This list contains all spacewalks performed since the beginning of 2015 where an astronaut has fully, or partially left the spacecraft.[1]
As of 19 August 2016, 215 astronauts have made spacewalks (out of 549 people who have gone into Earth orbit).[2] [3] [4] [5]
Since 1981, NASA has measured spacewalk duration from when the suits went to internal power until the start of airlock re-pressurization. Roscosmos and China have always used the time from hatch opening to hatch closure. These charts typically follow the agency's measurements of spacewalk duration, because those figures tend to be the most readily available, as they are most often provided by the agency.
Spacewalk beginning and ending times are given in Coordinated Universal Time (UTC).

| 407 | 21 August 12:27 | 6 hours, 32 minutes | 18:59 | Hague and Morgan installed the final International Docking Adapter on the Harmony Module. Task for this spacewalk was identical to Spacewalk 194 and required work by both spacewalkers and Dextre to get the docking port installed in preparation for its test by the Boeing CST-100 Starliner which will occur at the end of October. The crew also routed cables and installed Wi-Fi routers for upcoming experiments.[34] | |||
| 408 | 6 October 11:39 | 7 hours, 1 minute | 18:40 | This spacewalk was the first of Expedition 61 and the first of a series of 5 to replace and improve ISS batteries on the P6 truss.[35] | |||
| 409 | 11 October 11:38 | 6 hours, 45 minutes | 18:23 | 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 hatch Mission Control Moscow relayed to the crew Alexei Leonov had passed away 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."[36] [37] | |||
| 410 | 18 October 11:38 | 7 hours, 17 minutes | 18:55 | This spacewalk was to be the third of Expedition 61 and the third of a series of five to replace and improve ISS batteries on the P6 truss. Some of the battery swaps were delayed to EVA 222 because of a failure in a Battery Charge Discharge Unit on the P6 Truss taking the 4B battery channel partially offline. Koch and Meir replaced the failed unit and brought it inside. They wrapped up the spacewalk by installing a stanchion on the Columbus Module and routing a cable on the Destiny Lab module.[38] This was the first all-female spacewalk. During the spacewalk President Trump called the station and congratulated Koch and Meir on this milestone.[39] | |||
| 411 | 15 November 11:39 | 6 hours, 39 minutes | 18:18 | First of a series of four spacewalks to repair the Alpha 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 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.[40] | |||
| 412 | 22 November 12:02 | 6 hours, 33 minutes | 18:35 | 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.[41] | |||
| 413 | 2 December 11:31 | 6 hours, 2 minutes | 17:33 | 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 in Houston, Huntsville, and at CERN 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.[42] |
Spacewalk beginning and ending times are given in Coordinated Universal Time (UTC).

|---|---|---|---|---|---|---|---|
| 414 | 15 January 11:35 | 7 hours, 29 minutes | 19:04 | 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 will replace the camera between spacewalks and will head back out to replace the final three batteries on the next spacewalk.[43] | |||
| 415 | 20 January 11:35 | 6 hours, 58 minutes | 18:33 | 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 on HTV-9 where they will be incinerated on reentry. Koch and Meir finished the day by sending down a message to commemorate Martin Luther King Jr. Day. This spacewalk moved Koch up to third place and Meir up to fourth place on the all-time female spacewalker list.[44] | |||
| 416 | 25 January 12:04 | 6 hours, 16 minutes | 18:20 | 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 contacted CERN 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 the NASA TV cameras used to film the spacewalk.[45] | |||
| 417 | 26 June 11:32 | 6 hours, 7 minutes | 17:39 | Behnken and Cassidy removed five of six nickel-hydrogen batteries for one of two power channels for the starboard 6 (S6) truss, installed two of three new lithium-ion batteries, and installed two of three associated adapter plates that are used to complete the power circuit to the new batteries.[46] | |||
