The thermal feasibility of BepiColombo MMO (Mercury Magnetospheric Orbiter) is shown. The temperatures of upper and lower decks on which instruments are located are controlled with in the allowable limit: -30 to 60 degrees C. The battery temperature is also controlled from 0 to 20 degrees C. Because MMO is spin-stabilized spacecraft, MMO requires the sun-shield and the radiator-shield in the cruise phase (Earth to Mercury) in which MMO is 3-axis stabilized, to avoid the exposure to the direct solar flux.
