BepiColombo set to enter Mercury orbit after eight-year slow cruise
After eight years of a slow, gravity-assisted cruise powered by ion propulsion, the European-Japanese BepiColombo spacecraft will enter Mercury’s orbit in November 2026—Mercury’s third close visit and second orbiter. The arrival is gradual due to a prior thruster issue fixed in 2024, and the two orbiters will then separate to study Mercury’s surface/interior and magnetic environment, with full science operations expected to begin in 2027.
