It's awesome 👌 being such a mover and a shaker!

I feel like Bob Uecker: "I must be in the front row!"

L-1 Weather Forecast: 95% GO

[Galactic Penguin SST]

And I spoke too soon, it’s been scrubbed for the day.

SpaceX is targeting Tuesday, February 4 for a Falcon 9 launch of 21 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 3:37 a.m. ET, with backup opportunities available until 6:24 a.m. ET. If needed, additional launch opportunities are also available Wednesday, February 5 starting at 2:59 a.m. ET.

[zubenelgenubi]

Both Starlink 12-3 and WorldView Legion Flight 3 launches delayed from February 3 to 4.  The weather forecast today is nearly perfect.

Wondering why?  Launch vehicle processing delays?

Edit/add:

The delay for Legion 5/6 is apparently due to an investigation SpaceX is conducting related to a problem with the reentry burn on Saturday's Starlink launch from Vandenburg.

In theory there should be a T-20 minute vent here, but we can not confirm thanks to fog.

SpaceX has not confirmed prop load yet.
