“@BillyM2k The only thing keeping the other orbital rocket programs alive is government protection or they’d be deader than a doornail and everyone knows it. But oh well … comme ci, comme ça.”

“@Astro_Elliott @Teslarati @ResidentSponge Aiming to have hot gas thrusters on booster for first orbital flight”

“@rustyrockets @bariweiss @shellenberger @mtaibbi 💯”

“@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.”

“@NASASpaceflight Hopefully first try with booster 5”

“@NASASpaceflight It will look crazy tall with booster & fairing at 122m / 394 ft”

“@MarcusHouse It will have high pressure air rocket thrusters behind a license plate that flips down. Bong, James Bong …”

“@arstechnica @SciGuySpace Russia has great rocket technology & talent. Much respect. Would encourage focus on reusability. Single-use rockets cannot be competitive any more than single-use aircraft.”

“My favorite shot from the last rocket landing attempt on the droneship http://t.co/8a403c7Fv1”

“@lexfridman In theory, it saves landing leg mass & enables immediate reflight of an otherwise unwieldy, giant rocket”

“@Astra Sorry to hear that. I’m sure you’ll figure it out though. Took us four launches to reach orbit. Rockets are hard.”

“@ID_AA_Carmack Thanks John, really admire you too! I think you’re one of the best engineers ever. Hope you return to working on rockets one day.”

“@Erdayastronaut By “volume production”, I mean 2 to 4 engines per day. That’s super high volume for big rocket engines, but low volume by automotive standards.”

“@arstechnica @SciGuySpace They are aiming too low. Only rockets that are fully & rapidly reusable will be competitive. Everything else will seem like a cloth biplane in the age of jets.”

“RT @MarioNawfal: 🇨🇦 CANADA’S IMMIGRATION GRAPH JUST TURNED INTO A ROCKET SHIP Canada's bringing in 2.5 million people by 2025. It's the b…”

“@lrocket What propellant?”

“@DavidNagySFgang Booster engines are not shrouded by skirt extension, as with ship. Engines extend about 3m below booster.”

“RT @cb_doge: ELON MUSK: "I'm a technologist. I build rockets and cars. I derive joy from seeing people enjoy the products that my companies…”

“@Rainmaker1973 Used a lot in rocketry”

“Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion. Prob ok, but some risk of tipping.”

“RT @latestinspace: “A rocket will never be able to leave the Earth’s atmosphere.” - New York Times, 1936 https://t.co/85HT04BS4N”

“@teslaownersSV @iamyesyouareno @MarioNawfal The specific area I’m talking about is engineering, which is needed to build the best technology. Encouraging kids to learn how things work is the key. Take apart car engines, toasters, microwave ovens, speakers, etc. Make model airplanes, rockets, cars. As you’re doing this…”

“RT @teslaownersSV: “I cannot be President, and I actually don't want to be President. So, to be clear, I want to build rockets and cars.”…”

“RT @cb_doge: "We should send rockets not at each other, but rather to the stars." 一 Elon Musk https://t.co/GUFdqgXR6m”

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

“@lrocket @SpaceAbhi Gwynne and I didn’t tell the company, as it would have been demoralizing”

“Currently looking good for a Sunday night (~8pm local) attempted orbital launch and rocket landing at Cape Canaveral”

“@nextspaceflight Payload reduction due to reusability of booster & fairing is <40% for F9 & recovery & refurb is <10%, so you’re roughly even with 2 flights, definitely ahead with 3”

“@newscientist This is actually a good thing btw. China is making amazing progress in space, rapidly iterating on rocket & space station technology. Great respect.”

“@Bob_Richards One rocket, slightly toasted”

“@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.”

“Max recovered booster velocity was Mach 7.9 (BulgarianSat). Energy is velocity squared, so this is a bigger difference than it appears”

“@cb_doge More than twice the power of the Saturn V Moon rocket. Next version will be 3X.”

“@EvaFoxU @BillyM2k I’m a dirty rocket”

“@rustyrockets @JDVance 💯”

“@danpiemont Thank you for the thoughtful rebuttal. To the best of my knowledge, none of the rideshare missions have lost money. I do hope that rocket companies focus on reusability. That is the fundamental breakthrough needed for humanity to become a spacefaring civilization. Falcon is…”

“@TheBabylonBee He will rocket straight to the top!”

“Rocket reentry is a lot faster and hotter than last time, so odds of making it are maybe even, but we should learn a lot either way”

“@MarcusHouse @artzius Current plan is to increase base Raptor thrust to ~230 tons or ~500 million lbs & increase booster engine count to 32 or 33”

“@thejackbeyer @NASASpaceflight @BocaChicaGal @NicAnsuini Our focus is on reliability upgrades for flight on Booster 7 and completing Booster 9, which has many design changes, especially for full engine RUD isolation.”

“@CSI_Starbase Agreed, we recently made this change & many others. An intense effort is underway to achieve robust engine containment in case of RUD to protect booster, other engines & launch ring.”

“@thesheetztweetz Full & rapid reusability is the holy grail of orbital rocketry”

“@archillect Sorry, probably going to be a lot of rocket pics from @archillect 🤣🤣”

“@Erdayastronaut @rweb11742 The most amazing thing about rocket engines is that they *sometimes* don’t blow up! The amount of power going through them boggles the mind.”

“@Teslarati No matter what, we need to pressurize the production system. Rocket design is relatively easy, making one is hard, making many is extremely hard. Manufacturing is underrated.”

“Most recent rocket took max damage, due to v high entry velocity. Will be our life leader for ground tests to confirm others are good.”

“@lrocket @thesheetztweetz Yeah”

“@Erdayastronaut We’ve already done a lot of iteration on ship. For rapid reusability, booster must return to launchpad, so inert mass impacts ascent, boostback & landing burns. Triple whammy. Also, booster flight rate is ~5X that of ship, so multiple mass $ cost by 5.”

“@PPathole @Rainmaker1973 The amazing part will be having an orbital rocket that is fully & rapidly reusable with any payload at all! Everyone else gave up when they realized that their fully reusable payload<0. We still have a long way to go.”

“@MrManderly @mysteriouskat @Independent @rustyrockets Good point. Politicians & political parties should be supported on their merits, not like they are one’s favorite sports team.”
