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 3:

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. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Meteosat MTG-S1 weather satellite for Europe on early July TBA.

The next United Launch Alliance Atlas V rocket will launch the second Kuiper internet satellite batch on June 13 at 2:29-2:59 p.m. EDT.

This next Starlink launch will likely be mid June.  LC-39A will be available after turnaround from Axiom-4, but as that launch is currently delayed to June 10, this launch will likely be from SLC-40, circa June 14?

That’s way too early for a slip like that. 33 hours before the first opportunity, and now it’s automatically rescheduled for mid-morning that day.

Unless there was an orbital plane change decision made off-camera, this slip doesn’t make sense.

SpaceX is targeting Friday, June 13 for a Falcon 9 launch of 23 Starlink satellites, including 13 with Direct to Cell capabilities, to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 11:21 a.m. ET, with backup opportunities until 11:44 a.m. ET. If needed, additional opportunities are available on Saturday, June 14 starting at 7:18 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 will be the 21st flight for the first stage booster supporting this mission, which previously launched Crew-6, SES O3b mPOWER-B, USSF-124, Bluebird 1-5, and 16 Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.
