In a remarkable achievement for space exploration, the European and Japanese space agencies have announced the successful completion of the final flyby of Mercury by their joint mission, the BepiColombo spacecraft.

This milestone was reached on January 9, 2025, marking a significant step forward in one of the most ambitious planetary exploration missions to date.

Launched in 2018, BepiColombo has been meticulously maneuvering through the solar system, executing a series of precise flybys to gain the momentum needed for its ultimate mission: orbiting the innermost planet, Mercury.

During its close encounter, the spacecraft soared as near as 183 miles above Mercury's night side, affording scientists some of the most detailed photographs of the planet’s north pole to date.

The European Space Agency (ESA) has released these awe-inspiring images, which reveal the mysterious and permanently shadowed craters of Mercury’s north pole.

The area, enveloped in perpetual darkness, presents a unique opportunity for scientific study, as the lack of sunlight preserves historical records of the solar system's formation.

In addition to the shadowed craters, BepiColombo’s cameras captured views of Mercury's neighbouring volcanic plains and the planet's largest impact crater, an expansive geological feature spanning more than 930 miles.

These images will pave the way for further understanding of the planet’s surface and its geological history.

This flyby was the sixth and final one for BepiColombo, an indispensable series of maneuvers designed to guide the spacecraft into Mercury's orbit.

The spacecraft is equipped with two orbiters—one developed by ESA and the other by the Japan Aerospace Exploration Agency (JAXA)—which are set to split and operate independently, focusing on circling the planet’s poles once orbital insertion has been achieved next year.

Named in honor of Giuseppe (Bepi) Colombo, a renowned 20th-century Italian mathematician, the mission pays tribute to his pivotal contributions to space exploration.

Colombo significantly influenced NASA's Mariner 10 mission to Mercury in the 1970s with his insightful calculations on gravity-assist maneuvers.

Later, he contributed to the Italian Space Agency’s tethered satellite project, a vital component of US space shuttle missions.

As BepiColombo sets its sights on orbiting Mercury, scientists around the world are poised to acquire valuable data that will enhance our understanding of this enigmatic planet.

The forthcoming orbital phase will focus on studying Mercury's magnetic field, exosphere, and surface composition, promising to enrich our knowledge not only of Mercury itself but also of the solar system at large.
