About this launch
BepiColombo is a joint mission of the ESA and the JAXA to the planet Mercury. The mission comprises two satellites to be launched together: the Mercury Planetary Orbiter (MPO) and the Mercury Magnetospheric Orbiter (MMO). The mission will perform a comprehensive study of Mercury, including its magnetic field, magnetosphere, interior structure and surface.

MTM's selfie footage of BepiColombo's eight-year journeyWitness how over the last eight years, the ESA/JAXA BepiColombo mission has been travelling through the inner Solar System and aligning itself with Mercury's orbit. So far, it has travelled 9.9 billion km and completed nine 'planetary flybys' to help steer its way. In the video, you can see the spacecraft fly past Earth once, Venus twice, and Mercury six times.
BepiColombo begins Mercury arrival with MTM separation successOn 3 September 2026 at 15:49 CEST, the European Space Agency's BepiColombo Mission Control Team at the European Space Operations Centre (ESOC) received the signal they had been waiting for – BepiColombo’s Mercury Transfer Module (MTM) successfully separated from the spacecraft stack. This landmark achievement for the ESA and Japan Aerospace Exploration Agency (JAXA) mission marks the first step of BepiColombo's long-awaited arrival at Mercury.
