Geophysics research on ISS Russian Segment

Impuls Experiment


Study of a capability to use the pulsed plasma injectors as the ionospheric disturbance sources and low-frequency electromagnetic wave sources; study of space environment disturbances by artificial plasma flows and their effect on radio waves propagation.


  • Delivery of PPI-SM science hardware as an assembly and equipment (devices and cables) for space experiment (SE) on the ISS RS.
  • Mounting of SE equipment and test setup connection for hardware mating with service systems (onboard equipment control system and onboard measurement system) inside the pressurized module.
  • Installation of hardware on universal work site (UWS-D) and cable running during extravehicular activity.
  • Test checks of the equipment operability.
  • Measurement of the ISS electrical background in a flight.

Science Hardware Used:

  • PPI-SM hardware as an assembly:
    • Pulsed plasma injector IPI-100
      for the pulsed plasma flows generation and injection into space;
    • Electrophysical parameters control complex
      to study electrophysical parameters near the surface of the ISS RS Service Module
  • Kit IMPULS SE Equipment;
  • Reprogrammable memory (2 pcs.);
  • Cable holder (3 pcs.)

Flight Equipment Used:

  • Power switching unit BSK-5V.

Expected Results:

  • Analysis of a capability to generate magnetosheric waveguides to develop new electromagnetic communication channels.
  • Reception of data for assessment of ultimate technogenic loads on ionospheric medium, changing its properties.

Experiment Results:

The scientific data bank generated by the investigator by the results of analysis and initial processing of telemetry information down linked to the ground via the onboard measurement telemetry system.
