“@WholeMarsBlog @NASASpaceflight @BBCAmos Higher structural margins overall are needed for reuse, plus: Booster - Grid fins for aero control - Boostback & landing propellant tanks - Protecting engines from entry loads Ship - Body flaps for aero control - Deorbit & landing propellant tanks - Heat shield”

“@Astro_Elliott @NASASpaceflight @BBCAmos Inevitably”
“@NASASpaceflight @BBCAmos Over time, we might get orbital payload up to ~150 tons with full reusabity. If Starship then launched as an expendable, payload would be ~250 tons. What isn’t obvious from this chart is that Starship/Super Heavy is much denser than Saturn V.”
“@thesheetztweetz It is ~98% done, but the remaining tiles are unique shapes requiring machining”
“@thesheetztweetz 4 significant items: - Final heat shield tiles for ship - Thermal protection of booster engines - Ground propellant storage tanks - QD arm for ship 2 weeks.”
“@thesheetztweetz Dream come true”
“@jrosinski97 @SpaceX Absolutely”
“Starship Fully Stacked https://t.co/Fs88RNsmfH”
“@NASASpaceflight 🤍 🖤”
“@IvanEscobosa @ajtourville @Tesla Probably”
“@ajtourville @Tesla Tesla Automation (Deutschland) built a specialized machine to wrap the rotor with carbon fiber at precise tension. If too low, it would come loose at low temp, due to CTE differences. If too high, it would snap at high temp & rpm.”
“@austinbarnard45 Total coincidence! Also, booster height was originally 70m, but we eliminated a half barrel for manufacturing efficiency, so now it’s …”
“@jack DMTwitter”
“@ChrisDungeon Reality is total opposite of what detractors say! Biggest challenge is recruiting enough people to build cars. SF Bay Area essentially has negative unemployment, so people at our factory have several other job offers. If they weren’t treated well, they would leave immediately!”
“@techvamp Once Mechazilla is operational, winds will rarely be an issue”
“@b280c_2 👍”
“Winds are too high today. Looks like wind speed will be low enough to stack early tomorrow morning.”
“@NicAnsuini Remaining tiles are on their way!”
“@arctechinc @POTUS Irony indeed”
“Aiming to stack ship on booster today https://t.co/67ehWTI57v”
“@SquawkCNBC @SecretaryPete https://t.co/51BrgAaotS”
“@ID_AA_Carmack It would be an honor to have you visit Starbase”
“@cleantechnica Yeah, seems odd that Tesla wasn’t invited”
“@teslaownersSV @WalterIsaacson He’s shadowed me for several days so far”
“@WorldAndScience Makes sense”
“@28delayslater 🤣”
“@lexfridman @WalterIsaacson Yeah, they’re all good, but I particularly liked his biography of Ben Franklin”
“@andrewjwells @WalterIsaacson 🤣🤣”
“@josh_bickett @WalterIsaacson Maybe one day”
“If you’re curious about Tesla, SpaceX & my general goings on, @WalterIsaacson is writing a biography”
“@ID_AA_Carmack I have great admiration for John’s engineering ability! What he did with Armadillo was incredible. I’ve tried to convince him many times to join SpaceX, but he has always declined (sigh).”
“Mechazilla will do this for future rockets, but it’s not quite ready yet”
“Moving rocket to orbital launch pad https://t.co/zZLiXIPD6M”
“@AustinTeslaClub That is the goal. Our official name is actually Space Exploration Technologies. SpaceX is short form.”
“@aparanjape @Erdayastronaut @SpaceX I do think that great design & engineering of products are critical, but manufacturing & supply chain require orders of magnitude more work”
“All 6 engines mounted to first orbital Starship https://t.co/l5QnQRSg3D”
“@teslaownersSV @NASA I thought we had lost for sure. We were just a tiny company back then, only 1 of 4 launches got to orbit & I had no money left. Out of the blue, a few days before Christmas, NASA calls to say we won.”
“@teslaownersSV @NASA Just want to say thanks to those in government who fight hard for the right thing to happen, despite extreme pressure to do otherwise. Therein lies the core goodness of the American state.”
“@teslaownersSV @NASA I do love NASA, always have”
“@teslaownersSV @NASA It’s true”
“@PPathole Mars looks amazing”
“@Erdayastronaut @ErcXspace We stole the idea from Karate Kid”
“@flcnhvy Pitch control requires more force than yaw & much more force than roll. Also, grid fins closer to or in the wake of the booster are less effective. However, pretty good aero control can technically be achieved with only 2 grid fins, with some effect on accuracy.”
“@TeslaFruit Thanks Sandy!”
“Super Heavy Booster moving to orbital launch mount https://t.co/axaDnXNm84”
“@ErcXspace Very close to real! Arms are able to move during descent to match exact booster position. Catch point is off to side, in case catch fails – don’t want to hit launch mount. Booster is transferred back to launch mount for next flight. Designed to have <1 hour turnaround.”
“@stem_feed That’s about right. Civilization can be powered with a very small % of Earth having solar panels.”
“@RenataKonkoly @JonErlichman I was asked by a reporter if I was optimistic or pessimistic about SpaceX’s future. That was my answer.”
“@JonErlichman 2008 was an extremely tough year on every level”
“@tesla4k @MatanMazursky It was difficult”
