 Experiment: MARIPROB

IONOSPHERIC PLASMA SPECTROMETERS

MEASUREMENTS OF MARS IONOSPHERE PARAMETERS



Main scientific objectives:Martian ionosphere and the cold plasma convection in the Martian magnetosphere.


MARIPROB measures the following ionospheric parameters:
  • electron number density;
  • electron temperature;
  • ion number density;
  • mass composition of major components;
  • full vector of the ion drift velocity.

    • Instrument consists of:

  • 2 identical ion energy spectrometers - a set of 30 Retarding Potential Analyzers without collectors sharing single MCP-based ion registration unit with 109 dynamic range for input ion flux;
  • Spherical Ion Probe (SIP)- a spherical retarding potential analyzer operating in a floating mode with periodic measurements of integral ion and electron spectra.



    • Main characteristics:
    Ion, electron number densities, Ni, Ne 0,1-5 x 105 cm-3
    Ion, electron temperature, Ti, Te <15000 К
    Cold plasma convection velocity 10 m/s - 35 km/s
