To anyone who doesn't know who Jonny Kim is and where he came from you need to watch this.
It's quite long, like over 4 and a half hours so you might need to pause and restart a few times but watch it.
Very inspiring guy.

Astronaut Takuya Onishi's aspirations

I have been appointed as the ISS Commander during the 73rd Expedition. I would like to take this opportunity to thank everyone who has worked hard to make this decision, as well as those who have provided guidance and support.

I'm not the type of leader who stands at the front of the team and leads the team, but rather I think of myself as the type of leader who allows the team members to move freely and supports the whole team as the unsung hero. I want to do my job to the best of my ability, using my own style.
And we will do our best to make this mission a fulfilling one not only for our long-term stay crew, but also for all the people who support our stay on the ground. Thank you for your continued support.

T+24 (9.20.23): We use different mediums and modalities to aid our study and preparation for a mission. A pretty cool one is our use of VR. We have the entire international space station and its components mapped in a VR environment. Couple this with physical hardware on a system of pulleys and levers to mimic the same mass handling qualities you'd find on orbit and we get a pretty cool "feel" of what it's like to move stuff around on orbit. This can be particularly helpful in building our sense of how a payload will feel in space translating with it or installing it.

T+29 (9.25.23): Who do you call when the toilet breaks?

In space, you are the plumber.

That's why @NASA_Astronauts are trained to repair and maintain all vital equipment on the @Space_Station. And the toilet, officially called the Waste and Hygiene Compartment (WHC), is pretty vital on board the space station. It's a vacuum-based system that is comprised of pumps, fans, valves and special chemicals to safely process urine in a multi-step process that converts it to potable water. Thanks to our excellent systems instructors, we're well prepared. Thanks Ryan!

The ISS-73 crew had a test training in the disciplines “Spacesuit for EVA” and “System of Airlock Facilities”
| Crews
January 28, 2025

Sergei Ryzhikov and Alexey Zubritsky performed a series of operations that cosmonauts perform in orbit on the Russian segment of the ISS in preparation for spacewalks, while working outside the station and when returning back. Such training takes a full day on the ISS RS and Exit-2 simulators.

In real space flight conditions, preparation for extravehicular activity (EVA) begins approximately two weeks before the scheduled date of spacewalk.
On the day of EVA in orbit, the crew checks systems and performs preparatory work in accordance with onboard instructions and transmitted radiograms.

After the cosmonauts have prepared the station before going into outer space, in real flight conditions they move to MIM2, and during training - to the Exit-2 simulator, which includes modules of the main and reserve airlock compartment with equipment in a mock-up design , which allows you to work out all the necessary operations.

During the test training on the Exit-2 simulator, Sergei Ryzhikov and Alexey Zubritsky demonstrated the skills they acquired during training in performing forward and reverse airlocks in Orlan spacesuits. If the process is proceeding normally, then the operators check the spacesuits, and then the compartment for leaks, and isolate it from the rest of the station using a hatch.

Next, the astronauts undergo a desaturation procedure to prepare the body for work in a spacesuit. Operators then release the pressure in the MIM2 compartment to be able to open the access hatch. After another check of the compartment for leaks, the astronauts receive permission to go into outer space.

But at every stage of this work, the crew was introduced to emergency situations. During the test training, Sergei Ryzhikov and Alexey Zubritsky worked out actions to eliminate leaks in spacesuits during exit, failure of the main fans of the spacesuits, and leaks in the exit hatch during reverse airlocking.

The ISS-73 crew successfully dealt with all emergency situations that arose during the spacewalk and received permission to perform extravehicular activities in real space flight conditions.

Then the cosmonauts returned to the ISS RS simulator, where they completed operations to bring the “station” to its original state after the spacewalk.

Now Sergei Ryzhikov and Alexey Zubritsky are undergoing training as the main crew of the 73rd long-term expedition to the ISS.

T+36 (10.2.23): This particular day was oxygen appreciation day. We take a lot of things for granted on our planet, and one of those is the recycling of the air we breathe. There aren't enough plants in the ISS at any given time to convert the carbon dioxide (CO2) humans produce back into oxygen. We rely on machines to do that. But if anything happens to those machines and the sensors that detect CO2, we must be able to recognize when CO2 levels get high. CO2 in high enough concentrations is poisonous to our bodies. High levels of CO2 in our blood is called hypercapnia, and can be fatal if not addressed.

