As of 7th January 2021 Thursday, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission……Chang’e-4 successfully awakened and entered the 26th day of the work period….Waking up  Chang’e 4 awakened smoothly and entered the 26th day of work….. With a new round of dawn on the back of the moon, Chang’e 4 ushered in the 26th day of the month, and the “Yutu 2” lunar rover at 10 o’clock on January 7 waking up at 29 minutes, the lander woken up at 03:13 on January 8. As of today, Chang’e-4 has been in operation for 736 Earth days, continuing to refresh the record of human probes working on the back of the moon.

During the day of this month, the lunar rover will continue to travel towards the basalt distribution area or the impact crater area with high reflectivity (approximately 27m from the current detection point, and there is a degenerated impact crater with a diameter of approximately 160m in the south of the crater), both of which are located in the northwest direction of the current detection point.

With a new round of dawn on the back of the moon, Chang’e 4 ushered in the 26th day of the month. The “Yutu 2” lunar rover awakened at 10:29 on January 7 and the lander at 03:13 on January 8 wake. As of today, Chang’e-4 has been in operation for 736 Earth days, continuing to refresh the record of human probes working on the back of the moon.

During the day of this month, the lunar rover will continue to travel towards the basalt distribution area or the impact crater area with high reflectivity (approximately 27m from the current detection point, and there is a degenerated impact crater with a diameter of approximately 160m in the south of the crater), both of which are located in the northwest direction of the current detection point.

The following exploration activities are planned during the day of this month:

(1) It is preferable to take a panoramic camera ring shot near noon of the moon.

(2) Detection and calibration of infrared imaging spectrometer.

(3) The neutral atom detector is turned on for detection.

(4) Synchronous detection of lunar radar during driving. The scientific research team will continue to conduct scientific analysis on the acquired detection data, and relevant results will be released in time.

 

Previously……. As of 22 December 2020, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission The “Yutu-2” lunar rover has a mileage exceeding 600 meters, completing the 25th day of work….The Chang’e 4 lander and the “Yutu 2” lunar rover completed the 25th day of the month at 5 o’clock on December 22 and 19:22 on the 21st, respectively. The moon night mode setting was completed according to ground instructions and entered moon night sleep. As of today, the Chang’e-4 lander and the “Yutu-2” lunar rover have been working on the moon for 719 days, and the lunar rover has travelled 600.55 meters in total……

Researchers conduct research and analysis on the detection data obtained in 25 months, and continue to produce scientific results. A recent scientific achievement published in the internationally authoritative academic journal Astrophysical Journal Letters (Xu et al 2020) shows that the lunar neutron and radiation dosimeter mounted on the Chang’e-4 lander detected a solar high-energy particle event on the back of the moon (SEP). This is the first time that a human probe has detected SEP on the surface of the moon, verifying the performance of the instrument, and also made a detailed analysis of the acceleration mechanism and the acceleration source area of the SEP.

Previous observations made by Chang’e-4 indicate that the radiation intensity on the surface of the moon is about 100 times that of the earth (Zhang et al. 2020, Space. Adv.). Since the moon does not have the same atmosphere and magnetic field as the earth, the Galactic cosmic ray (GCR) can easily reach the surface of the moon. Such high-intensity background radiation can cause damage to astronauts working on the surface of the moon. In addition, when solar activity erupts, the solar high-energy particle event will cause the particle flux to increase by thousands of times, and the space radiation will also be greatly enhanced. Therefore, the observation of the arrival of high-energy particles of the sun on the moon is particularly important.

In 2019, the sun is in a very small year, no sunspots have appeared for a long time, and the chance of observing solar high-energy particle events is even smaller. Chang’e-4 captured such an event. The study found that both electrons and protons exhibit good velocity dispersion. By linearly fitting the data points, it is possible to deduce the release time of particles from the acceleration zone and the distance the particles travel in interplanetary space before reaching the moon.

