Book has arrived and I use entire day to read it. Because that's full of China's space project history not just simply something project never going off paper. So I think I need to put it there. And that... that just make a lot of sense of why 921 Project, or the more famous name, the Shenzhou Project can have such rapid progress: Admittedly, technical cooperation with Russia, such as astronaut training, manned spacecraft design and the technical exchange of escape tower technology, is vital. But if without the data from "Shuguang Project", such as data on space medicine, research on space food, airtightness and insulation of space suits, etc. I think I can make some kind spoiler: no one can buy and read this book anyway Chapter 1: Everything is hard at first Back in August 1958, the draft concept for the development of an artificial satellite had already been drawn up: the mission was code-named "Mission 581" because it was classified as the first major mission of 1958. The plan was divided into three steps: the first step was to launch a sounding rocket, of two types: high-altitude physical and biological; the second step was to launch a small satellite, "but not a potato or an egg, like the US, but at least one or two hundred kilograms in weight"; and the third step was to launch a large satellite, weighing several tons or more. So it was at this time that the Chinese Academy of Sciences mainly carried out research on space biology such as animal centrifuges, vibration, low pressure, and biological training. So, the first question before the researchers at this point was: what is high-altitude oxygenation? Relations between China and the Soviet were still good at this time, but there was considerable secrecy on the Soviet side about the advanced and cutting-edge scientific research topics and weaponry of the time. "The new ships of the Baltic Fleet were close at hand, but instead of arranging a visit for us naval colleagues, they made us board a tourist boat on the Neva River. When we reached the shipyard, the curtains on the windows were lowered, as if they were afraid of what we might see. During the professional tour of the ship model experiment pool, even the model ships doing the tests were covered up, obviously to keep it a secret from us. "said by Luo Shunchu, deputy head of the Chinese delegation to the Soviet Union. But perhaps it was the Soviets who felt that the institute of aeromedical sciences was not so sensitive to the usefulness of the Chinese: of course, we the Chinese were always trying to learn something about atomic bombs, missiles and nuclear subs at those times, which quite sensitive even now The technology of how to supply oxygen to pilots at high altitude and low pressure is "really nothing". So, the Soviet agreed to Chinese order for two complete sets of oxygen supply equipment for MiG-21 pilots (The actual introduction of entire MiG-21s in China instead came a year later, in February 1959). Pressurised oxygen supply equipment is available now, the second problem is the low-pressure containment chamber. At this time China had only just emerged from years of war not more than ten years earlier. There wasn't that much metal material available. So, Professor Liang Zhiming from the Mechanics Department of the Nanjing Engineering Institute made calculations and concluded that the concrete culverts of the railway could withstand the enormous pressure and that the low-pressure compartment hull could be constructed entirely of reinforced concrete. The researchers were inspired by the raw lacquer on the very well-preserved wooden figurines when they visited the Nanjing Museum. After consulting a number of chemical experts and receiving the answer that "it is possible to use it in the construction of low-pressure cabins", "they made a kind of putty out of raw lacquer and applied it to the exterior of the cabin, paying special attention to filling in and scraping the gaps between the metal and the concrete, and then painted it with two coats of raw lacquer, resulting in a good sealing layer. The laboratory men also covered the painted pods with another layer of triclinium and a coat of grey paint. For those who don't know they think it's also a metal pod." The result is also quite good: it keeps the cabin air pressure at the equivalent of 10,000 metres above sea level. And for the Chinese the source of technology for high altitude pressure resistant suits and oxygen supply equipment was not only the Soviet Union but also the United States. Time came in 1959 when the Chinese shot down several RB-57D and the U-2. By studying several captured American pilot's G-suites, and oxygen regulators, several institutes of the Academy of Aeronautics and Sciences developed the "6002 pilot's pressure resistant suits". In addition, the researchers identified a serious flaw in the oxygen supply equipment used by the Americans at the time: when the user inhaled at a high flow rate, the sub-membranous chamber of the respiratory valve would change from positive to negative pressure through priming, and under the positive pressure in the helmet, the gas would quickly escape through the expiratory valve, at which point the oxygen supply equipment would lose its ability to supply oxygen to the pilot

Those reminds me a joke years ago I saw in Chinese internet: -You know why there have been fewer UFO sightings and claims of abduction by aliens in recent years? -Why? -Because the camera resolution of smartphones has been increased many times.

