On theInternational Space Station (ISS),extravehicular activities are major events in the building and maintaining of the orbital laboratory,^[1] and are performed to install new components, re-wire systems, modules, and equipment, and to monitor, install, and retrieve scientific experiments.^[2]^[3]

An artist's rendering from 2023 of the fully assembled International Space Station

Due to the complexity of building a station inspace, space agencies train astronauts extensively, preparing them to encounter surprises during spacewalks, teaching them how to assemble special tools and equipment, and carefully coordinating every activity during spacewalks.^[1] From 1998 to 2005,thirty-seven Space Shuttle missions were scheduled to assemble, outfit and beginexperiments and research aboard the station.^[1]

The initial spacewalk to begin theassembly of the International Space Station was held on 7 December 1998,^[4] following the launch of the first section of the station,Zarya, fromBaikonur Cosmodrome,Kazakhstan, on 20 November 1998.^[5] The spacewalk attached the U.S.-builtUnity node toZarya.^[4] The longest spacewalk was performed on 11 March 2001, whenSTS-102 crew membersSusan J. Helms andJames S. Voss conducted a full spacewalk, and then returned to the airlock, but remained in their suits ready to exit the airlock again in case the robotics operations ran into problems. The total time for that spacewalk was eight hours and fifty-six minutes.^[6]

As of 2 December 2021, there have been 245 spacewalks devoted to assembly and maintenance of the International Space Station totaling 1548 hours and 26 minutes. Thirty-seven of those spacewalks were performed from a shuttle, ninety-three from theQuest Joint Airlock, thirty-two from thePirs docking compartment, and two from the transfer compartment at the forward end of theZvezda service module.^[7]^[8]

142.	STS-131 EVA 2	The old ammonia tank was removed from the S1 truss and was replaced with the new tank. The electrical connections to the tank were made, but the fluid lines were deferred to the mission's third EVA due to time constraints since the installation was prolonged by a problem with the bolts that hold the tank to the truss. The old tank was relocated to a temporary stowage location on the station and a foot restraint was relocated in preparation for a future shuttle mission's spacewalk.
143.	STS-131 EVA 3	Richard Mastracchio Clayton Anderson	13 April 2010 06:14	13 April 2010 12:36	6 hours, 24 minutes
143.	STS-131 EVA 3	The fluid lines were connected to the new ammonia tank and the old tank was moved to the shuttle's payload bay for return to Earth.

148.	Expedition 24 EVA 2	Attempted to replace a failed ammonia pump module located on the S1 truss. Due to an ammonia leak in the final line that needed to be disconnected from the failed pump module, the planned tasks were only partially completed, and the spacewalkers needed extra time to perform a "bake out" to ensure no ammonia entered the station following the EVA. This was the longest International Space Station-based spacewalk, and the sixth longest spacewalk in history.^[156]^[157]

154.	STS-133 EVA 1	Drew and Bowen installed a power extension cable between the Unity and Tranquility nodes to provide a contingency power source should it be required. The spacewalkers then moved the failed ammonia pump module that was replaced in August from its temporary location to the External Stowage Platform 2 adjacent to the Quest airlock. Drew and Bowen then installed a wedge under a camera on the S3 truss to provide clearance from the newly installed ELC-4. They next replaced a guide for the rail cart system used for moving the station robotic arm along the truss. The guides had been removed when astronauts were performing work on the station's starboard Solar Alpha Rotary Joint (SARJ), which rotates the solar arrays to track the sun. The final task was to "fill" a special bottle with the vacuum of space for a Japanese education payload. The bottle will be part of a public museum exhibit.
155.	STS-133 EVA 2	Stephen Bowen Alvin Drew	2 March 2011 15:42	2 March 2011 21:56	6 hours, 14 minutes

