Thermal Feasibility Study on the BepiColombo/MMO Spacecraft 2002-01-2274

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.
