8月30日，我国首颗太阳探测科学技术试验卫星“羲和号”成果正式发布，共创下5个国际首次。
自发射以来，“羲和号”按照既定任务计划开展科学观测，累计下传原始观测数据50Tbit，生成科学数据约300Tbit，对于后续开展太阳空间探测任务以及提升我国在空间科学领域国际影响力等具有重要意义。
作为我国首位太阳专属“摄影师”，“羲和号”成功实现了——
一、国际首次“双超”（超高指向精度、超高稳定度）卫星平台技术在轨性能验证及工程应用；
二、国际首次太阳空间Hα成像光谱仪在轨应用；
三、国际首次空间太阳Hα波段光谱扫描成像；
四、国际首次在轨获取太阳Hα谱线、SiΙ谱线和FeΙ谱线的精细结构；
五、国际首次在轨采用原子鉴频原理。
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 about 517 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 the 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."
科学数据向全球开放共享
目前，“羲和号”每天都在按照既定计划开展科学观测，已经观测到了近百个太阳爆发活动，相关研究工作正在进行。
据国家高分辨率对地观测系统总设计师兼副总指挥、国家航天局对地观测与数据中心主任赵坚介绍，我国在太阳观测领域发表论文数量已居世界第二位，但之前使用的数据均来自国外卫星数据。“羲和号”发射成功后，国家航天局牵头成立了卫星数据科学委员会，制定了数据政策，供国内外科学家研究、使用、共享卫星探测数据，力争产生更多的原创性科学成果，为人类科学事业做出中国贡献。目前，“羲和号”的科学数据已向全球开放共享。
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."