They installed jumpers between segments on the left-side truss, or backbone of the station, forammonia refills; ventednitrogen from an ammonia servicer; they began to install an external wireless communication antenna on theDestiny laboratory that will provide wireless communication to the Express Logistics Carriers mounted on the station's truss, but was cut short due to a badCO₂ sensor in Chamitoff's suit.
157.	STS-134 EVA 2	Andrew Feustel Michael Fincke	22 May 2011 6:05	22 May 2011 14:12	8 hours, 07 minutes
157.	STS-134 EVA 2	Feustel and Fincke refilled the Port 6 (P5) radiators with ammonia. They completed venting the early ammonia system, lubricated the port solar alpha rotary joint and parts ofDextre, a two-armed space station robot capable of handling delicate assembly tasks currently performed by spacewalkers. Fincke also installed grapple bars on the port radiators.
158.	STS-134 EVA 3	Andrew Feustel Michael Fincke	25 May 2011 05:43	25 May 2011 12:37	6 hours, 54 minutes
158.	STS-134 EVA 3	Feustel and Fincke installed a grapple fixture (a handle for the station'sCanadarm2 to grab on to) on theZarya module, to support robotic operations based from the Russian segment. They also installed additional cables to provide backup power to the Russian portion of the space station. The pair finished installing the wireless video system that was left unfinished during EVA 1.
159.	STS-134 EVA 4	Michael Fincke Gregory Chamitoff	27 May 2011 04:15	27 May 2011 11:39	7 hours, 24 minutes
159.	STS-134 EVA 4	Fincke and Chamitoff stowed the shuttle's 50-footOrbiter Boom Sensor System (OBSS) on the right-side truss on a permanent stowage fixture. The pair then retrieved a grapple from the station's left-side truss and used it as a replacement for the grapple currently on the boom. They then released restraints from one of the arms spare arms for Dextre and replaced thermal insulation on one of the spare gas tanks for theQuest airlock. The arrival of the PMM module marked the completion of the US Orbital Segment.^[168] This was the final EVA from the Space Shuttle before its retirement.

160.	Expedition 28 EVA 1	Ronald J. Garan Jr. Michael E. Fossum	12 July 2011 13:22	12 July 2011 19:53	6 hours, 31 minutes
160.	Expedition 28 EVA 1	This spacewalk was kind of special in that it was the last spacewalk performed while a space shuttle was docked to the station. However, other than the previous spacewalks during docked operations, this one was performed by the station crew and not by the space shuttle crew. The need for this spacewalk arose since a failed pump module on the station should be returned for inspection to the ground on the space shuttle. This having been the main objective done during this EVA the spacewalkers also installed a Robotic Refueling Mission experiment and fully deployed theMISSE 8 experiment (which was only half deployed during a previous spacewalk).^[169]^[170]

#	Mission	Spacewalkers	Start (UTC)	End (UTC)	Duration
214.	Expedition 59 EVA 1	Anne McClain Nick Hague	22 March 2019 13:01	22 March 2019 19:40	6 hours, 39 minutes
214.	Expedition 59 EVA 1	McClain and Hague installed adapter plates whileDextre swapped the batteries between spacewalks. Get ahead task included removing debris from theUnity Module in preparation for the arrival ofCygnus NG-11 in April, stowing tools for the repair of the flex hose rotary coupler, and securing tiebacks on the solar array blanket boxes. This spacewalk was originally going to be carried out by European astronautAlexander Gerst and Hague as part ofExpedition 57, although it was delayed due to theSoyuz MS-10 launch abort.^[243] Anne McClain became the 13th woman to perform a spacewalk.
215.	Expedition 59 EVA 2	Nick Hague Christina Koch	29 March 2019 11:42	29 March 2019 18:27	6 hours, 45 minutes
215.	Expedition 59 EVA 2	Hague and Koch finished the work of the first spacewalk and installed the final three adapter plates on the other side of the P4 Truss. The crew also transferred some tools and installed a grapple bar on the flex hose rotary coupler. Between spacewalks, Dextre changed the batteries and the exposed pallet was loaded ontoHTV-8 and jettisoned into space to burn up. One of the batteries malfunctioned and was removed by Dextre and discarded. Dextre also installed a Battery Discharge Unit and bought the failed unit which was damaged by the short inside where it was returned to earth onSpaceX CRS-17. Until the battery is repaired P4 will use the old batteries left on the station as spares. Get ahead task included installing gap spanners and breaking torque on the P6 batteries in preparation for their replacement byExpedition 61 crew members that fall. Hague also inspected sockets on P6 so the foot restraints could be attached. This spacewalk was supposed to be done by Anne McClain and Christina Koch as an all female spacewalk but because of problems with Christina's suit and the spare suit not ready or properly sized Anne McClain sat this spacewalk out and went out with David on the next spacewalk.^[244] This spacewalk became the first for Koch who became the 14th woman to walk in space.^[245]
216.	Expedition 59 EVA 3	Anne McClain David Saint-Jacques	8 April 2019 11:31	8 April 2019 18:00	6 hours, 29 minutes
216.	Expedition 59 EVA 3	McClain and Saint Jacques routed cables to be used as a redundant power supply forCanadarm2. The crew installed studs on theColumbus Module in preparation for the installation of theBartolomeo exposed facility. The crew removed an adapter plate and reinstalled an old set of batteries as spares to replace a failed battery that malfunctioned on the last spacewalk. Saint Jacques became the fourth Canadian to do a spacewalk, the first Canadian ISS crew member to walk in space, and the first Canadian spacewalker sinceDafydd Williams.^[246]
217.	Expedition 59 EVA 4 *	Oleg Kononenko Aleksey Ovichinin	29 May 2019 15:42	29 May 2019 21:43	6 hours, 01 minute
217.	Expedition 59 EVA 4 *	Kononenko and Ovichinin removed experiments from thePirs docking compartment and cleaned the windows. They also installed a ladder to connectZarya toPoisk and re-positioned the Plume Measuring Unit. The crew then moved to theZvezda Service Module and removed and jettisoned the Plasma Monitoring Units. Before they closed the hatch they sent a video of themselves and sang happy birthday in Russian toAlexei Leonov who was the first spacewalker and was celebrating his 85th birthday.^[247]

