- Solar panels smaller in area than ISS but produces similar amount of power, indicating much more efficient solar panels
- Ion thrusters to keep space in orbit
- Automated docking of cargo and crew capsule. Semi-automated docking of large station components like the 23ton labs
- A robotic arm similar to ISS that walk along the joint points on the station. It has expandable attachment system, allowing not only astronauts to attach, but also a smaller more precises robotic arm to attach that can manipulate external experiments.
- It has a crew airlock and a cargo airlock, the cargo one is larger than the one on ISS.
- It can also release small satellites through the cargo airlock.
- Dozens of external experiment attachment points, some (maybe all) has power and control
- What looks like pretty good communication links with the ground. Experiments can be controlled and monitored from the ground, saving astronaut time.
- What looks like some advanced experiment equipment, including three very accurate atomic clocks, near absolute zero cooling systems etc. But I am not well versed in physics to speak on these.
- It will operate a space telescope; telescope can dock with the station for servicing and upgrades, and equipment uploaded by regular space station cargo ship.
I think it is a well-designed system, surprisingly capable in terms of research capabilities. As China's space industry is completely sanctioned by US and Wassenaar Arrangement, all technology here are from Chinese industries and local supply chains: materials, precision manufacturing, communication equipment, sensors used for guidance/automated docking, robotic arm, ion thrusters, solar panels, networking and control system within the station, even to the logistic system of building, launching and running the station. Then there is the whole rocket system themselves, 100% success rate thus far with CZ-5/B, CZ-7 cargo ship, and Shenzhou launch vehicle. And then the global positioning and communications satellite network. And then there is the whole research equipment part. There are millions+ ppl involved in all of the projects here.
