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.

BTW, Kabloona, I don't suppose your bird friend would be willing to take a camera on future overhead flights?

You may have missed earlier where I said it can't carry anything because it's a European swallow. Now, if it were and African swallow, it might be able to carry a camera...but sadly it isn't.

Oh, well, I was wrong.  I figured that it made more sense to use a west-coast barge.  Good job, NASASpaceFlight Intelligence Directorate - Central America Subdivision!

So.. if we know where Marmac 303 and '304 are, where has the Marmac 300 (a.k.a. JRtI) got to?!?

It's still the only USCG-approved ASDS in the SXN (SpaceX Navy)..

We don't know for certain, but rumor is that it is being reconverted back to a barge. and Marmac 304 is likely to take the name. Brain transplant, if you will.

Carnival Fascination is meeting the pilot boat for entry to JAX... looks like it's going to be a busy day for us ASDS stalkers; TWO ASDSs on cam!

Hrmmm.. we manage to track the ASDS ships on AIS due to knowing the ID of the accompanying tug. This may be much harder to do with Marmac 300 if it's no longer part of an ASDS; it's not as likely to have a dedicated tug in attendance.

Has anybody checked the ships passing through the Panama Canal for webcams?

Hello JRTI, no more container in the middle of the deck landing pad?



Edit: Ok. Container still on the landing pad

CruiseCam is here

For latest image

EDIT:

At bow both old thrusters remain.

Edit2: In fact muffler is installed atop on HPU at left.  And wall being worked upon deck (18,19)

I think HPUs muffelers at bow are within a cage.
No flag today. May be they do it at specific time of day singing SpaceX anthem ;)

Looks like they are doing something to the surface of the deck no?

I think it is one of side walls. There is new framework visible at sides at stern just like at bow.

Edit:Uh huh right in front ofcontainer :) It has door on it too..

Yup. Agree. But the surface seems to have 2 different textures, like if they are adding  a new layer or something like that. I don't remember seeing 2 different textures/colors at the surface of the deck.

304 does show stripes under right circumstances. You can check on 6 June video. Oooh SpaceX flag is there just a bit less enthusiastic :)

So.. if we know where Marmac 303 and '304 are, where has the Marmac 300 (a.k.a. JRtI) got to?!?

Word is that Marmac 300 will soon be carrying components for a large wind turbine project. One possible assignment *might* be carrying the giant foundation pieces from Houma, Louisiana for Rhode Island's Deepwater Block Island (Rhode Island) wind farm (M300's possible association with this project is only my own speculation but it fits with some details I've overheard. The location and timing also make sense since M300 is in Morgan City which is next door to Houma, and the foundation pieces will be ready to ship at the end of this month.)

http://m.providencejournal.com/article/20150613/NEWS/150619923

Another possible assignment for M300 *might* be carrying the wind turbine blades for that project, wich are 73.5-meter blades being built by LM Wind Power. Not certain which facility is building the blades, but LM Wind Power does have a plant in Little Rock, Arkansas, just up the Mississippi from Morgan City.

No.  Mostly, I think.  The former Marmac 300 based ASDS always had longitudinal stirpes in the morning unless it was raining and (going back and reviewing pictures just now) even sometimes when it rained.  Most of the time those stripes disappeared at ~10am.  Due I postulated at the time and now seems near confirmed to the formation of dew on the deck in response to what's under the deck and its thermal mass.  Under the deck of the Marmac 300s are four rows of ballast tanks and they keep the outer two rows ballasted for towing and deck water spraying during the actual landing (this last part just recently confirmed).  In addition to the differences under the deck caused by the fill level or non-fill condition of the ballast tanks you've got the deck extensions which have air under them and are possibly of different thickness and probably have less paint thickness.  The recent images of the Marmac 304 based ASDS show longitudinal striping that isn't as well defined (lines waver) but I think some of what's behind it is the same.

Rhea in same place still.

Capt. Latham has not yet emerged from the deep ocean LOS but would seem to be on what is for it a routine trip to San Juan, with arrival approximately tomorrow or so.

Go Searcher, Go Pursuit, Go America - No recent position information (last night).

Marmac 300 - Google had no news as of last night but Kabloona does so there ya go.
