Soyuz MS-04 Construction, Testing and Integration

In the first manned launch of 2017, the Soyuz MS-04 spacecraft was slated to carry two members of Expedition 51 and 52 to the International Space Station, ISS. Roskosmos made a decision to reduce the Russian crew aboard the ISS beginning in 2017 to save funds. After a technical delay, a liftoff of Soyuz MS-04 was re-scheduled for April 20, 2017. The spacecraft is expected to remain docked at ISS until Sept. 3, 2017. As of 2014, the Soyuz MS-04 mission was planned for March 30, 2017, but the launch was later advanced to March 27, 2017, during the adjustment of the overall ISS flight manifest. On Jan. 16, 2017, Roskosmos announced that the vehicle with a production number 735 would be used for the Soyuz MS-04 mission, instead of previous plans to fly Vehicle No. 734. Roskosmos said that the swap had not been due to "technical reasons," but in reality, it was caused by a leakage discovered in the thermal control system, SOTR, of Vehicle No. 734. As a result, the launch of the Soyuz MS-04 mission had to be postponed from March 27 until April 20, 2017, at the earliest, depending on the readiness of Vehicle No. 735. The subsequent mission of the Soyuz MS-05 spacecraft also had to be delayed from May 29 until around July 28, 2017.
