Passing the Keys! The Space Station Gets a New Commander Today
Quick Summary
The International Space Station had a special ceremony today, 250 miles above Earth. NASA astronaut Jessica Meir officially handed command of the station to Russian cosmonaut Pyotr Dubrov. Meir and her three crewmates are now packing up to come home after months in space.
What Happened?
A change-of-command ceremony is kind of like a graduation mixed with a going-away party — held in space! At 10:20 this morning, NASA astronaut Jessica Meir officially transferred leadership of the ISS to Roscosmos cosmonaut Pyotr Dubrov. The ceremony was streamed live so people on Earth could watch.
Meir arrived at the station back in February 2026. She has been the commander, which means she was responsible for the safety of the entire crew and the station itself. That is a huge job. The ISS is as big as an American football field, travels at 17,500 miles per hour, and currently has people from the United States, Russia, and Europe all living and working there together.
Meir’s crew — which includes NASA pilot Jack Hathaway, ESA astronaut Sophie Adenot from France, and Russian cosmonaut Andrey Fedyaev — is now preparing to climb back into their SpaceX Dragon spacecraft. They plan to undock on October 7 and splash down in the Pacific Ocean off the coast of California on October 8.
Waiting aboard the station to take over is a fresh crew, including cosmonaut Pyotr Dubrov, who will now lead the expedition. The station stays busy with science experiments on everything from how the human body changes in space to how plants grow without gravity.
Why Does It Matter?
The ISS is one of the greatest team projects in human history. Sixteen countries worked together to build it, and it has been home to astronauts from around the world for more than 25 years without stopping. Change-of-command ceremonies make sure there is always an experienced leader at the station, keeping everyone safe and the science moving forward.
Big Words
- Commander — the leader of a mission, responsible for making sure everyone is safe and the work gets done
- Cosmonaut — the Russian word for an astronaut; both words mean someone who travels to space
- Expedition — a planned journey or mission, especially one to explore or do science in a challenging place
- Undock — to disconnect a spacecraft from the space station so it can fly away on its own
- Splashdown — when a spacecraft lands in the ocean by parachuting down and floating
Fun Fact
SpaceX Dragon capsules can travel from the launch pad to the International Space Station in as few as eight hours — faster than a flight from New York to Australia!

If you were in charge of the International Space Station for a day, what one experiment would you want to run up there — and why?
