Unboxing, unboxing and unboxing: Shenzhou-15 crew are unlocking the Combustion Science Rack in Mengtian Module. Via. Tiangong TV S04E02 from CMS's official weibo I cut out and rotated the screenshot of parcels in the top left corner: From left to the right are: Resistance exercise device accessory kit 2 (the green one), Extra-vehicular 5G transceiver a and b (both black parcels)

Did ISS have any bath broom

I think there's another set of Soyuz in the assembling plant now, isn't it?

A cold launch but didn't use TEL vehicle this time I watched an introductory video about Chinese TEL vehicle (but of course it's full Chinese without English subtitles). That make lots of sense why CNSA using same trucks as PLARF: This is because the manufacturers of TEL for launch vehicles are from the "Wanshan Plant(万山厂)" and "Tai'an Plant(泰安厂)". The full name of "Wanshan Plant" is Hubei Sanjiang Aerospace Wanshan Special Vehicle Co. It's a manufacturer under the China Aerospace Sanjiang Company, aka Forth Institute of CASIC. The "Tai'an Plant" full name is Taian Aerospace Special Vehicle Co. LTD (I don't know why they put a wrong picture of a proton rocket on their website, maybe it was the work from some interns). Which is a manufacturer under China Academy of Launch Vehicles, aka First Institute of CASC. In 1998, Wanshan began to master the development of special vehicle technology: through a joint venture with the Minsk Automobile Plant in the form of a technical participation in the form of a transfer of technology, and the restructured Wanshan Company, Sanjiang Volat Special Vehicle Co. Ltd. was established. With this, Wanshan thoroughly digested and absorbed the technology of the MAZ-543. Based on that, a series of military heavy-duty off-road special vehicles were launched. Such as the WS-2500 10×8 chassis, which is used in the DF-16 and DF-21 missiles, the WS-2600 10×10 chassis, which is used in YJ-12B missiles. After 12 years of good cooperation between both sides, the Minsk side handed over the technology for the six-axle drive to Wanshan in 2010. This resulted in WS-2900 12×12 chassis and laid the technical basis for the development of the subsequent 8-axle chassis. But Wanshan didn't deliver a satisfactory result on the 16×16 chassis because of the transmission structure and lack of power output of the engine. However, HTF5980A 16×16 chassis developed by Tai'an, finally succeeded in technology and production after eight years of research and development. The remarkable thing is that the central government decision makers in the planning of the overall strategic layout of the development of the country's special vehicles and didn't let Tai'an also go "Sino-foreign joint venture, the introduction of technology" development program. Instead, it was asked to follow the path of independent research and development with the technical support of other sister units. Unlike Wanshan's technology which is introduced through foreign cooperation, Tai'an's core technology has accumulated completed independent intellectual property rights. Before 2010, their only presentable products were TA5380 which for the HQ-9 anti-air missile and TA5450 for DF-15 tactical missiles. In 2002 Tai'an started the development of eight-axle special vehicle and in 2006 the first generation HTF5980 was designed. The performance of the first generation at this time was still lacking, so after four years of technical work, they completed the design of the 16×16 heavy-duty off-road special vehicle HTF5980A and HTF5980B. The technical difficulties of the 8-axle drive technology have been completely overcome. Naturally, in the subsequent competition, Tai'an's HTF5980 beat out Wanshan's WS series chassis and was selected as the chassis for the Chinese ICBM TEL vehicle, such as DF-31A and DF-41. There are rumours on the internet that Tai'an is working on a diesel-electric hybrid engine. But this kind of thing is basically in a highly secretive state where it cannot be proven or disproven. So, I won't make any speculations. So now, as for why Kuaizhou or something using TEL, well, "is it strange for a subordinate to produce something useful for its superiors?"

A meteorite fell in Pujiang Conty, Jinhua City, Zhejiang Province. CCTV footage of the meteorite as it crossed the sky The meteorite itself has been found, but the local dialect spoken by the video shooter is "an unspeakable alien language" even for me, so I won't put the source. Add: translator in the comment who understands the local dialect said that the video shooter was saying that this was part of the meteorite she had found and that the stone weight about '3 Jin 4 Liang' (which translates to around 1700g) one more video, she was making a video and...

That's exactly what I think hahaha

Landspace official weibo: 14th Dec, 16:30 CST, we are at JSLC on the first flight test mission of the new private commercial launch vehicle, the Zhuque-2. The engines of first and second stage were running normally but the vernier engines of second stage didn't. This led to the failure of the launch mission. The exact cause is being further analysed and investigated. At least this photo is surprisingly good I give it that.

