1) I don't see any thrustmaster damage? Where are you looking?

I may be wrong but hydaulic lines seem to be damaged.

A damaged hydraulic line would prevent it being raised. Shrapnel damage, most likely. Should be an easy fix.



I wonder if the survival of the top of the stage is a result of a hard landing, i.e. the lower part of the stage exploded on landing but the top section had enough velocity not to be blown clear of the barge?

Maybe this is old news, but has anyone else noticed the "Auxiliary Powerplant Cooling System" so masterfully installed above the foremost thrustmaster plant?

Yeah I saw the redneck cooling rig that was setup :)   SpaceX is not above strapping down a ladder and a hose to  "get er done" :)

I am wondering if the blast damaged the fans on that cooler and they needed to hose them down to keep the TM from overheating.   I doubt that was there pre landing.

Going back and looking through images, I do not see it there before it left port. Maybe it was related to the "landing".

Anyone else notice the Oil containment boom  floating around the base of OCISLY. Probably due to damage to the damaged thruster leaking diesel. observations? :o :-\ ;)

For one I see the a Thrustmaster dragging in Marek's pictures.

Panorama taken from another vantage point - shows Thrustmaster damage.

Very nice. It shows the four-leaf clover is still there, albeit blackened-over. The big fat mark on the blast-wall to the left of the four-leaf clover suggest that at least some part of the first stage hit the blast-wall there.
And that Thrustmaster on the left seems to be dragging alright. There is all sorts of debris right on top and next to the supporting equipment. And guess what is right behind that debris: the cherry-picker. You would almost think that Falcon 9 mad another attempt at flattening another cherry-picker.
Definitely the interstage and top of the upper tank under the tarp. There is clearly a grid-fin sticking out. I'm amazed just how much of the stage is actually still on deck given that clearly hit the ASDS pretty hard.
Also, the blast-wall obscures most of the containers behind it. Lord knows what other wreckage-and-damage is behind the blast-wall.

Remember that the barge is usually ballasted to be low in the water for stability during landing.  The list could just be a pump problem with that side, couldn't empty the ballast tanks out.

Yes, there appeared to be a stream of water being pumped out of the barge, exiting at the front of the barge below deck level, as it was towed past the Port Canaveral webcam. So evidently not all the ballast water has/had been pumped out yet.

It is possible that the Thrustmaster and its associated hydraulics are intact, but the did not want to move it into the stowed position because of the rocket bit that are all over it.

2) It's scary - but I am beginning to think that the "list" we are seeing in these images, where the starboard bow is low could actually be quite the opposite. I think that the entire barge has buckled slightly in the center aft, thereby lifting the starboard (and maybe port) sides. Look at the aft blast wall compared to the deck and you'll see what I mean. Perhaps the F9 came in so hot that it bent the deck upwards. Seems impossible, but perhaps...

I think you might be being misled by the panorama here.  Since it's multiple images stitched together from slightly different camera positions/angles, you can get some subtle warping which isn't actually present in reality.  There might be some lens distortion in the single-camera photos as well.

What do people think is that assembly behind the guy with the broom?
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

Two things -

1) I don't see any thrustmaster damage? Where are you looking?

2) It's scary - but I am beginning to think that the "list" we are seeing in these images, where the starboard bow is low could actually be quite the opposite. I think that the entire barge has buckled slightly in the center aft, thereby lifting the starboard (and maybe port) sides. Look at the aft blast wall compared to the deck and you'll see what I mean. Perhaps the F9 came in so hot that it bent the deck upwards. Seems impossible, but perhaps...

Could those two things be related?
Could they have induced the list to have the dragging Thrustmaster ride higher in, or out of, the water for the return trip?
Seems much more likely than bending the entire ASDS.

Hopefully that Thrustmaster itself is OK, but something easier to fix is why its down. Such as damaged hydraulic lines between it and the pumps. 

I'm not familiar enough with the deck layout to know where the pumps and control systems are located, to attempt to tell if those might have gotten damaged. Those would be harder to fix/replace soon than lines in between them and the Thrustmaster.

Does anyone guess how the upper part of the stage could stay on the barge?

I think the GoPro video from the other end will answer that question... whenever it's made public...
My guess... is it landed just off the side and the top toppled onto the barge...  ???

The video... if released should be  :o  I'm thinking...  8)
