Going to be interesting to see it back in port with scorch marks ;)

Elon Musk: Ship itself is fine. Some of the support equipment on the deck will need to be replaced

Real shame about that, guess our chance of seeing video is gone. :(

Fire, or just impact?  Back to Louisiana or locally repairable (where are the local shipyards?)?  Ready for 1/29 attempt? 

EM: didn't get good video,,,, have actual pieces

why?

to me, it is already impressive that they actually hit the barge. I expected that they might come down within 1 km around the barge, but hit the water.

the real question is now: did the stage remain on the barge, or did it tip over into the water and sink?

I think there a good chance we don't see it on our favorite webcams.  If there is damage to support equipment, won't it go back to the ship builder that did the original outfitting?

I just hope it can be ready in time for the next launch!

Didn't get good landing/impact video. Pitch dark and foggy. Will piece it together from telemetry and ... actual pieces.

Seems that it blew up - but getting at least some of the pieces back is still phenomenal.

I'm going back to bed.  I want pictures on my desk by the time I get back up.  Is that clear?

Yes big question is whether the ship can be repaired in time for DSCOVR flight at end of january.

Good luck to the GO QUEST crew, how are probably fighting fires and fishing pieces out of the Atlantic in the dark right now.  Still --- what a job!

Duct tape will do.

And I think those things crew were checking on before deck departure align with ballast tank positions...need to look just a bit harder but that later "P

Those are clearly cryogenic tanks to fill the internal reservoirs for re-flight.(*)

*) probably not

If the ASDS started heading back to port (not shipyard) right now (unlikely), how long will it take?

Under a couple of days.
I guess it depends on where and how much damage has occurred.
Fuel tanks are probably easily repairable, for example.
Thrusters might have extended lead-times, and if one or more thruster hydraulic pumps or engines are damaged, there may be extended lead-time sourcing new ones.

It might go a little slower back than out if they cant use the thrusters - if they even used them during the transition. What will take longer time is getting back aboard, securing everything and assessing the damage before they can even get started back. All depends on the amount and type of damage and debris, there might even be fires to put out (small amounts of RP-1, larger amounts of diesel fuel). Didn't sound that bad from Elon's tweets though.

~35-40 hrs

Barge should be back in port Sunday night. Fascination is due in port Monday morning, so we may get a good view of debris removal/cleanup activities.

Indeed. The fact that it made it to the barge proves that pinpoint landings with returning stages is possible. Another BIG first for SpaceX.

If the stage hit the barge hard enough it likely would have resulted in cracking the pressurized stage open. Not a good thing when there still is kerosene and LOx onboard. IMO there will have been some sort of 'boom!'.

Sounds like the hydraulic system was likely made inoperable on one or two of the thrusters. Which would mean they'd be stuck in the down position. I guess they'll have to spend some time dealing with that. Might just connect new hyd hoses to quest temp and fold them up?
