During spaceflight

Template:As of, there have been five incidents in which a spacecraft in flight suffered crew fatalities, killing a total of 15 astronauts and 4 cosmonauts.Template:SfnpTemplate:How Of these, two had reached the internationally recognized edge of space when or before the incident occurred, one had reached the U.S. definition of space at 266,000 ft, and one was planned to do so. In each of these accidents, the entire crew was killed. Template:As of, a total of 676 people have flown into space and 19 of them have died. This sets the current statistical fatality rate at 2.8 percent.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>Template:Update inline

NASA astronauts who died on duty are memorialized at the Space Mirror Memorial at the Kennedy Space Center Visitor Complex in Merritt Island, Florida. Cosmonauts who died on duty under the Soviet Union were generally honored by burial at the Kremlin Wall Necropolis in Moscow. No Soviet or Russian cosmonauts have died during spaceflight since 1971.

Template:Nowrap	Launch booster failure, vehicle disintegration during launch – Space Shuttle Challenger disaster	Template:Nowrap	Template:Nowrap Template:Nowrap Template:Nowrap Template:Nowrap Template:Nowrap Template:Nowrap Template:Nowrap	The Space Shuttle Challenger was destroyed 73 seconds after lift-off on STS-51-L at an altitude of Template:Convert. The investigation found that cold weather conditions caused an O-ring seal to fail, allowing hot gases from the shuttle's solid rocket booster (SRB) to impinge on the external propellant tank and booster strut. The strut and aft end of the tank failed, allowing the top of the SRB to rotate into the top of the tank and causing it to explode. Challenger was thrown sideways into the Mach 1.8 windstream and broke up with the loss of all seven crew members. NASA investigators determined they might have survived the spacecraft disintegration, possibly unconscious from hypoxia; some tried to activate their emergency oxygen. Any survivors of the breakup would have been killed, however, when the largely intact cockpit hit the water at 320 km/h (200 mph), about 32 km (20 miles) east of Cape Canaveral at 28.64 degrees north, 80.28 degrees west.<ref>"Shuttle explodes; crew lost", Frederick, OK – Daily Leader newspaper, 28 January 1986.</ref><ref>"Flight From Triumph to Tragedy Kills Challenger's 'Seven Heroes'", The Palm Beach Post, 29 January 1986.</ref> About half of the vehicle's remains were never recovered, and fragments still washed ashore as late as a decade later on the coast of Brevard County, Florida.<ref>Template:Cite news</ref>

Investigation revealed that a piece of foam insulation had fallen off the external tank and hit the shuttle during launch, damaging the reinforced carbon-carbon leading edge of the left wing and allowing the extreme heat of reentry to cause structural failure.<ref>"Space Shuttle debris rains across Texas", Ocala, FL Star Banner newspaper, 2 February 2003.</ref> The vehicle began to break up over California and fell in fragments over eastern Texas and central Louisiana.

During training or testing

In addition to accidents during spaceflights, 11 astronauts, test pilots, and other personnel have been killed during training or tests.

Non-fatal incidents during spaceflight

Apart from actual disasters, 39 missions resulted in some very near misses and also some training accidents that nearly resulted in deaths. Template:Sticky header

Incident	Date	Mission	Description
Separation failure	Template:Nowrap	Template:Nowrap	After retrofire, the Vostok service module unexpectedly remained attached to the reentry module by a bundle of wires. The two halves of the craft were supposed to separate ten seconds after retrofire. But they did not separate until 10 minutes after retrofire, when the wire bundle finally burned through. The spacecraft went into wild gyrations at the beginning of reentry, before the wires burned through and the reentry module settled into the proper reentry attitude.<ref name = "Vostok 1"> Template:Cite news </ref>
Landing capsule sank in water	Template:Nowrap	Mercury-Redstone 4	After splashdown in the Atlantic Ocean, the hatch malfunctioned and blew prematurely, filling the capsule with water and almost drowning Gus Grissom, who managed to escape before it sank. Grissom then had to deal with a spacesuit that was rapidly filling with water, but managed to get into the helicopter's retrieval collar and was lifted to safety.<ref name="Liberty Bell 7 Sinks"> Template:Cite news </ref> The spacecraft was recovered in 1999, having settled at the bottom of the Atlantic Ocean about Template:Convert southeast of Cape Canaveral at a depth of about Template:Convert.

