At 0:00 on December 16th 2021 Thursday, Hong Kong SAR- Beijing time, the international authoritative scientific magazine “Nature” published the top ten figures of 2021, and Zhang Rongqiao, the chief designer of my country’s first Mars exploration mission, was selected. On May 15, 2021, China’s Mars rover “Tianwen One” successfully landed on the pre-selected landing zone on the surface of Mars. China became the second country in the world to successfully land on Mars and deploy a Mars rover. After the “Zhurong” Mars rover sent back telemetry signals, the flight control center in Beijing lit up a festive red screen, and the engineer excitedly shouted “Hello, Mars!” Zhang Rongqiao took off his glasses silently at this time, tears in his eyes.
The character of the year in “Nature” describes Zhang Rongqiao as “Mars explorer”. Mars is a space nightmare for many countries. So far, the overall success rate is only about 50%, and the success rate for landing missions is only a little over 40%. China’s first Mars exploration mission completed the three major goals of Mars orbiting, landing and patrolling. It is even more difficult and risky. Behind the steadily accomplishing the three goals is the effort to “grind a sword in ten years.” “In order to win today’s first battle, we started planning 10 years ago. We have worked hard for 6 years, held at the launch site for 110 days, and held at the Beijing Aerospace Flight Control Center for 202 days. The first victory was to orbit Mars. After that, I held on for another 93 days to this day. What is the purpose? It is for today’s final victory!” Zhang Rongqiao said excitedly at the flight control center on May 15th.
At a press conference held by the National Space Administration in Beijing on June 12, Zhang Rongqiao said, “Achieving a circumnavigation in one step means that the development is more difficult. To put it more plainly, the possibility of failure increases. For our developers, we can bear it. Zhang Rongqiao said. Fortunately, there is the correct leadership of the Party Central Committee, and there are government organizations at all levels, especially the powerful organization of the National Space Administration, including the Aerospace Science and Technology Corporation, the Chinese Academy of Sciences, and the launch site and measurement and control The competent departments have vigorously coordinated, and the fire detection research and development personnel have worked hard and overcome difficulties. “To put it more bluntly, it is the fire-detector’s vigor. We succeeded today. Looking back, the choice of this technical route is very correct.” Zhang Rongqiao said that overall it is more cost-effective, especially in terms of technology. It can achieve leapfrog development and make my country enter the world’s advanced ranks in the field of planetary exploration in a relatively short period of time. “Therefore, we said that the first Mars exploration mission was based on China’s national conditions and embarked on a path of aerospace development with Chinese characteristics.”
In the future, China will implement deep space exploration missions such as Mars sampling and return missions, near-Earth asteroid sampling and return and main belt comet orbiting missions, Jupiter system orbiting and planetary crossing missions. “Looking up at the stars and keeping your feet on the ground” are two words that Zhang Rongqiao likes very much. He said: “This is precisely what society needs for each of us, and it is a way for us to settle down in society. We need to stand on the present and look to the future.” Zhang Rongqiao Said: “Our knowledge and understanding of the universe is still very superficial. We should see that the world beyond the cradle is infinitely vast. Innovation never ends.”
The Top Ten People of the Year in Nature are records of important scientific developments and events this year, as well as some of the key figures and their colleagues. The top ten figures were selected by the editors of Nature and gathered individuals who influenced some of the most important scientific events in 2021.
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.……
At 23:10 on December 3, 2020, the Chang’e-5 ascender carried a lunar sample to take off from the lunar surface. About 6 minutes later, it entered an elliptical orbit around the moon. At 2:13 on December 6, the ascender accurately reached the scheduled “handover” position 50 kilometers in front of the orbit-return assembly and about 10 kilometers above it. At 5:42, the ascender and the orbit-returning assembly completed the rendezvous and docking. At 6 o’clock, the sample packaging container was transferred from the ascender to the returner. This process of autonomous rendezvous and docking and sample transfer is like the handover process in a 100-meter relay race. It is brilliant and highly technical. Using a lunar orbital rendezvous and docking after take-off from the lunar surface, rather than a direct lunar-to-ground transfer after taking off from the lunar surface, this design is conducive to collecting and carrying more samples back to the earth, and for technical accumulation and verification for subsequent missions.
Aspect 1-chase in space
Both the ascender and the orbit-back assembly fly around the moon, but the orbital heights are different. The ascender runs on the outer track at a height of 210 kilometers, and the orbit-back assembly runs on the inner track at a height of 200 kilometers. The distance on the inner track is short, the track-back assembly runs slightly faster, and the ascender on the outer track runs slower. In order to realize the “transfer bar”, the rail-back assembly needs to raise the rail in the height direction and gradually approach the ascender in the front and rear direction. When approaching a certain distance, the orbit-back assembly will autonomously control the engine to change the direction of travel and take a shortcut to catch up with the ascender. During the entire chase process, multiple anchor points are set up, and the orbit-return assembly stops to keep the relative position unchanged, conducts a state inspection, and ensures that the measurement and control conditions meet the requirements during docking.

Aspect 2-“High-precision measurement” + “Know yourself and the enemy”
During the rendezvous and docking process, it is necessary to make the orbit-return assembly and the ascender know the relative position, speed and attitude of each other. For this reason, a variety of sensors for relative measurement are configured to realize relative navigation. When the distance is 100 kilometers, the microwave radar starts to work. It not only provides the relative motion parameters of the two devices according to the traditional radar “call and answer” mode, but also upgrades to the “dialogue exchange” mode, between the orbital assembly and the ascender. Two-way transmission of remote control commands and telemetry parameters. At a distance of 20 kilometers, lidar “comes on the scene” to provide higher-precision measurement information. At about 100 meters, the optical sensor began to show its talents to achieve close distance and attitude measurement. These sensors are relayed to each other over the working distance and covered and connected, so as to ensure that there are at least two different systems of sensors available at any distance, so that the orbit-back assembly can be seen more accurately, the measurement is more precise, and the system is more reliable.
Aspect 3-precise “handover baton” from 380,000 kilometers away
The weight of the orbit-return assembly is more than 2 tons, but the mass of the ascender is only one-sixth of its mass. If the traditional collision docking is used, it is very easy to cause the ascender to be knocked into flight. For this reason, a claw-type catching and docking mechanism is specially designed. Each pair of claws is like two arms, which are quickly closed within 1 second to form a closed space, and the passive lock handle of the ascender is firmly restrained inside. Can’t escape. It has to be accurate, and the accuracy requirement after docking is better than 0.5 mm, which is like “threading a needle” in space. The use of 3 sets of claw mechanism star-shaped circumferential layout and self-centering design realizes the automatic centering of the two aircraft after docking, and realizes the lightweight design while ensuring high-precision docking.
The design of the transfer mechanism is also very clever. In order to realize the transfer of long-stroke sample containers of more than six hundred millimeters, the designers found inspiration from the inchworm. Based on the principle of movement stroke amplification + relay transfer, they proposed a relay mechanism for imitating the inchworm. The simple circular expansion and contraction movement of the parallel link can realize the continuous movement of the object. The entire transfer process is like the movement of a caterpillar, stretching and shrinking, continuously advancing.
