China News Service, Beijing, October 9 (Reporter Sun Zifa) The Chinese Academy of Sciences (CAS) released a message on October 9 that at 7:43 Beijing time that day, a new space science satellite specially developed by the academy's space science pilot—— The advanced space-based solar observatory "Kufu-1" was launched at the Jiuquan Satellite Launch Center in China using a Long March 2D-type carrier rocket. A complete success.

　　The Advanced Space-based Solar Observatory (ASO-S), named after the traditional Chinese myth "Kuafu Chasing the Sun", named "Kuafu No. 1", is a comprehensive solar astronomy independently proposed by Chinese solar physicists. The special satellite for solar exploration is also another space science satellite developed and launched by the Chinese Academy of Sciences' space science pilot project following the "Wukong", "Mozi", "Huiyan", "Shijian 10", "Taiji 1" and "Huairou 1". Achieve a leap-forward breakthrough in China's space-based solar exploration satellites.

　　The "Kufu-1" satellite aims to detect the sun's "one magnetic and two storms" as its scientific goal. It will take advantage of the opportunity of the 25th peak year of solar activity to detect the two most violent eruptions on the sun - solar flares and coronal mass ejections. , as well as the simultaneous observation of the all-solar vector magnetic field, to study the formation, interaction and interrelationship of "one magnetic field", namely the solar magnetic field, and "two storms", namely flares and coronal mass ejections. to provide support for space-based severe weather forecasting.

　　The "Kwafu-1" solar exploration satellite is equipped with three payloads, the All-Solar Vector Magnetic Imager, the Lyman Alpha Solar Telescope and the Solar Hard X-ray Imager. On the platform, the simultaneous observation of the solar magnetic field, the non-thermal radiation of solar flares, the formation of the solar surface of the coronal mass ejection and the propagation of the near surface can be realized.

At the same time, with the help of the Lyman Alpha Solar Telescope, the "Kwafu-1" satellite will realize the simultaneous observation of the entire heliosphere and the corona in the Lyman alpha band for the first time.

The satellite has a design life of 4 years and operates in a sun-synchronous twilight orbit of about 720 kilometers.

　　China's comprehensive solar exploration satellite was finally named "Kuafu-1" after extensive registration.

Science popularization, a leading specialist in space science of the Chinese Academy of Sciences, said that, on the one hand, "Kuafu" is a well-known figure in Chinese mythology. The nation has been trying to unravel the mystery of the sun for thousands of years; on the other hand, it means that "Kuafu-1" will work with the future Chinese solar exploration satellite to open a new era of comprehensive solar observation in China.

In addition, the "Kuafu Chasing the Sun" for detecting the sun corresponds to the "Chang'e Flying to the Moon" for lunar exploration, which perfectly interprets the Chinese people's romantic feelings of loving nature and exploring nature.

　　It is understood that the National Space Science Center of the Chinese Academy of Sciences is responsible for the development and construction of the overall project and the ground support system. The Zijinshan Observatory is responsible for the development of satellite platforms and payloads, the scientific application system is in charge of the Zijinshan Observatory of the Chinese Academy of Sciences, the measurement and control system is implemented by the China Xi'an Satellite Measurement and Control Center, and the launch vehicle is developed and produced by the Eighth Research Institute of China Aerospace Science and Technology Corporation.

The satellite launch is the 442nd space flight of China's Long March series of launch vehicles.
