We deploy the Canadarm for a lot of different tasks such as inspection of vehicles before an undock. It’s nice to see a friendly neighborhood spider arm.

M+10: In prep for the upcoming spacewalk, 大西卓哉（JAXA宇宙飛行士）Takuya Onishi and I helped COL Anne McClain and Nichole “Vapor” 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 Don Pettit a happy birthday and a joyful reunion with his family back on Earth.

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. 大西卓哉（JAXA宇宙飛行士）Takuya Onishi and I worked together to assemble the sliding table so that we can deliver science payloads to the outside of the International 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.

My first time-lapse. Thanks to some instruction and tips from Nichole “Vapor” Ayers, I caught my first aurora. After seeing the result, I told her this felt like fishing. Prepping the camera, the angle, the settings, the mount, then setting your timer and coming back to hope you got a catch. And after catching my first fish, I think I’m hooked. Thanks, Vapor! Beautiful auroras passing over southeastern Asia and Australia.

Another time lapse of the solar particle event last month. I accidentally captured parts of the window frame but I think it adds to the ISS feel. Nikon Z9 | 14mm | Nov 12, 2025.

In advance of the NG-23 cygnus capture with the Canadarm, Houston gave our crew onboard an opportunity to practice moving the arm and capturing a simulated grapple fixture (i.e. target). This is a timelapse over 2 hours capturing Houston maneuvering the Canadarm for this practice.

On Nov 13th, there was a solar particle event that resulted in beautiful blankets of aurora. You may have seen it. We had the most amazing view and our crew collectively took thousands of photos and dozens of time lapses. Here is one of those time lapses. Nov 13th. Nikon Z9 | 14mm.

In space, we’re weightless, but not massless. So how do we measure our mass? There are a few ways to do it, but they all come down to Newton’s Second Law: F = ma. Apply a known force, measure the resulting acceleration, and you can calculate mass from the relationship between the two.

Caught a fish! Hope you enjoy this round of space fishing for beautiful auroras. If you’re wondering what the reflections in the lower left are, I made a rookie mistake of not having the shroud completely cover the window so you can see some crew activity (the cupola is located adjacent to one of our exercise devices).

There is a science lab onboard the International Space Station called the Life Sciences Glovebox. It’s one of the places we conduct biological and life science experiments in a controlled environment. It can control temperature, humidity, and even has a negative pressure environment so we can work with hazardous materials. Recent experiments in the LSG include a study to determine how bone cells can respond to various conditions in microgravity and determining if higher fidelity protein crystallization in space can yield more effective drugs. Here’s a short video describing what it is and how we deploy it.

M+38: One of the experiments we’re conducting on the International Space Station is to expand on current hardware, demonstrating the creation of golden nanospheres under microgravity conditions, which are larger and more uniform than their Earth-bound versions, and have applications in cancer diagnostics and treatment and improved pharmaceuticals. We obtain our samples from the MELFI freezer and grow them into our Industrial Crystallization Cassettes, and will package them for return on Spx-32 for additional analysis.

Earlier in this mission, Spx-33 did a checkout of its reboost capability. In preparation for that maneuver, the solar arrays on the International Space Station had to park in a safe position. Here’s a time lapse demonstrating the solar arrays autotracking the position of the sun then feathering to a safe position. Notice in this sped-up video how the solar arrays can rotate about two different axes, one controlled by the SARJ (solar alpha rotary joint) and the other by the BGA (beta gimbal assembly). This allows fine tuning the position of the arrays to optimize sunlight conversion to electricity.
