The most direct way to express the thoughts of the motherland China- People’s Republic of China is stunning photography Everyone appreciates the earth home from different angles. Guess which “magic camera” these photos correspond to? #chasing the 14th star of Shenzhou ……
It weighs more than 6,000 tons and covers an area as large as 23 basketball courts! Xinjiang Uygur Autonomous Region, China- People’s Republic begins construction of world’s largest mobile radio telescope….
Speaking of radio telescopes, we all think of “China Sky Eye”. This sky-viewing artifact located in the Dawodang depression of Pingtang County, Guizhou Province has a diameter of 500 meters. The full name is “500-meter Aperture Spherical Radio Telescope (FAST)” ”, its spherical observation area is 250,000 square meters, comparable to 30 standard football fields, far ahead of other radio telescopes in the world, but this radio stabilization is fixed, and its sky survey observation function relies on the rotation of the earth , it cannot directionally observe celestial objects at a certain position in the sky, so its observation function has certain limitations. Its sky survey observation function is unparalleled, but its directional observation function is very weak. Only the celestial body directly above it can be in its best position.
Compared to the “China Sky Eye” 110-meter large-aperture radio astronomical telescope project started in Xinjiang] On September 21, 2022, an event of great significance to my country’s astronomical field occurred in Shihezi Village, Banjiegou Town, Qitai County, Changji Hui Autonomous Prefecture, Xinjiang. ——The foundation stone of the 110-meter-aperture omnidirectional movable radio telescope project was laid here.
Observation location. Chinese Sky Eye So, in addition to this fixed spherical radio telescope, the more common is the omnidirectional movable spherical radio telescope. This kind of telescope can adjust the observation direction and position at will. Except for the part blocked by the earth, it is almost unobserved….. The limitation of the position of celestial bodies, which is crucial for observing those celestial bodies that need to be studied for a long time.
So which is the largest mobile radio telescope in the world? The current name belongs to the Green Bank Radio Astronomy Telescope in the United States. It is located at the Green Bank Observatory in West Virginia, United States. This telescope is about 146 meters high, equivalent to the height of 49 floors, and weighs 7,700 tons. It is larger than the metal frame of the Eiffel Tower. (about 7,300 tons) is still heavy, equivalent to the weight of a medium and large destroyer, and it is also the largest land-based movable structure in the world. Green Bank Radio Telescope
What is more special is that the active surface of the dish antenna is not a perfect circle, but an ellipse with a length of 110 meters and a width of 100 meters. It is also the omnidirectional movable radio telescope with the strongest observation ability in the world.
However, according to a report by “CCTV News” on September 21, the world’s largest omnidirectional movable radio telescope is being built in Qitai County, Xinjiang, my country. The English QiTai radio Telescope, abbreviated as QTT) “has broken ground and started construction. It is a circular spherical radio telescope with a diameter of 110 meters, which is slightly larger than the Green Bank radio telescope in the United States.
Structural simulation diagram of odd radio telescope Qitai Radio Telescope is built in the closed basin of Shihezi Pasture, Shihezi Village, Banjiegou Town, Qitai County, Xinjiang. It has a high altitude, a relatively dry climate, and is far away from densely populated towns. It is shielded by mountains and has good astronomical observations. condition.
The scale of this giant sky-watching artifacts is also very large. It is expected that its antenna will exceed the height of a 35-story building, its weight will reach more than 6,000 tons, and its spherical aperture area is equivalent to 23 basketball courts. It can achieve high quality from 150MHz to 115GHz. During the observation, the surface shape accuracy can reach 0.3 mm and the pointing accuracy is 2.5 arc seconds, which can observe the celestial bodies with very dim wireless signals in the distant universe with high precision. Its observation objects include black holes, quasars, fast radio bursts, dark matter, gravitational waves, and even alien civilization signals.
It is estimated that the construction of this telescope will take 6 years. The media said that it will become the world’s largest and most accurate 100-meter omnidirectional movable radio telescope after completion. It will not last too long, because an omnidirectional movable radio telescope with a diameter of 120 meters, the Jingdong 120m Pulsar Radio Telescope (JRT), is being built in the Wuliang Mountains in Dali, Yunnan, my country. The giant telescope is located in Xujiaba, Taizhong Town, Jingdong County, Pu’er City, Yunnan Province. It is the largest omnidirectional movable radio telescope currently under construction in the world. Jingdong 120m Pulsar Radio Telescope
I believe that with the use of these astronomical observation “power tools” with the title of “world first”, our achievements in astronomical exploration will gradually become world first.

More than One year ago on 24th November 2020, the Chang Zheng – Long March Five Carrier Rocket Launched away in CNSA – China National Space Administration China Wenchang spaceport launch, Change Five Lunar probe into orbit, opened up towards China – People’s Republic of China’s first celestial bodies sample return trip from Mons Rumker on the Lunar Surface of the moon New research achievements – Chinese scientists reveal the composition of lunar soil minerals and space wind at the landing site of Chang’e 5
Chinese scientists discover new minerals on the moon for the first time The autumn 9th September 2022 today, on the eve of the traditional Chinese festival Mid-Autumn Festival, in which duration on the 10th towards 13th September 2022 the CNSA- China National Space Administration and the National Atomic Energy Agency jointly released the latest scientific achievements of Chang’e-5. Dong Baotong, deputy director of the National Atomic Energy Agency, announced at the launch event that the new mineral discovered by Chinese scientists on the moon for the first time was named “Chang’e Stone”. This is a major scientific achievement my country has made in the field of space science, and it is also a successful exploration of cross-industry and cross-professional cooperation between nuclear and aerospace.
▲The position of Chang’e stone in the sample
“Chang’e stone” is a phosphate mineral in the form of columnar crystals found in lunar basalt grains. The innovative team of CNNC Beijing Institute of Geology, through a series of high-tech means such as X-ray diffraction, isolated a single crystal particle with a particle size of about 10 microns from 140,000 lunar sample particles, and successfully deciphered it. its crystal structure. Confirmed as a new mineral by voting by the International Mineralogical Society (IMA) New Mineral Classification and Nomenclature Committee (CNMNC). This mineral is the sixth new mineral discovered by humans on the moon, and my country has become the third country in the world to discover new minerals on the moon after the United States and Russia.

On December 17, 2020, Chang’e 5 returned to Earth with 1,731 grams of lunar samples. The National Space Administration has completed the distribution of 152 lunar samples in four batches totaling 53,625.7 mg, and 98 applicants from 33 scientific research units have passed the application. The fifth batch of lunar samples is being reviewed and will be released according to procedures. The Chinese Academy of Sciences, the Ministry of Education, the Ministry of Natural Resources, China National Nuclear Corporation and other units have been approved to undertake lunar sample research work, and foreign scientists and students have also participated in the joint research. At present, the latest achievements have been made in magma differentiation, space weathering, helium-3 gas and bioenergy conversion, etc., which are useful for understanding the origin and evolution of the moon, exploring the effective use of lunar resources, and realizing “zero energy” extraterrestrial environment and life. The support system has important implications
▲Chang’e Stone Structure The National Space Administration and the National Atomic Energy Agency, as the competent government departments in China’s aerospace and nuclear fields, have always adhered to the principles of “innovative leadership, collaborative efficiency, peaceful development, cooperation and sharing”, adhering to the concept of peaceful use of space and peaceful use of nuclear energy , continue to be committed to the integration of aerospace technology and nuclear technology, continue to explore scientific frontiers in deep space exploration and nuclear technology applications, and make new contributions to promoting the development of science and technology, the emergence of scientific achievements and international cooperation. .
