Generally, the current idea is something like the manned module + lunar landing module + Earth-Moon transfer propulsion module. So, I think the "descent stage" on the exhibition is in one use: when it finishes its mission, it will be smashed on the moon. The new "descent stage" we expected is the Earth-Moon transfer propulsion module. The transfer module can back to the LEO and dock with CSS. Re-supply at this point would be simple, just launch a Tianzhou. You can ask google translate to help you with this paper, which is more current as it is from 2021: https://www.fx361.com/page/2021/0709/10846203.shtml

Not a press conference, but an exhibition at the National Museum of China, east of Tiananmen Square. I did think about taking the sleeper high speed train to Beijing with my girlfriend on Friday and then coming home from Beijing on Sunday night, and she: is there something wrong with you? And that museum is the biggest museum in single building I ever been (not "single building" one is north of it, called the Forbidden City): from my experience, it is probably two to three times the size of the British Museum. Yes, I remember there once the CNSA's official statement that the landing module is reusable. The general plan was to launch the manned module and the landing module separately and to dock them in lunar orbit. After the crew has entered the landing module and gone to the Moon, they return to lunar orbit in the landing module entirely. After docking, the crew will return to Earth in the manned module, while the landing module will remain in lunar orbit awaiting the next mission and refuelling. I was thinking that if we could launch a module with multiple docking ports based on this, we would be able to perform more diverse tasks. But considering that CNSA's plan is to build a research station on the lunar surface, and that mankind has no experience in "Which is better? Building a space station in lunar orbit or a research station on the lunar surface?", this question is really worth discussing I think.

This year the PLA's decorations system has been reformed from once representing only time served in the military to a system of wearing medals roughly in line with other countries around the world (FINALLY!). So, we can read the former XSLC commander's "CV" in uniform: Third-Class of Meritorious Servisce Medal, Member of the CMC, 4 times of Individual Recognition 2 times of Third-Class of Commendation Medals, 2 times of Third-Class Outstanding Grassroots Officer Honours, 8 times of Commemorative Medal for Major Military non-War Operation 10 times of Experience in Major Special Assignments, Golden Medal of Guarding the Frontiers, Chief Officer in Corps Level Experience Deputy Officer in Corps Level Experience, Chief Officer in Divisions Level Experience, Experience of the Main Leaders of the CMC Experience of Main Leaders in Theater Commands, Experience of the Main Leaders of the Departments within the Corps Level Organizations, Experience in PLASSF Experience of serving in professional and technical positions at secondary level, Advanced and intermediate Command Education Training Experience Primary Command Education Training Experience, 40 Years of Service, 6 Years of Service (46 years in total) The XSLC is indeed a particularly tough place. As the criteria for the Golden Medal of Guarding the Frontiers, requires service in a remote and difficult area for more than three times the time spent in the corresponding area. The Liangshan Yi Autonomous Prefecture, in which XSLC is located, has always been one of the extremely difficult areas for poverty eradication.

Another Kuaizhou-1A with advertisement incoming. This time is the brand of Baijiu "Jiu Jiang Shuang Zheng (九江双蒸)". It's something 500ml bottle of distilled spirits with an alcohol content of 42° or more can be bought for around 24 RMB. It is more commonly found in the hands of people who have lost their love and are heartbroken.

First, the staff in the CNSA, such as the people in the Beijing Ground Control Center who counting down the launch and answering the astronauts from the astronaut support team answering "Shuguang Copy", are "100% pure civilian". Second, CNSA's subsidiaries are social institutions: they are recruiting fresh university students on job boards. Third, selection of astronauts for the new echelon were open to talent from universities and research institutions: they even recruiting people from Hong Kong. So yeah, to put it mildly, in this field of technological research and development, they are the nerds who never hold a gun. And the PLA has always had subordinate aerospace research department. They merged with the cyber information security department and the information and communication department Space Systems in 2015 to form PLASSF. And, well, mildly again, they are the nerds who can touch a gun. In addition to this part of rocket science, the launch site has a security department, and this is the responsibility of the military. For in the early years there were rumour-like stories about arrests for someone illegal mapping near the launch sites and camouflaged radio devices being placed in the bricks of the old Great Wall. Don't know much about the link between the US military service system and NASA, but I guess the relationship between PLASSF and CNSA is more similar to that between NASA and the US Space Force + US Strategic Command. And it's ok to think CNSA don't "civilian enough", there's commercial company. Their relationship with the military, apart from any orders they may have, is to declare permission to use airspace. The bureaucrats in CN and US don't operate with the same logic or same needs to be met as each other. There is not as intense competition between the PLA services and the different organizations and departments. If there must be competition, it is in many research projects since the 1950s until recent years: often technology is imported from abroad, which is digested and understood under licence for production, while domestic research on the same technology is carried out in parallel in other units in the same industry. Such as in the development of the PLA's missile TEL vehicles. It's not quite clear how CNSA's launch schedule is prioritised. And as I said, it hasn't been more than a decade since this country demonstrated the ability to match its international counterparts in the space sector. The PLA has a lot of current satellite launch needs, but at the same time, there are a large number of local governments in different provinces in China that have satellite use needs such as land planning and environmental protection monitoring. Not to mention the number of university research institutes.

