BepiColombo Spacecraft Nearing Mercury After Decade-Long Journey
Two linked European and Japanese spacecraft, BepiColombo, have separated from their cruiser and are on the final stretch of their nearly decade-long voyage to Mercury, with orbital insertion expected in November.
Philadelphia, PA, September 3, 2026 — The BepiColombo mission, a collaborative effort between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), is approaching a critical milestone. The two spacecraft, linked together, have successfully separated from their cruiser. This separation marks the beginning of the final phase of their extensive journey to orbit Mercury.
The mission’s voyage has spanned nearly a decade, a testament to the complexities of interplanetary travel and the ambitious goals of the program. After years of coasting through the solar system, employing gravity assists from Earth and Venus, the spacecraft are now on the direct path towards the innermost planet of our solar system.
Orbital insertion into Mercury’s orbit is the next major objective. This maneuver is anticipated to occur in November. Successfully entering orbit around Mercury will be a significant achievement, paving the way for detailed scientific observations of the planet, which is known for its extreme temperatures and unique geological features.
The BepiColombo mission is designed to study Mercury from orbit. It consists of two orbiters: the ESA’s Mercury Planetary Orbiter (MPO) and JAXA’s Mercury Magnetospheric Orbiter (MMO), also known as MIO. The spacecraft were launched together atop an Ariane 5 rocket from Europe’s Spaceport in Kourou, French Guiana, in October 2018. The combined mission is designed to provide a comprehensive understanding of Mercury’s composition, magnetic field, and exosphere.
Specific details regarding the exact date of the orbital insertion in November, or the name of the cruiser from which the spacecraft separated, were not immediately available.
