Praise the 70-year-old Chang 'e IV for finishing the tenth day of work?

Chang 'e IV is the first probe in the world to land on the back of the moon. Chang 'e IV successfully landed on the back of the moon on 20 1913 October. It's only the tenth day, which has exceeded the design life. So let's rely on constellation knowledge to reveal the specific situation! Let's have a look!

Praise for 70 years, Chang 'e IV completed the tenth day's work. According to the official WeChat message of China's lunar exploration project, the Chang 'e-4 lander completed its scientific exploration work on the tenth day and entered the tenth night at1October 5 19: 30. /kloc-During the daytime work in October/October, the lander works normally and the energy is balanced. The payload lunar neutron and radiation dose detector and low-frequency radio spectrometer carried out effective detection work as planned, and the scientific detection data received on the ground were normal.

"Yutu II" patrol completed the moonlit setting on1October 5 15: 43, and entered the dormant state. /kloc-In one day in October, the patrol moved according to the overall plan, and now it has accumulated 289.769 meters. During the movement of the lunar rover, the launch detection of the lunar rover's infrared spectrometer, panorama camera, neutral atom detector, lunar radar and other payloads was organized and implemented as planned, and further scientific research data on the back of the moon were obtained. The data received on the ground is normal.

Around the National Day, Chang 'e-4 lander and Yutu-2 patrol broke through ten too cloudy working cycles, far exceeding the design life, and presented gifts to the 70th birthday of the motherland with excellent scientific exploration tasks. At present, the ground research team is processing and analyzing the first-hand detection data obtained from various scientific loads, and conducting in-depth research on the basis of the obtained scientific research results.

Praise for 70 years from Dongfanghong No.1 to Chang 'e No.41970 At 20: 29 on April 25, Dongfanghong No.1 flew over Beijing, and the whole city was crowded. This is the crowd who likes to watch satellites fly overhead.

1957, 10 year 10. On October 4th, the Soviet Union took the lead in launching the world's first artificial earth satellite, Companion-1. 1958 65438+1October 3 1 day, the United States successfully launched the Explorer I satellite. At this time, the basic socialist system has been established in China, and the people of China are enthusiastically building a new China. Considering the country's long-term development strategy, the party has decided to develop the aerospace industry. 1958, the Second Plenary Session of the Eighth Central Committee of the Communist Party of China proposed that "we should also build satellites".

In 1958, the satellite was listed as the first mission of the Chinese Academy of Sciences, codenamed "58 1", with Qian Xuesen as the team leader. In June 5438+10, eight research groups were formed by the personnel from 58 1 group, forming the research entities of satellite ensemble, rocket sounding ensemble and space exploration subsystem.

The foundation of science and technology industry is weak, resources are scarce, and without foreign aid, the road to satellite development is very difficult. 1964 Dongfeng-2 missile and atomic bomb succeeded one after another. This year, once the large-scale revolutionary music and dance epic "Dongfanghong" was staged, it became a classic that inspired the people of China to unite and forge ahead. The melody of Dongfanghong is a household name.

On August 2 of the following year, the CPC Central Committee made a comprehensive deployment of artificial satellites. From 65438+ 10 to 165438+ 10, the Chinese Academy of Sciences hosted a scheme demonstration meeting, which lasted for 42 days, and finally agreed that the satellite should "be able to get up, grasp, see and listen". Some experts suggested that the first satellite was called "Dongfanghong-1", which was unanimously recognized.

The so-called "get up and go" means that the launch is successful, and "catch up" means that the track is accurate, which is the minimum requirement. It is more difficult to "see" and "listen".

"Visible" means that you can see it with the naked eye on the earth. The diameter of the satellite is only 1 m, and the surface is not bright enough to be seen on the earth. After repeated experiments, the researchers came up with the method of "showing the stars with arrows", wrapping the third-stage rocket with "observation balls" and aluminizing the surface. After entering the orbit, the diameter of the "observation ball" is more than 3 meters, which is close to the observable brightness of the second-class star under the sunlight.

"Audible" refers to the signal sent by the satellite, which can be heard by the radio on the earth. If it is a ticking engineering signal, the people don't understand what it is, so they decide to play the music of Dongfanghong. After many experiments, the complex tones generated by electronic circuits simulate the rhythm of Beijing railway station bells and the sound of aluminum piano, and the effect is clear and pleasing to the ear.

1970 at 2 1 35 on April 24th, the Long March-1 rocket carried Dongfanghong-1 into the sky. Soon, the music of "Dongfanghong" sounded in the vast space. Through broadcasting, people all over the country can hear it. At 20: 29 the next day, Dongfanghong No.1 flew over Beijing, and the whole city was crowded. A pair of eyes, closely following this hard-won "star".

As high as the satellite can fly, China people can hold their heads high. The aerospace industry bears national self-confidence and national dignity. What other countries can do, so can socialist new China.

19711kloc-0/On October 25th, the United Nations resumed People's Republic of China (PRC)'s legal seat. "If China had no atomic bombs, hydrogen bombs and satellites since the 1960s, China would not be a big country with important influence, nor would it have such an international status."

The year Dongfanghong-1 was launched, China launched the first manned spacecraft program. Manned space flight is not only a direct manifestation of a country's comprehensive strength, but also has important strategic significance in politics, military affairs and economy.

1993, China Manned Space Engineering Office collected the name of the spacecraft, and "Shenzhou" was selected, which not only symbolizes the boat of Tianhe, but also homophones with "Shenzhou". Up to now, 1 1 astronauts have traveled in space in China and all of them have returned safely.

From astronauts flying in the sky and walking in space, to launching the Heavenly Palace, rendezvous and docking in space, and then to "knocking on" the door of the space station on Tianzhou-1, glory belongs to every participant and witness. According to incomplete statistics, there are more than 1 10 units directly involved in manned spaceflight projects, with more than 3,000 participating units and more than 654.38+10,000 engineers and technicians.

Launching artificial earth satellite, manned space flight and deep space exploration are the trilogy of space activities. The Goddess Chang'e flying to the moon's dream has come true step by step with the relay from generation to generation.

In 2004, the CPC Central Committee officially approved the report of the lunar exploration project, and the project plan was "winding, falling and returning" in three phases. On June 5, 2007, Chang 'e-1 successfully braked for the first time in recent months. In February 2008, the second phase of the lunar exploration project with the goal of "falling" was formally established. 20 10 10, Chang' e-2 satellite tested a new lunar orbit; 20 13 12, the Chang' e-3 probe landed on the moon; 20 19 65438+ 10/0/5, Chang 'e IV released photos, and the cotton seeds it carried have sprouted.
