[🇫🇷 version FR 👇] Space missions definitely put every system in the human body to the test! 😅 During the εpsilon mission, I took part in Exposome Signature, a study looking at how astronauts adapt to the combined stresses of spaceflight. Interestingly, the study also follows submariners. Like us, they experience isolation, confinement and demanding operational conditions, but without microgravity or cosmic radiation. Comparing the two groups helps researchers distinguish which changes may be specific to spaceflight. 🧬 The study looks at a wide range of factors, including markers of inflammation, immune function, metabolism, the microbiome and gene activity. It continues long after splashdown to track how our bodies readapt to life on Earth. 🌍 What we learn could help us prepare for future human exploration missions, while also improving our understanding of the effects of prolonged stress and isolation on the human body. Go science! 🔬 📸 @esa – M. Cowan Les missions spatiales mettent à rude épreuve tous les systèmes du corps ! 😅 Pendant εpsilon, j’ai participé à Exposome Signature, une étude qui cherche à comprendre de quelle manière les astronautes s’adaptent aux différents facteurs de stress liés aux vols spatiaux. Fait intéressant, l’étude suit également des sous-mariniers, qui sont tout comme nous confrontés à l’isolement, au confinement et à des conditions opérationnelles exigeantes, mais sans micropesanteur ni rayonnement cosmique. Les chercheurs comparent les données des deux groupes pour essayer de déterminer quels changements pourraient être spécifiques aux vols spatiaux. 🧬 L’étude s’intéresse à de nombreux aspects: marqueurs de l’inflammation, fonctionnement du système immunitaire, métabolisme, microbiome et activité des gènes. Et elle se poursuit bien après l’amerrissage, afin de suivre la manière dont nos organismes se réadaptent à la vie sur Terre. 🌍 Les éclairages apportés par cette étude pourraient nous aider à préparer les futures missions d’exploration habitée, et améliorer notre compréhension des effets du stress prolongé et de l’isolement sur le corps humain. Allez la science ! 🔬 #εpsilon • @esaspaceflight • @ESA_fr

From microgravity 🛰️ to anti-gravity! Back at the European Astronaut Center, post-flight reconditioning included running on the anti-gravity treadmill, which, despite its name, does not actually eliminate gravity… 😁 The lower body is enclosed in an air-pressure chamber. By adjusting the pressure, the treadmill reduces the load on the legs, muscles and joints, allowing you to walk or run while bearing less than your normal body weight. That was fun, but I was so happy to be actually running outside a few days after! 🏃‍♀️‍➡️🌴 📸 @esa – M. Cowan De la micropesanteur 🛰️ à l’antigravité ! Quand j’étais au Centre européen des astronautes pour la période post-vol, j’ai eu droit à des séances sur un tapis de course très spécial, appelé “antigravity treadmill”. Contrairement à ce que son nom laisse penser, il ne fait pas vraiment disparaître la gravité… 😁 Le bas du corps est placé dans une chambre pressurisée, et il suffit d’ajuster la pression pour réduire la charge sur les jambes, les muscles et les articulations, permettant ainsi de marcher ou de courir en ne supportant qu’une partie de son poids habituel. Bon, c’était sympa, mais c’était encore + sympa de courir dehors quelques jours après ! 🏃‍♀️‍➡️🌲 #εpsilon • @esaspaceflight • @ESA_fr

The space station isn't just a laboratory for space science. It's helping researchers explore new ways to benefit patients on Earth and astronauts on future deep-space missions. Learn about ISS National Lab-sponsored research in this area: ow.ly/bgFI50ZZ3Kv

実は、宇宙飛行士になってから一番恐れおののいていた訓練が、自分で自分の血を採る「自己採血」。 宇宙飛行士は自分で採血しなければならない時もあるらしい、ということは以前から何となく知っていました。でも、私は昔から採血が大の苦手。採血されるときは必ず顔をそむけていたくらいです。 宇宙飛行士になってからは、この日のために、まず健康診断で採血されるときに「針を見る」ところから始め、少しずつ心理的な準備を重ねてきました。 前回の訓練では、うまく血管に針が入らず失敗。でも、気を取り直して臨んだ今日は、ついに成功! さらに、練習台を買って出てくださったジョンソン宇宙センターのスタッフの方からの採血も、一発で成功しました! 実は、宇宙飛行士の採血の練習台になりたいというボランティアの方はジョンソン宇宙センターには結構多いそうです。 勇気ある皆さんに、最敬礼です!🙇‍♂️ #宇宙飛行士 #宇宙飛行士訓練 #JAXA #ISS

Astronauts like @soph_astro and submariners may have more in common than you think. 🧑‍🚀⚓ By studying both, Exposome Signature is helping scientists understand how our bodies respond to extreme environments, with benefits for health in space and on Earth. 🔗 esa.int/Science_Exploration/… #εpsilon

I was seated in the audience front row, and recognised Heide's symptoms. The crew, behind her, couldn't see that she was about to faint, so I jumped onto the stage and luckily caught her in time. Ever since then, astronauts sit during the debriefs immediately post-spaceflight. Don't need anyone falling and getting hurt.
On September 22, 2006, NASA astronaut Heidemarie Stefanyshyn-Piper collapsed twice at a welcome-home ceremony in Houston. Officials attributed her wobbles to her body readjusting to Earth's gravity after 12 days in space.

This week in space science we have been incredibly busy. ADSEP is just one example of the research that flew up on SpaceX-35. This one is pharmaceutical development in a box to take advantage of microgravity for drug production!

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!

Yesterday’s bone density scans. This DEXA (Dual-Energy X-ray Absorptiometry) machine uses low dose X-rays to measure bone density and body composition. Without the loading signal of gravity, our bones will leach calcium in space, which can lead to significant losses in bone density. This is why it is so important for us to exercise in space. Thanks to lots of weight lifting on the @Space_Station, the preliminary results show that the bone density in my spine actually increased in space!
