Adenot attended a in Saint-Denis, a secondary school open to girls whose father, grandfather or great-grandfather had been awarded the Legion of Honour, where she obtained her . She then completed to prepare for entry into a .
From 2001 to 2003, she studied engineering at the Institut Supérieur de l'Aéronautique et de l'Espace (ISAE-SUPAERO), specializing in the flight dynamics of aircraft and spacecraft and earned a degree in 2004. That same year, she earned a Master of Science in human factors engineering from the Massachusetts Institute of Technology (MIT). While at MIT, she worked in the Man-Vehicle Laboratory and wrote her thesis on how the vestibular system adapts to artificial gravity, contributing to the development of centrifuge training for astronauts.
After graduating, Adenot spent one year working as an engineer at Airbus Helicopters in Marignane, focusing on the design of helicopter cockpits, particularly for the company's H225 model.
Adenot joined the French Air Force in 2005. After completing helicopter pilot training, she was assigned to Escadron d'Hélicoptères 1/67 Pyrénées at Cazaux Air Base, where she piloted Caracal helicopters on search and rescue missions in hostile environments from 2008 to 2012. In 2008, she applied to the European Space Agency astronaut programme, the European Astronaut Corps, but was rejected. She transferred to the High Authority Transport Squadron based in Villacoublay, which is responsible for transporting the head of state, government ministers, and visiting foreign delegations, in 2012.
In 2017, she entered the école du personnel navigant d'essais et de réception, a test pilot school, and in 2018 became the first female helicopter test pilot in France. After graduating from Empire Test Pilots' School in the United Kingdom in 2018, she worked as a helicopter test pilot at Cazaux Air Base under the French Defence Procurement Agency from 2019 to 2022. , she had accumulated over 3,000 flight hours across 22 different types of helicopters.
Adenot was promoted to the rank of lieutenant in August 2006, captain in 2009, commandant in December 2014, lieutenant colonel in June 2020, and colonel in July 2023.
Adenot was selected to join the European Astronaut Corps as part of the 2022 European Space Agency Astronaut Group. She is the second French woman to join the corps, after Claudie Haigneré. The 2022 class, nicknamed "The Hoppers", was chosen from a pool of 22,500 applicants.
In 2024, ESA announced that Adenot would be the first member of her class to fly to the International Space Station (ISS) for a long-duration mission set for spring 2026. ESA's portion of the Crew-12 missionâÂÂAdenot's assignmentâÂÂwas dubbed "Epsilon". As part of SpaceX Crew-12, Adenot launched to the ISS on 13 February 2026 to join the Expedition 74 crew. She will participate in more than 200 experiments in microgravity during her 8-month stay on the ISS. These experiments include testing a device that allows for autonomous medical ultrasounds, named EchoFinder, to determine the impact of weightlessness on herself and other crew members; an experiment, called PhysioTool, to measure several of the body's physiological factors; and an experiment in partnership with French schools, named ChlorISS, which will observe the impact of light and gravity on the growth of a Arabidopsis thaliana and a Brassica rapa (Mizuna) plant; and testing a prototype of a space suit, the "EuroSuit". She also brought a selection of French dishes, including lobster bisque and foie gras, created by Michelin-starred chef Anne-Sophie Pic to supplement standard onboard meals.
In 2020, Adenot was recognized by the Young Leaders program of the French-American Foundation.
In 2021, she was awarded the for her "actions as an inspiring ambassador for gender equality in sciences". She was appointed a of the French National Order of Merit in 2022. She is a recipient of the country's Aeronautical Medal.
Adenot met her husband during her engineering studies; they have one son as of 2025.
