No application for linear branching manifold arrays in starship, and probably not in superheavy either - will more likely be tree structures, so I am picking launch pad water deluge system
The glass is neither half full nor half empty, it's just twice as big as it needs to be.

Is Mk 2 a bit taller than Mk 1?

You made me want to compare them and... intriguing! Looks like Mk2's barrel section is already substantially taller than Mk1 if you account for the foot or two that will be cut off Mk2 to remove it from the concrete stand.

they will probably cut off half a ring from the bottom of each section like they did with mk1, so I'd say no.

my understanding is that mk1 and mk2 are different approaches to building the same design.

John's new picture on twitter:

https://twitter.com/John_Winkopp/status/1194288326800560128

on bottom right corner now we can see 2 raceway covers that transition to bottom fin aero covers, one of those new aero covers for the top fins (that were just installed on mk1) and one of the covers that will transition to the top end, which are yet to be installed on mk1 too.

edit: inside the nose cone there's a rectangular section, most likely the slot for the fin actuator piece.

gonna reupload so you can see in full res: credits John Winkopp / Seamore Holdings

Usually SpaceX does not spend time doing something without a reason.  Is it possible that the rings that have been done a long time but just laying around are actually some kind of welding or orther manufacturing process test to see how much it corrodes or if different processes corrode differently?   instead of "lets go ahead and put some rings together to get ahead?

Can't speak for SpaceX, but I wouldn't make dozens of rings 9m in diameter, weighing hundres of pounds just to see how a weld behaves.

It would appear that the reason Mk2 (tanks) section is currently taller than MK1 was that they added that last ring section to the top of Mk2 tanks instead of the bottom of the fairing as it is on Mk1.

Unpopular opinion... Compared to Texas Mk 1, Florida prototype Mk 2 just doesn't look like it has moved forward much in months. 

To paraphrase a young Fred Savage from The Princess Bride... "When does it get good?"

Are they ever going to put the domes in and fins on?

Agreed, but there appears to be some things likely in play here. First, preassembly seems to be getting tested in Florida such as many of the dome components, and possibly internal components before attaching the dome. They also may be looking to complete internal components first for EHS reasons as there is better internal airflow with the dome off. Preassembly may make final assembly very fast once it does occur.

Mk2 may also be waiting on testing results of Mk1, and there may be some engineering changes in progress for Mk2 already after learnings of MK1. The fact they have started work on MK4 for known components (rings) points to the fact there might be an engineering hold going on as well at times.

There is also the possibility that Mk2 may not fly if MK1 is successful and may go right to work on orbital versions. If that is true, MK4 could be assembled much more quickly since most of it's rings appear to be completed.

It's also possible that personnel from Florida may be in Texas assisting in getting MK1 ready for flight sooner. There are a lot of cranes in use in Texas, not unlike when they rushed to fit Starship for the presentation.

These are all possibles of course, and we have no facts here, but I'm sure SpaceX has their reasons, some of which I may have gotten above.

I believe itís all but confirmed that a large part of the Florida team is in Texas getting MK1 ready for flight.

It seems pretty logical to let MK1 testing inform / confirm MK 2 design decisions. Therefore itís unsurprising to see little work happening at Coco. Personally Iíd be more surprised if they were running full bore over there.

Also waiting for Raptors. Elon said they could be the crimp in the pipeline, so SpX trying to ramp up production.

I don't think they are in some kind of stand-by mode. In each video of John Winkopp you can see lots of cars, though I agree with you that they are waiting for some results from Texas regarding MK2. I wonder what that layout of the large factory building is. Is there a large workspace inside or mostly smaller "offices".

PS: There's a BBQ going on in the latest video from John Winkopp  8)  (bottom right, near the pool)

Looking at the manifolds and such, looks like they are also working on non-Starship components as well, possibly launch pad components.

We saw components like the control surfaces, raceway covers, mounting brackets, leg assemblies all being trucked into Boca Chica, could it be that all of these parts for both MK1 and MK2 are being built indoors at the Cocoa facility?

I knew the Fl crew was in Tx for the presentation but havenít heard one way or the other about them being down there now.


Boy Iíd like to hear some of those bar conversations. ďYíall donít know whacher doin. Itís all wrong.Ē
We are on the cusp of revolutionary access to space. One hallmark of a revolution is that there is a disjuncture through which projections do not work. The thread must be picked up anew and the tapestry of history woven with a fresh pattern.

Maybe there's a bit of a go-slow on the Florida build because there's nowhere for it go yet.

Boca Chica launch facilities are nearly finished....
Florida? Well, they've started pouring concrete and put up a couple of frames, most of the supporting infrastructure is yet to appear.

Wasn't there another location for assembly pictured recently among the trees somewhere?
What happened to that?

 A little further away than a drone,but  ;)
