Something about the future Lunar discovery project: The plan that takes a new Earth-Moon relay satellite with Chang'e 7 has been cancelled. Instead, it was planned to launch it alone. We make some handshakes with Emirates, and we would take a small rover from them on the Chang'e 7 And hello, solar system: Tianwen-2, the asteroid exploration mission is expected to be carried out in 2025. It will detect asteroid HO3. First, it will take about a year for the transfer and rendezvous. After a year of close orbit exploration, asteroid sampling will be conducted and the samples will be put into the returnee. It takes half a year to return to the Earth and "throw" the returnee back to the Earth, and then it will enter into the comet transfer orbit for about seven years. Seven years later, it will rendezvous with Comet 311P in the main belt and perform the comet orbit detection mission. Tianwen-3, the Mars sampling return mission is expected to be carried out in 2028. The Tianwen-3 detector system is composed of two major parts: the orbit return assembly (orbiter+returner) and the landing assembly (cruise stage+lander+launcher), both of which are launched by Long March 5. Tianwen-4, the Jupiter System and Planetary Crossing Exploration Mission. It will use Venus and the Earth to carry out three "gravitational slingshot" effects. In other words, there will be a chance to see Venus. On the way to Jupiter, the asteroid leap exploration will be carried out. When approaching Jupiter, the Leap detector will be separated from the main detector, and the Leap detector will perform the leap detection of Neptune. The main probe will perform Jupiter's orbit detection after being captured by Jupiter. At the same time, it will use Jupiter's gravitational slingshot effect several times to go to Callisto and perform the orbiting exploration mission of Callisto. The last one is the Neptune exploration mission that is still being demonstrated. It also will be carried out the asteroid leap exploration and use Jupiter's gravitational slingshot to go to Neptune. It will perform atmospheric exploration of Neptune and penetrating exploration of Triton. The umbrella-like thing in front may be some kind of reactor I think. And btw, Happy Birthday PRC! I think it is more like the An-225 but it has rocket engines and shuttle-like things are lot littler than the Buran. I really want to tell you what it would look like but... you know... The "little X-47-like bad boy" has pictures of its fairings and rocket wreckage and we can guess the general outline. But this... man, it even doesn't use rocket!

News from CSS these days: The Shenzhou-14 crew has finished two EVA missions in 6 hours 7 minutes and 4 hours 24 minutes. The good news is, the cover of middle school students' physics textbooks can be updated now: Hours ago, the CSS was like: The indexing robotic arm works, and it works pretty well: People asked, "would we take the EVA suit cover which has the crew's signatures back to home?", the answer from CNSA was "yes, it's in one of our plans." According to the navigation warning, the next new module "Mengtian" will be launched on October 31

Ah my computer finally arrived home from the UK, I hate customs clearance procedures News since August: Yaogan(Remote Sensing)-35 satellites has successfully launched 9 satellites in 3 groups: Yaogan-35 Y66, Y67 and Y68. According to the badges, every end stage of the CZ-2Ds which launch Yaogan-35 all have de-orbit sails: CZ-2D Y75 rocket launched Beijing-3B satellite into orbit. This satellite is mainly used to provide telemetry data services in the fields of land and resources management, agricultural resources survey, ecological environment monitoring and urban comprehensive application. The reason why the badge is designed like this is that the launch time is close to the Mid-Autumn Festival. CZ-6 Y10 rocket successfully launched 16 commercial satellites into SSO on August 10. These satellites are used in commercial remote sensing, atmospheric imaging, and other fields. And Y11 rocket successfully sent Shiyan-16 A/B and Shiyan-17 satellites into the designed orbit. This one is mainly used in land census, urban planning, disaster prevention and mitigation and other fields. CZ-7 Y5 rocket successfully launched Chinasat-1E satellite. But actually, this satellite is more likely to be an order from PLASSF... (The picture is from PLASSF's official Weibo) -"The satellite is mainly used to provide users with high-quality voice, data, radio and television transmission services." -"The function looks pretty civil, but there is something wrong with this account who posted that..." Kuaizhou-1A rocket launched the Chuangxin(创新,Innovation)-16 satellite into orbit at August 23 in Xichang Satellite Launch Center. This satellite mainly used for scientific test and new technology verification (translate: I don't suggest you ask question) The commercial companies: Galactic Energy (星河动力)'s CERES-1 (谷神星-1) Y3 rocket successfully launched Taijing(泰景)-1 01/02 satellites and Donghai(东海, East China Sea)-1 satellite into planned orbit. Taijing is mainly used to provide commercial remote sensing services. And Donghai is for verify the multi-mode remote sensing detection technology of micro polarized light camera. The Zhuque rocket from Landspace seems like have some progress: It is said that it may complete its debut show around the end of October. Something excited: “On August 26, the reusable flight test of the lift suborbital launch vehicle independently developed by the First Institute of China Aerospace Science and Technology Corporation was a complete success. After health inspection and maintenance, the launch vehicle used in the flight test ignited and took off vertically at Jiuquan Satellite Launch Center again, completed the suborbital flight according to the set procedures, and landed stably and horizontally at Alxa Right Banner Airport, successfully realizing the first repeated flight of China's suborbital launch vehicle. The success of this flight test has strongly promoted the leap forward development of China's space transportation technology from one-time use to reuse” (Via. CASC) Simply put: this is the launch vehicle which will send the small space shuttle launched in early August (and this bad boy is still in orbit now). In fact, I'm more curious about which of these two things has a higher level of confidentiality. Perhaps similar to submarines and torpedoes: boats are secret, bombs are top secret.

