The International Space Station experienced an air leak first detected in September 2019, with the leak rate increasing fivefold by 2020.

A crack in the Russian Zvezda module's transition chamber, discovered in October 2020, caused the leak.

The crack was likely caused by the age and construction technology of the Zvezda module.

Cosmonauts detected the air leak, located it using a tea bag, and initially sealed it with tape.

A drill was used to apply a sealant, including a self-tapping screw, superglue, and cold welding, to the leak.

The leak was not detected until after the spacecraft was launched.

A special committee found that dried-out glue caused a crack in the living module's inner shell.

The committee's findings identified the person at fault and led to recommendations for improving ISS safety and reliability.

In March 2021, sealing two cracks on the Zvezda module reduced air leakage from 1.14 kg to 0.47 kg per day.

In April 2022, repair work sealed cracks, reducing air leakage three-fold.

The leakage rate was temporarily reduced to 0.3 kg per day after April 2022 repairs.

Materials for the April 2022 repair work were delivered by a Progress cargo ship.

Roscosmos and NASA's collaboration has improved ISS safety and reliability, particularly after the air leak incident.

The two agencies are working together to investigate the leak, rescue stranded astronauts, and prevent similar incidents.

The ISS has spare equipment and receives necessary supplies from Roscosmos to ensure safety and reliability.

The air leak incident highlighted the importance of international cooperation and rigorous safety protocols in space exploration.

The International Space Station experienced an air leak first detected in September 2019, with the leak rate increasing fivefold by 2020.

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 crack was likely caused by the age and construction technology of the Zvezda module.

Cosmonauts detected the air leak, located it using a tea bag, and initially sealed it with tape.

How did a bag of tea help astronauts save $150 billion?
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.
ECLSS system
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.

Finally, I note that to replace the old module "Dawn" it was planned to send the module "Science".
But it became an independent module and docked to the ISS in July 2021.
The docking was far from perfect - the module deployed the station at 45 degrees.

Content: A gas tank leak, whether it is damage or through corrosion, always comes suddenly.
A puddle of fuel under the car is not only a fire hazard situation, but also a high probability of simply not getting to the maintenance station.
What to do in this case, says the portal “AvtoVzglyad ”.
So, there's a drop.
It's a puddle.
It is always found in the same way – the nose.
If one of the elements of the fuel system flows in the car, then the aromas around will be stunning.
In the literal and figurative sense of the word.
By the way, this usually happens at a gas station: refueling “to full ” can become fatal, giving an excessive load on the tank.
Having determined that the cause of the "gasoline flow" was the tank, you need to immediately take measures - any spark will turn the car into a torch.
It is clear that the best option is a tow truck to the service.
Where to get it and how to pay it?
In modern Russian realities, delivery to a familiar master can overlap the price of the car.
Our country is big but not rich.
In short, it is necessary to patch on the spot and slowly go, regularly looking at the fuel arrow.
Repair should begin with the jack and localization of leakage.
It is not difficult: there will be a wet spot around it.
As soon as the gap is revealed, a decision should be made: if the weld has burst, then it is half the trouble.
After all, the tank can be filled to half and go.
Much worse, when the hole was formed in the bottom - here you need to roll up the sleeves.
Having dropped the terminal from the battery - we do not need a spark at all - we disperse the onlookers and advisers, put the jack and climb under the car.
The Soviet method is a self-tapping screw with a rubber gasket.
From the mat, from the hose, from the sealant - from anything that comes by hand - we cut the washer and pull it to the place (look into the trunk, suddenly there was a sealant).
Self-tapping, by the way, can be unscrewed from the fender.
By the way, this option is equally good for both old, iron tanks and new plastic ones.
The second option is superglue.
He must be in the glove compartment or in the trunk.
Having cleaned the place around the gap from loose dirt - it will degrease itself - glue a rubber patch.
And glue the cross: first one strip, then, on top of it, the second.
The third option is cold welding.
Practice suggests that it can last for several weeks, but subject to a more thorough surface treatment.
In a word, breathe well.
The more diligent the repair, the greater the chance to safely get home.
In general, the leak suggests that the “tank ” is worn out and needs to be replaced, so tinning and other clever schemes are plugging holes in the literal and figurative sense.
So the appearance of a hole in the fuel tank says only one thing – it ’ s time to order a new part.
But first you just need to get to the house - this old tank with a homemade latka is just enough.

