Reply to comment by rshorning in China hoping rocket that can send people to the moon will be ready to launch by 2027 by Saltedline

I'm not trying to take anything away from Apollo. But there's no reason the Chinese can't basically follow the Apollo playbook while adding improvements from the last 50 years of spaceflight. You keep talking as if they are so far away. They have landed on the moon and returned already. They just need to scale it up to include humans, which involves solved engineering problems. It's not easy or cheap but it's well within their mid term capacities.

Which in turn would require dozens of test flights to get that capability.

NASA is still close to a decade away from being able to duplicate the Apollo 17 mission. And they went to the Moon in 1969. This is not trivial nor easy and even NASA is going to be doing several test flights before actually landing. Why should CNSA be taking even fewer steps and being throwing caution to the wind for what is obviously an incredibly difficult task?

It is not trivial to include crewed spaceflight. You completely miss the technical and engineering problems involved. Nor even really realize what was actually learned from Apollo and some pretty bad mistakes NASA made that could have and should have been fatal except for just plain dumb blind luck. These engineering problems are not wholly solved and really is something akin to creating an epic national monument that will be remembered for millennia to come. Like the Pyramids of Giza.

I am not saying this is impossible, but I am saying that it will take far more than you give credit here and these issues are incredibly daunting simply to return to the Moon by any nation. And China needs to develop this capacity themselves that they simply don't have right now. Copying and pasting engineering plans from another country simply isn't going to cut it here with this particular task.

Of course there will be test fights involved in any program. No reason why it would take dozens. Several, like the Artemis program, is probably what we should expect.

>NASA is still close to a decade away from being able to duplicate the Apollo 17 mission.

NASA is not trying to duplicate Apollo. If they were they would be much closer.

I feel like at this point we are saying fairly similar things. There are engineering challenges that China is likely capable of solving in the medium term. We agree it's not necessarily easy but it also doesn't require any new breakthroughs.
