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.

It's sad there are people who still downplay China's advances and accomplishments, even when evidence to the contrary is there for everyone to see.

A cold-launch space launch from a ship should have EVERYBODY's attention.

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）

@cattalonX : Obviously whole paper translation it's impossible, but a few lines summary is more than welcome.

Thank you very much

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

That's what uncontrolled re-entry gets you: the neighbours poking at bits you don't want to be poked at.
There's a lesson to be learned here, unfortunately the Chinese government thinks the lesson is that piracy is the way to solve this.

Chang'e 6 is a backup package for Chang'e 5. Since the former succeeded they have to reuse it somehow.

I mean afaik they technically had a "space station" already. Even that by itself was a huge accomplishment. They just lauched their first "taikonout" into space 16 years ago but look at where they are now.
