Objectives and Applications
SMILE will investigate the interaction between Earth’s protective shield – the magnetosphere – and the supersonic solar wind. The mission is expected to make an important contribution to our understanding of space weather and, in particular, the physical processes taking place during the continuous interaction between the solar wind and the magnetosphere.
