On 13th 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 At 9:51 Morning Hong Kong – Beijing Time on December 13th Sunday, the Chang’e-5 orbiter and returner assembly carried out the second lunar-to-ground transfer incident, which was successfully implemented at a distance of 230 kilometers from the lunar surface. Four 150N engines were ignited. About 22 minutes later, the engine shuts down normally. According to real-time telemetry data monitoring and judgment, the orbiter and the returner successfully entered the lunar-to-earth transfer orbit.
Later, the Chang’e-5 orbiter and returner assembly carrying lunar samples will undergo midway orbit correction during the lunar-to-earth transfer process, and the separation of the orbiter and the returner will be carried out at an opportunity……
12月13日9时51分，嫦娥五号轨道器和返回器组合体实施第二次月地转移入射，在距月面230公里处成功实施，四台150牛发动机点火，约22分钟后，发动机正常关机。根据实时遥测数据监视判断，轨道器和返回器成功进入月地转移轨道。
后续，携带月球样品的嫦娥五号轨道器和返回器组合体将在月地转移过程中进行中途轨道修正，并择机实施轨道器和返回器的分离。
On 12th December 2020 morning Hong Kong -Beijing Saturday, the Beijing flight control team of the 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。
Previously.. On 6th December 2020 Afternoon Hong Kong -Beijing lunch time 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 Separate again, choose an opportunity to return-Chang’e-5 docking complex separates smoothly….At 12:35 Hong Kong – Beijing Time on December 6th 2020 , the Chang’e-5 orbital return assembly was successfully separated from the ascender and entered the waiting phase of the moon, and it will return to the earth at an opportunity.
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.
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.
12月6日5时42分，嫦娥五号上升器成功与轨道器和返回器组合体交会对接，并于6时12分将样品容器安全转移至返回器中。这是我国首次实现月球轨道交会对接。
从上升器进入环月飞行轨道开始，通过远程导引和近程自主控制，轨道器和返回器组合体逐步靠近上升器，以抱爪的方式捕获上升器，完成交会对接。
后续，嫦娥五号轨道器和返回器组合体将与上升器分离，择机返回地球。
