iss075e0069016 (Aug. 25, 2026) --- ESA (European Space Agency) astronaut and Expedition 75 flight engineer Sophie Adenot is tethered to the International Space Station during a spacewalk to install a high-speed space-to-ground antenna on the Z1 truss segment above the Unity module. Adenot and NASA astronaut and Expedition 75 flight engineer Anil Menon (out of frame) spent six hours and 30 minutes replacing a failed antenna with a spare and making the precise connections needed to activate it for high-speed transmissions with mission control.
