It should be added that the administrative area is 7,268 km2 - roughly seven Hong Kongs. The peaceful version is that the place is famous for its pears and tomatoes: they are surprisingly sweet because of the difference in temperature between day and night. Is also a very good place to take a driving tour. Not that peaceful one... well just look at those PLA watchers... Quote Link to comment Share on other sites More sharing options...

steve9728 Posted June 8, 2023 Share Posted June 8, 2023 (edited) It broke the domestic record of "multiple satellites launched by one rocket": the last one was 22 sats launched by CZ-8 Y2 rocket last April 30. These two days are the days of the "Gaokao", which are the exams for high school graduates to enter university. The physics exam has this new question: The mass of the Chang'e 5 lander is m, the acceleration of gravity at the lunar surface is 1/6g, and the angle between the four legs of the lander and the vertical direction θ, the pressure of one leg on the lunar surface is: A: mg/4 B: mg/24 C: mg/4cosθ D: mg/6cosθ Edited June 8, 2023 by steve9728 Quote Link to comment Share on other sites More sharing options...

steve9728 Posted June 12, 2023 Share Posted June 12, 2023 (edited) A pair of 75L Xenon tanks were installed at the outside of the Tianhe core module. They were taken out from the cargo airlock at the MT module and were transferred and installed by the robotic arm. "被动端(passive side)" were the places where the tanks were installed. Previously fuel for the two pairs of hall engines' ignition was from two 12L tanks inside the TH module.

steve9728 Posted June 12, 2023 Share Posted June 12, 2023 (edited) People in Beijing captured the second-stage wreckage of CZ-2F Y16 re-entry: https://weibo.com/1423392492/N51SAyMHK CMS: According to the monitor and analysis, at around 01:34 on 13 June 2023 CST, the wreckage of the second stage of the CZ-2F Y16 rocket re-entry the atmosphere. The landing area is located at 130.6°E, 38.3°N in the surrounding sea. Most of the components were ablated and destroyed during the re-entry process.

steve9728 Posted June 14, 2023 Share Posted June 14, 2023 On 6/6/2023 at 9:57 PM, steve9728 said: Currently, the station: "The project is constructed by China Construction First Group Corporation Limited and is located within the Hainan Commercial Space Launch Sites in Dongjiao Town, Wenchang City. The project building is a reinforced concrete frame structure, reinforced concrete shear wall structure, steel pipe tower structure, grade 2 fire resistance, and can withstand earthquakes of Liedu 7. The construction includes a power centre, rooms for test work, wastewater treatment facilities & equipment, and small solid rocket launch stations, etc. The planned construction period is 180 days." Emmmm... not the news I expected. But it's a good one for those companies in the coastal provinces. Seems that both France and China have been working together quite happily recently.

Check out the CSS shots! A new record: 41 satellites launched by CZ-2D Y88 rocket at TSLC at 13:30 CST today - it just broke the multiple satellites at once in China - previously was 26 by launch by Lijian-1 days ago. These 41 satellites were from the Jilin Changguang Company Source The next record that I expected previously was 30+, but, damn! An official CNSA account, "Space Supply Chain Service Platform", has posted a "Satellite Launch Opportunity Auction Platform", where bids for CZ-6C rocket launches start at 80,000 RMB/kg.

steve9728 Posted June 15, 2023 Share Posted June 15, 2023 (edited) List of these 41 satellites: Jilin-1 Gaofen 06-A 01-30 (30 sats, 20kg each, side hanging. Has five spectral bands: panchromatic/blue/green/red/near-infrared. With a maximum panchromatic/multispectral resolution of 0.75m/3m and a width of around 18.9km) Jilin-1 Gaofen 03-D 19-26 (8 sats, 43kg each, side hanging. Also has five spectral bands. Resolution of 0.75m/3m, and a width of around 17km) Jilin-1 satellite platform 02A 1-2 (2 sats, around 40kg each, mounted at the bottom. Detailed technical specifications are unknown, but it should also be a sub-meter class optical satellite) Jilin-1 ** model (only one, 40 kg, mounted at the bottom. Detailed also unknown) Now, the number of Jilin-1 satellites in orbit is 108 already - this marks the success of the Jilin-1 satellite constellation project in achieving the goal and milestone of "100 satellites in orbit this year". Currently, it can be 35 to 37 revisits per day to any location worldwide. By the end of this year, it is expected to reach 140 satellites, completing the goal of the first phase of the constellation's construction. By then, it will be able to revisit any location worldwide within 10 minutes. Edited June 15, 2023 by steve9728 Quote Link to comment Share on other sites More sharing options...
steve9728 Posted June 15, 2023 Share Posted June 15, 2023 (edited) A new payload - "exposure experiment device for space radiobiology", has been taken out from the cargo airlock at the MT module and mounted outside of the station: Tiangong TV S05E02 "This device will provide services for experiments on radiation damage, genetic mutation, preparation of radiation protection drugs, and biological assessment of radiation risks. It's expected to work for approximately five years." Add: the location that the robotic arm put in the video was the "transit position", which is on the 'leeward' side of the MT module, the side near the solar arrays of the core module. Then the arm has been adjusted and mounted on the 'skyward' platform: Edited June 15, 2023 by steve9728 Quote Link to comment Share on other sites More sharing options...

steve9728 Posted June 15, 2023 Share Posted June 15, 2023 CNSA has now agreed to requests from NASA and other national aerospace agencies to use the Queqiao lunar signal relay satellite service, to help them with future lunar exploration missions. It's always best to cooperate for sure. But actually this service is some kind of "automatic law-breaking machine" for someone. Quote Link to comment Share on other sites More sharing options...

steve9728 Posted June 21, 2023 Share Posted June 21, 2023 CNSA's official WeChat account: Why is it so hard to get a round-trip ticket to Mars? (Chinese link warning) ... "There are many more challenges to a manned mission to Mars, so we will only give a general overview here. One final note: we are landing people on Mars (or other 'habitable' planets) to study the potential for past and future long-term support of life on Mars. It is not necessary to migrate to Mars or conditions on Earth are so bad that we have to go. Even the Sahara and Antarctica are paradises compared to Mars." "While life as a whole phenomenon is very hardy, species-specific, it is fragile. Throughout the evolutionary history of life on Earth, there have been numerous mass extinctions: higher oxygen levels, extinction; lower, extinction; higher temperatures, extinction; lower, extinction. The parameters for survival on Mars require a great deal of effort to adjust to "just survivable", or more likely, not at all. So, for the time being, humans are still studying and researching Mars, and on the subject of transforming the world, let's take care of our home planet first!"

steve9728 Posted June 23, 2023 Share Posted June 23, 2023 CASC's Fourth Academy completed several parachute deployment tests for Tianwen-2, the asteroid exploration and sample return mission: https://mp.weixin.qq.com/s/mxkk9D4kU2-QnwoATp88cg "The high-altitude deployment tests went through two phases and lasted for two years and six months. During this time, the team overcame several difficulties such as epidemics and extreme heat and cold. And completed many key technical challenges. They adhere to the concept of 'success doesn't mean maturity, maturity doesn't mean reliability'. The test team treated each test as the first flight and first test to ensure that nothing was wrong." Logically, it should be technically possible to continue with the tech of the Chang'e 5 parachute. But more experimentation is never something bad.