In addition, the proton energy spectrum of this SEP event was further analysed, including the GCR background energy spectrum and the background subtracted energy spectrum. According to the energy spectrum with the background subtracted, the dashed power law spectrum is used to fit it, and it is found that the energy inflection point is about 2.5MeV….

天问一号飞運騎遊達达3亿 …….As of the early morning January 3rd 2021, CNSA – China National Space Administration- ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen- Martian Probe One …… The Tianwen-1’s flight mileage exceeded 400 million kilometers….. As of 6:00 on January 3, the Tianwen-1 probe has been in orbit for 163 earth days, with a flight mileage of over 400 million kilometers, about 130 million kilometers from the earth, and about 8.3 million kilometers. The probe has a stable attitude. According to the plan, it will implement near-fire braking in more than a month, enter the ring-fire orbit, and prepare to land on Mars.

The Tianwen-1 mission is the first step in China- People’s Republic of China independent interplanetary exploration. It will “circle, land, and patrol” Mars through a single launch, that is, Mars orbit, Mars landing, and fire patrol. The Tianwen-1 probe has a total weight of about 5 tons and is composed of an orbiter and a landing patrol device. The landing patrol device mainly includes an entry module and a Mars rover. At present, the orbiter has completed the third on-orbit self-check, and all systems are working normally…..

截至2021年1月3日6时，天问一号探测器已在轨飞行163天，飞行里程突破4亿公里，距离地球约1.3亿公里，距离火星约830万公里，飞行状态良好。按计划将在一个多月后实施近火制动，进入环火轨道。

天问一号任务是我国独立开展行星际探测的第一步，旨在通过一次发射实现对火星的“绕、着、巡”，即火星环绕、火星着陆、火面巡视。天问一号探测器总重约5吨，由环绕器和着陆巡视器组成，着陆巡视器主要包括进入舱和火星车。目前，环绕器已完成第三次在轨自检，各系统工作正常。

探月逐火共奋进，追梦求真向天行。行星探测“天问工程”是月球探测“嫦娥工程”的再发展，是中国人探索宇宙星辰征程的再延伸。中国深空探测事业一步一个脚印，一棒接力一棒，继承与创新并举，稳妥与挑战兼具。现在，探月工程“绕、落、回”三步走发展规划圆满收官，天问一号正在抵近火星，带着中国人民的期愿飞向这颗神秘的红色星球。

天问一号飞運騎遊達达3亿 …….As of the early morning Monday of 14th December, 2020, CNSA – China National Space Administration- ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen-1 …….Tianwen-1 probe is more than 100 million kilometers away from the earth] It is learned from the National Space Administration that as of 21:00 Hong Kong – Beijing Time on December 14, the Tianwen-1 probe has been in orbit for 144 days, with a flight mileage of approximately 360 million kilometers, and is far from the earth. Over 100 million kilometers, about 12 million kilometers away from Mars, the flight is in good condition. Affected by the laws of movement of celestial bodies, the distance between Mars and the Earth varies periodically from 50 million kilometers to more than 400 million kilometers. When the Tianwen-1 rover arrived near Mars, it was about 190 million kilometers away from Earth. Since the launch of Tianwen 1 on July 23, it has successfully completed a group photo of the earth and the moon, “Selfie” of the probe, three midway corrections, a deep-space manoeuvre, and payload self-check. In the follow-up, several orbit corrections will be carried out. It is expected that after approaching Mars in mid-February next year, “brake” braking will be implemented to enter the ring fire orbit in preparation for Mars landing. (杨璐戚铁磊) #Tianwen 1 probe is more than 100 million kilometers away from the earth 我们的空间…… In the follow-up, Tianwen-1 will conduct several orbit corrections. It is expected to “brake” after approaching Mars in February next year and implement braking into the ring fire orbit.

The hometown is far away and the goal is getting closer. 100 million kilometers is equivalent to 2,499 the length of the earth’s equator. Now, Tianwen-1 is flying to Mars at a ground speed of 17.4 kilometers per second…….

