SMILE (spacecraft)

SMILE (Solar wind Magnetosphere Ionosphere Explorer) is a planned mission by the European Space Agency and the Chinese Academy of Sciences. SMILE will for the first time take a picture of the Sun's magnetosphere. 

The questions that SMILE will answer are:

 What are the versions of the dayside solar wind or the magnetosphere interaction?
 What is the substorm cycle?
 Ho do the coronal mass ejection storms arise and what is their connection to solar substorms?
As of March 2025, SMILE is going to launch in late 2025.