Thinking back the recent years, they really trying to control the dropping area: In the first stage they used a group of grid fins and it was on the CZ-2D in the mission of CHASE. If I remember correctly, one of the fins was reused for second time. Second stage using the de-orbit sails. I don't know if it's considered good news or bad, but the thing that "hello America" over Texas days ago was followed by the remains of at least six five such rockets with de-orbiting sails on the orbit now (if I remember correctly there were more than that. There were three or four more other mission patches without an "ocean background" but shows that they have a sail on the upper stage at the time of those surveillance satellite launched). The fairings they tried to use parachute in 2021 (This is a link in Chinese, but there is a 13 second video of a camera on the fairing capturing the moment the parachute opens) And the dead satellite, they used the Shijian-21 to tow it to the graveyard orbit. You can tell that someone are at least aware of the problem.

Another order from Egypt. The mission patches about Horus-1 and 2 can be combined: via. https://mp.weixin.qq.com/s/tP-VVjYaGnSrY1shWMwlKQ Strange record: in the hours before the launch of the Horus-2, JSLC had four rockets in "upright position": CZ-2C, which sent the Horus-2, Zhuque-2, CZ-2F/G Y16, which was on standby at the VAB for emergency rescue, and CZ-2F/G Y17, which was being assembled.

Botanists in Zhejiang have bred a new variety of Sakura blossom with "Luosifen" (Smells like pickled food and "little stronger". It should be available in the average Asian supermarket and is a strange thing that smells strange but tastes quite tasty). https://tianmunews.com/video.html?id=2418252&duration=88.0&isVertical=1&fsize=25612564&width=720&height=1280&continueFlag=50231596eb15ada56344fb253ccd81b4

Broadly agreed: a more responsible attitude is indeed better for all. That's what includes the installation of de-orbiting sails and the launch of Shijian-21 which attempts to actively capture abandoned satellites made for. But it has not been more than 10 years since this country demonstrated a spaceflight capability that can rival that of the US and Russia. If you travelled back ten years and retold the current CNSA news on the Chinese Internet, people would probably scold you, "What are you daydreaming about?" And if you do some research, you'll find that most of the news of this country's technological advances have taken at least 10 years from "Hey guys, I've got an idea", to the inception of the project, to the actual maturation of the application. Just I know so far that number of other projects that are even longer than that. The current official "ambition" for the future is that they want the rocket to be "use them like a civil airliner". Any tech takes time to develop, just give them some. So, CZ-5B designer, what were you thinking about the core stage re-enter? You'd better really do that!

Hainan Daily: Tianzhou-6 has completed the factory-related work and it's shipping to the Wenchang Spaceport for a planned launch in May this year. By the way, with further exploration of the capacity potential, the Tianzhou, can be take more supplies than before on its way up to the station. Starting from Tianzhou-6, the launch frequency was changed to 3 times in 2 years, instead of every 6 months as in Tianzhou-2~5. And that's also the reason why the mission patches voting for 2023's manned space missions for supply ship only have Tianzhou-6.

CCTV: CNSA will make a project declaration for the heavy rocket project this year. https://view.inews.qq.com/a/20230311V047PZ00 (watch out, English subs not available)

lol. the original link was deleted. Yep.

Different in appearance, in principle and in the needs, they meet: the fuel tanks of the space shuttle are designed to allow it to break through the atmosphere. If you must compare, it's same level to the other rockets first stage. And the Shuttle needs to be in orbit in "months", whereas those ocean surveillance satellites need to be in orbit in "years". Just letting the whole rocket take them to sub-orbital and then relying on the satellite to change orbit on its own to where it needs to be would undoubtedly waste its precious lifetime. And that's the de-orbit sail made for. I'm not familiar with Western companies, but in this country, when a technology proves to be mature and reliable, it's always subject to a 'technology freeze': no fundamental changes are made to the main design, but minor amendments can be made. Adding multiple starts to an engine requires modifications to the engine as well as setting aside a portion of the fuel are clearly not included. And, if you are the leader of CNSA who can decide the design of rockets and here's two options: A: Modify the engines to add a bit of uncertainty to an otherwise exceptionally reliable rocket and set aside some of the fuel to take up otherwise valuable rocket launch capacity to satisfy a demand that leaves the Western media impeccable. B: Don't make such a modification, but by further exploiting the rocket's potential, do what would otherwise require a portion of fuel to be set aside and a modification to the engine to do so by installing a de-orbit sail. And using the wasted mass from option A to carry some heavier payload. There's lots of orders from different organizations including PLASSF, many of the country's local government departments and many universities out there. More efficient, more economical, and more reliable is always the optimal solution. Not words o of praise and put-downs from any media.

