The BepiColombo mission will place two orbiters around Mercury: the Mercury Planetary Orbiter (MPO), that will map the planet, and the Mercury Magnetospheric Orbiter (MMO), that will investigate its magnetosphere.

As one of the scientific objectives, BepiColombo will make a complete map of Mercury at different wavelengths. The mission will map the planet's mineralogy and elemental composition and determine whether or not its interior is molten.

BepiColombo will provide information on the composition and history of Mercury, and the history and formation of the inner planets in general, including Earth.
