Spacecraft
    Космический полет
    "Vostok" is the name of the series of the Soviet one man  spacecraft and the program  of the low earth orbit flights. These spacecraft were built up under the direction of Korolyov S.P.

    The aims of the "Vostok" programme were as follows:

    • investigate orbital flight effects on physical status and performance of a cosmonaut;
    • test the spacecraft design principles;
    • work out the future spacecraft design and systems.
    Main characteristics:
     
    • Weight
    		 - 4,73 tons;
    • Maximal mission duration
    		 - 5days.;
    • Length (without antennas)
    		 - 4,4meters;
    • Maximal diameter
    		 - 2.43meters.
    Complement:

    The "Vostok" spacecraft consists of two main modules: a descent (orbital) module (DM) and instrument module (IM). These modules are connected together by metal webbing and pyrotechnic latches.

    The "Vostok" spacecraft is equipped with:

  • automatic and manual control system;
  • automatic orientation to the Sun and manual orientation to the Earth system;
  • life support system (LSS);
  • electric power supply system;
  • temperature control system;
  • touchdown system;
  • radio telemetry equipment;
  • command radio link;
  • TV system intended for observing a cosmonaut from the ground;
  • orbital parameters control and spacecraft direction finding radio system;
  • deorbit propulsion system TDU-1.
