BepiColombo nears Mercury orbital arrival after seven year journey
Paris, France (SPX) Nov 25, 2025 The ESA and JAXA BepiColombo mission is entering its final year of approach to Mercury, on track to reach orbit in November 2026 after launching in October 2018. The dual-spacecraft mission has already completed one flyby of Earth, two of Venus, and six of Mercury, collecting solar activity and magnetosphere data en route. Throughout its cruise, BepiColombo measured planetary magnetic environments, monitoring the Sun's influence on radio signals as well as Mercury's changing magnetic bubble. The m ... read more |

First BepiColombo flyby of Mercury finds electron rain triggers x-ray auroras
London, UK (SPX) Jul 19, 2023 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 stu ... read more 
ASU scientist uses NASA MESSENGER mission data to measure chromium on MercuryTempe AZ (SPX) Jul 11, 2023 The origin of Mercury, the closest planet to the sun, is mysterious in many ways.
