Footage from the latest recent full-system test run of the 85-ton Qiaolong-1 engine, which lasted 50 seconds.


These are the first set of close-up images of the actual Qiaolong-1 engine I have come across. Previous ones were all scale display models or were on test stands.

Chinadaily confirms that the CZ-10A "low altitude flight" planned before the orbital launch (and likely before the end of the year) will include a recovery test.

CCTV also confirmed it will be recovered offshore.

And it was announced that the CZ-10 static fire test article will be repurposed for test flights (either the low altitude test or the Mengzhou in flight abort) :

I've seen a couple informed blogger/insider allude to meaningful progress of the CZ-12A/4-m-RLV (Methalox) in the past months, if ZQ-3 ends being delayed more because of this failure CZ-12A may have its inaugural launch & landing attempt before.
SAST's CZ-12A Upper stage was undergoing tests on the Space Epoch test bench/launch pad in Haiyang

8th batch of Guowang Constellation has launched.

this is the 4th batch of satellites being launched in 18 days..
9th batch of Guowang Constellation has launched.

this is the 5th batch of satellites being launched in 21 days..

A Long March 6A lifted off from Taiyuan, sending the 9th group of Guowang broadband satellites into orbit.

In just the last 10 days, we saw a significant plane change maneuvers from the (presumably) docked SJ-21/25 satellite pair. Plane changes are VERY expensive in terms of fuel requirements, and it is very rare to see objects in GEO do anything other than minor station keeping adjustments to their inclination and RAAN, usually a fraction of a degree. Well, China is changing the game…they changed SJ-21/25’s inclination more than 6 degrees and by our calculations used about 332 m/sec of fuel to do so (this is a HUGE amount for a GEO object).

on the guowang constellation, looks like wiki page here keeps track of number of satellites per launch

Please, Log in or Register to view URLs content!

since they are launching more frequently now, good to remember how many they are actually launching.

Looks like each LM6A can launch 5 sats, LM8A/12 launch 9 sats. LM-5B launch 10 sats.

IDK what the rocket production rate is, but they are keeping it up. They are essentially at 50 per month at current launch rate. Which is sufficient until they get larger rockets.

IIRC, GW sats are heavier, so you can't launch as many of them per launch
