“@John_Gardi @SpaceX Yes, aiming for 380 sec Isp with vac nozzle. Maybe 382 if we get lucky.”

“@13ericralph31 @SpaceX I think 6 where we lit main chamber & several with only preburners”
“@johnkrausphotos @SpaceX About 11 secs”
“@alexmd2 @SpaceX Definitely! It’s amazing that the RD-170 & RD-180 engines held the record for so many decades. Excellent engineering.”
“Raptor reached 268.9 bar today, exceeding prior record held by the awesome Russian RD-180. Great work by @SpaceX engine/test team! https://t.co/yPrvO0JhyY”
“@rocketisfine @leo190102 I was simply too sexy for it https://t.co/vugJLyZVjI https://m.youtube.com/watch?v=P5mtclwloEQ”
“@leo190102 Maybe tomorrow”
“Just left Zeebrugge, now Tilburg, then Tesla HQ in Amsterdam & Oslo tonight to review service in Norway. Exciting to see thousands of Model 3’s on their way to owners in Europe! https://t.co/PeRo4jhiCB”
“@westcoastbill Hope they don’t find this pic! https://t.co/vwUJhFyWmS”
“😅 thank goodness it’s not November”
“@Bkin87 a”
“Send me hot pics & I’ll be right over 😉”
“I want you too baby”

“@Erdayastronaut @LytovchenkoSerg @John_Gardi Booster center of mass is much lower & more consistent (no payload mass to consider), so still biases towards engine first entry”
“@LytovchenkoSerg @John_Gardi @Erdayastronaut Technically, the steel is radiatively cooled (not uncooled). T^4 is one of the most interesting things about reality!”
“@LytovchenkoSerg @John_Gardi @Erdayastronaut Rocket booster temperatures won’t go much above 600 Kelvin on hottest parts of main body & maybe around 1200K on base, which uncooled steel can handle. Starship is around 1700K for a Mach 25 entry, so needs shielding of some kind.”
“@Malcolmmarsman @Erdayastronaut Prob wise for version 1 to have legs or we will frag a lot of launch pads”
“@Erdayastronaut Welded, internal, longitudinal hat stringers. To the degree it may need hoop stiffness (prob not), combine with slosh baffles.”
“@Erdayastronaut The Super Heavy booster is only needed on Earth, so think of this as just “Starship” & sometimes it needs a boost, hence Super Heavy”
“🔥🖤 SpaceX Engineering 🖤🔥”
“@OctagonROA Telekinesis”
“@AndreTI Vaporized some copper”
“@teslaownersSV @StrikMichael @JothamKitara Sentry Mode (and Dog Mode) roll out next week”
“Design requires at least 170 metric tons of force. Engine reached 172 mT & 257 bar chamber pressure with warm propellant, which means 10% to 20% more with deep cryo.”
“Raptor just achieved power level needed for Starship & Super Heavy https://t.co/NcqnAVWc35”
“@StrikMichael Sorry, many unexpected challenges with cars coming through Zeebrugge first time. Cars will start moving out in volume tomorrow.”
“@SpaceX https://t.co/sO2s0OcM4L https://www.whereisroadster.com/charts/”
“@FancyPantless We’re doing everything we can to get there. It’s a super hard grind.”
“@notNahuel @SnazzyQ Exactly. Both prices are shown right next to each other & lower price is *actually* the real apples to apples cost vs a fuel car. In fact, for many states in the US, it’s way better.”
“@Gargant44992081 VAT of ~20% & import duties of ~10% usually result in a 30% higher cost in Europe”
“💙 Mach Diamonds 💙”
“@joerogan Glad you like it”
“@psalman03 @Erdayastronaut @dguisinger @DanielDavisA Spark plugs ignite dual blow torches that ignite preburners & main chamber”
“@Erdayastronaut @dguisinger @DanielDavisA Gaseous CH4/O2 & heavy duty spark plugs. Basically, a 💨 of insane power 😀”
“@jclishman @dguisinger @Erdayastronaut @DanielDavisA Will do, although SpaceX reddit is very well-informed. Really impressive analysis by some commenters.”
“@dguisinger @Erdayastronaut @DanielDavisA Engine use methox torch igniters. Green tinge is either camera saturation or a tiny bit of copper from the chamber.”

“@crazyhank @Tesla Haha how is this even real?”
“@Darkaraus_ @Zanfa No, payload will actually increase”
