The crew of Soyuz МS-04 is approved by the State Commission

April 19, 2016

Today, on April 19, the State Commission at the Baikonur launch site approved the main and the backup crew assignments of the manned transport vehicle of the new series Soyuz МS-04 and confirmed the readiness of the integrated space launch system Soyuz-FG/Soyuz МS-04 and the ground infrastructure for the launch under the ISS program.

The prime crew of transport manned vehicle Soyuz MS-04 includes ROSCOSMOS cosmonaut Fedor YURCHIKHIN and NASA astronaut Jack FISHER. Their backups are ROSCOSMOS cosmonaut Sergei RYAZANSKY and NASA astronaut Randolph BRESNIK.

Upon completion of the State Commission session the members of the prime and backup crews answered questions from the Russian and foreign journalists at the traditional pre-flight press conference.

The launch vehicle with Soyuz МS-04 was rolled out from the integration and test building and erected at the launch pad of Site No.31 at Baikonur Cosmodrome on April 17. The spacecraft launch is scheduled on April 20.

The transport manned vehicle Soyuz MS developed and built by RSC Energia is designed to deliver the crews of up to three and their accompanying cargos to the International Space Station (ISS), as well as to return them to Earth. When attached to the ISS, it also serves as a crew rescue vehicle and is kept permanently ready for emergency crew return to Earth.

The new-series spacecraft Progress MS and Soyuz MS is a result of a radical upgrade of Progress M and Soyuz TMA spacecraft. The onboard command radio system Kvant-B was replaced with an integrated command and telemetry system with an additional telemetry channel. The new command radio link receives signals via relay satellites Luch-5, thanks to which the radio coverage zone for the spacecraft was significantly increased up to 70% of an orbit. The spacecraft are equipped with an advanced onboard radio system for rendezvous and docking Kurs-NA. As compared to the earlier version of Kurs-A, it has improved mass-dimensional characteristics and makes it possible to exclude one of the three radio antennas from the equipment configuration. Instead of the analog TV system Klyost, the spacecraft is using a digital TV system, which enables to maintain communication between the spacecraft and the station via the space-to-space communication system. The onboard equipment of the Soyuz MS and Progress MS series spacecraft includes a new Digital Backup Loop Control Unit developed by RSC Energia, an upgraded Rate Sensor Unit BDUS-3A and a LED headlight SFOK. Thanks to the use of the new ground and onboard radio systems, it became possible to use state-of-the-art data transmission protocols, which resulted in improved operational stability of the spacecraft control system.

Most of the technical solutions incorporated in the design of Soyuz MS and Progress MS spacecraft will be used in development of the manned transport vehicle of a new generation that is being developed by RSC Energia.


RSC Energia is the leader in the rocket and space industry, and the prime contractor for manned space systems. The Corporation conducts work on the development of unmanned space and rocket systems (launch vehicles and orbital transfer vehicles), and high-technology systems for various non-space applications. Since August 2014, the Corporation is headed by Vladimir Lvovich Solntsev.


SC ROSCOSMOS is a State Corporation that was established in August 2015 to implement a comprehensive reform of the Russian rocket-and-space industry. State Corporation ROSCOSMOS ensures the implementation of the Russian government’s space program and its legal regulation. ROSCOSMOS is also placing orders for the development, manufacture and supply of space equipment and space infrastructure objects. The state corporation is also responsible for international space cooperation and arranging conditions for the future use of results of space activities in the social and economic development of Russia.
