China has released the results of its first solar observation satellite named “Xihe” with breakthroughs in technology verification and data shared with the international community.

The satellite has obtained the world’s first H-alpha spectral scanning imaging with ultra-precision after observation on almost 100 solar burst activities since it was launched into a sun-synchronous orbit kilometers above the Earth in October 2021.

“It is like a deep CT scan to the entire sun. And it aims to find the physical laws of the solar atmosphere and the solar activities,” said Ding Mingde, chief scientist of Xihe solar observation satellite. “It will help us prevent the harms that the solar activities might bring to us.”

The satellite made two key breakthroughs of “ultra-precision” and “super stability,” according to Chen Jianxin, general director of the Xihe satellite. “It increases one to two orders of magnitude compared with any satellites we are using now. That means a better environment for the payload of camera which enables better images.”

And the probing results are open to scientists around the world and can be downloaded from the official website.

“Solar probe is the common cause of all human beings. We must take advantages of these data and resources to provide the bountiful research materials for the solar physicists around the world,” said Zhao Jian, director of Earth Observation System and Data Center, China National Space Administration. “This will help them find better scientific discoveries and better serve the human society.”
