SpaceX F9 : Starlink v1.0 L15 : CC SLC-40 : Nov 24 2020 (Nov 25 0213 UTC)

[Vettedrmr]

There were a couple Starlinks that did NOT static fire at all and went straight to launch.

But not a life-leader; all those have SF'd prior to launch.  OTOH, this *is* SpaceX!

Shortly after uploading yesterday forecast, 45th have now released L-2 forecast, which is now 70% GO

Apologies if this has been asked and answered (and I missed it), but any word on a static fire?  From the SpaceX manifest updates page, it appears that this will be the 7th flight of booster 1049.

No word yet, and nothing has been spotted.

I would be astonished if they don't slip.  The other SpaceX launch, scheduled for the same day, static fired two days ago.  What's the least amount of time they've done between the static test and launch?

I think a couple of Starlink missions static fired just 1 day before launch.

There were a couple Starlinks that did NOT static fire at all and went straight to launch.

Any idea what determines whether they do or not?

[Vettedrmr]

Seems to be if they have history with other 1st stages flying at least as many flights as the booster in question.  But there could be other factors we/I haven't read about.

Have a good one,
Mike

What's the least amount of time they've done between the static test and launch?

Shortest Time Between Static Fire and Launch (without Payload Attached):
73 hours (Nusantara Satu)

Shortest Time Between Two Different Static Fires:
15h 30m (Starlink v1-9 / GPSIII-SV03)

Thanks, that's good to know.  I'd been under the impression that if it hadn't happened three to four days ahead of time it wasn't going to happen.

A tale of two missions, Fleet style.
As GO Ms. Tree departs for Starlink, JRTI is being led in by Finn Falgout with B1061.1 on-board. This windy day is creating a rough sea state that just may be the reason for the lean we are seeing.

Friendly reminder:
We have a thread for Falcon 9 Static Fires: running tally of news and updates plus discussion. This helps keep the individual launch threads signal/not-signal ratio high.
SpaceX General Section subforum: SpaceX Falcon 9: To Statc Fire or not to Static Fire: that is the question.

#SpaceX has a 🚀 vertical on LC-40 for Saturday nights Starlink launch.

Up this early (+48 hours before launch) means probable static fire very soon.

Looks like the static fire may have been aborted. We did not see any action at 1:30 a.m. Eastern as expected.

Looks like the static fire may have been aborted. We did not see any action at 1:30 a.m. Eastern as expected.

Was any activity noticed prior?  Example: big vent at T-20 minutes.
EDIT: Re-playing the coverage, there is venting visible when the camera is turned towards the pad at 1:16 am EST.
Big vent as the clock turns from 1:26 to 1:27 am EST.
Another big vent as the clock turns from 1:28 to 1:29 am EST.
Prolonged vent through 1:29 and into 1:30 pm EST.

What is/are the source(s) for the expected time of Static Fire?

[Jansen]

Latest weather forecast still 70% GO

#Spacex #Falcon9  for 16th #starlink  launch still raised at pad 40 with nose cone this afternoon - after aborted static fire overnight . New test /launch target TBD

[Vettedrmr]

Do we know if it was in fact an aborted SF, or could SpaceX be going to a WDR approach?

Several websites with SpaceX contacts were given a 1:30am time for static fire.

Just surprised that an assumed SF abort would be met with apparently zero response.  I understand we're looking from a distance, but everything just seems to be moseying on like everything is happy.

No one is panicking because it currently appears to be a minor issue. No delay announced, and everything is still vertical which indicates they will try again.

Appears to have slipped 1 day:
