On October 1 2021, the joint European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) BepiColombo spacecraft successfully performed its first flyby of the solar system’s innermost planet, Mercury. The flyby is the first in a set of six such events BepiColombo will complete before entering orbit around Mercury in late 2025.

Following the flyby, initial science returns from different instruments onboard BepiColombo revealed interesting details about the environment surrounding Mercury, as well as details on the planet itself.
