Kuafu-1, the Advanced Space-based Solar Observatory (ASO-S), launched at 7:43 a.m. on October 9, 2022 from the Jiuquan Satellite Launch Center, has successfully entered its scheduled orbit, making the launch mission a complete success.

ASO-S satellite have been proposed for comprehensive solar exploration proposed by Chinese solar physicists. It is another satellite developed and launched as part of the space science pilot program of the Chinese Academy of Sciences following "Wukong", "Mozi", "Huiyan", "Shijian 10", "Taiji-1" and "Huairou-1". It marks another breakthrough for China's space-based solar exploration efforts.

The Lyman-alpha Solar Telescope (LST), developed by a team led by Prof. CHEN Bo, Deputy Chief Engineer in Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), is one of the three payloads on the ASO-S satellite.

LST is composed of a dual band corona imager, a solar disk imager and a white-light telescope. The Lyman-alpha corona imager adopts an innovative dual band design scheme and simultaneously images solar corona in 121.6nm and 700.0nm. The solar disk imager and white telescope both adopts an off-axis two-mirror reflective layout and covers the Lyman-alpha and 360 nm bands. They can simultaneously monitor the activities and changes of the Sun from the solar disk to the corona region of 2.5 solar radius, are going to provide data for scientific research and space weather forecasting.