Space suit or airlock design fault	Template:Nowrap	Template:Nowrap	The mission featured the world's first spacewalk, by Alexei Leonov. After his twelve minutes outside, Leonov's space suit inflated in the vacuum to the point where he could not reenter the airlock. He opened a valve to allow some of the suit's pressure to bleed off, and was barely able to get back inside the capsule after suffering side effects of the bends. Because the spacecraft was so cramped, the crew could not keep to their reentry schedule and landed Template:Cvt off course in deep forest. They spent a night sheltering in the capsule from the cold, and a second night in a temporary hut built by rescuers before skiing with them to a clearing where a helicopter flew them to Perm.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
Engine shutdown at launch	Template:Nowrap	Template:Nowrap	The first on-pad shutdown in the U.S. human spaceflight program. Gemini 7 orbiting Template:Convert directly over Missile Row witnessed the event and reported they could clearly see the momentary exhaust plume before shutdown.<ref name=Gemini6A_abort>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
Equipment failure	Template:Nowrap	Template:Nowrap	A maneuvering thruster refused to shut down and put their capsule into an uncontrolled spin.<ref name="Gemini 8 close call"> Template:Cite news </ref> After the Gemini spun up to one revolution per second, Neil Armstrong regained control by switching from the main attitude control system to the reentry system. Mission rules required a landing as soon as possible once the reentry thrusters were used, causing an early end to the flight.<ref name=nssdc1966>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
Separation failure	Template:Nowrap	Template:Nowrap	Harrowing reentry and landing when the capsule's service module initially refused to separate, causing the spacecraft to begin reentry faced the wrong way. The service module broke away before the capsule would have been destroyed, and so it made a rough but survivable landing far off course in the Ural Mountains.
Struck twice by lightning during launch	Template:Nowrap	Template:Nowrap	Two lightning strikes during launch. The first strike, at 36 seconds after liftoff, knocked the three fuel cells offline and the craft switched to battery power automatically. The second strike, at 52 seconds after liftoff, knocked the onboard guidance platform offline. Four temperature sensors on the outside of the Lunar Module were burnt out and four measuring devices in the reaction control system failed temporarily. Fuel cell power was restored about four minutes later. The astronauts spent additional time in Earth orbit to make sure the spacecraft was functional before firing their S-IVB third stage engine and departing for the Moon.<ref>"Apollo Hit Twice By Lightning", Salt Lake City, Utah – Deseret newspaper, 17 December 1969</ref><ref>"Apollo Struck Twice By Lightning", Hopkinsville, Kentucky – New Era newspaper, 22 November 1969</ref>
Struck by camera during splashdown	Template:Nowrap	Template:Nowrap	Astronaut Alan Bean was struck above the right eyebrow by a 16mm movie camera when the spacecraft splashed down in the ocean. The camera broke free from its storage place. Bean suffered a concussion,<ref>Template:Cite book</ref> and a 1.25 cm cut above the eyebrow that required stitches.<ref>"Moon Men Healthy, Resting", The Fort Scott, KS – Tribune newspaper, 25 November 1969</ref>
Premature engine shutdown	Template:Nowrap	Template:Nowrap	During launch, the Saturn V second stage experienced a potentially serious malfunction when the center of its five engines shut down two minutes early. The remaining engines on the second and third stages were burned a total of 34 seconds longer to compensate, and parking orbit and translunar injection were successfully achieved. It was later determined that the shutdown was caused by pogo oscillation of the engine.<ref>"Third U.S. lunar mission leaves pad without hitch", Eugene, OR – Register-Guard newspaper, 11 April 1970</ref><ref>"Apollo 13 on way after engine fails", The Age newspaper, 13 April 1970</ref><ref>"Apollo 14 Tests Wait For Month", Youngstown Vindicator newspaper, 29 April 1970</ref>

