Soyuz MS-24



The Soyuz MS-24 is a crewed spacecraft. The original three-Russian member crew for this scenario was named in May 2021. American astronaut Loral O'Hara replaced Andrey Fedyaev as a part of the Soyuz-Dragon crew swap system of keeping at least one NASA astronaut and one Roscosmos cosmonaut on each of the crew rotation missions. This allows continuous space station occupation by US and Russia and keep backup crew scenarios to prevent vehicle either vehicle grounding like Soyuz MS-10 launch failure or to compensate for delays in launch of crew rotation missions of either vehicles like SpaceX Crew-3, that was delayed due to unfavorable launch weather conditions.They were originally assigned to Soyuz MS-23 mission, but were moved to MS-24, due to Soyuz MS-22 coolant leak accident that required MS-23 to be launched uncrewed as its replacement. Oleg Kononenko is assigned for an one year long mission with his MS-24 crewmate, Nikolai Chub, that started on September 25, 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.