The leak was not detected until after the spacecraft was launched.

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.

International Space Station (ISS).
ISS) is a manned orbital station used as a multi-purpose space research complex; it is operated from the end of 1998 to the present (the countries agreed to operate through 2024 inclusive, the extension of the period of operation to 2028, 2030 is being considered).
The ISS is a joint international project involving 14 countries: Russia, the United States, Japan, Canada and members of the European Space Agency Belgium, Germany, Denmark, Spain, Italy, the Netherlands, Norway, France, Switzerland, Sweden (originally the participants were Brazil and the United Kingdom).
The ISS is controlled by the Russian segment from the Space Flight Control Center in Korolev, the American segment from the Lyndon Johnson Flight Control Center in Houston.
The European Columbus and Japanese Kibo modules are controlled by the European Space Agency (Oberpfaffenhofen, Germany) and the Japan Aerospace Exploration Agency (Tsukuba).
There is a constant exchange of information between the centers.

The Russian space agency is considering sending an airship to the ISS to return the crew to Earth.
Russian state media "RT" reported on the 23rd, the Russian Federal Space Agency (Roscosmos) said that a cooling agent leak on the Soyuz MS-22 (Soyuz MS-22) may lead to the early launch of another unmanned Soyuz spacecraft, in order to bring back the three astronauts stranded in the International Space Station (ISS) back to Earth.
Sergei Krikalev, head of the Roscosmos manned space flight program, said in a video conference on Tuesday that no final decision had been made on the matter.
NASA ISS program manager Joel Montalbano said that experts from the U.S. and Russia space agency are “working as usual ” to investigate the leak on the Soyuz last week.“ The team is coming back and forth, and we ’ re constantly exchanging data. ”
Russian cosmonauts Dmitry Petelin and Sergey Prokopyev, along with American astronaut Frank Rubio, have reportedly been on the ISS station since September, and the trio plan to return to Earth using the Soyuz MS-22, but according to Roscosmos and NASA, the hole, a few millimetres wide, has affected a piece of coolant in the spacecraft. The liquid released by the leak does not contaminate the outer surface of the ISS, such as solar panels or windows.
Krikalev said a thermal analysis is underway to determine whether Soyuz MS-22 is suitable for taking astronauts home, or “whether we need to send a rescue vehicle to the space station in the future. ”
In the latter case, the Soyuz MS-23 would have to fly to the ISS to meet Petelin, Prokopyev and Lubio, while the Soyuz MS-22 returned to Earth empty-handed.
Krikalev pointed out that although the Soyuz MS-23 is scheduled to launch in March 2023, it can be launched in February if the situation requires it.
If this happens, future rotations of crew going to the ISS will have to be “recalibrated. ”

Borisov: Roscosmos and NASA are constantly engaged in the safety of the ISS crew
As stated by the Director General of Roscosmos, the station is a lot of spare equipment for the rapid replacement of failed units
Moscow, October 27.
/ TASS /.
Roscosmos, together with the National Aeronautics and Space Administration (NASA), is constantly engaged in ensuring the safety of the crew of the International Space Station (ISS).
This was stated by the Director General of Roscosmos Yuri Borisov in an interview with the TV channel “Russia-24 ”.
"Indeed, we will celebrate 25 years of the International Space Station.
The first module was launched back in 1998.
Of course, nothing is eternal.
The station is getting old.
Nevertheless, the issue of crew safety is a paramount issue, and we are in close contact with our colleagues from NASA are constantly working, first of all, on crew safety and the continuation of the station ’ s work, ” Borisov said.
According to him, the ISS is a lot of spare equipment for the rapid replacement of failed units.
“We supply our trucks with all the necessary equipment, which is constantly changing, ” the head of Roscosmos added.

