7. Advanced Space-based Solar Observatory (ASO-S)
Science: exploring solar eruptions and their origins
Payloads
FMG full-disc vector magnetograph
LST Lyman-alpha solar telescopes
HXT hard X-ray imager
Orbit solar synchronous
Altitude km
Inclination: degree
Launch year
Mission duration > 4 years

8. FMG: full-disc vector magnetograph

9. LST：Lyman-alpha Solar Telescopes
To observe CMEs continuously from solar disk to a few solar radii, another payload LST will be on board. It comprises three telescopes observing in Lyman-alpha and white light: SDI (solar disk imager), SCI (solar coronagraph imager), and WST a full-disk white-light solar telescope for the purpose of calibration of SCI.
