“@tobyliiiiiiiiii @SpaceX @NASA @NASA_LSP @NASAJPL @esa Actually, off to the side (so it doesn’t take out the launch mount in bad landing), but with the same arm used to pick up the ship”

“@tobyliiiiiiiiii @SpaceX @NASA @NASA_LSP @NASAJPL @esa Where it should be!”

“@mirojurcevic @TashaARK This is a misperception. SpaceX developed & continues to use lidar for Dragon docking with @Space_Station. Just pointless imo for self-driving. If you’re going to do active photon generation, use an occlusion penetrating wavelength, like precision radar at ~4mm.”

“@PhilippeCROIZON @SpaceX One day we will fly you on Starship”

“@hisdirtremoves @SpaceX I can’t comment on turbopump internal details, but you’re roughly in the ballpark. Wow, rocket turbopumps, especially if oxygen-rich, are insanely hard! Arguably, the hardest mechanical/fluids/combustion problem known to exist.”

“@RocketLab Congrats!”

“@westcoastbill @SpaceX 13 years & $11 billion … wow”

“@peterrhague It’s designed to make life multiplanetary, otherwise extreme overkill for mere Earth sector activity! Starship fleet mass to orbit per year will be more than 1000 times all current Earth rockets combined, including Falcon. Necessary, for a city on Mars.”

“@Erdayastronaut @rweb11742 Merlin is a strong local maximum design, but kerosene is suboptimal fuel, no matter what you do. What matters is cost per ton to Mars. CH4 is the only choice imo. Important: O2/CH4 allows OF ratio of ~3.5 vs ~2.5 for kerosene, so ~78% of propellant is oxygen.”

“@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.”

“@DJSnM @Erdayastronaut @CharlesNOtrumps @rweb11742 Absolutely. Production/testing of rocket engines is over 90% of the problem. This is true in general. For cars, production is over 99% of the problem. That 1% inspiration is very important, but it’s less than 1% of the pain.”

“Dragon can also hover & land propulsively, but we use the parachutes for maximum safety https://t.co/Mr7VFIQwWf https://m.youtube.com/watch?v=07Pm8ZY0XJI”

“4 Astronauts fly to @Space_Station on Sat night from Cape. First operational flight of Crew Dragon. https://t.co/uZCGiKciKb”

“@DJSnM @DavidHuber15 @nickhenning3d @SpaceX @ErcXspace @Neopork85 @C_Bass3d @Caspar_Stanley @SpacexVision @FelixSchlang Probably”

“@nickhenning3d @SpaceX @ErcXspace @Neopork85 @C_Bass3d @Caspar_Stanley @SpacexVision @FelixSchlang There’s no entry/braking burn & hypersonic angle of attack is ~70 degrees”

“@Erdayastronaut @RenataKonkoly @SpaceNews_Inc Am hoping to change booster design to land back on launch mount with no legs. Will require extreme precision.”

“@SpaceNews_Inc China understands the profound importance of reusability. The era of expendable rockets will soon be over.”

“@LinusTech @SpaceXStarlink @SpaceX 🇨🇦 😀”

“@LinusTech @SpaceXStarlink @SpaceX Awaiting approval from Canadian authorities”

“@ICannot_Enough @ZainRaz4 @vincent13031925 @JonErlichman Yes, although I didn’t expect the stock to rise so much so soon. The reason for the stock options is that they’re needed to help pay for humanity to get to Mars in 10 to 20 years.”

“@PPathole Lowering Starlink terminal cost, which may sound rather pedestrian, is actually our most difficult technical challenge”

“Several thousand more Starlink beta participation invitations going out this week”

“@WholeMarsBlog @steezyysosa @AustinTeslaClub @JoeTegtmeyer @peterdog15 @TXTerafactory @Terafactorytx @lqdchkn @jd_average @EliBurton_ Sure, maybe in a month or so”

“@WholeMarsBlog Accurate”

“@WholeMarsBlog 💫 🛰”

“Congratulations SpaceX Team!”

“@Erdayastronaut @tobyliiiiiiiiii @austinbarnard45 @SuperclusterHQ I’m in Boca every week, so maybe we could talk then. Given that Starship is not exactly subtle, this is more of a design clarification to match what people can already see.”

