Oh wait, one more very cool thing: micro/nanosats deploying system through the robotic arm.

Mengtian also has 37 standard exposed payload adapters. See the quoted tweet for more info of the research facilities of China Space Station..

The Advanced Resistive Exercise Device (ARED), which replaced the interim version in 2009, allows intensive workouts for astronauts on ISS. The China Space Station #Tiangong will also have a similar one later this year after the docking of Mengtian module.

What would you name this? CSS Max Pro? (The additional laboratory modules are missing service modules.)

China is close to completing an entire space station in a little over 18 months. Could do without the uncontrolled re-entries but it is impressive none the less. First crew rotation is scheduled to happen later this year and its telescope companion is launching next year!

Models of the China Space Station is currently being set up at Zhuhai Airshow. Here we have two photos of the assembly of the real modules in CASC's testing facility.

Does anyone here know the current status of the backup modules?

If they were going to fly for CSS expansion, how long would it take to make them ready?

That highlights just how different the CSS relocation arm is from Lyappa: not only is the motion axis different (planar move rather than angled rotation) but the CSS arm entirely skips the extend/retract function of Lyappa:
- Lyappa must grasp a module, wait for the probe to disengage and retract, then move the module away form the docking port, then rotate it to the new position, then move the module back towards the docking port, then the probe is extended and reengaged before docking can complete
- the CSS arm waits for the APAS-like port (does this have an official designation?) to disengage the hard latches then move the module to the standoff distance by extending the soft capture ring. Only then does the arm grasp the module, which then waits for the soft capture ring latches to disengage and the soft capture ring to retract before translating it to the new location. Then, the arm remains stationary whilst the soft capture ring extends and latches, at which point the arm releases the module and the module approaches and hard latches as it would for a free approach.
It eliminates an entire degree of freedom from the arm and uses existing hardware present for docking to perform fine location and translation instead.

I have seen several people here state with confidence that the Chinese docking system is IDSS compatible, and several people state with equal confidence that is is not.

I have no idea which is correct.

It's safe to simply call it the Chinese Docking System.
