China just announced it has finished building its space station. Here is a review of 11 launch missions since April, 2021 when the in-orbit construction began and how the station named Tiangong or Heavenly Palace in Chinese looks like now. (Video not complete due to time limit)

#ChinaSpaceStation flying over #Moon!
Could you find the difference between the two photos taken on August 14th ,2022 and January 8th, 2023? You’ll see clearly that China’s space station #Tiangong has changed shape. CSS was fully completed in 2022.

Device to detect orbital particles mounted outside China's space station
Source: Xinhua Editor: huaxia 2023-01-11 18:15:45
BEIJING, Jan. 11 (Xinhua) -- A particle detector has been installed on the extravehicular platform of China's space station to obtain key data used for the space station's safety, extravehicular activities of the astronauts, biological experiments, and the study of space material.
The energy particle detector in Wentian lab has been transported via the cargo airlock cabin, assisted by a robotic arm.
The detector used a new material called CLYC for the first time in the world that can achieve high-efficient neutron detection.
The newly-mounted device can monitor the energy and orientations of high-energy protons and electrons, heavy ions and neutrons in the space station's orbit, according to the National Space Science Center under the Chinese Academy of Sciences.

I really like their uniforms, especially the vest. It's so much better than the warehouse worker aesthetic that the U.S is going for.

More plants growing aboard, seems like they're quite serious about not just shoots and small plants, but actual mature ones, including crops. As a reference, this was only ever attempted on ISS a few years back (now more routinely, yet not with as many common, useful varieties), and a handful of times in prior space stations like Mir, Salyut or Skylab:

I understand that once a germinated seed breaks the surface of the ground it will naturally grow toward the light. That's how to control plant growth direction in zero-g. But what do they do when they plant a seed? There is no detectable gravity to tell the germinated seed which way to the surface. What is the mechanism to get seeds to grow toward the surface where light can then take over?

GT: This year, only one Tianzhou cargo spacecraft will be launched to the Chinese space station.
Starting from Tianzhou-6, cargo ships have optimized and upgraded the layout of equipment and cargo holds. The improved airtight compartment cargo transport capacity will be further improved. Each launch of a fully sealed cargo ship can deliver ~3 months more food for astronauts.
The Tianzhou cargo spacecraft has a maximum take-off mass of 13.5 t, a maximum uplink cargo mass of 7 t, and a propellant replenishment capacity of 2.5 t.

That's actually a great question that's the subject of ongoing, well-seasoned research dating back decades! It's called gravitropism and phototropism, and it's still poorly understood - researchers have been able to rule out several mechanisms, but not really pin down the correct one. They have even developed mutant plants without the organules needed to sense direction, and still found a response, suggesting something deeper going on - like an integrated mechanism, sensing of local density or irrigation gradients... Here's a good recent review: https://www.mdpi.com/1422-0067/23/18/10548

Zero-G enables you to grow them at fractional Gs too, through centrifuges. Can't really do that on a 1G+ gravity well except for short periods of time.

Astronauts on ISS (plus probably those on CSS soon too, if not already) routinely eat vegetables grown and matured in space, providing them not only with an experiment, but with actual supplies, wellbeing through gardening and tendering to a living being, and some would say even decoration. It has also happened, even if in a more anecdotal fashion, in prior space stations beginning with Salyut 6 in 1975 (onions, of all things :) )

Regardless, that's the value of fundamental research: you might not be looking at immediate application, but to widen knowledge, in this case about plant biology and behavior, which can on the other hand prove useful even to phenomena on the ground(s).
