Scope 
Mercury, the innermost planet in our Solar System, with its unique features, holds vital clues to understanding the evolution of terrestrial planets and the solar system. NASA's Mariner-10 and MESSENGER missions provided valuable insights but also left outstanding questions. These will soon to be addressed by the joint ESA-JAXA two spacecraft mission, BepiColombo, which is currently en route to Mercury and has already completed all flybys, and the two BepiColombo orbiters will arrive at Mercury in November 2026. This session welcomes contributions on all aspects of Mercury's environment, including its origin, formation, geology, surface composition, interior structure, exosphere, magnetosphere, gravity, and magnetic fi elds, as well as their coupling using various research methods such as modeling, laboratory experiments, and observations (ground-based, remote-sensing, and in-situ). We also encourage early analyses of BepiColombo flyby data and discussions regarding future missions to Mercury.
