This exploded view shows BepiColombo in its cruise configuration. Visible from the bottom are: the BepiColombo transfer module, the Mercury Planetary Orbit (MPO), the sun shield and the Mercury Magnetospheric Orbiter (MMO).

The transfer module is provided with solar-electric propulsion and chemical propulsion units. The former will be used during the cruise to destination; the latter will be used after launch to boost up the orbit to the Moon's altitude for the planned lunar gravity-assist.
