China News Service, Beijing, July 11 (Reporter Sun Zifa) Regarding the sun, which is closely related to the survival and development of the earth and human beings, there are myths and legends about Kuafu chasing the sun and Hou Yi shooting the sun in ancient China.
Today, China's first dedicated satellite for comprehensive solar exploration, the Advanced Space-based Solar Observatory (ASO-S), is scheduled to launch in October this year, which will start a new journey for China to explore the sun.
As a new member of the "big family" of China's scientific satellite series following "Wukong", "Mozi", "Huiyan" and "Taiji-1", this comprehensive solar exploration satellite also hopes to have a unique, easy-to-follow satellite Remember the Chinese nickname.

The Chinese Academy of Sciences (CAS) announced on July 11 that from that day to July 24, China's first dedicated satellite for comprehensive solar exploration, the "Advanced Space-Based Solar Observatory", solicited centralized nicknames from netizens around the world.
It is hoped that the names submitted by netizens will be highly in line with the scientific goals of the satellite, with concise text, easy to remember, easy to spread, and full of scientific and cultural connotations, showing the Chinese people's scientific exploration spirit and cultural confidence.
China's first dedicated satellite for comprehensive solar exploration, "Advanced Space-Based Solar Observatory", takes "one magnetic field and two storms" as its scientific goal. "One magnetic field" refers to the sun's magnetic field. Most solar activities are directly dominated by the sun's magnetic field. The "two storms" refer to the two most violent eruptions on the sun, namely solar flares and coronal mass ejections.

The "Advanced Space-Based Solar Observatory" has a design life of 4 years. It will take advantage of the 25th peak year of solar activity to conduct simultaneous observations of flares, coronal mass ejections and all-solar vector magnetic fields, and to study the origin and interaction of "one magnetic and two storms". The functions and interrelationships provide support for the severe weather forecast in space that seriously affects the normal life of human beings.
Gan Weiqun, the chief scientist of the "Advanced Space-Based Solar Observatory" and a researcher at the Purple Mountain Observatory of the Chinese Academy of Sciences, said that the space science satellite carries a total of 3 payloads, including the All-Solar Vector Magnetic Imager, the Lyman Alpha Solar Telescope and the Solar Hard X-ray Imaging The instrument will, for the first time, observe the full-solar vector magnetic field, the non-thermal radiation imaging of solar flares, the solar-surface formation and pericorona propagation of coronal mass ejections on a low-Earth-orbiting satellite platform, and achieve the first full-solar Lyman alpha band. Simultaneous observation of the surface and the corona.

After China's first comprehensive solar exploration satellite is put into orbit, it will generate about 500GB of detection data every day. All the satellite's scientific data and analysis software will be open and shared to users around the world to jointly realize the scientific goal of "advanced space-based solar observatory".
It is understood that the sun is the star most closely related to human beings, and it is also the only star that can be studied in detail.
It brings light and warmth to people, but also has a major impact on the planet.
The "fury" of the sun is a violent eruption again and again, including solar flares, coronal mass ejections, etc., which will cause a series of strong disturbances in the solar-terrestrial space, and even affect all aspects of human daily life.
Humans live in the solar system controlled by the star, the sun. Therefore, whether it is to explore the mysteries of stars from an astronomical perspective or from the actual production and life of human beings, it is very necessary to carry out systematic and in-depth observations of the sun.
