Is the ISS going to be a space hotel?

The air leak at the International Space Station was detected in August 2020 and temporarily fixed by cosmonauts in October 2020 using temporary means, but a permanent solution has not yet been fully implemented.

The International Space Station air leak was detected in August 2020 and was successfully fixed by cosmonauts in October of the same year using temporary means, including sealant.

The air leak at the International Space Station was detected in a spare radiator on a Russian Nauka module, prompting NASA to reschedule a spacewalk and postpone another.

Title:

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.

Content: NASA flight controllers decided to postpone two spacewalks while they were reviewing data regarding the recent coolant leak on the Russian side of the International Space Station (ISS).
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.

According to Roscosmos, in the Zvezda module, the smoke sensor triggered and the alarm system turned on during automatic recharging of batteries.
The crew included an aggregate filter for cleaning the atmosphere to eliminate “possible smoke, ” Roscosmos writes.
At the same time, the Russian propaganda resource RIA writes with reference to the broadcast of NASA negotiations: cosmonaut Oleg Novitsky reported to the Russian Mission Control Center that the crew saw smoke and felt the smell of burning.
It is noted that the devices showed the presence of harmful substances near the medical cabinet in the module Star, and ESA astronaut Tom Pesquet said that the smell of burnt plastic and electronics penetrated through ventilation into the American module.
Roscosmos claims that now all systems are working as normal, the composition of the air on the ISS corresponds to the standard indicators, and the crew continues to prepare for the spacewalk.

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.

Content: Russia to send rescue vehicle to International Space Station after leak
MOSCOW (AFP) - Russia said on Wednesday it will send a rescue vehicle to the International Space Station on February 20 to return three crew members of a Soyuz spacecraft damaged by a leak last month.
Announcement
The Soyuz MS-22 spacecraft, currently docked on the International Space Station, experienced a massive coolant leak in mid-December, and images showed quantities of particles leaking into space from the rear of the Russian spacecraft.
After examining the state of the device, the Russian space agency Roscosmos announced Wednesday that it considered it best to send another spacecraft, Soyuz MS-23, to bring back Russian cosmonauts Sergey Prokopiev and Dmitry Bitlin, as well as American astronaut Frank Rubio.
"It was decided to send the Soyuz MS-23 spacecraft on February 20, 2023 without passengers," Roscosmos said in a statement, but with the necessary equipment.
The spacecraft was initially scheduled to take off on March 16 to take three more astronauts to the International Space Station.
Joel Montalpano, director of the International Space Station program at NASA ’ s Johnson Space Center in Houston, said, “We don ’ t call this Soyuz a backup, ” but a“ replacement. ”
"For now, the crew is safe on board."
The return of the Russian and American pilots, initially scheduled for March 28, has not been announced.
But their mission will be extended "by several months," Roskosmos manned flight director Sergei Krikalyov told a news conference.
The damaged vehicle will return to Earth empty, possibly “in mid-March or at the end of March, ” Krikalyov said.
Emergency Scenarios
Pending the arrival of the replacement vehicle, and in the event of an emergency that necessitates the evacuation of the International Space Station, the Russian and US space agencies are considering several scenarios.
But both agencies said that possibility was still remote.
The first scenario is to bring the three crew members aboard the damaged Soyuz spacecraft, despite concerns about the temperature that can be reached inside the spacecraft at the time of landing.
The second scenario is to reduce the "convection" on board Soyuz by "reducing the size of the crew".
After that, one of the three passengers will be returned by a SpaceX spacecraft that is also currently anchored on the International Space Station.
In fact, in addition to the three crew members who came aboard Soyuz, the ISS currently has four other passengers who arrived aboard SpaceX ’ s Dragon spacecraft, which is also supposed to be used to bring them back.
The idea, therefore, is to secure a fifth person on board, “in the area where the cargo would normally be, ” explained Joel Montalpano, head of NASA ’ s International Space Station program.
Accurate meteor impact.
The leak was detected on 14 December aboard the Soyuz spacecraft, as the two Russian cosmonauts were about to exit the station into space.
A preliminary assessment of the causes of the coolant leakage attributed the event to the possibility of a naturally occurring small meteorite impact, man-made debris in orbit or hardware failure.
On Wednesday, Roskomos confirmed that the hypothesis of the impact of a micrometeorite was "experimentally proven".
According to the Russian agency, a hole "less than a millimeter in diameter" was opened in a cooling pipe.
Given the speed at which experts believe the object collided with the International Space Station, it could have been caused by a "meteorite that came from a random direction", not a piece of debris that "wouldn't have been able to stay in orbit" so quickly, according to Sergei Krikalyov.
The Russian agency ruled out any mechanical failure.
For Vitaly Egorov, a Russian specialist on space issues, the decisions announced by the Russian space agency Roscosmos on Wednesday "are ideal to ensure the safety of (the crew) and minimize damage to the space program."
The ISS is one of the few remaining areas of cooperation between Moscow and Washington since the start of the Russian invasion of Ukraine on February 24 and subsequent Western sanctions.
Roskosmos President Yuri Borisov last month praised the solidarity of Americans aboard the International Space Station, who have "extended a helping hand to help us" at a time when relations between the Kremlin and the White House were at an all-time low.
The International Space Station was launched in 1998 in a phase of U.S.-Russian cooperation, following the space race the two countries engaged in during the Cold War.
But the project has faced many technical problems, as well as corruption scandals that have tarnished the reputation of the Russian space industry in recent years, as it competed with the United States in the space race.

