A major separation
BepiColombo separated from its Mercury Transfer Module on 3 September, ESA reported on 7 September. The mission had travelled for almost eight years, covering roughly 9.9 billion kilometres and completing nine planetary fly-bys.
Arrival is a sequence
The spacecraft was still around three million kilometres from Mercury at the time described by ESA. Separation should not be confused with entering orbit. The mission’s plan calls for Mercury orbit insertion on 21 November, followed by further changes to position its scientific orbiters.
The next milestones
ESA’s schedule puts Mio’s release in early December, the final orbit for the Mercury Planetary Orbiter in March 2027 and scientific operations in April. Each remains a planned step. The successful separation removes one important dependency, but the mission still has demanding navigation work ahead.
