Soyuz MS
Part of Soyuz Family
Russian three-crew manned spacecraft. Evolved from the Soyuz TMA incorporating numerous minor improvements identified over time. New digital computer, more redundancy in attitude control and docking systems, modernized electronics and solar power. Launched 2016 - on.

First Launch: 2016-07-07. Last Launch: 2017-04-20. Number: 4 .

The improvements were as follow:

  • Solar cell efficiency increased from 12% to 14% (from 12%) solar panel area increased by 1.1 m2
  • A fifth 155 Ampere-hour battery added
  • Additional micro meteoroid protection blankets on the orbital module at the request of NASA
  • Introduction of the TsVM-101 computer, with a mass of 8.3 kg vs. the 70 kg of the Argon-16 it replaced
  • Rearranged attitude control thrusters, allowing docking and undocking with one failed thruster or de-orbit with two failed thrusters.
  • Improved redundancy using dual independent propellant supply subsystems.
  • Addition of a Satellite Navigation System (ASN-K) using GLONASS and GPS signals for autonomous navigation. It is linked to a COSPAS-SARSAT transponder to transmit the location of the capsule within 10 m at the time of parachute deployment and landing.
  • Integrated communications and telemetry system, EKTS, that can use Luch, TDRS, or EDRS satellites for relay to ground stations
  • Kurs-NA automatic docking system using all-Russian components and a single phased array antenna replacing three earliers antennae
  • Backup electric drive in the docking system
  • Digital television
  • LED powered external illumination system
  • A new flght data recorder recording voice and data during the mission.

Crew Size: 3. Orbital Storage: 200 days. Habitable Volume: 9.00 m3. Spacecraft delta v: 390 m/s (1,270 ft/sec). Electric System: 0.70 average kW.
