ELECTROMAGNETIC STUDIES OF MARS



Main scientific objectives:

  • solar wind interaction with the Martian plasma environment; the structure of the bow shock and planetopause;
  • identification of instabilities in the ionosphere and magnetosphere;
  • study of waves of atmospheric origin generated by sand storms and lightnings;
  • global mapping of plasma convections;
  • distribution of thermal plasma temperature and density to an altitude of 300 km;
  • dynamic relationship between the upper atmosphere and the lower ionosphere.

    • COMPLEX includes :

  • electric field sensors (3 double Langmuir probes consisting of four noncoplanar identical spheres mounted on booms);
  • magnetic field sensor ( three orthogonal Search Coil (SC) sensors )
  • Langmuir Probe;
  • high frequency (HF) and mutual impedance (MI) probe;
  • analyzers of the frequency spectrum of physical parameters to be measured;
  • microprocessor system.



    • Parameters to be measured:
    Electric field, (Ex , Еу , Еz ),frequency range 0 - 2 x 105 Hz;
    Magnetic field, (Вх , Ву , Вz ), frequency range 10-1-2 x 103Hz;
    Electron number density, Ne
    Langmuir probe 10-105sm-3;
    mutual impedance probe 10-102sm-3 ;
    frequency range 0-103 Hz;
    Electron temperature, (Те ) 0,1-10 eV
    Mass 12kg
