Trening z używania dużych narzędzi wykorzystywanych podczas EVA.

Jonny Kim @JonnyKimUSA 3:57 PM · Mar 11, 2025
T+137 (1.11.24): This is Drew and he is part of my awesome EVA task training team (including Miranda and Jenna) familiarizing me with various large EVA tools. There are a lot of tools, some are multifunctional and some have single, specific jobs. Some are also very intense looking.  It's hard to appreciate, but the task board has pressurized lines to mimic the rigidity that an astronaut might encounter on orbit. These rigid, pressurized lines are very difficult to manipulate on the ground, so I can only imagine how hard they are on orbit. Technique >> brute strength for successful mating of these lines.

Moduł kontrolera ręcznego HCM (hand controller module) plecaka SAFER ma dwa tryby, z których każdy steruje 4 z 6 stopni swobody DOF (degrees of freedom).

Jonny Kim @JonnyKimUSA 8:14 AM · Mar 17, 2025
T+138 (1.12.24): As mentioned before, the SAFER can be used to pilot an astronaut in an emergency back to the ISS in the highly unlikely event they become untethered from station (would require independent mechanical and procedural errors so really unlikely). I find the handling controls to achieve this fascinating. The hand controller module (HCM) has two modes, with each mode controlling 4 of the 6 degrees of freedom (DOF). What are the 6 DOFs? It's a representation of movement through 3d space by either moving linearly (X, Y, Z) or rotating axially (Pitch, Yaw, Roll). If you play a first person video game, you are controlling 5 of the 6 DOFs without probably even thinking about it (WASD keys do the X,Y,Z translations while the mouse controls pitch/yaw).

One HCM mode is for translational control, moving in the X, Y and Z planes plus pitch (in other words, straight forward, backward, right, left, up and down). The other mode is for rotational control, allowing motion for pitch, yaw, roll plus X. There's also a button, auto attitude hold (AAH) that is super important. What it does is nullify all rotational motion. Remember Newton's 1st law (an object at rest remains at rest and an object in motion remains in motion at a constant velocity unless acted on by an external force)? Say I'm accidentally removed from station, and I am spinning with an initial rotational velocity in all 3 axes (pitch/yaw/roll), then I need to introduce an acceleration in the opposite directions to stop spinning. The AAH button allows the SAFER to understand its rotational velocity and introduce the thrust in the opposite direction to stop that motion. In our VR piloting exercises, we setup an artificial situation where we get forcefully removed from station, at which point we have to enable the HCM and pilot back to the ISS. Our flight paths are captured to show how efficient and accurate we were. There is only enough compressed gas for one shot - if you miss, it's not good.

Attached pictures show the flight path of a "good" flight path and a "mediocre" one where I completed the objective, but took a bit of a sportier path. The technique to save yourself is all based in vector math, which I'll explain in a later post.

Druga długa podróż do Star City i trening przetrwania.
https://x.com/JonnyKimUSA/status/1901550052415242303

Jonny Kim @JonnyKimUSA 9:23 AM · Mar 17, 2025
T+141-173 (1.15-2.16.24): Second major trip in Star City, learning to work in the Soyuz as a flight engineer. One of the highlights of the trip was getting to work closely with my NASA backup and building relationships with our Russian colleagues. We particularly enjoyed our winter survival training, learning from our instructors how to survive off the land in a harsh environment until help arrives should the need arise.

I'd be remiss if I didn't mention one of the highlights of the training was discovering my love for Tvorog, which is a component of the Russian food survival kit, basically a Russian version of the MRE. Never had it before, hard to describe, but so delicious.

Praca zespołowa powiązana z dokładnym przestrzeganiem procedur.

Jonny Kim @JonnyKimUSA 9:48 AM · Mar 17, 2025
T+183 (2.26.24): No "i" in team. So much of what we do is support each other. Which is why we train so much in helping each other suit up before an EVA. When we say we put our lives in each other's hands, we mean it. That means being meticulous with each connection, following checklists, and backing each other up.

Trening w używaniu  ARED Advanced Resistive Exercise Device (ARED).

Jonny Kim @JonnyKimUSA 11:09 AM · Mar 17, 2025
T+192 (3.6.24): Strength training is required for astronauts to fight bone loss and muscle atrophy in space. Leading up to a spaceflight, we have a dedicated astronaut strength, conditioning & rehabilitation coach (ASCR) to teach us how to use our on-orbit resistive device, ARED, and ensure we're following an optimized strength routine. Most of the exercises are compound movements, though we also do isolation exercises too. The squat is probably the most common and famous compound exercise on Earth, as it is on orbit.

