T+267 (5.20.24): One of my favorite games with the EVA training team was asking Drew specific questions about the most obscure EVA equipment to see if I could stump him. I haven't won yet. In return, Jenna and Miranda would bend the pressurized hoses to make the quick disconnects as hard as possible to manipulate. Nothing says we care more than altruistic interference Thank you for the training, team!

Moduł łożyskowo-silnikowy BMRRM (Bearing Motor Roll Ring Module) jest częścią zespołu BGA (Beta Gimbal Assembly) na ISS.
Aby zoptymalizować pozyskiwanie energii, panele słoneczne na ISS muszą być ustawione pod takim kątem, aby wychwycić jak najwięcej fotonów ze Słońca.
Idealnie byłoby, gdyby były one ustawione idealnie prostopadle do słońca, ale nie zawsze jest to możliwe z różnych powodów, takich jak zacienienie.
Ponieważ ISS nieustannie orbituje wokół Ziemi, panele słoneczne są stale obracane, aby utrzymać optymalny kąt.
Można sobie wyobrazić, że gdyby w przesyle danych i energii wykorzystywano kable, to podczas ciągłego obracania się paneli kable te skręcałyby się i plątały, albo BGA musiałby się rozkręcać, aby zapobiec zerwaniu połączeń.

Aby obejść tę trudność, NASA zaprojektowała BMRRM jako moduł typu „wszystko w jednym”.
Łączy on w sobie wsparcie konstrukcyjne dla paneli słonecznych, silnik napędowy umożliwiający ciągły obrót paneli o 360 stopni oraz styki do zasilania i przesyłania danych (bez kabli).

Istnieje komponent zwany podzespołem pierścienia obrotowego (roll ring subassembly), który wykorzystuje elementy toczne i pierścienie przewodzące do stworzenia urządzenia sprzęgającego obrót o 360 stopni, które utrzymuje ciągły kontakt elektryczny, umożliwiając przesyłanie energii elektrycznej i danych w całym zakresie obrotu.

T+269 (5.22.24): This is what I think is the coolest structural component of the ISS, the Bearing Motor Roll Ring Module, or BMRRM (pronounced "broom"). It's part of the Beta Gimbal Assembly (BGA) on the ISS (see figure). Before explaining why I think it's so cool, it's worth taking a step back to understand why it's important.

To optimize energy collection, the solar arrays on the ISS need to be angled to capture as many photons from the sun as possible. Ideally, it would be perfectly perpendicular to the sun, but that's not always possible for various reasons like shadowing. Since the ISS is constantly orbiting the Earth the solar arrays are constantly rotated to maintain an optimal angle. You can imagine if cables were involved in the data and power transfer, the cables would get twisted and tangled as the arrays kept rotating or the gimbal would need to unwind to prevent breaking the connections.

To get around this, NASA designed the BMRRM to be an all-in-one module. It combines structural support for the solar arrays, a drive motor to rotate the arrays 360 degrees continuously, and contacts to supply power and transfer data (without cables). How? There's a component called the roll ring subassembly, which uses rolling elements and conductive rings to create a 360-degree rotational coupling device that maintains continuous electrical contact allowing the transmission of electrical power and data over the entire rotational range. A similar concept applies for the alpha rotary joint. I think it's cool that a coupler can keep rotating and transfer power/data without cables.

NASA współpracuje z każdym międzynarodowym partnerem, aby zapewnić, że wszyscy astronauci na pokładzie będą jednolicie reagować w sytuacjach awaryjnych.
Ta przewidywalność i jednolitość minimalizują ryzyko nieporozumień i zwiększają kompatybilność między partnerami. Tego dnia instruktorzy współpracowali z rosyjską częścią załogi Sojuza MS-27, aby przećwiczyć te umiejętności.

Jonny Kim @JonnyKimUSA 8:44 AM · Mar 25, 2025
T+269 (5.22.24): As a member of the International Space Station, NASA works with each international partner to ensure every astronaut on board will execute an emergency response uniformly. This predictability and uniformity minimize the chances of confusion and increase cross-compatibility across partners. On this day, our instructors worked with my Soyuz crew to practice these skills.

ASCR to trenerzy zajmujący się siłą, kondycją i rehabilitacją astronautów, którzy współpracują z astronautami w celu opracowania programu fitness optymalizującego zdrowie i wydajność.
Ich praca ma kluczowe znaczenie dla powodzenia misji.

