China-Europe Space Mission SMILE Aims to Enhance Understanding of Earth's Magnetic Field
The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a collaborative space mission between the Chinese Academy of Sciences and the European Space Agency. This mission aims to study Earth's magnetic field response to solar storms in real-time, a phenomenon not yet fully observed. SMILE will be launched into an elliptical orbit, ranging from 5,000 kilometers over the South Pole to 121,000 kilometers above the North Pole, to provide a comprehensive view of how solar wind interacts with Earth's magnetosphere. This interaction can trigger geomagnetic storms, which pose risks to satellites and power grids. The mission, which began its study phase in 2016, was selected from 13 proposals in 2015. However, the launch, initially scheduled for April 9, has been postponed due to a technical issue, with no new date announced yet.
