISS are not yet known

The question of the causes of microcracks on the International Space Station (ISS) is still open.
This was announced by the executive director of Roscosmos for manned space programs Sergey Krikalev in an interview with Gazeta.ru.
Krikalev noted that the pressure inside the station varies depending on temperature, humidity, oxygen consumption and carbon dioxide emissions.
And it changes in "a much wider range than from these leaks."
“To see a very small slope of the overall trajectory, it takes time.
You will not see these changes on daily schedules.
Since these are microcracks, no leak detectors detect them.
Nevertheless, we were able to determine the compartment, some of the microcracks are localized, repair work is being carried out, ” Krikalev explained.
According to him, the effect of metal fatigue has nothing to do with it - cracks were not found in loaded places.
Also, according to Krikalev, a number of solutions have been developed to eliminate leaks, but it has not yet been possible to do this until the end.
“We tried to cover these places with a special sticky tape, then we used special sealants.
On Earth, a special technological operation has been developed how to do it.
Leaks decreased, but did not disappear until the end, ” the expert said.
Earlier it became known that the ISS evaded space debris with the help of engines of the Russian module “Star ”.
The engines of the module were turned on at 18: 00 Moscow time.
They worked 21.5 seconds and gave a pulse of 0.3 meters per second.
Currently, the crew of the 69th long-term expedition is working on the ISS, consisting of cosmonauts of the state corporation Sergei Prokopyev, Dmitry Petelin and Andrei Fedyaev, as well as NASA astronauts Francisco Rubio, Stephen Bowen and Woody Hoburg and astronaut of the United Arab Emirates Sultan al-Neyadi.

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.
