NASA astronaut Jessica Meir and European Space Agency (ESA) astronaut Sophie Adenot are set to conduct the sixth all-female spacewalk outside the International Space Station (ISS) on September 1. The event is scheduled to begin at approximately 8:30 a.m. EDT (1230 GMT) and is expected to last around 6.5 hours. Live coverage will be available through Space.com and NASA's official channels, with coverage starting at 7:00 a.m. EDT (1100 GMT). During the spacewalk, Meir and Adenot will perform several key tasks. They will replace a retroreflector on the ISS’s Harmony module, which helps spacecraft navigate during docking. They will also install jumper cables for data-relay systems, prepare the Alpha Magnetic Spectrometer’s radiator for future maintenance, and replace a high-definition camera on the station’s truss. The Alpha Magnetic Spectrometer is a $2 billion particle physics experiment designed to study cosmic rays and search for dark matter, a mysterious form of matter that does not emit light but exerts gravitational pull. Adenot will be designated as "crew member 1" and will wear a spacesuit with red stripes, while Meir will be "crew member 2" in a standard, unmarked suit. This will be Adenot’s third spacewalk, making her the first French woman to perform an extravehicular activity (EVA), or spacewalk. For Meir, this will be her seventh spacewalk, placing her third among female NASA astronauts, behind Peggy Whitson (10 EVAs) and Suni Williams (nine). Meir has already participated in three all-female spacewalks, including previous missions with NASA astronaut Christina Koch in 2019 and 2020. To date, there have been only five all-female spacewalks at the ISS, highlighting the significance of this event. In a related development, a photo from August 25, 2026, shows Adenot outside the ISS during a spacewalk with NASA astronaut Anil Menon to replace a Space-to-Ground antenna. This was the second spacewalk for the pair in the antenna replacement mission. During their first spacewalk a week earlier, they were unable to complete the installation due to time constraints, but Adenot still became the first French woman to conduct an EVA.
