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

AFAIK this was it's 6th flight

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

Great trip. @SpaceX so impressive.
- "Hope" and I put on spacesuits. Functionally and visually . We announce her in 36 hrs!
- More mission details soon, but will be interesting to look down and maybe @Space_Station or @NASAHubble. Experiments and payload progress too

Go for launch: The FAA has granted SpaceX a launch license modification for Starship SN10. So we could see a flight this week as Elon said, pending successful static fire, which could come as early as today.

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.

I like the idea of the floating platform. It would be much more secure for those people who live nearby and they will not complain about the noise and inconveniences the preparation for the launch and the launch itself can cause.

 

[Josh_TN]

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.

 

[TomcatViP]

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.

Starlink broadband speeds will double to 300Mbps "later this year," SpaceX CEO Elon Musk wrote on Twitter this week. SpaceX has been telling users to expect speeds of 50Mbps to 150Mbps since the beta began a few months ago. From a report: Musk also wrote that "latency will drop to ~20ms later...

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.

Engine shutdown led to failed Falcon 9 booster landing - SpaceNews

A Falcon 9 first stage failed to land after a launch last month because one of its engines shut down during flight after hot gas breached a worn-out cover.

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.
