@brian_armstrong @MarkWarner Agreed, this is not the time to pick technology winners or losers in cryptocurrency technology. There is no crisis that compels hasty legislation.

@teslaownersSV Long time

An honor to work with such a great team

@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.

@BBCAmos @NASASpaceflight Ok

@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 …