Alright there's no surprising launch this year because those official weibo are already posting out the 2022 summarises In 2022, China launched 64 rockets in total. They are: Long March family: 53 times CZ-2D, 15 times CZ-4C, 9 times CZ-2C, 6 times CZ-11 & CZ-3B, 4 times CZ-2F, 3 times CZ-5B, CZ-6, CZ-7, CZ-4B, CZ-6A, 2 times CZ-7A & CZ-8, 1 time Commercial company and CASIC: 11 times and 2 failures CASIC (中国航天科工) KZ-1A, 4 times KZ-11, 1 time Galactic Energy (星河动力) CERES-1, 2 times CAS-Space (中科宇航) LJ-1, 1 time CALT (China Academy of Launch Vehicle Technology, 中国运载火箭技术研究院) JL-3, 1 time Landspace (蓝箭航天) JQ-1, 1 time, failure i-Space (星际荣耀) SQX-1, 1 time, failure In these 64 launches, JSLC were carried out 25 times, XSLC 21 times (WSLS 6 times), TSLC 15 times and launch at Yellow Sea 3 times (2 cold launch and 1 hot launch) (Fun fact: Wenchang Space Launch Site is belonging to the XSLC) According to publicly available information, there are 159 satellites/spacecrafts have been sent in scheduled orbits by these 64 launches this year.

The last launch this year. And someone made some stunning shots! "The satellite is mainly used for in-orbit validation tests of new technologies such as space environment monitoring.", said by CCTV's official weibo.

In 1960s to 70s, the one of the craziest times, there had a manned spacecraft project in China called Shuguang-1 (The Chinese pronunciation of this word sounds very good to me). And I found interview transcripts with quite a lot of detail of the earliest Chinese astronauts but who never went into space. And yep, it's fully Chinese. Now, 'Shuguang' become the dispatch code for the astronaut system on manned missions. In one way or another, it's a tribute to these pioneers.

Saturn. One night when I was a child, while walking the dog with my father in the vacant lot below our house, an astronomy enthusiast was looking at Saturn through a telescope. Then I saw Saturn through his telescope: it was the first planet I ever saw through a telescope, and it was really shock to me.

At least it looks better than the thing from the 2014 YOG in Nanjing.

I didn't got this during my three almost four years of study in the UK by never eating indoors when I go out and wearing face mask: thank you 3M. And, as we know, China deregulation of the epidemic this month. I bought my parents a bunch of sterilised stuff based on my experience in the UK, but they may have been negligent somewhere along the line and still unfortunately contracted an infection. But "luckily" I have rented a house outside and live on my own. My father just like got a fever, and my mum's sound becomes a duck for a day. My other elders have all been infected in the last week, including my grandmother, who is a "priority protect" by our family. But there was still no one can escape from the infection. But the good news is that she is in good health, and she is fine now. All of us in the office got COVID except me and another female colleague. But the good news is that several of our colleagues have recovered and returned to work in this week.

Science game? How about Dyson Sphere Program?

Introduced by a friend to a lady who is pretty chatty and then she can play French horn: as a typical Chinese who can play piano and viola, honestly, playing this was like some kind of magic to me.

Speaking of which, another remote sensing satellites A pomegranate for the patch. My stereotypical northern fruit.

"How to save your cost as possible?"

Nice summary. But apart from those mentioned in the video, the most attracted me was the remote sensing satellites were launched almost every month on average. If we add up the SAR and optical remote sensing satellites, it even seems at least two launch missions each month in 2022. Thank you CZ-2D, which the rocket with most launches in 2022 Hope everything goes well for the Landspace's Zhuque-2 Y2 next year!

Found a video from The Institute of High Energy Physics of the Chinese Academy of Sciences about that day and opening the cover on it: https://www.bilibili.com/video/BV1kX4y1T7W2/?spm_id_from=333.788.recommend_more_video.-1&vd_source=6fef304b8d0c4737896e6b702ddfbfb3 (relax there's no human language in the video) This should be the purest water you've ever seen

The solar panels rotate in the direction of the sun. A paper from CMS (or other institute I forget) said, "the solar panels shifted from Tianhe to both end of the modules will rotate with the truss to orientate to the sun. Therefor the transferred solar panels are not equipped with their drive mechanism and actuator." This means that the original drive mechanism will remain on the Tianhe. I think it's possible that new extra-vehicular experimental platforms will be added to these two areas if the capacity allows and there's a corresponding demand.

Read and watch those about the Dark Matter and suddenly remain me something: There's a nuclear power station called 'Daya Bay Nuclear Power Plant' about half hour drive east from my home. Then, 360m away from this, under a granite mountain, there have (or had) a neutrino experiment facility. When I was in secondary school, the school even organised a visit to this nuclear power station. And this neutrino laboratory made the headlines of our local newspaper that day about ten years ago when my parents still subscribed to the newspaper. Then I wanted to see if there were any new developments or founding from here, only to find that it had been decommissioned in end of 2020 because the accuracy of the measurement of the amplitude of neutrino oscillations couldn't be improved. "In fact, when the experimental setup was first designed, it was designed to the highest precision possible at the time. 'The Daya Bay Neutrino Experiment has gone 17 years from its design to now. Today, if we were to redesign it again, we still wouldn't be able to improve the accuracy because we've reached the limit.', said by the leader of this experiment, Wang Yifang" The successor of it is Jiangmen Underground Neutrino Observatory

Video taken by another witness What a turn it made!