 Previously………天问一号飞運騎遊達达3亿 …….As of the previously morning Tuesday of November 17th, 2020, CNSA – China National Space Administration- ESA – European Space agency Belt and road initiative mars mission…first Mars exploration mission, Tianwen-1, has been in orbit for 116 days, with a flight mileage of more than 300 million kilometers. The earth is approximately 63.8 million kilometers. The detector’s attitude is stable, the energy is balanced, some sub-systems have completed self-checking, and each system is working normally.

During its orbital flight, Tianwen-1 has completed three midway corrections and one deep-space manoeuvre and other flight control tasks. In early November, the landing patrol vehicle entry module and multiple sub-systems of the Mars rover completed the first on-orbit self-check, and the results were normal.

Tianwen-1 is scheduled to reach Mars in February 2021 and carry out Mars capture. In May 2021, it will choose an opportunity to de-orbit, and the landing patrol will be separated from the orbiter, soft landing on the surface of Mars, the rover will leave the landing platform, and the inspection will be carried out…. For the Martian exploration..

Previously On the 9th October 2020 Friday 2300 hours Beijing time CNSA – China National Space Administration that under the control of the flight control team of China’s first Mars exploration mission, the main engine of the Tianwen-1 probe was ignited. In more than 480 seconds, the deep space manoeuvre was successfully completed. The orbital manoeuvre was carried out in deep space approximately 29.4 million kilometers from the earth. The orbit design of Tianwen-1 comprehensively considered various constraints from launch to Mars capture and made the propellant consumption as small as possible, and adopted the strategy of a deep space manoeuvre during the transfer process. The probe will rendezvous with Mars about 4 months after its current orbit, during which two or three midway corrections will be implemented……

Previous the last course correction … during On October 1st 2020, as China- People’s Republic of China also throughout the Chinese also the Asian Communities celebrates the National Day and Mid-Autumn Festival; CNSA China National Space Administration released China’s first Mars exploration mission Tianwen-1 exploration….. The image of the CNSA Belt and Road Initiative European Space Agency collaboration Martian Probe flying, the five-star red flag on the picture is dazzling, showing a bright Chinese red. This is the first deep space self-portrait of our country 天问一号 Martian probe. In the vast universe, the silver landing patrol device and the golden orbiter are shining brightly. Tianwen No.1 uses this to report safety to China and express birthday wishes.

As we all know, when taking selfies on the ground, you can use auxiliary tools such as selfie sticks to shoot after choosing the angle, light and shadow, but the selfie of “Tianwen No. 1” is not that simple. Due to its large size, if the selfie stick strategy is adopted, “Tianwen No.1” needs to use a 15-meter-long selfie stick to achieve a full-view selfie, which not only consumes resources, but is also prone to safety risks. For this reason, the Mars Orbiter Engineering Survey Sub-system Team of the Eighth Academy of Sciences proposed a “separated monitoring plan”, which is to “throw out” a light camera under suitable lighting conditions to take pictures of “Tianwen No. 1” and transmit the images in real time. Go back to the “Tianwen No. 1” probe.

Have you seen a one-time dual-head super wifi camera?………In order to successfully implement the separate monitoring program, the Eighth Academy Mars Orbiter Engineering Measurement Sub-system team needs a little guy who can “divide, shoot clearly, pass back, and hold on”: use a small, small, low-impact unlocking separation device The camera can be “divided out”; the use of colour imaging, the configuration of 800×600, 1600X1200 two-level resolution camera allows the image to be “clearly captured”; the use of super Wi-Fi communication that can achieve 400 meters of wireless communication allows data “Passed back”; the use of disposable batteries that can provide power for longer than 1 hour allows the camera to “hold on”, allowing the ground to see the full picture of the “Tianwen No. 1” rushing to the fire.

Considering that the camera may turn over as it gradually moves away from the detector, the development team designed the camera as a dual-headed front and back to ensure that the camera can capture as many detector images as possible during the turning process. After four years of research and development, this little guy weighing about 950g successfully carried the “Tianwen-1” Mars probe into space, and successfully separated the head weighing about 680g, and obtained a clear image. Successfully completed the overall visual monitoring task of “Tianwen No. 1”

The name “Tianwen”: 天問 ….. Comes from the long poem of the same name written by Qu Yuan (about 340–278 BC), one of the greatest poets of Ancient China. It is a poem of a series of questions starting with how the universe was created.

