Mio Instruments
The Mio orbiter payload consists of a set of instruments for plasma, field and particle measurement to study the processes coupling Mercury's surface, magnetosphere and the solar wind.
The instrument subsystems are:
- An instrument suite to measure charged particles (MPPE, Mercury Plasma Particle Experiment) comprising:
- two Electron Spectrum Analyzers (MEA)
- a Mass Spectrum Analyzer (MSA)
- a Solar Wind Analyzer (MIA)
- a High Energy Particle Instrument for electrons (HEP-e)
- a High Energy Particle Instrument for ions (HEP-i)
- an Energetic Neutral Analyzer (ENA)
- Two three-axis Magnetic Field Sensors (MGF)
- A set of instruments to measure plasma waves (PWI, Plasma Wave Investigation) comprising:
- two dipole antennas: WPANT (Wire Probe Antenna)
- a double probe antenna: MEFISTO (Mercury Electric Field In Situ Tool)
- an electric field analyser: EWO
- a sensor to measure the magnetic field components along three axes: SC (Search Coil)
- an instrument to measure active plasma: AM²P
- a spectrometer to measure radio waves and thermal electrostatic noise: SORBET (Spectroscopie Ondes Radio and Bruit Electrostatique Thermique)
- A dust detector: MDM (Mercury Dust Monitor)
- An imaging spectrometer for the exosphere: MSASI (Mercury Sodium Atmosphere Imager).
The mass and power allocations for this payload are limited to 40 Kg and 53 W.
