Minął ponad tydzień od startu.
Wspomnienia astronauty towarzyszące rozpoczęciu misji.

Jonny Kim @JonnyKimUSA 1:48 AM · Apr 17, 2025
It’s been just over a week since our launch. As I reflect, these are the core memories that will stay with me from that unforgettable day:

Watching the suit engineers meticulously check each connection and seal—something I deeply appreciated.
Seeing my friends and family during walkout. My children, smiling behind the glass, playing rock-paper-scissors with me as we waited for the pressure check. Waving our final goodbyes.
Walking up to our rocket and realizing—it’s a living, breathing giant. The gravity of the moment didn’t fully hit me until I saw frosty snowflakes drifting off the supercooled rocket and heard the groans of metal expanding and contracting.
Thinking of my family as I listened to our launch playlist while waiting on the launchpad. Then listening to the engines roar to life, feeling the G-forces slowly building in our chests, and being impressed by how familiar it all felt—the launch, ascent, and orbital insertion—like another sim or centrifuge run. A true testament to the depth and excellence of the training we received.
And then there it was, the International Space Station. A shining cathedral of metal, floating just beyond our window on final approach.
Reuniting with our friends from MS-26 and Crew-10 after hatch opening was a moment of pure joy.

Life aboard the ISS has been busy adjusting to the new environment and learning how to contribute to the mission. This national laboratory above our planet is alive with science, discovery, and purpose, and I’m excited to share it with you over the next eight months.

Pierwsze strzyżenie na orbicie.

Jonny Kim @JonnyKimUSA 12:51 AM · Apr 18, 2025
M+5: First hair cut in space, @Astro_Ayers is a pro! Thank you! ISS is where we work, but it’s also where we eat, sleep, recover and work out. And one of the things we routinely do is cut our hair, which can present unique challenges in space. If the hair if not collected it will float and clog up our air filters so we connect a vacuum hose to clippers to collect the hair as it’s cut.

Jonny Kim @JonnyKimUSA 8:23 PM · Apr 18, 2025
M+8: The ISS has multiple airlocks, some are designed for astronauts and equipment, and others like this one, the JEM airlock from the Japan Aerospace Exploration Agency, are designed not for humans but for small payloads. This particular airlock is positioned next to a Japanese platform for payloads that sits outside the ISS. We can use this airlock to take stuff inside to space, or from space to inside.
@Astro_Onishi  and I worked together to assemble the sliding table so that we can deliver science payloads to the outside of the @Space_Station. Then we double checked the airlock interior to ensure we didn’t leave any tools or equipment inside which could get unintentionally lost in space.

3) Pomaganie w zakładaniu plecaków SAFER.
Jest to plecak odrzutowy z 24 maleńkimi silnikami napędzanymi sprężonym azotem, który pozwala na poruszanie się z pewną swobodą.
Jego zastosowanie możliwe jest tylko w sytuacjach awaryjnych, gdy spacerowicz oddali się od ISS za bardzo i straci z nią więź.

Jonny Kim @JonnyKimUSA 6:03 PM · Apr 19, 2025
My crewmates @AstroAnnimal and @Astro_Ayers are set to head out on a spacewalk in early May to upgrade one of our solar arrays. There’s a ton of prep involved before they go out the hatch.

@Astro_Onishi and I will be their suit IVs — basically, we help them get in and out of their suits, walk them through prebreathe protocols (so they don’t get decompression sickness sometimes called the ‘bends’), and handle all sorts of other behind-the-scenes stuff.

One of the cooler things we get to do is help them don their SAFERs — the closest thing to a jetpack that an astronaut can wear. It’s hard to describe, but it’s kind of like a backpack with 24 tiny thrusters powered by compressed nitrogen that let you move in some degrees of freedom. It’s only used in emergencies, if someone ever gets untethered and drifts away from the station.

We’ve practiced with SAFERs on Earth, but this is my first time handling one in space. Tak and I have been rehearsing how to get them on and off the same suits Anne and Vapor will be using. It’s great to see all this training come to life up here.

M+10: In prep for the upcoming spacewalk, @Astro_Onishi and I helped @AstroAnnimal and @Astro_Ayers suit up in their real suits today for final checks to ensure proper fit and function. Anne made a great time lapse of the process. We also held our Change of Command ceremony aboard the ISS: a proud tradition marking the formal handover of authority and leadership. Expedition 72 Commander Alexei Ovchinin passed the ISS keys to Expedition 73 Commander Takuya Onishi. Excited for the science and spacewalks ahead, but sad to say goodbye to friends from Soyuz MS-26. Wishing @astro_Pettit a happy birthday and a joyful reunion with his family back on Earth.

