Name after reading it! Interpretation of the scientific goals of the Advanced Space-based Solar Observatory (ASO-S)

The sun, the star most closely related to us, is the only one that can be studied in detail. It brings light and warmth to us, but also has a major impact on the planet. my country's first comprehensive solar exploration satellite, the Advanced Space-based Solar Observatory (ASO-S), to be launched in October 2022, will reveal the sun's magnetic field, solar flares and coronal mass ejections ("one magnetic and two storms"). ) formation and interrelationships.

Sun, here we come!
About 4.6 billion years ago, on the spiral arms about 26,000 light-years from the center of the Milky Way, a molecular cloud began to collapse under its own gravity and gradually formed the sun we know today.

From ancient times to the present, the sun has caused too much thinking of human beings, and we are full of curiosity about this dazzling star: why does it shine? Does it exist forever? What is its structure? What are its salient features? How will it affect the earth? In order to answer these questions, scientists have not only developed corresponding theoretical foundations, but also built or launched various detectors to unravel the mystery of the sun layer by layer.

ASO-S Science Objectives
A closer look at the sun (and not looking directly at the sun at any time, even during an eclipse) reveals that the sun is rich in phenomena, some of which are particularly striking, including:

Sunspots: The dark spots on the surface of the sun are essentially strong magnetic fields and low temperatures. As early as more than 2,000 years ago, there were records of sunspots in ancient China. In 1610, Galileo confirmed the existence of sunspots when he observed the sun with a self-made telescope. After hundreds of years of continuous observation and statistics, we can clearly see the periodic changes in the number and position of sunspots, which is the famous 11-year solar activity cycle.

Solar flare: This is an intense burst of radiation that is very bright and can last from minutes to hours. Flares are the most violent explosive events in the solar system, emitting light with wavelengths spanning the entire electromagnetic spectrum (from radio waves to gamma rays).

Coronal Mass Ejection: The sun's outer atmosphere, the corona, releases plasma and magnetic fields suddenly and violently. A giant coronal mass ejection can contain billions of tons of material that is accelerated into space at extremely high speeds, colliding with any planet or spacecraft on its journey.

Whether it's sunspots, solar flares or coronal mass ejections, their source is the sun's magnetic field. Changing solar magnetic fields can not only generate sunspots in the photosphere, but also trigger flares and coronal mass ejections. The sun's magnetic field, flares and coronal mass ejections are referred to as "one magnetic and two storms" for short, which is also the main scientific goal of the ASO-S satellite.

How does the activity of the sun affect the earth?
Although the sun is an average of 150 million kilometers away from the earth, once the sun is "powerful", the magnetic cloud generated by flares and coronal mass ejections will carry a large number of charged high-energy particles and come straight to the earth, which is closely related to the earth's environment, especially modern life. The electromagnetic environment can cause serious damage.

During Halloween in 2003, the sun was unwilling to play the role of a "trick-or-treater" and caused a mess to the earth, causing a series of scientific satellites such as GOES, ACE, SOHO and WIND in Europe and the United States to suffer varying degrees of damage. As a result, the global satellite communication is interfered, the GPS global positioning system is affected, the positioning accuracy is deviated, and some traffic systems on the ground and in space that require instant communication and positioning have been paralyzed to varying degrees. This solar event is also known as the "Halloween storm."

Given these circumstances, continuous monitoring of solar activity is necessary. It is calculated that in the event of solar flares, coronal mass ejections and other eruptive activities, scientists can obtain information at least 40 hours in advance, so as to make relevant protective measures in time to avoid damage to the human living environment.

What scientific payloads are carried on the ASO-S satellite?
The sun emits light of different wavelengths, but the earth's atmosphere is not transparent to all wavelengths. Only visible and infrared light, as well as limited ultraviolet and radio radiation, can be observed on the ground. They are in the broad solar radiation. only a small part of the spectrum. Therefore, only by launching the probe into space, avoiding the influence of the earth's atmosphere, and studying the sun from various wavelengths, can a complete picture be drawn.

The three payloads of the ASO-S satellite will be used to measure the sun's magnetic field and observe coronal mass ejections and solar flares:
After the successful launch of ASO-S, the "solar storm" of the 25th solar cycle will be recorded in detail. After the satellite is in orbit, it will generate about 500GB of detection data every day, and all scientific data and analysis software of the satellite will be open and shared for global users to jointly achieve the ASO-S scientific goals. At that time, the research around the ASO-S observations will become an international hotspot. While studying the natural law of "one magnetic and two storms", scientists will also timely predict the impact of solar eruptions on human beings, benefiting all human beings.

The ASO-S satellite naming activity of all channels is the same activity, and there is no need to participate repeatedly.
Please name ASS-S launched in October 2022 from Jiuquan, though there were Xihe(羲和) and Kuafu(夸父) named for others.

my country's first dedicated satellite for comprehensive solar exploration will be launched in October

Pinwan, July 11, according to the Chinese Academy of Sciences, the upcoming "Advanced Space-based Solar Observatory (ASO-S)" will open a Chinese nickname and name interpretation solicitation activity today. The solicitation time is 2022. July 11-24.

Relevant information shows that this space science satellite was deployed and developed by the Space Science (Phase II) pilot project of the Chinese Academy of Sciences. It will be launched at the Jiuquan Satellite Launch Center in October 2022 to start a journey of exploration of the sun.

The advanced space-based solar observatory weighs 888KG and operates in a sun-synchronous orbit of 720KM. It has an all-solar vector magnetic imager, a Lyman Alpha solar telescope, and a solar hard X-ray imager. It is equipped with 3 payloads and has a design life of more than 4 years. For more than 5 years, it is China's first comprehensive solar exploration dedicated satellite independently proposed by Chinese heliophysicists.

According to reports, taking advantage of the opportunity of the peak year of the 25th week of solar activity, the Advanced Space-Based Solar Observatory will conduct simultaneous observations of the two most violent eruptions on the sun - solar flares and coronal mass ejections, as well as the full-solar vector magnetic field. "One Magnetic Two Storms", the origin, interaction and correlation of the Sun's magnetic field, solar flares and coronal mass ejections, also underpins severe space weather forecasting.
ASO-S might be launched in October from Jiuquan.

Launch time of 23:40 UTC corresponds to LTDN of 06:00, a reasonable choice for both ASO-S and a radar satellite.
A published LTDN for ASO-S is indeed 06:00, with the constant view of sun except for eclipses in summer in the southernmost part of the orbit.

Quote
The satellite will go through the shadow of the Earth between middle May and August with a maximum eclipse time of 18 minutes.
