It appears that thread about our beloved ship (or ships more correctly) silently died  :(

Any updates folks? Pictures?

I too have so little time to continue with my OCLSLY model, but hope to resume it tomorrow.

The thread hasn't died.. it's only sleeping.

Jokes aside, there's been no action on the ASDS front 'cause one is away getting it's bottom scrubbed and the other is parked securely berthed awaiting another opportunity to catch something.  Be patient, they'll be out on the high seas again soon. :)
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.

Did I miss something? OCISLY got back from drydock over two weeks ago.

Don't know if anyone else mentioned this but Marmac 303 had some replacement work done that is now listed on USCG website

This says that the due date for the repair of the "Electrical Supply System" is Aug 1. 
Should be plenty of time for JCSat-16 launch, even if we don't have an exact launch date for it.

Let's not mix up our ASDSs.  That report seems to have been for the west-coast one, JRTI, as the USCG base was San Pedro, California.

Oops.   :-[
I missed the San Pedro detail.
Then there's even more time margin to the Iridium launch NET Sept 12.
Just in case...

My HVAC part came in and the same technician came out, so I have a followup report based on the questions that came up here. In fact, he gave me so much information this time, it might be better if I just bullet most of it. In addition, he said he took some pictures while his team was working and he will try to find and post them here.

⦁   the 2 containers have only 2 air handlers each, which hang from the ceilings inside, and each air handler is shared by 2 outside condensers
⦁   previous estimate of 4 tons per condenser modified to 4 tons per air handler, for a total of 8 tons of cooling per container
⦁   the 4 A/C condensers outside each container run 2 at a time
⦁   the interior temperature is kept at 68 degrees
⦁   SpaceX freaked out when the repair team had the temp turned down to 60 degrees to test the system

***what's inside the box***

⦁   mostly telemetry servers to communicate only with the support ships, possibly also with the rocket
⦁   communication w/ Hawthorne ruled out as too far, relayed through support ships
⦁   GPS system with more precision than comes standard with the thrusters
⦁   video telemetry servers
⦁   desk
⦁   monitors

There's a new place to hang out and watch OCISLY come in if between 7am & 7pm, a new Fishlips location with ocean views at Jetty Park

Sorry.. I haven't been watching too closely.  I've have paid work to do..  :-[

I've had another look at the latest and it does seem OCISLY was inspected on 22nd June with final USCG sign-off on the 27th.  No issues found and, assuming she doesn't get into trouble, she'll be left alone until 2018 at least.

One point of interest for both our ASDSs is a change in USCG classification from "Research Vessel" to "Industrial Vessel" ...but of course, as far as ABS are concerned, they're still barges.

How times have changed.  Only a couple of launches ago we would have been estimating departure times and sending out stalkers ahead of time.  Now it's just an footnote...

I think the interest level will rack up when they have to send out two barges for Falcon heavy, bring it on !

We have it from multiple sources (Elon, Gwynne, and the notice of EAS amendment) FH will land boosters back at LZ-1.
Space is not Highlander.  There can, and will, be more than one.

I would guess that would depend on how high performance the launch would be, but I agree most launches would be in the return to launch site thinking  about it, it's going to be unproductive to have 3 barges out at sea, not worth the cost.
So I have to admit a bit of a dumb post this time.

Considering the issues SpaceX has had with the sat uplink on the barge dropping out during landing due to vibration (speculation on my part) I wonder if they would do better to use an omni-directional VHF link to the support ship and then do the sat connection from there.  Also, not having sat uplink on the barge itself would cut down on the cost and complexity of equipment that has to be so close to the business end of a running rocket.

rightly so.  The point is to put payloads into orbit and not to land on barges

Where does it say sat uplink in that list?

SpaceX thinks their mission is "To enable the space flight capabilities necessary to make human life multiplanetary - or more specifically enable a self sustaining human civilization on Mars."

(From here: https://www.quora.com/What-is-SpaceXs-mission-statement)

Curiously, SpaceX agrees:

"The company was founded in 2002 to revolutionize space technology, with the ultimate goal of enabling people to live on other planets."
