This ain't a rocket it's a firework with an engine on

I used to be a knee like you, then I took an adventurer in the arrow.

Some also call it a flying grain silo!

In all seriousness though, even SpaceX had a number of failed launches with the Falcon 9 before a successful launch and recovery, so its not like there isn't proof of the effectiveness of their methodology given where their at in the industry today because of it. It would have been nice to complete the orbit and recover them, yes, but they've improved a lot from the last launch and will be rolling the next Starship to the pad before too long after their done analyzing the data and implementing improvements.

As reported by arstechnica:

SpaceX just got their FFA license and the 3rd Starship launch is nigh, scheduled for Thursday, March 14th, 7 am CDT. The previous launches failure was identified in two parts. First, the Starship rocket underwent a purge of excess oxygen to better simulate a reduced payload, unfortunately this developed a leak causing a combustion event, ultimately leading the onboard computer to trigger the self destruct. As for the Super Heavy Booster, it turns out here was a filter blockage in the liquid oxygen supply system, resulting in engine malfunctions due to a a loss of pressure in some of their oxidizer turbopumps, triggering the self-destruct.

There are some changes this time around having learned from these issues, but this flight will also be testing in-flight refueling technology, the payload bay doors, attempting to reignite a Raptor engine in space, and examine the performance of the heat shields on reentry. The current goal is for Starship to reach the Indian Ocean, with Super Heavy Booster reaching the Gulf of Mexico. They are both considered expendable, and are not intended to be recovered.

There several outlets offering live coverage of the launch, as of this post:

NASA Spaceflight starts in 4 hours and can be watched here.

LabPadre starts in 11 hours and can be watched here.

Everyday Astronaut starts in 4 hours and can be watched here.

The launch thus far was a relative success, with Starship reaching new milestones and gathering lots of new data. Liftoff was nominal and all engines fired without any problems. Boost back burn was also successful, with testing of the bay doors and propellant transfer results still being analyzed. SpaceX opted however to not test the re-ignition of its engines in space for this test.

Both Starship and the Super Heavy Booster however did not quite reach their respective destinations. Super Heavy managed to reach the Gulf of Mexico as planned, but while reaching the surface of the water it appeared to loose attitude control and starting wobbling, apparently having difficulty reigniting its engines, resulting in a loss of the vehicle prior to touchdown.

As for Starship, it managed to properly orient itself and reach the point of the Indian Ocean, providing spectacular views of the reentry plasma as it entered the atmosphere, things were going well until approximately 64 kilometers, at which point telemetry was lost and loss of the vehicle was called.

You can watch a recap of the launch here, starting at 8 hours and 43 minutes, just before launch.
