Russian Cosmonaut Pyotr Dubrov to Take Command of the ISS on October 4

Roscosmos cosmonaut Pyotr Dubrov is preparing to assume command of the International Space Station (ISS). The official handover ceremony is scheduled for October 4, 2026, as officially announced by the US space agency NASA. This leadership change in orbit is a critical step in ensuring the continuous operation of the crewed station and maintaining the safety of its international crew.

Preparation for Leadership Change and the Crew-12 Mission

The authority of the current station commander will be transferred to Pyotr Dubrov from NASA astronaut Jessica Meir. This event takes place as part of the scheduled rotation and comprehensive preparations for the return of the Crew-12 long-duration space mission participants to Earth. The departing crew will hand over all operational duties to their colleagues, who will continue orbital research and station maintenance.

The Crew-12 mission crew has been successfully working aboard the International Space Station since mid-February 2026. In addition to Jessica Meir, the team includes Roscosmos cosmonaut Andrey Fedyaev, NASA astronaut Jack Hathaway, and European Space Agency representative Sophie Adenot. During their time in orbit, they completed an extensive program of scientific experiments and technical maintenance.

Duties of the New Commander and Return Schedule

Following the official handover of authority, Pyotr Dubrov will assume full responsibility for coordinating the work of the international crew, maintaining the station's standard operational mode, and efficiently executing the tasks assigned to the ISS commander. The Russian cosmonaut will be responsible for the safety and coordinated actions of all specialists onboard under various operational and contingency situations.

The final return of the Crew Dragon spacecraft carrying the departing Crew-12 crew to Earth is scheduled for October 5, 2026. The astronauts and cosmonauts will leave the International Space Station after completing all necessary undocking procedures, opening a new chapter in the ongoing expedition under the new commander.