Jonny Kim @JonnyKimUSA 8:56 AM · Mar 25, 2025
T+276 (5.29.24): ASCR's are astronaut strength, conditioning, and rehabilitation coaches that work with astronauts to develop a fitness program that optimizes health and performance. Their work is critical for mission success. Bruce is my ASCR and works hard to keep me challenged, correct my form, and give jokes. Thanks Bruce!

Astronauci NASA odwiedzają Tsukubę, miasto w Japonii, które jest zlokalizowane na północ od Tokio, aby zapoznać się z obsługą japońskiego modułu ISS, Kibō.
Dla astronauty była to doskonała okazja na letnie wakacje z rodziną.

Jonny Kimv@ JonnyKimUSA 9:37 AM · Mar 25, 2025
T+292 (6.14.24): The Japan Aerospace Exploration Agency (JAXA) has been an international partner with NASA for decades. As part of the training leading to an ISS mission, NASA astronauts visit Tsukuba, a city in Japan just north of Tokyo, to learn operations within the Japanese ISS module, Kibō. It's a wonderful opportunity to visit a beautiful country and work with our Japanese colleagues. The highlight for me was being able to bring my family along to kickstart our kid's summer vacation from school.

Jedno z badań CIPHER dotyczące adaptacji sensomotorycznej do zmian w warunkach grawitacyjnych.
Badanie rejestrowało zmiany w układzie przedsionkowym za pomocą oprogramowania do śledzenia ruchu gałek ocznych.
Test polegał na kręceniu się na krześle i próbie skupienia wzroku na tym samym punkcie w okularach.
Test ten stanowił punkt wyjścia i będzie powtarzany w trakcie lotu i po locie.

Jonny Kim @JonnyKimUSA 10:44 AM · Mar 25, 2025
T+323 (7.15.24): CIPHER is the name of a large, integrated study that scientists from around the globe are collaborating on to understand how humans adapt to long-duration missions in space. Data is gathered from astronauts pre-flight, in-flight, and post-flight through biological samples, eye and vision exams, cognition and behavioral tests, cardiovascular exercises, ultrasounds, MRIs, and other technologies and techniques.

This was one of the CIPHER studies exploring sensorimotor adaptation to changes in gravity environments. Specifically, examining changes in our vestibular system using eye-tracking software. The test involved spinning in a chair and attempting to focus on the same spot in the vision headset. This test served as a baseline and will be repeated again in-flight and post-flight.

Jonny Kim @JonnyKimUSA 10:35 AM · Mar 26, 2025
T+331 (7.23.24): There's an EVA tool for every imaginable task on orbit, including a caulk-style grease gun for lubricating mechanical components. It doesn't get used too often. The last time was with @lunarloral on US EVA 89 greasing the SARJ trundle bearing assembly (which she did amazingly well without making a mess!). There's also an attachment to get grease in difficult locations.

Lucas does a great job demonstrating how the drive lock assembly on the solar alpha rotary joint works. This is a component that allows the truss containing the solar arrays to rotate.

Piąty EVA w NBL w ramach szkolenia przed misją na ISS to zazwyczaj ostateczna runda ewaluacyjna.
Zespół szkoleniowy i ewaluacyjny musi zapewnić bezpieczeństwo, kompetencje i niezawodność astronautów podczas spacerów kosmicznych.
Zespół stawia bezpieczeństwo na pierwszym miejscu, oceniając jednocześnie pracę zespołową, przestrzeganie procedur i zdolność do odejścia od planu, gdy sytuacja wykracza poza normę.
Jest to standardowy przebieg treningu w NBL z wbudowaną akcją ratunkową.

Jonny Kim @JonnyKimUSA 8:33 AM · Mar 27, 2025
T+337 (7.29.24): The 5th NBL run during a training flow for an ISS mission is usually the final evaluation run, where everything counts. The training and evaluation team must ensure that astronauts are safe, competent, and reliable during a spacewalk. The team prioritizes safety above all, while also assessing teamwork, adherence to procedures, and the ability to deviate from the plan when things go off-nominal.

This run is one of the major milestones in the training flow, and I was privileged to share it with @Astro_Ayers, who is currently in space with Crew-10, and Don Pettit on E72. Other than being an evaluation, it’s a fairly standard NBL run with a rescue scenario baked in. Vapor and I passed, and we have our training teams to thank for it. Thanks, y'all!

Ten test służy NASA jako punkt odniesienia do porównania z wynikami po locie astronauty.

Jonny Kim @JonnyKimUSA 8:53 AM · Mar 27, 2025
T+338 (7.30.24): There are several science refrigerators and freezers on the space station. My favorite is MELFI, which stands for Minus Eighty-degree Laboratory Freezer for the ISS. Technically, it has a set point of -95°C, but I think "MNLFI" would probably be hard to say. Here’s the ground-based version we train on before using the real one in space.

