Behind the Scenes: How Astronauts Continue Their Mission Amid the U.S. Government Shutdown on the International Space Station (Sept. 29 – Oct. 3, 2025)

The Expedition 73 crew is busy with research and maintenance aboard the International Space Station (ISS), even as a U.S. government shutdown unfolds on Earth. This dedicated team continues to push the boundaries of science in microgravity.

Japanese astronaut Kimiya Yui shared a glimpse of life in space on social media. “Today was packed, but I managed to snap some photos during my workouts,” he posted. He mentioned how they flew over Japan after capturing images near the Mediterranean Sea, creating a connection with those waving from below. Astronauts often share real-time experiences like this, fostering a unique relationship with Earth’s inhabitants.

Research is a key focus for Expedition 73. Among their projects, Jonny Kim, a NASA astronaut, worked with the State-of-the-art Humidity Removal in Microgravity Payload. This device captures moisture from the station’s atmosphere to recycle it, which is essential for long missions. Mike Fincke, another NASA astronaut, looked into heat transfer processes, studying how gases become liquids, which could help engineers design better thermal systems for deep-space travel. Lastly, Zena Cardman installed new samples for the ADvanced Space Experiment Processor-4, a project aimed at manufacturing medicines in microgravity, further showcasing how space research contributes to healthcare advancements on Earth.

On top of their research, the crew also maintains the ISS’s systems, a vital aspect of keeping the station functional. Fincke and Kim worked on the Fluid Science Laboratory, an important tool from the European Space Agency (ESA) that helps researchers understand fluid dynamics in space. They made adjustments to electrical cables and set up samples for future experiments.

Fincke also took on the installation of the TransAstra Fly Trap Capture Bag Demo. This innovative technology is being tested to capture and potentially dispose of space debris, a growing concern in today’s crowded orbit. Space debris can pose a serious threat to both existing satellites and the ISS itself.

Another essential task involved the Electrostatic Levitation Furnace, where Kimiya Yui focused on configuring hardware. This device is designed to heat materials to extremely high temperatures using lasers, providing critical data on material properties which can be invaluable for future engineering solutions.

As of October 3rd, the ISS hosts seven crew members: Expedition 73 commander Sergey Ryzhikov and fellow cosmonauts, along with astronauts from NASA and JAXA. Two crew spacecraft—SpaceX’s Dragon “Endeavour” and Roscosmos’ Soyuz MS-27—are currently docked, alongside four cargo spacecraft. This marks an impressive continuous crew presence in space for nearly 25 years.

This ongoing research and collaboration illustrate how human presence in space is not just about exploration; it’s about advancing technology and improving life on Earth.
