China doesn't need to advance when US is going back in time.
This discussion is a bit heated for my taste but I will just say that if you are looking at SpaceX and what they are doing with Falcon 9 and especially Starship, and comparing that to the timelines for Chinese equivalents for super-heavy launch vehicles, you would be delusional not to be at least somewhat concerned. I think that the fact that the Chinese space program has an excellent record is something to be proud of, but I worry that this has their dampened appetite for risk. At the same time, calling Chinese space programs decades behind, while ignoring projects like Tiangong and Beidou, which are objectively more advanced than foreign equivalents, is very disingenuous.
Okay this is getting ridiculous.
We've had this conversation before.
Everyone's asked you nicely multiple times.
Have a break for a month.
The pioneer part is not exactly true. There were groups in the US, USSR, and Germany working on liquid rockets pre-war.
In the 1920s you had Goddard in the US. He was underfunded and considered a kook back then. He still built the first liquid rocket which flew up 100m. In in the 1920s in Germany you had Hermann Oberth's group. Which is where Werner von Braun came from. In the 1930s you had GIRD in the USSR. Which is where Glushko and Korolev come from.
But you are correct in that the US and USSR both benefited from the help of Nazi engineers. In the US like I said Goddard was poorly funded. He also insisted on using gasoline as a fuel and because of that his rockets kept blowing up. In the USSR GIRD focused on making rocket planes. During Stalin's purges immediately pre-war the GIRD was purged as it was seen as a waste of state resources on something that wouldn't be useful. It was basically only in Germany that consistent state funding was made available when Hitler got into power and he was demonstrated a rocket engine in action. That is also one reason why people like Werner von Braun rose and Hermann Oberth fell by the wayside. Because Oberth he was from Austro-Hungary where today is Romania the Nazis pushed him out of the program.
When WW2 was over the US and the USSR were probably like a decade behind the Germans in liquid rocket design. The first thing they did was replicate the V-2 rocket to assimilate its technology. And then more complex rockets were developed using the technology.

An that explores possible methods used for mapping a lunar lava . It's proposed that three rovers carry out the mission. A mother rover carrying two small rovers approaches the lava tube and maps its entrance. The mother rover then releases the two small rovers to explore the interior of the tube. One of the small rovers is tethered to the mother rover by a wire, which provides the small rover with both power and communications. The other small rover is a hopper+crawler combo that lands on the bottom of the lava tube and then proceeds to map the interior using lidar.
