I would love to know how they prevented flow separation when they fired a vacuum optimized engine at sea level! Normally the pressure at the end of a vacuum nozzle is so low that the ambient air pressure will separate the flame from the nozzle and destroy the engine! @elonmusk

@Erdayastronaut Raptor has a very high chamber pressure, which in turn allows for a large expansion ratio nozzle without flow separation at sea level
@elonmusk @Erdayastronaut Going for another 🔥 tonight?
@elonmusk @Erdayastronaut Looks like some TPS tiles fell off during the static fire. Do you think this will be a major issue for the orbital launch or does the team already have a solution?
@Erdayastronaut Currently at ~270 bar, but working on upgrades to get it over 300 bar
@elonmusk @Erdayastronaut How soon is the target for orbital launch?
@elonmusk @Erdayastronaut Hey Elon, how do you feel about #Dogecoin these days? 🐕❤️
