First BepiColombo flyby of Mercury finds elec
BepiColombo, the joint European Space Agency (ESA) and Japanese Aerospace Exploration Agency (JAXA) mission, has revealed how electrons raining down onto the surface of Mercury can trigger high-energy auroras. The mission, which has been enroute to the Solar System’s innermost planet since 2018, successfully carried out its first Mercury flyby on 1 October 2021. An international team of researchers analysed data from three of BepiColombo’s instruments during the encounter. The outcomes of this study have been published today in the scientific journal, Nature Communications.