| 418 | 1 July 10:13 | 6 hours, 1 minute | 16:14 | Behnken and Cassidy removed the last of six nickel-hydrogen batteries for disposal. They also connected the last of the three lithium-ion batteries and its adapter plate to complete the circuit to the new battery for the starboard 6 (S6) truss.[47] | |||
| 419 | 16 July 11:10 | 6 hours | 17:10 | Cassidy and Behnken replaced batteries that provide power for the International Space Station's solar arrays on the starboard truss of the complex. They removed six aging nickel-hydrogen batteries, and installed three new lithium-ion batteries that are more efficient. This work nearly completes a three-and-a-half-year effort to upgrade the International Space Station's power system.[48] | |||
| 420 | 21 July 11:12 | 5 hours, 29 minutes | 16:41 | Cassidy and Behnken installed a protective housing with two robotic external leak locator units (RELL). They also removed two lifting fixtures at the base of the station's solar arrays. They then prepared for the installation of the Nanorax airlock, arriving in November. Finally, they routed Ethernet cables and removed a lens filter cover from an external camera.[49] | |||
| 421 | 18 November 15:12 | 6 hours, 47 minutes | 21:59 | The first spacewalk from the Poisk module. Ryzhikov and Kud-Sverchkov completed the first set of tasks to prepare for the decommissioning, undocking, and disposal of the Pirs module, and for the arrival of a new Russian research module called Nauka. The work completed included an attempted replacement of a flow control regulator panel on the Functional Cargo Block (FGB) module, re-routing cables, retrieving hardware that measures space debris impacts, repositioning an instrument used to measure the residue from orientation thruster firings, and removing an experiment. The cosmonauts were unable to replace the flow control regulator panel because a bolt would not release on the transfer container of the new regulator.[50] |

|---|---|---|---|---|---|---|---|
| 439 | 19 January 12:17 | 7 hours, 11 minutes | 19:28 | Spacewalk to configure Prichal to support visiting vehicles. The EVA (Russian EVA-51) was the first of six spacewalks over 2022 to fully integrate Nauka into the ISS.[66] | |||
| 440 | 15 March 12:11 | 6 hours, 54 minutes | 19:06 | First spacewalk to install the IROSA mounting brackets on the S4 Truss. Tasks included installing the struts, mounting brackets, and triangles at the 3A Array in preparation for the delivery of the IROSA solar arrays on SpaceX CRS-25 at the end of May. The astronauts also tied back insulation on S6 so Dextre can replace the Battery Charge Discharge Modules at this location which has 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.[67] [68] [69] | |||
| 441 | 23 March 12:32 | 6 hours, 54 minutes | 19:26 | The astronauts will install and vent ammonia jumpers on the P1 Truss and reposition a radiator beam valve module which has been giving them trouble. The astronauts will also route cables, install cable clamps on the Bartolomeo platform, tie back thermal insulation on the Kibo Exposed Facility Berthing Mechanism, break torque on the P4 electronics boxes, replace Camera 8 on the truss which has a bad filter and light, outfit the radiator grapple bars for a future spacewalk, and also do other maintenance task outside the station.[70] | |||
| 442 | 18 April 15:01 | 6 hours, 37 minutes | 21:37 | Third spacewalk in a series to activate Nauka and Prichal and to commission ERA. During the spacewalk the cosmonauts will remove covers and install electrical cables so ERA can be activated at the end of the spacewalk. They will also install handrails, experiments, and work platforms outside, and break torque on bolts that secure ERA to the lab.[71] | |||
| 443 | 28 April 14:58 | 7 hours, 42 minutes | 22:40 |  Oleg Artemyev Denis Matveev | Fourth spacewalk in a series to activate Nauka and Prichal and to commission ERA. 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 on Nauka and the arm and deployed a banner for Victory Day on the side of the station. ERA will be checked out inside before it moved remotely to its grapple point at worksite 3 where it will be secured until the next spacewalk when it will be moved to worksite 4. During the spacewalk a cable got snagged which was deployed during EVA 50 back in January which caused issues with the KURS antennas on Prichal which forced Soyuz MS-21 to be flown in manually. Artemyev tied down the cables with wire ties and the antenna was redeployed into a safe configuration.[72] [73] [74] [75] | ||