The air leak incident highlighted the importance of international cooperation and rigorous safety protocols in space exploration.


The air leak at the International Space Station was detected in August 2020, and it was initially suspected to be caused by a miniature meteorite hitting the spacecraft.

However, further investigation revealed that the leak was caused by a crack in the Zvezda module's transition chamber, which was found to be increasing the air loss rate.

The air leak rate was reported to be around 325 grams per day, with a total air loss of 1.14 kg per day, which was later reduced to 0.47 kg per day.

The leak was localized and temporarily sealed by Russian cosmonauts in 2021, using a special sealant, which reduced the air leakage by three times.

The cause of the crack was attributed to the age and technological solutions of the ISS, with similar cracks found in other modules, including the Zarya module.

The ISS crew was not in danger due to the air leaks, but the situation highlighted the need for continued monitoring and maintenance of the ISS.

The air leaks were investigated by NASA and Roscosmos, who worked together to eliminate the leaks and ensure the safety of the ISS crew.

The investigation into the causes of the air leaks involved analyzing data from various sources, including the ISS's life support system and the spacecraft's telemetry data.

The air leaks were eventually sealed, and the ISS continued to operate safely, with the crew conducting spacewalks and other activities as planned.

The experience highlighted the importance of regular maintenance and inspections to prevent similar incidents in the future.

The ISS has been in operation since 1998 and has been extended to operate until at least 2024, with ongoing maintenance and repairs necessary to ensure its continued safe operation.

The air leak incident demonstrated the effectiveness of international cooperation in space exploration, with NASA and Roscosmos working together to resolve the issue.

The incident also highlighted the importance of having a reliable and safe means of transporting crew and cargo to and from the space station.

The air leak was detected using a combination of methods, including the use of a tea bag to locate the leak, and was eventually sealed using a special sealant.

The ISS crew played a crucial role in detecting and sealing the air leak, and their actions helped to prevent any serious consequences.

The air leak incident was one of several challenges faced by the ISS, including ammonia leaks and other system failures, but the station has continued to operate safely and effectively.

The incident demonstrated the importance of continued investment in space research and development, with the ISS serving as a critical platform for scientific research and experimentation.

The air leak was eventually fixed with materials from a Progress cargo ship, and the station's life support system was restored to normal.

The ISS received oxygen and nitrogen from Earth to compensate for the leak, and the cracks in the Zaria module were expected to expand over time.

The Zaria module is the first and oldest module of the ISS, and astronauts examined the Russian sector units for damage regularly.

An air leak was detected in the Russian Zvezda module of the ISS, and the ISS can isolate the Zvezda module due to air leakage.

NASA and Roscosmos worked together to fix the leak, and the leak site was found by cosmonauts at the end of the previous month.

The Progress cargo ship was to deliver materials for the repair, and the first air leak was detected in September 2019.

A crack was detected in the Zvezda module camera in October 2020, and the ISS is a joint international project involving 14 countries.

The ISS has been operated from 1998 to the present, with a planned extension, and the Russian segment is controlled from the Space Flight Control Center.

The air leak at the International Space Station was detected in August 2020, and it was initially suspected to be caused by a miniature meteorite hitting the spacecraft.

Russia is developing its own space station.
What will it look like?
The International Space Station was launched into orbit around our planet in 1998.
Initially, it was planned that it will work for 20 years, but subsequently the period of its use was extended.
According to the opinion
On the ISS found a place of air leakage.
What's next?
Inside the International Space Station live astronauts from different countries and they all need oxygen.
The air necessary for the life of the crew is produced by special equipment, but
Space debris nearly damaged the ISS.
How did it all work out?
Humanity began to actively explore space with the help of complex technology around the middle of the 20th century.
First, hundreds were launched into Earth orbit every year, and then thousands began to be launched.

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.

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 leak was localized and temporarily sealed by Russian cosmonauts in 2021, using a special sealant, which reduced the air leakage by three times.

The cause of the crack was attributed to the age and technological solutions of the ISS, with similar cracks found in other modules, including the Zarya module.

