Thread for the Starlink 4-27 group launch.

NSF Threads for Starlink 4-27: Discussion

Successful launch August 19, 2022, at 19:21 UTC (3:21 pm EDT), from Canaveral SLC-40, on booster 1062-9. The first stage successfully landed aboard A Shortfall of Gravitas.

Payload 53 Starlink satellites to 53.2 degree inclination on a northeastern trajectory. Initial orbit is 232 x 336 km.

Starlink v1.5 satellite mass is now about 300kg after the addition of laser ISL terminals.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

Starlink 4-27, operations start NET August 9, northeastern trajectory:

Quote from: gongora on 07/08/2022 03:28 am

1174-EX-ST-2022
Mission 1789 Starlink Group 4-27 from Cape Canaveral FL at LC-40 CCAFS or LC-39a at KSC
ASDS North 32 40 49 West 75 40 25

Looking ahead, what first stage will Starlink 4-27 launch on?

Rotating forward the boosters available in Florida, by oldest available after previous recovery, but not already assigned, gives us: 1052.6 (May 18), 1060.14 (June 17), 1061.10 (June 19), 1073.3 (June 29), and possibly 1058.14 (July 7) and 1067.6 (July 15).

KPLO/Danuri, launching on August 2 UTC, is said will use a booster already recovered 5 times. 1067.6, if recovered successfully on July 15, likely will not be ready. That would make 1052.6 the first stage for Danuri.

Deducing from the "last use" rotation, 1060.14 will launch Starlink 4-27.

None of the available first stages would require a Static Fire.

Edit August 3: First stage is 1062.9--no need for a Static Fire. Previous launch/landing July 24 for Starlink 4-25.

1052.6 : KPLO
1061.10 : Starlink 3-3, after transported to Vandenberg
1073.3 : Starlink 4-26
1062.9 : Starlink 4-27
1067.6 : Starlink 4-23
1069.2 : Starlink 4-20

Edit August 19: Rollout late August 18. No Static Fire.

SFN Launch Schedule, updated July 21:
Mid August launch from SLC-40.

My thought: Starlink 4-27 may launch shortly after Starlink 4-26.

Perhaps instead, the launches of Starlinks 4-27, 4-23, and 3-3 will be grouped?

Starlink 4-27 launches after the mid-point of August. August 15-20?

The next Falcon 9 launch is scheduled for Friday from Vandenberg Space Force Base in California with another group of Starlink internet satellites heading one of the network’s polar orbit shells. That will be followed by another Falcon 9 launch for the Starlink network set for Aug. 16 from Cape Canaveral Space Force Station.

In reconciling the weekly list of active NGA notices for NAVAREA IV, I found that 794/22 (the NGA notice I posted above) was not listed as active.

Searching through my alternate set of notices, I found that 794/22 was canceled by 795/22:

2. CANCEL NAVAREA IV 698/22, 794/22.

That's totally bogus to cancel a notice as part of something completely unrelated. It's almost certainly a mistake, however 794/22 is in fact no longer active.

I would not assume that this means that there is any change to SpaceX's launch plan.
