Chang 'e V went home! What did Chang's May ball sampling trip experience?

Event review: On June 5438+February 17 1: 59, the Chang 'e-5 returner landed safely in the scheduled area of Siziwangqi, Inner Mongolia, and the mission of the lunar exploration project Chang 'e-5 was a complete success. In one mission, the Chang 'e-5 probe has continuously achieved the first major breakthroughs in China's space history, such as lunar sampling, lunar take-off, lunar orbit rendezvous and docking, and sample return. It is a lunar exploration project in China. Around, below, behind? The three-step development plan came to a successful conclusion. Chang 'e went home on the fifth, was greeted by small animals, and was warm all over the baby? Before the live broadcast, it was said that this was because there was still propellant left in the return cabin, and I was worried that I wouldn't go out after freezing, so I put on a warm baby to keep warm temporarily. ?

What did Chang's May ball sampling trip experience? The first is the preparation stage from 2004 to 20 19. On 20 1 1 and 1 year, the State Council officially approved the establishment of the third phase of the lunar exploration project, and the development of Chang 'e-5 probe started. 20 12- 12 completes the summary and evaluation stage of the detector system scheme, and shifts to the initial sample development stage; 20 15 12, the development summary of the initial sample of the detector system and the review of the design of the normal sample are completed, and the detector system is transferred to the development stage of the normal sample? In June 2020, the factory review of the detector was completed; In July 2020, the detector arrived at the launch site by air, and the work of the launch site was carried out for nearly five months. 1October 24th, 2020, 165438+ The highly anticipated Chang 'e V rose into the sky to build the space history of China? Nine days of the moon? Historical monument. What is the picture below? Chang 'e? Launch schedule of series detectors.

? Subsequently, Chang 'e-5 probe went through the stages of 1 1 launching into orbit, earth-moon transfer, braking in recent months, flying around the moon, landing and descending, working on the moon surface, rising on the moon surface, rendezvous and docking, sample transfer, waiting around the moon, moon-earth transfer, reentry and recovery, which lasted for 23 days.

?

? In less than 1 month, Chang 'e-5 probe has refreshed the depth of deep space exploration technology in China for many times, and achieved many firsts in China, namely, automatic sampling on the lunar surface for the first time, taking off from the lunar surface for the first time, unmanned rendezvous and docking and sample transfer in lunar orbit for the first time, and bringing lunar soil back to Earth at a speed close to the second universe for the first time. Not only that, the unmanned rendezvous and docking and sample transfer in the lunar orbit completed by Chang 'e V is the first time in the world, adding a new record in the history of lunar exploration in the world.

I am not only deeply moved here, but also wish the motherland's space industry better and better.
