Soyuz MS-21 was a RussianSoyuz spaceflight to theInternational Space Station (ISS) with a crew of three launched from Baikonur on 18 March 2022. The launch was previously planned for 30 March 2022, but in the provisional flight manifest prepared byRoscosmos by the end of Summer 2020, the launch of Soyuz MS-21 was advanced to 18 March 2022.[2]
It was the first mission to the ISS with threeRoscosmos cosmonauts.[4]
On 29 September 2022, after 6 months and 11 days, the mission completed successfully as planned with a landing on theKazakh Steppe inKazakhstan.[5]
The three-Russian member crew were named in May 2021.[6] AlthoughNASA had not decided whether or not they would purchase a seat on the flight, NASA astronautLoral O'Hara was preparing to replaceSergey Korsakov if the agency decided to buy a seat.[7] Later, NASA decided not to acquire a seat on the Soyuz MS-21 launching in March 2022, deferring a NASA Roscosmos seat swap forSoyuz MS-22 andSpaceX Crew-5.[8]

The arriving cosmonauts at the station have gained particular international attention after entering in bright yellow suits with blue elements, having changed before and after into different suits.[9] International commentators saw in these colours the national colours ofUkraine and interpreted the personal choice of suits by the cosmonauts as a sign of their sympathy for Ukraine in the light of the parallel ongoing2022 Russian invasion of Ukraine, which strained also space cooperation such as the ISS program afterinternational sanctions on Russia.[10] The cosmonauts said when asked about the colours that the yellow suits needed to be used, and Roscosmos followed with a statement that the colours are to be read as the identifying colours of theBauman Moscow State Technical University, from which all three cosmonauts graduated.[9]
