For a January 7 launch from VAFB, when would we expect JRTI to leave port?
Do we have anyone checking on it on a regular basis?  Is it visible on any webcams?

edit:  Do we expect SpaceX to use JTRI, or do we think they will attempt RTLS?  Have we seen a completed landing pad with the big X on it?  Are we still waiting to hear of Air Force approval as Jim suggested in the "SpaceX VAFB landing facilities" thread?

Marine Traffic tracking of the tug.

What's the name of the west coast tug?

Titan IVB was a cool rocket

I thought American Islander was the Dragon recovery ship, but I guess it has a second purpose.

In case of Jason-3 flight it was International Freedom.

Since SpaceX hasn't landed a stage launched from VAFB, where will they offload, safe the stage? Do they have the same stand [with deep pad anchoring], cranes and GSE that they process the S1 for Transport? Do we have members that can document the offloading procedures? Thanks in advance ;D

Didn't they build a stand over on the dock where they moor the ASDS?

IDK: i haven't seen any pictures in a while. They have offloaded stage fragments, but never safed/disassembled one in Cali.

It looks to me like American Islander lit up her vessel tracking equipment a few hours ago, albeit just briefly. I believe it had been "dark" for several days prior.

Which is currently in Hawaii.

NRC Quest is about 15 miles off of the coast and headed southwest, following behind the tug Pacific Warrior.

PACIFIC WARRIOR may just be the tug pulling JRTI out...  8)

Will have to keep an eye on that one...  :)

Anyone have the JTRI location from the Jason-3 mission for comparison? Seems about the right place for an offshore F9 recovery, roughly 300 miles south of VAFB.

Quoting from way back, with a link to a map with various bits on it, some possibly relevant:

Here's a link to the map made by darga showing the barge location for Jason-3 as specified on the FCC transmitter permit.

It appears to be positioned to allow a booostback just west of the Channel Islands, getting as close to the islands as possible without overflying them.

Looks to me as if it's a reasonable vicinity, more or less.

I wouldn't think NRC Quest is heading out for the launch yet. The Quest ships cruise in the 12 knot range whereas a tug towing an ASDS is more in the 2-5 knot range and usually depart ahead of the support ships. NRC Quest it likely just shaking off the cobwebs...

DroneShip target position is 96km southwards from last Jason-3 landing position. 342km from the port and 372km from launch pad.

From actual position of Pacific Warrior it is approx. 220km. By speed of 6 knot it could take about 20 hours.

I can't seem to reconcile the FCC license location with the stated destination of Pacific Warrior: "100NM S CORTEZ BNK."

Cortes Bank is roughly 119.2 degrees west; the FCC location is 120.5 degrees west.

EDIT:
Wikipedia says Cortes Bank is 32 28 41N, 119 12 54W. 100 NM is 185.2 km. So the stated destination of Pacific Warrior is 30 48 46N, 119 12 54W.

That's 134.8 km from the FCC location of  31 17 45N, 120 30 46W.

31 17 45N, 120 30 46W is 97 nautical miles from 32 28 41N, 119 12 54W in a south/southwest-ish direction. I think you're inferring too much precision from the stated destination, particularly the direction.
