Video has appeared taken from a cruise ship showing ship 33 exploding.

Here it is reentering, photographed from the Turks and Caicos.

Sounds good if that pans out, but the FAA will surely demand wearing of sackcloth and ritual ashes sprinkled on the head as penitence for unscheduled debris streaking across the Caribbean sky.

OTOH, it won't be Biden's FAA anymore (old expectations die hard).

Preliminary indication is that we had an oxygen/fuel leak in the cavity above the ship engine firewall that was large enough to build pressure in excess of the vent capacity.

Apart from obviously double-checking for leaks, we will add fire suppression to that volume and probably increase vent area. Nothing so far suggests pushing next launch past next month.

The FAA says

"The FAA is aware an anomaly occurred during the SpaceX Starship Flight 7 mission that launched from Boca Chica, Texas, on Jan. 16. The FAA is assessing the operation and will issue an updated statement."

This looks very similar to the problem that caused the Flight 2 ship to explode. So it was a vulnerability that they were already aware of. They obviously hoped that the mitigation measures they put in place then would be sufficient, but probably realized that they might not be.

I hope that the Version 3 Raptor engines eliminate some of this problem. Elon says that he absolutely hates flanges and seals on rocket engines because at the temperatures and pressures at which rocket engines work, preventing leaks is a huge engineering challenge. The solution on the Raptor-3's is to 3-D print as much of the engine as possible as a single unit.

I also note the 'next launch next month'

SpaceX has just filed a proposal to construct a huge "Gigabay" vertical assembly building at Cape Canaveral, presumably for final assembly of the new stretched Starship ships and boosters

They have transported the pieces of the catching arms for Tower-2 from the Sanchez work area to the launch site, where they are being assembled and prepared for mounting on the tower.

The new Arms are being lifted to Tower-2 and attached as I write this.
