The problem of the orbit of launching satellite on Hainan Island has never been entirely arbitrary: if we launch to the south-east way, we also have to consider not having the wreckage of the rocket hit the Philippines. Personally I think Taiwan is the best place for us to luanch something. But, well, in macro terms "that day" is already counting down, so let's talk about it until "that day". After looking the orbit of Tianhe core module, it was launch to the north-east way of the island. This direction don't have any island anyway.

They will send the samples not only from the lunar and Mars may have in the future, but also from the asteroids. "The follow-up deep space exploration will be long-term and continuous. " Wu Weiren, cheif designer of China's lunar exploration project, revealed that "one of the main tasks of the follow-up is to detect asteroids in deep space, collect samples and take them back. In the future, we are also prepared to carry out exploration of other planets traversing the solar system. For example, consider the possibility of detecting Venus, detecting near-Earth asteroids that threaten the Earth, and achieving early warning, defence and disposal of them, and so on." He revealed that some of the missions have been included in the planning and demonstration. (transcript of the original interview in Chinese) "On the 100th anniversary of the founding of the New China (well, PRC, that's the some kind Chinese version political & historically correct way to call the name), I hope we can probe the edge of the solar system 100 astronmical units away." He said. Personaly I prefer the ship idea. But those three artificial islands in South China Sea I don't think they can't be used in this way: if they're not big enough, make it as big as they want. But anyway, the process now just "ha your ideas looks great, let's discuss it". Still don't reach "that's it let's do it" stage. My friend in Beijing said she was already saw it physically at the National Museum of China. Really jealous on it. And the YF-90 engine. All I can found is they completed 40 test with two other engines: YF79 & YF102's whole system test and YF-90 semi-system tests. The so called semi-system test probably like this before: fuel ingection but no ignition.

CZ-6A rocket successfully finished her maiden flight and launched two satellite:the Pujiang-2 (浦江二号) and Tiankun-2 (天鲲二号) . The CZ-6A is China's first rocket combined with solid fuel boosters (I feel quite surprised on that) and is for launching the SSO satellites. Pujiang-2 is mainly used for tasks such as conducting scientific experimental research and census of national land resources. And the Tiankun-2 is mainly used to carry out experimental verification of space environment exploration technology. https://www.nasaspaceflight.com/2022/03/cz-6a-debut/ And also CNSA published the scientific research facilities on the space station: Actually it have a video to introducing the "Combustion Scence Rack", "Independent Payload Racks", "Container-free Materials Processing Rack", part of the "High Microgravity Laboratory Rack", a test module simulate the space station and environmental simulation test system on Weibo, but you know, they don't think introducing them to the foreigner is important so it don't have subtitles. If you really want to watch it, here it is: https://weibo.com/6474280074/Ll4Pif2OM?refer_flag=1001030103_

When I was in one of the shore nearby, I see many kinds of seafood. And the boxes of Chilean cherries which absolutely impossible to grow out from the sea* Ah I see, Sea Cherries -

Damn I saw this below http://www.hisutton.com/Armored Stealth Boat.html I saw those smugling boat physically with a really fast speed before when I was fishing with my dad. And with the police's helicopter chasing them in the air. They don't smugle the car or drug anymore now. They smugle the freezing meat. -

Using submarine to smuggle drug is 'serious international criminal cases'. Using rocket to throw drug into somewhere, like US, is 'serious national security incidents'. "Others just want to make lots of money, but you seems really want to end our country!" -

Then I think it depends on your budget and also depends on what engine you can got. UDMH+NTO, the ‘Toxic rocket’, I don't know how the laws and rules about it in the west but it's hard to get it in Asia; Solid fuel may work and been used in many clips on the Mythsbusters, but it's hard to control. And actually they are high energy explosives; Liquid oxygen + paraffin, if you can got the engines such as RD-180, then the next problem I think is how you build the rocket. Careful Elon Musk Liquid oxygen + hydrogen, although the price to making those two things must be more stable than paraffin, more safer than the toxic rocket and more easier to control than the solid fuel. But the associated expenses are not cheap at all: refrigeration equipment, pressurised storage equipment, cryogenic transport equipment and, most importantly, engines. -

Looking back to the space from the disaster: Tianwen send back several new photos: the new 'selfie' from the Zhurong Rover which has a thin layer of dust compared to the previous one; The northern hemisphere of Mars is now in autumn, the season for dusty weather, but no significant dusty weather has yet been observed in the Zhurong roving area; And hi, Perseverance, we got you: ) After finish the second lecture in space, the Shenzhou-13 crew will prepared to start the preparation before returning to Earth. "Zhong Weiwei, a deputy researcher in the overall space medicine engineering room at the China Astronaut Training Center, said there was a lot of material to sort out before leaving, including the packages and various products on Tianzhou-3 that needed sorting out. The later Shenzhou-14 crew may be more than a month apart before docking Tianhe core module again, so these products and equipment need to be put in place in advance. Also important is the downbound piece, the samples brought back from the sky, to bring back important samples, these also need to be planned well in advance. From next week onwards, it's time to focus on this piece of work. " We don't know what sample that the crew will bring back to Earth actually but one thing is certain: they will bring those 40 1TB hard drives which loaded full of the 8K vedio clips (at least part of them). "If take 20 1TB hard drives back to Earth within 5 hours, this line will have bandwidth of 9320.6755555555 Mbps" The world's largest bandwidth network is a large truck full of hard drives driving down the highway from A to B.

