The time track on her way to LA from Florida:
Dec 22, 2017, 00:04 UTC LOS ANGELES, USA
Dec 03, 2017, 03:00 UTC MANZANILLO, MEXICO
Nov 28, 2017, 06:00 UTC BALBOA, PANAMA

So it takes around a month to get only to Panama.

Also on www.vesselfinder.com destination is SAN PEDRO CALI (actually it's the same destination on the marinetraffic site too if you just hover the pointer on the ship).

May be this is just a trial run?

Not really on-topic at this point, but it does not take a month for that ship to get from LA to Panama.  JRTI got towed from the Atlantic side of the Panama Canal to Long Beach in a month.  Mr. Stephen can move a lot faster.

Looks like another test! Mr. Steven is heading out for the second time in less than 24 hours.

And no, it's not going to Belize.  ;D

Worth crossposting here.  Click through to quoted post to see graphics:

INTERESTING!

SpaceX recovery support ships Go Quest and Go Searcher have left Port Canaveral.

Possible fairing recovery test!

Do we know approximate weight of the fairing half? I only found some data on spaceflight101 and do not know how accurate is their value of 1.75 t (per half ?)

From the transcript of Elon’s pre-FH demo launch press conference:

Quote
We are in the process of recovering the fairing, we're getting better and better at recovering the fairing. So we expect to recover the fairing and the booster, the first stage of Falcon 9.

For context, I'm pretty sure he was talking about "long term". That is, he expects the fairing recovery method they are developing to be ultimately successful.  There wasn't (in my listening) any implication that a specific upcoming attempt was likely to be successful---or not successful! No specific mission was being referenced is what I'm saying.

Cropped/enhanced portion of recent Elon Tweet with Falcon Heavy flight profile graphic.  Looks like a Mr. Steven-a-like rigs with nets (on Go Quest & Go Searcher?) will be on station.  The graphic doesn't show parachutes or two boats, but that's probably for simplicity's sake.

This is a graph made by a NSF L2 member. Even though reposted by Elon, it means it's not necessarily 100% accurate.
Although this is probably a pretty accurate timeline of what they want a standard FH launch to look like, it's possible that some of these events won't happen during this launch.

I have no certainty about the fairing recovery and the payload separation events, in particular. These may not be planned to happen during this launch.

In particular, Go Searcher is currently sitting at the dock across from Fishlips in Port Canaveral, so is not likely to be going out fishing for fairings today.

- the post-launch conference for FH - talks about Fairing recovery also. 55:50

Lightly edited to remove stumbles.

I'm pretty sure we'll have fairing recovery in the next six months.
It turns out that you pop the chute on the fairing and you've got this giant awkward thing it tends to interfere with the air flow on the on the parachute and and miss.

Gets all twisty and and was low priority too. But we have fairing version two which is the really  important one that we want to recover, so even if we recovered fairing version one, we wouldn't be re-flying it in the future. Fairing two and recovery that's very important, and my guess is - next six months we figure out recovery.
We've got a special boat to catch the fairing, like a catcher's mitt. It's like a giant catchers mitt in boat form.
 It's gonna run around it can't catch the fairing.
Kinda fun.
I think you might be able to do the same thing with dragon so if NASA wants us to, we could try to catch dragon.
Made for the fairing, but it would work for dragon too.

Do you have any more info about fairing version 2?
It will be part of block V?
Is it supposed to be more expensive to require recovery be "very important"?
Lighter?
Bigger?

The available info seems to imply it may go along with block V.
The bits of F9 that the fairing attaches to are more-or-less static and unchanged over all blocks, as I understand it.
It may well be more expensive, it's certainly newer. Lighter - well - possibly not - recovery hardware isn't air.

I don't think we've seen any reasonable speculation it would be bigger, and Elon did not mention this when he has mentioned much smaller differences in the above conference.

If the fairing is double the price, and you recover and refly nearly all of them, that's a real bargain.

Would a new fairing require requalification for EELV work?

About fairing version 2, SpaceNews has a hint here:
“One of the limits of the Falcon 9 for the DoD missions was that they needed a longer fairing. The payload was too tall for the existing fairing,” he said. “I’m hoping Elon Musk has a longer fairing on the Falcon Heavy.”

Sorry if I missed this, but are they going to try to use one ship to try to catch two fairing halves?  That seems even more improbable!

It is not impossible.
However, it's also rather likely that they're simply waiting to see how recovery works, before seeing if they need another identical boat, or a bigger/faster boat, or ...

Boats and steel and ropes and nets are cheap.
Especially so when you can resell them for a large fraction of the purchase price.

Compared to payload fairings yes they are.

I'd like to see the ASDS replaced with a custom built ship that is self propelled.  It should be able to return boosters to land faster than barges and tugs.   (Ideally a ship that could recover 1, stow it and recover another a day or two later.)

Catcher mitt style fairing recovery could be a very fast way to return them to shore.  Catch it, secure it and full throttle for port.  Hopefully they'll be able to get them protected from the elements after recovery.
SpaceX, just a few things planned for 2018: FH, Starlink Prototypes, Block 5, Dragon 2, Increased launch rate.

Under consideration. We’ve already stretched the upper stage once. Easiest part of the rocket to change. Fairing 2, flying soon, also has a slightly larger diameter. Could make fairing much longer if need be & will if BFR takes longer than expected.

with wider fairing he wont have to tilt the next car.  :)
With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.
