中国空间站 On currently on 24th to 26th December 2021 Christmas eve, CNSA –China National Space Administrationin collaboration with CCTV9 China Central Radio and Television will telecast “Our Journey” is the first panoramic documentary produced by China National Space Administration and China Central Radio and Television in 4 years to show the complete course of China’s lunar exploration project in 17 years . It is a documentary . Documentary works with international vision, international expression, and international standards are excellent works that tell Chinese stories, spread space culture, and popularize space knowledge
The documentary consists of three episodes, each of 50 minutes, which truly presents the development of China’s lunar exploration project over the past 17 years, which has been through ups and downs, and left a tortuous but full history. This imprint records not only a huge and complicated super project, but also a testimony to the rapid growth of China’s aerospace industry and the common progress of the Chinese nation. The film fully and vividly interprets the spirit of lunar exploration of “chasing dreams, exploring courageously, coordinating fortifications, and win-win cooperation” , promotes the spiritual pedigree of the Chinese Communists , and conveys the spiritual power that China’s scientific and technological development and progress rely on.
Through character interviews, important development scenarios, and the combined application of various methods such as related materials, the film outlines the continuous and staggered cooperation and support between the various development units of the major systems, and demonstrates the Chinese people’s fearlessness in scientific exploration. Pursuit, as well as the admirable courage and wisdom devoted to this journey full of risks and challenges.
“Our journey” documentary will be held December 24 – the 26th in the Central Radio and Television CCTV-9 record channel 20:00 prime time heavy launch a new media center video, CCTV and other platforms will also be broadcast simultaneously.
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.

The Tianwen-1, China’s first Mars mission successfully landed on it in May, achieving another extraordinary feat in the recent Chinese Aerospace Industry. This first Mars exploration mission of China is unique that employed novel technology and engineering design and encounters exceptional challenges.
The Mars Landing Surveillance Camera (Mars Camera) is developed mainly by the research team of the Hong Kong Polytechnic University. It is a sophisticated space instrument mounting on the top surface of the lander platform of Tianwen-1, which monitors the landing status, the surrounding environment of the red planet and the operation status of the Zhu Rong rover. The Mars Camera is light in weight, yet strong and durable enough to withstand the huge impact shocks of 6,200 times Earth’s gravity. Moreover, it has to operate under low Martian temperature as well as overcome extreme temperature differences it experienced during its flight. In this lecture, Professor Yung from the Hong Kong Polytechnic University will talk about the challenges of the Mars mission and delineate the contributions of the Hong Kong research team.