218.	Expedition 60 EVA 1	Nick Hague Andrew R. Morgan	21 August 2019 12:27	21 August 2019 18:59	6 hours, 32 minutes
218.	Expedition 60 EVA 1	Hague and Morgan installed the finalInternational Docking Adapter on theHarmony Module. Task for this spacewalk were identical to Spacewalk 194 and required work by both spacewalkers andDextre to get the docking port installed. The crew also routed cables and installedWi-Fi routers for upcoming experiments.^[248]

219.	Expedition 61 EVA 1	Christina Koch Andrew R. Morgan	6 October 2019 11:39	6 October 2019 18:40	7 hours, 01 minute

220.	Expedition 61 EVA 2	This spacewalk was the second of Expedition 61 and the second of a series of 5 to replace and improve ISS batteries on the P6 truss. Before they went out the hatchMission Control Moscow relayed to the crewAlexei Leonov had died and this spacewalk is dedicated to him. As the crew came in and took off their suits each gave a choice of words before station commander Luca Parmitano said "Farewell Alexei, and ad astra."^[250]^[251]
221.	Expedition 61 EVA 3	Christina Koch Jessica Meir	18 October 2019 11:38	18 October 2019 18:55	7 hours, 17 minutes
221.	Expedition 61 EVA 3	This spacewalk was the third of Expedition 61 and the third of a series of 5 to replace and improve ISS batteries on the P6 truss. Some of the battery swaps have been moved to EVA 225 and a later date because of a power failure in a Battery Charge Discharge Unit in slots 5 and 6 on the P6 Truss taking the 4B battery channel offline. Koch and Meir went outside and replaced the failed unit and brought it inside. The battery swap was moved to EVA 225 to save time and Meir and Koch wrapped up the spacewalk by installing a stanchion on theColumbus Module and tightening the bolts on the S0 Truss which had come loose. This spacewalk was the first all female spacewalk on the station. During the spacewalk,President Trump called the station and congratulated Koch and Meir on this milestone.^[252]
222.	Expedition 61 EVA 4	Luca Parmitano Andrew R. Morgan	15 November 2019 11:39	15 November 2019 18:18	6 hours, 39 minutes
222.	Expedition 61 EVA 4	First of a series of four spacewalks to repair theAlpha Magnetic Spectrometer which suffered a power failure last year in one of its four cooling pumps limiting the operation of the experiment. Parmitano and Morgan went outside and removed a cover plate from AMS and jettisoned it into space to make way for a cryo pump that they will assemble between spacewalks. Some of the bolts put up a fight but Parmitano got them all out. The highlight of the spacewalk is when Andrew R. Morgan threw the cover plate overboard and it drifted off aft of the station into the vacuum of space. The plate will stay in orbit for a few days until the end of December when it enters the atmosphere and burns up. The crew also removed several carbon fiber strips around fluid lines and installed handrails and grapple bars as get-ahead task. This spacewalk marks Parmitano's return to spacewalking after the Water in the Helmet Incident during EVA 171.^[253]
223.	Expedition 61 EVA 5	Luca Parmitano Andrew R. Morgan	22 November 2019 12:02	22 November 2019 16:35	6 hours, 33 minutes
223.	Expedition 61 EVA 5	The second in a series of four spacewalks to repair the AMS. Parmitano and Morgan cut fluid lines and installed a vent on the AMS Experiment to prep the old cooling pump for removal on the third spacewalk. Parmitano and Morgan also routed cables and installed a new power supply to power the pumps when they are installed on the third spacewalk.^[254]
224.	Expedition 61 EVA 6	Luca Parmitano Andrew R. Morgan	2 December 2019 11:31	2 December 2019 17:33	6 hours, 02 minutes
224.	Expedition 61 EVA 6	The third in a series of four spacewalks to repair the AMS. Parmitano and Morgan went out on the third spacewalk and installed the cryo pump and routed fluid and electrical lines to power the pump. Flight controllers inHouston,Huntsville, and atCERN activated the experiment and radioed to the crew that AMS passed with flying colors. The crew finished the spacewalk by doing a get-ahead task by covering AMS with thermal blanket.^[255]

