On 20:23 on November 29th Sunday 2020, Hong Kong- Beijing time The Chang’e-5 probe brakes again and enters a nearly circular orbit around the moon….. According to the CNSA China National Space Administration- CLEP- China Lunar Exploration Program at 20:23 on November 29, Beijing time, the Chang’e-5 probe “brakes” again at the near-moon point. From an elliptical orbit around the moon to a nearly circular orbit around the moon. Later, the Chang’e-5 probe will choose an opportunity to separate the lander and ascender combination from the orbiter and returner combination. The lander and ascender combination will carry out a frontal soft landing on the moon, and automatic sampling of the lunar surface will be carried out as planned the picture shows the first near-moon braking picture…… Later, the Chang’e-5 probe will choose an opportunity to separate the lander and ascender combination from the orbiter and returner combination. The lander and ascender combination will carry out a soft landing on the moon’s front, and carry out tasks such as automatic lunar surface sampling as planned

 11月29日20时23分，嫦娥五号探测器在近月点再次“刹车”，从椭圆环月轨道变为近圆形环月轨道。

后续，嫦娥五号探测器将择机实施着陆器和上升器组合体与轨道器和返回器组合体的受控分离。着陆器和上升器组合体将进行月球正面软着陆，按计划开展月面自动采样等工作。

Previously.. On at 20:58 on November 28th 2020 Saturday, Hong Kong- Beijing time The Chang’e-5 probe successfully implemented the “brake” braking and successfully entered the orbit around the moon….. According to the China National Space Administration- CLEP- China Lunar Exploration Program , at 20:58 on November 28, Beijing time, the Chang’e-5 probe flew to the moon after about 112 hours. The 3,000-N engine ignition was successfully implemented at a distance of about 400 kilometers from the lunar surface. About 17 minutes later, the engine shut down normally. According to the monitoring and judgment of real-time telemetry data, the Chang’e-5 probe braked normally in recent months and entered the orbit around the moon smoothly. Near-moon braking is one of the key orbital controls during the flight of the lunar probe. When the high-speed probe approaches the moon, it will apply “brake” braking, in order to make its relative speed lower than the moon’s escape speed, so that it will be captured by the moon’s gravity. The Chang’e-5 probe underwent two orbit corrections during the Earth-Moon transfer process and achieved the expected goal. In the future, the Chang’e-5 probe will adjust the height and inclination of the orbit around the moon, the lander and ascender assembly will be separated from the orbiter and returner assembly, implement the lunar frontal soft landing, and carry out the lunar surface automatic sampling as planned. .

During the every so constant delicate tracking at Xi’an Satellite Measurement and Control Center successfully completed the first near-month brake measurement and control work of Chang’e-5] “The near-month brake orbit control is turned on!” “Linhai’s tracking is normal! The remote data is normal!” At 20:00 on November 28 At 58 minutes and 38 seconds, the Jiamusi Deep Space Station of the Xi’an Satellite Measurement and Control Center successfully placed a remote control command from the Beijing Aerospace Flight Control Center. The engine of the Chang’e-5 probe was successfully ignited and the engine shut down normally after 17 minutes. According to real-time telemetry data monitoring and judgment, the Chang’e-5 probe successfully entered an elliptical orbit around the moon, and the first near-moon braking was a complete success……

​​ 11月28日20时58分，嫦娥五号探测器经过约112小时奔月飞行，在距月面400公里处成功实施3000牛发动机点火，约17分钟后，发动机正常关机。根据实时遥测数据监视判断，嫦娥五号探测器近月制动正常，顺利进入环月轨道。

近月制动是月球探测器飞行过程中关键的轨道控制之一。高速飞行的探测器在靠近月球时，实施“刹车”制动，目的是使其相对速度低于月球逃逸速度，从而被月球引力捕获。

嫦娥五号探测器在地月转移过程中经历了2次轨道修正，达到预期目标。后续，嫦娥五号探测器将再进行一次近月制动，将椭圆环月轨道调整为近圆形环月轨道。

Previously more……Onto 22 hours and six minutes into on November 24th 2020, the 3000N engine of the Chang’e-5 probe worked for more than 2 seconds, successfully completed the first orbit correction, and continued to fly to the moon. As of the first orbit correction, the systems of the Chang’e-5 probe were in good condition and had been in orbit for about 17 hours, about 160,000 kilometers away from the earth.

