What is the name of the first solar exploration satellite?

The first solar exploration satellite is called Xihe.

The scientific name of "Xihe" is called the Solar Hα (Hydrogen Alpha) Spectral Detection and Double Super Platform Science and Technology Experiment Satellite. It was launched on October 14, 2021 and operates at an average altitude of With a sun-synchronous orbit of 517 kilometers, the main scientific payload is the Solar Hα Imaging Spectrometer. On August 30, 2022, the results of my country's first solar exploration science and technology experimental satellite "Xihe" were officially released. As my country's first dedicated solar "photographer", the "Xihe" has achieved the world's first space-based solar hα band spectral scanning imaging, which is equivalent to a "CT" scan of the sun's lower atmosphere.