The ISS crew was not in danger due to the air leaks, but the situation highlighted the need for continued monitoring and maintenance of the ISS.

Content: Russian spacecraft began an uncontrolled leak on Wednesday night
Russia ’ s spacewalk was canceled at the last minute on Wednesday night when a spacecraft attached to the International Space Station detected an unexpectedly large leak.
Cosmonauts Sergei Prokopyev and Dmitry Petlin were in spacesuits with a sealed airlock when air traffic controllers told them to prepare to investigate a leak in the Soyuz spacecraft.
The spacewalk was subsequently canceled shortly before 22: 00 ET (03: 00 UTC on Thursday).
The leak appears to have originated from an external cooling circuit located at the back of the Soyuz MS-22 spacecraft.
Public relations officer Rob Navias, commenting on the spacewalk for NASA television, described the spacecraft as "quite dramatic."
In the video of coolant leakage, you can see that particles are constantly pouring out of the Soyuz, which is a pretty cool spectacle.
None of the space station crew were in danger, including Prokopyev and Petlin, their fellow astronaut Anna Kikina; NASA astronauts Frank Rubio, Nicole Mann and Josh Cassada; and Japanese astronaut Koichi Wakata.
The leak occurred outside the station, not inside the orbiting lab.
However, the leak raises questions about the viability of the Soyuz spacecraft, the return flight to Earth by Prokopiev, Betlin and Frank Rubio from NASA.
They went to the space station again in September aboard the Soyuz spacecraft and are scheduled to return to Earth next spring.
Three hours later, Monday night, the leak was still going on and was not going to diminish.
Soyuz is a very tough spacecraft, so it is likely that this will not affect its ability to separate from the space station and return to Earth.
However, if Russian engineers — and engineers from NASA, given Rubio will be on board — determine that the problem exists, a new Soyuz will need to be delivered to the station.
Soyuz ships can be launched and docked independently.
However, this would mean that until the new spacecraft arrives, the three crew members will not have a rescue ship.
Golovin sowed chaos in the victory of Russia over Finland at the European Championships
The other four astronauts arrived aboard the station on the SpaceX Crew Dragon spacecraft in October.
This ship cannot accommodate seven people to return to Earth.
Given the duration of the spill, NASA likely also had concerns about the impact of all this ammonia on the surface of the space station and other docked vehicles.
Most of the ammonia is likely to evaporate from the surface of the device over time, but that will certainly complicate operations as the U.S. space agency works on its own spacewalk on Dec. 19 to install new solar panels.

The air leaks were investigated by NASA and Roscosmos, who worked together to eliminate the leaks and ensure the safety of the ISS crew.

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.

International Space Station (ISS).
ISS) is a manned orbital station used as a multi-purpose space research complex; it is operated from the end of 1998 to the present (the countries agreed to operate through 2024 inclusive, the extension of the period of operation to 2028, 2030 is being considered).
The ISS is a joint international project involving 14 countries: Russia, the United States, Japan, Canada and members of the European Space Agency Belgium, Germany, Denmark, Spain, Italy, the Netherlands, Norway, France, Switzerland, Sweden (originally the participants were Brazil and the United Kingdom).
The ISS is controlled by the Russian segment from the Space Flight Control Center in Korolev, the American segment from the Lyndon Johnson Flight Control Center in Houston.
The European Columbus and Japanese Kibo modules are controlled by the European Space Agency (Oberpfaffenhofen, Germany) and the Japan Aerospace Exploration Agency (Tsukuba).
There is a constant exchange of information between the centers.