“玉兔二号”月球车行驶里程突破600米，完成第25月昼工作

科研人员对25个月昼所获得的探测数据进行研究分析，持续产出科学成果。近期发表于国际权威学术期刊Astrophysical Journal Letters(Xu et al 2020)上的一篇科学成果表明，搭载在嫦娥四号着陆器上的月球中子和辐射剂量仪在月球背面探测到了一个太阳高能粒子事件（SEP）。这是人类探测器首次在月球表面探测到SEP，验证了仪器性能，也对SEP的加速机制和加速源区做了详细分析。

嫦娥四号之前的就位观测结果表明，月球表面的辐射强度大约是地球上辐射强度的100倍左右（Zhang et al. 2020, Space. Adv.）。由于月球没有像地球一样的大气和磁场，银河宇宙线（Galactic cosmic ray，GCR）可以轻松到达月球表面，这样高强度的背景辐射会对在月球表面作业的宇航员造成损伤。此外，当太阳活动爆发时，太阳高能粒子事件还会导致成千上万倍的粒子流量增长，空间辐射也会极大增强。因此，对太阳高能粒子到达月球的观测尤其重要。

 2019年，太阳处于活动极小年，很长时间没有太阳黑子出现，观测到太阳高能粒子事件的机会更是很小。 嫦娥四号捕捉到了这样一个事件。研究发现，无论是电子还是质子都表现出很好的速度弥散，通过对数据点进行线性拟合，可以推出粒子从加速区释放的时间以及粒子到达月球前在行星际空间传输的距离。

此外，进一步分析了这次SEP事件的质子能谱，包括GCR背景的能谱以及扣除背景的能谱。根据扣除背景的能谱，利用破折幂律谱对其进行了拟合，发现能量拐点大概为2.5MeV。​​​​

Previously  of 26 August 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 have completed 21-month scientific exploration on the back of the moon. They broke through 677 Earth  Days On the far back of the moon, the Chang’e 4 lander and the “Yutu 2” lunar rover ended their moon night dormancy at 3:12 on November 10 and 10:17 on November 9 respectively. They were awakened by light and ushered in the first 24 days. Up to now, Chang’e-4 has successfully operated for 677 Earth days.

Based on the data of the panoramic camera spliced images and DOM images of the detection point, the “Yutu-2” lunar rover will continue to drive northwest during the 24th day of the month, targeting the basalt direction or the impact crater area with high reflectivity. Near the noon of the moon, the “Yutu-2” lunar rover plans to take at least one panoramic camera ring shot, and the infrared imaging spectrometer, neutral atom detector, and lunar radar will carry out simultaneous detection.

Go to the nearest impact crater with brighter reflectivity (purple circled area), the red circle is the location of the rock block

  As the “Yutu-2” lunar rover continues to move northwest, scientists from the core team of Chang’e-4 use the first-hand data returned to continue to produce scientific results. The scientific team recently published an article in the SCI journal “Science China Information Sciences” and pointed out that the impact during the formation of the Antarctic-Aitken Basin is likely to penetrate the lunar crust and impact deep lunar material.

Since the remote sensing observation of the back of the moon by orbiting satellites, a large number of studies have revealed the existence of mafic anomalies at the bottom of the Antarctic-Aitken Basin, which also have different chemical properties compared to returned samples and lunar meteorites. Chang’e-4 probed the sputter layer at the bottom of the impact crater in the Antarctic-Aitken Basin and found that the characteristics of mafic minerals in this area are similar to remote sensing data.

Research data shows that the mafic minerals in the rocks and lunar soil in the Chang’e 4 landing area are dominated by clinopyroxene, which has the same composition as the rapidly cooling magma system. It is believed that the material in the landing zone of Chang’e 4 mainly comes from the recrystallization of the impact melt. The patrol and detection of “Yutu-2” in this area provided a scientific basis for in-depth understanding of the cause of the mafic anomaly at the bottom of the Antarctic-Aitken Basin….

