BepiColombo is Europe's first mission to Mercury. It will set off in 2014 on a journey to the smallest and least explored terrestrial planet in our Solar System. When it arrives at Mercury in November 2020, it will endure temperatures in excess of 350°C and gather data during its 1 year nominal mission, with a possible 1-year extension. The mission comprises two spacecraft: the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). BepiColombo is a joint mission between ESA and the Japan Aerospace Exploration Agency (JAXA), executed under ESA leadership.
