15 years of Elon, fully searchable. The production archive uses Supabase as the source of truth, with 94,952 indexed tweets available in development as a full-archive fallback and a curated annotation layer for context, theory, and how major claims aged.
“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas. Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.”
“@TashaARK Additive manufacturing of parts is still far too costly for cars, but can rapidly create tooling to accelerate pace of innovation. It’s already sensible for rocket engine parts. To the best of our knowledge, SpaceX is 2 or 3 years ahead of other companies in use of additive.”
“@torybruno @ChadBowman0 @thesheetztweetz Now, this sort of nonsense happens all the time with government contracts & everyone knows it. However, in this case, it is money diverted from making life multiplanetary, which is the goal of SpaceX, vs the ULA goal of maximizing dividends to Lockheed & Boeing. Not ok.”
“@BryceSpaceTech @SpaceX Still very tiny potatoes compared to what’s needed to make life multiplanetary”
“@WallStreetSilv That was at the SpaceX Texas rocket test site about 4 years ago. We’ve been there since 2002.”
“RT @SpaceX: Booster 18, the first Super Heavy V3, is beginning prelaunch testing. The first operations will test the booster's redesigned p…”
“@Erdayastronaut @TJ_Cooney @lrocket @SpaceX @FelixSchlang @MarcusHouseGame Tom has some great stories about experimenting with premixed O2/CH4 before SpaceX. That is not recommended haha.”
“@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered. Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb. Booster is purging all 33 engine shrouds in flight to prevent this.”
“RT @SpaceX: Falcon 9 completes the first 27th launch and landing of a booster and delivers 27 @Starlink satellites to the constellation fro…”
“@MarcusHouse @LordofEa @kerrikgray @chicago_glenn @Tesla @teslaownersSV @dvorahfr @TonyadeVitti @SpaceX @SirineAti That’s the plan, unless it is damaged in testing. What really matters is that ship & booster production line is spooling up. Also, each new ship & booster has incremental design improvements.”

“@ajtourville @SpaceX The new launch pad is already designed for the 10,000 tons of thrust version, which is almost exactly 3 times more powerful than the Saturn V Moon rocket”
“RT @SpaceX: Falcon 9 lifts off from pad 4E in California ahead of completing the 400th landing of an orbital class rocket and delivering 27…”
“@astro_greek Many funny details on Raptor. The special metal alloy SpaceX created for the rocket nozzles turns green, so we painted Hulk on the first one.”
“RT @SpaceX: Falcon 9 lifts off from pad 4E in California, delivering 27 @Starlink satellites to the constellation. This single booster has…”
“Trying for another rocket landing tmrw. This time on the droneship "Of Course I Still Love You". https://t.co/6LGnzhWLLr https://x.com/spacex/status/614551591601844224”

“@DJSnM @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes.”
“RT @DimaZeniuk: SpaceX launched 138 rockets in 2024, averaging one every 2.6 days https://t.co/z8MzTC6YhQ”

“RT @SpaceX: Falcon 9 landing confirmed, marking the 125th time a first stage booster has landed on the Of Course I Still Love You droneship…”
“@astro_g_dogg Took more work to make F9 booster reuse cost-effective than went into recovering it in the first place. This is an important point. Things finally clicked into place with Block 5. My hat is off to everyone at SpaceX, NASA, Space Force, FAA & suppliers who helped make it happen.”
“@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.”
“RT @SpaceX: Falcon 9 launches 28 @Starlink satellites from Florida and completes the 500th launch and landing of an orbital class booster h…”
“RT @DimaZeniuk: SpaceX lands a Falcon 9 booster for the 400th time https://t.co/QOOyqIW84K”
“@PPathole @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Some small tubes & wiring need to be nested in a bigger tube for thermal protection, kinda like conduit in a house. Engines themselves & booster base are extremely robust. High strength stainless steel is bulletproof to a handgun at ~2.5mm thickness. Booster dome is 4mm.”
“@HSajwanization I hope others succeed too, but at least there is one rocket where success in making life multiplanetary is one of the possible outcomes”
“RT @SpaceX: Side boosters separate from Falcon Heavy https://t.co/iz6g7AONN3”

“@LanceUlanoff Note, gas contained would be ultra high pressure air in a SpaceX rocket COPV bottle. The air exiting the thrusters would immediately be replenished whenever vehicle pack power draw allowed operation of the air pump, which is most of the time.”
“RT @farzyness: Starlink is only possible because of reusable rockets. SpaceX is the only company that does reusable rockets. And they're…”
“RT @teslaownersSV: “My boss Elon Musk founded this company @SpaceX in 2002 with the purpose of building rockets and spaceships to enable pe…”
“@TrungTPhan I came to the (obvious) conclusion that a radical improvement in rocket technology was needed to make life multiplanetary. That required creating a company, as success was not in the set of possible outcomes for the existing rocket companies.”
“@Tenjin37151 @Space_Station @SpaceX @Commercial_Crew @NASA @esa @JAXA_en @astro_kimbrough @Astro_Megan @Thom_astro @Aki_Hoshide As described in The Moon is a Harsh Mistress (great book), a linear accelerator would be great for the moon. Earth’s gravity is too high & atmosphere too dense for accelerators to be a good solution vs reusable boosters imo.”
“RT @xdNiBoR: > Tesla will never succeed > Elon can't start a space company > Neuralink will never work > SpaceX will never reuse a rocket…”
“@Erdayastronaut @SciGuySpace Last launch aborted due to slightly high power. Possibly, but not obviously, related to today. This vehicle has seen a lot of wear, so today isn’t a big surprise. Life leader rockets are used only for internal missions. Won’t risk non-SpaceX satellites.”
“@ashleevance @blueorigin @SpaceX @RocketLab @Firefly_Space @stoke_space Good hope for the future of humanity in space!”
“@FutureJurvetson Boeing and Lockheed moved their rocket production from California to Alabama. SpaceX took over an abandoned aerospace building in LA County and turned it into the highest volume rocket producer in the world. That was because I lived in California.”
“@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.”
“RT @ElonClipsX: Elon Musk: When we started SpaceX, we knew nothing about rockets. “In the beginning, we knew nothing about rockets, and ou…”

“@FutureJurvetson @BryceSpaceTech @SpaceX SpaceX aims to make life multiplanetary, which means that the technology must be orders of magnitude better than companies that just want to put some satellites in orbit”
