@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered. Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb. Booster is purging all 33 engine shrouds in flight to prevent this. — PolitiTweet.org

@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas. Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster. — PolitiTweet.org

@DJSnM @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes. — PolitiTweet.org
