SpaceX F9 : Starlink v1.0 L17 : KSC LC-39A : 4 March 2021 (0824 UTC)

[LouScheffer]

Should be enough room on the deck to have 2 boosters on at once.  Never would happen but I suspect its technically feasible.

I'm sure this has already been discussed to death in another better thread but this is one of those cases where it would just be insane without making substantial changes. Most notably, SpaceX would need to secure the stage with Octagrabber, move it to a corner, remove Octagrabber, and safely secure the stage again with jacks and shoes. Even then, in the event that the second booster lands but is hit by sea conditions that prevent recovery and leave it sliding around, two boosters would be at risk. Almost impossible to imagine SpaceX risking two landings on the same ship in with the current operational regime and fleet as-is.

But again, please discuss this concept elsewhere unless it becomes clear that it's actually SpaceX's plan for JRTI and B1051.

Both of you are right.  It's technically feasible (the accuracy is good enough) but has practical problems after the landing.  Previous discussion is here.

This would greatly increase the turnaround time on the booster and ultimately be counterproductive to the long term launch cadence.

I don't disagree on any of those points.

My message was simply to address JRTI being able to leave the LZ and get back in time for another Starlink launch on the 27th.

Clearly, the obvious answer is going to be, delay from the 27th.

Agree, it will likely be delayed a few days. 

LOL, maybe one of the first jobs for the new platforms is to just sit on the starlink LZ and catch F9's and off load multiples of them horizontally onto a ASDS for return.

There is quite large window for possible delay of Starlink v1.0-L17 mission between 27 Jan to 03 Feb according to issued NOTAM in Melbourne and Mauritius FIR for Stage2 debris reentry.
Such reentry area correspond again for double Stage2 burn with circular deploying orbit.

JRTI and Hawk are still at the LZ, so this pretty much guarantees the 27th is not happening.

Apparently, we are in the midst of a Starlink-Launchapalooza!

EDIT February 2: Two Falcon 9 launches on February 4, pre-dawn EST!!!

[vaporcobra]

If JRTI or OCISLY are unable to turn around and depart tonight or tomorrow, it's safe to assume Starlink-17 is going to slip. For reference, JRTI and its tug left Port Canaveral on the evening of Jan 13 when Starlink-16 was still scheduled around 8am Jan 17, so we're likely already into the cutting-it-close zone with JRTI still in port this evening.