​​​​ During the flight of the Chang’e-5 probe, affected by various factors, it will produce orbit deviation. It is necessary to determine the deviation between the actual flight orbit of the probe and the designed orbit, and complete the corresponding orbit control to ensure that the probe is always flying in the proper on track.

The Chang’e-5 mission launched into orbit with high accuracy, and the orbit correction is very small this time.

 11月24日22时6分，嫦娥五号探测器3000N发动机工作2秒多，顺利完成第一次轨道修正，继续飞向月球。截至第一次轨道修正时，嫦娥五号探测器各系统状态良好，已在轨飞行约17个小时，距离地球约16万公里。

嫦娥五号探测器在飞行过程中，受各种因素影响，会产生轨道偏差，需要测定探测器实际飞行轨道与设计轨道之间的偏差，完成对应的轨道控制，确保探测器始终飞行在适当的轨道上。

嫦娥五号任务发射入轨精度很高，本次轨道修正量很小。

As of 23rd October 2020, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission on the One Hundred Kilometer diameter Von Karman Crater    Chang’e 4 lander and the “Yutu 2” lunar rover the Chang’e-4 lander and the “Yutu-2” lunar rover Chang’e 4 lander and “Yutu 2” lunar rover usher in As the celestial bodies move, night falls once again on the back of the moon. The Chang’e 4 lander and the “Yutu 2” lunar rover completed the 23rd day of the month. At 21:40 and 12:00 on October 23, they completed the moon night mode setting according to ground instructions and entered moon night sleep. As of today, the Chang’e-4 lander and the “Yutu-2” lunar rover have successfully worked on the back of the moon for 660 earth days, traveling a total of 565.9 meters.

Based on the data of the panoramic camera stitched images and DOM images on the 22nd day, the “Yutu-2” lunar rover travelled to the basalt distribution area and the impact crater area with higher reflectivity during the 23rd day. Both locations are Located northwest of the lunar rover. In this travel route, the infrared imaging spectrometer performed a spectral detection of a rock block with a diameter of about 30 cm. The scientific research team is conducting in-depth research on the detection data. During the 23-month scientific exploration, the lander’s lunar surface neutron and radiation dose detector carried out the world’s first on-site- on-site particle radiation environment detection on the lunar surface, and obtained precious first-hand scientific data. The research results are in Science Advance Journal published.

The moon surface neutron and radiation dose detector can comprehensively measure the total particle radiation dose, neutral particle radiation dose, particle radiation LET spectrum, neutrons, and charged particles on the moon surface. The actual measurement results show that the particle radiation dose rate near the landing zone is 13.2uGy/h(si), the dose equivalent is twice that of the surface of Mars and the interior of the space station, 5 to 10 times of a flight, and 300 times of the surface of the earth (Beijing).

The measured monthly radiation dose (the horizontal axis is Universal Time, the vertical axis are respectively: a total radiation dose rate in silicon (microGray/hour), b. neutral particle radiation dose rate in silicon (microGray) /Hour), c. The charged particle radiation dose rate in silicon (microGray/hour), d. The cosmic ray penetrating particle flux (pieces/square centimeter·hour·radian) measured monthly surface radiation dose (horizontal The axis is Universal Time, and the vertical axis are: a total radiation dose rate in silicon (microGray/hour), b. neutral particle radiation dose rate in silicon (microGray/hour), c. silicon Charged particle radiation dose rate (microGray/hour), d.

These field measurement results provide important radiation environment parameters for the follow-up lunar exploration in my country. The load also distinguishes the radiation dose of charged particles and neutral particles, thereby providing more accurate radiation physical quantities, which can serve the radiation protection of future astronauts.

