  1. Well probably the boss of them wants to build their brand in really special way - by being several times better than the national standard lol Their ultra-pure water tastes very similar to distilled water. Very little bit sweeter probably.
  2. There is a company in China that produces beverages called Wahaha. While they have quite a lot of other beverages that sell well in the market, one of their products - purified water - is quite outrageous. Its electrical conductivity is only 1.56. The Department of Chemistry at Tsinghua University has tested this water, and the result is that this stuff is also at a completely pure level in the chromatographic purity test. How much is it? Case of 12 bottles, 596ml, 12.9 RMB. What is the result of this? Many laboratories in different subject areas that require the use of purified water are using this bottled water that can be purchased in supermarkets. (As a comparison of purchasing power, 500ml of Coke sells for 3.5RMB)
  3. The cost of mining and smelting in space and bringing it back to Earth is nothing less than finding a place to mine on Earth. This is especially true for countries like China, which is particularly rich in rare earth resources and has a particularly mature rare earth resource processing industry chain. The only mineral that might be fair value for cost, I think, would be Helium-3. But according to Wiki, although He-3 is richer than Earth. But there still needs at least 150t of regolith to get 1g of it. Speaking of mining, meanwhile, CNSA is soliciting lunar surface science payload programs:
  4. My gf just played FF7 remake on my PS4. And she just proceeded to the episode where Cloud and Aerith take an evening walk.
  5. The main engine of the manned moon rocket CZ-10 has completed another ignition test run: https://weibo.com/2656274875/NbaeN0olz
  6. More than that, "Lingxi-03 is a flat-panel stacked satellite installed with flexible solar arrays and active thermally controlled fluid loops. It's the first Chinese satellite to use flexible solar arrays. And is also the technical verification of China's in-orbit launch technology for multiple satellite stacking. It will provide support for the rapid deployment of China's future superstar low-orbit communications satellite constellation.", China Space News said. The CCTV journalists visited the company who produced Lingxi-03. On his left hand is the rigid solar panel and right hand is the flexible one. The chief designer said that the whole solar array would fold 12 times but thanks to its thinness, the whole satellite stacks up to no more than 30cm. (The video link, but English subs are unavailable) Meanwhile, this launch also put on the grid fins to control the wreckage drop zone once again.
  7. Lemon Tree is the first English song that many Chinese children will sing and remember.
  8. The engineers who were clapping hands at 0:41 are the astronaut ground support team. Radio call sign "Shuguang (曙光)"
  9. HR team: we get a new freshman for your group. She just graduated from studying in New Zealand. Alright, our group can form two rounds of "Five Eyes" next week...
  10. CMS: "At 21:40 CST on 20 July 2023, after about 8 hours of EVA, Shenzhou-16 astronauts Jing Haipeng, Zhu Yangzhu, and Gui Haichao worked closely together, with the support of the CSS's robotic arm, completed all the established tasks for the EVA mission. Jing Haipeng and Zhu Yangzhu returned safely to the station's WT module. During this EVA, the astronauts completed the installation and lifted the support for the panoramic camera B on the core module, unlocking and lifting the panoramic camera A and B at the MT module. The entire process was smooth and successful. Jing Haipeng, who has gone to space four times, has fulfilled his dream of space walk with 15 years since the Shenzhou-7 mission. Zhu Yangzhu has become the first space flight engineer in China to finish the EVA mission. According to the plan, the crew will subsequently carry out a large number of space science experiments and participate in the completion of the number of application payload installation missions." My little stats can be updated
  11. An electromagnetic ejection microgravity experimental setup. Original link: https://weibo.com/7796311117/NaC9rgnsX "In terms of experimental efficiency, the traditional drop tower can only do 2-3 experiments per day on average, and the parabolic aircraft can fly more than 30 trips each time, but the experimental preparation cycle is about 2-3 months. This device can achieve a frequency of hundreds of experiments per day, with a preparation time of 1-2 days, which improves the efficiency of scientific experiments. In terms of the strength requirements of the experimental load, the traditional drop tower in the landing recovery phase, the test module, and the experimental load to withstand the impact of about 20G, largely limiting the use of conventional scientific instruments. In this device, the experimental module subjected to the electromagnetic driving force is controlled throughout the whole process, whether it is microgravity, lunar gravity, or Martian gravity simulation experiments. The experimental module's recovery acceleration can be controlled at about 3G - so conventional scientific instruments can be used for experiments. In terms of operating costs, the device adopts energy storage and electromagnetic drive technology, and only consumes electric energy for its operation, with a single experiment consuming only about 1 kWh of electric energy, which is low in operating costs and convenient for carrying out large-scale scientific experiments." 2-3 experiments per day by traditional drop tower before... wait did you guys send someone to bring the stuff to climb up the tower?
