Zitat Russia says it will take no immediate action on damaged Soyuz spacecraft
After working through the weekend to better characterize damage to its Soyuz spacecraft attached to the International Space Station, Russian specialists have decided to take no immediate action.
In a lengthy statement published Monday morning by Roscosmos (a VPN is required to access the site from Western nations), the Russian space corporation said it believed that a tiny piece of debris ruptured an external cooling loop that radiates heat from inside the Soyuz into space.
Working with NASA on Sunday to operate the long Canadarm2 manipulator arm, Russian specialists were able to get a clear look at the damaged area on the aft end of the Soyuz spacecraft. The area of the hole is about 0.8 mm across, which, although small, allowed all of the coolant in the external loop to be dumped into space last Wednesday. Importantly, the visual inspection discovered no other notable damage to the Soyuz vehicle from the debris strike.
Speaking to Russian media on Monday, the director general of Roscosmos said working groups of specialists would spend about another week assessing the issue. A decision on future actions will be taken on December 27, Yuri Borisov said. At this point, there are two options under consideration: flying three crew members back to Earth inside Soyuz MS-22 or autonomously flying the next Soyuz in line, Soyuz MS-23, up to the station for the return flight. This Soyuz could be ready for flight as early as February 19.
The crew of Soyuz MS-22, cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA's Frank Rubio, launched to the space station in September. They had been due to return to Earth in March before the dramatic coolant leak, which has now delayed two spacewalks on board the International Space Station as astronauts work with ground controllers to assess the damage to the Soyuz.
Without a functional external radiator, there are concerns about the interior of the Soyuz spacecraft overheating. This could damage sensitive flight computers, necessitating a manual reentry into Earth's atmosphere. Much of the work over the next week will likely be conducted to understand how the spacecraft's internal temperature will change once it departs from the space station.
In reality, the Soyuz is a hardy spacecraft, built to withstand several failures. Certainly, Russian officials will be keen to use the existing spacecraft to fly home if at all possible. This is because there will be a substantial financial cost if the Soyuz MS-23 spacecraft, which was due to ferry three new passengers to the station in March, must be repurposed for this return flight.
Because Rubio is one of the three crew members slated to fly home, NASA is also closely scrutinizing the data. To date, the agency has offered limited public comment on the issue, preferring to give Russian specialists time to work on the problem and make recommendations on next steps.

Zitat The International Space Station conducted a Pre-Determined Debris Avoidance Maneuver (PDAM) today, Dec. 21, at 8:42 a.m. EST. The decision to conduct the maneuver was based on tracking data that showed a close approach to station of a fragment of Russian Fregat-SB upper stage debris.
During the manuever, the Roscosmos Progress 81 thrusters fired for 10 minutes, 21 seconds to provide the complex an extra measure of distance away from the predicted track of the debris. Without the maneuver, it was estimated that the debris could have passed less than a quarter of a mile from the station.
The decision to conduct the maneuver earlier this morning resulted in a postponement of today’s planned spacewalk by NASA astronauts Frank Rubio and Josh Cassada. The crew was never in any immediate danger.
Zitat Chris Bergin - NSF @NASASpaceflight NASA is planning to host a media teleconference on Thursday, Dec. 22, to discuss the ongoing investigation of the leak of the Soyuz MS-22 spacecraft docked to the International Space Station.