Przybycie Cargo Dragon CRS-32.

Jonny Kim @JonnyKimUSA 7:54 PM · Apr 25, 2025
M+14: Our first resupply mission for Expedition 73. Tak and I were the visiting vehicle officers for @NASA’s CRS-32 mission, meaning we monitored the rendezvous, approach and docking from the Cupola as the @SpaceX Cargo Dragon autonomously docked to the International @Space_Station carrying science, equipment, and resources like food.

We can’t do our job as astronauts without regular resupply missions like this, and the success of CRS-32 is a testament to NASA’s partnership and collaboration with the commercial industry.

While our job was not to take pictures, during the approach we had a short window of opportunity to snap some photos of Dragon as it maneuvered in a semicircular fashion from underneath (nadir) the ISS to in front of us where it gets obscured by the Japanese Experimental Module and finally maneuvers above us as it docks to the zenith port of the Node 2 module.

Unfortunately I caught some light artifacts around Dragon, which I think could be minimized if I had grabbed a camera shroud. Welcome to any suggestions from experts.

Jonny Kim @JonnyKimUSA 6:24 PM · Apr 28, 2025
M+14: So what happens after a cargo resupply vehicle docks to the @Space_Station?
Same thing when a supply ship reaches its destination on Earth.

The cargo needs to be unloaded and stowed away. We call this “Cargo Ops” and if able, it’s an all-hands on deck operation to get as much precious cargo containing food, science experiments, equipment, etc. to its final destination.

Our Lab module gets very busy since it’s the central highway connecting all of our USOS modules, but in microgravity we can use the ceilings or walls to get by so it’s not too bad squeezing past people with cargo bags.

M+16: If you’ve lived on MREs, you’ve probably tried some creative field recipes.

Here is a twist on the ranger burger, one of my favorites: beef steak, wheat snack bread, cheese spread as both topping and glue, potatoes au gratin layered in the middle, and a generous slather of gochujang red pepper paste from a care package on the SpX-32 Cargo Dragon.

I miss cooking for my family, but this hits the spot in its own way.

M+22: Tomorrow, @AstroAnnimal and @Astro_Ayers will be performing a spacewalk on the outside of the @Space_Station to set up a solar array upgrade and move an antenna in preparation for Japan’s future HTV-X spacecraft.

Today is a more relaxed day, giving us time to inventory all of our equipment and study our roles. Tak and I will be the suit IVs, meaning it is our responsibility to ensure that Anne and Vapor are properly suited up and pass all safety checks.

Their lives are in our hands, so we’ll be triple checking each other and methodically going through our procedures and checklists.

Once we button them up, it’s up to Anne, Vapor and the Houston ground team to execute the mission. Tak and I will be ready to receive them in the airlock when they are complete.

Kim i Ayers byli odpowiedzialni za dopilnowanie, aby spacerowicze przestrzegali protokołów dotyczących wstępnego oddychania (pre-breathe) , aby zminimalizować ryzyko choroby dekompresyjnej, a ich skafandry były idealnie założone.
W tym celu dokonano czterokrotnego sprawdzenia każdej kamery i zamka, aby zagwarantować sprawne wykonaniu spaceru.

Jonny Kim @JonnyKimUSA 6:14 PM · May 2, 2025
M+23: Amazing EVA yesterday! Huge congratulations to the EVA and flight control teams, @AstroAnnimal, @Astro_Ayers, our instructors, and Tak, who led the IV support with exceptional skill.

Tak and I were responsible for ensuring Anne and Vapor adhered to pre-breathe protocols to minimize decompression sickness risks and that their suits were perfectly donned. We must have quadruple-checked every cam and lock to guarantee our friends faced no suit issues during their EVA.

EVA day powerfully illustrates the trust we place in each other’s hands—our lives depend on it. A special thanks to Tak and Anne for teaching this rookie some invaluable IV tricks.

My favorite? Tak’s clever technique for helping Vapor out of her suit. On Earth, gravity does the work, but up here on the @Space_Station, we need some new tricks.

Astronauci z powrotem w śluzie powietrznej po wykonaniu spaceru.

Jonny Kim @JonnyKimUSA 5:41 AM · May 3, 2025
M+23: An EVA (spacewalk) is a long day for all involved—flight control and EVA teams, spacewalkers, and IV teams.

