Bad news, or worst news: The Chinese paddlefish, one of world's largest fish, has gone extinct There is a documentary about a national animal protection unit that has been set up in a not insignificant area of the Yangtze River basin to conserve and breed these endangered freshwater fish. They did try to breed the Chinese paddlefish here. But unfortunately, this effort failed due to the low survival rate of the fish's low fertility. Fortunately, however, the Yangtze River endangered fish such as the Yangtze swordfish and porpoise that they tried to save here were gradually bred and gradually released back into the Yangtze River.

Yes indeed. And the original CCTV’s report makes me feels like there will be upgrades for it in the future. So it would be using the same orbit with the station and floating around it. And dock with the station if it need. Meanwhile it probably would be the first telescope that can refuel in space hahaha

And, if everything goes well, Wentian will be launched around 14:20 (UTC+8) at this Sunday. I checked the weather forecast. The weather in Wenchang on that day will be sunny from 27 to 31°C with a 20% chance of rain attached. If it doesn't rain, this will be a wonderful day for a typical tropical beach.

Read an article named Some Thoughts about Cislunar Exploration and Exploitation from Journal of Astronautics (《地月空间探索与开发的思考》), write by Bao Weimin, the director of CASC, and Wang Xiaowei, professor at Beijing University of Aeronautics and Astronautics. But this article is fully Chinese. In this article the outlook for the development of spaceflight on the Earth and Moon is mentioned. "... The future of space transportation in Earth-Moon space is bound to be flight-oriented and will require the following capability requirements. 1. Access to space-carrying capacity: single-entry space capacity to break through the 100-ton class and access to space on a scale of 10,000 tons/year. 2. Space transfer capacity: to support the realisation of large-scale lunar and asteroid exploration, with the scale of orbital transfer reaching several thousand tons/year. 3. Reliability, safety: cargo flight reliability not less than 0.995, manned flight safety not less than 0.9999. 4. Launch costs: launch costs per unit payload down 1~2 levels from current, single carrier use up to 100 times. 5. Launch frequency: a significant increase in the scale and type of access to space, with a launch frequency of 1,000 sub/year." The industrial systems of cislunar exploration and exploitation includes: Basic Industries: Transport (including launch sites) Measurement and control In-orbit service and maintenance Space monitoring and early warning Space Weather Services Space life support Dominant Industries: Application Industries Communication, navigation, remote sensing Space exploration and testing Space Science and Technology Experimentation Services Space energy conversion and utilization Space tourism Space security Development and Utilization Industries Space Power Space Mining Space agriculture Space manufacturing Space medicine Expanding Industries: Insurance Education and Training Science industry Finance Entertainment Culture Tourism etc. And "4.3 Development routes. It is expected that around the middle of this century, the Earth-Moon space transportation, resource exploration and development drink infrastructure system will be fully completed, the legal and regulatory system will be perfected, a low-cost and highly reliable Earth-Moon space flight-based transportation capability, an efficient space resource development and utilization capability, and a frontier space science exploration capability will be fully formed, and it will be in the world in terms of original frontier scientific discoveries, major key technologies and major engineering achievements The new industry of the Earth-Moon space will be fully formed, the output value will reach RMB 100 billion, the industrial and economic structure will be reshaped, breakthroughs in scientific and technological innovation will be made, and the overall world view of the Chinese people will be greatly changed. In the near future, it will complete the key technology research and development of flight-oriented space transportation, remote sensing resource exploration around the Moon and lunar polar regions, and start the construction of three major software and hardware systems; the initial construction of a legal and regulatory system, based on the Space Law, linear designation of laws in areas such as commercial space management, and raising the legal ranking of prior approaches; the scientific progression of the Moon from global census to local detailed investigation and then to laboratory analysis of samples; and the formation of some basic industries such as transportation, measurement and control, space detection and warning. In the medium term, the construction of the three major hardware facilities will be basically completed and initially operated, and core capabilities will be formed; the legal and regulatory system will be basically perfected, with complete supporting laws for space safety, spacecraft operation in orbit and space activity management; breakthroughs will be made in research on the origin and evolution of the Moon and the coupling of the Sun-Earth-Moon space environment, and a multi-station linkage exploration of the 'Lunar south pole main research station + frontal substation + back substation' will be realised; basic industries will be fully formed, leading industries and expansion industries will be basically formed, and the Earth-Moon space economic zone will be initially built. In the long term, the construction of the three major hard facilities will be fully completed, and the low-cost and highly reliable Earth-Moon space flight-based transportation capacity and efficient space resource development and utilisation capacity will be fully formed; the legal and regulatory system will be complete, and the needs of the Earth-Moon space industry will be fully and effectively guaranteed; the main and sub-stations of the completed research stations will be used to establish an interactive detection network; the industrial chain will be closed and the Earth-Moon space economic zone will be fully established, and various types of deeper space exploration activities will continue to increase with Earth-Moon space as the base." First building the ships and then setting up camps in Antarctica. With the development of technology, it makes it both easier and more profitable for ordinary people to travel to Antarctica at the same time. It's not unreasonable that mankind could reach this level of scientific and technological development 100 years or more later. Considering that from the time when the adventurers explored the Antarctic 100 years ago to the time when ordinary people can travel there and even start a wedding more than 100 years later. There was a video blogger on the Chinese internet who managed to "propose at the North Pole and get married at the South Pole". Let's hope that in a hundred years' time someone will be able to "propose on the moon and get married on Mars"

