There's a very detailed schedule of all the launches to Tiangong.

Here's the Bing translation of the schedule. I corrected some of the spacecraft numbers. Well that was fast, the tweet has now been made private!

Schedule for the construction of our space station:
2021.04.29: CZ-5B Y2 launch core module;
2021.05.20: CZ-7 Y3 launch tianzhou II;
2021.06.10: CZ-2F/G Y12 launches Shenzhou XII
2021.09: Shenzhou XIO returns, CZ-7 Y4 launch tianzhou III;
2021.10: CZ-2F/G Y13 launch shenzhou XIII;
2022.03: Shenzhou XIII returns;
2022.03-04: CZ-7 Y5 Launch Tianzhou IV;
2022.04: Evaluation of critical technology validation of the space station;
2022.05: CZ-2F/G Y14 launch Shenzhou XIV;
2022.05-06: CZ-5B Y3 Launch QuestionIng Laboratory Module;
2022.08-09: CZ-5B Y4 Launch Dream Day Experimental Module;
2022.10: CZ-7 Y6 launch of Tianzhou V;
2022.11: CZ-2F/G Y15 launch Shenzhou XV (will be docked with Shenzhou XIV for 10 days, when the number of people in orbit will reach 6).

So is SZ14 to be in independent flight during the docking of Wentian and Mengtian? And would they leave Wentian at the forward docking port until Mengtian arrive so to keep things mostly symmetrical?

I think that the crew of SZ-14 will assist the docking of the two modules within the station.

I suppose we will see an 'L-shaped' station for some time. Wentian will dock on the axial port and then be moved to a lateral port shortly before Mengtian launch. Then Mengtian docks also on the axial port and will be moved to the lateral port opposite do Wentian. Just like has been done on Mir.

With SZ-15 docked at the same time as SZ-14, this looks to be the first Tiangong crew station rotation.

From the video Tian He (pronounced tian hur) mass is 22.5 t. Altitude 400 km. Tian He has 50 m³ internal volume. Minimum crew is three, but can sustain 6-7 crew. Uses UDMH/N2O4 propellant to maintain orbit. The silver domes are covers for viewing ports (css-02). Exercise bike (css-03). Main lab (css-04). Can hold 8 t of propellant. Total mass is 62 t with Wentian, Mengtian and Shenzhou. Working with UN and 80 other countries for microgravity experiments. Has robotic arm. Space toilet (css-08). Looks a lot like the Shuttle toilet. Food pack (css-09,10). CSS could carry a robot in the future. Astronaut tilt table (css-11). EVA suit (css-12).

Much more probably that css-02 shows the gyroscopic attitude control set -- six gyrodynes.

Yes, you are right. These are one of the six gyroscopes. There are two small round windows (portholes) on port and starboard. And maybe in some doors of the docking ports.

Here is a a nice chart with labels I posted also in then Tianhe thread:

Tian He has 50 m³ internal volume.

That seems a little on the small size for a module of this size and configuration, and the interior shots that we have seen.  the roughly similar Mir  base block was ~100 m3, Salyut 6 and 7 ~80, I think.

I wonder then if this refers to habitable rather than pressurised volume?

50m3 is the habitable volume which refers to the narrow part of the module, the wider part got 90-100m3, makes it a combination of 150m3 pressurized volume.

The second video shows Shenzhou docking to a nadir port, while two Tianzhou spacecraft are docked to the aft and forward ports. This could be for Shenzhou 13.

Xuntian space telescope

Is there any information about how this free-flying telescope will attach to the station for servicing? Does it have a docking adapter, or will it be grabbed by the station arm? (I presume the latter)

So questioning ESA astronauts going to the Chinese station is against the rules now?
