The European Space Agency and the Chinese Academy of Sciences launched the SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) mission, their first fully joint space mission.
The mission carries the world’s first space-borne Soft X-ray Imager (SXI) to study the interaction between solar wind and Earth’s magnetosphere.
SMILE aims to capture global X-ray and ultraviolet images of Earth’s magnetic shield during solar activity and space weather events.
The mission includes four scientific payloads: Soft X-ray Imager (SXI), Ultraviolet Aurora Imager (UVI), Light Ion Analyser (LIA), and Magnetometer (MAG).
The 2,600-kg satellite will operate in a highly elliptical orbit about 1.21 lakh km above Earth’s North Pole.
The mission will help improve space weather forecasting and protect satellites, Global Positioning System (GPS), power grids, and communication systems from solar storms.
