Astronomy:List of spacewalks 2015–2024

Short description: None

This list contains all spacewalks performed between 2015–2024 where an astronaut has fully, or partially left the spacecraft.

As of 19 August 2016, 215 astronauts have made spacewalks (out of 549 people who have gone into Earth orbit).

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.

2015–2019 spacewalks

Spacewalk beginning and ending times are given in Coordinated Universal Time (UTC).

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.
441	23 March 12:32	6 hours, 54 minutes	19:26	Expedition 66 ISS Quest	Raja Chari Matthias Maurer	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.
442	18 April 15:01	6 hours, 37 minutes	21:37	Expedition 67 ISS Poisk	Oleg Artemyev Denis Matveev	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.
443	28 April 14:58	7 hours, 42 minutes	22:40	Expedition 67 ISS Poisk	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.
444	21 July 14:50	7 hours, 5 minutes	21:55	Expedition 67 ISS Poisk	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).
445	17 August 13:53	4 hours, 1  minute	17:54	Expedition 67 ISS Poisk	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. 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.
446	1 September, 10:26	6 hours, 7 minutes	16:33	Shenzhou 14 TSS Wentian	Chen Dong Liu Yang	Fifth EVA from the Tiangong space station and first EVA from Wentian's airlock.

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.
466	22 June 14:24	6 hours, 24 minutes	20:48	Expedition 69 ISS Poisk	Sergey Prokopyev Dmitry Petelin	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.
467	20 July 05:45	7 hours, 55 minutes	13:40	Shenzhou 16 TSS Wentian	Jing Haipeng Zhu Yangzhu	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. The EVA set a new duration record for a Chinese spacewalk.
468	9 August 14:44	6 hours, 35 minutes	21:19	Expedition 69 ISS Poisk	Sergey Prokopyev Dmitry Petelin	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.
469	25 October 17:49	7 hours, 41 minutes	01:30 (next day)	Expedition 70 ISS Poisk	Oleg Kononenko Nikolai Chub	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.
470	1 November 12:05	6 hours, 42 minutes	18:47	Expedition 70 ISS Quest	Jasmin Moghbeli Loral O'Hara	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.
