八年前的今天，嫦娥三号成功落月！Today, 8 years ago, Chang’e-3 successfully landed on the moon!
As of Month of December 2021, The CNSA –China National Space AdministrationCLEP- China Lunar Exploration Program Belt and Road Initiative Lunar Mission……Chang’e-4with Yutu One the Lunar rover Today in 15th December on 14th December 2013 in which is on eight years ago 2013 the CNSA CLEP China National Space Administration – China Luna Exploration Program Chang’e-3 probe successfully landed on the moon China- People’s Republic of China becomes the third country in the world A country capable of independently implementing a soft landing on the moon on Sinus Iridium Nearby Mare Imbrium ….
8 years ago Chang’e-3 makes the five-star red flag China’s Flag debut on the moon on that day Review looking through back in time eight years ago on The historical moment of the successful landing of Chang’e-3 Lunar Lander.. landing on the The landing site of China’s first Moon lander Chang’e-3 has been named “Guang Han Gong（广寒宫） (Guang: widely, extensively; Han: cold, freezing；Gong: Palace) ” or “Moon Palace” by the International Astronomical Union (IAU), China’s State Administration of Science, Technology and Industry for National Defense (SASTIND). Three nearby impact craters were given the names Zi Wei, Tian Shi and Tai Wei, three constellations in traditional Chinese astrology
On December 14, 2013, China’s first unmanned moon landing probe, Chang’e-3, successfully landed on the moon. The setting moon starts at an altitude of 15 kilometers. During the 11-minute setting of the moon, Chang’e-3 relied on autonomous control to go through six stages: main deceleration, rapid adjustment, approach, hovering, obstacle avoidance, and slow descent. 1.7 kilometers per second gradually reduced to 0. At an altitude of 100 meters from the lunar surface, the probe stopped temporarily and used sensors to observe the landing area to avoid obstacles and select a landing site. After walking the last few meters in free fall, the four landing legs that steadily “stand” on the surface of the moon touched the moon, indicating that Chang’e-3 landed perfectly in the Hongwan area of the moon.
The landing site of Chang’e-3 has good communications and sunshine conditions in the Hongwan area of the moon, and the terrain is relatively flat. No human probe has ever visited before. This area, later named “Guanghan Palace” by the International Astronomical Union, is not only the landing site of Chang’e-3, but also a new starting point for China’s lunar exploration.
While achieving a soft landing on the moon, Chang’e-3 also shoulders the mission of breaking through key technologies such as automatic patrol surveys, deep space measurement and control communications, and moon night survival. The Chang’e-3 lunar probe consisting of the lander and the “Yutu” lunar rover has a total weight of nearly 3.8 tons. In the following time, the “Yutu” left the lander and began scientific exploration, and the lander conducted in-situ detection at the landing site.
Chang’e-3 did not live up to high expectations. It saw the earth on the moon for the first time, obtained images of the earth’s plasma layer for the first time, and completed the first geological profile of the moon and the first celestial body survey. With the successful completion of the mission of Chang’e-3, China’s three-step strategy of “orbiting, landing, and returning” for China’s lunar exploration project has progressed smoothly, and has begun to fully enter a new stage of unmanned automatic sampling and return.
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.

A partial lunar eclipse will be visible in Hong Kong on November 19 (Friday). This is the second lunar eclipse this year, after the first one in May. Members of the public may enjoy this event during the evening when the Moon rises from the east-northeast horizon. At the time of moonrise at 5:38pm that day, the “maximum eclipse” stage has already ended. The Moon is leaving the umbra gradually and the partial eclipse ends at 6:47pm when the Moon exits the Earth’s umbra completely. The whole eclipse ends when the Moon leaves the penumbra at 8:06pm.
The Hong Kong Space Museum will live stream the partial lunar eclipse on that day. Curators will introduce the science behind lunar eclipse and share interesting titbits related to this astronomical phenomenon.
