Hermean Environment Working Group

The BC mission includes two spacecraft and a complete suite of instruments which will permit to investigate the complex Hermean environment with unprecedented detail.

The role of the Hermean Environment Working Group is to keep the scientific community which is interested in the Mercury's environment linked and updated on the recent results, promoting collaborative studies.

The goal of the WG is to identify scientific topics that need common measurements, to define operation modes necessary for achievement of these tasks and the best operative way to archive and to visualize data from different instruments.

Primary Questions

  1. What was the evolution of Mercury after its early formation?
  2. What was the effect of the external environment?
  3. How did the internal magnetic field play a role in this evolution?

Practical Questions

  1. What are the current interactions between the surface, the exosphere and the magnetosphere of Mercury and between the planet and the interplanetary medium?
  2. What coordinated observations could shed light on this unknown environment?