Zitat WASHINGTON, Dec 28 (Reuters) - NASA is exploring whether SpaceX's Crew Dragon spacecraft can potentially offer an alternative ride home for some crew members of the International Space Station after a Russian capsule sprang a coolant leak while docked to the orbital lab.
NASA and Russia's space agency, Roscosmos, are investigating the cause of a punctured coolant line on an external radiator of Russia's Soyuz MS-22 spacecraft, which is supposed to return its crew of two cosmonauts and one U.S. astronaut to Earth early next year.
If Russia cannot launch another Soyuz ship, or decides for some reason that doing so would be too risky, NASA is weighing another option.
"We have asked SpaceX a few questions on their capability to return additional crew members on Dragon if necessary, but that is not our prime focus at this time," NASA spokeswoman Sandra Jones said in a statement to Reuters.
Finding what caused the leak could factor into decisions about the best way to return the crew members. A meteroid-caused puncture, a strike from a piece of space debris or a hardware failure on the Soyuz capsule itself are three possible causes of the leak that NASA and Roscosmos are investigating.
A hardware malfunction could raise additional questions for Roscosmos about the integrity of other Soyuz vehicles, such as the one it might send for the crew's rescue, said Mike Suffredini, who led NASA's ISS program for a decade until 2015.
"I can assure you that's something they're looking at, to see what's back there and whether there's a concern for it," he said. "The thing about the Russians is they're really good at not talking about what they're doing, but they're very thorough."
Roscosmos chief Yuri Borisov had previously said engineers would decide by Tuesday how to return the crew to Earth, but the agency said that day it would make the decision in January. ... A recent meteor shower initially seemed to raise the odds of a micrometeoroid strike as the culprit, but the leak was facing the wrong way for that to be the case, NASA's ISS program manager Joel Montalbano told reporters last week, though a space rock could have come from another direction.
And if a piece of space debris is to blame, it could fuel concerns of an increasingly messy orbital environment and raise questions about whether such vital equipment as the spacecraft's coolant line should have been protected by debris shielding, as other parts of the MS-22 spacecraft are.