Do some little research and I find this: Notification of emergency evacuation of rocket wreckage. Can't find the full version now. (via. Weibo) Translate: A satellite launch mission will take place on 13 July 2022 between 00:19 and 00:39 (Tuesday evening). According to the instructions from the higher level, our Shuikou Township belongs to the scope of this satellite launch wreckage landing area, in order to successfully complete this recovery mission and ensure the safety of people's lives and property, we hereby notify the relevant matters as follows. 1. Each village must finish village and group cadres meeting before July 12, 17:00, each group should finish meeting of heads of households, and should finished the publicity. Make every household knows, everyone knows.... Try to search something wreckage video from Tiktok and Kwai. Apart from other videos of the rocket wreckage from a year and two years ago, I could only find video footage published two days ago of traffic police closing roads in a 30km radius.

Tianzhou-3 has left the space station and it would be de-orbit in few days later. It has been in orbit for 302 days since 20 Sep. last year. If we really have looking for a pattern, the length of time in orbit for the Tianzhou-2 was 305 days. Meanwhile, the Wentian module with CZ-5B rocket has transferred to the launch site The mission patch: And Mengtian module completed thermal vacuum tests A comparison of Core module, Wentian and Mengtian: At least this quadrant of the Mengtian in the picture looks quite "neat".

Remember the conjecture that the middle ear evolved from the gills of fish? We now have fossil evidence! https://www.frontiersin.org/articles/10.3389/fevo.2022.887172/full But... it would be nice if this organ could be kept free of inflammation.

For physically something two characters is enough. In fact the very first moment my thought was Xihe (羲和) or Kuafu (夸父). One is the ancient legendary sun goddess, while the other is a giant who chased the sun and killed himself. But Xihe was already named for the Chinese H-alpha Solar Explorer, and Kuafu was already named for the Kuafu project. The rest of the ancient Chinese legend I know about the sun is that of a man called Hou Yi, who "shot down nine of the ten suns in the sky". But considering that he was Chang'e's husband, I would like to save that name for the manned mission to the moon. There has been so much ancient literature over thousands of years that who knows there have how many better names than this. As far as I can see, the names given by people on the Chinese internet, apart from some jokes, are basically Xihe and Kuafu. But I notice two other: Jin Wu (金乌) and Zhu Zhao(烛照). Jin Wu, aka the "three-legged crow". And Zhu Zhao, the lexical meaning is "the light of a candle shining on something, as a metaphor for the bright and beautiful future of that thing". It's not impossible if you really have to connect it to mythology, although it's also a divine creature related to the sun, but it's a modern novel. For the ships, the navy's ship has their own rules for how to name them: use the place names. Basically, nearly all cities' names are two Chinese characters (few of them are three), except for some of the names of ethnic minority areas which are little longer (about four to six characters) due to their phonetic transliteration. In the case of civilian vessels such as fishing boats, their name is made up of the abbreviation of their local fishing affiliation (usually three characters) plus a serial number. Objectively speaking, Chinese characters are an extremely informative script, and two characters are really enough for a name.

