I hope I can say this much. Interesting news on L2 about this.
Let's hope Chris doesn't slap me for saying this little.

BTW, I have to say that it gives me a silly thrill to once again see in a launch discussion thread Launch Complex 39A. ;D

The TE seems to be sheathed with sheet metal in the video.  Is that new?

Verry nice!
Of course everyone wants something different.  I would have liked to see the center core land on the barge "Instructions".  Butif we wait until we see what SpaceX will really do we won't need these spectatular annimations, so this is a wonderful preview. 

edit: The grid fins droop after touchdown like F9R-Dev1!  Fantastic detailing.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

New, or the modeling/animation crew avoiding modeling the TE accurately. ;)

NERD CHILLS
Did y'all catch the braces retracting back into the center core after booster sep? (0:36s or so)

Edit: My bad. There's a stand-alone thread for the video:

Re.: The FH promo video: I wouldn't be surprised if, for the heaviest payloads, the central core landed on the barge in the mid-Atlantic somewhere.

Still, for average-sized payloads, the boosters and the main core should all make it back to KSC. Seeing them landing all in a neat row IRL will be quite the sight!

Re the FH video: Are there any concerns with sound waves bouncing off the fixed srevice structure, if it is enclosed and given its size, as the vehicle launches?  Would it be correct to assume enclosing it would be an attempt to lower maintenance costs by reducing the number of components exposed to the elements?

Is the Mid 2015 in the thread title new?

Nope, it's actually very old. I've changed the title to reflect what was reported one page back.  ;)

Thanks. That is what I meant. It is new in the title, not that the data is new.

There seems to be a "bump" about 1/3 of the way up on the boosters. I wonder if this has anything to with the cross-feed mechanism.

No, that exists on all F9s, although it is usually not very visible since it faces the erector at launch. (See image below) It is placed right around the common bulkhead, so it may be some kind of emergency tank vent.

Here's a JPL press release on the Deep Space Atomic Clock mission which is flying on STP-2. Only says it is flying in 2016 on Falcon Heavy.

According to Jeff Foust:
Gwynne Shotwell, SpaceX: expect first Falcon Heavy launch now late this year, three more to follow in subsequent 6 months. #satshow

Anybody care/dare to speculate on what this means?

Sounds like they're realigning the projected Falcon Heavy launch date to realign with reality.

However, 3 more Falcon Heavies within 6 months from that shows a big ramp-up production. That's a total of 12 boosters, and 112 Merlin engines and 48 legs and 48 fins. But many are likely to RTLS at least the boosters, which they've already shown they can pull off...

...which implies to me at least SOME components could be reused.

Attached is an ELaNa presentation giving a launch date of 1 March 2017 (under review) for STP 2. This flight is carrying three cubesats on ELaNa XV; ARMADILLO, LEO and StangSat.
