Experts interpret the Kuafu 1 satellite What are the scientific objectives of Kuafu 1 ?

The scientific objectives of Kuafu-1 can be summarized as "one magnetic field and two storms", namely the solar magnetic field, solar flares and coronal mass ejections. The study of them can reveal their formation, evolution, interactions, and possible causal relationships. In short, they can protect humanity from space disasters in fields such as spaceflight, communications, etc.

In particular, every 11 years, the sun will enter the peak period of activity, and the phenomenon of "two storms" is more obvious. It can be simply understood that the sun has released huge electromagnetic interference on the earth, satellites, communications, power grids, etc. will be significantly affected.

Musk's "Starlink" satellites suffered this disaster, and as many as 40 satellites were scrapped.

The next peak will be between 2024 and 2025, when Kwafu 1, which has a design life of four years, will participate in the mission to document the "solar storm" in detail.

Because solar activity has a great impact on satellites, the "Parker", a solar exploration satellite developed by the United States as the first in history to fly close to the sun, can only be observed sideways. Can our "Kuafu-1" withstand high pressure?

Zhu Cheng, chief designer of the "Kuafu-1" satellite system, said that the satellite is equipped with seven optical devices and is precisely pointed at the sun, which means that "Kuafu-1" will overcome the problem of "frontal observation" that even the United States has not yet achieved.

In addition, frontal observation requires a very high degree of consistency of optical axes between devices, and it is difficult to imagine that mechanical factors at launch, temperature changes in space, and ultra-high vacuum environments must also be considered.

Gan Weiqun said: The "Kuafu-1" is a space science satellite specially proposed for solar observation, which is completely guided by scientific objectives and will strive to achieve a breakthrough by leaps and bounds in China's space-based solar exploration satellites.

Finally, I warmly congratulate China on the complete and successful launch of "Kuafu-1"."The country's heavyweight satellite! This is another great feat of China's high-level self-reliance and self-improvement in the development of space science, which demonstrates the continuous expansion of the boundaries of space exploration of the Chinese nation"The exploration capability continues to increase, moving to an unprecedented new height, and is gradually becoming a space power that cannot be ignored in the 21st century!

The core scientific goal of Kuafu-1 is to continuously observe and track the whole process of solar eruptions and provide support for high-tech space disaster weather forecasting.

It can improve my scientific and technological capabilities, and it can make my satellites run better, and it can also improve my international influence, and it can also let other countries see my country's performance.

The first point is of greatest significance, such a launch also shows that our satellite has a new starting point, and the second point is that the entire satellite Luqing will have a new space for development.

The successful launch of this Yunluo indicates the further development of China's science and technology, which can enhance China's voice in the international arena and further enhance China's scientific and technological strength.

It will be conducive to providing support for space severe weather forecasting that affects high-tech activities such as human spaceflight, communications, and navigation.

It can improve my scientific and technological capabilities, and it can bridge the gap to make my satellites search and defeat better operation, and it can also improve my international influence, and it can also let other countries see my country's performance.

This launch has also been further improved in China's space field, and it also interprets the wisdom of the Chinese people.

China's latest achievements in the field of aerospace include the successful first flight of the Long March 5B carrier rocket, the first flight of the Long March 8 launch vehicle, the successful high-speed re-entry flight test of the new-generation manned spacecraft test ship, the completion of the world's first unmanned rendezvous and docking in lunar orbit by Chang'e-5, the Tianwen-1 Mars exploration mission, the first step of China's planetary exploration, the completion and opening of the Beidou-3 global satellite navigation system six months ahead of schedule, the start of the construction of the flux broadband satellite system, and the major special project of the high-resolution earth observation system. On April 29, 2021, the Tianhe nuclear module of China's space station was successfully launched. Subsequently, it docked with the Tian and Shen and No. 3 cargo spacecraft, and the Shen and No. 3 spacecraft, with a total of six astronauts stationed in succession, marking China's official entry into the space station era.

Satellite orbital propulsion technology is applied.

Generally speaking, Kuafu-1 is a solar detection satellite, compared with the state scattered earth satellite, digging guess has the difficulty of launching, propulsion, signal reception and other problems, but these difficulties have been overcome by Chinese scientists one by one, to achieve a technological breakthrough. Specifically, these technologies are applied: power propulsion technology, remote sensing reception technology, launch vehicle technology.

The following author will explain these contents in detail.

Clause. 1. China's solar exploration satellite Kuafu-1 was successfully launched, and power propulsion technology was applied: because it is different from the earth's suborbital satellite, Kuafu-1 is a solar exploration satellite, so it cannot be directly sent to the orbit around the sun.

Therefore, after the launch vehicle sends Kuafu-1 to space, Kuafu-1 will use its own power system to propel itself into orbit around the sun, and there are two parts of the Kuafu-1 power system, one is the propellant power system, and when the propellant is exhausted, there is also the solar power system, which can be propelled to the predetermined orbit by using these two parts. Therefore, the successful launch of Kuafu-1 applied power propulsion technology.

Clause. 2. China's solar detection satellite Kuafu-1 was successfully launched, and remote sensing reception technology was applied: Because unlike the earth's suborbital satellite, which is close to the ground command center, Kuafu-1 has completely penetrated into space and is far away from the ground command center.

Therefore, it is not possible to transmit the signal directly. Therefore, Kuafu-1 uses remote sensing technology to transmit the signal to the Earth signal satellite first, and then the signal satellite transmits it back to the earth. This process is known as remote sensing reception technology.

Clause. 3. China's solar detection satellite Kuafu-1 was successfully launched, and carrier rocket technology was applied: Because Kuafu-1 is a solar exploration satellite, it will be sent to space far away from the earth.

Therefore, this time the launch vehicle has been updated with a more powerful power plant. This will ensure that Kuafu-1 will be sent as far away from Earth as possible to enter orbit. Therefore, Kuafu-1 was successfully launched, and launch vehicle technology was applied.

Both apply artificial nuclear power technology and power generation technology, as well as navigation technology and robotic arm technology, which are some new technologies.

At 7:43 a.m. on October 9, 2022, China's comprehensive solar exploration satellite "Kuafu-1" was successfully launched. On August 4, 2006, the "News Focus" column of the American magazine "Science" quickly reported on the situation related to China's "Kuafu Plan".

The United States, Russia, and the United Kingdom have all launched detection satellites, and they have also made great achievements, and they are all constantly improving and improving, and have a certain impact.

The countries he mentioned are the United States, Japan, the United Kingdom, Russia, and so on, and the comprehensive strength of these countries is still very strong.

The implication is that I hope that this satellite can always stick to the universe and have a lofty love and pursuit for the sun.

The main reason for naming Kuafu No. 1 is that it is a kind of romance that belongs exclusively to the Chinese, which means that the Chinese chase the sun like Kuafu.

This is based on the myth of "Kuafu chasing the sun", which can represent our spirit of exploration of the sun in the universe.
