Expedition 66 Flight Engineers Raja Chari of NASA and Matthias Maurer of ESA (European Space Agency) concluded their spacewalk at 3:26 p.m. EDT after 6 hours and 54 minutes in preparation for upcoming solar array installation.

Maurer and Chari completed their major objective for today to install 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 crew members 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. The pair deferred a few secondary tasks, such as torque resets and cable routing, to a future spacewalk.

It was the 248th spacewalk in support of space station assembly, upgrades and maintenance, and was the second in Chari’s career and the first for Maurer. Chari and Maurer are in the midst of a planned six-month science mission living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions as part of NASA’s Moon and Mars exploration approach, including lunar missions through NASA’s Artemis program.