Zitat von The Launch Pad networkBREAKING! Crew Rescue Missions Scheduled Following MS-22 Leak - Written By: Zac - Published: Sun, Jan 8, 2023 9:31 PM Latest Update: Mon, Jan 9, 2023 5:01 PM
This is a developing story and mission details may change - Stay tuned for more updates
NASA and Roscosmos have officially declared Soyuz MS-22 not safe to fly for crew and a rescue strategy has been developed with an Official Statement from NASA and Roscosmos Expected on January 11th
The Solution
Soyuz MS-22 The damaged Soyuz MS-22 spacecraft will undock from the ISS in an unmanned mode and attempt to return home. Because the thermoregulation system is damaged, re-entry and landing may not be successful.
Soyuz MS-23 Russia's next mission Soyuz MS-23 was scheduled to launch with 3 Russian Cosmonauts in March but teams on the ground have been working around the clock to move the launch up to middle of February. Once ready for launch, a solo Russian Cosmonaut Oleg Kononenko will fly the Soyuz MS-23 spacecraft to the ISS. This will be the first solo spacecraft mission since 2004 when Brian Binney flew SpaceShipOne on its test flight.
Cosmonauts Sergey Prokopiev and Dmitry Petelin The 2 Russian Cosmonauts who have been stranded on the ISS due to the Soyuz MS-22 leak will stay on staton with Cosmonaut Oleg Kononenko for the duration of the MS-23 mission (6 months) before they return home together.
NASA SpaceX Crew 6 America's next mission NASA SpaceX Crew 6 is scheduled to launch mid February. Crew 6 was to be a crew of 2 NASA Astronauts, 1 UAE Astronaut and 1 Cosmonaut. Due to the situation on the ISS Russian Cosmonaut Andrey Fedyaev has been removed from the mission and will await re-assignment. Crew 6 will fly an an empty SpaceX pressure suit for American Astronaut Francisco Rubio to use.
Safety is the number one priority in space, that is why Russia is moving Soyuz MS-23 up, and changes are being made to NASA SpaceX Crew 6 but this will have an impact on the future schedule of the ISS.
The Soyuz spacecraft is only able to stay on orbit for 6 months, so with Soyuz MS-23 going up a month early, the entire Russian ISS schedule will now have to shift forward by approx. 1 month as the ISS must always have 1 American and 1 Russian onboard. Soyuz MS-23 can not depart the ISS until Soyuz MS-24 or NASA SpaceX Crew 7 (if Russian Cosmonaut Andrey Fedyaev is re-assigned to Crew 7) arrive at the ISS.
Crew 6 was already scheduled to launch in February, so the only major impact to the US program is that an agreement was made to fly a Russian Cosmonaut on Crew 6 and now that Cosmonaut will need to be re-assigned to a future mission.
Zitat Anatoly Zak@RussianSpaceWeb FINAL DECISION: #Soyuz MS-22 to land empty, Soyuz MS-23 to launch unmanned to recover stranded crew from #ISS: https://russianspaceweb.com/soyuz-ms-22.ht
New launch date (for now unpiloted) Soyuz MS-23 spacecraft is February 20
Roskosmos chief said NASA reps, who participated in the Chief Designer council meeting yesterday, had agreed to the plan to recover the Soyuz MS-22 crew with Soyuz MS-23 12:04 PM · Jan 11, 2023
Zitat On Jan. 8, 2023, Roskosmos promised to make a decision on the situation with the Soyuz MS-22 spacecraft on January 11, TASS reported. According to unofficial reports, the damaged ship would return to Earth without crew, while the Soyuz MS-23 spacecraft would be launched in February 2023 piloted by a single cosmonaut Oleg Kononenko. His crew mates Nikolai Chub and Andrei Fedyaev would remain on the ground to free return seats for the two Russian members of the stranded Soyuz MS-22 crew. NASA astronaut Frank Rubio, who also traveled to the ISS on Soyuz MS-22, would return to Earth aboard a US Dragon vehicle, according to that scenario.
On Jan. 9, 2023, Roskosmos denied that such a plan had been approved. According to other sources, several options were reviewed at the meeting of the Chief Designer Council on Jan. 10, 2023, and the preferred scenario was approved by the State Commission chaired by Roskosmos head Yuri Borisov the following day.
On January 11, Roskosmos released a video statement from Borisov announcing that the approved plan had called for launching Soyuz MS-23 on Feb. 20, 2023, in fully automated mode for the eventual return of all three members of the Soyuz MS-22 crew after an extended flight. The damaged Soyuz MS-22 would land empty, because it was ruled unfit for carrying the crew "based on the analysis of the ship's condition, thermal simulations and technical documentation," according to the official statement by Borisov. Soyuz MS-22 would be used for landing with the crew only under "especially critical circumstances aboard the ISS and upon a separate decision of the State Commission," Borisov said.
According to Borisov, NASA representatives, who participated in the Chief Designer council meeting at RKK Energia on January 10, had agreed with the plan and had committed to supporting it.
Borisov confirmed that the scenario involving launching Soyuz MS-23 with a solo pilot had been evaluated but rejected because of the time required to configure the vehicle for such a flight mode, to prepare necessary documentation and to train the pilot, which would delay the launch until the early March. However on its way to the station, Soyuz MS-23 would be used for cargo delivery.
Borisov also stated that the investigation into the failure of the radiator aboard Soyuz MS-22 had concluded that a meteor strike had caused the breach. According to calculations, a hole in the instrument compartment of the spacecraft, observed with a camera of the American ISS Segment, could be caused by a one-millimeter particle striking the vehicle with a speed of around 7,000 meters per second. Borisov also said that a possibility of a manufacturing defect in the radiator system of Soyuz MS-22 had also been evaluated but had not been confirmed.
Zitat Katya Pavlushchenko @katlinegrey Aaaaand... the second round! Rumors say, a leak appeared in the #ProgressMS21 which should be deorbited on February 18. The situation, according to the former head of Roscosmos PR service Dmitry Strugovets, is quite similar to the accident with Soyuz MS-22. 1:46 PM · Feb 11, 2023
1. There is a leak in the external radiator cooling loop of #ProgressMS21. 2. The hatch to the ship has been immediately closed. 3. The crew is in no danger. 4. RSC Energia calls a meeting to decide what to do next. 5. The launch of Soyuz MS-23 will be postponed.
And now there is a reason to believe that the cause of the #SoyuzMS22 accident was not a micrometeorite.
The hull of the Progress MS-21 cargo ship suffered unexpected depressurization on Saturday, Russian space agency Roscosmos said
MOSCOW (UrduPoint News / Sputnik - 11th February, 2023) The hull of the Progress MS-21 cargo ship suffered unexpected depressurization on Saturday, Russian space agency Roscosmos said.
"The contour of the Progress MS-21 transport cargo ship, deorbitation of which is scheduled for February 18, was depressurized, as confirmed by the telemetry data of the mission control center," the agency said in a statement.
The reasons for the depressurization are yet to be established, the statement read.
"The passage hatch of the ship is closed, thus Progress MS-21 is isolated from the general space of the ISS.
The temperature regime and pressure on board the station are normal, nothing is threatening the life and health of the crew, they feel good," Roscosmos added.
All cargo scheduled for deorbitation has already been loaded onto the Progress MS-21 spacecraft, according to the statement.
The incident had no effect on today's docking of the Progress MS-22 cargo spacecraft with the ISS, and will not affect the future manned flight program, the statement read. Progress MS-22 will be deorbited on February 18, as scheduled, Roscosmos said.

