This application extends information from grant 0932-EX-ST-2023.

This is an extension to the 3rd O3b mPOWER mission FCC grant (assignment is not confirmed but very likely as speculated by others). Seems SpaceX thinks this may not launch until December.

Might this extension merely be like insurance?

Also, NET December could = NET Q4 in NextSF jargon = NET November/December?
Delayed again...

Therefore:
Ben Cooper's Launch Photography Viewing Guide, updated October 9; my bold:
Quote
The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on October 9 at 8:42 p.m. or later EDT. A Falcon Heavy will launch NASA's Psyche spacecraft to its namesake asteroid from pad 39A on October 12 at 10:16 a.m. EDT. The side boosters will land back at the Cape about eight minutes after launch. A Falcon 9 will launch a Starlink batch from pad 40 on October 14.  A Falcon 9 will launch a Starlink batch from pad 40 on mid-October. Upcoming launches include more Starlink missions from pad 40. A Falcon 9 will launch the CRS-29 resupply mission to the ISS from pad 39A on November 3 at 11:49 p.m. EDT. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches from pad 40.



The SLC-40 Starlink mission following 6-24 is likely to launch in late October.  Assuming that SpaceX continues to launch its Florida Starlink Group 6's in ascending numerical order, this launch will be 6-25.  It is currently listed with launch NET November, from either Kennedy LC-39A or Canaveral SLC-40.

However, LC-39A will not be available due to launch preparations for November Falcon 9 launches.

https://nextspaceflight.com/launches/details/7243



Starlink 6-22 is currently scheduled to launch from SLC-40 from SLC-40 October 10 UTC, with a first stage landing aboard ASOG.

Starlink 6-23 is currently scheduled from SLC-40 NET October 14 UTC, with a first stage landing aboard JRTI.

Starlink 6-24 is currently scheduled to launch from SLC-40 NET October 19, with a first stage landing aboard ASOG

Starlink 6-25 could launch NET October 23, with a first stage landing aboard JRTI.  (4 day SLC-40 turnaround, 8 day ASDS turnaround)

(One  more Starlink Group 6 launch could fit in from SLC-40 before or on Nov 1.

Foul weather and sea states, including hurricanes, will break the perfect pattern.🌀 Murphy's Law.)

Ben Cooper once listed this as slipping into next month, but it looks like the next O3b mPower launch got delayed and this is back in October again:

Quote
The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on October 21 at 10:23 p.m. EDT or later. A Falcon 9 will launch a Starlink batch from pad 40 on late October. A Falcon 9 will launch the CRS-29 resupply mission to the ISS from pad 39A on November 5 at 10:01 p.m. EST. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches from pad 40. A Falcon 9 will launch the mPOWER-C internet satellites for SES from pad 40 on November, in the late afternoon EDT. A Falcon 9 will launch the NOVA-C commercial lunar lander for Intuitive Machines & NASA from pad 39A on mid-November.

NextSpaceflight, updated October 19:
NET October 25

However, Starlink 6-24 will be the previous launch from SLC-40 on the 22nd UTC.  SpaceX requires approximately 4 days to turn around the launch complex.

JRTI would be the ASDS and previously served a successful first stage landing on the 18th UTC.  SpaceX requires approximately 8 days to turn the Florida ASDS around.

Launch should be NET October 26 UTC.

Caveat: What if SpaceX succeeds at further reducing pad and ASDS turnarounds?

Edit: If a faster turnaround is to be attempted, then NET October 25 is possible.

Well..... technically JRTI's fastest turnaround between launches is 7.78d (SL 6-4 to SL-5-11).  It's fastest return time (launch to entering PC) is 2.40d (SL 6-4).  It's fastest PC in and out is 0.44d (SL 6-11 to SL 6-12).  It's shortest PC departure to launch is 2.70d (SL 6-12).  So if it maxed out all those, theoretically it could do 5.54d between launches.

Second orbit re-entry into Indian Ocean?
Therefore, launch NET Oct 28 ~23:00 UTC?



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

The May 16 press briefing revealed Falcon 9 first stages are now cleared for use up to twenty times for Starlink launches.

1064.5 and 1065.5 are reserved as the Falcon Heavy side boosters for USSF-52.

1072.1 is reserved for Cygnus NG-20.

1076.9 and 1073.11 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are available for "single-stick" launches currently.

One of the lesser-used first stages may be held for Cargo Dragon SpX-29, currently launching Nov 6 UTC.

Available first stages, with UTC date of most recent recovery:
1081.2    Aug 26 (reserved for SpX-29?)
1077.8    Sep 1
1073.11  Sep 4
1078.6    Sep 16
1058.18  Sep 20
1060.18  Sep 24
1069.11  Sep 30
1076.9    Oct 5

Edit October 28: It's B1077.8.



Will this launch also carry 23 satellites?

SpaceX is targeting Saturday, October 21 at 10:17 p.m. ET 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. <snip>

Edit October 28: Yes, 23 satellites.

NGA Rocket Launching notice and two Space Debris notices (the same notice for two different Navigational Areas).

Maps from the NGA notices. ASDS 630km downrange.

Edit: On closer inspection, it appears a small dogleg will be introduced for the booster, and that there will be a slight reduction in the already small dogleg for the second stage. Added an anigif of 6-24 vs 6-25, open the file to view the animation.
