One year ago today 24th November 2020 Now it’s the 24th November 2021 , the Chang Zheng – Long March Five Carrier Rocket Launched away in CNSA – China National Space Administration China Wenchang spaceport launch, Change Five Lunar probe into orbit, opened up towards China – People’s Republic of China’s first celestial bodies sample return trip from Mons Rumker on the Lunar Surface.……
Highlight 1: Narrow window launch The launch window is the ignition time period for the launch vehicle to meet the needs of the transfer to the moon. Due to the typhoon and strong tropical cyclone in Wenchang area, high-altitude wind, heavy rainfall, thunderstorms and other meteorological conditions are very complicated, it can be imagined. The narrower the window, the greater the risk of launching large cryogenic launch vehicles. There are many factors that determine the launch window, such as the relative position of the launch site and the target point, the safe landing zone of the rocket wreckage, the time of sunlight after the launch probe (satellite) enters orbit, the measurement and control arc, the lunar landing zone, and the lunar take-off time , Re-entry return time, etc. The more the launch constraint conditions, the narrower the launch window. In order to ensure the reliable implementation of the Chang’e-5 mission, it is necessary to solve the design difficulties of the multi-orbit moon launch scheme under the constraints of the range of launch, the safety of the landing zone, the measurement and control of the ascent section, and the rocket taxi time.
Aspect 2: During the two-stage taxiing process of the accurate low-temperature launch vehicle in the landing zone of the rocket, the quality of the propellant will decline with the passage of time, so the longer the taxiing time, the more unfavourable the startup of the low-temperature power system. For this reason, the rocket system has carried out a large number of ground tests, and the three flights of the Long March 5 have fully evaluated and verified the long sliding ability of the model. The rocket area of the Chang’e-5 mission must fly over the Philippine Islands. The booster landing area is located west of the Philippines, the fairing landing area is located east of the Philippines, and the core landing area is located in the Pacific Ocean. Multi-ballistic launching has caused significant horizontal and vertical dispersion in the sub-level wreckage landing area. Therefore, if the mission permits, the range of the shooting direction and dispersion must be minimized to optimize the safety of the landing area. The scientific research team carried out multiple rounds of optimization design for the horizontal and vertical dispersion of the multi-ballistic trajectory to the moon with variable firing direction and variable glide time. In the end, the rocket wreckage landed exactly in the intended sea area. Aspect 3: Multi-trajectory, “moving target shooting”
A key technology in the launch phase of the Chang’e-5 mission is multi-ballistic launch, that is, within 3 consecutive days, there are 5 nominal trajectories with 10 minute intervals between take-offs every day, evenly covering the 50-minute launch window. The purpose of multiple ballistics is to achieve “mobile shooting” with different take-off points and the same destination during the relative movement of the earth and the moon. As long as the launch vehicle ignites within the launch window and sends the probe into a predetermined Earth-Moon transfer orbit, the probe can fly to the near-moon point at exactly the same time, altitude, incident angle, illumination, and measurement and control conditions. Through the detailed orbit design, the outstanding performance of the launch vehicle systems, and the concerted cooperation of various departments, the Chang’e-5 probe was sent into the scheduled orbit with very high accuracy, laying a solid foundation for the subsequent flight missions.

On 9th October 2021 Month in a Hong Kong –Beijing CNSA China National Space Administration- CLEP- China Lunar Exploration Program Belt and Road Initiative Mons Rumker Luna Mission ….. The team of CLEP – China Lunar Exploration CNSA’s lunar and Martian exploration department have release The first research results of Chang’e 5 lunar samples were published in “Science”
Recently, an international research team led by researcher Liu Dunyi from the Beijing Ion Probe Center of the Institute of Geology, Chinese Academy of Geological Sciences, China Geological Survey and Professor Alexander Nemchin, a senior overseas visiting scholar from the Institute of Geology, Australia, is conducting research on the Chang’e-5 lunar samples. Significant progress has been made. The team conducted chronological, elemental, and isotope analysis of the Chang’e 5 lunar basalt, which proved that magma activity still existed on the moon 1.96 billion years ago, providing key scientific evidence for perfecting the evolution of the moon. The related research paper “The Age and Composition of Chang’e 5 Young Basalt” was published online in the international academic journal “Science” in the early morning of October 8, Beijing time. This is the first academic achievement published based on the Chang’e-5 lunar sample. Researcher Liu Dunyi and Professor Alexander Nemchin are the co-corresponding authors of this article. Dr. Xiaochao Che is the first author of this article.