Nachtrag.
Zitat Jonathan McDowell@planet4589 Progress MS-21 is leaking, but there is some confusion about whether it's in the cooling radiator or the cargo compartment. So let's be cautious until we get more official info. 4:11 PM · Feb 11, 2023
Zitat David Sundström@DaveS_orbiter Replying to @planet4589 Leak is in the forward pressurized cargo compartment, not the SOK radiator of the PAO (instrument/propulsion section) like on Soyuz MS-22. That's why the hatches were closed. So it's actually cabin atmosphere that's being vented, not coolant. 4:04 PM · Feb 11, 2023

"Les hommes seront toujours fous; et ceux qui croient les guérir sont les plus fous de la bande." - Voltaire
Roscosmos said Saturday the Progress incident "will have no impact on the future station program." This is likely true for Progress MS-21, at least. The spacecraft already has been packed with trash and other material to be removed from the station, and was due to leave next week, burning up in Earth's atmosphere during reentry.
However, it seems too early to make such a conclusion for future missions. A critical question is what caused the depressurization event observed Saturday. It seems improbable that a second micrometeorite would have struck as second Russian spacecraft in less than two months. This raises doubts about whether the Soyuz MS-22 failure was indeed a micrometeorite issue—Russia has never released images of the impact site—and instead perhaps a manufacturing defect.
A few hours after the Progress depressurization Saturday there are more questions than answers, but none of this will comfort NASA as it partners with Russia to continue operating the space station. This latest Soyuz and Progress failures are just two in a long line of recent issues, including the Nauka module's misfiring thrusters in 2021, a Soyuz booster failure in 2018 that forced Aleksey Ovchinin and Nick Hague to make an emergency return to Earth, or another leaky Soyuz vehicle.
These are the kinds of problems that one might expect from a space industry in Russia that is reliant on aging infrastructure, aging technology, and quality control issues due to inadequate budgets.
Zitat International Space Station Operations Update, Crew Continues Normal Activities
Earlier today, Feb. 11, the uncrewed Roscosmos Progress 83 cargo spacecraft docked automatically to the aft end of the Zvezda service module at the International Space Station. The rendezvous and docking operations were conducted with no issues.
Meanwhile, engineers at the Russian Mission Control Center outside Moscow recorded a depressurization in the unpiloted Roscosmos Progress 82 cargo ship’s coolant loop, which is docked to the space-facing Poisk module at the station. Progress 82, which arrived to the space station in October 2022, is scheduled to undock Friday, Feb. 17, filled with trash and will be deorbited over the Pacific Ocean.
The reason for the loss of coolant in the Progress 82 spacecraft is being investigated. The hatches between the Progress 82 and the station are open, and temperatures and pressures aboard the station are all normal. The crew, which was informed of the cooling loop leak, is in no danger and continuing with normal space station operations.
Nota bene: die NASA ist hier noch auf dem Stand der ersten Pressemeldung von Roskosmos, in der von einem "Leck im Kühlsystem" die Rede war. Mitlerweile ist offiziell, daß es zu einem Druckabfal in der Kapsel selbst gekommen ist und die Luken geschlossen worden sind.