Content: Due to a recent coolant leak on the Russian portion of the International Space Station (ISS), NASA officials decided to postpone a scheduled spacewalk.
The spacewalk, originally scheduled for Thursday, 19, 2023, will now take place later in the year as both NASA and the Russian Federal Space Agency (Roscosmos) continue to investigate the cause of the leak.
The coolant used on the International Space Station is ammonia, and additional purification procedures are required if astronauts wearing spacesuits are close.
The leak of the science module in Nauka, Russia, occurred on September 10, but stopped on the same day.
This is the third ammonia leak from Russian International Space Station equipment last year.
Roscosmos is scheduled to conduct its own spacewalk on May 13 to scrutinize a re-installed radiator on the Rassvet module that appears to be the source of the latest leak.
While the coolant is non-toxic or harmless to the crew, experts are working to prevent any trace substances from entering the internal system and causing equipment degradation over time.
NASA ’ s delayed spacewalks are designed to perform small maintenance missions.
NASA astronaut Lola O'Hara and European Space Agency astronaut Andreas Morganson will collect samples from the outside of the International Space Station to look for microbes and replace high-definition cameras for missions like these.
The exact date of this work will be determined at a later date.
Fortunately, NASA ’ s second spacewalk, the all-female spacewalk on March 30, is still on schedule.
O'Hara will work with NASA astronaut Jasmin Moghbeli to remove the faulty electronics box and replace the bearings needed for one of the station's solar arrays.
According to Russia, the first two ammonia leaks on the International Space Station were caused by micrometeoroid impacts.
In 2023, the first leak was so severe that the crew of the Soyuz spacecraft had to be reassigned to a replacement Soyuz spacecraft.
It took several spacecraft transports to resolve the problem, resulting in the astronauts staying on the ISS for a year instead of the original six months.
In October, the Russian Progress cargo ship also experienced an ammonia leak.

The air leaks were eventually sealed, and the ISS continued to operate safely, with the crew conducting spacewalks and other activities as planned.

Content: The pressure on the Russian International Space Station has dropped.
Font Size:
(Morning News) The head of the Russian space agency said on Saturday (31) that the pressure of the Russian "Star" service module on the International Space Station was once reduced due to air leakage.
Reuters reported that the Zvezda pressure drop occurred two weeks before the space station's position shift event.
After the Russian experimental module Nauka docked with the space station on Thursday, its thrusters suddenly started abnormally, causing the station to shift its position.
Dmitry Rogozin, head of the Russian space agency, said the two incidents were not related.
According to a statement from the Russian space agency, the pressure drop on the Starship was caused by a known minor air leak in a transit compartment, and that pressure will rise over the next 24 hours.
Russia said Friday that the emergency caused by the accidental reignition of the rocket ’ s thrusters on Thursday may have been caused by software glitches and human negligence.

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.

The ISS has been in operation since 1998 and has been extended to operate until at least 2024, with ongoing maintenance and repairs necessary to ensure its continued safe operation.

The air leak incident demonstrated the effectiveness of international cooperation in space exploration, with NASA and Roscosmos working together to resolve the issue.

The incident also highlighted the importance of having a reliable and safe means of transporting crew and cargo to and from the space station.

The air leak was detected using a combination of methods, including the use of a tea bag to locate the leak, and was eventually sealed using a special sealant.

The ISS crew played a crucial role in detecting and sealing the air leak, and their actions helped to prevent any serious consequences.

The air leak incident was one of several challenges faced by the ISS, including ammonia leaks and other system failures, but the station has continued to operate safely and effectively.

The incident demonstrated the importance of continued investment in space research and development, with the ISS serving as a critical platform for scientific research and experimentation.

The air leak was eventually fixed with materials from a Progress cargo ship, and the station's life support system was restored to normal.

The ISS received oxygen and nitrogen from Earth to compensate for the leak, and the cracks in the Zaria module were expected to expand over time.

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.

The Zaria module is the first and oldest module of the ISS, and astronauts examined the Russian sector units for damage regularly.

An air leak was detected in the Russian Zvezda module of the ISS, and the ISS can isolate the Zvezda module due to air leakage.

NASA and Roscosmos worked together to fix the leak, and the leak site was found by cosmonauts at the end of the previous month.

The Progress cargo ship was to deliver materials for the repair, and the first air leak was detected in September 2019.

A crack was detected in the Zvezda module camera in October 2020, and the ISS is a joint international project involving 14 countries.

The ISS has been operated from 1998 to the present, with a planned extension, and the Russian segment is controlled from the Space Flight Control Center.
