Soyuz MS-04 is a Soyuz spaceflight that launched on 20 April 2017 to the ISS. 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. Originally set to include 3 people, the crew assignments were changed in November 2016 by NASA and Roscosmos.
|Commander|| Alexander Misurkin, RSA|
|Flight Engineer 1|| Nikolai Tikhonov, RSA|
|Flight Engineer 2|| Mark Vande Hei, NASA|
Alexander Misurkin and Mark Vande Hei were reassigned to Soyuz MS-06 and served as part of Expedition 53/54, Nikolai Tikhonov was reassigned to Soyuz MS-10 to serve as part of Expedition 57/58 although was also pulled of that mission due to the same budget cuts, he is now scheduled to be Soyuz Commander of Soyuz MS-14.