"The International Space Station experienced an air leak, detected on December 15, which might have been caused by a meteorite impact, software glitches, or deliberate sabotage. The leak originated from the Russian segment, possibly from the Zvezda or Nauka module."

In “Roscosmos ” called the hit of a micrometeoroid in the ship on the ISS unlikely event
The impact of a micrometeoroid on a ship docked to the International Space Station (ISS) is a very unlikely event.
This was announced by the executive director of the state corporation “Roscosmos ” for manned space programs Sergey Krikalev, reports TASS.
“This is really a very unlikely situation, because this micrometeorite did not just get into the ship and not just into the radiator, but got into the tube on this radiator, ” he said, referring to the situation on the damaged manned Soyuz MS-22 spacecraft.
Krikalev noted that in the investigation of the causes of the incident, the use of the manipulator of the American segment of the ISS helped.
The inspection made it clear that the ship had damaged the micrometeoroid.
Earlier, the General designer of the Rocket and Space Corporation (RSC) Energia Vladimir Solovyov said that the Soyuz MS-22 will return to Earth in unmanned mode at the end of March.
In the same month, Roscosmos for the first time showed photos of the damaged Soyuz MS-22, demonstrating a violation of the outer skin of the ship.
The leak in the thermal control system of Soyuz MS-22 was recorded on December 15.

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 air leak at the International Space Station was detected in a spare radiator on a Russian Nauka module, prompting NASA to reschedule a spacewalk and postpone another.

Title:

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.

According to Roscosmos, in the Zvezda module, the smoke sensor triggered and the alarm system turned on during automatic recharging of batteries.
The crew included an aggregate filter for cleaning the atmosphere to eliminate “possible smoke, ” Roscosmos writes.
At the same time, the Russian propaganda resource RIA writes with reference to the broadcast of NASA negotiations: cosmonaut Oleg Novitsky reported to the Russian Mission Control Center that the crew saw smoke and felt the smell of burning.
It is noted that the devices showed the presence of harmful substances near the medical cabinet in the module Star, and ESA astronaut Tom Pesquet said that the smell of burnt plastic and electronics penetrated through ventilation into the American module.
Roscosmos claims that now all systems are working as normal, the composition of the air on the ISS corresponds to the standard indicators, and the crew continues to prepare for the spacewalk.

The air leak at the International Space Station did not pose a threat to the crew, as it occurred outside the station and not inside the orbiting lab.

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 leak at the International Space Station did not pose a danger to the crew.

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 leak of external coolant from the International Space Station's Russian Nauka module was detected, but it did not pose a threat to the crew or the station. The leak was non-toxic, and NASA took precautions to prevent equipment degradation.

