China's Space Program News Thread

Using other satellites' mirror diameter to proclaimed resolution, and adjusting from their orbit heights to a GEO, i'm indeed getting around 10 - 15 meters for ground resolution, if the mirror is indeed 1.7m in diameter. A 2 m mirror might yield even somewhat better results.

But measurements based on the reference points on those low res CG depictions of the satellites might be quite off. The mirror might easily be smaller than 1.7 m.

Some images of a PowerPoint presentation from the China Space Conference last month. These concern China's future manned space program.

The first slide concerns the manned moon landing. A new generation manned rocket (rumored code name 921) is very large; Wenchang launch center is being considered as the launch site. Command, control, and communications system/network have three tiers: near space, deep space, and a "Moon Relay Navigation Constellation". The return landing will be on land and on sea; a sea landing site will be set up.



The slide below shows the design of a very large lunar rover, or a roving laboratory. In the illustration on the right, it can be seen mounted at the very top. You can see two of the wheels sticking out, as well as what appear to be three forward facing windows. The roving lab is completely enclosed and can support multiple astronauts on a multi-day mission across the lunar terrain.


The space suit for doing the obligatory moon walks:



This slide is on the roadmap for reusable space planes. I can't be sure, but it appears to show two distinct systems for different purposes:
1) The top one is a transport plane that can reach any corner of earth in one hour. I call this an earth-to-earth spaceplane. Apparently, VTVL has been chosen as the starting point, as it's the most technically feasible at this point.
2) The bottom one is a "space-to-earth" transport plane.



This is a technical overview and breakdown of the various technologies required for the "earth-to-earth", "space-to-earth", and "orbital transfer" systems. Someone please do a more detailed translation as my technical Chinese is limited.

This slide is a bit confusing to me. The mobile lab is attached on top of the command and resource modules combo. The combo are for crews to fly to and return from moon. None of them are going to land on the moon surface. The mobile lab seems not able to land on itself, so there must be another lander module for it. The lander is not in this slide. For safety reasons the crew will land on moon surface separately from any cargo including the lab. The lab will land on top of another lander. There is no reason to dock them together in any orbit regardless how they get into lunar orbit.

Unless, what we are seeing (the command and resource modules) are actually lander for the lab. But then that thing really don't look like any lander.

Do you have more slide from the event? Maybe there is something to explain. Or the author was just lazy to make things look right.