| 444 | 21 July 14:50 | 7 hours, 5 minutes | 21:55 | Oleg Artemyev Samantha Cristoforetti | Russian cosmonaut Oleg Artemyev and Italian astronaut Samantha Cristoforetti worked on the ERA robotic arm as part of the work scheduled to commission the Nauka module and robotic arm. They launched two Tsiolkovsky-Ryazan (No. 1-2) and eight YUZGU-55 (No. 5-12) satellites, installed an ERA grapple point on Poisk to facilitate future relocation of the experiment airlock on the next spacewalk, translated a work platform over to Nauka, reconfigured ERA and set the control panel from grapple mode to stowed, replaced a camera port window on ERA that prevented grappling on the previous spacewalk, replaced MLI blankets on Nauka that were knocked loose by the thruster firings when the module arrived, and installed retainers on Strela 1 on Poisk. The final task to relocate Strela 2 on Zarya over to Poisk and install its retainer was deferred to the next spacewalk because they ran out of time and they had a late start. Cristoforetti become the first female European astronaut to perform a spacewalk, and only the third woman to perform a spacewalk using the Russian Orlan spacesuit (after Svetlana Savitskaya and Peggy Whitson).[76] [77] [78] [79] | ||
| 445 | 17 August 13:53 | 4 hours, 1 minute | 17:54 | Oleg Artemyev Denis Matveev | Sixth spacewalk in a series to outfit Nauka 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 the ERA control panel, set the arm back to "grapple mode", and remove the launch rings from the wrist of ERA will be moved to the next spacewalk. Artemyev was in the process of removing the launch ring at worksite 2 from ERA 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.[80] 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 to Poisk was also moved to the next spacewalk along with the other tasks.[81] [82] [83] [84] | ||
| 446 | 1 September, 10:26 | 6 hours, 7 minutes | 16:33 |  Chen Dong Liu Yang | Fifth EVA from the Tiangong space station and first EVA from Wentians airlock. Taikonauts installed an extended pump set on the exterior of Wentian, raised panoramic camera B, installed an exterior workbench, and tested procedures for an emergency return to the station.[85] | ||
| 447 | 2 September 13:25 | 7 hours, 47 minutes | 21:12 | Oleg Artemyev Denis Matveev | Seventh in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers completed the task that were moved from the previous two spacewalks and installed two payload adapters on Nauka. Because of time and the lack of consumables the task to break torque on bolts that secure the airlock and the radiator to Rassvet was deferred to the next spacewalk. This was the longest EVA of Expedition 67 and the final one of this mission.[86] [87] [88] | ||
| 448 | 17 September 05:35 | 4 hours, 12 minutes | 09:47 | Chen Dong Cai Xuzhe | Sixth EVA from the Tiangong space station. Taikonauts completed the installation of foot restraints and extravehicular workbenches with support from the station's small robotic arm, performed further work on the extended pump set, and further verified EVA emergency rescue procedures.[89] | ||
| 449 | 15 November 14:14 | 7 hours, 11 minutes | 21:25 |  Josh Cassada Frank Rubio | Cassada and Rubio installed the final IROSA mounting bracket on the S6 Truss at Array 1B. As part of get-ahead tasks, they prepared the 3A mounting bracket at P4 for the delivery of 2 IROSAs on the 18th and routed cables along the truss to be mated at the end of EVA 3. Because of time the they did not install the slip collars on S6 and the cable routing was partly completed. The S6 cables will be routed on a later spacewalk when IROSA arrives.[90] [91] [92] | ||
| 450 | 17 November 03:16 | 5 hours, 34 minutes | 08:50 | Chen Dong Cai Xuzhe | Seventh EVA from the Tiangong space station. Taikonauts installed an inter-chamber connection device between Tianhe and Mengtian, raised panoramic A on Wentian, and installed a small mechanical arm power-assisted handle.[93] | ||
