Descriptions:

• Soyuz MS-21 is a Russian Soyuz spaceflight to the International Space Station (ISS) with a crew of three planned for launch 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.
• The three-Russian member crew were named in May 2021. Although NASA had not decided whether or not they will 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 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. It will be the first mission to the ISS with three Roscosmos cosmonauts.
  Soyuz MS-21 is the 148th? crewed flight of a Soyuz spacecraft.

Mission details:

• ISS Expedition 66.
• Manned ship "S. P. Korolev” (Soyuz MS-21) with the crew of the 67th long-term expedition to the International Space Station at 22:12:06 Moscow time docked to the node module “Prichal” of the Russian segment of the ISS. This was the first docking of the ship to the new Russian module. The rendezvous was carried out according to a two-orbit scheme under the control of specialists from the Main Operational Group for Controlling the Russian Segment of the ISS (Rocket and Space Corporation Energia named after S.P. Korolev, part of the State Corporation Roscosmos). Now the crew is preparing to perform operations to open transfer hatches: checking the tightness of the ship's compartments, switching to combined power, equalizing pressure between the ship and the station, as well as removing and drying the Sokol KV-2 flight suits. Upon completion of the leak test of the joint between the spacecraft and the Prichal node module, it is planned to open the hatches at 00:20 Moscow time on March 19. After that, a newly arrived crew consisting of three Roscosmos cosmonauts - Oleg Artemiev, Denis Matveev and Sergey Korsakov - will go to the ISS. The live broadcast of this operation will be available from 23:50 Moscow time.
