Spacewalkers Install High-Speed Antenna | International Space Station

In this image, NASA astronaut Anil Menon is attached to the Canadarm2 robotic arm as it guides him toward the worksite where he and European Space Agency astronaut Sophie Adenot (out of frame) installed a space-to-ground antenna. Menon and Adenot concluded their spacewalk outside the International Space Station at 2:57 p.m. EDT on August 25, 2026.

NASA astronaut Anil Menon: "In front of Dragon is the antenna we installed together." At 8:05 a.m. Eastern Daylight Time (EDT) on October 7, 2026, NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev of Russia undocked from the space-facing port of the International Space Station’s Harmony module aboard their SpaceX Dragon spacecraft.

Expedition 75 Mission Highlights: In the first image, NASA astronaut Anil Menon is attached to the Canadarm2 robotic arm as it guides him toward the worksite where he and European Space Agency astronaut Sophie Adenot (out of frame) installed a space-to-ground antenna. Menon and Adenot concluded their spacewalk outside the International Space Station at 2:57 p.m. Eastern Daylight Time (EDT) on August 25, 2026.

During the 6‑hour, 30‑minute spacewalk, Menon and Adenot successfully installed and connected the spare Space‑to‑Ground antenna, a critical link that enables high‑speed data transmission between NASA’s Mission Control Center in Houston and the orbital complex. Afterward, they secured the failed unit that was removed and temporarily stowed during the duo’s spacewalk on Aug. 18, to a spare‑parts platform on the station’s truss structure.

Initial checkouts of the newly installed antenna showed good power and data transmission. Flight controllers on the ground will continue testing the antenna overnight to ensure full functionality. 

U.S. spacewalk 98 was Menon’s third career spacewalk and the second for Adenot. It also was the 283rd spacewalk in support of space station assembly, maintenance, and upgrades.
