Soyuz MS-24 was a Russian crewed Soyuz spaceflight launched from Baikonur on 15 September 2023 to the International Space Station.[1]
They were originally assigned to Soyuz MS-23 mission, 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. Oleg Kononenko is assigned for a one year long mission with his MS-24 crewmate Nikolai Chub that started on September 15, 2023. If the mission lasts 300-365 days, Kononenko will have spent a total of 1,036-1,101 days in space, exceeding the current record of 878 days by Gennady Padalka. He will thus also become the first person to stay 1,000 days in space.

After completing her expedition, Loral returned to Earth on 6 April 2024 with Roscosmos cosmonaut Oleg Novitsky and Belarusian spaceflight participant Marina Vasilevskaya (both on ISS EP-21) on the Soyuz MS-24 spacecraft. On the other hand, Kononenko and Chub will remain aboard the ISS orbital laboratory for about one year and return with NASA astronaut Tracy Caldwell-Dyson on the Soyuz MS-25 spacecraft. If the mission lasts 300–365 days, Kononenko will have spent a total of 1,036–1,101 days in space, exceeding the current record of 878 days by Gennady Padalka. He will thus also become the first person to stay 1,000 days in space.[4]
