|1||21.12.2013||R. Mastracchio||5h 28m||
The EVA mainly focused on disconnecting the failed loop A pump module from its location on the Starboard 1 (S1) Truss - including the infamously difficult ammonia disconnections.
|2||25.12.2013||R. Mastracchio||7h 30m||
They removed a spare pump module from the ESP-3 and installed it on the Starboard 1 (S1) Truss.
|3||27.01.2021||V. Glover||6h 56m||
This spacewalk focused on completing cable and antenna rigging for the "Bartolomeo" science payloads platform outside the ESA (European Space Agency) Columbus module. The duo also configured a Ka-band terminal, known as COL-Ka, that will enable an independent, high-bandwidth communication link to European ground stations. Bartolomeo is partially operational and in a safe configuration following the connection of four of six cables to the science platform, and the final two cables that could not be connected will be attended to on a future spacewalk. After completing the upgrades on the Columbus module, the astronauts removed a grapple fixture bracket on the far port (left) truss in preparation for future power system upgrades. Victor Glover also worked to replace a suspected broken pin inside the station's airlock as a "get ahead" task, but teams determined that a replacement pin was not needed after an inspection confirmed the current pin to be functioning properly.
|4||01.02.2021||V. Glover||5h 20m||
This spacewalk addressed a variety of tasks, including installation of a final lithium-ion battery adapter plate on the port 4 (P4) truss that wrapped up battery replacement work begun in January 2017. They replaced an external camera on the starboard truss, installed a new high-definition camera on the Destiny laboratory, and replaced components for the Japanese robotic arm's camera system outside the Kibo module.
|5||13.03.2021||V. Glover||6h 47m||
They vent and relocated ammonia jumper cables, installed a structural "stiffener" on the airlock thermal cover, and completed the connection of payload cables on the new Bartolomeo platform on the Columbus module. Other tasks included the replacement of a wireless communications antenna on the Unity module.
