Really cool.  Probably dumb question... Do we know if this is the half that was recovered?
That's probably a safe assumption.  It's also probably a safe assumption that SpaceX has the complete video footage that this frame was taken from.

My assumption also.  The instant I saw the image I started looking for hardware that might have been used for recovery.  Not seeing anything obvious I started wondering enough to ask the question.  I do realize that the obvious stuff is probably up near the nose of the fairing and out of sight of the camera.

Here is a comparison showing the SES 10 fairing (inset) and a frame from the video SpaceX released a while back.
Some small differences but I have no idea if they are mission specific or related to recovery.
A small amount of knowledge can be a dangerous thing.

I don't know but since they can't broadcast from a fairing half and we know from past recoveries that SpaceX mounts GoPros in fairings, this must be from the recovered half.

Cute!

Can someone enlighten us what we see? My guess: 3 light tubes in the middle carry compressed gas/liquid to 2 pushers (sticking up from the edges), while black wires carry current to electric latches.

The batteries and gas tank should be at the fairing tip... together with recovery hardware.

Or may be those 3 light "tubes" are actually the paraglider strings attached to fairing aft?

Yes that seems about right. That would put them behind the camera.

You expect rockets to be quite crammed with equipment but the fairing looks very "clean," with no obvious lumps of hardware bolted on in shot.

That said with the flight path well defined it seems likely you could get away with GPS and some attitude sensors for the fairing to work out when to open 'chutes. While they separate around booster MECO so are a long way from orbit it would still seem like a good idea to keep the weight down.

I was ready to fire off a similar post (saying it had to be from the recovered half) when I remembered that vid (that the comparision still came from). Wasn't that transmitted from an unrecovered fairing? If so we can't be sure this still is from the recovered half.

(if it isn't then it's possible not all the equipment is present on this half making our sleuthing harder, LOL)

IIRC the previous video came from an "unrecovered" fairing that happened to wash up on a beach with camera housing intact.

It's feasible that the Go-Pros are mounted in pods that allow them a decent chance of survival. I mean, I know the standard Go-Pro is pretty tough, but not that tough.

Go-Pro definitely rides down with the fairing.  Good images of the "beached" fairing and Go-Pro here:  http://www.collectspace.com/ubb/Forum14/HTML/001305.html

Precisely
And we did see the protective case for the GoPro in the posts linked above.
The real-time fairing and payload separation videos are broadcast from the second stage.

In the center green box (the one right across from SES 10) looks like what could possibly be a mortar for the drogue chute in the center. The smaller package could then be the drogue chute with the larger package the parafoil. There appear to be some kind lines from that center box to the 2 boxes that you have marked at the back of the fairing. Could these possibly be the control risers and the motors? The center box leading toward the nose of the fairing that you have marked could possibly be for the risers to the front of the fairing. This would lead toward the nose of the fairing past the center of balance point. At which point they would have to branch off to the 2 sides for attachment points there. The 2 boxes you have marked toward the front could be these 2 attachment points. Alternately the 2 boxes in the front could be the control motors in the 2 to the back could just be the aft attachment points.

By scaling off a few public images, and noting the relative position of the eyelets, here is an estimated lateral view of the new items in the fairing. Of course, there may be more items in the nose.

I received a message from a source this morning that one-half of the NROL-76 fairing parachuted into the ocean was was recovered intact.
No other details yet.

One more tidbit just came through. Accuracy was about 4 miles from target.

4 miles is far too much for a bouncy castle... would it be close enough for an air recovery? Perhaps fixed-wing?

Or refine the parafoil's software.

Obvs.

The first fiew landing attempts were misses too. Just not the same kind of miss. But different variables
