How many flights did that booster have under its belt? SpaceX seems to generally use its highest mileage boosters for in house launches.

Regarding the booster loss on Starlink L19 mission whilst attempting landing.

Comparison of booster accelerations around time of entry burn - blue is last night's flight, red is from 2 weeks ago.
It's not a full 33% reduction in thrust so it wasn't a complete engine failure.
Afterwards you can see aerodynamic drag rises faster before loss of telemetry

Decreased drag likely due to control system not aiming for the droneship after a detected anomaly

It's consistent with it simply being deeper in the atmosphere at a higher speed

changes a Boca Chica

New Launch pad
The Round foundations are so the worker for LOX, LCH4 and Water Tanks
They drilling next the Launch pad deep holes for concrete foundations,
for support Tower/Crane ?
in mean time the support ring for launch pad get completed

Nose cone of SN15 feature strange difference
instead header tank there plate installed

After a record breaking engine swap, SpaceX static fires Starship SN10 for the second time this week. If the test was successful, SN10 is now ready for flight.

The ocean also provides a pretty handy abort mode. Just kick the rocket a couple hundred meters in any direction. I wonder though if the two rigs they bought can be adapted; I'd think there would be issues with center of gravity with a full up booster/starship. It's the weight USN destroyer; I'd think the vehicle could only be staged from the center of the platform. SpaceX would also need a fleet of ships to move boosters, starships, and fuel to the rigs...I can't imagine they could fuel more than one complete mission from locally stored fuel. But it probably is still easier to operate on the water rather than deal with all the issues of local inhabitants that will always be an issue unless you owned hundreds of square miles.

Whatever choice they take, the rig approach will induce a lot of, probably yet, unforeseen constraints that will affect their reach for a quick expansion. It's a bad idea.

Why the Falcon 9 didn’t land last month. It seems due to sheer re-use, that a particular component failed causing loss of an engine because that component was a life leader in its number of re-uses it had experienced. No Falcon 9 had seen so much re-use of that component. If your pioneering this sort of thing then I guess you can expect things like this.

I guess all these isues with floating platfororm will be solved till engineers sart building of this platform. As you have mentioned this is much better to lauch Starship somewhere from a sea than from the ground frome some specialy prepared area.