225.	Expedition 61 EVA 7	Christina Koch Jessica Meir	15 January 2020 11:35	15 January 2020 19:04	7 hours, 29 minutes
225.	Expedition 61 EVA 7	The fourth in a series of five spacewalks to replace the batteries on the P6 Truss. Spacewalk suffered a 15-minute delay when Koch lost her helmet lights and camera. Meir managed to attach a hook onto the camera to prevent it from floating away and stowed it in Koch's tool bag. The spacewalkers managed to replace two batteries plus a third as a getahead task and had to stay in signal range of the WETA antennas so Meir could check on Koch at night who did not have any helmet lights. The spacewalkers replaced the camera between spacewalks and headed back out to replace the final three batteries on the next spacewalk.^[256]
226.	Expedition 61 EVA 8	Christina Koch Jessica Meir	20 January 2020 11:35	20 January 2020 18:33	6 hours, 58 minutes
226.	Expedition 61 EVA 8	The fifth and final in a series of five spacewalks to replace the batteries on the P6 Truss. Koch and Meir managed to get all the batteries replaced and stored two old ones on the exposed pallet to return to Earth onKounotori 9 where they will be incinerated on reentry. Koch and Meir finished the day by sending down a message to commemorateMartin Luther King Jr. Day. Today's spacewalk moves Koch up to third place and Meir up to fourth place on the all time female spacewalker list.^[257]
227.	Expedition 61 EVA 9	Andrew R. Morgan Luca Parmitano	25 January 2020 12:04	25 January 2020 18:20	6 hours, 16 minutes
227.	Expedition 61 EVA 9	The fourth and final in a series of four spacewalks to repair the AMS. Spacewalk suffered a 10-minute delay when a strap got stuck in the hatch preventing depressurization of the airlock. The two spacewalkers completed all the task and at 17:30 hours Luca Parmitano opened a valve to start the flow of CO2 gas to AMS and contactedCERN to turn the experiment on. AMS passed all test and worked flawlessly. A leak was found in a cooling line but Parmitano patched it and the spacewalk resumed without incident. As a getahead task Parmitano and Morgan cleaned and replaced glare filters on theNASA TV cameras used to film the spacewalk.^[258]

