I don't know for the US market but for French/European market there is a database of the reliability and reparability of appliances brands.

Hydrogen leaks ! Dihydrogen is the smallest molecule so it can pass through the smallest smallest gap.
Containing hydrogen is extremely difficult and it is an extremely difficult challenge for rocket manufacturers.
C'est la merde !
Same thing, I'm mostly using the GPS on my phone but unless I try to always carry a paper map with me as a safety.
A picture off the interior
My parents had one when I was a kid, the second version was not to ugly and the interior was crazy comfortable for a family car.
It had 3 full front seat and 3 full seat in the back too.
They are expecting a very active hurricane season this year, they might manage to lose a ship or two
It is estimated that currently each starship launch is cost around $90 million, and should be around $10 million once the program is more mature.
For comparison each SLS launch is estimated to be around $4.1 billions. This cost not include development.
So a Starship launch is around 40 to 400 time cheaper than the SLS for similar capacity in LEO.
Destructive testing has always been part of every engineering development projects.
When developing new parts it's common to make a lot of test parts and stress them to failure to see how they react.
For innovative design it can take several iterations before finding the right material/design. Each destructive testing is bringing valuable information.
Knowing exactly how a part will fail gives extremely valuable information on how to build a part that will NOT fail and everyone does that including NASA.
SpaceX has just brought this philosophy to whole different level by doing destructive testing on the whole rocket. The best example is that on the last flight they purposefully removed heatshields on some area of the Starship and added sensors in the area to see how it would impact the ship.
The can afford to do that because they focused on building a rocket factory to mass produce starships rather than building a rocket. It means that even if they were not launching it the factory would still produce Starships.
PS: SLS is not 10x the cost of Starship. According to an independent report ( source ) Right now the estimated cost of a Starship launch is estimated around $90 million, one the program is operational the cost of a Starship launch is estimated to be around $10 millions.
A SLS launch is estimated to be around $4.1 billion
So a Starship launch is 40 to 400 time cheaper than a SLS launch
I would not have believed it in a Sci-Fi movie. Having the heatshield failed on the flap for most of the descent, seing the flap burning in flame and still managing to land softly after that !
What kind of plot armor is that ?
It is incredible that the ship survived that and really shows the kind of resilience starship has !
The live was such a rollercoaster of emotions.
The moment the fin started to melt I thought this was the end of it, but it still hold on, and hold on. Then the image disappeared do I though that was it, but no it continued after that, we get the image back.
I start to think that it might be able to crash on water, maybe not in one piece but it would be a big improvement comparef to the last launch, especially since they already soft landed the booster.
And then it get a few km away from water level and at the last minute it DOES THE BELLY FLOP AND SOFT LAND ON WATER !
I had absolutely zero hope of that happening !
Ejaculation lower the risk of prostate cancer, so masturbation should probably be medically advised to all men.
4-7 times a week is a good number according this study
