An ESA–Japanese mission to the planet Mercury, planned for launch in 2014, arriving at Mercury in 2020. It will consist of two orbiters, the Mercury Planetary Orbiter (MPO) to study Mercury's surface and the Mercury Magnetospheric Orbiter (MMO) to study its magnetosphere and space environment; the magnetosphere orbiter will be provided by Japan. The mission is named after the Italian mathematician and engineer Giuseppe (‘Bepi’) Colombo (1920–84), who first explained Mercury's unique rotation.