Zitat Anatoly Zak @RussianSpaceWeb Leak from Progress MS-21 appears to be less extensive than a similar loss of coolant on #Souyz MS-22 in December, but it seemingly originated from the same area of a radiator. UPDATES: https://russianspaceweb.com/progress-ms-21 7:26 PM · Feb 11, 2023
Zitat On February 11, Roskosmos, citing data from mission control, said that the Progress MS-21 cargo ship docked at the station had lost pressure. According to the State Corporation, the hatch connecting the ship's pressurized compartment with the rest of the station was closed and the vehicle was fully isolated from the ISS' habitable volume.
Roskosmos added that the reasons for the depressurization were being evaluated and the incident would not affect the subsequent ISS flight manifest and stressed that the temperature and pressure inside the station was normal.
According to unofficial sources, the spacecraft lost all its cooling fluid from its Thermal Control System, SOTR. (INSIDER CONTENT) Several hours after the incident, NASA confirmed that the breach had been limited to the cooling system. At the same time, the US space agency said that the hatches between the cargo ship and the station had remained open, while temperatures and pressures aboard the outpost had stayed normal.
The accident apparently took place just half an hour after docking of the fresh Progress MS-22 cargo ship at a different docking port of the Russian Segment and resembled the situation with the Soyuz MS-22 crew vehicle in December 2022.
The subsequent publicly available exchange between the NASA mission control in Houston and a US astronaut Frank Rubio, aboard the ISS, indicated that the coolant system of the Progress MS-21 spacecraft had been completely emptied before the leak stopped. NASA also indicated that the plans to undock the vehicle from the ISS according to its original schedule had remained in place for the time being but could be a subject to change.
Prior to the coolant leak, Progress MS-21 was scheduled to undock from the zenith (skyward facing) port of the Poisk module, MIM2, on Feb. 18, 2023, at 03:55:30 Moscow Time (7:55 p.m. EST on Feb. 17) to make way for the arrival of the unpiloted Soyuz MS-23 spacecraft replacing the damaged Soyuz MS-22.
The spent cargo ship was expected to be deorbited on Feb. 18, 2023, at around 07:05 Moscow Time over a remote region of the Pacific Ocean. Any surviving debris were estimated to hit the ocean surface at around 07:45 Moscow Time.
According to Dmitry Strugovets, a former Roskosmos spokesman, an emergency meeting at RKK Energia, held on February 11, established that the leak had started after 09:40 UTC on February 11 (4:40 a.m. EST) and the Russian specialists planned to request an inspection of the damaged Progress with the Canadarm, despite less than ideal vantage points available to the robotic arm for observing this particular area of the station.
Wie erwartet. Nach der neuen Leckage am Progress-Frachtransporter hat Roskosmos heute den Start von Sojus MS-23 vom geplanten Termin am 20. Februar auf die erste Hälfte des März verschoben. (Sie schreiben "erste Dekade"/erste 10 Tage). Wedomosti gerade:

Zitat On Feb. 17, the uncrewed Roscosmos Progress 82 cargo spacecraft undocked without issue from the International Space Station’s Poisk module at 9:26 p.m. EST. Following undocking, Expedition 68 cosmonauts Sergey Prokopyev and Dmitri Petelin sent commands from the station’s Roscosmos segment to rotate the Progress for additional visual inspections using space station’s external cameras of the general area where a coolant leak occurred on Feb. 11.
After Progress departure from the space station, flight controllers at Mission Control in Moscow canceled Friday’s scheduled deorbit burn while Roscosmos analyzed the post-undocking imagery collected of the Progress radiator.
Early Saturday, Roscosmos managers decided to deorbit Progress Saturday, Feb. 18, with a deorbit burn time of 10:15 p.m. EST. Progress remains in a stable configuration and on a safe trajectory well away from the International Space Station. Loaded with trash, Progress will deorbit over the Pacific Ocean after spending four months at the station.
Zitat The cargo vehicle was supposed to move a safe distance away from the space station and fire its engines for a de-orbit burn at 11:03 p.m. EST (0403 GMT), setting up for a re-entry into the atmosphere over the Pacific Ocean less than an hour later. But Roscosmos said on its Telegram channel that the de-orbit burn was postponed, and space agency managers will decide Saturday whether proceed with the destructive re-entry or return the Progress spacecraft to the International Space Station for further investigation into the coolant system malfunction.
“Two options are being considered: its docking to the Russian nodal module ‘Prichal’ for further clarification of the cause of the depressurization of the ship’s thermal control system, or de-orbiting,” Roscosmos said.

Erlaubt ist lediglich das Zitieren weniger Sätze oder kurzer Absätze aus einem durch Copyright geschützten Dokument; und dies nur dann, wenn diese Zitate in einen argumentativen Kontext eingebunden sind.

Links können zu einzelnen Artikeln, Abbildungen oder Beiträgen gesetzt werden, aber nicht zur Homepage von Foren, Zeitschriften usw. Bei einem Verstoß wird der betreffende Beitrag gelöscht oder redigiert. Bei einem massiven oder bei wiederholtem Verstoß endet die Mitgliedschaft. Eigene Beiträge dürfen nachträglich in Bezug auf Tippfehler oder stilistisch überarbeitet, aber nicht in ihrer Substanz verändert oder gelöscht werden. Nachträgliche Zusätze, die über derartige orthographische oder stilistische Korrekturen hinausgehen, müssen durch "Edit", "Nachtrag" o.ä. gekennzeichnet werden.
