Crew
editThey were originally assigned to Soyuz MS-23, but they were moved to MS-24 due to a coolant leak on Soyuz MS-22 that required MS-23 to be launched uncrewed as its replacement and returned to Earth uncrewed. Oleg Kononenko was assigned for a one year long mission with his MS-24 crewmate Nikolai Chub that started on September 15, 2023. As the mission lasted 374 days, Kononenko spent a total of 1,111 days in space. He exceeded the previous record of 878 days held by Gennady Padalka on 4 February 2024. He later became the first person to stay 900, 1,000, and 1,110 days in space on 25 February 2024, 4 June 2024, and 12 September 2024 respectively.

Undocking and Return
editAt the end of Expedition 70, O'Hara returned to Earth on Soyuz MS-24 with Roscosmos cosmonaut Oleg Novitsky and Belarusian spaceflight participant Marina Vasilevskaya (both on ISS EP-21) on 6 April 2024. On the other hand, Kononenko and Chub remained onboard the ISS for a year and returned to Earth with NASA astronaut Tracy Caldwell-Dyson on Soyuz MS-25. As the mission lasted 374 days, Kononenko spent a total of 1,111 days in space by the time he returned to Earth. He broke the world record of 878 days in space held by Gennady Padalka on February 4, 2024 at 07:30:08 UTC. He later became the first person to stay 900, 1,000, and 1,100 days in space on 25 February 2024, 4 June 2024, and 12 September 2024 respectively.[4]