Did you know that ARED uses two vacuum cylinders with pistons as the source of constant resistance? This constant resistive load can be changed from 50-600 pounds by adjusting the length of the lever arm. If you're having trouble imagining the source of resistance, pretend you have a small syringe, then push the plunger and cover the opening tip with your finger. If you pull back on the plunger, you will feel resistance because of the vacuum you created. Now attach that plunger to a complex series of lever arms and you have ARED. This is a major simplification of clever engineering but it captures the main concept.

POGO (partial gravity simulator) pomaga docenić astronautom znaczenie pozycji ciała i przeciwdziałających sił podczas spaceru kosmicznego.

Jonny Kim @JonnyKimUSA 11:51 AM · Mar 17, 2025
T+197 (3.11.24): This contraption is called POGO (partial gravity simulator) and helps us appreciate the importance of body position and countering forces during a spacewalk. In a previous post, I talked about the importance of Newton's 3rd law and this is our practical way of understanding how that affects us. As you can see, takes a village of instructors and engineers to train astronauts for flight.

Jonny Kim @JonnyKimUSA 7:58 AM · Mar 23, 2025
T+205 (3.19.24): Ultrasound is an excellent tool with benefits in human health research, diagnostics, and even space station maintenance. Astronauts work in real-time with experts on the ground to guide ultrasound examinations. In my previous life, I used ultrasound to assist with medical procedures and gain valuable real-time patient information. Now, I'm getting reacquainted with a probe to help NASA with medical research on how spaceflight affects change in the human body. Other uses for ultrasound include air leak detection.

Jonny Kim @JonnyKimUSA 8:20 AM · Mar 23, 2025
T+207 (3.21.24): Instructors ensure astronauts have familiarity with the equipment they're likely to encounter on a mission. This day was focused on cameras and freezers.

MELFI is a freezer astronauts use to store science samples for return. There is a window called WORF (Windows Observational Research Facility) on the nadir side of the US LAB facing toward Earth. A clever design allows the window shutter to be actuated from the front of the rack.

Trening z obsługi Canadarm2.

Jonny Kim @JonnyKimUSA Mar 23
T+211 (3.25.24): One of the fascinating properties of the Canadarm2 is the platform-agnostic approach to vehicle berthing operations. In other words, the arm can capture any type of space vehicle (or payload) because the attachment mechanism is the same. Space vehicles can connect to the ISS by either docking directly to the space station or berthing, which means it maintains a static distance from the space station while a robotic arm is piloted to attach to the vehicle then bring the vehicle to a docking port. The training environment in the video illustrates what it looks like to pilot a robotic arm to capture a vehicle. Shout out to the amazing robotics team headed by Tux.

Pomiar tempa metabolizmu.

Jonny Kim @JonnyKimUSA 10:59 AM · Mar 23, 2025
T+212 (3.26.24): NASA exercise and nutrition physiologists are invested in ensuring optimized health and performance of astronauts for long-duration missions. In addition to tracking the macronutrients astronauts consume during a mission, physiologists calculate our resting metabolic rates by having us breathe in a closed environment connected to a metabolic analyzer that measures oxygen consumption (VO₂) and carbon dioxide production (VCO₂).

Another VO₂ measurement we do is the VO₂ max test, which measures the highest amount of oxygen our body can use during intense exercise (we use a stationary bike), which is an indicator of cardiovascular fitness. The VO₂ max test is repeated on-orbit throughout a long-duration mission to compare with our baseline.

Trening z EMU w SSATA (Space Station Airlock Test Article) z obniżeniem ciśnienia do próżni.

Jonny Kim @JonnyKimUSA 11:40 AM · Mar 23, 2025
T+213 (3.27.24): Before a launch, astronauts get an opportunity to get in a class-I EMU spacesuit and depress to vacuum in a pressure chamber called SSATA (Space Station Airlock Test Article). SSATA is a human-rated, high fidelity, 1-G Airlock facility located in Johnson Space Center that provides flight-like simulation of Airlock and EVA operations in pressures ranging from vacuum to 1 atmosphere. This was Don's turn and as his backup, I worked with the team to support his suit-donning and airlock depressurization. Depressurizing to vacuum is a big deal and a lot of people at NASA work behind the scenes to make it safe.

T+248 (5.1.24): The NBL control center is a room above the pool where our EVA task instructors lead us through NBL training runs. If you're ever visiting Johnson Space Center it's a great educational field trip. As mentioned in a previous post, there has been some experimenting with training in the dark to mimic a night pass during a spacewalk. Here, Jenna, one of my task instructors walks us through our 4th NBL run in the series and you can see the contrast between lights on and off in the pool.

T+253 (5.6.24): Building strong bonds through shared challenge and vulnerability is a foundational principle of teamwork. The National Outdoor Leadership School (NOLS) has a history of collaborating with NASA to tailor expeditions to build on good expeditionary behaviors. We spent a week in the beautiful Pacific Northwest to build on these skills. Thank you, Katie and Ben!