NASA TV captures the 6.5–7-hour EVA, but not the extensive same-day preparations or the hours of post-mission cleanup.

This is a time-lapse of @Astro_Onishi and me welcoming spacewalkers @AstroAnnimal and @Astro_Ayers back to the airlock after their successful mission.

We assist them in removing their spacesuits and organize the airlock. In the coming days, Anne and Vapor will undertake critical tasks to prepare their suits and the airlock for future spacewalks, ensuring readiness for upcoming missions.

Similarly, ground teams will conduct post-mission analysis and debriefings, sharing lessons learned to enhance future operations.

M+23: Last Thursday, a portion of @AstroAnnimal and @Astro_Ayers's spacewalk targeted the port solar arrays, which the windows of the Japanese Experiment Module had a great view of.

During orbital night, the International @Space_Station is enveloped in complete darkness—Vapor’s helmet lights were the only reason I could spot her.

Though she might appear alone in the abyss of space, Vapor is supported by her partner, Anne, while ground control teams provide guidance each step of the way.

Daytime photos reveal the immense scale of the arrays compared to the astronauts. It was awesome to see them thrive in their element.

Jonny Kim @JonnyKimUSA 8:50 PM · May 7, 2025
M+20: Life is busy up here aboard the @Space_Station.

A typical day might involve anything from transferring water tanks, photographing colleagues conducting experiments or assembling glove boxes so we can perform scientific research.

We also ultrasound ourselves frequently for various research studies or in this case, to examine the vessels behind the knee (specifically the popliteal vein) to determine if there are any issues with blood flow that could cause problems down the line.

O badaniach ultrasonograficznych.

Jonny Kim @JonnyKimUSA 5:35 PM · May 12, 2025
M+28: One of our frequent activities aboard the @Space_Station is performing ultrasounds. Ultrasound is a highly effective diagnostic tool—real-time, user-friendly, radiation-free, and capable of providing valuable data for health and research purposes.

Best of all, it doesn’t require sticky ultrasound gel. In space, water’s surface tension dominates, causing it to “stick” to any surface it touches. Since water is an excellent medium for ultrasound, this makes conducting scans much easier in space than Earth.

Here, @Astro_Onishi assists me, guided remotely by Houston watching via video downlink, in capturing ultrasound images of my eye. Monitoring eye health is critical, as spaceflight can sometimes cause adaptive changes to the eye’s structure.

Another essential task is toilet maintenance, in this case a filter replacement. The toilet is a vital piece of equipment on the space station, so we take its maintenance very seriously.

O różnicach między stanem mikrograwitacji a ziemskim środowiskiem przy wykonywaniu nawet prostych zadań.

Jonny Kim @JonnyKimUSA 6:56 PM · May 14, 2025
M+29: Many habits that work on Earth don’t work in microgravity. I’ve been surprised by how differently I must approach tasks, even simple ones such as transferring items between bags to carrying objects.

Here’s an example: on Earth, we walk with our legs and carry things with our hands. In microgravity, we ‘walk’ (we call it translate) with our hands, freeing up our legs.

So, it’s often more practical to carry items with our legs and move with our hands—the opposite of Earth. Just one of many differences in life aboard the @Space_Station

Eksperymenty z różnymi rodzaju nanomateriałami.

Jonny Kim @JonnyKimUSA 5:07 PM · May 16, 2025
M+30: One of the experiments we’re conducting on the International @Space_Station is to see how different types of nanomaterials can be fabricated in microgravity to improve biomedical applications on Earth.

@Astro_Ayers and I worked together in the Life Sciences Glovebox, guided by the research team to conduct their experiment.

The experience brought back nostalgic memories of working on a summer bench research project at the Broad Institute during medical school under Drs. Matthew Meyerson and Ami Bhatt.

Science experiments are the lifeblood of our Space Station and we look forward to conducting more research on our Expedition.

Eksperyment botaniczny Air Force Academy w celu zbadania czy zastąpienie dwutlenku węgla może zmniejszyć zależność rośliny od fotosyntezy i przyspieszyć wzrost roślin uprawianych w kosmosie.

Jonny Kim @JonnyKimUSA 6:09 PM · May 19, 2025
M+33: The Air Force Academy (@Astro_Ayers's alma mater) is doing a neat botanical experiment to examine whether a carbon dioxide replacement can reduce a plant’s dependence on photosynthesis and increase growth in space-grown plants.
This can help reduce energy use on future missions and help us understand how plants adapt to life in microgravity. It’s been fun watching these little guys sprout!