228.	Expedition 63 EVA 1	Chris Cassidy Robert Behnken	26 June 2020 11:32	26 June 2020 17:39	6 hours, 07 minutes
228.	Expedition 63 EVA 1	First in a series of four spacewalks to replace oldNickel-hydrogen batteries on the ISSS6 Truss segment with newLithium-ion batteries. Behnken is not a member of the Expedition 63 crew but instead is flying as Joint Operations Commander onSpaceX's Crew Dragon Demo-2 mission, which was extended so that the mission's two crew members could support ISS operations for an extended period of time. At the conclusion of the spacewalk the two batteries were turned on and the ground reported that they were working and that there were no signs of a short.^[259]
229.	Expedition 63 EVA 2	Chris Cassidy Robert Behnken	1 July 2020 11:13	1 July 2020 16:14	6 hours, 01 minute
229.	Expedition 63 EVA 2	Second in a series of four spacewalks to replace oldnickel-hydrogen batteries on the ISSS6 Truss segment with newlithium-ion batteries. Route cables for a new wireless communications system.^[260]
230.	Expedition 63 EVA 3	Chris Cassidy Robert Behnken	16 July 2020 11:10	16 July 2020 17:10	6 hours, 00 minutes
230.	Expedition 63 EVA 3	Third in a series of four spacewalks to replace oldnickel-hydrogen batteries on theS6 Truss segment with newlithium-ion batteries. That work was completed with this EVA. Installed a high-definition camera boom on the inboard power truss and begin preparations of Tranquility (Node 3) port for installation of theBishop Airlock Module.^[261]
231.	Expedition 63 EVA 4	Chris Cassidy Robert Behnken	21 July 2020 11:12	21 July 2020 16:41	5 hours, 29 minutes
231.	Expedition 63 EVA 4	Fourth in a series of four spacewalks for Expedition 63. Install robotics tool box on a rail-mounted carrier used to move the station's robot arm from one worksite to another, remove two of six ground-handling "H" fixtures at the base of the solar wings for future upgrades, routing and connecting Ethernet cables for external experiment data transmission, and conclude preparations of Tranquility (Node 3) port for installation of theNanoracks Bishop Airlock (CRS-21).^[262]

232.	Expedition 64 EVA 1 ^	Sergey Ryzhikov Sergey Kud-Sverchkov	18 November 2020 15:12	18 November 2020 22:00	6 hours, 48 minutes
232.	Expedition 64 EVA 1 ^	First in a series of spacewalks to decommission thePirs Airlock which is scheduled to be replaced byNauka in the summer of 2021. Task involved testingPoisk so the crew can egress, performing leak checks on the hatch, moving an antenna over to Poisk, cleaningZvezda's windows, repositioning the Plume Measuring Unit on thePoisk module, retrieving and replacing an Impact panel onZvezda, and replacing a fluid flow regulator onZarya.^[263]^[264] Spacewalk faced a delay when the bolt on the catch of the pressurized container did not release and the cosmonauts had the wrong socket wrench for the task. The fluid flow regulator will be replaced at a later date with a new unit once the pressurized container is fixed. Because of time the window cleaning was also moved to another spacewalk because the task is non critical.^[265]

#	Mission	Spacewalkers	Start (UTC)	End (UTC)	Duration
233.	Expedition 64 EVA 2	Michael Hopkins Victor Glover	27 January 2021 11:28	27 January 2021 18:24	6 hours, 56 minutes
233.	Expedition 64 EVA 2	Spacewalk to activate and install theAirbusBartolomeo exposed experiment platform and the ColumbusKa band Terminal (COL-Ka) ontoColumbus. Remove H fixtures from the P-6 Truss in preparation for installation of upgrades to the solar arrays. Due to issues with the installation ofBartolomeo, only four out of the six cables could be installed. The platform is "partially operational and in a safe configuration" according toNASA; the final two cables will be installed on a future spacewalk. ESA astronautAndreas Mogensen was Ground IV.^[266]^[267]^[268]^[269]
234.	Expedition 64 EVA 3	Michael Hopkins Victor Glover	1 February 2021 12:56	1 February 2021 18:16	5 hours, 20 minutes
234.	Expedition 64 EVA 3	Installed a new lithium-ion battery on the P-4 truss, where an earlier lithium replacement blew a fuse in April 2019.

