Why is everyone mad about Artemis I working though? SLS’ success is tied to Starship now so too.

Takeaways from Tim’s vid
>Raptor 2 is skinnier and simpler than Raptor 1
>Outer Raptor 2 engines won’t gimbal on Superheavy
>SpaceX has blown up 20-30 Raptor engines in testing, and melted 50+ combustion chambers
>A Raptor who loses its combustion chamber CAN be repaired if the part is replaced. Wow.
>Cooling on Raptor 2 is very hard. SpaceX purposely cuts performance on Raptor 2 to keep it cool and safe.
>Raptor 2 has no torch igniters around the main chamber, unlike Raptor 1. No one knows how it lights even, except Elon.
>Startup on Raptor 2 is very very hard but it runs smoothly

Will post more in a sec
