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)

I believe it has both and even a small compartment at the back that can be pressurized for instrument replacement/servicing. See the Twitter thread bellow for good introduction to it:

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

Somehow I feel that this is unlikely to happen on both sides given their relationship lately and that the co-operation on HSF has yet to happen unlike the case of the Russians.

The general scheme reminds me of astronaut-tended Marshall Space Flight Center / Apollo Applications era proposals. (Precursors to the Hubble Space Telescope, activities that a space station could support.)

I'm curious to see if that is what they actually do. If you think about it, that could create some major design headaches, because if the instruments are contained in a pressurizable compartment, then they have to be isolated from the vacuum. If an astronaut pulls out an instrument, it cannot open up a hole that allows the air to escape. It might make more sense to do all of that servicing unpressurized.

Pressurized servicing was considered in some NASA telescope designs in the late 1960s, but that was abandoned.

Great resource! I wonder though if Tianzhou 2 and 3 docked operations overlap how Shenzhou 13 can dock to an axial port, since both are occupied. Does it mean nadir port maybe instead (as this is the other one for Shenzhou docking operations)? Edit: nadir port confirmed by graphics and videos

Based on this infographic and NET dates published on Twitter I constructed this guesstimated current timeline of upcoming CSS operations:

May 29 at ~12:55 UTC - launch of Tianzhou 2 on CZ-7
May 30 at ~19:30 UTC - docking of Tianzhou 2 with aft port of Tianhe
June 17 - launch of Shenzhou 12 on CZ-2F/G
June 18 (NET) - docking of Shenzhou 12 with forward port of Tianhe
August (NET) - undocking of Tianzhou 2 from aft port of Tianhe for rendezvous testing
September (NET) - undocking from forward port & landing of Shenzhou 12
September (NET) - docking of Tianzhou 2 with forward port of Tianhe for propellant transfer testing
September (NET) - launch of Tianzhou 3 on CZ-7
September (NET) - docking of Tianzhou 3 with aft port of Tianhe
October (NET) - launch of Shenzhou 13 on CZ-2F/G
October (NET) - docking of Shenzhou 13 with nadir port of Tianhe
October (NET) - robotic arm relocation testing of Tianzhou 2 (to side port?)
October (NET) - undocking of Tianzhou 2 from forward (side?) port of Tianhe for EOM & reentry
March (NET) - undocking from nadir port & landing of Shenzhou 13
March (NET) - undocking of Tianzhou 3 from aft port & docking at forward port of Tianhe
March/April (NET) - launch of Tianzhou 4 on CZ-7
March/April (NET) - docking of Tianzhou 4 with aft port of Tianhe
May (NET) - launch of Shenzhou 14 on CZ-2F/G
May (NET) - docking of Shenzhou 14 with nadir port of Tianhe
May (NET) - undocking of Tianzhou 3 from forward port of Tianhe for EOM & reentry
May/June (NET) - launch of Wentian on CZ-5B
May/June (NET) - docking of Wentian at forward port of Tianhe

After this it gets a bit murky as Tianzhou 5 operations seem to overlap with Tianzhou 4 but there is no free docking port? But maybe TZ-4 will undock before TZ-5 arrives as it was scheduled (according to Twitter) to fly only in Oct. 2022?

July? (NET) - undocking of Tianzhou 4 from aft port of Tianhe for EOM & reentry
July? (NET) - launch of Tianzhou 5 on CZ-7
July? (NET) - docking of Tianzhou 5 with aft port of Tianhe
July? (NET) - robotic relocation of Wentian from forward to starboard on Tianhe
August/September (NET) - Mengtian launch on CZ-5B
August/September (NET) - docking of Mengtian at forward port of Tianhe
September? (NET) - robotic relocation of Mengtian from forward to port on Tianhe
November (NET) - launch of Shenzhou 15 on CZ-2F/G
November (NET) - docking of Shenzhou 15 with forward port of Tianhe
November (NET) - undocking from nadir port & landing of Shenzhou 14
December? (NET) - undocking of Tianzhou 5 from aft port of Tianhe for EOM & reentry

In the last few days, I came across a Chinese-source presentation detailing international contributions to the China Space Station, but I cannot find it again. Does anyone have an idea which document this could be?

Might it be this one: https://www.unoosa.org/documents/doc/psa/hsti/CSS_1stAO/CSS_1stAO_Handbook_2018.pdf ?

I'm afraid not but thanks.
The one I am looking for actually mentions international partners in specific research, along with their national flags...

Maybe you're talking about the beginning of this video posted above?
