Jour 092, orbite 1425 — L’un des défis du quotidien en micropesanteur : transporter des objets sans les laisser s’échapper !

#εpsilon • @nasajohnson • @iss • @cnes_france

A SpaceX Dragon spacecraft lifted off atop a Falcon 9 rocket at 6:05 p.m. EDT today from Florida with a space delivery for Expedition 74 scheduled at 7 a.m. on Sunday. Watch live on NASA+ beginning at 5:30 a.m.

[🇫🇷 version FR en commentaire] Day 091, orbit 1410 — In this timelapse, I’m first setting up and then carrying out a technology demonstration called Intravenous Fluid Generation – Mini. It explores how the Station’s supply of potable water could be used to produce medical‑grade intravenous fluids, such as saline solutions.
 
Being able to produce IV fluids in space would reduce our reliance on cargo missions and prevent the issue of expired medical supplies during long‑duration exploration missions. One of many examples of the key role the Station plays in inventing the future of space exploration!


The large piece of equipment I’m working in is a sealed laboratory workspace, the Life Science Glovebox, located in the Japanese Kibo module. And if you’re wondering why I’m “tethered” for this experiment… The black one is an antistatic grounding strap. It’s connected to a metal surface and helps keep our body electrically neutral (more on static electricity soon!). The white one is the radio connecting me to POIC Huntsville, who guided me through this experiment.

Congrats Huntsville! Congrats IVGEN teams, especially Alex M., Alex S., Brian, Courtney, John, Kimesha, Moriah, Nathan, Robert, and Toni!

Another of my favorite views from the @iss, the Northern and Southern Patagonian Icefields. I was in awe of the splendor of these glaciers on my first mission, surrounded by mountains, with their tongues melting into pristine turquoise lakes. I vividly recall an iconic view from one of my first spacewalks, as I gazed down at @astro_christina in her spacesuit below me, the lakes appeared just beneath her feet. Of course, viewed over time, the retreat of these majestic bodies of nature tells a sad tale of their demise as our climate changes. Unfortunately, the South American icefields are melting at some of the highest rates on Earth, contributing to rising sea levels.
Photo 1: Note the lines running down the glaciers, marking their active flow.
Photo 2: Zoomed area of the edge of one glacial tongue, you can observe the chunks of ice breaking off and melting away.

Space research is helping beat heart disease. 🫀💫

Pneumonia-causing bacteria can lead to long-term heart damage. Researchers are leveraging the International Space Station to study how heart tissues respond to this bacterial infection in an effort to unlock new methods to manage cardiovascular health and infectious diseases.

In space, bacteria tend to be more severe and have enhanced drug resistance. Scientists are using these traits to exaggerate their effect on heart tissues and reveal important cellular responses that would be difficult to detect on Earth.

Streptococcus pneumoniae, the leading cause of community-acquired pneumonia (CAP), causes millions of deaths yearly. More than a quarter of adults hospitalized for CAP develop heart disease, and survivors of severe cases face long-term risks—even after the infection clears.

This research is also important for expanding our understanding of how the human body and microbes respond to microgravity. The space station remains a vital platform for addressing complex human health issues, both in space and on Earth. 🚀🌍

[🇫🇷 version FR 👇] Day 088, orbit 1365 — A short timelapse of what looks like a very simple task: swapping a hard drive 🔧. Except that it all happens in microgravity, inside the Zero Boil‑Off Tank (ZBOT).

Thanks to POIC Huntsville for the amazing science experiment!

ZBOT is an experimental setup where researchers study how to store propellant more efficiently in space, by using processes that help maintain safe tank pressure while greatly reducing fuel loss.

Sometimes, even the most advanced space research depends on very down‑to‑Earth actions… just performed in a rather extraordinary environment! 😉

Jour 088, orbite 1365 — Un court timelapse d’une tâche très simple à première vue: changer un disque dur 🔧. Sauf que c’est à faire en étant en micropesanteur, et que c’est à l’intérieur du Zero Boil‑Off Tank (ZBOT).

Le ZBOT est un dispositif expérimental dans lequel les chercheurs étudient comment stocker les ergols plus efficacement dans l’espace, grâce à des procédés qui permettent de maintenir une pression appropriée dans les réservoirs tout en réduisant fortement les pertes d’ergols.

Merci au centre de contrôle POIC de Huntsville pour cette super expérience scientifique!

Parfois, même les recherches spatiales les plus avancées reposent sur des gestes très terre‑à‑terre… mais réalisés dans un environnement extraordinaire ! 😉

Happy Mother’s Day to all of the mothers on Earth, from all of the mothers currently in space.

Happy Mother’s Day to all of the mothers on Earth, from all of the mothers currently in space.

[🇫🇷 version FR 👇] Day 085, orbit 1316 — Did you know you can spot the International Space Station using only your eyes? From the ground, it looks like a very bright star moving across the sky at roughly the speed of a commercial airliner. But unlike an aircraft, it has no headlights or flashing navigation lights. Its brightness comes from the solar panels, which are positioned to catch sunlight and reflect it back towards Earth.

To find out when we’ll be passing overhead and where to look in the sky, check out to spotthestation.nasa.gov… I won’t be able to see you, even if you wave very enthusiastically, but I’m thinking of you from up here!

Jour 085, orbite 1316 — Saviez-vous que vous pouvez observer la Station spatiale internationale à l’oeil nu ? Depuis le sol, la Station apparaît comme une étoile très brillante qui traverse le ciel à peu près à la vitesse d’un avion de ligne. Mais contrairement à un avion, elle n’a ni phares, ni feux de position clignotants. Ce sont ses panneaux solaires, orientés pour recevoir la lumière du Soleil, qui la rendent si lumineuse lorsque vous la voyez depuis la Terre.

Pour savoir quand nous passons au-dessus de vos têtes et où nous chercher dans le ciel, rendez-vous sur le site spotthestation.nasa.gov… Je ne pourrai pas vous voir, même si vous faites de grands signes, mais je pense à vous depuis là-haut !

Toward the end of a recent nighttime timelapse from a @spacex Dragon window, I caught this impressive lightning flash. I was astounded by the size and intensity of this monster thundercloud. The things we witness from our vantage point on the @iss never cease to amaze me.

A little love for our OG mom, Earth. 💙🌍 Happy Mother’s Day weekend.

At NASA’s Johnson Space Center, astronauts and teams on the ground work every day to better understand and protect our home planet. From studying Earth’s climate from orbit to advancing technologies that support sustainable exploration, the work happening here helps us care for the world that has always cared for us.

As we head into Mother’s Day weekend, it’s a fitting moment to appreciate the world that has always taken care of us — and celebrate the mothers, caregivers, and communities who do the same.

Thank you to @scripps_ocean and @birchaquarium for providing an extraordinary sea-to-space connection yesterday! We were inspired by the energy in the crowd and were so excited to share our @nasa @iss story. I always appreciate an opportunity to connect with my friends and colleagues at Scripps Institution of Oceanography, where I acquired the skills to be a scientist, explored our planet through remote fieldwork, and discovered the value of solid teamwork and exceptional mentorship (and of course, how to surf!).

The winding Grand Canyon is simply magical viewed from the @iss. Sometimes these images reverse themselves on me, like the old magic eye posters from the ‘90s. Fondly reminiscing about my hiking and exploring adventures at @grandcanyonnps.

Just as my mother always says, nothing beats nature.

You can see the Grand Canyon Village at the top edge of the fourth photo.

The last photo is a less dramatic section of the canyon, but it caught my Earth Art eye.