When the moon’s magmatism ceases has always been one of the major scientific issues in the study of the history of the moon’s evolution. Previous studies on lunar samples have not found that there is a magma activity younger than 2.9 billion years on the moon. The sampling location of the Chang’e-5 mission was designed in the lunar sea basalt area, which is the youngest on the lunar surface. A total of 1731 grams of lunar samples were collected through surface sampling and drilling. They were reviewed by the Lunar Sample Expert Committee and reviewed by the Lunar Exploration and Aerospace Engineering Center. , And reported to the National Space Administration for approval that on July 12 this year, the first batch of lunar scientific research samples totaling 31 were distributed to 13 scientific research institutions. Scientists all over the world are full of hope and look forward to obtaining the results of younger magma events from the study of the Chang’e-5 sample, so as to improve the evolution history of lunar magma.
The research team used detailed micro-area in-situ high-resolution secondary ion mass spectrometry (SHRIMP) dating data and solid rock mineral geochemical data to prove that there was still magma activity on the moon until 1.96 billion years ago, making the previously known lunar geology The life span has been extended by about 1 billion years.
At present, scientific research on lunar samples is in progress, the second batch of lunar samples is issued according to procedures, and relevant scientific results will be released in time.

“You” is my glory….”………5, 4, 3, 2, 1, light up!
Wenchang Space Craft Launch Center- Hainan Province – China – People’s Republic of China , 7:10 in the evening.
The launch password was issued on time…..Suddenly, the fire was dazzling, and the Long March- Chang Zheng Five Carrier Rocket standing on the launch tower soared into the sky……
The audience was overjoyed, cheering and cheering echoed with the roar of the rocket, and the scene was unprecedented.
In the measurement and control hall, a man was staring at the screen intently, paying close attention to the flight data until the launch mission was a complete success.
His name is Yu Tu, 38 years old, and the youngest chief designer in the aerospace system.
At this moment, the marginal solar system probe “Sou Shen” developed by his team is flying into space under the support of the Long March Chang Zheng Five Carrier Rocket…
Recently, the TV series “You Are My Glory” ended successfully.
Many “famous aerospace scenes” in reality were restored in the play, which not only made the astronauts who chased the drama praised “it tastes that taste”, but also attracted many young audiences to have a strong interest in the aerospace industry.
Work articles
Are astronauts all masters who stay up late?
This year, China’s aerospace industry has witnessed many happy events. From the “five, get a long day” to “long seven days to send boat people” to “sky send Shenzhou” Aerospace Science and Technology Group “under the dumplings” speed to sweep the now 29 times aerospace launch success , in which multiple tasks They are all executed at night.
“Stay up late to send a rocket” is not to pursue the shocking effect of the rocket taking off and piercing the sky. Instead, the ignition time is “reversed” according to the spacecraft’s orbit determination requirements.
In the play, many “space cuts” come from reality. What other shining points are there for astronauts at work?
【Aerospace cut 1 】 Rescue satellite
No matter where you are, get to the scene as quickly as possible.
f the satellite loses connection, what impact will it have on us?……For example, mobile phone navigation is lost, satellite TV signals are interrupted, and weather forecast errors have increased sharply… And some satellites involved in national defense security have problems, and the consequences are even more disastrous…….One day, Yutu, who was on vacation, received an emergency call, asking him to rush to the work site immediately because of a sudden failure of an orbiting satellite……..The rescue process was twists and turns. Everyone scrambled for more than a second, day and night, looking for the cause and solution of the failure……..As academician Ye Peijian said: “The satellite is lost, I can’t explain it.”
This is not only a national asset worth hundreds of millions of dollars, it is also an important tool related to the national economy and people’s livelihood. Five days later, the satellite returned to its normal state and continued its on-orbit mission .The astronauts are not afraid of difficulties and are especially capable of fighting.……This group of dedicated, persistent, and ideal aerospace youths are all good!
[Aerospace cut 2 ] Don’t let the model go to the sky with doubts
Work harder and check it carefully!
