On 12th December 2020 morning Hong Kong -Beijing Saturday, the Beijing flight control team of the CNSA China National Space Administration– CLEP- China Lunar Exploration Program Belt and Road Initiative Mons Rumker Luna Mission during at that time stamp at 9:54 morning Hong Kong –Beijing time on December 12th 2020…., the Chang’e-5 orbiter and returner combination experienced about 6 days of waiting around the moon, and implemented the first lunar-to-ground transfer incident, changing from a near-circular orbit to a near-moon height An elliptical orbit of about 200 kilometers. The main purpose of the lunar-to-earth transfer and incidence is to move the orbital maneuver on the lunar orbit to make the orbiter and returner assembly enter the lunar-to-earth transfer orbit.
Later, the orbiter and returner assembly carrying the lunar sample will choose the opportunity to implement the second lunar-to-earth transfer incident, so as to get rid of the lunar gravity, enter the lunar-earth transfer orbit and return to the earth.
The engine is turned on and the orbital control begins” “According to the Beijing real-time data monitoring and judgment, the Chang’e-5 orbiter combination has the first lunar-ground incident control, normal and finished, and the follow-up work will fly as normal Implementation of the control planning to returning back to earth in which is expected to land at the Inner Mongolia …..
嫦娥五号轨道器和返回器组合体实施第一次月地转移入射
12月12日9时54分，嫦娥五号轨道器和返回器组合体经历了约6天的环月等待，实施了第一次月地转移入射，从近圆形轨道变为近月点高度约200公里的椭圆轨道。月地转移入射的主要目的是通过月球轨道上的轨道机动，使轨道器和返回器组合体进入月地转移轨道。
后续，携带月球样品的轨道器和返回器组合体将择机实施第二次月地转移入射，从而摆脱月球引力，进入月地转移轨道返回地球。
On 8th December 2020 morning Hong Kong -Beijing Wednesday, the Beijing flight control team of the China National Space Administration- CLEP- China Lunar Exploration Program Belt and Road Initiative Mons Rumker Luna Mission ….At 6:59 on December 8, the Chang’e-5 ascender was controlled off-orbit according to ground instructions, and landed at the scheduled landing point near 0 degrees longitude of the lunar surface and 30 degrees south latitude at about 7:30.
Previously, the Chang’e-5 ascender achieved the first take-off of an extraterrestrial celestial body in my country. It rendezvoused and docked with the orbital return assembly in a predetermined orbit, completed the transfer of lunar samples, and was separated from the orbital return assembly smoothly at 12 o’clock on December 6. Experts from the National Space Administration’s Lunar Exploration and Space Engineering Center said that the Chang’e-5 ascender has successfully completed its mission. The controlled deorbiting and landing of the moon can prevent it from becoming space junk and avoid affecting the international community’s subsequent lunar exploration missions. This is China’s responsibility also an important commitment of major powers to the peaceful exploration and use of space by mankind…..
完成使命——嫦娥五号上升器受控撞月
12月8日6时59分，嫦娥五号上升器按照地面指令受控离轨，7时30分左右降落在月面经度0度、南纬30度附近的预定落点
此前，嫦娥五号上升器实现我国首次地外天体起飞，在预定轨道与轨返组合体交会对接，完成月球样本转移，并于12月6日12时许与轨返组合体顺利在轨分离。国家航天局探月与航天工程中心专家表示，嫦娥五号上升器已圆满完成使命，受控离轨落月可避免其成为太空垃圾，避免影响国际社会后续月球探测任务，这是中国作为负责任大国对人类和平探索利用太空的重要承诺。

再次分离，择机返回——嫦娥五号对接组合体顺利分离
12月6日12时35分，嫦娥五号轨返组合体与上升器成功分离，进入环月等待阶段，将择机返回地球。
Previously On 6th December 2020 Sunday, the Beijing flight control team of the China National Space Administration- CLEP- China Lunar Exploration Program Belt and Road Initiative Mons Rumker Luna Mission – December 6th 2020- Sunday, the Chang’e-5 ascender successfully rendezvous and docked with the orbiter and returner assembly, and the sample container was safely transferred to the returner at 6:12 Morning Hong Kong – Beijing Time. This is the first time that my country has realized lunar orbital rendezvous and docking.
From the moment the ascender enters the orbit around the moon, through long-range guidance and short-range autonomous control, the orbiter and returner assembly gradually approach the ascender, capture the ascender by claws, and complete the rendezvous and docking….. In which the Chang’e-5 ascender successfully rendezvous and docked with the orbiter and returner assembly, and the sample container was safely transferred to the returner at 6:12. This is China’s first lunar orbital rendezvous and docking…….. In the future, the Chang’e-5 orbiter and returner combination will be separated from the ascender and return to Earth at the right time.

Previously On 3rd December 2020 Thursday, the Beijing flight control team of the China National Space Administration- CLEP- China Lunar Exploration Program Belt and Road Initiative Mons Rumker Luna Mission – At 23:10 Hong Kong Beijing time on December 3rd Thursday 2020, the 3000N engine of the Chang’e-5 ascender worked for about 6 minutes and successfully sent the ascender carrying the sample to the scheduled orbit around the moon. This is the first time that my country has realized the take-off of an extraterrestrial body.
Unlike ground take-off, the Chang’e-5 ascender does not have a mature launch tower system for lunar take-off. The lander is equivalent to the “temporary tower” of the ascender. The plume diversion space is limited and the earth-moon environment is different; in addition, because there is no navigation constellation on the moon, after the ascender takes off, it needs to use its own special sensors to realize autonomous positioning and attitude determination with the help of ground measurement and control.
Before taking off, the upper assembly is used to realize the deployment of the lunar flag and the unlocking and separation of the ascender and the lander. This national flag deployment is the first time that my country has achieved an “independent display” of the national flag on the surface of the moon. In the photo, the national flag in the hands of “Chang’e” is shining in the sun, and the “Chinese red” on the moon is particularly bright. After igniting take-off, the ascender undergoes three stages of vertical ascent, attitude adjustment and orbit injection, and enters the scheduled orbit around the moon. Subsequently, the ascender will rendezvous and dock with the orbital assembly waiting around the moon and transfer the lunar sample to the returner, which will wait for a suitable lunar-earth entrance window to prepare for its return to Earth.
飞离月球——嫦娥五号上升器进入预定轨道 实现我国首次地外天体起飞
12月3日23时10分，嫦娥五号上升器3000N发动机工作约6分钟，成功将携带样品的上升器送入到预定环月轨道。这是我国首次实现地外天体起飞。
与地面起飞不同，嫦娥五号上升器月面起飞不具备成熟的发射塔架系统，着陆器相当于上升器的“临时塔架”，上升器起飞面临起飞初始基准与起飞平台姿态不确定、发动机羽流导流空间受限、地月环境差异等挑战；另外由于月球上没有导航星座，上升器起飞后，需在地面测控辅助下，借助自身携带的特殊敏感器实现自主定位、定姿。
点火起飞前，着上组合体实现月面国旗展开以及上升器、着陆器的解锁分离。此次国旗展开是我国在月球表面首次实现国旗的“独立展示”，照片中“嫦娥”手中的国旗在阳光的照耀下，月球上的一抹“中国红”格外鲜艳。点火起飞后，上升器经历垂直上升、姿态调整和轨道射入三个阶段，进入预定环月飞行轨道。随后，上升器将与环月等待的轨返组合体交会对接，将月球样品转移到返回器，后者将等待合适的月地入射窗口，做好返回地球的准备。
