NASA has set a general return window for French astronaut Sophie Adenot, with her return to Earth depending on the successful launch of the Crew-13 mission in early October. On September 17, NASA released a progress report stating that the four astronauts of the Crew-13 mission have entered quarantine at the Johnson Space Center in Houston in preparation for a launch to the International Space Station (ISS). The departure of Crew-12, which includes Sophie Adenot, is contingent on the successful launch of Crew-13. Sophie Adenot, an astronaut with the European Space Agency (ESA), arrived at the ISS on February 14, 2026, the day after her launch aboard a SpaceX Dragon capsule. Her mission, named Epsilon, marks the first flight of a French astronaut to the ISS since Thomas Pesquet’s Alpha mission in 2021. Adenot is the second French person to join an ISS crew, following Claudie Haigneré, who did so 25 years earlier. During her stay, which was initially planned to last nine months, she was to participate in over 200 scientific experiments and conduct three extravehicular activities (EVA), one of which was entirely female. Even though her mission was shortened by a month, it remains the longest ever assigned to an ESA astronaut. The duration of the Crew-12 mission was reduced from nine to seven months, which was expected to result in a return flight in September. However, a leak detected on the Dragon capsule delayed the timeline, allowing Adenot to extend her stay in orbit. NASA had already adjusted the Crew-13 schedule by the end of August, prior to this quarantine period. As long as Crew-13 has not launched and joined the station, Crew-12 remains aboard. A launch in early October would place Sophie Adenot's return in the first half of the month, allowing for the necessary handover between the two crews. For now, NASA has not specified an exact date for the undocking or splashdown of Crew-12. This will depend on the launch window for Crew-13 (which includes two Americans, one Russian, and one Canadian) and weather conditions, factors that have previously influenced schedules. If all goes according to plan, Sophie Adenot will return to Earth after approximately eight months in orbit at an altitude of 400 kilometers. While she will have "lost" one month of the original nine-month plan, she will have conducted three EVAs in return. At just 44 years old, Adenot has every opportunity to return to space in the future.
