At 7:38 on June 4th, the Chang'e -6 rising device carried the moon sample from the back of the moon. After working for about six minutes, the 3000N engine was successfully sent to the scheduled ring -moon orbit.

Since 6:23 on June 23:23, Chang'e 6 has quickly completed a series of work such as "digging soil", "doing scientific research", "flag -raising", and "take -off"."Specialty" "will return to the earth.

"Digging"

Chang'e 6 mission is not the first time that Chinese detectors have traveled to the Antarctic Basin of the Moon Back.In 2019, the Chang'e -4 detector and the "Yutu II" lunar car successfully landed in the basin in the basin.

From June 2nd to 3rd, Chang'e 6 successfully completed the intelligent and fast sampling of the Antarctic Basin on the back of the moon, and was stored in the precious moon back sample in the predetermined form in the predetermined form.Essence

"Digging the soil" is the fine work of the door, focusing on "fast and stable".Limited to the length of the relay communication time of the back of the moon, Chang'e 6 adopts fast and intelligent sampling technology to shorten the effective working time of the moon sampling to less than 20 hours.Two methods such as diamonds and robotic arms are collected through drilling and robotic arm tables, and the moon samples are collected to achieve multi -point and diversified automatic sampling.

"Doing Scientific Research"

In the "Guanghan Palace", Chang'e 6 also "started scientific research", highlighting the "international fan".The French lunar mirror detector carried by the Chang'e 6 landing device has been turned on in the ground moon transfer, the ring moon stage and the monthly working section.Work; Italian laser horn reflex installed on the top of the lander becomes the position control point that can be used on the back of the moon.

This month's journey, Chang'e -6 is equipped with international loads with the European Air Bureau, France, Italy, and Pakistan for scientific detection.The Eukang Bureau Director Ashbarbach said that the successful landing of Chang'e 6 is a great achievement.

For Chinese and foreign scientists to explore the moon, Hu Hao, chief designer of Chang'e 6 mission, previously emphasized in an interview with China News Agency that the moon is shared by human beings. China goes to the moon to explore more unknown.For questions, more foreign friends are welcome to participate together.

"Banner"

In addition to "digging" and "doing scientific research", Chang'e -6 detectors have not forgotten a sacred "flag -raising ceremony" on the moon.After the table was completed, the five -star red flag carried by the Chang'e 6 lander was successfully launched on the back of the moon.This is the first time in China to show the national flag independently on the back of the moon.

Due to the different positions of the lunar moon, the Chang'e 6 Five -Star Red Flag display system has made adaptive improvements on the basis of Chang'e 5 mission, and conducts display effects and product life reliability assessments.

Light is important for the imaging effect of the five -star red flag. Since Chang'e -6 is landing on the back of the moon, the moonlight light and flag angle have changed.To this end, the development team proposes a variety of improved solutions to conduct multiple rounds of scheme evaluation and ground simulation moon imaging test to ensure the best imaging effect of the five -star red flag.

The temperature difference between the moon surface is large and the radiation is strong, and the five -star red flag with ordinary materials is difficult to meet the requirements.The development team and Wuhan Textile University and other units carry out the development of the Xuanwu Rock Fiber Flag Flame, and successively overcome technical problems such as fiber molding, fabric weaving, printing stains, and flag -faced and extended mechanism.environment.

"Take -off"

After successfully completing the sampling and packaging of the moon, Chang'e 6 rising device must prepare the moon surface to take off. This is a difficult subject.As we all know, the carrier rocket has a complete launching tower system on the earth. The take -off position is accurately calculated, and the flight track is calculated over and over again.

But the moon takes off is different from the ground. There is no take -off place of Ma Pingchuan, and there is no mature and complete launch tower.Chang'e -6 rising device can only use the lander as a "temporary tower."

Compared with the Moon Moon on the No. 5 of Chang'e, Chang'e -6 takes off from the back of the moon and cannot directly obtain the support of ground measurement and control. Instead, with the assistance of Lieutenant Kuangqiao No. 2 Lieutenant Star, it needs to use its own special sensitive device to achieve autonomous positioning independent positioning., Setting up, the implementation of the project is more difficult.After the Chang'e -6 rising device was taken off, three stages of vertical rise, posture adjustment and orbital shot into three stages, and successfully entered the scheduled ring -moon flight track.

Follow -up, after completing the connection with the delivery with the sample transfer and the waiting of the moon, Chang'e 6 will return to the earth with the "Guanghan Palace Treasure".
