Record number of Chinese people in space.

SZ-14 welcomes SZ-15 -

Love how they've decorated the station with some home-grown house plants -

According to China Military Power Report 2022, China has 260 ISR satellites, about 50% of the ISR systems in the world. China has been launching 20-30 ISR satellites a year since 2018. Those who claim that China can't find targets are just "whistling past the graveyard."

Didn't notice your post until now.

I must say that this is a surprise. Long Lehao is playing us.

From his wording, engines of all 3 stages have conducted full system test. However we don't know exactly which engines are they. This is what I gathered from open reports. Green means full system hot test, Blue means half system (turbine, GG combined) test. A full YF90 was assembled in 2021 but never heard it conducting full test.

CZ-9	2011​	2021​	20220917​	2022​
1st stage	YF130	YF135	240t LOX/Kerosene	200t Methene
2nd stage	YF90	120t LOX/LH	120t LOX/LH	120t LOX/LH
3rd stage	YF79	120t LOX/LH	120t LOX/LH	120t LOX/LH

Two possibilities

1. Long Lehao was talking about 2011 version of CZ-9 if CASC did not withheld information from the public regarding engine tests.
2. There are more engines completed full test than CASC has shared with the public.

Imo, it's also possible that he is counting YF-130 as the "same" as the 240t kerolox engine, where the 240t kerolox is a single chamber YF-130 variant and thus is already technically "tested" (though of course would still require its own independent single chamber test in future).

China has officially named its Wide Field Survey Telescope (WFST) after the ancient Chinese scientist & philosopher Micius or Mozi, who is credited as the first to conduct optical experiments. The optical telescope, measuring 2.5m in diameter, is expected to be completed by 2023..
