Old news, Already confirmed GF-11 is 10cm GSD from academician Li Deren. I am just waiting for the next gen optical sat with 2-4m mirror

So what resolution would be with 4m mirror ? 5cm ?

What if the aliens interpret the nude images as porn and annihilate all of humanity for the perceived insult? I think a much better idea would be sending a coded message of the Wolf Amendment.

So what resolution would be with 4m mirror ? 5cm ?

Based on Rayleigh formula (resolution=1.22*wavelength*distance/diameter) you get a GSD of :
4,1 cm in 247x693km elliptical orbit
7,8 cm in 470km circular orbit
6m in GEO orbit.
Operational resolution would be worse due to effects of the atmosphere.

Not sure if anyone's posted this, but the CZ-5DY and the new CZ-9 (22 looks like) apparently feature in the 2022 article about China's next gen rockets.

The details of their depictions is not that important, but the fact that they're depicting CZ-9 with the 22 or 21 variant as the future, is pointing in the right direction as it's the only variant of the CZ-9 depictions we've seen that is compatible with first stage reusability.

Unfortunately I can't locate the full article, if anyone else can find it that would be greatly appreciated.

海南交警提醒，自2022年5月9日8时起至5月10日8时止，文昌部分路段实行交通管制。

Hainan police announced a local traffic restriction in several roads near Wenchang Space Launching Center from 08:00, May 9 to 08:00 May 10, UTC+8.

So Tianzhou-4 cargo ship will very possibly be launched within 24 hours.
