Mercury at the dawn of Bepi-Colombo’s era: Interdisciplinary exploration inside and out

Session ID#: 157263

Session Description:
NASA's MESSENGER mission revolutionized our understanding of Mercury's surface, interior, exosphere, magnetosphere, and heliospheric environment. That understanding will soon take a major step forward with data from the flybys of Mercury by the ESA-JAXA BepiColombo dual spacecraft mission, subsequent flybys, and eventual orbit. In this session, we welcome all contributions on data analysis, laboratory measurements, ground-based observations, analog studies and theoretical developments that build on the current state of knowledge of Mercury, as well as papers that focus on BepiColombo measurements collected during the recent Mercury flybys. The topics of interest for this session include the geology, geochemistry, geophysics, exospheric dynamics, and surface-exosphere-magnetosphere coupling of Mercury. We also welcome papers discussing how outstanding questions about Mercury can be addressed by future observations expected from BepiColombo.
