General
Some slides on the XZY-1 launch vehicle from Arrowhead/Space Epoch and the company's future plans.
Specs:
– Payload to LEO: 6.5 tons
– Reusability: 20 times
– Length: 64m
– Fairing diameter: 5.2m
– Stainless body, splashdown recovery
The company aims to have the capacity for 25 XZY-1 launches annually. First-stage splashdown recovery test will be carried out in June of 2024, to be followed by a sub-orbital splashdown recovery in December of 2024. The company aims to achieve full reusability by the end of 2026.
Beijing Arrowhead/Space Epoch has with Suzhou Shifang (十方星链) to launch Shifang's medium orbit relay satellite constellation and to cooperate in developing measurement and control technologies.
this is a big news.
Now we have 3 huge LEO constellations from China, including 2 from Shanghai. This is needed to prevent SpaceX and Starlink from dominating the space

LEO would be so crowded, soon will be over 100,000 satellites flying around ... well that what most people would say
LEO area is huge and considering 3D which is between around 500 kms to 2,000 kms.
Earth Area is ~500 Million km2, so if the space vertical is 10 kms, we can get at least 150 x 500M km2 = 75B km2 area (remember the area of space above the Earth 500 km is even bigger than 500M km2)
So, no ... it won't be crowded ..
The satellite is small enough when it falls, it will burn quickly and left nothing when reach the land
But I do agree, we need international rules (body) perhaps under the UN, and no countries should dominate the "body" including the US and China
Any update regarding Chang'e 6 and when its landing?
The specific landing location of Chang'e 6 has been revealed by the media.
It is located at 42.1° south latitude and 154.4° west longitude on the far side of the moon.
After a successful landing, Chang'e-6 will start 48 hours of sampling on the far side of the moon . The sampling will be done by drilling and surface sampling.
As the name suggests, surface sampling means collecting soil from the far side of the moon using a shovel shaped like a human hand.
The drilling process is to drill 2 meters deep into the interior of the moon to obtain lunar soil cores.

Another way to think about it is that there are about 8000 airplanes in the sky at any given time, and they all fly in a narrow altitude band 30k to 40k feet. So 100,000 much smaller objects like satellites over a much bigger volume of space would be ok I assume.
