Soyuz MS-23 was a Roscosmos Soyuz MS spacecraft, MS No. 754, launched without a crew from Baikonur Site 31/6 on February 24, 2023 UTC. It was sent to the International Space Station as the replacement return craft for Sergei Prokopyev, Dmitri Petelin, and Frank Rubio after the Soyuz MS-22 coolant leak. The spacecraft docked to the station's Poisk module, later relocated to Prichal, and returned the three MS-22 crew members to Kazakhstan on September 27, 2023 after their extended 371-day station mission.
