The first new series Progress MS vehicle berthing to the ISS occurred

December 23, 2015

Today, on December 23 the first new modification Progress MS cargo transport vehicle developed and produced by RSC Energia successfully docked to the Russian Segment of the International Space Station (ISS).

The cargo vehicle docking to Docking Compartment (DC1) Pirs is performed in the unmanned mode on December 23 at 13:27:01 Moscow Time in the 34-th orbit of the flight. The ISS crewmembers monitored the berthing process from the Station.

The Soyuz-2.1a launch vehicle (LV) with the Progress MC CTV was launched from site No.31 of the Baikonur Cosmodrome on December 21 at 11:44:39 Moscow Time. The vehicle made a two-day rendezvous with the ISS.

Onboard the vehicle there are 2436 kg of different cargo including 1252 kg of dry cargo, 718 kg of propellant in the refueling system tanks, 420 kg of water and 46 kg of compressed gases (air and oxygen).

The vehicle delivered to the ISS more than a ton of cargo for Service Module (SM) Zvezda including a life-support system and the individual protection aids for cosmonauts, storage batteries for power supply system, sanitary-hygienic and medical equipment, consumables for gasanalytical equipment and thermal control system, onboard system maintenance and repair aids, fire extinguishers, etc.

For the Station crewmembers the following is prepared: containers with food rations, fresh food kit and parcels with personal things. In the cargo compartment of the vehicle there are sets of onboard documentation, completing parts and power supply components for video and photographic equipment, hard disks, hardware for science research and experiments.

Onboard the Progress MS CTV there are also 127 kg of the U.S and European cargo, in particular the habitable environment monitoring aids, equipment and instruments for extravehicular activity, the weightlessness prevention aids, science hardware, the U.S. food and clothes for the Russian crewmembers.

Transport vehicles of a new modification such as Progress MS and Soyuz MS are developed as a result of the great modernization of the Progress M and Soyuz TMA vehicles.

The onboard command-radio system Kvant-B is replaced by single command-telemetry system (SCTS) with an additional telemetry channel. A new command radio link provides the signal reception via the Luch-5 relay satellites, due to which the vehicle radio visibility zones will be considerably expanded up to 70% of the orbit duration.

The new modification vehicles are completed with modern onboard radio system for rendezvous and docking Kurs-NA. As compared with more earlier Kurs-A version, it has the improved weight-dimension characteristics and allows to remove from the vehicle equipment one of three radio antennas.

Instead of analog television system Klest the following is used in vehicles: a digital television system which allows to maintain communication between the vehicle and the Station via board-to-board radio link.

A new digital reserve loop control unit (RLCU) developed by RSC Energia, modernized angular rate sensor unit ARSU-3A and light-emitting diode headlight SFOK became a part of the vehicle onboard equipment of the Soyuz MS and Progress MS modifications instead of the equipment taken out of production.

Due to the use of the new ground and onboard radio systems it became possible to use up-to-date protocols of information transfer, as a result of which the vehicle control system operation stability increased.

The majority of technical decisions inherent in the Soyuz MS and Progress MS structure will be used when creating a new generation manned transport vehicle (MTV) which is developed by RSC Energia.


OAO RSC Energia is a leading enterprise of rocket-space industry, the prime organization for manned space systems. The Corporation is working to develop unmanned space and rocket systems (launch vehicles and inter-orbital transfer), high-tech systems for various applications to be used in non-space fields. Since August 2014 the Corporation is headed by Vladimir Solntsev.
