The mission transported two new crew members of ISS Expeditions 51 und 52 to the International Space Station. This crew was originally scheduled to travel with the Soyuz MS-05; however, Roscomos decided to bring the mission forward and remove one crew member, Paolo Nespoli, so as to cut down the number of participating astronauts and make savings on the operation of the ISS. Additional cargo was transported to the ISS in Nespoli’s place and labelled with the name “Paolo”.

On board ISS
On 12th May, Peggy Whitson and Jack Fischer replaced an electronic unit and a protective shield as part of an EVA (extravehicular activity) assignment.
On 20th May, an important technical device failed. Since this could have led to huge operational restrictions on the ISS, Whitson and Fischer were required to carry out unscheduled EVA.
Undocking & landing
According to plan, Soyuz MS-04 docked to the Russian ISS module Poisk in “express mode” – that is, in six hours instead of in two days.
The Soyuz MS-04 spacecraft lands with Expedition 52 Commander Fyodor Yurchikhin of Roscosmos and Flight Engineers Peggy Whitson and Jack Fischer of NASA near the town of Zhezkazgan, Kazakhstan on Sunday, Sept. 3, 2017 (Kazakh time). Whitson is returning after 288 days in space where she served as a member of the Expedition 50, 51 and 52 crews. Yurchikhin and Fischer are returning after 136 days in space where they served as members of the Expedition 51 and 52 crews onboard the International Space Station.
The Werenbach crowdfunding project began on 1st April 2017, and the funding target was achieved within an hour. After just half an hour, we realised that the huge demand for Model 5 would require us to urgently secure the supply of new material. To this end, Patrick Hohmann took a spontaneous trip to Kazakhstan on 1st May, managing to procure material from the outer cladding of the rocket engine and the fairing.
