"，", Achieve new results!

my country's first solar detection science and technology test satellite "Xihe" achieved a series of results

Nearly a hundred solar explosion activities have been observed. For the first time, the fine structure of the solar Hα spectrum is obtained on the orbit, and the new satellite technology of my country's new satellite is further tested ... On August 30, the National Space Administration officially released the first solar detection science and technology test satellite in Beijing " The new achievements of the series of "Hepo".

The "Hehe" was launched on October 14, 2021. It operates in the solar synchronization track with an average height of 517 kilometers. The main scientific load is the solar Hα imaging spectrometer. Since the "Hehe" has been launched, the National Space Administration has organized task units such as Aerospace Science and Technology Group, Nanjing University, and the Chinese Academy of Sciences to successfully complete the testing and testing of the "Hehe" on orbit.

Zhao Jian, the director of the high -scoring special chief designer and deputy chief of the deputy general chief, and the director of the major special project center of the National Defense Science and Technology Bureau, introduced that as the first solar "photographer" in my country, after the early stage testing and debugging, the "Xihe" has successfully achieved it After the first time internationally space, the solar Hα wound spectrum scanning imaging, the international structure of the Sun Hα spectrum, SI Ⅰ Ⅰ and Fei spectrum in the international rail was first obtained in the orbit. According to the fine structure of these spectrum lines, high -precision full -day color balls and light ball Doppler speed fields can be performed. Activities that occur in the solar atmosphere can be recorded in detail to study the physical process of solar activity. At present, the "Hepo" is planned to carry out scientific observations every day in accordance with the established task plan. Nearly a hundred solar explosion activities have been observed. Related research work is carried out. Scientific data has been opened to the world.

In addition to the results obtained by Sun scientific detection, in terms of new satellite technical tests, "Xihe" has achieved the first international collaboration and non -contact "double super" (ultra -high -point accuracy, ultra -high stability) satellite platform technology In the rail performance verification and engineering application, the first international solar space Hα imaging spectrometer is applied, and the first internationally international frequency solar rate navigator is verified.

Zhao Jian said that the "dual -super" satellite platform solves the technical problem of "unpredictable and difficult control" of the traditional satellite platform micro -vibration. It adopts magnetic floating control technology to ensure that the load imaging is not affected by the platform vibration. "Quote", the level of gesture control of my country's satellite platform has been increased by 1 to 2 magnitude. In the future, the "Double Super" satellite platform technology will be promoted and applied in new aerospace missions such as high -resolution remote sensing, solar three -dimensional detection, and solar systemic planet discovery.

At present, the National Space Administration has organized a series of task plans such as the sun and ground L5, the sun exploration of the sun and the sun, and the sun's close detection. Evolution contributes to the development of human scientific civilization.
