French astronaut Sophie Adenot and U.S. astronaut Anil Menon completed a spacewalk Tuesday to install a new communications antenna on the International Space Station [1].
The upgrade ensures stable and efficient data transmission between the orbiting laboratory and mission control in Houston. Maintaining these links is critical for the safety of the crew, and the success of ongoing scientific research conducted in microgravity.
This second extravehicular activity took place on Aug. 25, 2026 [1]. The mission served as the conclusion to a series of tasks that began approximately one week earlier [1]. During the outing, Adenot and Menon worked together to secure the hardware required for the antenna's operation.
The pair exited the station to finalize the installation process, marking a successful end to the objectives set during the previous week's mission [1]. The operation required precise coordination between the astronauts outside the station and the support teams on the ground.
While the specific technical specifications of the antenna were not detailed, the installation is part of a broader effort to modernize the aging infrastructure of the ISS. The station continues to rely on a complex network of antennas to maintain contact with Earth across various frequency bands.
Adenot's participation in the EVA highlights the ongoing international collaboration that defines the ISS program. The mission involved coordination between the European Space Agency and NASA to ensure the hardware was correctly positioned for optimal signal strength [1].

The successful installation of the communications antenna reduces the risk of signal degradation between the ISS and Houston. As the station ages, replacing legacy hardware is essential to prevent communication gaps that could jeopardize emergency responses or the transmission of high-bandwidth scientific data.
