Nothing confirmed yet, but this launch could be delayed.  Finn Falgout just left port again, heading "Offshore to rescue the Hawk" per marine VHF.

Tug Finn Falgout has just departed Port Canaveral - amid reports via maritime radio - that tug Hawk, currently towing JRTI droneship to the Starlink LZ, has suffered a mechanical fault and needs rescue.

Support ship GO Quest has also departed - which may linked to that effort.

Quick update on this: First thing this morning Just Read the Instructions was handed over from Tug Hawk to Tug Finn Falgout, with the help of support ship GO Quest.

The fleet is now en-route to the Starlink LZ. I'm not convinced they'll make it in time for T-0 but we'll see...

SpaceX is targeting Wednesday, April 28 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 11:44 p.m. EDT, or 3:44 UTC on Thursday, April 29.

The Falcon 9 first stage rocket booster supporting this mission previously supported launch of GPS III Space Vehicle 03, Turksat 5A, and four Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be located in the Atlantic Ocean.

I was close when I heard about the one-day slip.

I assumed it would be 22 minutes earlier than the original launch time (04:05 UTC), so that would’ve put the launch time at 03:43 UTC.

I was close when I heard about the one-day slip.

I assumed it would be 22 minutes earlier than the original launch time (04:05 UTC), so that would’ve put the launch time at 03:43 UTC.

It's slightly over 21.5 minutes earlier each day, so with times that only go to the minute it alternates between 21 minutes earlier and 22 minutes earlier, except that occasionally it is 22 minutes earlier two days in row.  Here are my estimated launch times.

Primary Day = Thursday, April 29 at 03:44 UTC.  21 minutes earlier than 04:05.
Backup Day #1 = Friday, April 30 at ~03:22 UTC.  22 minutes earlier.
Backup Day #2 = Saturday, May 1 at ~03:01 UTC.  21 minutes earlier.
Backup Day #3 = Sunday, May 2 at ~02:39 UTC.  22 minutes earlier.
Backup Day #4 = Monday, May 3 at ~02:18 UTC.  21 minutes earlier.
Backup Day #5 = Tuesday, May 4 at ~01:56 UTC.  22 minutes earlier.
Backup Day #6 = Wednesday, May 5 at ~01:34 UTC.  22 minutes earlier again.

Edit: Fixed a missing word typo.