Is there a possibility that all these nicknames for the CNSA's are all with two Chinese characters plus the serial number (if needed)? [snip]

Yeah, I know. But personally, I really don't like any kinds of insect. So... A new episode of Tiangong TV Northwestern Polytechnical University’s ASN218 drone has completed a landing on board experiment. Chang'e 4 and Yutu 2 rover has finished the 44th Lunar day. Now both lander and rover are entering the sleep mode for the 44th Lunar night. The Yutu 2 rover's route of previous 44th Lunar day: Yutu 2 rover also help the scientist write this: Radiative Transfer Modeling of Chang'e-4 Spectroscopic Observations and Interpretation of the South Pole-Aitken Compositional Anomaly

All right enough joke. The Advanced Space-based Solar Observatory has opened a call for the nicknames (but in Chinese) to the society. To be honest, I'm not particularly good at ancient Chinese literature, so I didn't come up with any particularly "heat-resistant" names with a 'Chinese cultural flavour'. The space debris detection payloads which mounted on the Tianzhou-3 cargo ship has already acquired thousands of images in orbit. Chongqing will build a nickname called "China's compound eye" (sounds weird to me), the "Super Large Distributed Aperture Radar High Resolution Deep Space Active Observation Facility" is start of construction. It will be the world's longest-range radar, with an observation range of 150 million kilometres. A prediction: we will hear some news about Wentian module this week. Probably would be a picture closing the fairing.

ARRC (Advanced Rocket Research Center at National Yang Ming Chiao Tung University) has successfully launched 'the First Satellite Carrier Like Rocket from Taiwan'. Flying at an altitude of about 3km and dropping in the sea two minutes later. The original scheduled flight time of the rocket was eight minutes and an altitude of 12 km. And Shih-Sin Wei (魏世昕), the deputy director of ARRC still claim that it was "99.9% successfully launch". "Well... alright... if you say so"

Miss this one. According to the Wiki it takes two secondary payloads from Copenhagen Suborbitals and another one was a briefcase-sized probe from Luxspace made in German. So, congratulations, Luxembourg, you are the eighth which make it to the moon

Xuyang-15 cargo ship has arrived in Tianjin port. From the planned launch of "Wentian" this month and the arrival of the cargo ship in Tianjin in April for the transhipment mission, it makes sense that "Mengtian", which is planned to be launched in October, would arrive in Tianjin at this time. Deep Blue Aerospace (深蓝航天)'s 20 tonne thrust Thunder Reusable 1 engine has finished it's first test run. It tested five times and the engine accumulated run for 138 seconds. Longest single working time up to 90 seconds. Seems like we are going to have a new VAB at Wenchang launch centre in Hainan And just a short distance to the southwest, construction has begun on China's first commercial space launch site. Embassy of China in Algeria launched a "talk with taikonauts" campaign. But somehow, I have a felling it might not work pretty well...

When I revisited my phone album, I found these pictures taken during my trip to Beijing on 2018: Clothes and boots worn by Jing Haipeng, the crew of Shenzhou-7,9 and 11. This is the one worn on his Shenzhou-11 mission and collected by the Military Museum of the Chinese People's Revolution. And the flag waved during the first Chinese EVA mission by Zhai Zhigang. The National Museum of China collect this. Have to say the flag is much thicker than I expected.

Forgot to attach the original video Considering they are the unit at Tibet and based on my personal experience. The attitude where they were training in some clips must be around 4500m or more: no trees and taller vegetation. Strongly advice don't run like them when you firstly visit there within one month. Don't ask how I know that

PAP (Chinese People's Armed Police Force) have a training site called "Ice World"

A successful launch of the 'Feitian-1 (飞天一号, Flying-1)' rocket ram-combined power rocket led by the Northwest Polytechnic University's School of Aerospace's Air-Sky Combined Power team. "For the first time in the international arena, the kerosene-fuelled rocket ramjet combined cycle engine has verified the smooth multimodal transition and wide-area integration capability of rocket/sub combustion, sub combustion, super combustion and rocket/super combustion, and has broken through key technologies such as thermal throat adjustment and efficient combustion organization of ultra-wide cladding lines, and the flight test was a success." (Original source)