235.	Expedition 64 EVA 4	Kathleen Rubins Victor Glover	28 February 2021 11:12	28 February 2021 18:16	7 hours, 04 minutes
235.	Expedition 64 EVA 4	Installed 2B modification kit to prepare Station for new solar array installation. If time allows they will also assemble the 4B modification kit and stow the brackets for installation of the new solar arrays. Due to issues with the 2B array one of the bolts failed to engage so Rubins backed it out and tightened it with a torque wrench before engaging it with her drill placing the upgrade kit in a safe configuration. The spacewalkers started work on the 4B array before time ran out and only got the triangles and one of the struts installed. The final struts will be installed on the next spacewalk and the next group will bring tools to tighten the bolts on the 2B array.NASA astronautFrank Rubio was Ground IV.^[271]^[272]^[273]
236.	Expedition 64 EVA 5	Kathleen Rubins Soichi Noguchi	5 March 2021 11:37	5 March 2021 18:33	6 hours, 56 minutes
236.	Expedition 64 EVA 5	Finished installation of the 4B modification kit.^[273] Some of the bolts did not engage but Rubins left them in a safe configuration. Because of time some of the task on this spacewalk were moved to the next spacewalk. Rubins and Noguchi finished the spacewalk by relocating their foot restraints for the next spacewalk.^[274]
237.	Expedition 64 EVA 6	Michael Hopkins Victor Glover	13 March 2021 13:14	13 March 2021 20:01	6 hours, 47 minutes
237.	Expedition 64 EVA 6	Vented ammonia jumpers on P6, Installed WETA Antennas and Ethernet Routers on theUnity Module and Camera 9 on the truss, installed stiffiners on theQuest Airlock and cleaned theBartolomeo jumper cables and activated the module.^[275] Spacewalk faced a delay in setup because of issues with Hopkin's snoopy cap. The cap will be returned to Houston and replaced. Because of time the task to install cable clamps onBartolomeo and to route an Ethernet router on the S6 Truss were moved to a later spacewalk.^[276]

238.	Expedition 65 EVA 1 ^	Oleg Novitsky Pyotr Dubrov	2 June 2021 05:53	2 June 2021 13:12	7 hours, 19 minutes
238.	Expedition 65 EVA 1 ^	Second in a series of spacewalks to decommission thePirs Airlock which is scheduled to be replaced byNauka in the summer of 2021. Task involve installing a flow control valve onZarya, removing docking antennas and their cables on Pirs, removing EVA gap spanners from Pirs, transferring experiments over toPoisk, installing Test containers on the hatches, and relocating aStrela crane over to Poisk. Getahead task involve cleaning the windows on the Russian segment, and doing an inspection ofZvezda and plugging any leaks they find. Because of time the cosmonauts did not get to the getahead task because of a late start and issues with the hatch on the pressurized container. These task will be done on the next spacewalk whenRoscosmos makes sure they have safe conditions to perform the task.^[277]^[278]^[279]
239.	Expedition 65 EVA 2	Thomas Pesquet Shane Kimbrough	16 June 2021 12:11	16 June 2021 19:26	7 hours, 15 minutes
239.	Expedition 65 EVA 2	First in a series of spacewalks to install theiROSA solar arrays on the P6 Truss. While working on releasing the arrays from their launch carrier, Kimbrough's spacesuit experienced issues with its Display and Control Module (DCM), so he was sent back to the airlock to connect to station umbilicals to restart it. The restart was successful, although it delayed the EVA. Additionally, an issue was discovered with his suit's sublimator, which threatened to end the EVA prematurely; this was determined to be a false reading, allowing work to resume. Following this, the astronauts successfully released the solar arrays and installed them on the P6 mounting bracket. A subsequent attempt to unfold the two rolled arrays, which were folded side by side during launch, failed due to interference (blockage) from a structure near the mounting area. As the EVA was then past the six-hour mark, ground controllers instructed the astronauts to finish securing the array structure to the station, photograph the work site, and return to the airlock. The next steps of unfolding the array pair, making electrical connections, and unfurling the rolled arrays were postponed to a future EVA pending ground analysis of the interference issue. CSA astronaut Jenni Sidey was Ground IV.^[280]^[281]
240.	Expedition 65 EVA 3	Thomas Pesquet Shane Kimbrough	20 June 2021 11:42	20 June 2021 18:10	6 hours, 28 minutes
240.	Expedition 65 EVA 3	Second in a series of spacewalks that will install the iROSA solar arrays on the P6 Truss. The spacewalkers managed to connect iROSA with a little elbow grease and at 16:40 hours deployed it and it is receiving power. CSA astronaut Jenni Sidey was Ground IV.^[282]^[283]
241.	Expedition 65 EVA 4	Thomas Pesquet Shane Kimbrough	25 June 2021 11:52	25 June 2021 18:37	6 hours, 45 minutes
241.	Expedition 65 EVA 4	Third in a series of spacewalks that will install the iROSA solar arrays on the P6 Truss. The spacewalkers completed all the task and at 17:45 hours the arrays were deployed and are generating power. Because of time they did not get to the get ahead task and they will have to be moved to another spacewalk. CSA astronaut Jenni Sidey was Ground IV.^[284]^[285]
242.	Expedition 65 EVA 5 ^	Oleg Novitsky Pyotr Dubrov	3 September 2021 14:41	3 September 2021 22:35	7 hours, 54 minutes
242.	Expedition 65 EVA 5 ^	First in a series of spacewalks to outfitNauka. The cosmonauts routed power and Ethernet cables interconnectingNauka with the US segment viaZarya andPMA-1, and installed EVA handrails alongNauka's exterior. The complex series of tasks planned for this EVA was budgeted at a nominal 7 hours, but was delayed substantially by cumulative minor complications, ultimately stretching to nearly 8 hours with several tasks postponed. The power cables were successfully mated and a good power path was confirmed by ground controllers; the Ethernet cables were routed but not all connections were mated due to lack of time. Mating of the final Ethernet cables and jettisoning of the cable reel were deferred to a future spacewalk. One of the three planned handrail installations was partially completed, but had trouble with one of its screws as the EVA was then past the 7-hour mark, ground controllers instructed Dubrov to attach it temporarily with wire ties for completion on the next EVA. Additional tasks deferred to future EVAs include the installation of threeBiorisk microorganism exposure experiment modules on the exterior of the station, and a photo survey of theZarya module's exterior.^[286]^[287]
243.	Expedition 65 EVA 6 ^	Oleg Novitsky Pyotr Dubrov	9 September 2021 14:51	9 September 2021 22:16	7 hours, 25 minutes
243.	Expedition 65 EVA 6 ^	Second in a series of spacewalks to outfitNauka.^[288]^[289] The cosmonauts continued where they left off from EVA 5, finishing Ethernet cable connections and installing four EVA handrails onNauka (including the troublesome one left incomplete from EVA 5). They subsequently connected cable bundles betweenNauka andZvezda, providing Ethernet links between those modules as well as links forNauka's TV cameras and docking navigation antennas (Kurs andTORU). They then mounted threeBiorisk microorganism exposure experiment modules on the exterior of thePoisk airlock module. Additionally, the cosmonauts took survey photos of the exterior of the Russian segment of the station, including the Kurs docking antennas of theProgress MS-17 cargo vehicle (confirming that they were undamaged) and external sensors onNauka; they also realigned a thruster plume measurement unit onPoisk. Finally, the cosmonauts tied together and jettisoned a junk cable reel cover along with some leftover insulation from theBiorisk experiments.^[289]
244.	Expedition 65 EVA 7	Akihiko Hoshide Thomas Pesquet	12 September 2021 12:15	12 September 2021 19:09	6 hours, 54 minutes

