(Manned missions)

Soyuz MS-04 is a Soyuz spaceflight that launched on 20 April 2017 to the ISS.[1] It transported two members of the Expedition 52 crew to the International Space Station. MS-04 is the 133rd flight of a Soyuz spacecraft. The crew consists of a Russian commander and an American flight engineer. It is the first of the Soyuz MS series to rendezvous with the Station in approximately 6 hours, instead of the 2 day orbital rendezvous used for the previous launches. It was also the first Soyuz to launch with only 2 crew members since Soyuz TMA-2.

Due to a decision to cut down the number of participating Russian astronauts in 2017, only two astronauts have been launched on Soyuz MS-04.[4] Originally set to include 3 people, the crew assignments were changed in November 2016 by NASA and Roscosmos. Of the original crew, Alexander Misurkin and Mark T. Vande Hei have been assigned to Soyuz MS-06 instead.[5]
