French astronaut Sophie Adenot conducted her second spacewalk outside the International Space Station on Tuesday to replace a space-to-ground antenna [1, 2].
The mission marks a rapid succession of complex extravehicular activities for Adenot, who recently became the first French woman to perform a spacewalk. Her ability to execute high-stakes technical repairs in a short timeframe demonstrates the increasing operational capacity of European astronauts on the orbital complex.
The excursion lasted six and a half hours [3]. During this time, Adenot worked on the exterior of the station to swap out the antenna, a component essential for maintaining communication between the orbiting laboratory and ground control [2].
This second outing occurred just one week after her first historic spacewalk [1, 4]. The tight window between missions requires significant physical and mental endurance, as astronauts must manage the decompression and acclimation processes necessary for exiting the station's pressurized modules.
Adenot's presence on the ISS is part of a broader effort to diversify the personnel conducting maintenance and scientific research in low Earth orbit. The replacement of the antenna is a routine but critical part of station upkeep, ensuring that telemetry and voice data continue to flow without interruption [2].
The operation was monitored by ground teams who coordinated the movement of tools and the installation of the new hardware. By completing the task, Adenot has solidified her role in the current expedition's technical rotation, a role that requires precise coordination with her crewmates inside the station.

Adenot's rapid return to the station's exterior underscores a shift toward more frequent and diverse crew rotations for complex maintenance. By successfully replacing critical communication hardware within a week of her first outing, she demonstrates the viability of shortened recovery windows for European astronauts, potentially increasing the efficiency of future ISS maintenance schedules.
