“Government absolutely needs to be re-engineered. It is a wasteful mess that is bankrupting America and spending the hard-earned money of taxpayers in foolish ways.”

“@spacesudoer Shana is awesome. Many years ago, I asked her to lead the early VTOL development of Falcon (aka Grasshopper) and she did great work. Now, Shana is a senior member of the Starship engineering team.”

“@nickfloats Raptor 3 will aim for 300 tons of thrust at liftoff, so 10,000 tons of combined thrust for 33 engines”

“Just inspected the Starship booster, which the arms have now placed back in its launch mount. Looks great! A few outer engine nozzles are warped from heating & some other minor issues, but these are easily addressed. Starship is designed to achieve reflight of its rocket… https://t.co/oWZoOOfHmk”

“@MarcusHouse Some of the outer engine nozzles are a little warped from high heating & strong aero forces. Easily fixable.”

“SpaceX engineers are trying to deliver Starlink terminals & supplies to devastated areas in North Carolina right now and @FEMA is both failing to help AND won’t let others help. This is unconscionable!! They just took this video a few hours ago, where you can see the level of… https://t.co/abpOsfNenF”

“@ajtourville @fema @SpaceX This is from a highly trusted, highly competent SpaceX engineer”

“Just received this note from a SpaceX engineer helping on the ground in North Carolina. @FEMA is not merely failing to adequately help people in trouble, but is actively blocking citizens who try to help! “Hey Elon, update here on site of Asheville, NC. We have powered up two…”

“@PlanetOfMemes If someone is a great nurse, doctor, engineer, carpenter, plumber, electrician, teacher, scientist, etc, they should be welcomed!”

“@engineers_feed That’s deep 😂 Most people don’t understand that the reason tall buildings don’t fall down is because of structural engineering, not architecture”

“@ajtourville @xai @Tesla Haven’t read the article, but the above is not accurate. Tesla has learned a lot from discussions with engineers at xAI that have helped accelerate achieving unsupervised FSD, but there is no need to license anything from xAI. The xAI models are gigantic, containing, in…”

“@RenataKonkoly @lrocket Yeah, game-changer! We do still use COPVs for a few things on Starship, like nitrogen purge and engine spin start.”

“@cb_doge Merlin seems like such a simple engine these days, but it sure is a solid workhorse!”

“@EPavlic @breckyunits @bchesky Just leaving Tesla engineering offices in Palo Alto. Mostly good, some bad. The future is going to be wild. There will be so many robots …”

“@Lukeleisher Tom is awesome. Taught me an immense amount about liquid rocket engines. And he’s just a great guy.”

“@engineers_feed The Romans won their wars through engineering”

“@SpaceX Important to note that the induced mass (mass required by a given engine design that is not the engine itself) of Raptor 3, while far better than Raptor 2, still has a lot of room for improvement. Thrust will exceed 300 tons with Raptor 3.x (thrust/mass>200), enabling 10,000…”

“The amount of work required to simplify the Raptor engine, internalize secondary flow paths and add regenerative cooling for exposed components was staggering. As a result Raptor 3 doesn’t require any heat shield, eliminating heat shield mass & complexity, as well as the fire…”

“@engineers_feed So long as no one *actually* tries to open the door / assassinate, it will seem like Fort Knox”

“Both @Tesla and @xAI are looking to hire networking engineers & technicians”

“@SERobinsonJr Upper stage restart to raise perigee resulted in an engine RUD for reasons currently unknown. Team is reviewing data tonight to understand root cause. Starlink satellites were deployed, but the perigee may be too low for them to raise orbit. Will know more in a few hours.”

“@BasedBeffJezos Waterloo is a great engineering school. Almost went there instead of Queens, but (at least back then) the campus was almost entirely dudes. Very limited dating pool.”

