CZ-5DY does have plan for LEO mission, possibly the new generation crew spacecraft. It would be the single stick variant.
See the one on the left.

Beside LEO crew mission, there is nothing to stop it being used for satellite mission except possibly the price tag.

CZ-9 is also intended for near earth mission. That is actually one of many reasons for its seemingly lower lunar payload/mass ratio because the design can not be optimized for a pure lunar mission like Saturn V.

I can not answer the question of version 11 and 21 with certainty. I guess that they are being developed (key tech and design phase) at the same time right now. 11 has an early start. 21 is a new idea recently after CZ-5DY became more realistic negating the modular idea of version 11 (killing the A and B variants). YF-135 and YF-130 are more in parallel from the beginning than CZ-9. The rumor of 360t engine has been for some time. I also guess that if 21 progress fast enough, 11 may not see fruition. It is like the EM catapult vs. steam catapult. CNSA will take the one on time and better.

With Version 21 of CZ-9 being a monoblock design, it is possible the dual-chambered YF-130 will still be used in boosters for a future growth version of CZ-9 like a single-staged CZ-9 dedicated to LEO missions much like the CZ-5B today.

Hi!

For the last years I have been getting information about the launch of small Chinese sats but with time passing I don't see those launched, or I simply cannot find information about this small sats anymore. Maybe some of you can help with this?

- Dagong Weixing (a CubeSat-12U)
- CAS-5A, CAS-5B, CAS-7A and CAS-7C
- Jiama Shexian Bao Tance Weixing (Gamma ray burst detection microsatellite)
- Tianiy-4 (Xiaoxiang-4)
- Zhongwei-1
- Xianrikui-1A and Xianrikui-1B
- Jianyang-1
- Taihu-1
- Jinggong-1 (a CubeSat-6U)
- Xidian-1

Any help would be appreciated. Thank you!

You are talking about CZ-9 (2021) combined with boosters with YF-130s. I don't think you can just keep growing the size due to the material limit.

Version 21's diameter is 1m lager than the core stage of version 11. However the lift off masses are the same. The 1st stage of version 21 hold the same amount of fuel of the 1st stage of version 11's core and 4 boosters. The stress to the fuselage is much higher. Think about an elephant getting double weight, it won't be able to stand on its own feet.

Besides, using two types of engine for first stage is a bad idea, CNSA wants to reduce the type of engines in one rocket. The very reason of 120t LOX/LH2 engine was mentioned in version 2021 is because it can be used for both 2nd and 3rd stage unlike version 2011 in which YF-90 is used for 2nd stage and YF-79 for 3rd stage.

Landing date set around 2030!!!

From what I heard of the video, when Long Lehao said "about 2030" he was talking about two CZ-5DY launches, CZ-9 was not mentioned for that date.

Initial Chinese lunar landing will involve the use of two LM-5 rockets.

If you mean CZ-5DY aka 921, then yes. Certainly not any variant of current CZ-5.

Beside, I highly doubt the eventual designation of CZ-5DY is anything like CZ-5X. DY is just a temporary name given by Long Lehao, in his own word "I call it DY". CZ-5DY only shares the 5m fuselage technology and YF-100 engine from the CZ-5 program (including CZ-6, 7, 8), other than that it is very different. It deserves a separate number series equally as 6,7,8.
