Aurora watching into an orbital dawn. This never gets old!

Expedition 74, how was your @SpaceX Dragon delivery? This time-lapse video shows Dragon approaching the International Space Station above the Indian Ocean, crossing the Himalayas into China, and then docking over the Pacific Ocean as the sun sets on May 17, 2026.

NASA’s SpaceX Crew13 astronauts – Jessica Watkins, Luke Delaney, and Joshua Kutryk – recently visited Kennedy Space Center, getting a hands-on look at how today’s work supports tomorrow’s exploration. 🌱🚀

Inside the Space Systems Processing Facility, the crew and NASA astronaut Stan Love sampled fresh microgreens, part of ongoing research into fast-growing, nutrient-rich crops that could help sustain astronauts during long-duration missions. These small plants pack a big punch, and learning to grow them efficiently is key as crews start traveling farther from Earth.

The astronauts also toured the Vehicle Assembly Building, where they viewed major Artemis III and Artemis IV hardware – another reminder that today’s Commercial Crew missions help prepare humanity for our return to the Moon and future deep space journeys.

I’ve spent much of the last 3 days since the @spacex cargo vehicle arrived in another of my happy places on the @iss, the “LSG” or Life Sciences Glovebox, doing cell biology experiments. Extremely rewarding for a biologist turned astronaut like me!

On Monday I thawed frozen platelets and bone-marrow megakaryocytes (cells that are integral to the formation of blood clots and the immune response), supplied them with fresh media (the nutrients they need to live and grow), and injected them into a biocell habitat (photo 1).

Tuesday I exchanged the media for another experiment, this time to feed neocartilage (engineered cartilage tissue grown in a lab for surgical implantation) (photo 2). Some of these samples include tension mechanisms, which have shown to improve neocartilage properties. Interestingly, the mechanism of pure tension cannot be studied on Earth because of the constant presence of gravity.

Today (Wednesday), I exchanged the media for the cells in Monday’s experiment. @astro_hathaway assisted by shepherding cells and supplies from their incubators to the glovebox (photos 3 and 4).

Fingers crossed that all of the cells are happy and thriving and can thus provide a better understanding of inflammatory and clotting conditions in both microgravity and back on Earth!

[🇫🇷 version FR 👇] Day 096, orbit 1489 — So happy and honoured to have been monitoring the @spacex CRS-34 cargo Dragon approach and docking on Sunday, 17 May, together with @astro_hathaway! It always feels a bit surreal to see another spacecraft catching up with us, flying in formation with the Station for a while and then slowly closing the distance… at the orbital speed of 28000km/h!

Next: about 3 tonnes of equipment to unload, including a lot of time critical science, and also supplies & food…

Jour 096, orbite 1489 – Très heureuse et honorée d’avoir surveillé l’approche et l’amarrage du cargo Dragon CRS-34 de @spacex ce dimanche 17 mai, avec @astro_hathaway ! Cela paraît toujours presque irréel de voir un autre engin spatial nous rejoindre, voler en formation avec la Station, puis se rapprocher tout en douceur… à la vitesse orbitale de 28000 km/h !

Au programme : près de 3 tonnes à décharger, dont de nombreuses expériences scientifiques qui ne peuvent pas attendre, des provisions et des fournitures…

The @SpaceX Dragon delivered a host of space experiments on May 17, 2026, the crew is now working on. Some of the new studies will take advantage of weightlessness to develop advanced treatments for Earth ailments and space-caused conditions.

Dragon, with its nose cone open to reveal its docking mechanism, approaches the International Space Station carrying nearly 6,500 pounds of food, supplies, and equipment for the Expedition 74 crew. This mission marked SpaceX’s 34th commercial resupply services flight to the space station for NASA.

Things are getting spicy up here on the @iss with the arrival of the @spacex 34 Dragon cargo vehicle this weekend, bringing us supplies (yes, even some ice-cream!), care packages, and most importantly, a bounty of novel scientific experiments that are keeping us very busy and stimulated! Stay tuned for news on that front, but here’s a look at her just before and after docking, taken from our @spacex Dragon window.

Cheers to Jessica Meir: 300 days in space and a legacy that keeps lifting future explorers. 🎉

NASA astronaut Jessica Meir has officially reached 300 cumulative days in space, adding to a career defined by scientific discovery and history‑making achievements. Meir first lived aboard the International Space Station as a flight engineer for Expeditions 61 and 62, where she supported human physiology research and contributed to a wide range of science investigations conducted in microgravity .

From supporting human physiology research to taking part in the first all‑female spacewalks, Meir’s time in orbit continues to advance @NASA’s goals for long‑duration exploration. Now serving on Expeditions 74/75, she’s helping drive the science and operations shaping future missions beyond low Earth orbit.

Reaching 300 days underscores Meir’s ongoing contributions to NASA’s mission — from advancing human health research to helping shape the next era of exploration carried out by teams at Johnson Space Center.

[🇫🇷 version FR 👇] Day 095, orbit 1474 — This large piece of equipment is the Life Science Glovebox, located in the Japanese Kibo module. It is a sealed laboratory workspace in which we can safely handle biological samples that require a high level of containment. A contaminated atmosphere is one of the main risks we face aboard the Station, but it’s just as important to make sure we don’t contaminate the research!
 
In this picture, I’m processing blood stem‑cell samples, helping scientists better understand how we could produce larger quantities of clinical‑grade stem cells in space. This biotechnology research aims to improve stem-cell quality, with potential benefits for the treatment of blood diseases and cancer. It may also open up new opportunities for commercial research in orbit. Space research, playing its part in advancing science. Go science!

Congrats to the teams, especially Blake, Brandon, Chen, Jim, Maddie, Max, Pinar, Raquel,Tan, Trystin and Yupeng!

Jour 095, orbite 1474 – Cette grande boite à gants est le Life Science Glovebox, situé dans le module japonais Kibo. Il s’agit d’un espace de laboratoire fermé dans lequel nous pouvons manipuler en toute sécurité des échantillons biologiques nécessitant un haut niveau de confinement. Nous cherchons évidemment à éviter de respirer une atmosphère contaminée, mais il est tout aussi important de veiller à ne pas contaminer les expériences !

Sur cette image, je manipule des échantillons de cellules souches sanguines, afin d’aider les scientifiques à mieux comprendre comment produire de plus grandes quantités de cellules souches de qualité clinique dans l’espace. Cette recherche en biotechnologie vise à améliorer la qualité des cellules souches, avec des retombées potentielles pour le traitement des maladies du sang et du cancer. Elle pourrait également ouvrir de nouvelles perspectives pour la recherche commerciale en orbite. La recherche spatiale contribue à repousser les limites et à faire progresser nos connaissances… Vive la science !

Have you ever kicked a soccer ball and wondered why it curves, spins, or sometimes wobbles? NASA astronaut Jessica Meir aboard the International Space Station explains the science hidden inside every ball. Engineers carefully design soccer balls so they fly smoothly whether they’re being kicked in your backyard or in the World Cup.
