What is Chang e 2 s space mission? When will China land a man on the moon?

Chang'e-2 is the pilot satellite of the second phase of China's lunar exploration program, and one of its important tasks is to carry out high-precision imaging of the landing area of Chang'e-3, so its flight altitude around the moon will be reduced from 200 kilometers to 100 kilometers during Chang'e-1. The accuracy of the Chang'e-2 CCD camera will also be increased from 120 meters to less than 10 meters. [1] Considering the large number of key technologies to be overcome in the second phase of the lunar exploration project, the technical span and the difficulty of implementation, the State Administration of Science, Technology and Industry for National Defense decided to transform the backup satellite of Chang'e-1 into the pilot satellite of the second phase of the lunar exploration project, Chang'e-2, aiming to test and verify some key technologies of the Chang'e-3 mission, accumulate experience for the Chang'e-3 and Chang'e-4 probes to achieve a soft landing on the lunar surface, and deepen lunar scientific exploration.

At 18:59:57 on October 1, 2010, the Chang'e-2 satellite will be launched from the Xichang Launch Center. [2] Origin: China's second artificial satellite around the moon.

It is based on the Chang'e-1 backup satellite of the first phase of the lunar exploration project for technical improvement, as the pilot star of the second phase of the project, named Chang'e-2. Purpose: It is used to test and verify some new technologies and equipment, reduce the risk of future projects, and deepen the scientific exploration of the moon.

Main tasks: to obtain clearer and more detailed lunar surface image data and lunar polar surface surface data;

Main purpose: To carry out some key technical tests for the soft landing of the moon of the Chang'e-3 mission, and to carry out high-precision imaging of the Chang'e-3 landing area.

Technological breakthrough: orbit entry time cut in half; The detour height is reduced by half; The radio transmission frequency is higher; 5 times higher laser emission frequency; 17 times higher camera resolution; The transfer rate is increased by 1 times. [3] Important parameters of Chang'e-2 - Chang'e-2 weighs 2,480 kg;

With a total length of 54 84 meters, a take-off mass of 345 tons, and a carrying capacity of 3 8 tons, the Chang'e-2 launch vehicle will be the 131st flight of the Long March series of rockets.

The rocket sent Chang'e-2 into a direct lunar orbit with an apogee altitude of nearly 380,000 kilometers, while the apogee altitude of Chang'e-1 was only about 5,100 kilometers.

Due to the different orbit design, Chang'e-2 can reach the moon in about 5 days (120 hours), which is much shorter than the 12-day lunar journey of Chang'e-1.

The satellite orbits the moon at an altitude of 100 kilometers, which is 100 kilometers closer to the moon than Chang'e-1;

The newly developed camera on the satellite can increase the resolution of images taken from Chang'e-1 from 120 meters to about 10 meters.

The design life of Chang'e-2 is half a year, and the design life of Chang'e-1 is one year, and the actual life is 494 days, of which 482 days are around the moon.

There are more than 80,000 components in rocket systems and satellite systems, and more than 200 pyrotechnics are ignited and detonated in the air.

The total cost of the Chang'e-2 mission is about 900 million yuan.

Chang'e-5 successfully landed on the moon at 23:11 on December 1, 2020, and the Chang'e-5 probe successfully landed in the pre-selected landing area near the west longitude and north latitude of the moon's front side, and sent back landing images.

The landing process of Chang'e-5 on the moon has undergone active deceleration, rapid adjustment, approach, hovering and obstacle avoidance, slow descent and free fall.

The Chang'e-5 mission is the sixth mission of the "Lunar Exploration Project" and one of the most complex and difficult missions in China's aerospace industry to date.

At 23:11 on December 1, 2020, the Chang'e-5 probe successfully landed on the moon after a week-long journey of Earth-Moon transfer, near-moon braking, and circumlunar flight.

At this time, a set of historical images were transmitted back from outer space, and the whole country of China was boiling, and the world was shocked. The Chang'e-5 probe successfully "landed" on the moon, leaving once again the mark of the Chinese on the pre-selected landing area on the front of the moon.

