  • 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.