在遥远的月球背面，嫦娥四号着陆器和“玉兔二号”月球车分别于11月10日3时12分和11月9日10时17分结束月夜休眠，受光照自主唤醒，迎来第24月昼。截至目前，嫦娥四号已顺利工作677个地球日。​

基于探测点全景相机拼接影像、DOM影像等数据情况，“玉兔二号”月球车将在第24月昼期间继续向西北方向行驶，目标为玄武岩方向或反射率较高的撞击坑区域。在接近月午时，“玉兔二号”月球车计划进行至少1次全景相机环拍，红外成像光谱仪、中性原子探测仪、测月雷达开展同步探测。

 随着“玉兔二号”月球车向西北方向不断前行，嫦娥四号核心团队科学家利用传回的第一手数据，持续产出科学成果。科学团队近期发表在SCI期刊《Science China Information Sciences》上的一篇文章中指出：南极–艾特肯盆地形成时的撞击很可能穿透月壳，撞击出月球深部物质。

自轨道卫星实现对月球背面的遥感观测以来，大量研究揭示南极-艾特肯盆地底部存在镁铁质异常，相比返回样品以及月球陨石，也有着不同的化学特性。嫦娥四号通过对南极-艾特肯盆地撞击坑底部溅射物层的探测，发现该区域镁铁质矿物特征与遥感数据相似。

研究数据显示，嫦娥四号着陆区的石块及月壤中镁铁质矿物以单斜辉石为主，这种辉石成分与快速冷却的岩浆系统一致。研究认为嫦娥四号着陆区物质主要来自撞击熔融体的重结晶。“玉兔二号”在这一区域的巡视探测为深入认识南极-艾特肯盆地底部镁铁质异常区的成因提供了科学依据。​​​​

On 17th December 2020 very early morning Hong Kong -Beijing Thursday, 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 …..Chang’e-5 probe successfully completed China’s first extraterrestrial celestial body sampling and return mission…. At 1:59 Hong Kong –Beijing Time on December 17th early hours morning Thursday, the lunar exploration project Chang’e-5 returner successfully landed in the planned area of ​​Siziwang Banner, Inner Mongolia, marking The mission of sampling and returning to China’s first extraterrestrial body was successfully completed.

 

At about 1 am, the Beijing Space Flight Control Center injected high-precision navigation parameters into the Chang’e-5 orbiter and returner combination through the ground measurement and control station. After that, the orbiter and the returner were normally unlocked and separated at a height of about 5,000 kilometers above the sea level of the South Atlantic, and the orbiter completed the evasion manoeuvre as planned. At 1:33 in the morning, the Chang’e-5 returner entered the Earth’s atmosphere at a high speed close to the second cosmic speed (about 11.2 kilometers per second) at a height of about 120 kilometers above the ground, and performed the first aerodynamic deceleration. After descending to a predetermined height, the retractor jumps up out of the atmosphere and begins to glide down after reaching the highest point. After that, the returner enters the atmosphere again and performs a second aerodynamic deceleration. When descending to a height of about 10 kilometers above the ground, the retractor opened the parachute to complete the final deceleration and maintain a stable attitude, and then landed smoothly in the predetermined area. The technical personnel of the measurement, control and recovery system responsible for the search and recovery task discover the target in time and carry out the recovery work in an orderly manner.

 

 According to the plan, the recovered Chang’e-5 returner will be airlifted to Beijing to open the cabin after completing the necessary ground handling work to take out the sample container and the cargo. CNSA China National Space Administration will select the opportunity to hold a handover ceremony to officially hand over lunar samples to the ground application system. It’s is the first China- People’s Republic of China  first extraterrestrial celestial body sample storage, analysis, and research related work will also start.

