Expedition 75: Menon & Adenot on Spacewalk | International Space Station
Spacewalkers Anil Menon of NASA (red stripes) and Sophie Adenot of the European Space Agency (ESA) installed a high-speed antenna on the station while soaring 260 miles above Earth on Tuesday, Aug. 25, 2026. They also pictured the SpaceX Dragon (Image#2) and the Alpha Magnetic Spectrometer (Image#8), a cosmic particle detector. NASA astronaut Anil Menon and ESA astronaut Sophie Adenot concluded their spacewalk outside the International Space Station at 2:57 p.m. EDT.
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.
