I've been always thinking about would there have (or had) some idiots try to make a 'poison rocket' "at home" and unfornately screw them up ... And now I got answer, well, part of... "Good luck and may you succeed" That reminds me a chemical joke in China: In China we got '84 Disinfectant' and the main components are NaClO. And the 'Toilet Cleaner' which main ingredients are HCL. Both are common, practical and both usually can be find in the bathroom. "Don't go inside you idiot! You just made a chemical weapon in the **** toilet!", shouted by a chemical teacher in my senior high school.

You know, in a weightless environment you can ride your bike in positions that no one else on earth can do:

When the teacher in one class in primary school was talking about dinosaurs being lizard-like things Me: Teacher, is there a possibility that these guys were furry like cats and dogs? Teacher: Are you going to say ammonites are actually quite delicious like last time? Me: nods*

There got four different types of Tianzhou: fully enclosed and pressurised, semi-enclosed semi-open bins, fully open bins types and open bins with non-pressurised cargo inlet and outlet walls. Just let the astronaut and robotic arm grab it if it launched Technically I think it should be fine: the tallest rocket launched here would be the CZ-2F/G, which is 58.34m. The CZ-7, which launched the Tianzhou, was 53.075 metres high, so the launch tower should be able to handle it. However, you need to consider the latitude: 40 degrees north versus 19 degrees north, which is about the difference between Virginia and Mexico City Haiti, and the extent to which this saves rocket fuel is not negligible. I was chasing the ship for several days. The route it ran basically is close to the shore no more than 10 to 15 nautical miles. It's not going to middle of somewhere pacific so it is safe. CZ-7 is a rocket that got 3.35m diameter. The height of the AN-225 cargo hold was 4.4m and Y-20 is 3.5m . Considering that there is another container in the outer layer, it must be quite hard to shove it into the cargo hold even the An-225. And not to mention the cost of air transport: needless to say, one sortie is certainly not enough.

CZ-7 Y5 rocket which will launch the Tianzhou-4 cargo ship has arrived and leave the Qinglan port, heading to the Wenchang Launch site https://weibo.com/6142289604/LnNgmzvz2

And a idea about "inflatable waste stowage cabin" (this source got pay wall) When it folding: Deployment process of the inflatable garbage cabin: "The developed 2.5 m diameter, 3 m long, 120 kg (including 2 sets of hatches 79.6 kg) prototype rubbish module can be folded into a rectangular body with a side length of 1.5 m and a height of 0.1 m. The ratio of folded to unfolded volume is about 1:40. The results show that the inflatable rubbish module is light in mass, can be folded flexibly, has high folding efficiency, has a stable and orderly unfolding process, can be used for smaller volume launch of the folded inflatable module It can also be unfolded in orbit to become a large space station trash module." I've just imagined it painted white and it's not only a bit familiar to a KSP mod, it's even a bit cute

Someone got a interesting idea: make hatches like the Common Hatch in the ISS but doesn't open in the same way: ”A large diameter rectangular sealed hatch device for manned spacecraft“ And weeks before I saw a image but I couldn't found the original source: Make a highly rigid and high load-bearing tursses and dock at the second core module may launch in the future. Attach the exposure test platform, on-orbit fuel replenishment system, on-orbit maintenance of satellites, a smart little trolley and berths for additional solar panels. In terms of aesthetics, I don't really like the idea.

It shouldn't take long if everything goes well. Becuase a satellite image from February 19 shows an additional 70m shadow at Landspace's launch site, estimated to be about 50m long based on solar altitude angle, which means that the rocket launch test for Zhuque-2 was probably carried out: https://weibo.com/2645044133/LgkDVxoCD?refer_flag=1001030103_ If I really had to guess I'd say probably around mid to late this year. Personally I prefer the Landspace

