“@ikrbkv @MARINAVALOVA2 @alexmd2 @SpaceX A biography on Korolev has center place in my study”

“@SPEXcast @McMurchie @Robotbeat @John_Gardi @SpaceX Just planning on keeping the public informed about progress & setbacks. Will be some RUDs along the way, but excitement is guaranteed!”

“@McMurchie @SPEXcast @Robotbeat @John_Gardi @SpaceX The goodwill of the public is critical to Starship’s success”

“@epoxy101 @Robotbeat @John_Gardi @SpaceX At least 10X cheaper”

“@SPEXcast @Robotbeat @John_Gardi @SpaceX Very dependent on volume, but I’m confident moving to Mars (return ticket is free) will one day cost less than $500k & maybe even below $100k. Low enough that most people in advanced economies could sell their home on Earth & move to Mars if they want.”

“@SpaceXFan97 @Robotbeat @John_Gardi @SpaceX Yes”

“@Robotbeat @John_Gardi @SpaceX This will sound implausible, but I think there’s a path to build Starship / Super Heavy for less than Falcon 9”

“@13ericralph31 @John_Gardi @SpaceX Close”

“@John_Gardi @SpaceX But not an extendable nozzle though, as that just saves length. Nozzle diameter is limited by body diameter.”

“@SpaceXFan97 @alexmd2 @SpaceX Much above 300 bar main chamber pressure means extreme oxygen preburner pressure of 700 to 800+ bar. Definitely pushing the limit of known physics.”

“@_cgp @SpaceX Propellant was not deep cryo. CH4 & O2 were just barely below liquid temp at 1 bar. In theory, Raptor should do ~300 bar at deep cryo, provided everything holds together, which is far from certain. However, only 250 bar is needed for nominal operation of Starship/Super Heavy.”

“@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”

“🔥🖤 SpaceX Engineering 🖤🔥”

“@SpaceX https://t.co/sO2s0OcM4L https://www.whereisroadster.com/charts/”

“@jclishman @dguisinger @Erdayastronaut @DanielDavisA Will do, although SpaceX reddit is very well-informed. Really impressive analysis by some commenters.”

“First firing of Starship Raptor flight engine! So proud of great work by @SpaceX team!! https://t.co/S6aT7Jih4S”

“@TriTexan @SpaceX Yes”

“At @SpaceX Texas with engineering team getting ready to fire new Raptor rocket engine https://t.co/ACFM8AtY8w”

“@Trump_45th @SpaceX 7”

“@Archin50001 @AlexTheChemist @SpaceX Dammit! 😀”

“@AlexTheChemist @SpaceX Well, my past mistakes do seem extremely dumb, especially the ones where I mistakenly thought I was smart”

“@TriTexan @SpaceX Yes”

“Preparing to fire the Starship Raptor engine at @SpaceX Texas https://t.co/8JCOi1BG6z”

“SpaceX documentary actual footage https://t.co/RrEwYwMNgj”

“@JasonHouge @SpaceX @boringcompany These are industrial strength. Not recommended for use at home!”

“Testing metallic heat shield at 1100C (2000F) @SpaceX https://t.co/frP5eZ5a0z”

“@WevolverApp @SpaceX Dragon 2 was originally designed to land with thrusters, but it’s not the right architecture for heavy transport to the moon or Mars, so we decided not to qualify it for thruster landings”

“@musicnick1985 @Teslarati Teslarati is very thoughtful & well-written, but this stems from a miscommunication by SpaceX”

“@nextspaceflight @Teslarati The LA Times has a long track of unreasonable attacks on SpaceX & Tesla, but in this case it was our miscommunication”

“SpaceX Dragon from as seen from @Space_Station viewport https://t.co/WE82irbsmp”

“View of SpaceX Dragon 1 berthed with @Space_Station in the last Cupola opening. Dragon 2 (Crew Dragon) launching soon.”

“@Sloppy93 @SpaceX Body/tank diameter is 9m or about 30ft”

“Starship test flight rocket just finished assembly at the @SpaceX Texas launch site. This is an actual picture, not a rendering. https://t.co/k1HkueoXaz”

“@MKBHD I’m not. Will use SpaceX cold gas thruster system with ultra high pressure air in a composite over-wrapped pressure vessel in place of the 2 rear seats.”

“@FrameshiftShark @SpaceX More on this in a few months”

“@LPAmdee @SpaceX Aiming for 4 weeks, which probably means 8 weeks, due to unforeseen issues”

“Good shot of @SpaceX Starship flight test vehicle being assembled in Boca Chica, Texas”

“@Robotbeat @Jon128123 @Diver2441 @Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @alan1bernard SpaceX metallurgy team developed SX500 superalloy for 12000 psi, hot oxygen-rich gas. It was hard. Almost any metal turns into a flare in those conditions.”

“Honored to work with amazing teams at SpaceX & Tesla!”

“@realrobcopeland @SpaceX Totally false. Buried in this incredibly misleading WSJ article is the actual statement from Thiel’s Founder’s Fund: “we have no concerns whatsoever.””

“@RenataKonkoly @SpaceX Machete!!”

“@Dragonmaurizio We may use it for an internal SpaceX mission”

“@dxk_ @ZainRaz4 @Erdayastronaut @SpaceX Three things, one of which is CH4”

“@PicklePunchD @Erdayastronaut @SpaceX No”

“@ZainRaz4 @Erdayastronaut @SpaceX No”

“@Erdayastronaut @SpaceX Reentry scorchmarks, not simple soot. Can’t wipe it off.”
