China on 14 October 2021 sent its first solar exploration satellite into space from the Taiyuan Satellite Launch Center in northern Shanxi Province. The satellite was launched aboard a Long March-2D rocket and entered its planned orbit successfully.


  1. Ten small satellites including an orbital atmospheric density detection experimental satellite and a commercial meteorological detection constellation experimental satellite were also sent into space using the same carrier rocket.
  2. The satellite will operate in a sun-synchronous orbit at an altitude of 517 km, with a solar space telescope as its primary scientific payload.
  3. It will help researchers observe changes in the Sun during solar flares, such as changes in its atmospheric temperature and velocity.
  4. The satellite's design includes the separation of its platform cabin and payload cabin, thus ensuring the ultra-high pointing accuracy and stability of the payload.
  5. It was the 391st flight mission of the Long March carrier rocket series.
