So based on the current scheduled missions going to the #ISS and need an IDA docking adapter. The earliest time there will be a docking adapter availble for the #OFT2 mission will be the 2nd half of November 2021.
So after the departure of the #Crew2 mission currently scheduled for the 8th of November, however the #Crew3 has to redock their capsule from #IDA2 to #IDA3 first. However on the 5th of December SpaceX Cargo Dragon #CRS24 needs that docking port again.
I partly blame @SpaceX here that they designed the new Cargo Dragon capsule like the Crew Dragon with IDA docking adapter instead of berthing hatch like they did with Dragon V1. The situation would be much better/flexible if only crewed vehicle would use the IDA adapters.
Also with upcoming tourist missions (Axiom, Dragon) going to the #ISS. They can only go there if no Cargo Dragon is currently docked and Cargo is a badly needed resource up there.

Per morning DPC: #OFT2 launch weather I think I understood 50% go, and the crew asked for @nasa TV to be uplinked to them so they can watch. #ISS #Exp65
Pressure on the #ISS: 752mmHg and on the Prk: 176mmHg.
Many beams, booms and brackets that were removed from #MLM #Nauka yesterday are too large to be disposed by Russian vehicles so they have to be disposed by USOS cargo vehicles. #ISS

Good morning everyone! #ISS crew is now back awake and is just having their morning DPC (daily planning conference). Seems like the activities for undocking of #Pirs will actually take place today! #Exp65 #MLM #Nauka
Russian #ISS crew members are also doing some tasks today to prepare for a potential contingency EVA if that becomes necessary after #Pirs undocking and before #Nauka docking.
Also the OPM (optimal propulsion maneuver) that actually did not take place yesterday will now take place today affecting the Ku-Band capability of the #ISS.

On board the #ISS many activities regarding #Pirs undocking have been canceled indicating that the undocking tomorrow based on the current status of #MLM #Nauka has been canceled. #unconfirmed #Exp65
Ok so the OPM (optimal propulsion maneuver) to reorient the #ISS to the undocking attitude for #Pirs is still on schedule! MCC #Houston reminded @Aki_Hoshide to close the window shutters for that during morning DPC (daily planning conference)
Since I am getting many retweets and likes on that tweet I like to remind everyone that this is just what I think I understoond on the translation loop during the morning DPC on the #ISS livestream. Let's wait everyone and see what the day holds up for us.

Upon multiple request I will try to recreate the construction of the #ISS with the recent released @LEGO_Group model in this thread (if you find any errors please let me know):
On November 20th 1998 the first #ISS module #Zarya aka #FGB was launched from #Kazakhstan with a #ProtonK rocket. It was built in Russia but funded by @nasa but operated by @roscosmos. Its purpose is cargo storage
On December 4th Space Shuttle #Endeavour launched with the 1st US #ISS module #Unity on #STS88. Shortly after launch #Unity together with #PMA1 + #PMA2 were lifted from the payload bay and docked to the shuttle docking adapter:
