Mercury Magnetospheric Orbiter

Definition

The Mercury Magnetospheric Orbiter (MMO) is a planned spacecraft designed to study Mercury's magnetosphere, which is the region of space around the planet influenced by its magnetic field. The MMO will provide valuable insights into how solar wind interacts with Mercury's weak magnetic field, helping scientists understand both the planet's atmosphere and its geological history.
