> You don't simply fill it up and relaunch.

Yes, you do. Or at least, that's what they want to do. They've already reflown a bunch of their landed rockets, including the two boosters on Falcon Heavy. The ultimate goal is to be able to fill it up and relaunch, and the ultimate motivation for propulsive landing is simple - that's what is needed on Mars (parachutes won't do much there), so they want to master it.

EDIT: I meant that today, with Falcon Heavy Test Flight behind us, the two side boosters qualify as reflown - this was their second mission, not the third.

So the FH boosters were reused? The ones that landed back again? Amazing, great news to start a morning :)

Yes!

The left booster "originally launched on July 18, 2016 in support of the CRS-9 mission, and landed back at LZ-1". The right booster "originally launched on May 27, 2016 in support of the Thaicom 8 mission. Notably, it earned the nickname "Leaning Tower of Thaicom"; having developed a significant lean upon a hard first landing."
