Booster 14-1 (first flew and caught on very successful Flight 5) looks to be the first Superheavy booster to be reflown a second time on upcoming Flight 9. It's currently receiving lots more attention than any of the other boosters in Megabay 1.
NASA has just added Starship to the eligibility list for their Commercial Launch Services contracts. That means that SpaceX can make proposals involving use of Starship for NASA satellite and interplanetary space probe launches. Previously they could only bid Falcon 9 and Falcon Heavy launches. This doesn't apply to crewed launches which would require Starship to be crew-rated, like Falcon 9. That requires much more stringent safety evaluation.

"Flight proven" (used) booster B14-1 which first flew on flight 7 and landed flawlessly while its ship blew up near the Turks and Caicos, is eager to have another go and is back on the launch pad for a round of preflight testing to start Thursday in anticipation of flight 9. That might include cryo pressure testing and/or a full static fire.

This booster first flew on Flight 7 and was successfully caught in Tower 1's loving arms
And now it's on track to fly again on Flight 9
SpaceX confirms that 29 of the 33 engines flew on Flight 7 and only 4 had to be replaced by new ones. All 33 lit properly for the static fire this morning.

Then Friday night two of these things rolled from the Sanchez work area to Pad B. They aren't couches for giants or huge Elon pipe organs. These are the flame buckets for the new Pad B flame diverter. One will fit on either side of the center ridge in the flame trench. The pipes will be fed with high pressure water through the manifold visible in the lower front, which will spray at high pressure out of many small holes drilled in the pipes, similar in concept to what happens with the water-cooled steel plate at Pad A.
Wasting no time, a crane lifted them down into the trench today. The two gaps where it looks like a pipe is missing are intentional, so the crane can get a balanced load. The last two pipes will be welded in after installation. There is still a heavy armored and water cooled ridge cap to go on top to take the direct rocket blast. But unlike the water-cooled steel plate at Pad A, the ridge cap won't have to take the direct blast of all 33 engines, most of which will be diverted out towards the ends of the flame trench.
Launch pad flame buckets and trenches have long been in use at Cape Canaveral (and by the Russians and others) and are a known technology.

Aerial photo that Mauricio took on Wednesday, showing the flame buckets installed in the trench. The two large green pipes at the very bottom will supply high-pressure water for the deluge.
After it lost more engines, a huge engine bay fire resulted. Control was lost and the full-stack started flipping end over end with the engines still running! (Few other rockets could stay in one piece doing that!) The flight was obviously doomed, but the aerobatics provided good data about the strength of the structure. Before flight there were worries that the structure wasn't strong enough.
A destruct command was sent and the explosives on the booster detonated first. Here's a leaked SpaceX photo from the ship after the booster FTS detonated showing the top of the booster still clamped to the ship, further proving the ability of the clamps. Then the ship was commanded to blow itself up.