To be honest, no new experiments have been carried out and the following is the most recent progress they have made that I could find. State-run commercial launchers: Company name Rocket Rocket type Engine type ExPace(科工火箭) KZ-1, KZ-1A Small solid launch vehicles Solid CHINAROCKET(中国火箭) Jielong-1 Small solid launch vehicles Solid Both two company don't have any launch till now. The EXPACE test a Liquid oxygen/methane engine "Ming Feng"(I think can translate to Crying Phoenix) for 200 seconds but I can't see how much thrust does it have. Tier 1 commercial companies: Company name Rocket Rocket type Engine LANDSPACE (蓝箭航天) ZQ-1, ZQ-2 Small solid launch vehicles Medium liquid oxy-methane launch vehicle Solids, liquid oxy-methane i-Space (星际荣耀) Hyperbola-1 Small solid launch vehicles Small liquid launch vehicle Solids, liquid oxy-methane Onespace (零壹空间) OS-X, OS-M Small and medium solid launch vehicles Solids LANDSPACE's business valuation of over 8 billion RMB at the end of 2020. And they built them "space center" at Jiaxing in last year. "... with the first phase covering an area of 40 mu (≈2667m2). The project consists of a medium to large liquid rocket assembly and testing plant, a space technology simulation and testing centre and supporting facilities, and a gathering of upstream and downstream supporting industry chain enterprises.Within three years, the project will form a cluster of launch vehicle assembly and testing facilities, including a launch vehicle assembly and testing plant, a semi-physical simulation laboratory, a comprehensive ground test laboratory, a rocket storage tank production line, a simulation design centre, a data management centre, etc., which will strongly guarantee the mass production capability of the basic and extended launch vehicles of the Zhuque II." The last news is they completed the assembly of the first-stage enignes for the ZQ-2 rocket. You can find out more in there: http://www.landspace.com/news/news_108_1_gb.html iSpace's: since the last successful test of their reusable engine at 2020, there have been no further developments news on their engines. Last August the luanch of the SQX-1 Y5 was fail and they finished the "quality problem close loop" at last November: means checking everything that should be in the rocket and related to the rocket from the beginning. The reason they fail last time was "The silicone rubber at the cover of the fairing's release bolt box is sticking to the wind shield, resulting in the fairing not separating." Onespace: they make the delivery of two types of Hongming series solid fuel engines. And a certain types special power engine was completed it's test (The italics imply that there is a strange mechanism of secrecy here). I think it will be a special solid fuel engine maybe. Tier 2 commercial companies: Company name Rocket Rocket type Engine Galactic Energy (星河动力) CERES-1, PALLAS-1 Small solid launch vehicles Medium liquid launch vehicle Solids, liquid oxy-paraffin Deep Blue Aerospace (深蓝航天) Xingyun-1. Xingyun-2 Small liquid launch vehicles Midium liquid launch vehicle liquid oxy-paraffin Spacetrek (星途探索) Expore-1 Starway-1 Small solid launch vehicles Solids Galactic Energy has secured RMB 1.27 billion in funding, which they say will be used primarily for the development of a reusable medium-to-large commercial launch vehicle. What they plan for is finish the maiden flight at 2023. They complete the test of 40t thrust reuseble engine at 2019. Deep Blue Aerospace completed nearly RMB 200 million Series A funding round. The last progress was the 100m Vertical take-off and landing flight test of the rocket: Spacetrek's progress sounds a little bit "violence": they successfully launch the first supersonic cruising target D140-Y1.

CZ-4C rocket successfully launch the GF-3 03 satellite. GF-03 is a C-SAR satellite with 1 metre resolution and 1 day revisit ability. After launch into orbit, it will operate in a network with GF-3 & GF-3 02 satellites and forming a constellation of land and sea rader satellites. And the mission badge for this mission: Read an article named "A design of dust analyzer for future Main Belt Comet exploration mission" (https://doi.org/10.1016/j.asr.2022.02.035) "... MBCDA (Main Belt Comet Dust Analyzer) will measure the following physical quantities: cumulative dust mass flux from different directions, momentum, velocity and mass of single particles coming from the nucleus, dust velocity and mass distributions vs. time. Moreover, some hints about dust components can be inferred."

And Xuyang 16 cargo ship which departed from Qinglan Port next to the Wenchang launch site to Tianjin at the end of last month, has departed from Tianjin and is returning Qinglan Port. I think we will see news about the arrival of Tianzhou-4 at the Wenchang launch site in 2-3 days' later.

I found a new picture of the construction of the Xuntian telescope The orginal source: https://www.cas.cn/cm/202204/t20220402_4830439.shtml

Sunny, with chance of CZ-3B

I was watched a not too worth to share video talking about the space station in the deep sea. ThenI do more searching and I found something I missed: The simulate Mentian Module underwater for training: And we can comfirmed the plan about shifting the solar pannels which now at the Tianhe core module to the both truss structure at end of Mengtian and Wentian module does exist: The original source from the Huang Weifen's Weibo, who is the chief designer of astronaut system of China Manned Space Project.

Damn I've trying to do some April fool!

And CZ-2F/G actually did launch something Buran-like thing

[snip] Tips: CZ-2F

Someone got something interesting shots

The full vedio of second lecuture in space station with English translate I like the way how Wang Yaping passing things to Ye Guangfu

Somebody use Minecraft to simulated the Tianzhou-2 mission. The correct way to play Minecraft is watch the others how to play https://www.bilibili.com/video/BV1rY411J7oc?spm_id_from=333.337.search-card.all.click

Tianzhou-2 re-enter atmosphere over the South Pacific. It has been on mission for 10 months and one day. Thank you Tianzhou-2! The mission badge on the enginer's shoulders who was on the site: The mission badge design by the 8th institude and can buy it online:

Actually many of them was published with English but if people not speacking Chinese you really don't know how to find them. That's really annoying me somehow: do you know how cool you did, CNSA? And well... you know, just like what I share about the science rack will be use on the space station in future, that things really don't have any English translated introduction (yet) except the two of them was already mounted on the core module.

[snip] Well actually the commercial space company in some way is "we got some big bosses who earn lots of *** money, so let's (CNSA) take the lead and let them throw them *** money into the sea". The other one like the Changguang Satellite which focusing on the high resolution satellite and Tianyi Space which focusing the SAR satellite and so on, also have the technolegy and ecnomic founding by the government and CNSA. I think just like the Space X: Falcon 9 couldn't come out from nowhere right? Some technology if only depends on CNSA to develop it, it will have fanancial problem. Leading and involving private capital is a good and somewhat "catfish effect" thing to do so. If you understand what CNSA did as a somehow 'video game', those comercial company is 'DLCs'. As for why 1/10. I think somehow their thought is they don't think what they did is "we don't know its cool enough to show it": there are already have the block of the Chinese possitive information on the net anyway. Let those guys insist them though as long as they can.