During the duration of monitoring   and tracking …..Huashan, the forecast of the landing point has been issued…….At around 2 o’clock on December 17 Thursday, 2020, in the command hall of the Technical Department of the Xi’an Satellite Measurement and Control Center, tracking the progress successfully escorted the Chang’e 5, which had been traveling in space for 23 days, back to the embrace of returning to  China ! It is understood that in this mission, the Xi’an Center is mainly responsible for high-precision orbit determination, long-range guidance strategy calculation for lunar orbit rendezvous and docking, calculation of lunar ascent windows, and lunar return to landing prediction. Among them, the calculation of the long-range guidance strategy of the lunar orbital rendezvous and docking and the calculation of the lunar ascent window are the first in my country…

Also during the Duration Tracking is also Yuanwang 3 ship will escort Chang’e 5 through a term for re-entry as the “black barrier”…. When Chang’e 5 returns, it will use the “earth-moon free return orbit” landing technology commonly known as the “drift” orbit. Because it is close to the second universe speed, It will enter the black barrier due to high-speed flight and atmospheric friction, and in the black barrier area will bounce up under the block of the dense atmosphere, be “bounced” back into space by the upper atmosphere, and then enter the atmosphere again for normal landing. At present, the Yuanwang 3 ship is in the Indian Ocean mission area to prepare for the telemetry, external survey, and optical measurement missions near the “black barrier” of the Chang’e-5 returner’s first re-entry into the atmosphere…..

Previous the last course correction … during On October 1st 2020, as China- People’s Republic of China also throughout the Chinese also the Asian Communities celebrates the National Day and Mid-Autumn Festival; CNSA China National Space Administration released China’s first Mars exploration mission Tianwen-1 exploration….. The image of the CNSA Belt and Road Initiative European Space Agency collaboration Martian Probe flying, the five-star red flag on the picture is dazzling, showing a bright Chinese red. This is the first deep space self-portrait of our country 天问一号 Martian probe. In the vast universe, the silver landing patrol device and the golden orbiter are shining brightly. Tianwen No.1 uses this to report safety to China and express birthday wishes.

As we all know, when taking selfies on the ground, you can use auxiliary tools such as selfie sticks to shoot after choosing the angle, light and shadow, but the selfie of “Tianwen No. 1” is not that simple. Due to its large size, if the selfie stick strategy is adopted, “Tianwen No.1” needs to use a 15-meter-long selfie stick to achieve a full-view selfie, which not only consumes resources, but is also prone to safety risks. For this reason, the Mars Orbiter Engineering Survey Sub-system Team of the Eighth Academy of Sciences proposed a “separated monitoring plan”, which is to “throw out” a light camera under suitable lighting conditions to take pictures of “Tianwen No. 1” and transmit the images in real time. Go back to the “Tianwen No. 1” probe.

Have you seen a one-time dual-head super wifi camera?………In order to successfully implement the separate monitoring program, the Eighth Academy Mars Orbiter Engineering Measurement Sub-system team needs a little guy who can “divide, shoot clearly, pass back, and hold on”: use a small, small, low-impact unlocking separation device The camera can be “divided out”; the use of colour imaging, the configuration of 800×600, 1600X1200 two-level resolution camera allows the image to be “clearly captured”; the use of super Wi-Fi communication that can achieve 400 meters of wireless communication allows data “Passed back”; the use of disposable batteries that can provide power for longer than 1 hour allows the camera to “hold on”, allowing the ground to see the full picture of the “Tianwen No. 1” rushing to the fire.

Considering that the camera may turn over as it gradually moves away from the detector, the development team designed the camera as a dual-headed front and back to ensure that the camera can capture as many detector images as possible during the turning process. After four years of research and development, this little guy weighing about 950g successfully carried the “Tianwen-1” Mars probe into space, and successfully separated the head weighing about 680g, and obtained a clear image. Successfully completed the overall visual monitoring task of “Tianwen No. 1”

The name “Tianwen”: 天問 ….. Comes from the long poem of the same name written by Qu Yuan (about 340–278 BC), one of the greatest poets of Ancient China. It is a poem of a series of questions starting with how the universe was created.
