"China Reunion" settled in Chongqing!How much use is it?Or master the lifeblood of the life of the earth

Data show that the observation diameter of the earth has reached 93 billion light years. Both the unit and the numbers highlight the wide range of the universe. In this huge range, countless mysteries have been hidden, which has attracted human exploration. Technical problems, we still have not knowing much about the universe, and it can even be said to be a drop in the sea.

In recent years, my country has also achieved great achievements in the aerospace field. According to the recent news of Chongqing, Beijing Institute of Technology and Chongqing have signed a comprehensive strategic agreement to jointly develop deep -space detection radar "China Compound Eyes". The scope of observation is expected to reach 150 million kilometers, becoming the most detected radar in the world. How big is the role?

"Settling" in Chongqing's "China Reunion".

A large pot, a large antenna, maybe this is the deepest impression of "China Eye", and the simplest description. From this, you can imagine the "China Reunion".

The word is like its name. The construction distributed radar of "China Reunion" consists of more than 20 small antennas. The caliber of each antenna is between 25 meters and 30 meters, and it is arranged like insects. It is also the origin of the name of "China Reunion".

The completion of Guizhou's "China Sky Eye" has filled the gaps in the field of observing outer space in my country, and played a huge role in the field of space detection. But why do you still have to build "China Eye" and "China Eye"?

In response to this issue, academicians of Beijing University of Science and Technology explained that "China Reunion" and "China Eye" radio telescope is very different, because the asteroid itself cannot emit electromagnetic waves. Seeing small asteroids that do not launch electromagnetic waves in the universe, we need to actively launch electromagnetic waves to observe asteroids.

The "Chinese Eye Eye" is observed through its own transmission of electromagnetic waves and receiving back waves. It belongs to a active observation equipment, which can complement the passive observation "China Eye".

It is understood that the construction of the "China Reunion" project is divided into three phases. First of all, the first phase is used to verify the feasibility of the radar system and key core technologies. The contracting contract, the location of Chongqing Yunyang, is mainly used for asteroid detection, and completes the detection and imaging demonstration verification of deep space radars. All aspects of the period will be greatly improved.

Finally, it is the question of why Chongqing is selected. This is mainly because the latitude of Chongqing is more suitable for the setting and observation of radar. Especially in the future, the third phase will be built. It will become the first radar with three -dimensional imaging in the world, and my country will also have greater right to speak in this field.

The asteroid detector- "China Reunion".

It is reported that the "China Reunion Eye" project can observe a celestial body within 150 million kilometers of the earth, becoming the most detected radar in the world, especially the observation of small asteroids in this range, which can facilitate us to stare at these small stars. But why do you pay attention to these asteroids so much?

This is because there are a large number of small asteroids in the solar system. According to the data, there are already 1.2 million asteroids discovered alone, of which more than 25,000 have a serious threat to the earth. The greater the danger. For example, the once -dinosaur extinction incident was related to the impact of the asteroid.

However, because the number of asteroids is too much, the trajectory is unstable, it is not easy to find. It is difficult for our current technology to fully monitor the asteroid. A hot spot for research.

The construction of "China Reunion" provides important strategic support for the asteroid defense and its scientific research, which is used for research on various celestial bodies, looking for small asteroids that are dangerous to the earth, observing its size, sports trajectory, etc. We make preparations in advance and try to avoid the Earth's impact on the asteroid. In addition, it also plays an important role in the outcomes of astronomical 2 in the future.

All in all, we need such a large radar to observe small asteroids and regional space areas on the support of human future exploration and major national strategies.

However, from the scope of observation, many people think that "China Refuse Eye" is very weak compared to "Chinese Eyes". In fact, this view is wrong. The role of "China Reunion" is still very large!

Do not think that after the construction of "China Reunion" and put it into operation, the "China Eye" is useless, and it is backward. It can only be said that the division of labor between the two is different. First, they can all provide convenience to explore the universe in China and contribute to Chinese space exploration.
