My bolds; Florida Starlink launches resume after SXM-10 and Axiom-4 launches, from both LC-39A and SLC-40.

Ben Cooper's Launch Photography Viewing Guide, updated May 17:

The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on May 19 at 11:40 p.m. - 12:15 a.m. EDT. A Falcon 9 will launch a Starlink batch from pad 40 on May 24 at 1:24-5:24 p.m. EDT. A Falcon 9 will launch the next GPS satellite for the U.S. Space Force from pad 40 on late May TBA. A Falcon 9 will launch the Sirius XM-10 broadcasting satellite from pad 40 on June 6. A Falcon 9 will launch the Axiom-4 spaceflight participant mission to the International Space Station from pad 39A on June 8 at 9:11 a.m. EDT. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Meteosat MTG-S1 weather satellite for Europe on July TBA.

Ben Cooper's Launch Photography Viewing Guide, updated June 5:

The next SpaceX Falcon 9 rocket will launch the SiriusXM-10 broadcasting satellite from pad 40 on June 6 at 11:19 p.m. - 3:19 a.m. EDT. A Falcon 9 will launch the Axiom-4 spaceflight participant mission to the International Space Station from pad 39A on June 10 at 8:22 a.m. EDT. The first stage will land back at the Cape about eight minutes after launch. A Falcon 9 will launch a Starlink batch from pad 40 on June 10 at 9:03 a.m. - 1:03 p.m. EDT. A Falcon 9 will launch a Starlink batch from pad 40 on June 13 at 7:45-11:45 a.m. EDT. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Meteosat MTG-S1 weather satellite for Europe on early July TBA.

This next Starlink launches will likely be mid June.  LC-39A will be available after turnaround from the June TBD Axiom-4 launch, and this launch could also be from LC-39A.  Further Axiom-4 delays place LC-39A next availability TBD.

Or, near-simultaneous launches from LC-39A and SLC-40.

Pad turnaround about 2 days? Possible? Record? or likely delay?

Pad turnaround about 2 days? Possible? Record? or likely delay?

Likely delay by at least 24 hours. I don't know if SLC-40 is capable of a sub-48 hour turnaround yet or not.

Likely delay by at least 24 hours. I don't know if SLC-40 is capable of a sub-48 hour turnaround yet or not.

The current record for SLC-40 turnaround is 2 days, 9 hours (Starlink Group 12-16 --> Starlink Group 12-21). This would break that record by 8 hours.

My bolds:

SpaceX is targeting Sunday, June 22 for a Falcon 9 launch of 27 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 1:47 a.m. ET [05:47 UTC], with backup opportunities available until 5:47 a.m. ET [09:47 UTC]. If needed, additional opportunities are also available on Monday, June 23 starting at 1:25 a.m. ET.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This is the 25th flight for the first stage booster supporting this mission [1069-25], which previously launched CRS-24, Eutelsat HOTBIRD 13F, OneWeb 1, SES-18 and SES-19, and 20 Starlink mission. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.

Probability of violation, local weather: 5%

[Steven Pietrobon]

Scrub at T-58 seconds [to the 05:57:10 launch time]. Aborted due to poor FTS signal. Next opportunity is on Monday, 23 June at 1:25 am local (05:25 UTC).

[ZachS09]

It's important to have a good FTS signal at all times.

Falcon 9 (and Falcon Heavy) may be reliable, but the vehicle may need to be terminated if a bad-enough anomaly could doom its mission.
