China just launched a rocket with 5 satellites to orbit from a platform at sea

It was the second launch in 2 days for China.

The question why ?
Normal is this used in ICBM or SLBM ejection from it Silo
was Long March 11 a ICBM project that ended up or tested as Launcher ?

on Long March 9 current version
They building a Chinese version of Saturn V and its reusable !

This here quite interesting news
until now China got there ion engines from Russia, not anymore !

It's too hard for me to translate a whole paper··········
Basically, this paper discusses several types of lunar landers with different fuels
The screenshot shows the lightest version of the liquid hydrogen and oxygen fuel
The lander weighs about 25 tons and can be launched on the planned CZ5G rocket（TLO 27tons）

The difference is that the Chinese lander landed and took off in single-stage，That is the biggest problem，When they land, they have to conserve the fuel they used to take off···········So you can carry less cargo
