Matveev, Artemyev and Korsakov 

Soyuz MS-21 is a Russian Soyuz spaceflight to the International 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 by Roscosmos 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 three Roscosmos cosmonauts.


The three-Russian member crew were named in May 2021.[4] Although NASA had not decided whether or not they would purchase a seat on the flight, NASA astronaut Loral O'Hara was preparing to replace Sergey Korsakov if the agency decided to buy a seat.[5] Later NASA decided not to acquire a seat on the Soyuz MS-21 launching in March 2022, deferring a NASA Roscosmos seat swap for Soyuz MS-22 and SpaceX Crew-5.[6]

Arrival suits

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.[7] International commentators saw in these colours the national colours of Ukraine and interpreted the personal choice of suits by the cosmonauts as a sign of their sympathy for Ukraine in the light of the parallel ongoing 2022 Russian invasion of Ukraine, which strained also space cooperation such as the ISS program after international sanctions on Russia.[8] 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 the Bauman Moscow State Technical University, which all three cosmonauts graduated from.[7]
