On August 18, 2026, ESA astronaut Sophie Adenot became the first French woman to perform a spacewalk. This mission, designated as U.S. Spacewalk 97, marked a significant milestone in space exploration. Adenot worked alongside NASA astronaut Anil Menon to replace a failed antenna on the International Space Station.
While the historic nature of this event is clear, the mission also provided a lesson in the realities of orbital maintenance. The primary objective involved removing an old Space-to-Ground antenna and installing a new unit on the Z1 truss. This specific hardware had stopped tracking data-relay satellites back in November. Despite a clear plan, the task proved more difficult than simulations suggested.
The crew encountered difficulty disconnecting electrical cables and loosening bolts while working in pressurized suits. These mechanical obstacles consumed more time than the flight controllers had budgeted for the outing. As the clock governing the suit's life support systems ticked down, Mission Control decided to prioritize safety over completing the installation.
The decision to defer the antenna replacement prevented the crew from pushing into hazardous territory. Adenot and Menon successfully secured the failed unit, ensuring the station remained stable. Because a second antenna continues to handle high-speed data links, the station faces no operational degradation. The team plans to complete the installation during a follow-up spacewalk scheduled for August 25.
This incident highlights how space operations function. Contingency planning is a core component of mission design, and the crew followed their fallback protocols. Adenot credited the ground teams who prepared those responses. The event serves as a reminder that complex hardware often dictates the pace of work regardless of the initial schedule.