246.	Expedition 66 EVA 2 ^	First spacewalk of 2022 to connect thePrichal Node Module to the ISS. Task included relocating theStrela crane over toNauka so it can be used as a translation path for this spacewalk and the next one 249 or Russian Spacewalk 52, connecting telemetry and power cables, installing handrails, relocating TV cameras and docking antennas, installing docking targets, and jettisoning unneeded hardware and trash.^[293]^[294]^[295]
247.	Expedition 66 EVA 3	Kayla Barron Raja Chari	15 March 2022 12:12	15 March 2022 19:06	6 hours, 54 minutes
247.	Expedition 66 EVA 3	First spacewalk to install theIROSA mounting brackets on the S4 Truss. Task included installing the struts, mounting brackets, and triangles at the 3A Array in preparation for the delivery of the IROSA solar arrays onSpaceX CRS-26 in November. The astronauts also tied back insulation on S6 soDextre can replace the Battery Charge Discharge Modules at this location which have shown signs of decay and will be replaced at a later date. As a get ahead the astronauts photographed a worn keel pin cover which has come loose on one of the pins that were used to secure the airlock in the shuttle bay when it was launched. NASA astronautVictor Glover was Ground IV.^[296]^[297]
248.	Expedition 66 EVA 4	Raja Chari Matthias Maurer	23 March 2022 12:32	23 March 2022 19:26	6 hours, 54 minutes
248.	Expedition 66 EVA 4	The astronauts installed ammonia jumpers on the P1 Truss and repositioned a radiator beam valve module which had been giving them trouble returning the unit to operation. The astronauts routed cables, installed cable clamps on theBartolomeo platform, tied back thermal insulation on theKibo Exposed Facility Berthing Mechanism, replaced Camera 8 on the truss which has a bad filter and light, outfitted the radiator grapple bars for a future spacewalk, and also did other maintenance task outside the station. Because of time the task to break torque on the P4 electronics boxes was moved to a later spacewalk along with the truss cable routing.^[298]^[299]^[300]