The black box, found at 16:30 pm local time, has been sent to the investigation unit of the Civil Aviation Administration of China in Beijing. The exterior is badly damaged and the storage unit appears to be damaged. It has been identified as a CVR (Cockpit voice recorder). https://weibo.com/ttarticle/p/show?id=2309404750308193730889

Several new information: The pilot of the crashed aircraft was in good health and had a full flight history: All three pilots of the flight have valid flight licences and health certificates, are in good health and have complete flight experience, in line with the requirements of the Civil Aviation Administration of China. The captain was hired in January 2018 as a B737 type captain with a total flight experience time of 6,709 hours, the first co-pilot with a total flight experience time of 31,769 hours and the second co-pilot with a total flight experience time of 556 hours. "We are currently aware that all three pilots are also usually well behaved and have relatively harmonious family situations.", said by the Chiarman of the China Eastern Airlines Yunnan. The crashed aircraft met the maintenance release criteria and airworthiness requirements: The wrecked aircraft was introduced on 22 June 2015 and the maintenance of the aircraft has been carried out in strict accordance with the maintenance technical programme and the technical condition is stable and normal. Prior to take-off, the aircraft met the maintenance release criteria and airworthiness requirements and was released normally. The weather was airworthy on the flight path at the time of the crash: At the time of the crash, the weather on the flight path was airworthy and there was no dangerous weather. According to the records of the ground-to-air communication between the crew and the ATC unit, the aircraft had maintained normal communication with the ATC unit from the time of take-off from Kunming until the sudden drop in altitude on the flight path.

Several informational as far as we can got: What happened? China Eastern's MU5735 was take of at 13:16, March 21 from Kunming to Guangzhou. Entered Guangzhou ATC at 14:17 maintaining a cruising altitude of 8900m. At 14:20 the air traffic controller noticed a sharp drop in altitude and immediately called the crew several times but received no reply. Dispear on radar at 14:23 and comfirm it was crashed in Teng county in Wuzhou, the Guangxi province. Who's onboard? 123 passengers (no foreign visitors). 9 crew members (3 pilots, 5 flight attendants and 1 safety officer). How was the plane? It's a Boeing 737-800 which was introduced on June 22, 2015. 8,986 missions flown up to the time of the accident, with a total of 18,239 hours of flight time. How's the scene now? The orchard terraces in the crash zone were pounded into flats and puddles, thigh-thick bamboo ripped and fell, and some tree trunks were completely broken off. The core area of the rescue was about half the size of a football field, but the scattered area of aircraft wreckage was so large that wreckage was even found on the other side of the mountain. Specialist firefighters and rescue crews have been organised to search and survey the surrounding area within a 20km radius. No survivors have been found, but the local Red Cross has organised campaign to rescue medical supplies, including donations of plasma. And still can't found the black box yet. Until the black box is found and a conclusion is reached, I think we should refrain from speculating on who is responsible and from looking around for personal information about the crew and passengers: this is the respect due to them and their families. Describe only what we can see, make only the analysis we are sure of, make no unfounded inferences, don't jump to conclusions without investgation and wait for a more detailed accident report.

Rescuers have arrived on the scene and have sent back footage of the scene: they have found debris scattered throughout the depression, as well as the victim's wallet ID and other belongings. The handwriting on the piece of paper looked to be written by a little girl to me. They didn’t found the black box yet Video of the scene sent back by a Xinhua reporter.

Yesterday I read on the news that the wreckage of the wing was a considerable distance away from the centre of the crash, which means that it had disintegrated in the air. Then there's this: the crew should have nearly successfully changed their attitude before the crash, and in the end somehow it still failed. The last air disaster in Chinese civil aviation was the Yichun air disaster on 24 August 2010. Overall I choose to trust the pilots: they were a great bunch of pilots who managed to bring the whole plane back to the ground safely even when the windscreen burst and the co-pilot was sucked out of the window. If at last time they couldn’t dial any 7700 or call any mayday, there must be something really horrible was happened

Oh shxt… one 737 of China Eastern was crashed at Wuzhou in Guangxi Province. This plane got 123 passengers and 9 crew members. The FR24 app gives a last-minute descent rate of 31,000ft/min. Some people on the Chinese forum have tried to achieve this figure on the simulator, which shows the aircraft in a near-perpendicular attitude to the ground, in general agreement with the surveillance footage from the nearby mine that is currently coming out: plunging vertically from the air to the ground. The crew didn’t dial 7700 or call ‘mayday’

-The logic of a normal person: it is true that there is a high probability that peeing in the pool will not affect the health of others, but I still won't do it: after all, it's basic common sense for a human being and I'm in the water too. -The logic of TEPCO: you can't get sick in short time anyway, so I'll pee everytime in there if I swin in there. -
Why Nuclear War Is.... A MAD Scenario

...but they eat the raw fish. Actually, even befor the pandemic, many of them wore masks usually: because many Japnese are allergic to pollen. At 2017 I was been Japan for one month with my parents. My mum and dad have several Japaness colleagues who used to work together. What they suggest was: do a double check about the milk or rice or anything was produced by which part of Japan before we buy it, and try not to eat fish in Japan if you don't really have to, espeically the raw sea fish. One of them is my dad's best friend and that guy can speak mandarin without any accent. The "try not to eat fish" advice was from his mouth. -
