BeaverCube II 3U CubeSat scheduled to be transported on this flight.
0963-EX-CN-2022

NASA's Microgravity Research Flights website is showing a 2023 Jan launch for CRS-27.  With the busy ISS schedule (CRS-26 arriving Nov 22, Crew-6 arriving Mid Feb, Boe-CFT in Apr, AX-2 in May), would they really consider sending up Cargo missions only 2 months apart?

Potentially due to IROSA weighing so much?  Or need extra supplies for all the extra visitors?

I don't know about range conflict, but it they want to overlap Crew-5 and Crew-6, then SPX-27 will need to wait until Crew-5 undocks, since there are only two IDSS-compatible docks on ISS, right?

Possible that this goes in January considering that both NxSF & NASA are showing NET Jan

USSF-67 NLT January 10; that would place this launch NET late January?

“We’re launching two satellites within 70 days of one another, which is fantastic from a program perspective,” Rupp said.

This implies that the USSF-67 launch target is no later than January 10th.

NET February 2023

Crew-6 is now scheduled to launch February 19 from LC-39A.

ViaSat-3 Americas is now scheduled to launch NET March from LC-39A.

SpX-27 could launch before or after Crew-6.

Way before. I believe At least 1+ month till Crew launch. Cargo Dragon 2 spent on average 33 days on ISS. Now NASA extended to (I believe) 45 days?  I don't think that NASA would drop docked duration to lower then a month. So in this case SpX should lauch CD till 1st half of January.
I think safe to say that this launch will occure in few days after return of Crew 5. ISS need more docking ports for Dragons.

Capsule is C209-3. Its last flight was in December 2021, making the time between launches of one year and two months.

There is, apparently, not enough time to complete a Cargo Dragon mission between February 1 and 19.

There are two docking ports for Dragon spacecraft, and one must be open for Crew-6 to dock.

And, there must be enough days for effective crew turnover--8 days seems sufficient.

This would set SpX-27 launch to NET February 28, docking March 1.

That is the chain of reasoning, I  believe, that one sees in Salo's schedule calendars.
