On a very 24th February 2022 Thursday Morning in Hainan Province –China –People’s Republic of China….showering in the district area of the Wenchang – Wenchang Spacecraft launch center in which the awesome team at one of many CNSA –China National Space Administration that China National Space Administration………….. China’s self-developed newly advance medium-sized carrier rocket, the Long March 8, arrived in Wenchang is the Chang Zheng – Long March 8 Yao Carrier Rocket. In set on planned launching on the late February- Early March 2022 Launching schedule …
This morning, the Chang Zheng Long March 8 Carrier Rocket carried out a vertical transfer – VAB- Vertical Assemble Building at the Wenchang Spacecraft Center…… At present, the slewing launch complex platform has been closed and the transfer has ended successfully. The layers of sea fog can’t hide our enthusiasm, and we look forward to seeing the dawn in three days…!
The China Aerospace’s first Chang Zheng Long March 8 Carrier Rocket will deploy 22 satellites” micro-nano starry sky shoulders C position….. In late February 2022, the Chang Zheng Long March 8 Yao 2 Carrier Rocket will perform the “Chang Zheng Long March 8 Carrier Rocket deploying 22 satellites carpool launch mission at the Hainan Wenchang Launch Center. Satellites from 7 units including Micro-Nano Satellites were sent into a 535-kilometer sun-synchronous orbit. Both the number of launches and the launch weight set a new record for the launch of 20 satellites with one arrow set by the Chang Zheng Long March 6 Carrier Rocket in 2015. This mission is also the wonderful debut of ” Chang Zheng -Long March 8″ as China’s second-type “shared rocket” to perform a domestic commercial carpool launch mission.
The total weight of the satellites launched by the Chang Zheng -Long March 8 Yao-2 Carrier rocket this time is about 1.7 tons. Among them, the five satellites independently developed and manufactured by Micronano Star have a total weight of more than 800kg, which is close to half of the total weight of the 22 satellites launched this time. The absolute master of launch missions is. Among them, “Taijing 3 01” is a 0.5m resolution visible light remote sensing satellite, the weight of the whole satellite is close to 240kg; “Taijing 4 01” is the first domestic X-band commercial microwave remote sensing satellite (SAR satellite), The resolution is better than 1m, and the weight of the satellite is close to 350kg. These two satellites firmly occupy the center position of the satellite launched by Long March 8 this time.
The 5 satellites launched by Micro-Nano Star this time, except for Wenchang-1 01 and 02 satellites, have the same technical status, all other satellites (Taijing 3 01, Taijing 4 01, Xidian 1) No.) technology status is different, four technology status, parallel development, parallel production, one rocket launch, this is a huge challenge for any satellite company’s research and development capabilities, and the micro-nano star is for each satellite. Elaborately designed the research and development process, constantly breaking through technical difficulties, the research and development team was awake at night, gave up the opportunity to reunite with their families during the Spring Festival, and went 3,000 kilometers to the Hainan launch site, demonstrating the leading satellite development capabilities and tough work style in the domestic commercial aerospace field. .
On a very 21st January 2022 Friday in Hainan Province –China –People’s Republic of China….showering in the district area of the Wenchang – Wenchang Spacecraft launch center in which the awesome team at one of manyCNSA –China National Space Administration that China National Space Administration………….. China’s self-developed new medium-sized carrier rocket, the Long March 8, arrived in Wenchang is the Chang Zheng – Long March 8 Yao Carrier Rocket. In set on planned launching on the March Launching schedule
According to the First Academy of Aerospace Science and Technology Group, the Long March 8 Yao-2 carrier rockets have recently completed all the research and development work before leaving the factory. After 7 days of sea transportation, it will be safe on January 21, 2022. Arrived at Wenchang Space Launch Site in China.
In the follow-up, the Chang Zheng – Long March 8 Yao Carrier Rocket will complete the final assembly and testing work at the launch site, and it is planned to complete the launch mission at an opportunity from late February to early March. This launch will be the first launch mission of my country’s new generation of carrier rockets in 2022

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.