When doing aerospace, I think about things in the sky, so why do experiments on the ground?…..This also starts with Dongfeng-2. That year, as part of the ground test facilities were still under construction, Dongfeng-2 made its first flight before a number of large-scale ground tests were carried out, which resulted in a failure………Since then, China Aerospace has established the principle of “everything passes ground tests” and “never let the models go to the sky with doubts” . It has accelerated the construction of various ground test facilities and carried out ground tests in an all-round way, greatly improving the mission success rate. This tradition has been passed down through generations of astronauts and has been carried forward to the present…….The meeting room was brightly lit, and Yu Tu and his colleagues were helpless……….In the morning, the patrol device had a problem with the simulation test on the ground. Everyone screened each system one by one, but no reason was found………After the people dispersed in the middle of the night, Yu Tu stayed to continue his calculations and investigations……..The next day, he validated his idea last night, and the experiment was a complete success……Astronauts are not afraid of problems, and are especially capable of tackling key problems.……Faced with boring and complex problems, they dealt with calmly, calmly, and efficiently, without leaving a trace of hidden dangers to heaven.
【Aerospace cut 3 】 Rocket launch
In the aerospace field, there is still a gap between us and the world’s top level. But the distance of 30 to 40 years does not mean that it takes 30 to 40 years to catch up. The meaning of my hard work and my colleagues is also here.
There are many bright moments in China’s aerospace industry. What picture is the most burning?
Rocket launch must be the answer in many people’s minds.
This year, the Aerospace Science and Technology Group plans to arrange more than 40 space launch missions, and the curtain on the construction of the Chinese space station in orbit has been opened. By 2030, major engineering projects such as the space exploration program for habitable planets close to the solar system will be implemented.
Yu Tu served as the Chief Instructor for the first time, escorting the “Search God” to the universe, which is a marginal probe of the solar system, looking for another magical possibility in the endless universe….Astronauts are not afraid to endure hardships, they are especially capable of giving.…..Doing aerospace and realizing self-worth in the aerospace dream is the origin of enthusiasm for thousands of astronauts.
Life
Who said that aerospace science and engineering men do not understand romance?
Looking up at the sky, you will find that the romance of astronauts is “cosmic”!
Our manned spacecraft called the “Shenzhou” , the lunar exploration program called “Chang E” , the rover called “rabbit” , planetary exploration mission called “Heaven” , the rover called “Vulcan” , space station called the “Temple” , the satellite navigation system It’s called “Beidou” … Chang’e flies to the moon and Beidou finds its way. The astronauts let the beautiful myths shine into reality, and the astronauts let the romance unique to Chinese culture fly into the sky.
The romance of astronauts does not stop there, such as in life——
【Aerospace cut 4 】 Loving
There is a kind of romance, which is to send the “Rocket” to the person you like. When you miss me, you have it to accompany you.
Some astronauts often lean against a suitcase next to the seat, which contains several changes of clothes and toiletries…..They said that putting a suitcase is convenient for business trips, and you can pick them up and set off immediately…..One heart and Xu Guo are the lofty ambitions of astronauts, but they also have a tender side…..For example, sending “rockets” and writing love letters, even if we get together less and more often, it feels like I am here.
【Aerospace cut 5 】 Marriage proposal
There is a kind of romance, which is to take ID photos together. This matter must be considered carefully. It must be the same location, lighting, and photographer.
Aerospace is a systematic engineering, and any small omissions can lead to huge losses. Therefore, it is the iron law of China Aerospace not to let products go to the sky with hidden dangers. There is no fluke in spaceflight, and we must be rigorous in spaceflight……..In life, once the astronauts become rigorous, they must be serious and attentive…..For example, when two people can take a photo with the same frame under exactly the same conditions……
【Aerospace cut 6 】 Marriage
There is a kind of romance, which is a collective wedding held by aerospace units.
In the Aerospace Science and Technology Group, every year, a unit holds a collective wedding ceremony for aerospace newcomers. As shown in the play, they will join hands to start a new stage of life under the blessing and witness of family members and colleagues.For the astronauts, this special collective wedding is not only a promise to love, but also an oath to the country….
For the rest of my life, I love both Galaxy and you!
The end of the story
“Sou Shen” launch mission was a complete success….. But its journey in the universe has just begun….In order to see more stars,…..China’s spaceflight will…Go ahead and live up to your trust……. Are you chasing “You Are My Glory”?….What is the “famous space scene” in your mind?
