Roscosmos said that the causes of microcracks on the ISS are not yet known
Photo: telegram channel "State Corporation" Roscosmos "
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.

The International Space Station air leak was detected in August last year and was fixed after a while, although the exact details of the repair are not provided.

NASA and Roscosmos are investigating the cause of the air leak on the International Space Station.

Title:

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.

Content: Russian space station laboratory module appears to spring coolant leak

An apparent exterior coolant leak from a Russian laboratory module at the International Space Station has been reported by the crew. It follows similar leaks that struck a Russian Soyuz crew ferry craft and a Progress cargo ship within the past year.

This latest incident was reported by Mission Control Center at NASA’s Johnson Space Center in Houston to NASA space station crew member Jasmin Moghbeli around 1 p.m. EDT (1700 UTC).

“We’re seeing flakes outside. Need a crew to go to the cupola, look toward the aft side, we think windows five or six, and confirm any visual flakes,” mission control requested.

Moghbeli, the commander of the SpaceX Crew-7 mission and current ISS flight engineer, said she would go check it out herself. She was asked if she could confirm the point of origin, since it was difficult to see that from the ground perspective.

“Yeah, there’s a leak coming from the radiator on the MLM,” Moghbeli said.

The MLM is the Multipurpose Laboratory Module, also called “Nauka.” It’s the newest module of the space station, having launched on a Russian Proton rocket on July 21, 2021.

“We copy and we think we concur. We just confirmed it with video and they’re seeing it here on the ground,” Mission Control replied. “Jaws [a nickname for Moghbeli], can you please close the cupola shutters?”

Less than a minute later, Moghbeli confirmed the shutters were closed. This was presumably to prevent the surface of the windows being contaminated by the leaking coolant. About 20 minutes after that, ISS Commander and European Space Agency (ESA) astronaut Andreas Mogensen confirmed to Mission Control that the gym and lab shutters on the U.S. side of the space station were also closed.

NASA has not yet made an official comment regarding the leak.

This is a developing story. Check back for updates.

The air leak at the International Space Station was reported and is being investigated by NASA and Roscosmos, with Roscosmos scheduling a spacewalk to examine a potential source of the leak.

New problems have been identified in the Russian segment of the International Space Station.
They were discovered by cosmonauts Anton Shkaplerov and Pyotr Dubrov, Roscosmos CEO Dmitry Rogozin said.
“I already know, I know that you seem to have found some problems, and you know how to cure them, ” the head of the state corporation said during a conversation with members of the ISS crew.
Rogozin expressed hope that the astronauts will be able to eliminate the problems on the station.
Recall that in March of this year, Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov carried out repairs on the housing of the Zvezda module, where a crack and several possible places of leakage were found.
Later, cosmonaut Ivan Wagner said that air leakage after sealing the cracks decreased three times.
Astronaut Pavel Vinogradov told kp.ru about the main causes of cracks in the body of the ISS.

The air leak on the International Space Station was first detected in 2019, and the necessary equipment to fix it will be delivered by Progress.

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.

The air leak at the International Space Station occurred outside the station.

Title:

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.

Content: NASA was forced to change the date of the upcoming spacewalk and postpone another spacewalk due to a leak of external coolant from the International Space Station (ISS).
The leak originated from a spare radiator on a Russian Nauka module.
While the coolant is non-toxic or harmless to crew members, NASA is taking precautions to prevent it from entering the internal system and causing equipment degradation over time.
In view of this situation, the spacewalk scheduled for Thursday, 30 September, has been rescheduled.
The mission of the spacewalk program is not time-sensitive and will not affect the operation of the International Space Station.
The second spacewalk, which was originally scheduled to take place on Monday, October 10, will take place as planned.
This will mark the first time NASA astronauts Loral O'Hara and Jasmin Moghbeli have made the journey.
During the spacewalk, they will remove a faulty electronic box and replace the roller bearings on the port truss solar Alfa rotary joints, enabling the space station ’ s array of solar cells to track the sun.
Meanwhile, another spacewalk currently awaiting rescheduling will involve O'Hara and European Space Agency astronaut Andreas Morgensen.
Their mission included collecting samples from the outside of the space station to determine the presence of microbes.
They will also replace high-definition cameras and carry out maintenance work in preparation for future spacewalks.
This is not the first time that a refrigerant leak has affected the operation of the International Space Station.
Last year, the Soyuz spacecraft leaked coolant after being hit by a small meteor, resulting in a six-month extension of the stay of NASA astronauts and two Russian cosmonauts.
The cause of the recent leak of the Nauka module radiator remains unclear.

