摘要

The Chinese Hα Solar Explorer (CHASE) 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 Hα waveband.This paper briefly introduces CHASE/HIS including its scientific objectives,technical parameters,scientific application system,etc.The CHASE mission is scheduled to launch in 2021.It will complement the observations by on-orbit solar spacecraft (such as SDO,IRIS,STEREO and PSP),as well as future solar missions of the Solar Orbiter and Advanced Space-based Solar Observatory (ASO-S).
