Xuntian Telescope The major aspects of the survey: Science: 17500 ° imaging : 255-1000nm, ≥6 filters, ≥25.5 m 17500° spect: 255-1000nm, R≥200, ≥22-23 m 400° deep imaging & spect: at least 1 m deeper Science: Cosmology: dark energy, dark matter, gravity, large scale structures Active galactic necleus Galactic astronomy Galactic structure ……. The telescope : Field of view:1.1 º Image resolution:0.15″ Pixel number:2.7G Image quality of the slitless spectrograph:better than 0.3″ Spectral resolution of the slitless spectrograph :R≥200
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 720 km Inclination: 98.2 degree Launch year 2022 Mission duration > 4 years
FMG: full-disc vector magnetograph
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. SDI SCI
