Not sure what to make of this....

BBC speculation about it being from CRS-7 are probably bunk, so much stuff growing on it that it is almost certainly an older bit. Perhaps from one of the soft-landed-to-ocean stages like CRS-3 or the first OG2 launch.

Here are some more images, later today there should be even more hopefully with part numbers.

Well it used to be a rocket part, now it's a veritable floating civilization. Those mussels(or... whatever they are, possibly space worms) are probably ready to develop their own space program by now.

Looks like part of the interstage. Photo for reference from CRS-7.

Given a North Atlantic Drift current speed of around 0.2 knots, it looks to me like it would take around 17 months to drift to England. The OG2 launch occurred right around that time, July 2014, and it soft-landed in the ocean, so the interstage would have been mostly intact.

So timing and landing conditions appear to be consistent with an OG2 interstage.

It's a large section, I would tend to think ocean landing rather than CRS-7 too. I'm still surprised by the muscles: Not even MH370 wreckage had that amount on. Different ocean of course, though.

I live not too far from Lands End in Cornwall - the closest mainland point to the Scilly Isles. This whole area is still living in the 1950's, not much happens here (and less than nothing happens in the Scillies) so the local press will be reporting on this for weeks...

Also, I don't see any evidence of grid fin mounting points on the interstage recovered, unless they sheared off somehow. The mussels are deep but I don't think they'd be deep enough to cover the fairly tall mounting point which, presumably, would be very sturdy to cope with the forces involved.

Pretty incredible to have part of a F9 wash up in the UK! Although all the locals had better close their eyes and not look at it, since it's proprietary US technology. ;D

But seriously, I hope it's returned to SpaceX free of charge. I assume it has some kind of serial number marked on it somewhere that SpaceX can use to ID it?

If I were SpaceX I'd worry: Have you heard of the pub on St Mary's that stole the timbers of a shipwreck to furnish their interiors?! :P

CRS3 didn't have grid fins, so seems a more likely candidate?

That launched on 18th April 2014, so 19 months ago - which would seem broadly consistent with the time to wash across the Atlantic.

Really don't see that level of marine growth happening in five months (this is one of the few things I can comment on from a position of some knowledge!). Again, 19 months would be much more consistent.

I'm no marine biologist, but I've had my time around boats to know that kind of biological growth definitely is 1yr + worth of time at sea.

Edit : More info : The article video cited the growth being goose barnacles. A quick search on Goose Barnacle growth rates show that it grows very rapidly in the first year (15mm (~1mm/mo)) then 2 to 3 mm/yr after. They are measured from their base to the filter tip at the top. Looking at the images above, even without scale, it seems most are pretty big meaning they are most likely a year + old.

Edit to remove spurious comment: Oh Scilly off the UK, not Sicily (Italy).  :-X The above still stands.

Why should the local council have to pay for sending it back to SpaceX. SpaceX can pay & collect it themselves.

I live closer to it than Chris B so I call dibs!

I wonder if they will attempt to clean off the barnacles to get a better look at the rest of it.

Well, the cleared part looks like a hand sweep. It would have been fun to be there as the American flag gets swept clean...

I'm a biologist by training and IMO there is no way this could be from CRS-7. Way too much (and too large!) biologicals on that piece for only 5 months in the Atlantic waters. It must be considerably older.
Given that it is a rather large intact piece it is probably from one of the early water landings. I agree with other folks here that this could possibly be part of CRS-3 or CRS-4 interstages. Those would be much better fits for the amount of biologicals versus time-in-water.

Edit: Id-work by folks on Reddit have this be part of CRS-4.

Salvaged, not stole. Please, don't impugn the good people of St. Mary's.

As far as the free return, is Elon giving free rides?

Depends, is there a suitably large concrete pad somewhere in England?  ;)
