Figure 1: Mio
The plasma particle instruments (MPPE : MEA, MIA, MSA, HEP-e, HEP-i, ENA), magnetometer (MGF), and plasma wave and electric field instruments (PWI) mounted on Mio, will work together to understand the various physical phenomena occurring in the Mercury's magnetosphere. Mercury Sodium Atmosphere Spectral Imager (MSASI) will study emissions from Mercury’s thin atmosphere to shed light on the mysteries of the atmosphere's production mechanisms. The Mercury dust monitor (MDM) will observe the dust of the Solar System's innermost edge about which hardly anything is known. The radiation monitor (SPM) provides data about the solar energetic particle event.