  12. In early Shenzhou missions, they brought pumpkin seeds up there. Then our city, being in the hot south - a great place for plant breeding - has a sizeable "space plant breeding greenhouses". The school organized a visit there when I was in primary school. I swear those plants are the strangest looking I've ever seen till now: it's still a bit of a shock about 200kg of real pumpkin in front of a bunch of kids less than 10 years old.
  13. CMS: Publication of the list of space breeding experiment projects for the Shenzhou-16 spacecraft "CMS organized experts to evaluate the declared projects and selected 136 copies of space breeding experimental materials from 53 institutions were selected on board. These included 47 agricultural crops (12 seeds of food crops, 28 seeds of cash crops, and 7 saline-tolerant plants); 76 forest herbaceous, floral, and medicinal plants (17 forest trees, 21 forages, 7 flowers, and 31 medicinal plants); and 13 microorganisms and other species (2 agricultural microbial strains, 3 industrial microbial strains, 3 edible mushrooms, and 5 species of algae and mosses)." I take a look at the list attached. It basically covers everything you can buy in the supermarket that you can eat: from grains such as rice, wheat, maize, and buckwheat, to fruits such as pears, grapes, raspberries, and passion fruit. From cash crops such as peppers, oilseeds, peas, and tomatoes to forages such as alfalfa, cattails, camel thorns, and white sorghum. Microorganisms include bacillus, human gut bacteria, probiotics, lactobacilli, and aromatic bacteria. add: At the end of the announcement there is another sentence: "Plants carried by manned spaceflight is a public service - it doesn't charge any fees for this. Any organizations or individuals are prohibited from using this for false propaganda and commercial speculation." Well, a decade ago, the early Shenzhou missions also bring many seeds into space. And then those in the market that are unusual in appearance, size, or color are given the prefix "space"... "Do you really believe in the things you write on your signboard?"
  14. Tiangong TV S05E08: the crew is preparing for the incoming EVA mission. Still full of parcels!
  15. First one: The Deadline: Jia Yang (贾阳), the scientist of CAS said that Zhurong the Mars rover's transition from hibernation to autonomous awakening was from December of last year to December of this year. Which means the deadline for awakening is this December. Second one: Zhurong, is the first Mars rover from China. 185cm in height, and around 240kg in weight. The design life is 90 Martian days, equivalent to about 92 Earth days. Actual work was 347 working days. My understanding of this is "the doctor comes out of the operating room and says to the relatives 'Please prepare yourself'". The words on this: Earth-Moon System Direct Express
  16. Bought a supercharger that said can provide 65w, 45w, and 30w in each socket at "Relax Mode". When I just plug in, I just realize that it has nothing to do with Apple
  17. Brilliant as always. And he's almost the only "foreigner" who can pronounce "Zhuque" correctly I've seen
  18. One more player on the table. This is one of the most serious Chinese commercial rocket companies I've seen on cg graphics.
  19. Yep, the article also mentions that. The problem with both East and West is basically that the cost and technology of the stuff is more expensive compared to lathe cutting. I do think, though, that in the future, with advances in technology and increased manufacturing output, getting cheaper is a sure thing. "Laser manipulation of something inside another substance" reminds me of x-ray non-destructive testing. Of course, this have nothing to do with this topic.