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.

Content: On the ISS found a place of possible air leakage in the module “Star ”
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.

Is the ISS going to be a space hotel?

The International Space Station air leak was detected in August last year and was fixed after a while, although the exact details of the repair are not provided.

The International Space Station air leak was fixed in March 2021 when cosmonauts covered two cracks with sealant in the Zvezda module.

The International Space Station air leak was fixed by sealing the cracks, which resulted in a three-fold decrease in air leakage.

New problems have been identified in the Russian segment of the International Space Station.
They were discovered by cosmonauts Anton Shkaplerov and Pyotr Dubrov, Roscosmos CEO Dmitry Rogozin said.
“I already know, I know that you seem to have found some problems, and you know how to cure them, ” the head of the state corporation said during a conversation with members of the ISS crew.
Rogozin expressed hope that the astronauts will be able to eliminate the problems on the station.
Recall that in March of this year, Russian cosmonauts Sergey Ryzhikov and Sergey Kud-Sverchkov carried out repairs on the housing of the Zvezda module, where a crack and several possible places of leakage were found.
Later, cosmonaut Ivan Wagner said that air leakage after sealing the cracks decreased three times.
Astronaut Pavel Vinogradov told kp.ru about the main causes of cracks in the body of the ISS.

The International Space Station air leak was detected in September 2020 and was fixed through repair efforts carried out in March 2021, which successfully localized and eliminated the damage to the shell and reduced the rate of air leakage.

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 International Space Station air leak was reportedly fixed after sealing cracks, with a decrease in air leakage noted in mid-April 2022.

NASA and Roscosmos are investigating the cause of the air leak on the International Space Station.

Russian cosmonauts discovered the possible location of the air leak in the Zvezda unit of the International Space Station in December, and NASA is considering isolating the module if necessary. The materials and equipment needed to repair the leak will be sent aboard a Progress cargo vehicle.

Russian space ship's coolant leak damaged by micrometeorite
A senior Russian aerospace official said today that a leak of coolant from Russia ’ s Soyuz spacecraft MS-22, docked at the International Space Station, lasted at least three hours last night, most likely caused by a subtle collision with a space object.
NASA and Roscosmos said the leak of coolant did not affect the safety of any astronauts, but the crew at the Moscow end of the mission could force control of the two astronauts to cancel their exit plans.
A live broadcast from the NASA website showed liquid coolant being sprayed out into space.
Sergei Krikalev, the head of the Russian Federal Space Agency ’ s manned space mission, said in a statement posted on social media on Telegram: “The cause of the leak on the Soyuz MS-22 may have been a micrometeoroid crashing into the spacecraft ’ s radiator. ”
Micrometeoroids or space rocks, mostly as small as grains of sand, are common in the space environment and travel through the Solar System in a random direction, often causing little or no substantial damage to the International Space Station or other space objects with advanced barrier protection.
NASA said the cause of the coolant leak is being investigated by the Russian side.
The coolant that regulated the temperature inside the space capsule was ejected from the cooling circuit of the external cooler of the Soyuz MS-22.
NASA said that the temperature of the Soyuz MS-22 "remains within acceptable limits" but neither NASA nor the Russian space agency have explained the Soyuz temperature range, how much temperature reaches the limit, how much coolant leaked or when the leak stopped.

Content: Cosmonauts' spacewalk canceled at space station due to leak

NASA and Russia's space agency canceled a spacewalk by two Russian cosmonauts just as they were preparing to exit the International Space Station late Wednesday because of an apparent coolant leak from an attached space capsule.

