| 22 March 12:01 | 6 hours  39 minutes | 18:40 | Expedition 59 ISS Quest |  Anne McClain  Nick Hague |  connected 3 new Li-ion batteries to replace 6 old Ni-H batteries on power channel 4A of the P4 truss segment.  cleaned up debris on Unity's common berthing mechanism using Kapton tape   secured a tieback for restraints on the solar array blanket box. |
| 29 March 11:42 | 6 hours 45 minutes | 18:27 | Expedition 59 ISS Quest |  Nick Hague  Christina Koch |  connected 3 new Li-ion batteries to replace 6 old Ni-H batteries on power channel 2A of the P4 truss segment.  disconnected cables and relocated an adapter plate to enable Canadarm2 to remove a failed Li-ion battery. |
| 8 April 11:31 | 6 hours 29 minutes | 18:00 | Expedition 59 ISS Quest |  Anne McClain  David Saint-Jacques |  installed jumper cables between the Unity module and the S0 truss to establish redundant power to Canadarm2.  installed cables to provide for more expansive wireless communications coverage outside the orbital complex.  relocated an adapter plate from the 22 March spacewalk in preparation for future battery upgrade operations |
| 29 May 15:42 | 6 hours 1 minute | 21:43 | Expedition 59 ISS Pirs |  Oleg Kononenko  Aleksey Ovchinin |  removed experiments from the Pirs docking compartment and cleaned the windows.  installed a handrail to connect Zarya to Poisk and re-positioned the Plume Measuring Unit.  moved to the Zvesda Service Module and removed and jettisoned the Plasma Monitoring Units.  wished happy birthday to Alexei Leonov who is the first spacewalker and is celebrating his 85th birthday on 30 May. Also brought a picture of Leonov into space with them. |
| 21 August 12:27 | 6 hours 32 minutes | 18:59 | Expedition 60 ISS Quest |  Nick Hague  Andrew R. Morgan |  Hague and Morgan installed the final International Docking Adapter on the Harmony Module. The 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 the Boeing CST-100 Starliner orbital flight test, which will occur by the end of December. The crew also routed cables and installed Wi-Fi routers for upcoming experiments. |
| 6 October 11:39 | 7 hours 01 minutes | 18:40 | Expedition 61 ISS Quest |  Christina Koch  Andrew R. Morgan |  This spacewalk was the first of Expedition 61 and the first in a series of five to replace and improve ISS batteries on the P6 truss. |
| 11 October 11:38 | 6 hours 45 minutes | 18:23 | Expedition 61 ISS Quest |  Andrew R. Morgan  Christina Koch |  This spacewalk was the second of Expedition 61 and the second in a series of five to replace and improve ISS batteries on the P6 truss. Before they went out to the hatch, Mission Control Moscow relayed to the crew that Alexei Leonov had died and that this spacewalk was dedicated to him. As the crew came in and took off their suits, each gave a few words in memory of Leonov before station commander Luca Parmitano said "Farewell Alexei, and ad astra." |
| 18 October 11:38 | 7 hours 17 minutes | 18:55 | Expedition 61 ISS Quest |  Christina Koch  Jessica Meir |  This spacewalk was the third of Expedition 61 and the third in a series of five to replace and improve ISS batteries on the P6 truss. Some of the battery swaps were delayed to EVA 222 due to 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 replaced the failed unit and brought it back inside. The battery swap was moved to EVA 222 to save time and Meir and Koch wrapped up the spacewalk by installing a stanchion on the Columbus Module and tightening the bolts on the S0 Truss, which had come loose. This spacewalk was the first all-female spacewalk. During the spacewalk, President Trump called the station and congratulated Koch and Meir on this milestone. |
| 15 November 11:39 | 6 hours 39 minutes | 18:18 | Expedition 61 ISS Quest |  Luca Parmitano  Andrew Morgan |  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.   This spacewalk marks Parmitano's return to spacewalking after the Water in the Helmet Incident during EVA 171. |
| 22 November 12:02 | 6 hours 33 minutes | 16:35 | Expedition 61 ISS Quest |  Luca Parmitano  Andrew Morgan |  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. |
| 2 December 11:31 | 6 hours 2 minutes | 17:33 | Expedition 61 ISS Quest |  Luca Parmitano  Andrew Morgan |  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. |
