I don't recall that we've ever seen TEA-TEB on the rocket body before, just in the inside of the engine bells.

Guys, I'm headed for home. Wish me luck!
The powder is white. The old legs were white. The new legs are black. QED

QEDWhy then did we never see the residue in the engines which were not lit for landing? I doubt there is enough residue to make it all the way to the legs as we see here. I suspect it is more likely simply "ablated ablator".

Published on 18 May 2018- http://www.americaspace.com- http://www.facebook.com/AmericaSpace.org The new Block 5 verision of the Falcon 9 booster will have the capability to refold its' legs after landing to enable faster turn around. This flight, being the first of type was being handled differently. On return to port day, we saw that they were removing the hydraulic lines from the leg towards the water and figured that restowing wasn't going to happen this time.About half way thru the time lapse, dust clouds apper from the right as the dock to the East was being swept. It looks like the dust wasn't blowing directly on the Falcon, and no one grabbed the covers for the engine nozzles.Credit: Jeff Seibert / AmericaSpace.com
This is indeed interesting. Why did they remove the legs instead of refolding them?

They have been working recovered stages for awhile now.

They WANT TO do it.They want to inspect the first flown B5 booster very carefully in order to make sure they can throughfully evaluate the condition of all the parts in it.QuoteThey have been working recovered stages for awhile now.... from earlier F9 models. And they have found out that certain parts suffer damage and then they have tried to strengthen those parts. Now they need to make sure the improvements they have made have worked.

Shipping a booster isn't like an Amazon Prime delivery. It's expensive and it's a potential risk for the booster, not to mention the lost time, in weeks, in shipping.
