The working orbit is a 19 Re 5000 km HEO with 4 scientific instruments: Soft X-ray Imager(SXI), Ultra-Violet Imager(UVI), Magnetometer(MAG) and Light Ion Analyzer(LIA). SMILE aims to understand the interaction between the solar wind and the Earth's magnetosphere through the images of SXI and UVI and in-situ measurement from LIA and MAG. After the kick-off in 2016, the SMILE project went to Phase A study. The mission adoption is scheduled for November 2018, with a target launch date in 2022–2023.In this paper, the background of the mission, scientific objectives, the design and characteristics of scientific instruments and the mission outline will be introduced in details.展开更多
