“@Erdayastronaut @NASASpaceflight @BocaChicaGal @TheFavoritist The ship rings are thicker than they need to be (for now), so same thickness works for booster & ship for hoop stress. Booster lower tank will have longitudinal stiffeners to prevent buckling.”

“@Zshauladventure @NASAKennedy @ulalaunch @SpaceX @NatReconOfc Good to see. Inspiring for future of space!”
“@ErcXspace @SpaceX @FelixSchlang @MarcusHouseGame @Erdayastronaut @NASASpaceflight Great render! The circumferential welds & skin panels will be much smoother in future builds.”
“@austinbarnard45 Weld esthetics will improve greatly in upcoming Starships”
“@RationalEtienne @WholeMarsBlog Yes”
“@vm_one1 @waEMD @SpaceX We will probably IPO Starlink, but only several years in the future when revenue growth is smooth & predictable. Public market does *not* like erratic cash flow haha. I’m a huge fan of small retail investors. Will make sure they get top priority. You can hold me to it.”
“@PerezShivam @waEMD @SpaceX Fate loooves irony haha”
“@waEMD @SpaceX Glad SpaceX could help! We are prioritizing emergency responders & locations with no Internet connectivity at all.”
“@WholeMarsBlog Suppliers. We’re only doing high energy nickel ourselves, at least for now. Also, maybe the presentation wasn’t clear that we’ve actually had our cells in packs driving cars for several months. Prototypes are trivial, volume production is hard.”
“Starship SN8 with rear body flaps https://t.co/GdxMbzX0ct”
“@hisdirtremoves @SpaceX Not bad”
“@xiang_aw @WholeMarsBlog This does seem like the opposite of open. OpenAI is essentially captured by Microsoft.”
“@WholeMarsBlog Haha true”
“@Neopork85 @SpaceX Haha”
“@ICannot_Enough @WholeMarsBlog We will be a little below that this year (most challenging year we’ve ever had), but probably above that next few years”
“@WholeMarsBlog That’s about right. Maybe a little faster.”
“@Neopork85 @SpaceX @MarcusHouseGame We really need better legs for Starship. They’re coming.”
“@Neopork85 @SpaceX @MarcusHouseGame Most likely, all flaps will fold after landing to reduce wind tip over force. There may be some cases where flaps deployed help stability (change in wind direction), in which case one or more flaps will extend.”
“@WholeMarsBlog Yes”
“@WholeMarsBlog There’ll be lots of green space around factory, but building itself is continuous. The “open” areas inside are covered. They’re internal semi truck roads inside a giant monolithic building.”
“@Model3Owners @TrungTPhan It took an utterly insane amount of work to move the SpaceX & Tesla success probabilities above ~zero”
“@TrungTPhan To be frank, in the early days, I thought there was >90% chance that both SpaceX & Tesla would be worth $0. The press & aerospace / automotive industry at the time (correctly) agreed with me.”
“@MatthewCable6 @ErcXspace Just a guess, but probably mid teens. Booster & stacking on orbital pad are likely limiting factors. We’ll build several ships just to improve the production system.”
“@PPathole @_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX Cumulative mass to orbit per year (corrected for GTO & other high energy orbits) is the best comparative metric imo”
“@PPathole @_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX That’s the number that really matters”
“@_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX Anyone tracking tonnage to orbit per year for all launch vehicles?”
“SN8 Starship with flaps & nosecone should be done in about a week. Then static fire, checkouts, static fire, fly to 60,000 ft & back.”
“@WhatsupFranks @samiralyateem @WholeMarsBlog Exactly. Problems like that have been addressed.”
“@PPathole @WholeMarsBlog Yes. Good insight.”
“@samiralyateem @WholeMarsBlog All frames stitched to single frame (tricky, as all cameras overlap in different ways) & then creating video segments for labeling & training. Everything from the labeling tools themselves to training to inference had to be rewritten.”
“@WhatsupFranks @brandonbernicky @WholeMarsBlog Much”
“@flcnhvy @WholeMarsBlog Yes”
“@brandonbernicky @WholeMarsBlog Releasing private beta in 2 to 4 weeks, public beta (early access owners who opt in) 4 to 6 weeks after that, then all US Tesla owners mid December. Above schedule is contingent upon not encountering major unexpected setbacks.”
“@WholeMarsBlog And this still isn’t using the dramatically better “4D” (aka simultaneous surround video from 8 cameras) architecture”
“@Astra Sorry to hear that. I’m sure you’ll figure it out though. Took us four launches to reach orbit. Rockets are hard.”
“@Erdayastronaut @PPathole @SpaceX We’re pretty close to the manufacturing size limit for a milled copper & steel jacket nozzle. Lot of complexity to add a nozzle extension to a sea level engine for small gain. Also hard to fit bigger engine nozzles on the booster.”
“@Erdayastronaut @PPathole @SpaceX Above 50% likely to make it”
“@PPathole @SpaceX This is a test engine. Flight articles are fixed with no gimbal.”
“@SpaceX Worth noting that thrust is only slightly higher with the big bell nozzle version. Larger bell is primarily for efficiency in vacuum. Aiming for 380+ sec Isp for RVac long-term. Initially likely to be ~372.”
“@austinbarnard45 Starship SN6 flew asimilar hop to SN5, but it was a much smoother & faster operation”
“@SpceEnthusiast @tjmurphy_mit @thesheetztweetz @ExploreMars @SpaceX @TheeSpaceDude Over time, outer 20 will have ~300 tons of thrust & inner 8 ~210, so roughly 7500 tons total at sea level or 1.5 T/W for booster+ship”
“@SpceEnthusiast @tjmurphy_mit @thesheetztweetz @ExploreMars @SpaceX @TheeSpaceDude Yeah”
“@tlowdon @EthicalSkeptic Antibody half-life for cov2 is very short. In a study that SpaceX did working with Harvard epidemiology, it appears to be as low as 2 or 3 weeks. Nonetheless, reinfection rates are very low & symptoms are minor, perhaps due to memory T cells https://t.co/z9WlvIjoTw https://en.m.wikipedia.org/wiki/Memory_T_cell”
“@WholeMarsBlog @MarcusHouseGame @Neopork85 @SpaceX @Erdayastronaut @SpaceToday1 @ElonsWorld @FelixSchlang @ChrisG_NSF @DJSnM Not yet”
“@MarcusHouseGame @Neopork85 @SpaceX @Erdayastronaut @SpaceToday1 @ElonsWorld @FelixSchlang @ChrisG_NSF @DJSnM Yes. This is the hardest part of the booster design.”
“@biogirl09 @JaneidyEve @Tesmanian_com @SpaceX We can’t have a blanket pass, but maybe for some events”
“@flcnhvy @DJSnM Neuralink this month & Tesla next month, SpaceX probably October. We will have made a lot of progress by then. Might have a prototype booster hop done by then.”
“@WholeMarsBlog We were too obtuse for our own good, although I think it works esthetically. Those are folded-over current collectors at the top/bottom of the cell, which are important, but I don’t want to jump the gun on Sept 22 …”
“@PPathole @Erdayastronaut @dauqhx @universal_sci Mars is easier than the moon for propellant production. Could get going with only one ship, where the ship itself is the propellant plant. Needs to make ~2 tons/day.”
“@Erdayastronaut @dauqhx @universal_sci Starship propellant is ~78% oxygen, so an O2 plant on the moon would be enough. Otherwise, we could brute-force it with tankers to low Earth orbit. That’s probably faster.”
