Sooo, if it lands, who will be the first to reuse it for a third time?

Will they ever get to a point where there will just 2 pools of rockets. "New" and "used" regardless of how many times?
It's unlikely the current boosters will get more than one reuse. Block 5 coming later will.

The static fire test was completed OK, so on to the main event.

Do you have a source for that? Not calling you a liar, but I've not seen any statements as to yea of nea on multiple reuse.

"“Falcon 9 Block 5 — the final version in the series — is the one that has the most performance and is designed for easy reuse, so it just makes sense to focus on that long term and retire the earlier versions,” he wrote. That version includes many “minor refinements” but also increased thrust and improved landing legs, he said."

"It now seems likely that SpaceX will fly the landed boosters it currently has, at most, once or twice, before retiring them, instead of multiple times"

Doesn't seem exactly unequivocal, I'd really expect them to make a judgement call on any returned boosters. If reuse saves money then not reusing perfectly healthy boosters would seem daft to me; of course I'm not privy to how much/little damage a launch causes.

We shall see.

Its taken them 4 months to prep this booster for relaunch.

Once block 5 boosters are flying these wont. Block 5 are due in what 6 months or so.

How many reuses do you think they will get out of these ones before then?

It seems likely that both side boosters of the f9h tester will be reused ones.

Has it? For all you and I know it was ready 10 days after recovery; there's more to this than just the technical aspect. As to how many relaunches per booster? I don't know but storing them has got to be an unnecessary expense if you don't intend to reuse them. We'll see, second guessing Elon Musk is a mug's game, he'll do that which drives him on to Mars at the best possible rate.

Yeah spacex have gone to the trouble of developing and certifying a whole new bock of f9 1st stage boosters because the current ones are just fine.

They've undoubtedly spotted issues that could make their new vehicles more reliable, they've been constantly improving their designs since their early failed F1s. Doesn't mean that the currently landed boosters aren't capable of multiple relaunch (or that they are for that matter), although I'd agree that I'd expect the block 5s to be more capable.
You seem angry, why? SpaceX will use their boosters as appears good to them, and neither of us knows what that will look like at this juncture.

angry because you seem to be doubting all the fking evidence and living in your own dreamland.

"Recovering and refurbishing the used rocket booster that's reflying next week took SpaceX roughly four months, SpaceX President Gwynne Shotwell said on a panel at an industry conference in Washington earlier this month. Eventually, the company says, that turnaround time will drop to a single day as SpaceX aims to refly rockets much in the way airplanes operate today."

https://en.wikipedia.org/wiki/Falcon_9#Falcon_9_Bl...

On October 23, 2016, Musk described a Falcon 9 "Block 5"[clarification needed] version that would have "a lot of minor refinements that collectively are important, but uprated thrust and improved legs are the most significant."[78] On January 21, 2017 Musk added that the Block 5 version "[s]ignificantly improves performance & ease of reusability".[79] He described this version as the "final" version of the rocket. Block 5 is expected to start production in early 2017 with the initial flight in the second or the third quarter of 2017.[78]

This is slightly less equivocal than your previous evidential offering; I had not seen it. You'd still probably do well to chill out a little though dude, your reaction seems a little, shall we say, disproportionate. I don't live in your world, but I don't live in a dreamworld either. Asking for evidence that I didn't have, and you apparently did, is hardly accusing you of having a tiny penis.

Doesnt come across as an aggressive arse at all. Just because you havnt seen anything it must be made up. I'm not going to prove every fking word I say here. This is the last time I reply to you.

Too much anger on display folks. This is supposed to be a smart section of PH - not an area for rowing.

You thought that was aggressive? If so I apologise, it wasn't intended to be. I do think you may be a tad hypersensitive though.

FWIW I read an article a few days ago that mentioned 4 months of refurb work on this core. I can't find it right now, I think it was on SpaceFlightNow.
They didn't expand on "4 months" so no way to know what that means in terms of man hours or cost, or how much extra precautionary work might be done due to this being their first go at it.
