Project 921 aka CZ-5DY has now taken on the designation of CZ-10, or Long March 10 rocket. CZ-10 will be a rocket for lunar mission sending manned spacecraft and lander into LTO. Full length 88.5 m, take off mass 2187 ton, take off thrust 2678 ton, thrust to weight ration 1.22, LTO capacity 27 ton.

The lunar mission CZ-10 will have two boosters. There will be a derivative without the booster which is used for LEO space station manned and cargo mission. The CZ-10 for space station mission is full length 67 m, take off mass 748 ton, take off thrust 873 ton, LEO capacity 14 ton. The first stage will be a reusable stage.

Project 921, now the CZ-10.

Project 921 previously dubbed as CZ-5DY. The version with the booster stage, CZ-10, is intended for lunar mission. A version without the booster stage, consist of the first and second stage of CZ-5DY or CZ-10. If its first stage will be resuable, I suspect the CZ-10 first stage will also be reusable.

The next generation manned spacecraft for lunar mission has a new design exhibited.

The lunar spacecraft I think will be around 25 tons, not including the lunar lander, which I expect will be launched separately by CZ-10. I presume only CZ-9 will have the capacity to launch both launar spacecraft and lander in a single launch with its LTO capacity of 53 tons.

The current next generation spacecraft conducted first test flight in May 5, 2020, launched by CZ-5B. It marked the beginning of the Chinese manned lunar programme.

A comparison of the tested next generation spacecraft versus the lunar spacecraft. This year we may see a test flight of the next gen spacecraft again, not sure of which design.

YF-130 intended for CZ-9, successfully conducted a full engine test in Nov 5, 2022. It is the highest thrust engine developed at 500 ton. This is a major milestone for CZ-9.

YF-209 is an 80 ton methane LOX engine in development. It's a reusable, low cost and high performance engine intended for use in reusable rocket. Currently it's not announced where it'd be used.
