That was absolutely incredible. It looked like most of the flight went just as planned except for the engine relight at the end.

- enraged_camel 6y agoYeah, a few seconds too late to re-ignite is what it looked like. Great test though!
- endymi0n 6y agoFlame looked very green very late, looks like they might have burned through quite a lot of TEA-TEB trying to get that candle lighted but it didn't react as expected...
- CarVac 6y agoThe Raptor doesn't use TEA-TEB, it uses an augmented spark igniter.
- Gwypaas 6y agoMaybe some metal in the engine burning, you could see some green streaks at the edge right at the relight. Engine rich combustion?
- CarVac 6y agoYeah. https://twitter.com/elonmusk/status/1336809767574982658 https://twitter.com/elonmusk/status/1336809767574982658 The fuel flow must have dropped, leading to oxygen-rich, and then engine-rich combustion.
- CarVac 6y agoFrom Everyday Astronaut's slow-mo replay, it looks like two engines both relit properly, and then one shut down (intentionally), and then the final engine throttled down and turned green.
