Not sure I understand, "block 1 solution". Wasn't this booster upgraded to block 3?

I think that might be a reference back to the first stages that were recovered where there were fuel fires on deck visible in the landing footage after engine shut down.

The deck looks extra toasty.  Maybe that "block 1 solution" brought back the post-landing RP-1 discharge issue.

Edit to attach an image from the above link.
I didn't see any flames after landing.  I suspect the touch-up job on the deck hasn't been 100% each time.

Touch up seems pretty decent if you look at pictures of the deck just before OCISLY left port, but agree that it is probably just blast damage from landing and not due to fires seen in the past. Seems to get toasty right before touchdown.

Another picture from earlier. Posting it as I think the cranes are giving a fitting salute to a returning (and retiring) booster  ;)

I was thinking that the new touch up paint might not adhere to the landed-upon deck quite as well as when "factory fresh", so even though they repaint after each landing it ends up looking "worse" each time.  It's all cosmetic anyway.

They might switch to an ablative coat that can be quickly applied and removed. Something that provides good thermal insulation, and protects the core from re-entry heating. Better ablative paint would allow them to try even hotter landing which use shorter re-entry burns, and in turn with the stronger titanium grid-fins allow them to glide and aerobrake.

Edit: hmm, I think Turner anticipated this by about 179 years. Two brave ships, being towed to their (near) final resting place  ;)

I've responded to this on the refurbishment thread.

Actually I think it's a reference to statements made by a SpaceXer (or ex?) on reddit about the refurb process, that this booster had some parts in it that weren't planned for, and didn't have part numbers (since they were done on the assembly line and subsequent boosters had part numbers for them), and when they replaced things, since it was a block 2, some of the block 3 things they tried to replace didn't fit, or didn't install as expected, so they used "block 1" techniques to do a few things.  I don't recall the thread right now but it might be the refurb one, not quite sure. It sparked off a pretty good discussion about whether SpaceX has their processes under control and are repeatable, etc. Which I'd rather not see us have here.

We don't have the level of detail to know which parts or to speculate on whether that is why there was so much burning (the legs are on fire in the landing vid).  https://www.instagram.com/p/BSfJDjMFzwR/ ... discussed starting here http://forum.nasaspaceflight.com/index.php?topic=42544.msg1663655#msg1663655

Is the "soot" really soot from RP-1 or desublimated (depostion) PICA-X? (which is also a soot...)

There is no pica-x on the booster.
With ELV best efficiency was the paradigm. The new paradigm is reusable, good enough, and commonality of design.
Same engines. Design once. Same vehicle. Design once. Reusable. Build once.

There is no pica-x on the booster.
But there is "SPAM", which is an ablative coating also.  The question is, what does it become when it ablates?

A cam other than *you know who*.
Can't see much, but can see stage is still vertical.

This video is from CRS8 about a year ago. According to the "Orlando Princess" web cam, S1 is still vertical.
