Thread for the Starlink 6-54 group launch.

NSF Threads for Starlink 6-54: Discussion (https://forum.nasaspaceflight.com/index.php?topic=60737.0)

Launch 28 April 2024, at 22:08:00 UTC (6:08 pm EDT), from CCSFS SLC-40, on booster 1076-13.  The first stage successfully landed aboard Just Read the Instructions.

Payload 23 Starlink V2 Mini satellites to 43 degree inclination orbit on a southeastern trajectory.  Initial orbit 285 x 293 km.

Well more NOTAMs for yet another Starlink launch from the Cape has been filed...and it's Group 6-54 that was never explicitly filed with the FCC (but which a recent "generic" communication license has been granted for such launches).

The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on April 18 at 6:40-10:40 p.m. EDT. A Falcon 9 will launch a Starlink batch on April 22 at 6:40-10:40 p.m. EDT. Upcoming launches include more Starlink batches. A Falcon 9 will launch two Galileo navigation system satellites for Europe on April 28. Upcoming launches include more Starlink batches.



Near-term pad availability places the launch from Canaveral SLC-40.

Near-term ASDS availability places the first stage landing aboard ASOG.

The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on April 22 at 6:40-10:40 p.m. EDT. A Falcon 9 will launch a Starlink batch from pad 40 on April 26 around 7-11 p.m. EDT. A Falcon 9 will launch two Galileo navigation system satellites for Europe from pad 39A on April 28. Upcoming launches include more Starlink batches.



Which first stage will be used for this launch? (semi-rhetorical question)

Falcon 9 first stages are now apparently cleared for use up to twenty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

1064.6 and 1065.6 are the Falcon Heavy side boosters for Europa Clipper.  1072.1 and 1086.1 are assigned as the Falcon Heavy side boosters for GOES-U.

1073.15 and 1076.13 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are currently available for "single-stick" launches.

Available first stages, with UTC date of most recent recovery:
1078.9    Mar 25  Starlink 6-53
1076.13  Mar 30
1067.19  Mar 31
1069.15  Apr 5
1073.15  Apr 7     (maybe)

Edit April 26: It's B1076.13.

I highlight JRTI's turnaround for Starlink 6-54:
Signet Warhorse III + JRTI + B1078 returned to PC on Apr 25 @ 6:16pm ET

Doug + JRTI departed PC on Apr 26 @ 12:47am ET

And, via www.marinetraffic.com , I note ASOG is in port, tucked in the harbor "cul de sac" to the camera-left of the three cranes in the usual field of view of the NSF Space Coast camera watching Port Canaveral. 👀

Two screen captures from the NSF camera: zoom of JRTI departure allowing reading of Marmac 303, dockside several hours later during morning twilight.

Just Read the Instructions droneship and support ship Doug departed Port Canaveral overnight to support the upcoming Starlink 6-54 mission.   

Another insanely fast turnaround for JRTI.

Booster B1076-13

Quote
SpaceX is targeting Sunday, April 28 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 5:50 p.m. ET, with backup opportunities available until 9:50 p.m. ET. If needed, additional opportunities are also available on Monday, April 29 starting at 5:25 p.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 13th flight for the first stage booster supporting this mission, which previously launched CRS-26, OneWeb Launch 16, Intelsat IS-40e, O3b mPOWER, Ovzon 3, EUTELSAT 36D, and six Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

Up first, Falcon 9 will launch the European Commission’s Galileo L12 mission on Saturday from pad 39A.

Then on Sunday, a Falcon 9 launch of 23 @Starlink satellites from pad 40.

Some reusability stats for this launch (Starlink Group 6-54):

Booster B1076.13 turnaround time:
29 days 0 hours 16 minutes
(its previous mission was Eutelsat 36D on Mar 30, 2024 UTC).

Out of the six most recent launches, four had a booster turnaround time of less than 30 days, marking another SpaceX achievement in the terms of reusability.

FYI: median turnaround time for Falcon 9 / Heavy boosters is currently 39.80 days *
* – based on the last 30 launches, excluding new first stages.

Launchpad SLC-40 turnaround time:
4 days 23 hours 51 minutes
(the previous launch from this pad was Starlink Group 6-53 on Apr 23, 2024 UTC).

FYI: median turnaround time for SLC-40 is currently 5.08 days *
* – based on the last 30 launches.

The same type of stats for previous SpaceX launches may be found on this spreadsheet (https://docs.google.com/spreadsheets/d/1WwD3CzpKR6vNgYS3QlxoOK9WLi81fof9zRiXzGCnbwo/edit?usp=sharing) online.
