SpaceX F9 : Starlink group 6-83 : KSC LC-39A : 13 May 2025 (05:02 UTC)

[zubenelgenubi]

Thread for the Starlink Group 6-83 launch.

Launch 13 May 2025, at 05:02:20 UTC (1:02 am EDT), from KSC LC-39A, on booster 1067-28.  The first stage successfully landed aboard Just Read the Instructions.

Payload 28 Starlink V2 Mini satellites, to a 42.99 degree inclination orbit on a southeastern trajectory.  Initial orbit 269 x 278 km.

Ben Cooper's Launch Photography Viewing Guide, updated May 3:

The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 39A on May 4 at 4:48-8:48 a.m. EDT. A Falcon 9 will launch a Starlink batch from pad 40 on May 5 at 8:48 p.m. - 12:48 a.m. EDT. A Falcon 9 will launch a Starlink batch from pad 40 on May 9 at 2:54-6:54 a.m. EDT. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Axiom-4 spaceflight participant mission to the International Space Station from pad 39A on May 29 at 1:03 p.m. EDT. The first stage will land back at the Cape about eight minutes after launch. A Falcon 9 will launch the next GPS satellite for the U.S. Space Force from pad 40 on late May.

Florida Starlink launches continue though May with little competition for either LC-39A or SLC-40; the launch pace will be primarily determined by pad and ASDS turnarounds and the Space Coast weather during the launch windows.  (IDK enough about LC-39A Starship demolition/reconstruction to offer an opinion.)

This bundle of Starlinks may launch from LC-39A in the middle third of May, as there are currently Starlink launches scheduled from SLC-40 on May 7 and 9 UTC.  The May 4 Starlink 6-84 launch from LC-39A was successful.

Launch Mission Execution Forecast.

[Galactic Penguin SST]

Delayed to May 12:

https://www.spacex.com/launches/mission/?missionId=sl-6-83

SpaceX is targeting Monday, May 12 for a Falcon 9 launch of 28 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA�s Kennedy Space Center in Florida. Liftoff is targeted for 12:06 a.m. ET, with backup opportunities available until 3:57 a.m. ET. If needed, additional opportunities are also available on Monday, May 12 starting at 11:32 p.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 28th flight for the first stage booster supporting this mission, which previously launched CRS-22, Crew-3, Turksat 5B, Crew-4, CRS-25, Eutelsat HOTBIRD 13G, O3B mPOWER-A, PSN SATRIA, Telkomsat Merah Putih 2, Galileo L13, Koreasat-6A, and 16 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.

B1067-28!
