#CNSA #ChinaNationalSpaceAdministration #国家航天局 |#BeltAndRoadinitiative #December2021| #CCTV9 #ChinaCentralRadioandTelevision #CLEP #ChinaLunarExplorationProgram The Chinese lunar exploration project series documentary “Our Journey” will be broadcast 24th December 2021 that’s tomorrow!

中国空间站 On currently on 24th to 26th December 2021 Christmas eve, CNSA –China National Space Administration  in collaboration with CCTV9 China Central Radio and Television will telecast  “Our Journey” is the first panoramic documentary produced by China National Space Administration and China Central Radio and Television in 4 years to show the complete course of China’s lunar exploration project in 17 years . It is a documentary . Documentary works with international vision, international expression, and international standards are excellent works that tell Chinese stories, spread space culture, and popularize space knowledge

The documentary consists of three episodes, each of 50 minutes, which truly presents the development of China’s lunar exploration project over the past 17 years, which has been through ups and downs, and left a tortuous but full history. This imprint records not only a huge and complicated super project, but also a testimony to the rapid growth of China’s aerospace industry and the common progress of the Chinese nation. The film fully and vividly interprets the spirit of lunar exploration of “chasing dreams, exploring courageously, coordinating fortifications, and win-win cooperation” , promotes the spiritual pedigree of the Chinese Communists , and conveys the spiritual power that China’s scientific and technological development and progress rely on.

 Through character interviews, important development scenarios, and the combined application of various methods such as related materials, the film outlines the continuous and staggered cooperation and support between the various development units of the major systems, and demonstrates the Chinese people’s fearlessness in scientific exploration. Pursuit, as well as the admirable courage and wisdom devoted to this journey full of risks and challenges.

“Our journey” documentary will be held December 24 – the 26th in the Central Radio and Television CCTV-9 record channel 20:00 prime time heavy launch a new media center video, CCTV and other platforms will also be broadcast simultaneously.

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.……  

​​At 23:10 on December 3, 2020, the Chang’e-5 ascender carried a lunar sample to take off from the lunar surface. About 6 minutes later, it entered an elliptical orbit around the moon. At 2:13 on December 6, the ascender accurately reached the scheduled “handover” position 50 kilometers in front of the orbit-return assembly and about 10 kilometers above it. At 5:42, the ascender and the orbit-returning assembly completed the rendezvous and docking. At 6 o’clock, the sample packaging container was transferred from the ascender to the returner. This process of autonomous rendezvous and docking and sample transfer is like the handover process in a 100-meter relay race. It is brilliant and highly technical. Using a lunar orbital rendezvous and docking after take-off from the lunar surface, rather than a direct lunar-to-ground transfer after taking off from the lunar surface, this design is conducive to collecting and carrying more samples back to the earth, and for technical accumulation and verification for subsequent missions.

Aspect 1-chase in space

Both the ascender and the orbit-back assembly fly around the moon, but the orbital heights are different. The ascender runs on the outer track at a height of 210 kilometers, and the orbit-back assembly runs on the inner track at a height of 200 kilometers. The distance on the inner track is short, the track-back assembly runs slightly faster, and the ascender on the outer track runs slower. In order to realize the “transfer bar”, the rail-back assembly needs to raise the rail in the height direction and gradually approach the ascender in the front and rear direction. When approaching a certain distance, the orbit-back assembly will autonomously control the engine to change the direction of travel and take a shortcut to catch up with the ascender. During the entire chase process, multiple anchor points are set up, and the orbit-return assembly stops to keep the relative position unchanged, conducts a state inspection, and ensures that the measurement and control conditions meet the requirements during docking.

 Aspect 2-“High-precision measurement” + “Know yourself and the enemy”

During the rendezvous and docking process, it is necessary to make the orbit-return assembly and the ascender know the relative position, speed and attitude of each other. For this reason, a variety of sensors for relative measurement are configured to realize relative navigation. When the distance is 100 kilometers, the microwave radar starts to work. It not only provides the relative motion parameters of the two devices according to the traditional radar “call and answer” mode, but also upgrades to the “dialogue exchange” mode, between the orbital assembly and the ascender. Two-way transmission of remote control commands and telemetry parameters. At a distance of 20 kilometers, lidar “comes on the scene” to provide higher-precision measurement information. At about 100 meters, the optical sensor began to show its talents to achieve close distance and attitude measurement. These sensors are relayed to each other over the working distance and covered and connected, so as to ensure that there are at least two different systems of sensors available at any distance, so that the orbit-back assembly can be seen more accurately, the measurement is more precise, and the system is more reliable. 

Aspect 3-precise “handover baton” from 380,000 kilometers away

The weight of the orbit-return assembly is more than 2 tons, but the mass of the ascender is only one-sixth of its mass. If the traditional collision docking is used, it is very easy to cause the ascender to be knocked into flight. For this reason, a claw-type catching and docking mechanism is specially designed. Each pair of claws is like two arms, which are quickly closed within 1 second to form a closed space, and the passive lock handle of the ascender is firmly restrained inside. Can’t escape. It has to be accurate, and the accuracy requirement after docking is better than 0.5 mm, which is like “threading a needle” in space. The use of 3 sets of claw mechanism star-shaped circumferential layout and self-centering design realizes the automatic centering of the two aircraft after docking, and realizes the lightweight design while ensuring high-precision docking.