249.	Expedition 67 EVA 1 ^	Oleg Artemyev Denis Matveev	18 April 2022 13:01	18 April 2022 21:37	6 hours 37 minutes
249.	Expedition 67 EVA 1 ^	Third spacewalk in a series to activateNauka andPrichal and to commissionERA. During the spacewalk the cosmonauts removed covers and installed electrical cables and an electrical panel to activateERA at the end of the spacewalk. They also installed handrails, and a payload adapter to allow payloads to be transferred to theRussian Segment.^[301]^[302]^[303]
250.	Expedition 67 EVA 2 ^	Oleg Artemyev Denis Matveev	28 April 2022 14:58	28 April 2022 22:40	7 hours 42 minutes
250.	Expedition 67 EVA 2 ^	Fourth spacewalk in a series to activateNauka andPrichal and to commissionERA. During the spacewalk the cosmonauts jettisoned thermal covers, released launch locks, and walked off the arm to its stowage point at worksite 2 on the forward face of the lab where it was latched in place. Because of time they did not release the grapple at worksite 1 and the arm is bent over the solar arrays. The cosmonauts also installed handrails onNauka and the arm and deployed a banner forVictory Day on the side of the station. ERA was checked out inside and attempts to grapple at worksite 3 were unsuccessful. The arm was backed off and parked to get the hands out of the way of docked operations andNauka's thrusters and solar arrays. On the next spacewalk,Samantha Cristoforetti will troubleshoot the arm before it is re-grappled to worksite 3 and moved to its final location at worksite 4. During the spacewalk, a cable which was deployed during Russian EVA 51 back in January got snagged and caused issues with the KURS antennas onPrichal, which forcedSoyuz MS-21 to be flown in manually.

251.	Expedition 67 EVA 3 ^	Fifth spacewalk in a series to outfitNauka and to commissionERA. Russian cosmonaut Oleg Artemyev and Italian astronaut Samantha Cristoforetti worked on theERA robotic arm as part of the work scheduled to commission theNauka module and robotic arm. They launched two Tsiolkovsky-Ryazan (No. 1-2) and eight YUZGU-55 (No. 5-12) satellites, installed anERA grapple point onPoisk to facilitate future relocation of the experiment airlock on the next spacewalk, translated a work platform over toNauka, reconfiguredERA and set the control panel from "grapple mode" to "stowed", replaced a camera port window onERA that prevented grappling on the previous spacewalk, replaced MLI blankets onNauka that were knocked loose by the thruster firings when the module arrived, and installed retainers on Strela 1 onPoisk. The final task to relocate Strela 2 onZarya over toPoisk and install its retainer was deferred to the next EVA as the spacewalkers were running heavily behind schedule due to a later-than-planned start. Cristoforetti became the first female European astronaut to perform a spacewalk, and only the third woman to perform a spacewalk using the Russian Orlan spacesuit (afterSvetlana Savitskaya andPeggy Whitson).^[308]^[309]^[310]^[311]

252.	Expedition 67 EVA 4 ^	Sixth spacewalk in a series to outfitNauka and to prepare the Russian Segment for module transfers which will take place in the fall. The primary task to install cameras on the elbow joint was completed on time and both cameras passed their telemetry checkouts. The final tasks to relocate theERA control panel, set the arm back to "grapple mode", and remove the launch rings from the wrist ofERA will be moved to the next spacewalk. Artemyev was in the process of removing the launch ring at worksite 2 fromERA when he suffered a voltage drop in his spacesuit batteries.Mission Control Moscow ordered him back inside the airlock where he connected to internal power to recharge his suit. Because they were ahead and then behind the timeline, in light of the battery issue Mission Control Moscow gave the order to terminate the EVA at 16:34 GMT and the spacewalk concluded at 17:54 GMT, 4 hours and 1 minute into the spacewalk.^[312] Artemyev was never in any danger and they will be replacing the battery before the next spacewalk. Because of the early EVA termination, the getahead task to relocate Strela 2 over toPoisk was also moved to the next spacewalk along with the other tasks.^[313]^[314]^[315]^[316]
