Starlink Group 6-21
Launch Time
NET October, 2023
...
SLC-40 or LC-39A, Florida, USA

Discussion:
Will there be any non-Starlink September Florida Falcon 9 launches from Florida?  Apparently not (assuming the next mPower launch is not delayed into September).
Possibly USSF-124 if that September 29th launchdate from that recent presentation holds.
And now, O3b mPower is listed NET October, and USSF-124 is listed NET November.

So, we have wall-to-wall 🧱 September Florida Starlink launches! 🍎
O3b mPower 5 and 6 have not yet been delivered to Cape Canaveral.  USSF-124/HBTSS launches NET November.

Ben Cooper's Launch Photography Viewing Guide, updated September 22; my bold:
Quote
Falcon 9, September 23 @ between about 8:20 p.m. and 11:50 p.m. EDT (pad 40):
<snip>
The next SpaceX Falcon 9 will launch a Starlink batch from pad 40 on September 23 around 8 p.m. to midnight EDT. A Falcon 9 will launch a Starlink batch from pad 40 on September 28. A Falcon Heavy will launch NASA's Psyche spacecraft to its namesake asteroid from pad 39A on October 5 at 10:34 a.m. EDT <snip>. 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.

The SLC-40 Starlink mission following 6-19 is likely to launch at the beginning of October.  Assuming (big assumption) that SpaceX continues to launch its Florida Starlink Group 6's in ascending numerical order, this launch will be 6-21.  It is currently listed with launch NET October, from either Kennedy LC-39A or Canaveral SLC-40.

However, LC-39A is not currently available due to Psyche/Falcon Heavy launch preparations for October 5.

(Starlink 6-20 launched earlier this year from Vandenberg SFB; launch thread: Starlink Group 6-20 : VSFB SLC-4E : 7/8 August 2023 (03:57 UTC))



Starlink 6-17 successfully launched from SLC-40 on September 20 UTC, with a successful first stage landing aboard ASOG.

Starlink 6-18 is currently scheduled to launch from SLC-40 on September 24, with a first stage landing aboard JRTI.

Starlink 6-19 is currently scheduled to launch from SLC-40 NET September 28, with a first stage landing aboard ASOG.

Starlink 6-21 could launch from SLC-40 NET October 2,  with a first stage landing aboard JRTI.  (4 day SLC-40 turnaround, 8 day ASDS turnaround)
However, using Ben Cooper's information above as a guide, the launch may occur shortly after Psyche's.

The next United Launch Alliance Atlas V rocket will launch the first Amazon Kuiper Protoflight internet satellites on October 6 at 2:00 p.m. EDT. The first flight of the Vulcan rocket will use the same launch pad when it sends the Peregrine lunar lander to the moon on December TBD.

Note that this information is likely incomplete. It is very likely that there are actually two additional backup days.

NGA Space Debris notices (the same notice for two different Navigational Areas). No Rocket Launching notice yet.

Map from the NGA notice. The coordinates are in the expected order this time, identical to Starlink 6-18.

Edit:

NGA Rocket Launching notice, with the expected full set of backup days.

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.

1064.4 and 1065.4 are reserved as the Falcon Heavy side boosters for Psyche.

1072.1 is reserved for Cygnus NG-20.

1076.8 and 1073.11 may undergo modifications to become Falcon Heavy side boosters for a future launch, but are apparently still available for "single-stick" launches at the current time.

Available first stages, with UTC date of most recent recovery:
1062.16  Jul 28 (after "deep" inspection?)
1067.14  Aug 17
1081.2    Aug 26
1080.4    Aug 27
1077.8    Sep 1
1073.11  Sep 4
1076.8    Sep 9
1078.6    Sep 16 (maybe)

Edit October 4:  It's B1076.8, skipping over several boosters last used in July, August, and September.

JRTI droneship got underway from Port Canaveral last night to support the upcoming Starlink 6-21 mission.

Charter tug Signet Titan is towing.

I doubt Psyche would already be rolling to 39A, sooo . . .

Starlinks for this mission headed to pad 40 this evening.

Fairing recovery ships Bob & Doug are still in Port Canaveral.  With mission 1.5 days away, unclear whether this indicates possible delay to launch, as typically Bob/Doug depart minimum 2 days before launch.

Maybe Signet Titan underwent refurbishment that allows it to recover fairings?

[Update:  Doug departed PC on Oct 3 @ 11:39am ET (approx. 4 hour turnaround).  It's going to have to double-time it to make it to fairing LZ in time.]

L-1 weather forecast. 50% 'Go' for October 4/5. 70% 'Go' for October 5/6. All Additional Risk Criteria for both days.

Edit: Fixed the month. (I'm still in September.)

Booster B1076-8.

https://www.spacex.com/launches/mission/?missionId=sl-6-21

Quote from: SpaceX
SpaceX is targeting Wednesday, October 4 at 10:45 p.m. ET for a Falcon 9 launch of 22 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. If needed, four backup opportunities are available starting at 11:38 p.m. ET until 1:57 a.m. ET on Thursday, October 5. Six backup opportunities are also currently available on Thursday, October 5 starting at 10:29 p.m. ET until 1:49 a.m. ET on Friday, October 6.

This is the eighth flight for the first stage booster supporting this mission, which previously launched CRS-26, OneWeb Launch 16, Intelsat IS-40e, and four 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.

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