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!"

One more: the first rocket to implement active controlled de-orbiting on its upper stage in China. "The upper stage of the rocket left orbit within 400 seconds of ignition and orbited the Earth approximately half a revolution before re-entering Earth in the safety area of Antarctica.", said by Space-Pioneer's official Wechat account. Have to say that this company brough a lot of surprise. Those technologies are actually quite close related with CNSA: such as the coal-based paraffin for this rocket was supplied by the 165 institute, the CASC's sixth academy. So, it's reasonable to assume that the tech about the upper stage wreckage de-orbiting fully under control of the future CZ rockets was tested first time in this launch.

Suddenly it occurred to me that their success had quite a "historical milestone" meaning: the first rocket fully using liquid propellent launch successfully in the first mission by private fund in the world. And it's also the first rocket using the liquid oxygen and paraffin launched from JSLC. via. https://weibo.com/1462552767/MArN5tgoY The official Wechat account of Space-Pioneer said that this launch made 7 first time in the world and in China: the first successful orbital flight of the world's first liquid launch vehicle for private spaceflight the world's first launch vehicle to apply coal-based space paraffin in flight China's first liquid launch vehicle that does not rely on a launch station China's first launch vehicle with a 3D printed high-pressure supplementary combustion engine China's first launch vehicle with 3-engine parallel engine technology China's first launch vehicle to adopt an all-aluminium alloy surface tension storage box attitude orbit control system China's first launch vehicle to achieve reuse of the rocket structure They also mention that they were extremely accurate to send the sats in orbit: Ø Half-length axis deviation 267m Ø Eccentricity deviation 0.000065 Ø Track inclination deviation 0.004° If we push the definitions further refined to use methane, there still have chance for other companies. Don't you think so, Landspace?

Galaxy Space (银河航天), the satellite manufacturers, in their official weibo said that, these four InSAR would be perform a wheal formation. The primary star will locate in the middle of the wheel and the three secondary stars are evenly distributed on the hub of the wheel. They form the first international formation of satellites on wheels. They also mention in their official wechat account said that, this system "has the capability of 1:50,000 scale mapping of global non-polar areas, which can quickly and efficiently carry out global land mapping with high precision. It has the capability of millimetre-level deformation monitoring, which can provide data support for the investigation and prevention of ground subsidence, subsidence, landslides and other disasters, and is a powerful tool for the early identification of major geological disaster hazards in complex areas. It has the capability of sub-metre high-definition wide-area imaging, which can provide all-weather and round-the-clock high-quality imaging observation of the ground, and the overall technology has reached the international leading level." More than that, PIESAT is planning to launch more in the future: now is the first stage - launch the first four satellites into 528km to validate the technology. The second stage they plan to launch 16 satellites including 4 C-SAR in co-orbit in 542km×49° LEO. And 4 group, 12 X-SAR sats in total at 522km SSO with 0.3~12m resolution. The final stage they plan to launch 18 including 8 C-SAR satellites like second stage. And 10 high resolution optical satellites which the resolution will be higher than 0.5m. After the completion of this satellite constellation system, it will have capability for global coverage in one day, revisit any place in one hour, and deformation monitoring every day for anywhere may need for Earth observation. Saw something interesting: the two crews in two different station performed mission in similar time, which the Shenzhou-14 crew and SpaceX Crew-4, had similar photo!

Xinhua: Shenzhou-15 crew complete their first spacewalk. CMS's official WeChat account said that this spacewalk lasted seven hours (in this link you can see several gifs about their spacewalk). For the first time, CCTV did not show the live broadcast of the spacewalk between 6pm and 8pm, even if it was taped.

Months ago, when I still study abroad and didn't back to China yet, I was bought a spy camera: the Minox C from one of the antique camera shops in London. I also bought a bit of film for it and the tools to cut from the standard 135 film to its special 8×11mm film. And I really try to use it to take some photo during my following museum trip. When I back to where I was living and looking at this little thing, and my iPhone mini, I suddenly realize what's the meaning about 'technological revolution'. Apart from taking photos or videos, and communication functions, its greatest power is its ability to bring information technology at an extremely low cost. But this "very low cost" is more a test of the user's industrial power and the ability to guarantee the supply of information in the place of use. The advantage of having information, not to mention war or not, just few months ago, a terrorist attack was carried out against Chinese people in a hotel where a number of them were staying in a country with an unstable security situation. And by setting up a WeChat group and communicating in real time about the movement of the terrorists, these Chinese people were able to wait safely for the arrival of the security forces and there were no casualties. At the other end of the spectrum, however, are some PLA exercises: the 'red side', which used to be 'invincible', is subjected to 'complex electromagnetic environment' by the exercise directorate - that is, they 'travel back' in time from the 2020s to the 1920s, which made them basically rely on messengers for communication. And, of course, there have been reports of high-tech exercises not far removed from the number of reports of such extreme manoeuvres. Details of the exercises are rarely made public, but the term "complex electromagnetic environment", which often appears in reports of PLA exercises, has basically become some kind meme among Chinese military enthusiasts: it describes the signal lag in phone calls, network lag in games, and lag in some webcasts. btw, the winning percentage of the 'blue side', with its high-tech, highly informative profession, is 32 wins and 1 loss in 33 battles.

The 300W-class LHT-40 Hall electric propulsion system, developed completely independently by the Lanzhou Institute of Space Technology and Physics, completed its first in-orbit test on board the S5 satellite of the Beidou Navigation Augmentation Constellation in micro-centrifugal space. The system works stably, and the performance indicators fully meet the user's requirements. (Via. Lanzhou Institute of Space Technology and Physics's official WeChat account)

Another cold launch on the sea: When he said he "found the platform" days ago, I was totally unimpressed. Until I just got the news on wechat that the rocket had launched. Add: launch video from CCTV's official weibo: https://weibo.com/2656274875/M9g4aeITX From Spacelens(云上天镜): https://weibo.com/7604660608/M9kAEqYUz (this one the closest one: they put the camera on the platform) and from People's Daily: https://weibo.com/2803301701/M9kI2tWLr Visually I think it's better to launch during the day. Although cold launch on the sea looks pretty 'violent' whatever during the day or night

Are you in China? If you are, you'll need a QQ or WeChat account. Chances are that you have one already. If you are not in China, why the hell do you want to download from that site?