“@engineers_feed Jason.json”

“Over 5 million pounds of thrust from 27 engines”

“@Erdayastronaut @Teslaconomics @SpaceX We could build a lot more, but the next version of Raptor is really the one to scale up production. We begin testing it in McGregor within a week or so. Regenerative cooling and secondary flow paths have been made integral to the whole engine, thus no heat shield is required.…”

“@___frye Engineering is fun for me, whereas politics and posting on controversial issues feels like putting my hand on a hot stove – mega pain. The reason I do the latter, admittedly ineptly at times, is because I think it is necessary to counteract corrosion of civilization.”

“Starlink just achieved a new internal median latency record of 28ms yesterday! Great work by the engineering and operations teams.”

“@Supreme_Owl_FTW @paulg @jonatanpallesen True in many ways. Besides being a stimulant, percolation of coffee led to some of the ideas behind the steam engine.”

“@paulg @jonatanpallesen The critical factor was the commercial steam engine, as usable energy per human was no longer limited by what people and animals could eat. The ability to reliably burn coal at scale to move things was an Earth-shattering breakthrough. https://t.co/cNaut6NZ03 https://en.m.wikipedia.org/wiki/History_of_the_steam_engine”

“@tsarnick Not far wrong for engineering orgs”

“@engineers_feed SpaceX has the most efficient argon ion thruster ever made at 69%. No kidding. Not 68, not 70, actually 69 😂.”

“@engineers_feed There are actually a lot of ways to interpret the word “cathode”, but, for those who make batteries/cells, it is the side with metal and the anode is the side with carbon and/or silicon”

“@esherifftv @lrocket As it turns out, future versions of Raptor will ultimately exceed 700k lb-F! Honing T/W, Isp and reliability are much harder than thrust though. Rocket engines desperately want to explode.”

“Whoa, I just realized that raising a kid is basically 18 years of prompt engineering 🤯”

“@engineers_feed We are a mobile cell colony of 30 to 40 trillion cells”

“@SawyerMerritt Tesla is increasing comp (contingent on progress milestones) of our AI engineering team”

“@SawyerMerritt Ethan is very talented, but “vision chief” would be overstating things. There are over 200 excellent engineers in the Tesla AI/Autonomy team. Tesla’s pace of progress with autonomy is accelerating. The talent war for AI is the craziest talent war I’ve ever seen!”

“@SawyerMerritt Ethan was going to join OpenAI, so it was either xAI or them. They have been aggressively recruiting Tesla engineers with massive compensation offers and have unfortunately been successful in a few cases.”

“@RichardDawkins That is not my experience. I also think the distinction between science and engineering is a foolish one, aimed primarily at puffing up the self-importance of those who call themselves the former. What actually matters is working on the limiting factor. Sometimes, that is…”

“@MarioNawfal There may be some former SpaceX engineers working there, but SpaceX is not backing this company”

“@ScottPolhamus @Teslaconomics Did they? I have a lot of respect for Porsche engineering, although they have some ways to go with electric to match their combustion skills. When they take it apart, they will discover a lot of new technology.”

“@leahnoelnielsen @SawyerMerritt @LucidMotors 1. He was never chief engineer, I was 2. He arrived after Model S prototype 3. He left before production started”

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

“@engineers_feed g String Theory”

“@engineers_feed 😂”

“@heydave7 So much engineering has gone into the hands. In a year, it will be able to thread a needle.”

“@engineers_feed From the standpoint of when physics predicts an “end” to the universe, being 13.8 billion years is still extremely young https://t.co/mlVaKPONt9. https://en.m.wikipedia.org/wiki/Future_of_an_expanding_universe#:~:text=22%20billion%20years%20in%20the,the%20Higgs%20field%20is%20metastable”

“@EvaFoxU The premature death of a rocket engineering genius was a great blow”

“@GailAlfarATX Starship has 33 engines! If an engine failure is isolated, then many engines greatly increases reliability (Starship only loses <3% of thrust). If not, then reliability is terrible. The difference is at least 2 orders of magnitude.”

“@engineers_feed @Tesla * some assembly required”
