ASO-S is the first Chinese solar space mission, and has been officially approved at the end of 2017. Currently, it is in Phase-C and is expected to be launched around 2022. ASO-S has a solar-synchronous orbit with an altitude of 720 km. The scientific objectives of ASO-S are to study the relationships among solar magnetic field, solar flares, and coronal mass ejections (CMEs). The energies of solar flares and CMEs are now believed to come from the solar magnetic field. The simultaneous observations of the solar magnetic field, solar flares, and CMEs, and the researches on the relationship among them, are therefore of particular importance. To fulfill the scientific objectives, ASO-S consists of three payloads: Full-disk vector MagnetoGraph (FMG), Lyman-alpha Solar Telescope (LST), and Hard X-ray Imager (HXI), to measure solar magnetic fields, to observe CMEs and solar flares, respectively. This talk shows the current status of ASO-S and our science preparations for understanding solar eruptions with ASO-S. |