NASA's Johnson Space Center said Sergey Prokopyev and Dmitri Petelin were not in danger, nor were other astronauts on the space station. The cosmonauts had donned spacesuits and depressurized an airlock when the leak appeared on a live video feed.

It was the second time the Russian cosmonauts have had to cancel the spacewalk. As in the first attempt on Nov. 25, the pair had planned to move a radiator from one module attached to the space station to another. In that first attempt, a problem arose with coolant pumps on the cosmonauts' Russian-built Orlan spacesuits.

In Wednesday's incident, ground specialists saw a stream of fluid and particles on a live video feed from space, along with a pressure drop on instruments, emanating from the Soyuz MS-22 capsule that had carried Prokopyev and Petelin, along with NASA astronaut Frank Rubio, to the International Space Station in September. The leak was continuing from the Soyuz capsule, docked to one of the space station's modules, hours after its discovery.

The cosmonauts restored pressure to the airlock, removed their spacesuits and re-entered the space station, NASA reported.

Russia's space agency and NASA planned to investigate the Soyuz leak to determine how the capsule might have been affected. It wasn't immediately clear what effect the leak would have on the crew's mission.

Four other astronauts and one other cosmonaut are on board the space station.

NASA and Roscosmos are involved in addressing the air leak on the International Space Station, with Russian cosmonauts identifying a possible source of the leak in late December.

Content: NASA reported on the possible isolation of the module “Star ” on the ISS
The module of the International Space Station (ISS) “Star ” can be isolated forever if it is not possible to eliminate air leakage, reports“ Interfax ” with reference to NASA Director for the ISS program Robin Gatens.
“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.

A coolant leak occurred on the Russian portion of the International Space Station on September 10, which was stopped on the same day. The cause of the leak is still under investigation, and Roscosmos plans to conduct a spacewalk to scrutinize the suspected source of the leak.

The leak did not pose an immediate danger to the crew's health since the coolant is non-toxic, but experts are working to prevent potential equipment degradation over time.

A leak of external coolant from the International Space Station's Russian Nauka module was detected, but it did not pose a direct danger to the crew since the coolant is non-toxic.

A leak was detected in the reserve circuit of the radiator of the multi-purpose laboratory module 'Science' of the Russian segment of the ISS on October 9, but it did not pose a danger to the crew or the ISS.

From the external (backup), which was delivered to the station in 2012, there was a leak.
Roscosmos assured that the main thermal control circuit of the module works in normal mode, “provides comfortable conditions in the residential area of the module. ”
The crew and the ISS are not in danger.
"The work of the main operational group of the management to analyze the current situation continues," the state corporation added.
As reported by IA Regnum, the longest mission to the International Space Station ended in late September.
Russian cosmonauts Sergei Prokopyev, Dmitry Petelin and American astronaut Frank Rubio, having broken the record of staying on the ISS, landed on the descent vehicle of the Soyuz MS-23.
The station “Luna-25 ” crashed, according to the main version, because of the unit measuring angular velocities (BIUS-L), which got confused in the teams and sent the station zero speed signals, reported on October 3 in the press service of“ Roscosmos ”.

The leak did not pose an immediate danger to the crew and the International Space Station.

Content: Russian space station laboratory module appears to spring coolant leak

An apparent exterior coolant leak from a Russian laboratory module at the International Space Station has been reported by the crew. It follows similar leaks that struck a Russian Soyuz crew ferry craft and a Progress cargo ship within the past year.

This latest incident was reported by Mission Control Center at NASA’s Johnson Space Center in Houston to NASA space station crew member Jasmin Moghbeli around 1 p.m. EDT (1700 UTC).

“We’re seeing flakes outside. Need a crew to go to the cupola, look toward the aft side, we think windows five or six, and confirm any visual flakes,” mission control requested.

Moghbeli, the commander of the SpaceX Crew-7 mission and current ISS flight engineer, said she would go check it out herself. She was asked if she could confirm the point of origin, since it was difficult to see that from the ground perspective.

“Yeah, there’s a leak coming from the radiator on the MLM,” Moghbeli said.

The MLM is the Multipurpose Laboratory Module, also called “Nauka.” It’s the newest module of the space station, having launched on a Russian Proton rocket on July 21, 2021.

