After eight years of travelling through the inner Solar System, BepiColombo is arriving at Mercury. This page will show the latest updates throughout the mission’s arrival.
BepiColombo is a world-class science mission led by the European Space Agency (ESA) in close collaboration with the Japan Aerospace Exploration Agency (JAXA). It will be the first mission to orbit Mercury with two spacecraft, with ESA’s Mercury Planetary Orbiter (MPO) and JAXA’s Mercury Magnetospheric Orbiter (Mio) orbiting the planet at the same time.
The ‘arrival phase’ begins with the separation of the Mercury Transfer Module (MTM) from the spacecraft stack on 3 September 2026. The composite spacecraft will enter orbit around Mercury on 21 November 2026, and MPO and Mio will separate from each other on 9–10 December 2026. The mission’s science phase is set to begin in April 2027.
