CHASE (Xihe)


CHASE (Chinese Hα Solar Explorer) is designed to test a newly developed satellite platform and conduct solar observations. The scientific payload of the satellite is an Hα imaging spectrograph (HIS), which can, for the first time, acquire full-disk spectroscopic solar observations in the Ha waveband.

It will complement the observations by on-orbit solar spacecraft (such as SDO, IRIS, STEREO, PSP and Solar Orbiter), as well as future solar missions of the Advanced Space-based Solar Observatory (ASO-S).