"The leak did not pose a threat to the crew and the International Space Station, but the cause of the recent leak remains unclear. Previous leaks have occurred on the International Space Station, including one that resulted in a six-month extension of the stay of NASA astronauts and two Russian cosmonauts."

The Nauka module was launched in 2021.

Content: NASA flight controllers decided to postpone two spacewalks while they were reviewing data regarding the recent coolant leak on the Russian side of the International Space Station (ISS).
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.

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.

An air leak was detected at the International Space Station about a week before a Progress launch and docking, with the volume of lost air increasing to about two pounds a day. The hatch in the affected area is closed, and the next opening is expected in April.

The International Space Station experienced an air leak in 2018, initially thought to be caused by a micrometeorite, but later found to be the result of deliberate sabotage.

"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 air leak at the International Space Station was reported by Roscosmos, the Russian space agency. Although the cause and fix are not explicitly stated, voids found in the portholes on the Russian segment could be related to the leak.

The air leak at the International Space Station was reported by Roscosmos, the Russian space agency, and was detected in August 2020 in the Zvezda module. The leak was repaired with temporary means in October of the same year.

A massive coolant leak occurred in the Soyuz MS-22 spacecraft docked at the International Space Station in mid-December, prompting Russia to send a rescue vehicle to return the crew members.

The air leak at the International Space Station was detected on December 14 and was reported by Roscosmos, the Russian space agency. The leak was likely caused by a micrometeorite impact, which was confirmed by Roscosmos.

The air leak at the International Space Station was reported by Roscosmos, the Russian space agency, and was likely caused by a micrometeoroid impact that damaged the Soyuz MS-22 spacecraft.

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.

The air leak at the International Space Station did not affect the astronauts' safety.

The air leak on the International Space Station, detected on September 10, did not affect the astronauts' safety as it stopped on the same day and there is no reported harm or risk to the astronauts.

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 leak at the International Space Station did not pose a threat to the astronauts' safety because the coolant involved is non-toxic and harmless to the crew.

The air leak at the International Space Station did not affect the astronauts' safety.

The air leak at the International Space Station decreased three times after the repair, which involved sealing the cracks.

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 leak on the International Space Station was detected in August 2020, and cosmonauts were able to find and repair the crack with temporary means in October of the same year, resulting in a three-fold reduction of the leak.

The air leak at the International Space Station was detected in August last year and was likely caused by cracks in one of the modules. After the crack was closed, the air leak decreased three times.

Details of the launch of the smoke alarm at the International Space Station
Smoke alarms went off in the Russian part of the International Space Station in the early hours of Thursday, and the crew reported noticing smoke and the smell of burning plastic.
According to the Associated Press, the Russian Federal Space Agency (Roscosmos) said that the accident occurred in the Russian Zvezda unit, and occurred during the recharging of the station's batteries.
According to Roscosmos, the crew activated the air filters and returned to night rest once air quality returned to normal.
The crew will continue to travel in space on Thursday, as planned.
The space station is currently operated by NASA astronauts Mark Vandy He, Shane Kimbro and Megan MacArthur.

The air leak at the International Space Station was reduced after repair work was carried out, with the rate of air leakage decreasing from 1.14 kg per day to 0.47 kg per day on a permanent basis and 0.3 kg per day on a temporary basis.

The crew of the International Space Station was not in danger due to the air leak in the Soyuz MS-22 spacecraft, as all systems were operating normally.

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.

NASA has aborted a scheduled spacewalk on the International Space Station following a water leakage incident involving astronaut Tracy Dyson's spacesuit.

Dyson, along with fellow astronaut Mike Barratt, was preparing for the mission when water began leaking from her suit's cooling system upon switching to battery power. Although the astronauts had not yet exited the station, Barratt reported significant water presence.

Despite the incident, NASA confirmed the astronauts were never in danger. The mission tasks included removing a faulty communications box and collecting microbe samples, but the spacewalk lasted only thirty minutes compared to the planned seven hours.

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.