One of three main parachutes failed	Template:Nowrap	Template:Nowrap	During descent, the three main parachutes opened successfully. However, when the remaining reaction control system fuel was jettisoned, one parachute was damaged by the discarded fuel causing it to collapse. Spacecraft and crew still splashed down safely, at a slightly higher than normal velocity, on the two remaining main parachutes. If a second parachute had failed, the spacecraft would probably have been crushed on impact with the ocean, according to a NASA official.<ref>"Rocket Fuel Gets Blame In Apollo Parachute Fluke", Lumberton, NC – The Robesonian newspaper, 13 August 1971</ref>
Separation failure	Template:Nowrap	Template:Nowrap	The mission nearly ended in disaster when the rocket suffered a second-stage separation failure during launch. This also interrupted the craft's attitude, causing the vehicle to accelerate towards the Earth and triggering an emergency reentry sequence. Due to the downward acceleration, the crew experienced an acceleration of 21.3 g rather than the nominal 15 g for an abort. Upon landing, the vehicle rolled down a hill and stopped just short of a high cliff. The crew survived, but Lazarev, the mission commander, suffered internal injuries due to the severe G-forces and was never able to fly again.
Chemical poisoning	Template:Nowrap	Apollo–Soyuz	During final descent and parachute deployment, the U.S. crew were exposed to 300 μL/L of toxic nitrogen tetroxide (Reaction Control System oxidizer) fumes venting from the spacecraft and reentering a cabin air intake, because a switch was left in the wrong position. 400 μL/L is fatal. Vance Brand lost consciousness for a short time. The crew members suffered from burning sensations of their eyes, faces, noses, throats and lungs. Thomas Stafford quickly broke out emergency oxygen masks and put one on Brand and gave one to Deke Slayton. The crew were exposed to the toxic fumes from 24,000 ft (7.3 km) down to landing. About an hour after landing the crew developed chemical-induced pneumonia and their lungs had edema. They experienced shortness of breath and were hospitalized in Hawaii. The crew spent five days in the hospital, followed by a week of observation in semi-isolation. By 30 July, their chest X-rays appeared to return to normal except for Slayton; he was diagnosed with a benign lesion, unrelated to the gas exposure, which was later removed.<ref>"Brand Takes Blame For Apollo Gas Leak", Florence, AL – Times Daily newspaper, 10 August 1975</ref>
Landing capsule sank in water	Template:Nowrap	Template:Nowrap	The capsule broke through the surface of a frozen lake and was dragged underwater by its parachute. The crew was saved after a very difficult rescue operation.<ref>"Cosmonauts Land in Lake, Blizzard", Milwaukee Journal newspaper, 18 October 1976</ref>
Engine malfunction	Template:Nowrap	Template:Nowrap	Engine failure forced the mission to be aborted. It was the first failure of a Soyuz engine during orbital operations. The crew, commander Nikolai Rukavishnikov and Bulgarian cosmonaut Georgi Ivanov, suffered a steep ballistic re-entry, but were safely recovered.
SRB ignition shock wave overpressure reached design limits of orbiter structure	Template:Nowrap	Template:Nowrap	During launch, the Solid Rocket Booster ignition shock wave overpressure was four times greater than expected (Template:Cvt measured vs Template:Cvt predicted). Some of the aft structures on Template:OV reached their design limits (2.0 psi) from the overpressure. The overpressure bent four struts that supported two RCS fuel tanks in the nose of Columbia and the orbiter's locked body flap was pushed up and down Template:Convert by the shock wave. John Young and Robert Crippen in the crew cabin received a 3-G jolt from the shock wave. An improved water spray shock wave damping system had to be installed on the launch pad prior to launch.<ref>"Shock Wave Doesn't Worry Shuttle Crew", Toledo Blade newspaper, 16 September 1981</ref><ref>"Shuttle shock wave problem still puzzles NASA", Richland, WA – Tri-City Herald newspaper, 11 September 1981</ref><ref>"Shuttle's Pressure Problem Studied", Toledo Blade newspaper, 27 June 1981</ref><ref>"Space Shuttle Columbia Nears Second Flight", Sarasota Herald Tribune newspaper, 25 October 1981</ref>
Fire in launch vehicle	Template:Nowrap	Soyuz T-10-1	A fuel spillage before the planned liftoff caused the vehicle to be engulfed in flames. The crew was narrowly saved by the activation of their launch escape system, with the rocket exploding two seconds later.