That is one reason we learn to recognize our symptoms to dangerous levels of CO2. To perform the test, we breathe into a closed system while closely monitoring our vitals like heart rate, oxygen blood saturation, breathing rate, and logging symptoms we feel. For me, I tend to get headaches and feel my face get hot and flushed at moderate CO2 levels, and when my CO2 levels get really high I get tingling sensations in my fingers  (called paresthesias). It is an uncomfortable test, but it can be life-saving to know one's symptoms. Just a note, never try this test without professionals. This is only done under safe and professional circumstances.

T+38 (10.4.23): There are basically two ways for a space vehicle to get connected to the space station. One of them is called docking, and that's when the space vehicle manually or automatically docks directly to an available port on the space station (examples are the SpaceX Dragon and Soyuz vehicles). The other way is called berthing, and that is when the vehicle holds a position near the space station and operators manually pilot a robotic arm (on ISS it's the Canada Arm) to capture the spacecraft and maneuver it to the attachment site.

On this particular day, I got to work with the legendary Tux to brush off my robotic piloting skills to capture spacecraft in our simulator. This particular simulator is pretty cool, it is dome-shaped and feels very immersive. In addition to piloting the robotic arm, we must be able to recognize unsafe situations and respond to off-nominal situations to keep everyone safe. It's days like these I get to tell my mom that all those video games eventually came in handy! Shoutout to Tux for his years of service in making safe robotic operators!

T+39 (10.5.23): If you like tools, you'll love the EVA hardware at NASA. Our engineers have devised tools to accommodate almost every conceivable use case. The key word is "almost," because we still find edge cases where a tool does not yet exist to fit a particular function (e.g., new tools were created relatively recently for repairing and upgrading the alpha-magnetic spectrometer). Luckily, we have fantastic engineers who constantly build and iterate.

This day was all about reviewing EVA tools that a spacewalker might encounter on an EVA (spacewalk). There are too many to cover, but I'll summarize the bread-and-butter tools.

All tools need a solid foundation to rest on, and that's where the mini-workstation, called MWS for short, comes in. It connects to the suit around the chest area and has multiple tether points to tether tools to, as well as connection points to connect swing arms and our trusty body restraint tether (BRT). Think of it as a tool harness and tool belt in one.

Next is the BRT, which is connected to the MWS and has large jaws at the end that can connect to various things like handrails. This tool is designed in a ball stack fashion that remains flexible when loosened but rigidized when tightened, allowing spacewalkers to stay connected while hands-free. The most common use of the BRT is to attach large objects so spacewalkers can translate without having to hold onto the object or to connect spacewalkers to the station and rigidize so the astro remains in a static position in their worksite. You can imagine if you need both hands to manipulate tools at your worksite, but one hand is tied up holding on to the space station, a BRT acts like a 3rd arm.

Next is the safety tether, arguably one of the most important pieces of gear we use. The safety tether is our lifeline, if for whatever reason we become detached from station, the safety tether will reel us back to its attachment point, which is usually near the airlock.

One cool NASA design that is hard to appreciate in the picture, is that our safety hooks require intentional hand manipulation to actuate. The large hook in my hand will not open unless it is 1) unlocked 2) paddles are squeezed and 3) the trigger is depressed. If any of the above 3 are not met, the hook will not open. This makes accidental actuation of lifesaving equipment much harder. This multi-step process to actuate life-saving equipment is a common theme in our design inventory.

Next is our articulating portable foot restraint (APFR), which you'll find connected to the space station at various places. If you ever see an astronaut in a static "standing" position connected to station with both hands-free, it's because they are in this APFR. Think of it like a standing plate that you snap your boots into to lock in place.

Last is pictured our payload retention device, basically a large tie-down ratchet strap. Not something that is commonly used, but I find it cool nonetheless because of how overbuilt it is.

Last but not least, is our pistol grip tool (PGT), my favorite. Whenever we need to tighten or loosen bolts, we use a PGT. Its got a programmable function to set specific torque levels. There's a mini display that counts the number of turns, and shows set torque and running torque values.