It has four storage cylinders, called dewars, and each dewar contains four trays, which are further subdivided into modules. Science samples are frozen in MELFI to ensure they remain preserved for future study upon return to Earth. Cool, right?

Jonny Kim @JonnyKimUSA 9:10 AM · Mar 27, 2025
T+339 (7.31.24): As part of the CIPHER study, NASA scientists are exploring how changes in gravity affect sensorimotor function to ensure success in future deep space exploration missions. It may seem easy, but tasks as simple as standing, walking, and sitting require extensive coordination across sensory, motor, and cerebellar systems. We take these actions for granted because we don’t have to think about them in our everyday lives. This test serves as a baseline for NASA to compare against my post-flight results. Many thanks to the scientists who work every day to better understand our place in space.

Jonny Kim @JonnyKimUSA 9:58 AM · Mar 27, 2025
T+339 (7.31.24): Another part of the CIPHER study involves understanding ways to mitigate muscle atrophy in microgravity and the impact this has on functional strength. Exercise scientists at NASA use various tools to study this, and this is one of them. It’s called an isometric mid-thigh pull (IMTP), and here’s how it works: you stand on top of a force plate, zero/tare the scale, and then pull as hard as you can against an immovable object—in this case, the barbell, which is strapped down.

The IMTP is well-studied in exercise science because it’s standardized, time-efficient, technique-agnostic, and safer than a 1-rep max. These results will be compared with mid-thigh pulls in space at various times, as well as post-flight after the mission.

The important metric for NASA is not the total force one can generate, but the changes in total force that one can generate across different environmental and gravity factors. A special thanks to Dana Gardner and the Exercise Physiology and Countermeasures Lab at Johnson Space Center.

Jonny Kim @JonnyKimUSA 10:25 AM · Mar 27, 2025
T+339 (7.31.24): One of the things the people behind NASA are really good at is encouraging each other to develop new skills and refine old ones, embracing a very DIY attitude. Prior to NASA, I had an interest in building computers, servers, and creating my own wired network at home. I never thought that crimping RJ-45 plugs onto Cat5e cables would ever come in handy in the future. My point is that developing new skills and adopting a DIY mindset can not only be fun, but it can also surprise you with how much you learn and grow—and how much that can translate to your everyday life.

T+381 (9.11.24): This trip to Star City was for our Sokol suit fit checks, Soyuz qualification exams, and to support Don as his backup. It was a great opportunity to gain cultural insights and learn from veteran astronauts. I really enjoyed spending time with Don during quarantine, and the highlight was watching his rocket roll out and then launch his crew for Expedition 72. Photos courtesy of Roscosmos.

T+389 (9.19.24): Do you do ham radio? I’d never tried it before, but as part of the training flow before an ISS mission, the crew is given an opportunity to earn their amateur radio license. It’s another way for the crew to share education and outreach with amateur radio enthusiasts and organizations like schools while on the space station. Kenneth, our ham radio project coordinator, helped me get certified—thanks, Ken!

In addition to ARED, we have the T2 treadmill and CEVIS stationary bike for cardiovascular fitness. This was one of my last chances to operate the equipment, and Kimberlee ensures astronauts know how to use it before launch.

Jonny Kim @JonnyKimUSA 8:09 AM · Mar 28, 2025
T+394 (9.24.24): We’re trusted with a lot of responsibility. We ensure we respect and care for our equipment so it will care for us when we need it. Part of that respect and accountability involves inspecting our gear, like this 85' safety tether reel that will keep us tethered to the space station in the unlikely event we drift off the ISS during a spacewalk. Lifesaving equipment deserves proper attention and respect, so Drew is ensuring I know how to inspect it correctly.

Another area where astronauts are given autonomy is how we customize our working equipment. Attached is a picture of how I typically customize my mini-workstation—we call it “MWS” for short. The MWS attaches to the chest area of the spacesuit, functioning like a harness to hold tools. Uniformity has its strengths, but so does individual autonomy in operating one’s own gear. Back when I was an operator with Naval Special Warfare, I was given a similar level of trust and autonomy over my equipment customization. As long as teammates follow standardized operating procedures (SOPs), as we do at NASA, individual preferences can coexist with uniformity.

NBL runs 6–9 are less focused on evaluations and more focused on familiarizing the crew with the hardware and procedures they may encounter during the expedition. I had an opportunity to work with Andre Douglas as we familiarized ourselves with the Alpha Magnetic Spectrometer, which may see an upgrade later this year.