“@tobyliiiiiiiiii @austinbarnard45 @SuperclusterHQ Good point. Probably next week in form of a written piece on SpaceX website.”

“@austinbarnard45 @SuperclusterHQ Great pics! That we now have the beginnings of a Starship production system is most meaningful.”

“@WholeMarsBlog Yup. With beta updates, there’ll be a lot of 2 steps fwd, 1 step back situations, but pace of improvement will be extremely fast.”

“@SpacePadreIsle Starship is coming together!”

“@SpaceX Just a small-seeming issue with loss of upper stage camera. Probably nothing serious, but standing down to re-examine whole vehicle just in case.”

“@WholeMarsBlog Not intentional! We just wanted to show that you could theoretically convert the entire US vehicle fleet to electric using only the lithium in Nevada, a single state. Tesla will do lithium mining only as needed. We also found a way to extract lithium using NaCl (table salt).”

“Starship nosecone, high bay & tiki bar https://t.co/9qXYxMMIUj”

“Data from 3 engine Starship static fire this morning looks good. Proceeding with nosecone mate.”

“@bamtheteslaman1 @cleantechnica Doesn’t seem to be any life in this solar system. Maybe under the ice of Europa or extremophile bacteria below the surface of Mars. Worth reading: https://t.co/ym0d53HgyS https://en.m.wikipedia.org/wiki/Drake_equation”

“@Neopork85 @SpaceX @NASASpaceflight @austinbarnard45 @whoisheartbreak @Erdayastronaut @FelixSchlang @MarcusHouseGame @SpaceToday1 More great renderings! Significant improvements coming to the welds.”

“Will be less roomy with 3 vacuum rocket engines added https://t.co/pKtDFdiZYC”

“@flcnhvy @WholeMarsBlog @Kristennetten @boringcompany @Tesla It’s still there, but focus is Vegas & Prufrock, our new tunneling machine”

“@WholeMarsBlog @Kristennetten @boringcompany @Tesla Maybe a month or so. Some finishing touches need to be done on the stations.”

“@bad_at_life @WholeMarsBlog Diess is doing his best to move in the right direction, but he’s in a tough position with so many constituencies to please. No way to make everyone happy.”

“@flcnhvy Good grief! SpaceX is getting zero money for this. Starship is designed to carry people & cargo around Earth (also to moon & Mars). Vast majority of use will be civilian. It’s just like an airline in space. All airlines sometimes carry military cargo, but ~99% is civilian.”

“@Erdayastronaut @flcnhvy @PelleBrannvall @Neopork85 @Caspar_Stanley @ErcXspace @MarcusHouseGame @FelixSchlang @C_Bass3d @nickhenning3d @SpaceX @BocaChicaGal SpaceX/Tesla metallurgy & new materials team is next-level”

“@Erdayastronaut @PelleBrannvall @flcnhvy @Neopork85 @Caspar_Stanley @ErcXspace @MarcusHouseGame @FelixSchlang @C_Bass3d @nickhenning3d @SpaceX There are sensitive elements, but they’re on the inside. Also, a good telephoto lens will be able to capture what I’ve posted. And yeah, anyone who can reverse engineer what I’ve posted doesn’t need to reverse engineer!”

“@Teslarati Great work by SpaceX valve engineering & production!”

“@flcnhvy @Neopork85 @Caspar_Stanley @ErcXspace @MarcusHouseGame @FelixSchlang @C_Bass3d @nickhenning3d @SpaceX It might be used in some areas. ITAR laws prevent us from being too specific about solutions.”

“@Neopork85 @Caspar_Stanley @ErcXspace @MarcusHouseGame @FelixSchlang @C_Bass3d @nickhenning3d @SpaceX Tiles will be on hot side of flaps too. A very tough problem is sealing the moving flap to body joint without melting or shredding the seal.”

“@RGVaerialphotos @SpaceX I’m proud to say that that nose is pointier than it needs to be haha”

“@johnkrausphotos @SuperclusterHQ @SpaceX 👍”

“@johnkrausphotos @Patreon @SuperclusterHQ @SpaceX Maybe this should be the flag of Mars”
