BepiColombo: A visit to Mercury

Abstract
BepiColombo is the planetary mission of the Cosmic Vision Programme of the European Space Agency (ESA), devoted to the thorough exploration of Mercury and its environment. It will be carried out as a joint project between ESA and JAXA (Japanese Aerospace Exploration Agency). BepiColombo consists of two spacecraft, the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). The MMO studies the wave and particle environment of the planet, while the MPO is dedicated to the characterization of Mercury itself. Both spacecraft will be in dedicated orbits that have been optimized for their tasks. They will be launched together on a single Soyuz-Fregat in July 2012 and reach Mercury about 4 years later. Then BepiColombo will start its one year mission, which will provide the detailed information necessary to understand the process of planetary formation and evolution in the hottest part of the proto-planetary nebula as well as the similarities and differences between the magnetospheres of Mercury and the Earth.
