The Chang'e-5 probe is planned to be launched at the end of the year and has now entered the launch site preparation stage
They ran forward for the "moon dream"
This year's "October" coincides with the National Day and Mid-Autumn Festival. People on the ground are busy watching the moon, and the moon in the sky is also waiting for the Chinese probe to visit again.
During the "Eleventh" period, at the Wenchang Space Launch Site in China, the Chang'e-5 probe that my country plans to launch before the end of the year has entered the stage of preparation for the launch site. It is carrying out pre-launch operations together with the Long March 5 carrier rocket for this launch mission. Final assembly and testing.
"'Fat Five' is like our family"
There is such a group of astronauts, for the key step of "return" in the three-step goal of "circumnavigating, landing, and returning" for our country's lunar exploration project, they are running forward to realize the "dream of lunar exploration" of the Chang'e-5 mission.
Many of them have not been able to reunite with their families this holiday, and have stayed at work.
As the "01 command" of the rocket system, Huang Bing from the General Department of the First Academy of China Aerospace Science and Technology Corporation is one of the people who are most familiar with and understand rockets.
Whether it's fairing transfer or rocket plant testing, he always accompanies the "fat five brothers" on the scene to complete every step.
At the launch site, when the reporter met him for the first time, this running aerospace expert was like a soldier. In spite of the high temperature and heat wave in Hainan, he did not dare to step down. He followed the rocket and guarded carefully.
"As far as the Long March 5 carrier rocket for this launch mission is concerned, it was used to launch the Chang'e-5 probe to the moon from the beginning of the project." Huang Bing said.
"The Long March 5 rocket is like our family." Huang Bing said frankly that after the failure of the second launch of the Long March 5 and the success of the third launch, our entire team's understanding of the rocket is improving. The system is becoming more and more mature.
After several subsequent launches, including the successful first flight of the Long March 5B carrier rocket and the successful launch of the "Tianwen-1", we are now more confident in the "Fat Five".
Chang'e-5 is expected to achieve four "firsts"
"The ability of the carrier rocket is as large as the stage of China's aerospace." Huang Bing told reporters that it was not only used for the launch of the Chang'e-5 probe, but the Long March 5, as a representative model of my country's new generation of carrier rockets, has been since its birth. Aiming at the broader universe, it will also undertake the mission of China's spaceflight to perform more major tasks on its shoulders.
According to the plan, Chang'e-5 is expected to achieve four "firsts" in the history of Chinese spaceflight: the first automatic sampling on the lunar surface, the first take-off from the lunar surface, the first unmanned rendezvous and docking in the lunar orbit 380,000 kilometers away, and the first Lunar soil returns to Earth at a speed close to the second universe.
Among them, how to automatically sample on the lunar surface is a difficult problem for Chinese astronauts.
Looking at the world, the United States uses manned landing on the moon to bring back to Earth by artificial sampling from the lunar surface, while what China wants to achieve is to autonomously collect the lunar soil through a probe on the lunar surface.
"Our entire team has been pre-researching a variety of new materials, new processes, and new technologies ten years ago, in order to successfully bring the lunar soil back." At this moment, China Aerospace Science and Technology Group Fifth Academy Chang'e 5 Wang Guoxin, the technical leader of the probe's drilling subsystem, and his colleagues are still sticking to it, and ground tests time after time, in order to finally pass the test on the moon.
"To do aerospace, you must have the strength to run long distances"
This holiday, Zhang Yuhua, deputy commander of the Chang'e-5 probe of the Eighth Academy of China Aerospace Science and Technology Corporation, is still very busy.
She is one of the main persons in charge of the development of the Chang'e-5 probe, the main person in charge of the "Yutu-2" lunar rover that is exploring on the back of the moon, and the deputy of the "Tianwen-1" probe, my country's first Mars exploration mission. The commander-in-chief often travels to and from Beijing, Shanghai, Wenchang and other places.
"The entire Chang'e-5 mission is expected to last about 23 days. The series of difficult actions such as lunar surface sampling, lunar surface take-off, lunar orbital rendezvous and docking, and sample transfer are completed in one go like a space movie. The difficulty and challenges behind it can be imagined. Knowing." Zhang Yuhua said.
"Aerospace is a field that humans continue to explore outward. We often go to distant places that we haven't been to before. Therefore, it represents a spirit of exploration and innovation, and also represents a heroic complex." Zhang Yuhua said that she can be fortunate in this life. In aerospace, every time I look up at the stars, I can see my dedication and hard work. This experience is unparalleled.
In Zhang Yuhua's eyes, deep space exploration and lunar exploration are very valuable in themselves, and the process of exploration means the drive of human curiosity and the advancement of technology.
She said: "To do aerospace, you must have the strength to run long distances. This cycle is very long, and you have to grit your teeth every second."
For Zhang Yuhua and the members of the Chang'e-5 probe test team and all the astronauts who have dedicated themselves to the cause of China's lunar exploration, a new long-distance race is beginning, and Chang'e-5 is ready to go.
