MMO inside the sunshield
The full BepiColombo stack is complete with the addition of the sunshield that will protect JAXA's Mercury Magnetospheric Orbiter (MMO) en route to Mercury. The white dish on top of MMO is its deployable high-gain antenna.
BepiColombo is a joint endeavour between ESA and JAXA, the Japan Aerospace Exploration Agency. The Mercury Magnetospheric Orbiter sits at the top of the stack inside the sunshield, ESA's Mercury Planetary Orbiter is in the middle, and ESA's Mercury Transfer Module is at the bottom.