Well: But honestly this kind of thing actually does happen. And it probably depends on how strict your definition of a private space company is: The orange word "DouYu"(斗鱼) is a live streaming platform like Twitch. And you think there are not enough sponsors for rockets? Try this one: The blue words “长安欧尚” is a car brand. They sell cars and SUVs for under 200,000 RMB (personally I don't like this brand). The small logos on top are the banks and venture capital companies. In fact, even if you are not a private company, it isn't impossible to do such things: The little blue words “安溪铁观音” is a tea brand. I tried it these days when I finally got back home from the UK and it's not bad at all!

Months ago the PLA used the Y-20s to do the humanitarian aid in Afghanistan. When I watch something about IL-76, I always thinking would there had something happened like this in Afghanistan airport: an elder ground staff who was already served the planes from the Soviet and the US, and a rookie. One morning, the rookie: wake up, master! Looks like the American is back! The elder: shut up rookie, must be the Russian! I don’t even need to see it, just hear the sound of engines! Few minutes later, when the plane finally touched down, both of them: ???

Damn, someone's offer was higher than mine and now the price is higher than the historical price I checked, the coin is off the table History always crazy. And share a kind of "coin" that I personally think is cool and a bit crazy: Knife Money. Unlike something trash made by clay, this kind of money really comes from thousands of years ago: simply put, it was same period with the Art of War. Actually, I'm thinking would there been an ancient Chinese version Jack the Ripper and his murder weapon is that...

Fun fact I newly learned: in Chinese history, here used to have some coins made by clay. And they weren't something from a hundred or thousand years ago: They were made in pseudo-Manchukuo in 1945 (but the year on this coin is 1946). Reason why I found that is I had just stumbled into an online auction of ancient coins within China. Bidding starts at one yuan. Somehow I kinda want to buy this

I agree with that. And I think those stone probably can sell for a good price hahaha The one more thing I found that is cool is the dump trucks have all been replaced with purely electric vehicles. Otherwise, I guess the noise should be a bit more louder.

The reason why I have such a question: I finally back home and my mother said that have you seen someone can cut the rocks like cutting the tofu? Me: ? "Ok, fine..." Here used to be a community consisting of some Chinese version of the "Khrushchev House" and is for the employees of a state-owned company. And what they are planning is going to build three 44 to 46-storey flats to compensate the residents who originally owned properties here. An apartment building, an office building and hotel of about the same height, and five commercial buildings that should also be about the same height. Sincere thanks to the soundproof windows. Shenzhen is a city founded in the 1970s and 1980s, and now I know how to answer the question "What is your city's specialty": does site noise count?

Weird question: if someone wants to demolish some buildings and build a new one on the same site, how to deal with the foundations of the old one?

The small robotic arm finished its first test: We can see the grapple fixture for the small robotic arm is significantly different with the bigger one. I read an article (but it has paywall) said this is for a more softly capture and more precise operations. The one of the experiment racks in Wentian, has plant some dwarf rice - Xiao Wei (小薇) at the Life & Ecology Rack. This variety of rice is around 20 cm and goes up to 30 cm. Compared to conventional rice, it's of a more suitable size for growing in the space station. Today is the seventh day of the seventh month of the lunar calendar, the Qixi Festival, which is perfect for launching rockets. Various kinds of rockets. At morning we have the Go Mang (句芒) terrestrial ecosystem carbon monitoring satellite by CZ-4 Y40 rocket. Meanwhile it also carrying the Minhang Shaonian Xing (闵行少年星, Minhang Youth satellite) and Jiaotong-4 Xing (交通四号星, Traffic-4 satellite) I like the mission patch for this one: And we have another "Strongly suggest you don't ask question" object launch by CZ-2F in Jiuquan [snip]

We have a Chinese version of space station filming now Given that the I quadrant is the airlock which once officially reported that it would always be pointed to the ground. This probably shows that the "sloping square thing" may have some kind of unfolding. But still, there's no one come out and introduce what's this to us.