“We copy and we think we concur. We just confirmed it with video and they’re seeing it here on the ground,” Mission Control replied. “Jaws [a nickname for Moghbeli], can you please close the cupola shutters?”

Less than a minute later, Moghbeli confirmed the shutters were closed. This was presumably to prevent the surface of the windows being contaminated by the leaking coolant. About 20 minutes after that, ISS Commander and European Space Agency (ESA) astronaut Andreas Mogensen confirmed to Mission Control that the gym and lab shutters on the U.S. side of the space station were also closed.

NASA has not yet made an official comment regarding the leak.

This is a developing story. Check back for updates.

The Nauka module was launched in July 2021.

The first spacewalk, scheduled for October 12, and the second spacewalk scheduled for October 20, will be rescheduled later.
The coolant leak occurred on October 9 in the backup coolant of the Nauka multipurpose laboratory unit.
However, NASA confirmed that the main coolant at Nauca is still functioning properly and provides complete cooling to the unit without affecting the operations of the crew or the space station.
External camera views showed only the remaining coolant droplets.
The backup coolant was delivered to the ISS in 2010 on the Rassvet module during the STS-132 space shuttle mission.
It was intended for use with the Nauka module, which was launched in July 2021 and the component was installed in April of this year.
The Russian space agency Roscosmos plans to have astronauts take photos of the chiller during the next scheduled Russian spacewalk on October 25.
The goal is to determine the cause of the leak and determine whether it is possible to repair the device in the future.

The decision to delay spacewalks is a precautionary measure as NASA and Roscosmos investigate coolant leaks and ensure the safety of astronauts and the space station.
New spacewalks will be announced once the review process is complete.

The air leak at the International Space Station was reported and is being investigated by NASA and Roscosmos, with Roscosmos scheduling a spacewalk to examine a potential source of the leak.

The air leak at the International Space Station was reported by Roscosmos, after Russian cosmonauts Pyotr Dubrov and Anton Shkaplerov discovered the possible last place of air leakage in the Zvezda module.

Roscosmos reported an air leak at the International Space Station on October 9, which was detected in the reserve circuit of the radiator of the multi-purpose laboratory module 'Science' of the Russian segment of the ISS.

The organization that reported the air leak at the International Space Station is Roscosmos.

Russian cosmonauts discovered the possible location of an air leak in the Zvezda unit of the International Space Station, and the Roscosmos Foundation reported this discovery.

The air leak at the International Space Station was reported by Russian cosmonauts Pyotr Dubrov and Anton Shkaplerov, who discovered the presumed last place of air leakage in the Zvezda module.

The air leak at the International Space Station was reported by Russian cosmonauts Peter Dobrov and Anton Shkaplerov, who discovered the possible location of the leak in the Zvezda unit in December.

Cosmonaut Pyotr Dubrov reported a possible air leak at the International Space Station, which was discovered in the Zvezda module.

Russian cosmonauts Peter Dubrov and Anton Shkaplerov reported the air leak at the International Space Station in late December.

An air leak was detected at the International Space Station in August last year due to a crack in one of the modules. The crack was closed, which slowed down the pressure decrease.

An air leak was detected at the International Space Station on October 9, but it did not pose a danger to the crew or the station, as the main thermal control circuit was functioning normally.

The air leak at the International Space Station did not affect the main coolant loop, ensuring the crew's safety. The leak was isolated, and the crew followed safety protocols to mitigate potential risks.

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.

A coolant leak occurred on the Russian Soyuz spacecraft MS-22 docked at the International Space Station, likely caused by a micrometeorite collision, and although it did not affect astronaut safety, it led to the cancellation of exit plans.

An air leak was detected on the International Space Station due to the presence of harmful substances and a smell of burnt plastic and electronics. The cause might be related to voids found in the portholes on the Russian segment, but Roscosmos reports that the issue has been resolved and all systems are working normally.

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.

Leak of coolant occurred on the module "Science" of the Russian segment of the ISS
On the ISS there was a leak of coolant on the module "Science".
The problem occurred on the external circuit of the radiator, which was delivered to the station in 2012.
This was reported in Roscosmos.
The crew and the station were not in danger.
The main circuit of thermal control of the module operates in normal mode, providing comfortable conditions in the residential area, noted in the state corporation.

