This spacewalk focused on completing cable and antenna rigging for the "Bartolomeo" science payloads platform outside the ESA Columbus module. The duo also configured a Ka-band terminal, known as COL-Ka.

Main tasks were the 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 began assembling and installing modification kits required for upcoming solar array upgrades.

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.
