The pair installed brackets and struts to support the future installation of an ISS Roll-Out Solar Array (iROSA).

The duo installed hoses on a Radiator Beam Valve Module that routes ammonia through the station's heat-rejecting radiators to keep systems at the proper temperature. The astronauts also installed a power and data cable on the Columbus module's Bartolomeo science platform, replaced an external camera on the station's truss, and conducted other upgrades to station hardware.