Russian officials said on Monday that coolant had leaked from a backup line at the International Space Station and that there was no danger to the crew or the site.
The Russian space agency Roscosmos reported that the coolant leaked from a backup external cooling device at the new Russian science laboratory, confirming that the laboratory's main thermal control system was "operating normally."

Roscosmos said: "There is no danger to the crew and the station."
While NASA confirmed there was no threat to the station's seven-member crew and operations were continuing as usual, Roscosmos said engineers were investigating the cause of the leak.
The accident comes on the heels of a coolant leak from a Russian spacecraft parked at the station recently.
Officials said small meteorites were the cause of such leaks, such as a leak of coolant from a Soyuz capsule that docked at the station in December, and another similar leak from the supply ship Progress was discovered in February.
A Russian investigation has concluded that the leaks may have been caused by the impact of small meteorites, not manufacturing defects.
The Soyuz capsule leak led to a lengthy stay for NASA astronaut Frank Rubio and his Russian colleagues, Sergei Prokopev and Dmitry Beitlin, who spent 371 days in orbit instead of six months.
A replacement capsule was sent to the station to bring back the astronauts.
The space station, which served as a symbol of international cooperation in the post-Cold War era, is now one of the remaining areas of cooperation between Russia and the West amid tensions over Moscow ’ s war in Ukraine.
NASA and its partners hope to continue operating the orbital station until 2030.

An air leak was detected at the International Space Station in August last year, and after closing the crack, the pressure decrease slowed down, but new non-through cracks were recently discovered in the ISS module.

The International Space Station experienced microcracks, which are being investigated, and repair work is underway, but the causes of the microcracks are still unknown.

An air leak occurred on the International Space Station on September 10, which was stopped the same day, and is currently under investigation by NASA and Roscosmos, with a spacewalk scheduled for May 13 to determine the cause.

The air leak on the International Space Station was detected in 2019 and is believed to have been caused by cracks in the hull. Russian cosmonauts have discovered the possible last place of air leakage and are waiting for equipment to be delivered to return the module to tightness.

The air leak at the International Space Station was detected by Russian cosmonauts, who found a possible place of leakage in the Zvezda module. The leak is expected to be fixed after the delivery of necessary equipment on the Progress cargo ship.

"The investigation into the radiator leak on the Nauka module is ongoing, with astronauts facing challenges in detecting the leak. They initially found no signs of leaks but later discovered traces near the radiator panel joints and a large amount of cooling liquid on a pipe at a radiator junction."

The air leak at the International Space Station was detected by cameras and confirmed by the crew, but the next steps to fix it have not been determined.

The air leak at the International Space Station was detected when the alarm system of the Soyuz MS-22 spacecraft's diagnostic system indicated a drop in pressure in the cooling system, which was then visually confirmed by the crew.

On the Soyuz MS-22 spacecraft, docked to the International Space Station (ISS), there was damage to the outer skin of the instrumentation compartment, the press service of Roscosmos reported.
“The crew reported the operation of the alarm system of the ship ’ s diagnostic system, indicating a drop in pressure in the cooling system.
The visual inspection confirmed the leak, after which it was decided to interrupt the planned work on extra-ship activities by the crew members of the Russian segment of the ISS Sergei Prokopyev and Dmitry Petelin, ” the statement said.
Astronaut Anna Kikina photographed and videographed the outer surface of the ship, experts on Earth began to study the images.
All the systems of the Soyuz and the ISS are operating normally, the crew is not threatened, Roscosmos stressed.
Because of the problem today again failed spacewalk cosmonauts Prokopiev and Petelin, who had to prepare the radiator to carry the manipulator ERA from the module "Dawn" and install it on the "Science".
These works Russian cosmonauts were originally to be held on November 25, but then the spacewalk was canceled due to the discovered abnormal operation of the pumps in the cooling system of one of the spacesuits.

The air leak at the International Space Station occurred outside the station.

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.

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.
