BepiColombo is a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) to the planet Mercury.[4] The mission comprises two satellites launched together: the Mercury Planetary Orbiter (MPO) and Mio (Mercury Magnetospheric Orbiter, MMO).[5] The mission will perform a comprehensive study of Mercury, including characterization of its magnetic field, magnetosphere, and both interior and surface structure. It was launched on an Ariane 5[2] rocket on 20 October 2018 at 01:45 UTC, with an arrival at Mercury planned for on 5 December 2025, after a flyby of Earth, two flybys of Venus, and six flybys of Mercury.[1][6] The mission was approved in November 2009, after years in proposal and planning as part of the European Space Agency's Horizon 2000+ programme;[7] it is the last mission of the programme to be launched.[8]
On May 15, 2024 an ESA press release reported that a "glitch" prevented the spacecraft's thrusters from operating at full power during a scheduled manoeuvre on April 26.[9]