Today in the history of spaceflight on 24th October :

On October 24, 2007, my country’s first lunar exploration satellite, Chang’e-1, was successfully launched by the Long March 3A carrier rocket at the Xichang Satellite Launch Center, opening the glorious course of my country’s lunar exploration project. On November 12, 2008, the full moon image taken by Chang’e-1 was released. On March 1, 2009, the satellite hit the moon in a controlled manner as scheduled. The successful implementation of this mission marked my country’s entry into the world deep space exploration club and established the third milestone of China’s spaceflight after artificial satellites and manned spaceflight.

On October 24, 2014, my country’s first-month high-speed reentry aircraft was launched from the Long March III C-modified II carrier rocket at the Xichang Satellite Launch Center, and it orbited the moon three days later. On November 1, the returner landed in Siziwang Banner, Ulanqab City, Inner Mongolia, China. As a pilot mission of the third phase of the lunar exploration project, it verified the key technology of lunar sampling and returning, laying a solid foundation for lunar sampling and returning.

月表中子与辐射剂量探测仪可对月表的粒子辐射总剂量、中性粒子辐射剂量、粒子辐射LET谱、中子、带电粒子进行综合测量。实测结果表明，着陆区附近粒子辐射剂量率为13.2uGy/h(si)，剂量当量是火星表面和空间站内部的2倍，一次航班的5到10倍，地球表面（北京）的300倍。

As of 24th September Thursday 2020, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission on the One Hundred Kilometer diameter Von Karman Crater    Chang’e 4 lander and the “Yutu 2” lunar rover the Chang’e-4 lander and the “Yutu-2” lunar rover… Chang’e 4 lander and “Yutu 2” lunar rover awakened autonomously and entered the 22nd day of work] Today, the Chang’e 4 lander and “Yutu 2” lunar rover, which have been working on the back of the moon for 630 days…..  In following.. The Chang’e-4 lander and the “Yutu-2” lunar rover will finish the 22nd month day work at 7:30 on September 24 and 23:18 on the 23rd, and complete the moon night mode setting according to ground instructions, and enter moon night sleep. Up to now, Chang’e-4 has spent 630 Earth days on the back of the moon and travelled 547.17 meters cumulatively.

Based on the 21st month day panoramic camera stitched images, DOM images and other data, the “Yutu 2” lunar rover mainly travels during the 22nd month day, successively in the impact crater and reflection about 1.3km northwest of the landing site Areas with higher rates were detected.

Researchers have made use of data such as panoramic camera ring-shot detection, infrared imaging spectrometer calibration detection, and simultaneous detection of lunar radar during driving, and obtained a number of scientific results, which were recently published in the International Journal of Nature Astronomy.

The scientific team conducted in-depth research on the radar detection data and obtained important discoveries about the lunar soil and shallow structures in the landing zone. Based on the characteristics of low-frequency radar signals, as shown in Figure 1, the shallow structure of the landing area is divided into three basic units, from top to bottom there are strong reflection units (unit 1), weak reflection units (unit 2), and medium reflection units. Unit (Unit 3). Combining basic constraints such as regional geology and the spatial distribution of large-scale impact craters, the results of the geological interpretation are as follows: Unit 1 (total thickness of about 130m) is the accumulation of sputtering materials near multiple impact craters (including Finsen, Alder, and von Carmen). Impact craters such as L and L’) and the basalt breccia layer at the bottom; unit 2 (total thickness about 110 m) is a basalt layer with multiple eruptions; unit 3 (thickness not less than 200 m) is Leibniz in the north of the landing zone Spatter from impact craters. The high-frequency radar signal further gives the fine structure of the upper part of the unit 1, as shown in Figure 2, which is characterized by the presence of a 12m thick lunar soil layer on the top, which basically does not contain large rocks, and the bottom is a strip of 22m thick Sputters, they are all projectiles from the Finsen impact crater, with a total thickness of 34m.