Alright, CZ-2D Y80 rocket. CZ-2D rocket was successfully finished 15 missions this year, which made a new record for the number of launches of this type of rocket. Via. https://weibo.com/5616492130/MjCMol8rw According the patches of previous three Yaogan-36, I believe there's at least 2 more to go next two months. Maybe can forms a hexagon finally

PLASSF: 15th Dec, 2:25 CST, the Yaogan-36 was successfully sent into planned orbit by CZ-2D rocket at XSLC. (The number of satellites in the constellation and the number of rockets will have to wait for dawn in few hours later for further information)

"Failure is the mother of success", as a Chinese proverb says. At least there were no "fireworks" at the launch site. Good luck with the second launch and hope the investors not getting too mad on this hahaha

kaputttt (ish

Someone post a 4 second video about Shenzhou-9 landing and was flips over: https://weibo.com/7394207363/Mj4RzDm6c (OUCH!) In this comparison, Shenzhou-14 didn't cut off the parachute doesn't seem to be something big deal. Fun fact: the first female taikonaut, Liu Yang, was in both Shenzhou-9 and 14 missions

My understanding of the messages given by the Chinese domestic universities and the relevant experts is that "the 'dish' of cooperation from our Russian friends is indeed delicious, but we will not totally rely on it. We will try ourselves as we can". While it is true that there have been unpleasant incidents, large or small, in Sino-Russian and even Sino-Soviet cooperation, I don't think that the relevant Chinese authorities have developed what they perceive to be almost as anti-Russian a tendency as their European counterparts, as the article suggests (OK I hear the avoid politic alarm sorry). I wouldn't presume that "you didn't mention someone in one of your conversations" and assume that "you must have a bad experience with that guy these day" Same thing on the CR929 civil aircraft project: there are always voices saying that China will leave Russia behind to work on this project itself. "It's time for get fully prepared to develop and make our wide-body civil aircraft independently!", shouted by an elder AVIC engineer in his article (careful it's fully Chinese). In general, China has 'eaten up' nearly all the technology from the Soviet and Russia over the last 2 to 3 decades, and the tendency I can see is learning from the forefront of European and American experience and technology, while incorporating China's own experience of use and manufacture to develop China's own technology. And this, with no offence, is really something that our Russian friends are finding it difficult to provide these days. But one thing is for sure: collaboration always is the best, whatever what you think about that and which side you pick. And collaboration is by no means superior or inferior, whether with Russia, Europe, Middle East, or other countries that are currently underdeveloped for the time being. At least that's what I believe.

12th Dec., 16:22 CST, the Shiyan-20 A/B satellites were successfully launched at JSLC by CZ-4C Y57 rocket. CASC said that this launch also is the last launch this year in JSLC. add: the mission patch this time: Anyway, it's always good to working together. And Chinese halal food are quite tasty by the way: it's a bit like beer for me, I can skip it, but always want to do it once after a long time. So, if in the future there's really have someone from middle east can go to the station, I don't think there's any food problem

Looks like the exposure experimental platforms of Mengtian Module has fully deployed. We can see both airlocks for astronauts and experimental payloads because they are in the I Quadrant of both Wentian and Mengtian Modules that always remain towards to the Earth. Quite curious did Tianzhou-5 has brought some experimental payloads that need to mount outside or not. p.s.: CSS didn't use 'starboard side' and 'port side' to define the left or right. And different with ISS, CSS distinguishes between 'floor' and 'ceiling' in the cabin. I Quadrant: the floor, which always towards to the Earth II Quadrant: port side III Quadrant: towards the 'sky', which in space is the opposite direction to the earth IV Quadrant: starboard side

I think it's more relevant to science than CNSA thread, so I put this there. That cockpit just... I would like to call it piece of art

oops, missed one The mission patch this time My friend shared me a Landspace's official online store. They're selling something like mission patches, shopping bags and phone cases etc. Unfortunately, their cases don't seem to be adapted to the size of the iPhone mini which means I can't give them some little support

Another rocket launched on sea: Seems like the China Rocket Company are quite confident on their technic: taken 14 satellites on its maiden flight. Hope everything goes well!

71, WOW! The scientist who banded her probably not even alive now

CASIC didn't paint the truck green this time. Although I really thought that if paint it white or something will looks more 'peacefully' before, but... I don't think so now.

After 880 days, Kuaizhou-11 is back! Close-up video on the attitude control engines at the head of the rocket: https://weibo.com/7604660608/MiwEGc3x

A video about Shenzhou-15 from arrival to the assembly plant to launch to the station: https://www.bilibili.com/video/BV1484y1k7ro/?spm_id_from=333.337.search-card.all.click&vd_source=6fef304b8d0c4737896e6b702ddfbfb3 The three modules of Shenzhou were transported by Y-20. Seems like the number of Y-20 in PLAAF are already quite sufficient. And another video about the CERES-1 Y4 'YOUNG FOR YOU' from manufacture to launch into orbit https://www.bilibili.com/video/BV1NW4y1g7Fy/?spm_id_from=333.851.b_7265636f6d6d656e64.1&vd_source=6fef304b8d0c4737896e6b702ddfbfb3

Just like my first time playing Kerbal. But however, the North Korean has put a (or some I can't remember) camera on the missile. Pretty weird they never pick the end of the missile dropped back to see the relevant data.