| 451 | 17 November 14:39 | 6 hours, 25 minutes | 21:07 | Eighth in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers change a grapple fixture so the airlock can be used as a base point for the arm, broke torque on bolts that secure the airlock and radiator to Rassvet, removed launch restraints from the radiator, vented nitrogen jumpers, replaced a retainer on Strela 2 with one that has a stop, and transferred a MLM outfitting work platform called the SKKO that is, the Nauka Means of attachment of large payloads over to Nauka and installed it at the ERA base point facing aft where ERA use to be when it was launched.[94] [95] [96] | |||
| 452 | 3 December 12:16 | 7 hours, 5 minutes | 19:21 | Assisted by Canadarm 2, Cassada and Rubio installed an IROSA at Array 3A and connected it to the US power system. The spacewalkers undid bolts and installed cables and at 17:37 GMT the array was deployed and is receiving power. As part of get-ahead tasks, they prepared the 4A array for the next spacewalk, demated the 1B array, broke torque on the P4 electronic boxes, and installed cables along the truss to be mated at the end of EVA 5. Spacewalk faced a delay when Cassada's suit did not power up. Troubleshooting steps were done and power was restored to Cassada's suit so they could continue the spacewalk. Nick Hague was ground IV.[97] [98] | |||
| 453 | 22 December 13:19 | 7 hours, 8 minutes | 20:27 | Assisted by Canadarm 2, Rubio and Cassada will install the fourth IROSA at Array 4A. Tasks include releasing bolts, installing cables, and deploying the array and connecting it to the US power system. Once these task are complete Rubio and Cassada will stow the array stowage beams on the carrier and remove their foot restraints from the arm in perpetration for astronaut Nicole Mann to grapple the carrier and load it into the trunk of SpaceX CRS-26 for disposal. If they have time they will photograph Soyuz MS-22 which has suffered a cooling leak in its primary radiator. |

| 454 | 20 January 13:14 | 7 hours, 21 minutes | 20:35 | First spacewalk of 2023 to finish installation of the IROSA mounting brackets on the starboard side of the station. Wakata and Mann installed cables on the 1B Array at the S6 truss, which was not completed on the last spacewalk, tightened bolts and installed a terminator on a cable along with its connected jumper on the SSDCDC converter box to isolate the 1B array until the IROSA solar arrays are installed following the arrival of SpaceX CRS-28 in June. They also assembled and installed the IROSA mounting bracket onto the 1A array, which was also left incomplete on the last spacewalk. Wakata and Mann were unable to secure the final strut on the 1A solar array because of debris in the guide track of the mounting pad and only one of the jumpers was installed. The astronauts returned the strut to the Quest Airlock and will use special tools to clean the tracks before it is remounted on the next spacewalk. They were also unable to connect the cables for 1A due to time constraints. NASA astronaut Zena Cardman was Ground IV, assisted by JAXA astronaut Akihiko Hoshide, who was the Capcom for the astronauts inside the ISS during the spacewalk.[99] [100] [101] | |||
| 455 | 2 February 12:45 | 6 hours, 41 minutes | 19:26 | Final spacewalk to install the mounting brackets for the 1A solar array in preparation for the delivery of IROSA on SpaceX CRS-28. Tasks included installing the final strut, securing the bolts on the 1A solar array, relocating foot restraints that were left on P6 inboard, and routing cables. NASA astronaut Zena Cardman was Ground IV.[102] [103] | |||
| 456 | 9 February 9:10 | 7 hours, 6 minutes | 16:16 | Eighth EVA from the Tiangong space station. Tasks included the installation of a fourth external pump (Z01-04) on Mengtian and other tasks related to Mengtians payload airlock. | |||
| 457 | 2 March ~09:00 | ~7 hours, 49 minutes | ~16:50 | Ninth EVA from the Tiangong space station. Tasks completed were not revealed publicly and no announcement was given prior to the spacewalk. Rumors suggest it took place on February 28, but no date was officially given. Taikonauts installed electrical equipment, according to some Chinese-language sources. | |||
| 458 | 30 March ~09:00 | ~7 hours, 30 minutes | ~16:30 | Tenth EVA from the Tiangong space station. Tasks completed were not revealed publicly and no announcement was given prior to the spacewalk. Rumors suggest it took place on March 30, but no date was officially given. Taikonauts installed and connected cables across the cabin. | |||
