SpaceX F9 : Starlink v1.0 L14 : CCAFS SLC-40: Oct 24, 2020 (15:31 UTC)

They have obviously lost a feed from the camera, and with no means to check if it has mechanically lost, cable loose, or just a failure within the unit, they decided to scrub.

Just a small-seeming issue with loss of upper stage camera. Probably nothing serious, but standing down to re-examine whole vehicle just in case.

Presumably, if it's a networked camera, they would want to exercise any or all other sensors that might be on that subnet if any.

New hazard area indicates SpaceX is now targeting no earlier than 10/24 @ ~1130 ET for next attempt at 15th Starlink mission.

They have obviously lost a feed from the camera, and with no means to check if it has mechanically lost, cable loose, or just a failure within the unit, they decided to scrub.

Nobody wants either of the cameras aimed at the MVac to be flopping about near the sensitive bits during ascent, nor the payload cam. Or their cables. Or if it's a data multiplexing issue, what other telemetry might they lose at a critical time?

I concur, especially in the context of the engine trouble with B1062.

An abundance of caution coincides with risk management in this case.

Also gives a couple of additional days for repairs to the fairing catchers.

Space Force official: Launch scrubs are no reason to despair

A streak of United Launch Alliance and SpaceX launch scrubs has frustrated rocket company executives and space aficionados. But Space Force launch managers are not discouraged, and in fact see scrubs as proof that systems are working like they should, Col. Douglas Pentecost said Oct. 22.

Or one of the internal cams.  Certainly don't want the LOX tank cam flopping about.

L-2 launch weather forecast (issued yesterday for launch tomorrow) is 60% GO

[scr00chy]

Exact launch time is October 24 at 11:31am EDT, according to Ben Cooper.

That’s the time given by SFN.

  Navigator and GO Searcher are being deployed for fairing recovery, replacing Ms. Tree and Ms. Chief for the Starlink mission.

Both ships are leaving right now but won't be able to get into position in time for launch tomorrow... which suggests a few days delay to Starlink.

Dragon recovery equipment was removed from the two ships earlier today and the equipment for fairing recovery installed. The ships will able to haul the fairing from the water.

Photo earlier today via @NASASpaceflight fleetcam of the fairing recovery inflatables being installed.

[Jansen]

18 hours isn’t enough time to deploy to fairing landing area? Thought they only needed 8 hours travel time.

That only applies to Chief/Tree coming from Morehead City. Searcher/Navigator are slower and coming from Port Canaveral which is further away.

It looks like economical cruising speed is around 20km/h, so it would take 36 hours to get 725km downrange. I can't find anything about top speed though.

A valid deduction.

However, might Navigator and GO Searcher retrieve the PLF halves from the water hours or a day after they splash down?  How long do fairing pieces float?  What is the sea state in the PLF recovery zone?

(God to Noah, via Bill Cosby: "How long can you tread water?")

EDIT: Well, I was partially correct. No one (?) considered SpaceX chartering another boat to babysit the floating PLF halves until one of the specialized SpaceX fleet can arrive on-scene, until later.

That's probably close to top speed for that thing.

[cpushack]

I wonder how far they can 'fly' the fairings closer?  If they can use the steerable chutes to get closer they can make up for some of the gap

[Ken the Bin]

L-1 weather forecast for today and tomorrow: 60% 'Go' for today, 50% 'Go' for tomorrow.  The forecast says that it was produced yesterday at 12:00 UTC but I can tell you with certainty that it was wasn't posted publicly until after 04:00 today.