Bonus - this is our EVA toolbox that permanently lives outside of the space station. It has various tool boards and carriers to house various equipment. It has a pretty cool function for the panels to slide out and rotate. The toolbox isn't used often from what I understand, but it's always there and has contingency tools in case spacewalkers need them.

Thanks to EVA instructor, Bridget Scheib for her encyclopedic knowledge of EVA tools!

@JonnyKimUSA
T+40 (10.6.23): Hatch seals and locking mechanisms are important in a space environment. This day was a nice review of how to operate hatches and troubleshoot.

A lot of the food on the space station is created in the food lab at NASA Johnson Space Center with fresh ingredients, then freeze-dried into packages for our consumption. In the video, you'll see how straightforward it is to reconstitute our food. First connect your food to the potable water dispenser, select the volume of water, and push the "hot" dispense button for hot or ambient button for room temperature water.

Lastly, we went over the internal thermal control system (ITCS) on ISS. A lot of heat is generated by system racks and payloads inside the ISS. The ITCS system shunts heats loads away from the racks to the interface heat exchanger connected to the external thermal control system (ETCS) which then dissipates those heat loads to radiators outside the space station. But sometimes leaks happen, and when they do, astronauts are trained to be astro plumbers and help find leaks and bypass them with jumper hoses if necessary.

T+44 (10.10.23): Newton's third law of motion states for every action, there is an equal and opposite reaction. How is this relevant for a spacewalk? Well, per Newton if I try to drive a bolt clockwise into the space station, if I am not properly braced to counteract the force, I will start to spin counter-clockwise as part of the opposite reaction.

On Earth, we don't give much thought to our body position when operating tools like a power drill/driver or a torque wrench. After all, gravity is more than enough to plant our bodies to the ground and counteract typical forces we would impart into tools. But in space, it's important we understand the torque directions our bodies will have to react against in microgravity. So before imparting any loads into the station, our instructors train us to think of the direction of force we are imparting and how to safely react against it.

And while we have pretty unique tools on the station, you'll find many common terrestrial tools on the station as well, like these wrenches in my hand, being used to remove docking equipment from a hatch.

T+47 (10.13.23): Did you know that astronauts can "run" in microgravity? We have a beast of a treadmill we call "T2," also known officially as the Combined Operational Load Bearing External Resistance Treadmill, or COLBERT (named after Stephen Colbert who won a NASA naming contest years ago). In addition to giving some normalcy to astronauts living in the space station, it is a great tool for cardiovascular and bone health.

But before we can use it on the station, we have to learn to use the terrestrial version. To keep us attached to the treadmill on station, we outfit ourselves with a harness attached to the T2 by bungees.

You can imagine the repetitive forces of running on a treadmill would impart a lot of loads into station that could induce unwanted mechanical stress into vital components of station, or impart forces into science experiments that require a microgravity environment (basically one of the biggest reasons we have a space station is to conduct microgravity experiments). So NASA engineers devised a clever way to minimize the forces imparted to station through a device called the vibration isolation system, or "VIS" for short. The design is based on multiple stages of springs oriented in all 3 axes of a Cartesian coordinate system (x, y, z axis) that work together to isolate the forces from a runner on the treadmill.  Watch longtime NASA engineer and instructor, Bob Tweedy, show us how one of the four corners of the VIS works.

One thing I imagine I'll miss once I'm on board station is taking hot showers after a run. The space version of showers involves no rinse shampoo and wet towels, but field showers are better than no shower!

How to prevent biodegradation? Cosmonaut Alexey Zubritsky is preparing to conduct a scientific experiment
| Crews
February 10, 2025

In any room on Earth, a person has microscopic “neighbors”: bacteria and fungi. They are distinguished by their unpretentiousness in choosing food sources, high survival rate, and the ability to adapt to different environmental conditions, including extreme ones. Microorganisms also exhibit purposeful behavior aimed at ensuring the survival and reproduction of the species.

Therefore, a variety of bacteria and microscopic fungi are present in spacecraft and at orbital stations. Conditions in outer space influence the phenotype and genotype of these life forms, and it is not always possible to make a reliable prediction regarding the behavior of even harmless species of microorganisms and their reactions to a new environment. Many of them are potentially dangerous, as they can cause damage to the materials from which the structures are made.

To monitor the composition of microorganisms and their impact on structural materials on the ISS RS, the space experiment “Biodegradation” is being conducted. Alexey Zubritsky, who is now preparing for a space flight as part of the 73rd long-term expedition, had a practical lesson in preparing for this experiment.

Sampling from various internal surfaces of the ISS RS, their preservation and delivery to Earth is carried out using a special “Biosample” package. On the Russian segment of the station, 26 sampling points have been identified, which are located in various zones of possible accumulation and development of destructive microorganisms. The places where sampling takes place remain unchanged, which makes it possible to trace the dynamics of their microbial colonization.

The procedure is carried out one day before the last cleaning of the station before undocking the descent module. During the experiment, the cosmonauts perform photographic recording of all surface sampling sites. The collected material is delivered to Earth for subsequent study of the species composition of biodestructors and microbiological analysis at the Faculty of Biology of Moscow State University named after M.V. Lomonosov.

During the research at the station, experts identified 77 types of microorganisms: 51 types of molds, 2 yeasts and 24 types of bacteria.  The experiment showed that the population of the ISS RS by microorganisms changed in waves, but overall remains low.

Representatives of the 10 most typical species of fungi that can cause biodamage are stored in the All-Russian collection of microorganisms, and the five most common species of technophilic bacteria have been added to the All-Russian collection of industrial microorganisms.  In addition, the five most aggressive technophilic fungal cultures are patented.

Based on the research carried out and the collection of cultures compiled, methods are being developed to prevent the appearance of microorganisms, suppress their growth and vital activity in microgravity conditions in order to ensure the biological safety of the structures of spacecraft and orbital stations.

NASA, SpaceX Update Crew-10 Launch, Crew-9 Return Dates

Elyna Niles-Carnes Posted on February 11, 2025

NASA and SpaceX are accelerating the target launch and return dates for the upcoming crew rotation missions to and from the International Space Station. The agency’s Crew-10 launch now is targeting Wednesday, March 12, pending mission readiness and completion of the agency’s certification of flight readiness process. The Crew-9 mission is planned for return to Earth following a several day handover period with the newly arrived Crew-10 expedition crew.

The earlier launch opportunity is available following a decision by mission management to adjust the agency’s original plan to fly a new Dragon spacecraft for the Crew-10 mission that requires additional processing time. The flight now will use a previously flown Dragon, called Endurance, and joint teams are working to complete assessments of the spacecraft’s previously flown hardware to ensure it meets the agency’s Commercial Crew Program safety and certification requirements. Teams will work to complete Dragon’s refurbishment and ready the spacecraft for flight, which includes trunk stack, propellant load, and transportation to SpaceX’s hangar at 39A at NASA’s Kennedy Space Center in Florida to be mated with the mission’s Falcon 9 rocket. This will be the fourth mission to the station for this Dragon, which previously supported the agency’s Crew-3, Crew-5, and Crew-7 flights.

“Human spaceflight is full of unexpected challenges. Our operational flexibility is enabled by the tremendous partnership between NASA and SpaceX and the agility SpaceX continues to demonstrate to safely meet the agency’s emerging needs,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We greatly benefit from SpaceX’s commercial efforts and their proactive approach in having another spacecraft ready for us to assess and use in support of Crew-10.”

The change also will allow SpaceX, which owns and operates the Dragon fleet, to complete the new spacecraft’s interior build and perform final integration activities, while simultaneously launching Crew-10 and returning Crew-9 sooner.

The Crew-10 mission will carry NASA astronauts Anne McClain, commander; and Nichole Ayers, pilot; JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, mission specialist; and Roscosmos cosmonaut Kirill Peskov, mission specialist, to the space station.

After Crew-10 arrives to the space station, Crew-9 will help the newly arrived crew familiarize with ongoing science and station maintenance work, which supports a safer transition of operations aboard the orbital complex. Following the handover, NASA and SpaceX will prepare to return to Earth NASA astronauts Nick Hague, Suni Williams, and Butch Wilmore, along with Roscosmos cosmonaut Aleksandr Gorbunov aboard Crew-9 pending weather conditions at the splashdown sites off the coast of Florida.
