The fairing looks spotless. I guess they’re using a new one, at least partly for reasons of cleanliness? (Planetary protection and all that.)

With boosters we’re at the point where “flight proven” is no longer just a euphemism for “second hand”. I’ve felt that way myself for a few years. And NASA basically confirmed they agree a couple of months ago, when the brand new booster intended for Crew-9 was given a Starlink mission first, increasing confidence in it after a minor problem during transport. (IIRC)

But I’m not sure if we’re at that point with fairings. Or even if we’ll ever be.