1. Shuttle's giant orange tank is significantly different with all the rocket's upper stage. And when the rocket wreckage hits a farmer's property, the amount of compensation CNSA paid by is enough to give the victims "memory loss": Yep, on the Chinese Internet, some of the local residents who are often evacuated by rocket launches will post short videos saying "Gee, how come it didn't hit my house this time? " 2. If we are talking about the first stage "dropping the tank irresponsibly, such as the CZ-5B", I won't argue with anything. At most, I'm really wonder what the designers involved were thinking about at that moment. But don't worry, there should be in some documentary within a decade. 3. If we are talking about the second stage or the final one "dropping irresponsibly, such as CZ-2D this time". So, my answer is that no one in the world can currently land a rocket upper stage under controlled (where controlled is defined as a return like the Falcon 9's first stage), not to mention CN and RU, and even Space X's own rockets have landed in the Americans' own farms many times. 4. Like our friend said that CZ-2D was a rocket developed from those of the mid-1970s. Putting a de-orbit sail on the upper stage is the best it can do. The most significant shortcoming is that the Chinese authorities haven't shouting to tell other countries "Hey hey hey, The man-made meteor shower incoming!" (weird) 5. The siting of US launch sites is fundamentally different from that of China: the US did not need to consider the secrecy and security concerns and then placing launch sites deep in the mountains during the Cold War. But China needs that: both Xichang and Taiyuan were made for this purpose. And people living 50 years ago couldn't have imagined the extent of development in the surrounding area 50 years later. 6. "Development must be used to solve the problems that development brings." We can see plans about the new re-usable rocket and launching at sea. The more responsibly action I think the CNSA are already think and developing about that in a more feasible way. Currently, the CZ-2 and CZ-3 series of rockets are China's most reliable and economical family of rockets. To develop the next generation of alternatives may not be possible without a decade in terms of the objective laws of scientific development.

A song of Muslims in China during the Yuan Dynasty, restored by lovers of ancient Chinese folk music. "In the 14th century AD, when the Moroccan traveller Ibn Battuta was in Hangzhou, he attended a party on a boat trip on the West Lake. The musicians accompanying him played music and sang it in Chinese, Arabic and Persian. The memoirs of Ibn Battuta have preserved, in a fragment, half a verse of a Persian song that he loved and sang repeatedly. The song is actually a quatrain by the Persian poet Saadi." https://www.bilibili.com/video/BV1HR4y1h7d2/?spm_id_from=333.1007.top_right_bar_window_history.content.click&vd_source=6fef304b8d0c4737896e6b702ddfbfb3 "Alone, my heart is tied to you, and I fall into the abyss of longing. As you bow in worship, you appear between the niches."

I agree with the idea of drawing a "danger zone" in another country, or at least a place where other countries can see it and tell them to "watch out, there are artificial meteors incoming" (of course, in the last case of the CZ-5B wreckage, the CNSA officially published the orbital altitude and inclination parameters on its official website every day. But Nelson was still "I can't see it, I can't read it, it's not there" *shrug*). However, if you want a rocket upper stage that has already sent satellites to an altitude around 500 km LEO, with its de-orbiting sails, to crash into exactly 71% of the planet, and it's happened one year and two months later, I generally call that kind of thing 'gamble'. We've all seen the China threat hype of letting rocket wreckage free fall lots of time. And we've seen the strange China threat hype of launching satellites up there to collect rubbish. Now we just don't know what the hype will be about hanging NOTAM in other countries. Except for China, all rocket wrecks fall as "beautiful shooting stars across the night sky." It's not a particularly big deal to pay for damage caused by rocket wreckage if hitting something. Not to mention that the odds of such a thing are not much higher than winning the jackpot. One thing to be reminded of is that there are still lots of rocket upper stages flying in orbit from different countries.

I visited this place when I was very young, and the stereotypical image of this place - Qingyuan - is that a little poor, and underdeveloped place. Of course, it's certainly not like that now. It's some kind tourist area with good natural resources. Rafting in the mountain streams here is a pretty famous tourist attraction.

For China to draw this in another country's airspace, that's really ahead of its time. I have a certain gripe with some of China's publicity departments: they tend to be too conservative, too "in the pursuit of staying out of trouble". I guess their thinking is "don't you have an efficient tracking system of your own, why do you need us to report it?". And then, well, that was it.

Unfortunately, the technology for such a rocket upper stage wreck to make it burn under controlled is still something little too far ahead for humans in 2023. the upper stage of the CZ-2D rocket is not very big - not like something CZ-5B - it is a high 10.9m canister 3.35m in diameter: it's not much bigger than the Falcon 9's second stage. The best and most efficient way to deal with it at this moment is to keep it in orbit for as short as possible. And it did. To be honest, I could tell from the title of this article what the content would be about, what quotes would be from whom, and what conclusions would be drawn... And it really wrote that.

CMS conducted a voting campaign for the patches to the manned space mission in 2023, which the Shenzhou-16 and 17, and the Tianzhou-6: http://www.cmse.gov.cn/hdjl/bszjhd/tptd/202303/t20230308_53039.html Because the designs are all pretty good to me, I simply don't know which I should vote for

Stupid question: had any rockets before like that or even little crazier than this one? I think it shouldn't be the first one and definitely won't be the last one
