ESA's Mercury Transfer Module supplied BepiColombo's solar-electric cruise propulsion and carried the MPO and Mio orbiters through the inner Solar System. Its xenon ion thrusters reduced the propellant needed for the journey. The module successfully separated from the orbiter stack on 3 September 2026, completing its transfer role before Mercury orbit insertion.
Future launches and major activity directly linked to this vehicle family.