    The lunar radar carried by the “Yutu-2” lunar rover can obtain the geological section below the driving path and reveal the layered structure of the underground. Because the lunar radar is directly based on the lunar surface for detection, the reflected signal detected by it has large energy and clear characteristics, and the effect is far better than that of spaceborne radars more than 100km away from the lunar surface. Moreover, due to the use of a frequency much higher than 5MHz of the spaceborne radar, its resolution advantage is also very obvious. The main frequencies of the two channels of the lunar radar are 60MHz and 500MHz, the spatial resolution is 10m and 0.3m, and the detection depth is about 50m and 500m. The high-frequency channel is used to detect the high-resolution structure of the shallow lunar soil and its underlying sputter, and the low-frequency channel is used to detect the layered structure of the deep sputter and basalt.

The shallow structural profile obtained by the lunar radar shows that the lunar material detected by “Yutu 2” comes from the Finsen impact crater, not from the filling basalt of the von Karman impact crater itself; at the same time, the radar profile also reveals the landing area has experienced multiple impacts, sputtering accumulation and multiple basalt magma eruptions filling. These new discoveries are of great significance for understanding the evolution of the Moon’s South Pole-Aiken Basin, and have an important guiding role for the subsequent exploration and study of the composition and structure of the Moon’s internal material.

嫦娥四号着陆器和“玉兔二号”月球车分别于9月24日7时30分、23日23时18分结束第22月昼工作，按地面指令完成月夜模式设置，进入月夜休眠。截至目前，嫦娥四号已在月球背面度过630个地球日，累积行驶547.17米。

基于第21月昼全景相机拼接影像、DOM影像等数据情况，“玉兔二号”月球车在第22月昼期间主要以行驶为主，先后在距离着陆点西北方向约1.3km的撞击坑和反射率较高的区域进行了探测。

科研人员利用全景相机环拍探测、红外成像光谱仪定标探测、测月雷达行驶过程中同步探测等数据，取得多项科学成果，近期发表在Nature Astronomy国际期刊上。

科学团队对雷达探测数据开展了深入研究，获得了着陆区月壤和浅层结构的重要发现。基于低频雷达信号特征，如图1所示，将着陆区的浅层结构划分为三大基本单元，由上往下依次为强反射单元（单元1）、弱反射单元（单元2）和中等反射单元（单元3）。结合区域地质和大型撞击坑的空间分布等基本约束，地质解译结果如下：单元1（总厚度约130m）为临近多个撞击坑的溅射物堆积（包括芬森、阿尔德、冯·卡门L和L’等撞击坑）和底部的玄武岩角砾层；单元2（总厚度约110 m）为多次喷发的玄武岩层；单元3（厚度不小于200 m）为着陆区北部莱布尼兹撞击坑的溅射物。高频雷达信号进一步给出单元1上部的精细结构，如图2所示，其特征为顶部存在厚达12m的月壤层，基本不含大石块，其下为厚达22m的条带状溅射物，它们均是来自芬森撞击坑的抛射物，总厚度达34m。

    “玉兔二号”月球车搭载的测月雷达能够获取行驶路径下方的地质剖面，揭示地下的分层结构。由于测月雷达直接基于月面进行探测，因此，其探测到的反射信号能量大，特征清晰，效果远优于距月面100km以上的星载雷达探测。而且，由于采用远高于星载雷达5MHz的主频，其分辨率优势也十分明显。测月雷达两个通道的主频分别为60MHz和500MHz，空间分辨分别为10m和0.3m，探测深度分别约50m和500m。高频通道用于探测浅部月壤及其下伏溅射物的高分辨结构，低频通道用于探测深部溅射物和玄武岩等分层结构。

测月雷达所获取的浅层结构剖面表明“玉兔二号”所探测的月面物质来自于芬森撞击坑，而不是来自冯·卡门撞击坑自身的充填玄武岩；同时，该雷达剖面还揭示了着陆区经历多期次的撞击溅射堆积和多期次玄武岩浆喷发充填。这些新发现对于认识月球南极-艾肯盆地的演化具有非常重要的意义，对于月球内部物质组成和结构的后续探测与研究有重要指导作用。
