“@OranMaliphant @Erdayastronaut Could do it, but we developed low cost reusable tiles that are much lighter than transpiration cooling & quite robust”

“@Erdayastronaut Better just to ride your max temp all the way down & let T^4 be your friend. Lower atmosphere cools you down real fast, so not crazy hot after landing.”

“@DJSnM Exactly. For reusable heatshield, minimize peak heating. For ablative/expendable, minimize total heat. Therefore reusable like Starship wants lift during high Mach reentry for lower peak, but higher total heat.”

“@Erdayastronaut It does actually generate lift in hypersonic regime, which is important to limit peak heating”

“@flcnhvy @Erdayastronaut Many powerful electric motors & batteries. Force required is enormous, as entire fin moves. More about this on the 28th.”

“@Erdayastronaut That’s correct. Essentially controlled falling, like a skydiver.”

“@bopinion Herbert Diess is doing more than any big carmaker to go electric. The good of the world should come first. For what it’s worth, he has my support.”

“@JaneidyEve Just sent a note to check”

“Some secrets are too dangerous to be free https://t.co/g547UdmiJ7”

“@TheOnion “Between the trees and the forest floor, it’s like a giant mural,” continued the veritable High Priest of the Harvest Season, adding that he would soon have to rake his driveway, an activity for which he will most certainly don a cashmere scarf.”

“@Mich41V4294 @flcnhvy @28delayslater @karpathy Hoping to open in Slovakia, Croatia, Serbia & most of Eastern Europe early next year. Finally, we will do Nikola Tesla proud by having his cars in his countries of origin!”

“@TeslaMiles @28delayslater @karpathy @Tesla OG Roadster is def helping us out here with 826M miles by itself https://t.co/Pcybhf8jc3 https://www.whereisroadster.com”

“@flcnhvy @28delayslater @karpathy Ahem … well … um …”

“@28delayslater @karpathy Classified as a URO, unidentified road object (from Area 69)”

“@Kristennetten SpaceX Foundry is used exclusively for advanced alloys/shapes for Raptor, incl our superalloy, SX500”

“Bottom half of Starship at night. Top half with forward fins & header tanks probably stacks on Wednesday. Three Raptors already installed. https://t.co/haq3m1V1Wm”

“Raceway & flap hinge aero covers”

“Just leaving SpaceX Starship build site in Boca https://t.co/Bqt40mSdX4”

“@Erdayastronaut @CptnCrutch5373 @Kalzsom Super Heavy rocket will be much like Falcon 9, but the Ship is a strange combination of Dragon, F9 & a skydiver.”

“@happych19952208 😉”

“@CptnCrutch5373 @Erdayastronaut @Kalzsom Approximately correct. We also fire the ACS thrusters to rotate the vehicle & ignite Raptors at full gimbal angle to complete the turn.”

“@Kalzsom @Erdayastronaut For aero control, it comes down to % of cross-sectional area moving vs not. Flexible as to whether front or rear, so long as within bounds of center of mass & pressure.”

“@Erdayastronaut Current analysis, which I’m not fully bought into, suggests that 2 rear fins with separate airframe-mounted legs will be lighter, so this is the plan for Mk1/Mk2”

“@Erdayastronaut Stability is controlled by (very) rapid movement of rear & fwd fins during entry & landing, as well as ACS thrusters. The smaller leeward “fin” would simply be used as a leg.”

“@Erdayastronaut Stability is not an issue with 3”

“@SpaceXFan97 Nose tip has forward movable fins, cold gas attitude control thrusters, header tanks for landing, composite pressure vessels, several large batteries, etc. Placed up there to balance high mass of Raptors & rear fins at the bottom.”

“@SpaceXFan97 Yes. There’s a huge amount of hardware in the tip of the faring that being integrated on the ground, which is why we haven’t closed it out.”

“Adding the rear moving fins to Starship Mk1 in Boca Chica, Texas https://t.co/HWLihqihph”

“@teslaownersSV Thanks!”

“Either way, sustainable energy wins!!”

“@cleantechnica srsly”

“@vincent13031925 @ResidentSponge @Teslarati It’s my 🔥 glasses 😉”

“@Robotbeat @justpaulinelol @Teslarati Sure. Have to do it on Mars from beginning. Will ultimately do that on Earth too, so rocket flights will be zero net carbon long-term.”

“@TeslaTested @Teslarati Next quarter”

“@TeslaTested @Teslarati Will discuss with my product team next week, but probably”

“@justpaulinelol @Teslarati Yes”

“@Teslarati Great work by SpaceX parachute engineering! The Crew Dragon parachutes are way more difficult than they may seem. The Apollo program found them to be so hard that it became a notable morale problem!”

“@tdenton1138 @sciam @GretaThunberg A 16 year old who has better reasoning & more heart than the vast majority of political leaders”

“@flcnhvy @nytimes That’s what life was like back in 1985”

“@nytimes You have been warned https://t.co/11CHFHUdr1”

“@itsJayLew @tesletter @tesla_truth No, it’s one integrated release”

“@tesletter @tesla_truth Fixing several minor bugs & a regression in highway driving, so probably early to mid next week”

“@chrisleehawaii @Tesla Much better chess engine coming”

“@tesla_truth Well said”

“@MercedesBenz Very meaningful action by the company that invented the internal combustion engine. People will remember this day. Respect.”

“Electric is the future! Congratulations Daimler!!”

“@EvaFoxU @MemesOfMars @fermatslibrary Nice compression”

“@MemesOfMars @fermatslibrary And of course, this one, but that’s obv https://t.co/UKWYrBwjkZ”

“@MemesOfMars @fermatslibrary e^👁🥧 + 1 = 0”

“@fermatslibrary For some reason, I always loved this formula”