Leaked hydrazine fuel fire and explosion	Template:Nowrap	Template:Nowrap	In the last two minutes of the mission, during Template:OV's final approach to the Edwards AFB runway, hydrazine fuel leaked onto hot surfaces of two of the three onboard auxiliary power units (APU) in the aft compartment of the shuttle and caught fire. About 15 minutes after landing, hydrazine fuel trapped in the APU control valves exploded, destroying the valves in both APUs. The fire also damaged nearby wiring. The fire stopped when the supply of leaked fuel was exhausted. All of this was discovered the next day when technicians removed an access panel and discovered the area blackened and scorched. It is believed that hydrazine leaked in orbit and froze, stopping the leak. After returning, the leak restarted and ignited when combined with oxygen from the atmosphere. There were no injuries during the incident.<ref>"Fuel Devices on Space Shuttle Were on Fire During Landing", Schenectady Gazette newspaper, 12 December 1983</ref><ref>"Engineers Study Blaze Aboard Columbia", Ocala Star-Banner newspaper, 14 December 1983</ref>
Space Shuttle in-flight engine failure	Template:Nowrap	Template:Nowrap	Five minutes and 45 seconds into ascent, one of three main engines aboard Challenger shut down prematurely due to a spurious high temperature reading. At about the same time, a second main engine almost shut down from a similar problem, but this was observed and inhibited by a fast acting flight controller. The failed SSME resulted in an Abort To Orbit (ATO) trajectory, whereby the shuttle achieves a lower than planned orbital altitude. Had the second engine failed within about 20 seconds of the first, a Transoceanic Abort Landing (TAL) abort might have been necessary. No bailout option existed until after mission STS-51-L, the Challenger disaster. But even with that option, a bailout (a "contingency abort") would never be considered when an "intact abort" option exists, and after five minutes of normal flight it would always exist unless a serious flight control failure or some other major problem beyond engine shutdown occurred.Template:Sfnp<ref name="Shuttle Close Call 1985"> Template:Cite news </ref>
Sensor failure	Template:Nowrap	Template:Nowrap	At the end of the mission, Soviet cosmonaut Vladimir Lyakhov and Afghan cosmonaut Abdul Ahad Mohmand undocked from Mir in the spacecraft Soyuz TM-5. During descent they suffered a computer software problem combined with a sensor problem. The deorbit engine on the TM-5 spacecraft that was to propel them into atmospheric reentry, did not behave as expected. During an attempted burn, the computer shut off the engines prematurely, believing the spacecraft was out of alignment.Template:Sfnp Lyakhov determined that they were not, in fact, out of alignment, and asserted that the problem was caused by conflicting signals picked up by the alignment sensors caused by solar glare.Template:Sfnp With the problem apparently solved, two orbits later he restarted to deorbit engines. But the engines shut off again. The flight director decided that they would have to remain in orbit an extra day (a full revolution of the Earth), so they could determine what the problem was. During this time it was realised that during the second attempted engine burn, the computer had tried to execute the program that was used to dock with Mir several months earlier during EP-2.Template:Sfnp After reprogramming the computer, the next attempt was successful, and the crew safely landed on 7 September.Template:Sfnp
Thermal tile damage	Template:Nowrap	Template:Nowrap	Template:OV' Thermal Protection System tiles sustained unusually severe damage during this flight. Ablative insulating material from the right-hand solid rocket booster nose cap had hit the orbiter about 85 seconds into the flight, as seen in footage of the ascent. The crew made an inspection of the Shuttle's impacted starboard side using the Shuttle's Canadarm robot arm, but the limited resolution and range of the cameras made it impossible to determine the full extent of the tile damage. Following reentry, more than 700 tiles were found to be damaged including one that was missing entirely. STS-27 was the most heavily damaged Shuttle to return to Earth safely.
Space suit puncture	Template:Nowrap	Template:Nowrap	During an extravehicular activity, a small stainless steel bar (palm bar) in a glove of EV2 astronaut Jay Apt's extravehicular mobility unit punctured the suit. The suit's pressure bladder and thin comfort glove conformed to the puncture and sealed it, preventing any detectable depressurization. Apt was unaware of the failure during the EVA, learning of it only when the suit manager phoned him the evening after he returned to Houston. During post-flight debriefings, Apt said after the second EVA, when he removed the gloves, his right hand had an abrasion behind the knuckle of the index finger. A postflight inspection of the right hand glove found the palm bar of the glove penetrating a restraint and glove bladder into the index finger side of the glove. NASA found air leakage with the bar in place was 3.8 SCCM, well within the specification of 8.0 SCCM. They said if the bar had come out of the hole, the leak still would not have been great enough to activate the secondary oxygen pack. The suit would, however, have shown a high oxygen rate indication.<ref>"STS-37 Space Shuttle Mission Report May 1991 – NASA-CR-193062", Extravehicular Activity Evaluation, Page 16, accessed online 4 Jan 2011</ref>