Hard, really hard. Let's assume that one day suddenly whole Europe, North America, RU, and CN use green power and fusion. No offence I basically don't believe that some countries in Africa, South Asia and countries in Central America could afford to use this. What about them? There are billions of people here too

Unfortunately ‘Trolley Problem’ is everywhere KSP logic: do what you said as well. Give Tianzhou-3 a larger tank for refuel the Wentian module when it docked with the core module (Both front and rear docking port of core module all have ability to refuel). Let Tianzhou-3 docking at rear docking port and let Tianzhou-4 flying with the station. When Wentian docked, refuel it and let Tianzhou-3 leave the station. Then put the Tianzhou-4 back to the rear port. Or even just simply launch another Tianzhou only for refuel the Wentian and Mengtian. But the reality is that Tianzhou-2,3,4 and 5 are all in same batch and same assembly line product. The only difference on Tianzhou-2 is it had a grapple fixture for the robotic arm testing. And meanwhile, we have the problem that we all struggle with: the budget and deadline.

Weird, I can open it from my pc chrome in UK but here it is: Except of the engine, you need to think about the size of the station module my friend: they are pretty long and heavy: core module is 16.6m, Wentian and Mengtian is 17.9m. With 22.5 tones for the core module and 23.2 for the Wentian. As a comparison, the length about Shijian-20 launched by CZ-5 Y3 rocket to GTO was 8m and 8 tones. (CZ-5 & CZ-5B) If we put one more stage at middle of the CZ-5B, it will certainly have a significant impact on the rocket's centre of gravity and mass. The budget and time given for the project is limited, and if there is an impact, then the time and money for the corresponding design justification will have to be extended and invested next. Besides the second launch was failure makes whole project delay for nine hundred days. "So, guys, why not...?" Core stage: 33.16m + Second stage:11.54m + CZ-5B version fairing: 20m=64.7m: We are 7.73m higher than the original design. Put everything about physics aside, this even required corresponding modifications to the interior of the VAB and the launch side - just for this one model.

CCTV reported on some of the "hiccups" in the development of the CZ-5 rocket: footage of the rocket's engine exploding https://www.bilibili.com/video/BV1SS4y1t72Y?vd_source=6fef304b8d0c4737896e6b702ddfbfb3 Fast forward to 05:27. What the presenter said at this point: What we are looking at is one of the test runs where the engine, which had just been developed, exploded just after ignition. During the early stages of the development of the liquid oxygen/kerosene engine, there were four explosions, including this one. Ge Lihu, the engine's chief designer: all of them blew up in a fraction of a second, and afterwards we couldn't even find a single "corpse" of the parts from the engine: we couldn't find out where it had gone. So, it was exceedingly difficult for us to analyse the test. Once you have found the "corpse" of the part, you can look at the friction marks, or where it was touched, or where it was hit, and you can analyse and deduce the corresponding conclusions. If you can't even find the "corpse", where can you start to analyse? As a chief designer, I exclaimed at that time that this engine was so difficult, how could I explain it?

"I can't read Chinese, I never hear about it, so it never happened" CNSA's official statement from the official website: *Announcement I, II & III about the CZ-5B Y3 rocket wreckage*

According to the previously CCTV's documentaries, they use aluminium for the tank. Now a day has passed, and I personally haven't seen any videos from the Philippines. Then maybe we'll have to wait a few years for someone to go diving to see it hahaha

It's daylight in the Philippines now and within a few hours there should be video or photos about the wreckage that landed, if any.

CMS official Weibo: At 00:55 Beijing time on 31 July 2022, the remnants of the upper stage of the CZ-5B Y3 rocket have re-entered the atmosphere. The landing area is in the sea around 119.0°E, 9.1°N, and most of the wreckage was destroyed by ablation during the re-entry process. I measured about 58 to 60km or so from the nearest land.

Cool! Looks like a Chinese character ‘土’ flying in the sky hahaha

CZ-2D rocket successfully launched a new group of three Yaogan (遥感, Remote Sensing)-35 satellites from Xichang launch center. According to the mission patch, seems like we have a de-orbit sail again on the upper stage:

We have some progress on the CZ-5 DY. The original Chinese news: "...This test is an important test to verify the key technology of the new generation of manned launch vehicle with multi-engine parallel connection and force transfer under the tank, and is an iconic work to transfer the model to the engineering development stage..." And Chinese forum starting guessing about “What’s this sloping square thing?” At right of the solar arrays. Some guessed a hanging point for large payloads, some guessed a deployable structure, and others guessed a flaw detector.