Watch a video about a group of astronomy enthusiasts in the outskirts of Beijing who captured the CSS and ISS appearing in the night sky at the same time On the bottom left is CSS and top right is ISS. This opportunity is quite rare have to say, but since the video doesn't even have a single English character, I won't put the link. If you're curious, the Chinese subtitle in the screenshot reads "Quietly crossing each other under the sky with full of stars".

Wu Yansheng, Party Secretary and Chairman of CASC, was make a speech to introducing what was Chinese space program was did, what are doing right now, and the ambition of the future. (Of course there's no English subtitles) In addition to the 'standing dish' about plans for CZ-9, NGCS (next-generation crewed spacecraft) and the accompanying new manned rocket. There's something new (But not that new): "For on-orbit service and maintenance, we plan to have an on-orbit service and maintenance system consisting of three systems: high-orbit service, orbital transfer and efficient low-cost transportation by 2030. Disrupt existing spacecraft development, launch, deployment, and application models. Significantly improve the effectiveness of the use of our space assets." "Around 2025, near-Earth asteroids and main belt comets will be explored. Implementation of a Mars sample return mission in the next 10 to 15 years." "Planetary exploration of the Jupiter system and Uranus; solar exploration and solar system edge exploration. The flight distance will reach 100 AU by the 100th anniversary of the founding of China." "Around 2030, the 'Mi Yin (I think can translate to Sound Searching) project' will be implemented to explore whether there are planets outside the solar system that are suitable for human habitation" And some NEW cg (started from 0:50:40): A new node for CSS (it also may be the 'Tianhe-2 Lite') Manned spacecraft and the landing module Landing module on the moon

FT: You're right, but I can make this all three into one: the unspeakable JL-3 using HGV warhead was carried out a seriously lack of transparency exercise. And guess what? This evil thing can even be one of the ABM systems to perform anti-missile missions! That's basically what happened with their 'orbital bomber' report last year.

Apparently, there's something 'rocket' was launched: Many people from northern China photographed a 'strange sight' in the sky. But CNSA, CASIC or CASC's official weibo didn't said anything yet. Video taken from Beijing, Ordos and northwest of Hohhot. And a lucky pilot caught this:

Although it doesn't matter at all, but it was quite a surprise to learn for the first time in 24 years that my birthday had such a coincidence with such a great occasion. Everyday learn something new

Months ago, when I still study abroad and didn't back to China yet, I was bought a spy camera: the Minox C from one of the antique camera shops in London. I also bought a bit of film for it and the tools to cut from the standard 135 film to its special 8×11mm film. And I really try to use it to take some photo during my following museum trip. When I back to where I was living and looking at this little thing, and my iPhone mini, I suddenly realize what's the meaning about 'technological revolution'. Apart from taking photos or videos, and communication functions, its greatest power is its ability to bring information technology at an extremely low cost. But this "very low cost" is more a test of the user's industrial power and the ability to guarantee the supply of information in the place of use. The advantage of having information, not to mention war or not, just few months ago, a terrorist attack was carried out against Chinese people in a hotel where a number of them were staying in a country with an unstable security situation. And by setting up a WeChat group and communicating in real time about the movement of the terrorists, these Chinese people were able to wait safely for the arrival of the security forces and there were no casualties. At the other end of the spectrum, however, are some PLA exercises: the 'red side', which used to be 'invincible', is subjected to 'complex electromagnetic environment' by the exercise directorate - that is, they 'travel back' in time from the 2020s to the 1920s, which made them basically rely on messengers for communication. And, of course, there have been reports of high-tech exercises not far removed from the number of reports of such extreme manoeuvres. Details of the exercises are rarely made public, but the term "complex electromagnetic environment", which often appears in reports of PLA exercises, has basically become some kind meme among Chinese military enthusiasts: it describes the signal lag in phone calls, network lag in games, and lag in some webcasts. btw, the winning percentage of the 'blue side', with its high-tech, highly informative profession, is 32 wins and 1 loss in 33 battles.

The first cube sat deploy from CSS, CAS-10, will be deployed from Mengtian* at 01:30 UTC on 18 Dec, 2022 https://www.amsat.org/camsat-xw-4-cas-10-satellite-to-be-deployed-december-18th/ https://amsat-uk.org/2022/03/20/cas-10-cubesat/ It's the science satellite from Macau University of Science and Technology that was carried by the Tianzhou-5 * Correction: it mounted on the exterior of the transition section between the propulsion and cargo compartments of Tianzhou-5. So logically it should be deployed from Tianzhou-5 directly. Blue words: TZ-5 carries experimental payloads to independently carry out three space science and technology experiments.