Collision in space	Template:Nowrap	Template:Nowrap	At Mir, during the 2nd docking attempt the Progress M-24 cargo freighter, the Progress freighter collided with the space station causing minor damage to the space station that was crewed at that time.
Eye injury from Mir exercise equipment	Template:Nowrap	Template:Nowrap	While exercising on the EO-18/NASA 1/Soyuz TM-21 mission, astronaut Norman E. Thagard suffered an eye injury. He was using an exercise device, doing deep knee bends, with elastic straps. One of the straps slipped off of his foot, flew up, and hit him in the eye. Later, even a small amount of light caused pain in his eye. He said using the eye was, "like looking at the world through gauze." An ophthalmologist at Mission Control-Moscow prescribed steroid drops and the eye healed.<ref>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
Fire on board	Template:Nowrap	Template:Nowrap	There was a fire on board the Mir space station when a lithium perchlorate canister used to generate oxygen leaked. The fire was extinguished after about 90 seconds, but smoke did not clear for several minutes.
Fuel cell failure	Template:Nowrap	Template:Nowrap	Fuel cell #2 aboard Template:OV unexpectedly failed on Day 4 in orbit, forcing an early end to the flight. The mission touched down safely, and the crew was reflown with the same mission plan on STS-94.
Collision in space	Template:Nowrap	Template:Nowrap	At Mir, during a re-docking test with the Progress M-34 cargo freighter, the Progress freighter collided with the Spektr module and solar arrays of the Mir space station. This damaged the solar arrays and the collision punctured a hole in the Spektr module and the space station began depressurizing. The onboard crew of two Russians and one visiting NASA astronaut were able to close off the Spektr module from the rest of Mir after quickly cutting cables and hoses blocking the hatch closure.
Main engine electrical short and hydrogen leak	Template:Nowrap	Template:Nowrap	Five seconds after liftoff, an electrical short knocked out controllers for two shuttle main engines. The engines automatically switched to their backup controllers. Had a further short shut down two engines, Columbia would have ditched in the ocean, although the crew could have possibly bailed out. Concurrently a pin came loose inside one engine and ruptured a cooling line, allowing a hydrogen fuel leak. This caused premature fuel exhaustion, but the vehicle safely achieved a slightly lower orbit. Had the failure propagated further, a risky transatlantic or RTLS abort would have been required.
Toxic ammonia leak during EVA	Template:Nowrap	ISS/STS-98	During EVA 1 on the mission, NASA astronauts Robert L. Curbeam and Thomas D. Jones were connecting cooling lines on the International Space Station while working to install the Destiny laboratory module. A defective quick-disconnect valve allowed 5% of the ammonia cooling supply to escape into space. The escaping ammonia froze on the spacesuit of astronaut Curbeam as he struggled to close the valve. His helmet and suit were coated in ammonia crystals an inch thick. Mission Control instructed Curbeam to remain outside for an entire orbit to allow the Sun to evaporate the frozen ammonia from his spacesuit. When they returned to the airlock, the astronauts pressurized, vented and then repressurized the air lock to purge any remaining toxic ammonia. After they removed their spacesuits, the crew wore oxygen masks for another 20 minutes to allow life-support systems in the airlock to further filter the air. No injuries resulted from the incident.<ref>Template:Cite news</ref>
Ballistic reentry, injured shoulder	Template:Nowrap	Soyuz TMA-1	The capsule had a malfunction during its return to Earth from the ISS Expedition 6 mission and performed a ballistic reentry. The crew was subjected to about 8 to 9 Gs during reentry. The capsule landed Template:Convert from the intended landing target. In addition, after landing the capsule was dragged about Template:Convert by its parachute and ended up on its side in a hard landing.

