Soyuz MS-24, Russian production No. 755 and identified byNASA asSoyuz 70S, was a Russian crewedSoyuz spaceflight launched fromBaikonur on 15 September 2023 to theInternational Space Station.[1]
The crew was originally assigned toSoyuz MS-23, but they were moved to MS-24 due to a coolant leak onSoyuz 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 crewmateNikolai 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 byGennady Padalka on 4 February 2024. 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.

On the other hand, Kononenko and Chub remained onboard the orbital laboratory for a year and returned to Earth withNASA astronautTracy Caldwell-Dyson onSoyuz 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 byGennady 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]