| 459 | 15 April ~09:00 | ~7 hours, 30 minutes | ~16:30 | Eleventh EVA from the Tiangong space station. Tasks completed were not revealed publicly and no announcement was given prior to the spacewalk. Rumors suggest it took place on 15 April, but no date was officially given. Taikonauts disposed of trash bags, completed the installation of the fifth extended pump (Z02-01) set on Mengtian, installed and connected cross-cabin cables, and installed the external load exposure platform and support brackets for later science and technology experiments.[104] | |||
| 460 | 19 April 01:40 | 7 hours, 55 minutes | 09:35 | Ninth in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers used ERA to pick up the radiator with the arm where it was relocated at the end of the spacewalk. They spacewalkers closed valves on the nitrogen jumpers, removed covers over the nitrogen jumpers, disconnected the radiator heater cable and capped it, removed bolts and launch restraints, and transferred the radiator over to Nauka and installed it into a socket on the forward face where it will be deployed at the end of EVA 4. As part of get-ahead tasks, they will prepared the airlock for transfer to Nauka on the next spacewalk and stowed the ERA adapter on the airlock. Because of time and issues with matting the radiator the task to jettison the covers was moved to the next spacewalk. This was the longest spacewalk of this expedition and a critical one to get the lab activated.[105] | |||
| 461 | 28 April 13:11 | 7 hours, 1 minute | 20:12 | Bowen and Al Neyadi, who become the first Arab astronaut to perform a spacewalk, finished routing cables and secured the struts with MLI at the 1B and 1A solar arrays in preparation for the arrival of the IROSA arrays in June. The primary task to retrieve the Space to Ground Antenna (SASA) was deferred to the next spacewalk because a stuck bolt on the electronics box prevented the antenna from being released from the FRAM. NASA Astronaut Anne McClain was Ground IV CAPCOM.[106] [107] [108] | |||
| 462 | 4 May 20:00 | 7 hours, 11 minutes | 03:11 | Tenth in a series of spacewalks to outfit Nauka and to prepare ERA for operations. The spacewalkers removed bolts, removed covers, disconnected cables, and used ERA to transfer the airlock over to Nauka where it was installed on the forward facing port. Once the airlock was installed they mated cables and jettisoned their trash which included hardware and covers from the previous spacewalks and this spacewalk. Spacewalk faced a delay when ERA entered an uncontrolled roll placing the airlock out of alinement. Prokopyev and Petelin improvised with a little elbow grease and got the airlock rotated into the correct position and got it latched in place. Spacewalk faced another delay when tape was found on the electrical connectors requiring Prokopyev to cut it before the cables were connected.[109] [110] [111] [112] | |||
| 463 | 12 May 15:47 | 5 hours, 14 minutes | 23:01 | Eleventh and final spacewalk to outfit Nauka and to prepare ERA for operations. To wrap up work on Nauka, the cosmonauts deployed the radiator, and installed nitrogen and ammonia jumpers to cool the Russian Segment and connected the radiator to electrical power, hydraulics, and mechanical connections. As a getahead task while the radiator was being filled with coolant the cosmonauts installed gap spanners on ERAs boom to allow for translation on future spacewalks.[113] [114] | |||
| 464 | 9 June 13:15 | 6 hours, 3 minutes | 19:18 | NASA astronauts Steve Bowen and Woody Hoburg exited the station’s Quest airlock and installed an upgraded IROSA (International Space Station Roll-Out Solar Array) on the 1A power channel on the starboard truss of the station. Tasks included removing bolts, deploying the rollers, and installing cables before the solar array was picked up by Hoburg with assistance from Canadarm 2 and installed on the 1A solar array on the S4 Truss. The array was deployed at 16:32 hours, and is receiving power.[115] [116] | |||
| 465 | 15 June 12:42 | 5 hours, 35 minutes | 18:17 | NASA astronauts Steve Bowen and Woody Hoburg exited the station’s Quest airlock to install the final upgraded IROSA (International Space Station Roll-Out Solar Array) on the 1B power channel on the starboard truss of the station. Tasks included removing bolts, deploying the rollers, and installing cables before the solar array was picked up by Hoburg with assistance from Canadarm 2 and installed on the 1B solar array on the S6 Truss. The array was deployed at 16:51 hours, and is receiving power. As part of getahead task they covered the cables in MLI and secured the struts, relocated their foot restraints inboard, and stowed the support beams on the flight support structure for disposal.[117] [118] | |||