Unplanned rolls during ascent	Template:Nowrap	SpaceShipOne-16P	On suborbital flight 16P, the first of two flights that won the X-Prize for exceeding Template:Cvt in altitude, astronaut Mike Melvill experienced 29 unplanned rolls during and after powered ascent. The rolls began at 50 seconds into the engine burn. The burn was stopped 11 seconds early after burning a total of 76 seconds. After engine cutoff, the craft continued rolling while coasting to apogee. The roll was finally brought under control after apogee using the craft's reaction jets. SpaceShipOne landed safely and Mike Melvill was uninjured.<ref>"Private rocket plane goes rolling into space", The Southeast Missourian newspaper, 30 September 2004</ref><ref>"SpaceShipOne Rolling Rumors: Rutan Sets the Record Straight", Space.com website – posted: 2 October 2004, accessed online 4 January 2011</ref>
Separation failure	Template:Nowrap	Soyuz TMA-11	Reentry mishap similar to that suffered by Soyuz 5 in 1969. The service module failed to completely separate from the reentry vehicle and caused it to face the wrong way during the early portion of aerobraking. As with Soyuz 5, the service module eventually separated and the reentry vehicle completed a rough but survivable landing.

Aborted spacewalk after water leak in suit	Template:Nowrap	ISS Expedition 36	During EVA-23, European Space Agency astronaut Luca Parmitano reported that water was steadily leaking into his helmet. Flight controllers elected to abort the EVA immediately, and Parmitano made his way back to the Quest airlock, followed by fellow astronaut Chris Cassidy. The airlock began repressurizing after a 1-hour and 32 minute spacewalk, and by this time Parmitano was having difficulty seeing, hearing, and speaking due to the amount of water in his suit. After repressurization, Expedition 36 commander Pavel Vinogradov and crewmembers Fyodor Yurchikhin and Karen Nyberg quickly removed Parmitano's helmet and soaked up the water with towels. Despite the incident, Parmitano was reported to be in good spirits and suffered no injury.<ref>"EVA-23 terminated due to EVA-23 terminated due to Parmitano EMU issue", NASASpaceFlight, 16 July 2013</ref><ref>"Spacewalk aborted by spacesuit water leak", SpaceflightNow, 16 July 2013</ref><ref>"Tuesday Spacewalk Ended Early", NASA, 16 July 2013</ref> By December 2013, NASA had determined the leak to have been caused by a design flaw in the Portable Life Support System liquid coolant. The designers failed to take into account the physics of water in zero-g, which unintentionally allowed coolant water to mix with the air supply.<ref>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
Hole detected in spacecraft	30 August 2018	Soyuz MS-09	Ground controllers detected a dip in cabin pressure, which astronauts traced to a 2-millimeter hole in Soyuz MS-09, which was quickly patched up by Soyuz commander Sergey Prokopyev with epoxy.<ref>Template:Cite news</ref>
Launch booster failure, ballistic re-entry	11 October 2018	Soyuz MS-10	The crew reported feeling weightless; mission control declared a rocket had failed. An emergency was declared and the spacecraft carrying the crew was separated from the rocket. It returned to Earth in a ballistic descent (sharper than normal angle), and the crew experienced 6.7 G during the landing.<ref name="cnn1">Astronauts survive Soyuz rocket emergency landing CNN, 11 October 2018.</ref> The crew did not need immediate medical care when recovered. Investigation determined the ball joint supporting one of the side boosters had been deformed during assembly; the damaged joint prevented proper separation despite proper activation of the separation motors; the booster re-contacted the core stage, inflicting further damage.
Air leak in space station	August 2020	Expedition 63	NASA reported an air leak from the International Space Station during Expedition 63. The source of the leak was traced to the Zvezda module, but its exact location was unknown.<ref>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
Uncontrolled spin of Space Station	29 July 2021	Expedition 65	NASA reported an uncontrolled spin event after docking of the Russian Nauka module that replaced Pirs. It appears that the module's onboard computers incorrectly determined that it was still in open space rather than docked and fired its thrusters. Controllers had to fire the thrusters on Progress to counteract the (270 degree) spin and bring the station back into its correct orientation complicated by the module being out of range of Russian ground control stations, eventually however its propellant depleted and the situation was resolved.<ref>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>

As an interim measure in case of an emergency evacuation is required, the seat of NASA Astronaut Frank Rubio will be moved to Crew Dragon Endurance with SpaceX Crew-5 while Prokopyev and Petelin would return to earth on MS-22. Once MS-23 arrives, the seats of Prokopyev, Petelin and Rubio would be moved to MS-23. As well, Sergei Krikalev of Roscosmos stated that the crew of MS-22 would have their mission extended by "at least, several more months" to allow the preparation of Soyuz MS-24.<ref>{{#invoke:citation/CS1|citation	CitationClass=web }}</ref>
