# Sophie Adenot ISS mission events > Live situation record from CLSTR: https://clstr.news/situations/sophie-adenot-iss-mission-events > Updated: 2026-09-02T23:40:17.000Z. Sources: 99. Developments: 10. On 18 August 2026, ESA astronaut Sophie Adenot made history as the first French woman to conduct an extravehicular activity (EVA) on the International Space Station. Partnering with NASA astronaut Anil Menon, the mission, designated as US Spacewalk 97, lasted approximately six hours and twenty-three minutes. The primary objective was the replacement of the Space-to-Ground antenna (SGANT) on the station’s Z1 truss segment. While the duo successfully dismantled the aging antenna, they were unable to complete the full replacement of the new unit due to stubborn bolts and electrical connectors. On 25 August 2026, Adenot and Menon conducted a second six-and-a-half-hour spacewalk to complete the replacement of the faulty SGANT. The mission was successful; the astronauts installed the new antenna, which is essential for maintaining high-speed data transmission and communications. Initial checks indicated the new antenna is functioning with “good power and data transmission capabilities.” On 31 August 2026, Adenot and NASA astronaut Jessica Meir completed an all-female spacewalk, the sixth such mission in history, lasting approximately six hours and 49 minutes. Serving as the lead spacewalker, Adenot replaced a retroreflector on the Harmony module to assist with spacecraft docking and navigation. The crew also installed jumper cables for data-relay systems, replaced a high-definition camera, and prepared a radiator for the Alpha Magnetic Spectrometer. Additionally, the astronauts collected biological surface samples to search for microorganisms. During the operation, Adenot experienced limited mobility in her left shoulder due to a heater harness snagging on a joint module; the issue was resolved by adjusting the suit and opening a module zipper to free the wiring. This mission marked Adenot’s third spacewalk in two weeks and Meir’s seventh. ## Claims - Adenot became the first French woman to perform a spacewalk on August 18. (corroborated by 3 sources) - NASA reported that astronauts Jessica Meir and Sophie Adenot completed a nearly seven-hour spacewalk. (corroborated by 3 sources) - The spacewalk was intended to install a reflector to facilitate spacecraft docking. (corroborated by 3 sources) - Astronaut Sophie Adenot experienced mobility issues in her left arm due to a suspected heater harness snag. (corroborated by 3 sources) - The spacewalk concluded 20 minutes later than scheduled. (corroborated by 3 sources) - The astronauts replaced a high-definition camera and collected an external sample to search for microorganisms. (corroborated by 3 sources) - Mission Control postponed the installation of bolts for the Alpha Magnetic Spectrometer radiator due to delays. (corroborated by 3 sources) - Astronauts Jessica Meir and Sophie Adenot completed the sixth all-female spacewalk in history. (corroborated by 3 sources) - The crew replaced high-definition cameras on the station. (corroborated by 3 sources) - Sophie Adenot described the successful installation of the antenna as a miracle due to mechanical setbacks. (corroborated by 2 sources) - Adenot will lead a third spacewalk on September 1 to replace a retroreflector. (corroborated by 2 sources) - The third spacewalk will be an all-female mission featuring Adenot and Jessica Meir.
