One of my favorite places to work on @Space_Station is the Life Sciences Glovebox, where we get to be the hands and eyes of scientists on the ground. Here, I’m helping with an experiment called InSPA-Auxilium Bioprinter-Cell Printing, which leverages the microgravity environment of ISS to 3D print cells and manufacture human liver, kidney, and cartilage tissue. Just one of many examples of how we’re using this amazing orbital national laboratory to reshape our understanding of biology, medicine, and engineering, and improve life on Earth!

[🇫🇷 version FR 👇] Today is World Osteoporosis Day. As a woman in my 40s, my bone mass would naturally be expected to start decreasing. Add months in microgravity, where our bones no longer have to support our body weight as they do on Earth, and you might expect that decline to accelerate. The first results are encouraging: after nearly eight months in space, my initial assessments showed no significant change in my bone mass, and even a slight increase in some areas! While there is still much to learn from the data, it’s a powerful reminder of the important role that very targeted exercise, alongside good nutrition, can play in protecting bone health, in space and on Earth! 🎥 @esa Aujourd’hui, c’est la Journée mondiale contre l’ostéoporose. Passée la quarantaine, la masse osseuse tend naturellement à diminuer chez les femmes. Ajoutez à cela plusieurs mois en micropesanteur, un environnement dans lequel les os n’ont pas à supporter le poids du corps, et l’on pourrait s’attendre à ce que cette diminution s’accélère. Les premières évaluations sont encourageantes : après près de huit mois dans l’espace, aucune variation significative de ma masse osseuse, et même une légère augmentation par endroits ! Même s’il reste encore beaucoup à apprendre des données recueillies, cela démontre le rôle essentiel que peuvent jouer des exercices très ciblés, associés à une bonne alimentation, dans la préservation de notre santé osseuse, dans l’espace comme sur Terre ! #εpsilon • @esaspaceflight • @ESA_fr • #WorldOsteoporosisDay

#ICYMI: The booster's for NASA's Artemis III mission are officially stacked! Next up, the SLS core stage will be integrated with the boosters, completing the rocket’s “short stack” configuration that will be used during a future tanking test. Learn more: go.nasa.gov/4BcsSLa
Engineers with NASA’s Exploration Ground Systems complete integration of the aerodynamic nose cones onto the left and right forward segments on the twin SLS (Space Launch System) solid rocket boosters, finishing their stacking operations for Artemis III inside the Vehicle Assembly Building’s High Bay 3 at NASA’s Kennedy Space Center in Florida on Wednesday, Sept. 30, 2026. Each forward assembly contains an aerodynamic top, a forward skirt housing avionics, and frustum housing motors that allow the boosters to separate from the SLS core stage after launch. The twin solid boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis III rocket and provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Pad 39B.

Thanks to the arrival of @SpaceX 35 which is captured here approaching the @Space_Station we now are starting a busy season of science. Some of that science arrived in cooled cargo and will return on dragon when it departs directly to the scientist doing that work. We are grateful to be the on-orbit hands of the scientists that are helping to pave the way to the Moon and Mars.

[🇫🇷 version FR 👇] Apparently, there were auroras on our flight home! The French Air and Space Force crew woke everyone up to see them… everyone except me. I missed the show because I really needed the rest – my amazing flight surgeons made sure I got it! 📸 From the ISS: ESA/NASA – S. Adenot 📸 From the flight home: ESA Apparemment, il y a eu des aurores boréales pendant notre vol de retour ! L’équipage @Armee_de_lair a réveillé tout le monde pour les admirer… ou presque ! Mes médecins de vol ont estimé (et ils ont eu raison !) qu’il était préférable que je dorme, du coup j’ai raté le spectacle... #εpsilon • @esa

Ain’t nothing gonna break my stride (except for maybe gravity!). Here’s a peek into our first @Space_Station post-flight data collection session, immediately after landing in the helicopter after our @SpaceX Dragon splashdown last Thursday. The heel toe walk with eyes open was doable, but definitely off my balance game once they had me repeat with eyes closed (shown here). Exponentially better performance even just the next day, such an interesting recovery process! Stay tuned for the week’s recap of science and rehabilitation.

A look back at the final days of my mission and the journey home! Leaving is never easy, but returning to Earth means carrying home incredible memories, valuable scientific results and profound gratitude for the people who make human spaceflight possible. 🎥 @esa Retour sur les derniers jours de ma mission et le voyage de retour ! Ce n’était pas facile de partir, mais revenir sur Terre, c’est aussi ramener avec soi des souvenirs inoubliables, de précieux résultats scientifiques et beaucoup de gratitude envers toutes celles et ceux qui rendent les vols habités possibles. #εpsilon

Just in time! Some cities seem to enjoy hiding under the clouds ☁️ whenever the Station flies overhead… It took until 6 October, the day before undocking, for me to finally catch Cologne and the European Astronaut Centre (EAC) on camera, with no clouds! I’m currently flying towards that very airport, so to all the @esaspaceflight teams at EAC and the German Aerospace Center (@DLR_SpaceAgency): I can’t wait to see you again! 🫶 📸 @esa / @NASA – S. Adenot Juste à temps! Certaines villes jouent à se cacher sous les nuages ☁️ quand la Station passe au-dessus d’elles… Ce n’est que le 6 octobre, la veille du désamarrage, que j’ai enfin réussi à photographier Cologne et le Centre européen des astronautes (EAC) sans nuages ! Je suis en train de voler en ce moment même vers cet aéroport, alors à toutes les équipes de l’EAC et du Centre aérospatial allemand DLR : j’ai hâte de vous retrouver ! 🫶 #εpsilon • @ESA_fr
