Great view of Roomba, cropped from a photo from Twitter user @NASANate. Intriguingly, below the roasted Roomba there appears to be something the exact dimensions of Roomba taking a similar octagonal shape.
I'm actually more intrigued by the burn pattern on the deck. Last rocket came in at quite an angle from the looks of things. Another photo on the Koreasat update page looks down from above and the burn appears to run right off the side of the deck.
There was quite a lot of fire post Koreasat.Is unclean engine shutdown, spewing all of the remaining fuel on the deck, where some of it flashed into a messy fireball coating a side of the stage, and some ran off on fire also a possibility?

I would expect helium for sure. Maybe some hydraulics. Some electrical probably. Maybe kerosene, I'm starting to believe, because I have yet to see any other umbilical connected to the first stage fuel tank in photos. - Ed Kyle

Here's a short video I made of the post-landing fire. I still think I see flames coming first from an engine nozzle. - Ed Kyle
Purging residual kerosene would be through the nozzle, no? So the nozzle is the least surprising place I'd expect to see the flames begin.

So the nozzle is the least surprising place I'd expect to see the flames begin.Actually, kerosene would be the one thing I would think they wouldn't purge. Two reasons: (a) an oil slick on the ocean would be frowned upon by the ever-watchful greenies and (b) an oil slick on deck could potentially stop the Roomba 'sticking' and would also be extremely hazardous to the boarding crew.I'd say they got a stuck valve someplace on the stage...
Could it be that residual kerosene is usually deliberately burned off in the engine... But somehow that process has gone a bit awry? (Maybe a stuck valve, maybe a leak, maybe just strong wind or unexpected pooling.)
I went to the port today and noticed GO Searcher has some new hardware installed. Wondering what is it for...