| 466 | 22 June 14:24 | 6 hours, 24 minutes | 20:48 | Prokopyev and Petelin exited the Poisk airlock and routed an Ethernet cable to the port experiment frame on the Zvezda Service Module, jettisoned experiment hardware including the TMTC Monoblock antennas, the highspeed data transmission antenna, and the Seismo Prognos payload, installed a data transmission radio onto the port frame, removed experiments from the Zvezda Service Module, photographed Zvezda including the thrusters so they can patch the leak, inspected an antenna, and retrieved the Biorisk containers. As a getahead they cleaned the windows on the Russian segment, repositioned the Plume Measurement Unit, and jettisoned a towel.[119] [120] | |||
| 467 | 20 July 05:45 | 7 hours, 55 minutes | 13:40 | Twelfth EVA from the Tiangong space station. Taikonauts installed & lifted the bracket for Tianhe panoramic camera B and unlocked & lifted panoramic camera A/B on Mengtian. Zhu Yangzhu became first Chinese flight engineer to conduct an extravehicular activity.[121] The EVA set a new duration record for a Chinese spacewalk. | |||
| 468 | 9 August 14:44 | 6 hours, 35 minutes | 21:19 | Twelfth and final spacewalk to outfit Nauka and to prepare ERA for operations. Both cosmonauts ventured outside the station’s Poisk Airlock to attach three debris shields to the Rassvet module. They also tested the sturdiness of the last MLM outfitting called the ERA portable workpost, that will be affixed to the end of the European robotic arm attached to the Nauka multipurpose laboratory module.[122] [123] [124] | |||
| 469 | 25 October 17:49 | 7 hours, 41 minutes | 01:30 (next day) | The cosmonauts ventured outside and installed a mini radar experiment on Nauka, launched a CubeSat which will test solar sails, and photographed the RTOd radiator and closed valves to isolate the radiator and vented residual coolant so plans can be done to fix a leaking cooling line that delayed two US spacewalks. During one of the vents, Kononenko got sprayed and the coolant got on one of his tethers. The tether was placed in a trash bag and stowed externally to decontaminate it, while Kononenko's suit was wiped down to prevent coolant from entering the station. During the radar deployment, one of the hinges got stuck. The cosmonauts will go out on the next spacewalk with a pole and lock the hinges so it can be deployed. During the satellite deployment, the telescoping booms did not come out and ground controllers are working to manually deploy them so the satellite can track the sun.[125] [126] [127] | |||
| 470 | 1 November 12:05 | 6 hours, 42 minutes | 18:47 | Moghbeli and O'Hara ventured outside and removed an H fixture from the 3B mass canister on the P4 truss in preparation for the arrival of the struts and the IROSA solar arrays in 2025. They also replaced a damaged Trundle Bearing under Cover 2 which had been giving them trouble in the past and greased the tracks before the new Trundle Bearing was installed on the port SARJ, secured a cable on Camera 8 which was shorting out a light used for dockings, and released wedge clamps on the SASA antenna. The primary task to retrieve the SASA antenna from ESP2 so it can be returned to Earth on SpaceX CRS-29 was moved to the next spacewalk because of issues removing the covers from the SARJ. O'Hara was not secured properly during the removal and had to be assisted by Moghbeli to get the cover stowed. During the spacewalk, the bag containing the grease gun was lost, but the tools were not needed and the bag posed no collision risk to the station. This was the fourth all-female spacewalk on the station, following Christina Koch and Jessica Meir's three spacewalks during Expedition 61.[128] [129] [130] | |||
| 471 | 21 December 06:10 | 7 hours, 25 minutes | 13:35 | Thirteenth EVA from the Tiangong space station. Tasks included a repair test of the Tianhe core module's solar panels, which have sustained minor damage caused by impacts of space debris and micrometeoroids.[131] |
