BepiColombo stack

The complete BepiColombo spacecraft stack on 5 July 2017.

From bottom to top: the Mercury Transfer Module (sitting on top of a cone-shaped adapter, and with one folded solar array visible to the right); the Mercury Planetary Orbiter (with the folded solar array seen towards the left, with red protective cover), and the Mercury Magnetospheric Orbiter (MMO).

The Mercury Magnetospheric Orbiter’s Sunshield and Interface Structure (MOSIF) that will protect the MMO during the cruise to Mercury is sitting on the floor to the right.
