“@MarcusHouse A second is a long time to a rocket. Said another way, it was 1000ms or ~50 control cycles away from hitting the tower. Not actually that close.”

“@AngryPackOMeese @dlxinorbit @doug_ellison @dsfpspacefl1ght Maybe that plan works out, but I will seriously eat my hat with a side of mustard if that rocket flies a national security spacecraft before 2023”

“@teslaownersSV We plan to move the display rockets closer to the road”

“Particularly trying to understand the quieter bang sound a few seconds before the fireball goes off. May come from rocket or something else.”

“@RenataKonkoly @Kristennetten @culturaltutor The swoop of the X is meant to represent the rocket’s arc to orbit”

“@PPathole Booster has 2 pins for lifting & catching, although maybe it’s better to modify grid fins to take more load. Something will need to flip out from leeward side of top of ship to do same there. Maybe it’s part of fwd flaps, but prob not. Diff solutions for diff load paths.”

“@farzyness I hope it continues to be routine! You know the revolution in rocket reusability is succeeding when it happens so many times that it no longer makes the news.”

“RT @ElonFactsX: “A lot of people said that rocket reusability was a dumb idea. We've shown that, in fact, it is absolutely the right idea.…”

“@engineers_feed A 10% reduction in g would make orbital rockets so much easier, but a 10% increase would make them almost impossible”

“RT @johnkrausphotos: Closeup of Super Heavy Booster 15’s landing burn during today’s catch and landing https://t.co/vS6jtqYTV4”

“RT @Erdayastronaut: It is still insane they've got the booster to work out so well. 33 engines. That just seems so absurd, yet that's been…”

“RT @cb_doge: “Each Raptor rocket engine produces twice as much thrust as all 4 engines on a 747. There are 33 Raptor engines powering the S…”

“While the rocket does look rather tall & tippy, a stable landing is no problem with proper throttle response https://t.co/B4Y6D4dpsc https://www.youtube.com/watch?v=0UjWqQPWmsY&feature=youtu.be”

“@Erdayastronaut Hot-staging gives the best performance, but needs to be done without blowing up the booster!”

“RT @MarioNawfal: 🚨🇩🇪 AFD SURGES TO 26% IN GERMAN POLLS AS MIGRANT RAPE STATS SPARK OUTRAGE Germany's AfD party just rocketed to 26% in the…”

“We figured out how to design rocket parts just w hand movements through the air (seriously). Now need a high frame rate holograph generator.”

“@AJamesMcCarthy Giant rocket down by the river, next to the highway. Sure sounds implausible!”

“@Erdayastronaut Creating the production system is >1000% harder than building one rocket. This is the truly hard thing.”

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

“@Scobleizer @alirocketeer Cool! Improved video features should land almost every week.”

“Launch in ~1.5 hours if weather clears. Lightning tower struck earlier, but no effect on rocket or satellite http://t.co/AWdx9LsFZt”

“RT @teslaownersSV: “Here's Elon Musk who brought us into the era of electric vehicles, the only person who can shoot off rockets and get th…”

“@SciGuySpace They need to go all-in on reusability or be utterly uncompetitive. Rockets are no different from other transport technologies, just harder to make reusable. No one would buy a single-use airplane, car or even bicycle! You’d need to tow another car just for the return trip 🤣”

“@DrChrisCombs The world doesn’t need another capsule. What matters is fully reusable rockets and spacecraft.”

“Falcon Heavy side boosters can use most of the same airframe as Falcon 9, but center core needs to be buffed up a lot for transfer loads.”

“RT @johnkrausphotos: Starbase is entirely accessible to the public, and the only place in the world you can get this close to a rocket so c…”

“@Erdayastronaut @i_gvf @SciGuySpace Exactly. Chartering a dedicated 747 flight around the world costs less than buying a small, single engine turboprop plane. In the same way, a giant reusable rocket flight is way cheaper than a tiny expendable rocket that can be used only once.”

“Three engine F9R Dev1 vehicle auto-terminated during test flight. No injuries or near injuries. Rockets are tricky …”

“RT @XFreeze: Elon Musk perfectly explains why fully reusable orbital rockets are insanely hard to build Our Earth has quite strong gravity…”

“RT @DimaZeniuk: One year ago today Falcon Heavy boosters made a successful landing https://t.co/MsidCOLP2K”

“@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.”

“@lrocket Congrats!”

“@ArthurMacwaters @MarioNawfal My goal is to fix government IT! This is harder than getting a rocket to orbit. Actually.”

“@ajtourville It is how most of the space industry makes rocket tanks. Works, but is expensive and production is slow.”

“Model S product call at 11 today. Rocket discussion at noon on Monday.”

“@DimaZeniuk The booster flight was a success, the ship flight was 1/4 successful, hence cup being ~5/8 full. New ship forward flaps, higher thrust engines and tile adherence on ascent were tested. Improved heat shield performance was the only major thing that wasn’t tested, along with the…”

“@Teslarati @13ericralph31 Unmodified water tower machines do not work well for orbital rockets, as mass efficiency is critical for the latter, but not the former. Hopper, for example, was made of 12.5mm steel vs 4mm for SN1 orbital design. Optimized skins will be <2mm in places across a 9000mm diameter.”

“@lrocket It is the only way to build a civilization at the Kardashev II scale”

“@MarcusHouse @artzius All Raptors on booster, whether fixed or gimbaling, would be the same. 33*230 gets ~7600 tons of thrust & T/W of ~1.5.”

“Latest rocket test flight: hard lateral deviation, stabilize & hover, rapid descent back to pad http://t.co/Vb7ebiMdNJ http://www.youtube.com/watch?v=2t15vP1PyoA&feature=youtu.be”

“@johnkrausphotos Rockets are hard”

“@Math_files CFD has become super good at predicting reality, except for complex, multi-element combustion in a rocket engine”

“1st firing of Falcon 9-R advanced prototype rocket. Over 1M lbs thrust, enough to lift skyscraper http://t.co/AUCsWTw77E”

“@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.”

“@YounieTyler @astro_g_dogg Booster is more than half cost of mission. Fairing is ~10%.”

“@thejackbeyer @MarcusHouse @artzius Center engines on ship will be same as booster engines. This is basically Raptor 2. Raptor Vacuum would be only variant. Tbd as to whether to commonize R-Vac with Raptor 2 (more thrust), keep same or tighten throat (more Isp). Adding 3 more R-Vac to ship with max Isp maybe …”

“Grasshopper rocket flies up 250m, holds against wind and lands. Vid taken from our hexacopter http://t.co/LXmMCYDD0e http://www.youtube.com/watch?v=NoxiK7K28PU&feature=youtu.be”

“@cb_doge I hope other rocket organizations deliver more mass to orbit, but that doesn’t seem to be happening. We don’t even try to block their progress by filing patents, which almost all technology companies do.”

“@Peter_J_Beck Rapidly reusable rockets will be the only type that matter in the future”

“Mega storm preventing droneship from remaining on station, so rocket will try to land on water. Survival probability <1%.”
