“@spacex360 If lobbying & lawyers could get u to orbit, Bezos would be on Pluto rn”

“@spacex360 Exactly”

“@wapodavenport However, even if it were 16 flights with docking, this is not a problem. SpaceX did more than 16 orbital flights in first half of 2021 & has docked with Station (much harder than docking with our own ship) over 20 times.”

“@wapodavenport 16 flights is extremely unlikely. Starship payload to orbit is ~150 tons , so max of 8 to fill 1200 ton tanks of lunar Starship. Without flaps & heat shield, Starship is much lighter. Lunar landing legs don’t add much (1/6 gravity). May only need 1/2 full, ie 4 tanker flights.”

“@lrocket @thesheetztweetz Yeah”

“@thesheetztweetz SpaceX could do it if need be”

“@ErcXspace @SpaceX @Erdayastronaut 🔥🔥”

“@DanaEn803 @Dr_ThomasZ @thesheetztweetz @SpaceX Sure”

“@Kristennetten @SpaceX It will be exciting to see what new cultures humanity creates on other heavenly bodies!”

“@Dr_ThomasZ @thesheetztweetz @SpaceX Due to its size & ability to return science instruments even from deep space, Starship will enable a whole new class of science missions”

“@WholeMarsBlog @NASASpaceflight @BBCAmos There is a reason no fully reusable orbital rocket has been built – it’s an insanely hard problem. Moreover, it must be rapidly & completely reusable (like an airplane). This is the only way to make life multiplanetary. Efficiencies of scale is why Starship is so large.”

“@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”

“@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 4 significant items: - Final heat shield tiles for ship - Thermal protection of booster engines - Ground propellant storage tanks - QD arm for ship 2 weeks.”

“@jrosinski97 @SpaceX Absolutely”

“Starship Fully Stacked https://t.co/Fs88RNsmfH”

“@austinbarnard45 Total coincidence! Also, booster height was originally 70m, but we eliminated a half barrel for manufacturing efficiency, so now it’s …”

“Aiming to stack ship on booster today https://t.co/67ehWTI57v”

“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”

“@PPathole Mars looks amazing”

“@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.”

“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.”

“@RenataKonkoly @JonErlichman I was asked by a reporter if I was optimistic or pessimistic about SpaceX’s future. That was my answer.”

“Installing Starship booster engines for first orbital flight https://t.co/yhqrNFBclh”

“@NASASpaceflight Needs to be level & match booster fittings. We will find out on ~Tuesday.”

“@DavidNagySFgang @rocketry_catboy Indeed. Grid fin designs clearly work, but do they maximize payload? Good chance that they do not. Something with much more drag to reduce terminal velocity & so reduce landing propellant might have better performance. Not sure. Potential future optimization.”

“@WholeMarsBlog The Tesla AI predictions are swiftly becoming superhuman – its guesses for what it can’t see well feel like ESP. It has a vastly larger training set than any human & thinks only about driving.”

“@WholeMarsBlog There is always a lot of cleanup after a major code release. Beta 9.2 will be tight. Still some fundamentals to solve for Beta 10, but now that we’re pure vision, progress is much faster. Radar was holding us back.”

“@nextspaceflight Stage Zero, which is everything needed to launch & catch the rocket, is at least as hard as the booster or ship”

“@WDWSpeakers @WholeMarsBlog PC desktop with latest graphics card, although I have a Mac too. Gigabyte laptop.”

“@Erdayastronaut @SpaceX Hadn’t showered in several days. We are going hardcore with Starbase Surge.”

“@JeffTutorials @WholeMarsBlog That’s arguably a security issue, but allowing companies to use other payment options, especially for in-app purchases would be fair. As soon as they allowed that, they would have to lower their fees. As for the cost of reviewing apps for security, a fixed fee makes sense.”

“@WholeMarsBlog Normally, competitive pressure would force Apple to lower fees, but Apple & Android have a duopoly on phones. When interface familiarity is taken into account, it’s basically a monopoly. The effective 30% sales tax Apple charges is hidden from users or there would be an outcry.”

“@RenataKonkoly @WholeMarsBlog Top feature request for sure”

“@WholeMarsBlog Actually, I like & use Apple products. They are just obviously overcharging with App Store. I mean 30% fees for doing almost zero incremental work is completely unreasonable. Epic wouldn’t bother processing their own payments if App Store fees were fair.”

“@spacex360 GAO 💪”

“@WholeMarsBlog A lot”

“@WholeMarsBlog This should be clear to anyone who has experienced the FSD beta evolution. Self-driving requires solving a major part of real-world AI, so it’s an insanely hard problem, but Tesla is getting it done. AI Day will be great.”

“@RationalEtienne @thesheetztweetz @BryceSpaceTech @SpaceX @roscosmos @Arianespace @ArianeGroup @northropgrumman @RocketLab @ulalaunch @VirginOrbit @torybruno Mass to orbit is the fundamental metric for making life multiplanetary”

“@thesheetztweetz @BryceSpaceTech @SpaceX @roscosmos @Arianespace @ArianeGroup @northropgrumman @RocketLab @ulalaunch @VirginOrbit @torybruno Upmass is what matters. One Starship will lift what all Falcons did in Q2 on a single flight.”

“@Jaydev_Chauhan_ Yeah, SpaceX team is cranking hard!”
