The Advanced Space-based Solar Observatory (ASO-S) is a comprehensive solar observatory scheduled for launch in October 2022. The main scientific objectives of ASO-S are solar flares, coronal mass ejections (CMEs), solar magnetic field, and their relationships. Three scientific payloads (FMG, LST, and HXI) are therefore deployed on board the ASO-S to observe full-disk solar vector magnetic field, solar hard X-ray bursts, and Lyman-α images up to 2.5 solar radii simultaneously. The Chinese Hα Solar Explorer (CHASE) was launched on October 14, 2021, aiming at testing a new satellite platform and conducting solar observations. The scientific payload Hα Imaging Spectrograph (HIS) onboard the CHASE provides, for the first time in space, the full-disk spectroscopic imaging observations at Hα waveband. In this talk, I will present a brief introduction to the two missions, the early results of CHASE observations, and the status of ASO-S mission.
