Sophie Adenot, a European Space Agency astronaut, conducted her first spacewalk on August 18, 2026, to replace a critical communication antenna on the International Space Station alongside NASA astronaut Anil Menon, according to the European Space Agency.
Sophie Adenot, a French engineer and European Space Agency (ESA) astronaut, made history on August 18, 2026, as she conducted her first spacewalk to replace a vital communication antenna on the International Space Station (ISS). The 6.5-hour extravehicular activity (EVA), carried out with NASA astronaut Anil Menon, was a pivotal moment in her career and a milestone for European women in space exploration. Adenot, who described the EVA as an adventure within the adventure,
was tasked with replacing the Space-to-Ground Antenna (SGANT), a system critical for high-speed data transmission between the ISS and NASA’s Mission Control Center in Houston, Texas, the European Space Agency reported.
Preparation and Personal Reflections
Adenot’s journey to the spacewalk began months before her launch to the ISS. She trained extensively in a swimming pool at ESA’s European Astronaut Centre in Cologne, Germany, and NASA’s Johnson Space Center in Houston, United States, completing over 150 hours of underwater training to simulate microgravity conditions. Adenot also rehearsed procedures using a full-scale ISS model, focusing on safety protocols, tool handling, and communication with her partner and mission control.
Adenot’s spacewalk was not just a technical challenge but also a deeply personal experience. During the EVA, she reflected on the awe of space, saying, When you leave the airlock and tip out into the void, 450 kilometres of nothingness, you need to have a strong heart.
Historical Context and Significance
Adenot’s spacewalk marked a significant milestone for European women in space. She became the second European woman to perform an EVA, following Italy’s Samantha Cristoforetti in 2022, and the second French woman to travel to space after Claudie Haigneré, who flew in 1996 and 2001 but did not conduct an EVA. The mission also highlighted the growing role of international cooperation in space exploration, with the ISS serving as a symbol of collaboration among nations. The European Space Agency emphasized the importance of the SGANT, stating it enables high-speed communication between the Mission Control Center in Houston and the space station,
the agency reported.
The spacewalk was part of a broader effort to maintain the ISS’s operational capabilities. Adenot and Menon spent six and a half hours outside the station, working under the supervision of commander Jessica Meir and flight engineer Jack Hathaway, who operated the Canadarm2 robotic arm from inside the ISS.
Future Implications and Broader Impact
Adenot’s spacewalk not only advanced the ISS’s communication systems but also inspired future generations of astronauts. Adenot’s achievement highlighted the importance of diversity in space exploration, with her success paving the way for more women and underrepresented groups to pursue careers in aerospace.

As Adenot returned to the ISS, her mission served as a testament to the resilience and ingenuity of space explorers. The successful EVA reinforced the critical role of international collaboration in maintaining the ISS and advancing scientific research in space. With future missions on the horizon, Adenot’s journey stands as a reminder of the enduring human spirit to explore the unknown, one step at a time. The European Space Agency emphasized that such efforts are essential for the continued success of space exploration and the safety of astronauts worldwide.
