Doug arrived in Charleston at "2024-01-19 07:47 LT (UTC -5)" and now in the same spot Bob had been, 1km downriver of JRTI - presumably for the same maintenance?

Bob left port at "2024-01-21 13:12 LT (UTC -5)" and heading to the Cape

JRTI still sitting in the same spot

If this is all running to a master plan, then Doug and JRTI both return to service mid-Feb for Starlink 6-40 or so?
After Starlink 6-38 (ASOG landing?) there are 3 back to back RTLS, which at least is consistent.

It was mentioned in the manifest discussion thread about OCISLY's turnaround record with Starlink 7-12.

This was not some photo-finish, it smashed the previous record by more than 2 whole days, and is even faster than the ground landing zones!
(though TBF that reflects how the ground landing zones are used, not their capability)

5 hours before that, ASOG also just hit a 6 month median turnaround time of 10 days exactly

Once JRTI finishes maintenance, I think we can expect them all to reliably turn around in under 10 days on average



Into the weeds:

Some kind stranger (I forget which forum member) maintains this database of booster and launchpad turnarounds. I piggyback off that and add in landing locations.

The new record for turnaround of any landing location is now:
OCISLY 5d-05h-22m set on 2024-01-29 with Starlink 7-12, B1075.9

The previous record was:
LZ-1  5d-18h-06m set on 2023-01-15 with USSF-67, B1065.2

The previous record for a drone ship was:
JRTI 7d-18h-50m set on 2023-06-12 with Starlink 5-11, B1073.9

The shortest previous turnaround by OCISLY, or any west coast drone ship:
OCISLY 8d-00h-37m on 2023-10-29 with Starlink 7-5, B1075.7


OCISLY isn't normally even close to competing for multiple turnarounds in a short time, but now it snatched the records for 2 and 3 successive turnarounds:

→ 2 turnarounds in 14.87 days, under 20 days for the first time for OCISLY (prev 20 days and 4 mins in 2021), but the 14th time for any drone ship (first in Aug 2022)
Previous record:
JRTI 16.11 days on 2023-06-12 with Starlink 5-11, B1073.9

- 3 turnarounds in 26.09 days, under 30 days for the first time for the west coast (prev 33.68), but the 10th time for any drone ship (first in June 2023)
Previous record:
JRTI 27.46 days on 2023-06-23 with Starlink 5-11, B1069.8

A look at medians of the last 30 turnarounds: (FWIW very similar to the means)
- JRTI: 11d-21h-32m - unchanged since a new record on Nov 28
- ASOG: 12d-05h-06m - unchanged since a new record on Jan 15
- OCISLY: 14d-03h-14m - A new record since Jan 29

For reference, a year ago JRTI and OCISLY were about 18 days. ASOG had just over 15 days (median of all 25 turnarounds)

ASOG has had a good run especially since August - 17 turnarounds in 185 days
Median of just the last 17 turnarounds: 10 days exactly. (mean: 10d-21h-00m)
JRTI was almost that good back before the mid-December weather delays and now maintenance.
(median 10d-01h-43m, mean 10d-18h-42m)

It's called Marmac 303, have a look

JRTI is now out of the dry dock, and on "Pier G"

Well, at least I presume that place is a dry dock. Anyway, it moved.

Nope. Doug and JRTI are heading out to sea again already

Just Read the Instructions droneship has wrapped a month-long visit to a shipyard and is heading home to Florida. Doug is towing.

Just Read the Instructions droneship is back home in Florida and sporting a fresh coat of black paint all over. So much better than years of hard-earned battle scars from salt water.😍

The other visual change I've spotted includes the removal of the 'candy cane'  exhausts from each thruster unit.

JRTI left for the shipyard with a generator set and a container on the landing deck, which I assume have been installed deep into surrounding GSE at the bow and stern.

The 'candy cane' exhausts (at least this is what I've always assumed they were...) for anyone who thinks that I've got crazy.

Maybe they're intakes (engines or ventilation)?  And the candy cane is a splash guard?  Don't know for sure just guessing.

You're talking about the tubes Olive Oyle always screamed from, right?

EDIT: oh never mind, on my phone  didn't see the picture, her head would not fit in those.

While looking for info about Blue Origin's ASDS, I noticed this:

This may be completely irrelevant, but we've got a just completed 300' barge operated by McDonough Marine Service (who SpaceX charters their other 3 barges from), in the same basin as "Of Course I Still Love You SpaceX". It seems to be heading to Hawaii, where the Starship EA report makes multiple references to a potential landing barge:

Quote
Full reusability entails Starship and Super Heavy landing back at the launch site or on an ocean-going barge or floating platform, which would then be towed back to port.

Is this SpaceX related?

This may interest you as well, this post the several beyond it.

China is developing reusable rockets to launch in 2025 and 2026. See the 'net' technology they will use to catch the booster when it returns to Earth in this animation.

Hmmm a naked barge without mods?

Well, if it IS for SpaceX and IS destined for Hawaii operations, it would make a lot more sense to tow it empty to Pearl for fitting-out there rather than load it up on the mainland and drag it across the Pacific (which can be anything but) 
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Now Im not saying this means what we all hope it means, but . . .