The success of Chang'e-5 is inseparable from the unremitting dedication and efforts of the vast number of aerospace engineering workers, who have solved one historical problem after another in their ordinary and unusual scientific and technological work, and finally become the legend of Chang'e-5 that is boiling all over the world today.

At 4:30 a.m. Beijing time on November 24, the Long March 5 Yao-5 carrier rocket was ignited at the Wenchang Space Launch Site in China, and after about 2,200 seconds of rocket flight, the Chang'e-5 probe was successfully sent into the scheduled orbit, opening China's first exoterrestrial object sample return journey.

Chang'e-5 will land in the northern region of the Lunar Storm Ocean as planned, collect lunar soil and lunar rock samples and return them to Earth, and then carry out systematic and long-term laboratory analysis and research to analyze the structure, physical properties and material composition of lunar soil, and deepen the study of the origin and evolution history of the Moon. This will be the first lunar surface sample in 44 years that humans have brought back from a distant moon.

After arriving on the Moon, Chang'e-5 will spend two days collecting lunar soil and then returning to Earth, a mission that will take about 23 days. Eventually, the Chang'e-5 lander will land in Siziwangqi in Inner Mongolia, northern China.

At 4:30 on November 24, 2020, at the Wenchang Cosmodrome in China, the Chang'e-5 probe of the lunar exploration project was successfully launched by the Long March 5 Yao-5 carrier rocket.

The Chang'e-5 probe is composed of four parts: orbiter, returner, lander and ascent, after the Earth-Moon transfer, near-moon braking, and circumlunar flight, the lander and ascender combination will be separated from the orbiter and returner combination, the orbiter will carry the returner to stay in orbit, and the lander will carry the ascender to carry out a soft landing in the pre-selected area of the lunar front, and carry out follow-up work such as automatic sampling of the lunar surface as planned.

Chang'e-5 successfully landed on the moon, what is this mission, and when is the return time?

The mission of Chang'e-5 to the moon is mainly to collect lunar soil and study the history of lunar evolution, as well as test automatic sampling and packaging, lunar surface take-off and lunar orbit docking, etc.

Chang'e-5 successfully landed, and the process of Chang'e-5's landing on the moon was that the rocket took them to the earth, and then transferred from the earth to the moon, collected on the moon, and then returned to the earth, and the task was to go to the moon to collect soil.

The Chang'e-5 ascender 3000N engine worked for about 6 minutes and successfully sent the sample-carrying ascender into the predetermined orbit around the moon. This is the first time that an extraterrestrial object has taken off in China. It is another achievement in the history of aerospace and is of great significance.

Chang'e-5 will collect about 2 kilograms of lunar soil from the moon, seal it and return the lunar samples to Earth through lunar takeoff, lunar orbit rendezvous and docking, moon-to-earth transfer and re-entry**.

The Long March 5 Yao-5 carrier rocket was used to send the probe into a predetermined orbit, and after completing several orbit corrections, it landed smoothly, and the task was to bring the soil on the surface of the moon back to the earth for study, and the second was to realize the automatic sample return of extraterrestrial objects.

Chang'e-5 landed on the moon on December 1.

The Chang'e-5 mission is to collect dust and debris in unexplored areas of the moon's front and return them to Earth to facilitate the analysis of the moon's evolutionary history.

The Chang'e-5 sample could fill an important gap in scientists' understanding of the moon's volcanic activity. This material from the Moon could also help researchers identify Earth, Mars and Mercury more precisely.

and other ages on the surface of the planet. According to the method of calculating craters, the Moon is also an important reference for dating other planets.

The four daily missions have been approved by China and are being carried out smoothly at this stage.

According to the report, the fourth phase of China's lunar exploration program includes Chang'e-6.

The daily missions of Chang'e-7 and Fairy 8 will also be carried out in succession within ten years. Among them, Chang'e-6 is Chang'e-5.

The backup data, which has the effect of sampling back, will go to the moon.

Reverse out of the task.

