They are still in port.
That's potentially sad news, splashing a new one, rather than a block 3...

If true though, while sad, it is the right thing to do for the customer

KoreaSat-5A is only 3500 kg, a Block 4 F9 can easily send that to supersync GTO with a barge landing. Why wouldn't they try to get it back?

They still have some time left AFAIK, might be rushing to finish up repairs

If they do a partial boost-back burn to return near the coast, the droneship won't take too much time to get positioned.

Nod. I wonder how much time they need to reconfigure things or if they have already calculated 5 or 10 different parameter loads for different landing points or even expendable with different things tested or ?

They've used a "contingency landing location" that repositioned the ASDS on at least 1 previous occasion, IIRC it was on one of the Iridium launches.  Which tells me that they likely have at least 2 or 3 targeted locations set up well before hand.

Taken by VIP-badged guests at KSC earlier today! No obvious TEL changes that I can see.

Looks like the wings at the top of the TEL have been removed.

I see them wrapped around the top of the rocket.

No - those are the stabilizer arms.

But I do think the wings are still there, just very hard to make out

They are still in port.

As far as it appears:

Hawk with OCISLY left Port Canaveral on Friday morning and was last noted far enough offshore to be pretty much confirmed as heading to the landing area.

Go Quest left port on Saturday.

Go Searcher is in Puerto Rico, but they only need one ship to back up OSCILY (per west coast practice).

Unless Iím mistaken, everything is in place for an ASDS recovery.

It does not.

When will they post the webcast?  The launch is supposed to be tomorrow.  They seem to be getting later and later on posting.

I'm guessing about 12 hours before launch is when SpaceX will post the webcast.

Technically, it's when they begin promoting the upcoming webcast.

Normally SpaceX don't update the webcast page on their website until after the vehicle is vertical on the pad, as they like use a photo showing the pad with the vehicle in launch position on their frontpage.

Well, they have the webcast link up, and its showing "live at 3:34am gmt-7" (6 hours from now)
So I'm guessing someone needs to update his pc's clock, or remember what timezone he is in, as this does not agree with the previous Notams, etc, issued for this launch.

I'm assuming that whoever posted it accidentally put "7:34 UTC" without specifying PM (since the listed time is 12 hours before the actual time), and that the actual launch time hasn't changed.

Edit: Changed from 10 to 7 UTC, my mistake - I myself have trouble with time zones sometimes.

Per SpaceX's website:

Quote
The primary launch window opens on Monday, October 30 at 3:34 p.m. EDT, or 19:34 UTC and closes at 5:58 p.m. EDT, or 21:58 UTC.

A backup launch window opens on Tuesday, October 31 at 3:34 p.m. EDT, or 19:34 UTC and closes at 5:58 p.m. EDT, or 21:58 UTC

10:34 / 22:34 it certainly ain't!

Could be a typing error for 19:34 UCT substituting a 0 for the 9 (they are side-by-side on a laptop keyboards) ?

In the SpaceX photos on the updates thread there is a band around the left landing leg but not around the right one.  Why the difference between legs?
