Advanced Space-based Solar Observatory
Chinese satellite launched in 2022
From Wikipedia, the free encyclopedia
The Advanced Space-based Solar Observatory, also known as ASO-S,[2] is a satellite mission aimed at improving observations of solar activity. The satellite was launched using the CZ-2D rocket at 07:43:55 local time on October 9, 2022[2] (8 October 2022 at 23:43 UTC).[3] The satellite is a part of the Kuafu project, and is also unofficially known as Kuafu-1 (夸父一号).

ASO-S was first proposed by the Chinese solar physics community in 2010[1] or 2011,[2] and was formally approved by the Chinese Academy of Sciences in 2017. The mission is aimed at studying the Solar Magnetic Field, Coronal Mass Ejections and Solar flares.[2]
The Chief Scientist is Weiqun Gan of the Purple Mountain Observatory, while the chief designer and the chief administrator are both associated with the National Space Science Center, which is part of the University of the Chinese Academy of Sciences.[3]