Now I see why there have something sail like thing in the patch: CZ-2D Y64 rocket's loading component has deployed the biggest deorbit sail ever in China. In the fully unfurled state, the sail has an area of 25m². The sail tests on the ground: "Without de-orbiting measures, a satellite of the 15kg class at an altitude of 700km would remain in orbit for 120 years or more at the end of its life; with a de-orbiting sail of 2m², the time in orbit could be reduced to less than 10 years." Original source Chinese want to occupy the moon... again Don't know is NASA having something trouble on getting funding these days, or just simply their boss has smoked something up again since his "takes two to tango". Anyway, I don't want to comment anything based on respect for the rules of this forum.

CZ-5 Y6 rocket's first stage engine, and CZ-5 Y7 rocket's second stage engine was completed 'ground calibration test run.' In term of the current schedule, they are the engines for launching the Chang-e 6 and 7 around 2024. "These engines will be subjected to high altitude simulation tests to obtain vacuum thrust performance parameters. If the engine functions and performance parameters meet the overall technical requirements of the rocket, it will be delivered for assembly."

Another comment below: someone visit the Spacety years before. And Spacety's CEO show him a video of Earth taken from 500km high. He let that guy guess how much of this camera was. That guy: that's rocket science, hundred thousand RMB perhaps? Spacety's CEO: nah, 42 RMB (2.5rmb you can get a can of coke in China)

Spacety (天仪研究院) was published an article about their satellite completing its deorbit test and re-entering the atmosphere. And they attached a photo with the article: People comment below: Wait? Are you just use a tape measure for antenna? Yang Feng, Spacety's CEO: Yep, it's the most common tape measure you know. It used to be that such things were made of memory alloy, but then we somehow found that tape measure also worked quite well. Another comment: Can these survive more than 24 hours? Yang Feng: The longest-lived satellite we've had is three years and nine months. And now it's entire system still stable, happy with that? Damn that's one of the coolest and most economical things I ever know

I think is to vertify some theories or assumptions calculated by the experts on ground to see "what happen if we let it brake in the Mars outer atmospher?". I think that more likely to be CNSA's experts want to have the data by themselves instead of the foreign data. After all, the rover on Mars now is sleeping to avoid the dangerous situation in Mars winter. The rover can't do anything for several months, and the orbiter was finished every missions, so why not... Speaking of data, Tianwen-1 orbiter has finished all the established scientific exploration missions. In this two years flying around Mars, Tianwen and Zhurong has send back 1040 GB raw science data to Earth. Several new photos from Mars: Ascraeus Mons, shot by Tianwen's medium resolution camera: The Mars' antarctic ice cap The west part of the Valles Marineris The impact craters in Arabia Terra The edge of Maunder Crater shot by the Tianwen's high resolution camera. The lower left of the picture shows the interior of the ring pit, with the rim of the pit visible as a clear collapse into the pit. And a small sand dunes taken by the Zhurong rover before it enter the sleep mode

CZ-4C Y46 rocket successfully launched the Gaofen (High Resolution)-12 03 satellite into orbit. The chief designer of the Tianwen-1 orbiter and Zhurong Mars rover, Sun Zezhou said that will be planned a test mission for the Tianwen-1 orbiter: atmopheric braking. It will make the perigee perimartian of the orbit to 50 km. I think it's to gain some experience for the Tianwen-3 mission. "What's the most difficult thing to do in space?" "The hardest and most tiring thing to do in space, and things that aren't always done well, is to cut your toenails!" Zhai Zhigang, captain of the Shenzhou-13 crew speaking at the first press conference back to Earth. "First, the foot hardly be retracted, you have to wrench the foot. Secondly, you can't let the toenail fly around, so you have to catch it after you cut it immediately. Then vacuum it up."

Looks like the Shenzhou-14 crew has cleaned and tidied up the room now: 00:16: they are unboxing a new grapple fixture for the robotic arm! In terms of the schedule, the Tianzhou-3 cargo ship probably will leave the station in couple of weeks. And leaves the forward docking port for the Wentian module.
