Shulou(Shulou.com)11/24 Report--

CTOnews.com, February 15, the National Space Science Center of the Chinese Academy of Sciences officially announced that the SMILE mission satellite team (Institute of Micro Satellite Innovation of the Chinese Academy of Sciences) went to the European Space Agency (ESA) European Space Technology Center (ESTEC) to carry out satellite initial satellite and arrow joint test, and has successfully completed interface docking, satellite separation and impact test.

According to reports, this is the first time that China and Europe have realized the whole satellite joint assembly and satellite arrow test. This is the first China-EU on-site communication activity since the SMILE Task-level preliminary Design Review (M-PDR) in January 2020, and it is also a milestone in the development of SMILE tasks.

In this experiment, the SMILE structure satellite developed by the Micro Satellite Innovation Institute of the Chinese Academy of Sciences is used to dock with the flight adapter and envelope of Arianespace. Participating in the joint test are the Micro Satellite Innovation Research Institute of the Chinese Academy of Sciences, the European Space Agency, Ariana Space Company (Arianespace), Airbus Defense and Space Company, and so on.

This test achieved three domestic firsts: Chinese satellites were exported and transported to ESA for the first time; Chinese satellite teams integrated and assembled the whole satellite at ESA for the first time; and Chinese satellites conducted docking and separation impact tests with European carriers for the first time.

According to the development plans of China and Europe, the SMILE task force will go to Spain in April to carry out docking tests with the European payload module, and in May and September to Germany to carry out docking tests with European measurement and control stations and data transmission stations, so as to further consolidate the prototype development work and ensure that the satellite is launched on time.

According to public data, the solar wind-magnetosphere interaction panoramic imaging satellite (Solar wind-Magnetosphere-Ionosphere Link Explorer,SMILE) project is the first space science exploration mission conducted in deep cooperation between China and the European Space Agency.

The scientific goal of the satellite is to detect the large-scale structure and basic model of solar wind-magnetosphere interaction, to recognize the overall variation process and periodic variation of magnetospheric substorms, and to explore the occurrence and development of magnetic storms driven by coronal mass ejection events.

SMILE satellite can carry out X-ray imaging of the earth's magnetic sheath and polar tip for more than 40 hours, ultraviolet auroral imaging of the global auroral distribution, and real-time in-situ detection of plasma and magnetic field in the solar wind and magnetosphere to reveal the process and variation of the interaction between the solar wind and the magnetosphere.

CTOnews.com found that the SMILE satellite project is generally composed of the National Space Science Center of the Chinese Academy of Sciences and ESA, the satellite as a whole is the Institute of Micro Satellite Innovation of the Chinese Academy of Sciences, and the carrier rocket uses the European Ariana Space Company Vega-C carrier rocket, which is scheduled to be launched at the Kulu launch site in April 2025.
