The Interior of the Soyuz

The Soyuz capsule is divided in three modules: orbital module, descent module and instrumentation/propulsion module

The Soyuz spacecraft consists of three modules:

The Orbital Module

  • contains life support system equipment (water, food, toilet), rendezvous and docking equipment, vehicle system automatic equipment and a television camera
  • is the crew's living area during non-dynamic flight phases
  • is the crew's entry and exit during dock phase on the Space Station
  • separates from the Descent Module after undocking from the Space Station and burns up in the atmosphere upon re-entry

The Descent Module

  • is where the crew sits in a reclining position during ascent, orbital manoeuvres (correction burns, approach and docking, etc.) and re-entry
  • contains life support system equipment, autonomous flight devices and instrumentation (command panel) and the entry control system
  • is the only module with thermal protection for carrying the crew back to Earth

The Instrumentation/Propulsion Module

  • is divided into three compartments; the intermediate, instrumentation and propulsion compartments which contain oxygen tanks, electrical and thermal control systems, computers, thruster jets, infrared sensors, external radiators, and solar array attachments
  • separates from the Descent Module after undocking from the Space Station and burns up in the atmosphere upon re-entry
