The symbolic handoff of the keys to the International Space Station
When astronauts rotate command of the orbital laboratory, it is more than a bureaucratic shift. It is a ritual of continuity. From symbolic keys to unexpected early returns, the changing of the guard on the ISS marks the delicate balance of human life in low Earth orbit.
The transition of power aboard the International Space Station is marked by a formal change-of-command ceremony, where the outgoing commander passes a symbolic key to their successor. In April 2025, this ritual saw Roscosmos cosmonaut Alexey Ovchinin hand control of the station to JAXA astronaut Takuya Onishi. During the ceremony, Ovchinin emphasized the weight of the responsibility, telling Onishi, "Take care of our station. It's our everything."
These ceremonies often coincide with the departure of entire crews. For instance, the end of Expedition 72 involved the undocking of Ovchinin, Ivan Vagner, and Don Pettit aboard a Russian Soyuz spacecraft on April 19, 2025. Their journey was slated to conclude with a touchdown in the Kazakhstan steppe on April 20. Such transitions are highly choreographed, signaling the start of a new era, such as the transition from Expedition 72 to Expedition 73 under Onishi's command.
However, orbital rotations are not always predictable. In January, NASA announced an accelerated return for the SpaceX Crew-11 mission. This decision, made on January 8, was driven by the need to monitor a medical concern involving a crew member. While the individual was reported to be stable, the agency maintained medical privacy regarding the specific nature of the issue. This unexpected shift meant that Mike Fincke was set to hand command of Expedition 74 to Sergey Kud-Sverchkov under different circumstances than originally intended.
