NASA astronaut Anil Menon and ESA astronaut Sophie Adenot concluded a spacewalk outside the International Space Station at 2:52 p.m. EDT on Aug. 18, 2026, NASA reported. During the 6-hour, 23-minute spacewalk, the pair removed a failed Space-to-Ground antenna and tied the unit down on the station's truss structure.

NASA said disconnecting electrical cables and loosening bolts took longer than expected, delaying work to install a replacement antenna. The agency said that installation was expected to be completed during a future spacewalk. NASA reported that the station continued to operate with a fully functional Space-to-Ground antenna, which supports high-data-rate communications with its Tracking Data and Relay Satellites and control centers worldwide, including Mission Control in Houston.

Mission planners were to discuss the forward plan for work scheduled on the next spacewalk, then planned for Tuesday, Aug. 25, according to the report. NASA described the outing as Menon's second career spacewalk and Adenot's first; it said she is the first French woman to conduct a spacewalk. It was the 282nd spacewalk in support of station assembly, maintenance and upgrades, NASA said.
