Is she being treated in the media as 'just an astronaut' or some kind of special case 'look what Women can do' thing? It give me feels like: 1. she's a astronaut who used to be a excellent pilot in PLAAF; 2. she's a mother who have a cute little girl; 3. that's what she did in the space: blablabla Overall as my understand I prefer "She's an astronaut who just happens to be a woman".

steve9728 Posted March 12, 2022 Share Posted March 12, 2022 (edited) Speaking of female astronauts, it occurred to me to consider the existing CNSA crewing pattern for manned missions: astronauts with multiple or medium to long term mission experience as Commander A + Astronaut B with at least one mission experience + new Astronaut C with no experience. So while the possibility of female astronauts B and C in the future cannot be ruled out, there is also a high probability that there will be a female commander A: the fist female astronaut Liu Yang have 13 days experience and the second female astronaut, Wang Yaping, who is now in space and will have accumulated more than half year of mission experience when she returns to Earth next month. PS: I really do hope the Deng Qingming, which a really 'unlucky' one as backup crew for 3 missions can be selected in Shenzhou-14 or 15 mission and launched to the space station Edited March 12, 2022 by steve9728 Quote Link to comment Share on other sites More sharing options...
steve9728 Posted March 13, 2022 Share Posted March 13, 2022 (edited) The YF-77 hydrogen-oxygen engine, which has been optimised for reliability, finished the 520 second long-range test run. This type of engine is used for the core first stage of the CZ-5B rocket to be lauched with the "Wentian" module of the space station. We can start waiting for the news about the arrival of the "Wentian" module and the CZ-5B Y3 rocket from the northern Chinese city of Tianjin to the Wenchang Space Launch Site.

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.

Why didn't they glide, I wonder? https://daisetsuzan.blogspot.com/2019/06/gone-in-35-seconds-spatial.html Quote Spatial orientation refers to the natural human ability to maintain our body orientation and posture in relation to our physical environment, at rest and during motion. From an evolutionary point of view humans are adapted to maintaining spatial orientation to the ground. Three-dimensional environments encountered during flight or deep diving are unfamiliar to the human body and can create sensory conflicts and illusions that makes spatial orientation difficult or sometimes impossible to achieve. This is my guess as to what happened. Edited March 22, 2022 by SunlitZelkova Elaborated Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...

Obviously wings don't just fall off, unless it was maintained really, really poorly. I still like SunlitZelkova's explanation, though. The same exact thing happened with a JASDF fighter over the Pacific. No mayday, no ejection, and it wasn't the aircraft's fault. The pilot became disoriented, and his sensory inputs gave him false information. It happened despite having instruments in the cockpit which he could have used.

steve9728 Posted March 22, 2022 Share Posted March 22, 2022 (edited) 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.

Pretending it's factual is wrong, but making educated guesses based on past events is fine and perfectly normal. So, what I want to know is this: If the airliner really did shed parts mid-air, what could have caused it? Could frantic maneuvers caused by disorientation have done it? I know very little about airliners, except that they have huge safety margins. Perhaps @mikegarrison could help? Quote Link to comment Share on other sites More sharing options...
mikegarrison Posted March 23, 2022 Share Posted March 23, 2022 I will not be discussing anything without more information. The crash site is known. If the data recorders survived, there should be some information released sooner or later. The protocol is clear that the country in which the accident occurred is in charge of the investigation, but they usually involve the regulators from the country that was the "state of design", which in this case would be the NTSB.

steve9728 Posted March 23, 2022 Share Posted March 23, 2022 We can see the plane suddenly fall off altitude and the pilot try to pull up, even at the very last moment. I saw some media point out this: FAA found the cracks on the "Pickle Forks" which discovered on aircraft being overhauled in China during conversion from passenger to cargo aircraft.

steve9728 Posted March 23, 2022 Share Posted March 23, 2022 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.

"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.

steve9728 Posted March 30, 2022 Share Posted March 30, 2022 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.