The design of the transfer mechanism is also very clever. In order to realize the transfer of long-stroke sample containers of more than six hundred millimeters, the designers found inspiration from the inchworm. Based on the principle of movement stroke amplification + relay transfer, they proposed a relay mechanism for imitating the inchworm. The simple circular expansion and contraction movement of the parallel link can realize the continuous movement of the object. The entire transfer process is like the movement of a caterpillar, stretching and shrinking, continuously advancing.

#iPhonePhotography #LunaPhotography | #Auckland #NewZealand – Wintery 26th June 2018- before the #FullMoon- A Gallery

Moon as seen previously on that month of 2018 June in first quarter with its timeless terminator lines


On a 26th June 2018, on wintery cold Winterfell  Auckland New Zealand night in which the air was frozen, cold it was as during that month it was like finding Wildlings from the North of the Wall of Westros to Hug for warmth..  During the moon of June was heading towards the Full Moon on the 28th June 2018, in which it lit up the whole night sky as it approached towards the second quarter of the moon. In which before the second quarter becomes whole, as it before it heads towards the Full moon, full Waxing Gibbous … also has it transiting in between the winter constellations of Sagittarius, Scorpio, towards the Libra then Virgo.. from early to modestly later in the night sky from east..


As the moon gathers towards the full moon, in which that form new moon towards the full moon there’s some interesting features that presented before the moon get white washed hiding its details of Cratered cased shadows of the in which those shadows stretches many Kilometers long enough to encompass any major cities on earth..

Among with before the full moon is the outlining of the craters in which during the first quarter is the line of craters in which some of the best features of a first quarter is the area where Tycho Crater is in which leading down to the Jade Rabbit in which is the Sea of Tranquillity, and Serenity in where Tranquillity is where NASA’s Apollo Astronauts landed on 20th July 1969 on the eleventh Apollo Mission in whereas Serenity is the last eighteenth Apollo mission..

In looking downwards from the from the line of where the Mare, transition from Latin is the Sea’s in where large early sections of the moon where it’s flat, where Mare Iridium in which you’ll explore some untouched regions of the moon where it’s least bombard with craters in which is excepted where there’s a large crater Copernicus is situated… among with Kepler..

As I’m keyboarding this post on the 29th October 2017 it’s the #ObservetheMoon is International Observe the moon night  in which the moon will be currently least sixty five percent waxing gibbous in which Luna the moon reveals more her full moon lacy cratered wedding dress towards on the fifth November 2017……..On  a relative  clear spring  Yesterday in Auckland New Zealand night in with during that week’s night sky in which was a previously week was a rain out week thought out the country in which as I’m keyboarding this post.. It has relativity retracted the clear fine day in replacing with a cloudy rainy day…  As it was 24th October 2017 the moon Luna shade with the Earth shadow at seventeen percent Waxing Gibbous in which was four day –nights ago from the New Moon in which the Earth Shadow casted giving a total Waning Gibbous on the 20th October 2017..

As the moon was trending towards the Waxing Gibbous in which unveiling the earth shadow Terminator lacy veil, in which showing her Luna cratered embroidery lacy wedding dress slowly, as Luna rises little later by little away from the Constellation Scorpio as itself too settles earlier among with the planet Saturn looking at averagely of one billion Kilometers away also one hour ago back in time..

As this week night on the 26th October 2017, Auckland Observatory-Stardome, in which while working during the past eight in the evening that interesting night interestingly noticing a very bright transiting object transiting from the constellation Scorpio towards the Southern Cross from westward to the south is the International Space Station in which nibbling tracking looking through the eight inch Meade … looking through the lens finding it was a flat H, in which seeing the main solar panels of the international space station, with the structural trust, in which in the center is the looking at the living modules of the space station itself, in which the main radiators in which lens flared the main central station’s central structure..

If you’re wondering about tonight on the eighth of September 2017 at Auckland Observatory-Stardome,  they’re screen one of the iconic episode sequels from Star Trek The Original Series – “Space Seeds” that was prequel foretold in the storyline of the crew of NX-01 Enterprise as there was Argument Humans-Superhuman that ruled half of Earth over a short period of time in the late 20th  to the early 21st  century then the remaining  crew with its leader Khan Noonien Singh forcefully exile on a sleeper sub-light ship the Botany Bay..  Until then they were discovered by the crew of nearly 40 year old Constitution class USS Enterprise under Captain Kirk the story goes from there until Khan and his crew was again exile at Ceti Alpha four.. In from after that you’ll have to find out in which screening tonight at Stardome-Auckland Observatory at eight New Zealand time for the … “ Star Trek-Wrath of Khan” ….

As of yesterday one the 7th September 2017 Auckland –New Zealand, last night it was a great night as it was the full moon in which there was a modest moderate of crowds for the night in viewing the full moon, in which brighten up the night sky… in which you can see along the other side which the terminator has slightly came back along the side where the Jade Rabbit is… is slowly progressively veiling towards the new moon in which as it tends toward the new moon the moon rises later in the evening ….. Orthough it was great night in viewing the full moon, in which you can still make out the constellations and clusters in the night sky after an earlier much clearer night sky after it rained out the smog pollutants in the air… As for the moon orthough it was full, the features of the moon were washout, but you can see some shadowy indention craters…