Liu Jizhong announced that the production and manufacturing of Chang'e-6 products have basically been completed, and Chang'e-4 has been integrated.

The first time to the back of the moon, through the pre-technical engineer.

The expert discussion is also fully considered to consider the reverse sampling of the moon back. In fact, since Chang'e-5 collected lunar soil on the front face of the moon, scientific research results on lunar soil have been announced in China.

The latest developments show that Chinese experts have isolated a small single crystal particle with a size of about 10 m around it from 140,000 lunar samples, and successfully interpreted its molecular structure and identified it as a new mineral. This mineral is the sixth new mineral we have found on the moon and is known as the "fairy stone".

Liu Jizhong showed that compared with the "lunar soil" collected by Chang'e-5 on the front face of the moon, the sample returned from the back of the moon is more valuable. Regarding the return of sampling on the back of the moon, Hu Hao, the chief designer of the third phase of China's lunar exploration project, previously replied to the news ** that compared with Chang'e-5, Chang'e-6 encountered communication difficulties in the daily mission. It is difficult to realize electromagnetic waves on the opposite side of the moon.

Relay satellites are needed for transmission, which means that data communication has to "turn a corner" to reach the earth.

For Chang'e-6, Hu Hao emphasized that in the past ten years of research and development, China's electronic components have developed rapidly, and the replacement effect of imported components is significant. Although Chang'e-6 is the backup data of Chang'e-5 and has become a commodity, the current situation shows that localization has been further improved.

For Chang'e-7, Liu Jizhong introduced in detail that Chang'e-7 has been developed, and the south pole of the moon will be tested later, and the standard type of the international lunar scientific research station will also be created.

The Chang'e-6 mission is to complete the lunar polar region sample return mission. Strive to collect one kilogram to two kilograms of Kai noise samples from the collection area and return to the earth, which is expected to be manned to the moon in 2024.

Among them, Chang'e-6 is a backup of Chang'e-5, which has the function of sampling and returning, and will go to the far side of the moon to carry out missions. I think in the near future, Kai Lang will soon be able to land people on the moon.

Chang'e 6 is to collect Chang'e stones, and it is also to see if there is any water in it, which is estimated to wait until 2023.

The Chang'e-3 satellite is the second phase of the Chang'e project of the China National Space Administration, which is composed of a lander and a rover (i.e., the "Yutu", a lunar rover) to carry out the first soft landing on the moon and an automatic patrol survey, obtain the material composition of the moon and analyze it, and extend the "surface exploration" of the first phase of the project to the internal exploration. [1] The Chang'e-3 spacecraft will cruise on the lunar surface for 90 days, covering an area of up to 5 square kilometers, and will capture lunar soil for analysis in the vehicle, and the data obtained will be directly transmitted back to Earth. [2] On August 28, 2013, China's State Administration of Science, Technology and Industry for National Defense announced that the leading group for major projects of the lunar exploration project held its 11th meeting and mobilization meeting for the Chang'e-3 mission on the same day, and deliberated and approved the Chang'e-3 mission from the development and construction stage to the launch and implementation stage.

The Chang'e-3 probe was launched at 1:30 a.m. on December 2, 2013 at the Xichang Satellite Launch Center in Sichuan Province. According to ** TV station, the "Chang'e-3" probe will be launched at 1:30 on December 2 at the Xichang Satellite Launch Center.

Chang'e-3 will carry the Yutu lunar rover to achieve a soft landing on the moon and a lunar surface survey for the first time, and carry out scientific explorations such as lunar surface morphology and geological structure surveys. On September 11, 2013, Chang'e-3 was transferred by plane and arrived at the Xichang launch site at 10 o'clock on the 12th. Chang'e-3 was launched from the Xichang Satellite Launch Center by a Long March-3B carrier rocket at 1:30 a.m. on December 2.

It will carry China's first lunar rover and achieve China's first soft landing on the moon. On November 26, 2013, the rover was officially named Yutu.

Chang'e-3 was launched from the Xichang Satellite Launch Center by a Long March-3B carrier rocket at 1:30 a.m. on December 2.
