To give you an update on OCISLY...

You may notice that this is the wrong direction... So yes... today is NOT arrival day.

I need to see what they are up to before advising an arrival time.

I've analyzed this now: They have turned so that they are no longer sailing into the wind and are instead sailing with it.

If they were not able to use Octagrabber, they may have an unhappy, wobbly, booster that is secured with chains and more prone to issues...

OCISLY is approaching Port Canaveral. Arrival time looks like 4 - 6am EST. However, there are three cruise ships due at the same time that will get priority.

On a rather gray day (this Saturday morning) one can see the recently launched SpaceX Falcon 9 booster returning to Port Canaveral around 7:15 am local time. I apologize for the poor photo quality. #SpaceX #portcanaveral

The booster is on jacks.  #SpaceXFleet

Riding low with jack stands and chains, B1051.3 is inbound to North Cargo Pier 6. Recovery teams have been on mission since late January 16th. #Starlink #SpaceX

Don't think I've  ever seen that technique before.  Like they don't want to put any more load on the legs than they have to.  Seems like the recovery team is well prepared!

Have a good one,

This method was always used on JRTI, and also on OCISLY before OctaGrabber.

THanks, I'll have to go back and re-learn.  I thought they just chained down against the legs themselves, without the jacks.  This way makes more sense, though.

SPACEX Starlink Booster 1051.3 returned to Port on a rainy foggy morning sitting very low on OCISLY & with a distinct lean. The engine bells are closer to the deck then I have seen before. Be interesting to see what damages are done.

Falcon 9 booster as it returns to Port Canaveral. You can see some personnel near the lower right landing leg. I believe this is the second booster to have launched from all three of SpaceX’s launch pads (last one was the first but did not survive the in-flight abort test).

The amount of bellyaching about this "hard landing" is pretty amusing. The landing appears to be getting worse in every retelling, like a game of telephone.  ???

I'd wager this wouldn't even hit the top-10 of "barely made it" sea landings, keep in mind that signal cutout have prevented us from seeing landings with this quality in previous launch streams. There have been plenty worse, that I am sure of.
Its used nearly (it is leaning a bit) all the crush cores, I don't think any of survived boosters used it in all legs, Also no OctaG.

Previous landings distance from deck to bells is ~1.8m and with this landing it ~0.5m

A closer view of Starlink Booster 1051.3 at Port revels the  engine bells are close to the deck & it appears that it was too low for @octagrabber to be used. Instead jack stands & chains were used to secure the booster. #NASA #SpaceX #Space #Starlink

Notice the dent in the attachment pin on the left hydraulic strut apparently caused by the hard landing

Can somebody draw tighter red circles, couple of arrows +maybe green dotted lines, coz I don't see it.

If that's indeed a dent, it indicates the crush core got compressed so much that it could no longer protect the wall.

That's real wear and tear on the body...  I wonder if SpaceX has an internal classification for boosters that will only be used for internal (Starlink) launches.

Same here. Dent? Perhaps there is one, but it is not clear from the pictures so far.

It's hard to tell.  Need a profile shot of that leg cylinder.

I think it's an optical illusion due to the cable not being straight.

A huge cloud of smoke or steam just came from the #SpaceX booster sitting on OCISLY. It had mostly dispersed by the time I got a picture. #SpaceCoast

I am having a hard time telling if there is a dent or not, but I'm leaning towards there being no dent. If there is indeed damage, I think this would seriously set back the turnaround time for this core. We will probably never know what caused the hard landing unless Elon tweets something, and hopefully they can avoid a repeat of that on the next mission.
