“@MarcusHouseGame Rapid & complete rocket reuse, low cost propellant, orbital refilling & propellant production at destination are the four essential elements of making life multiplanetary”

“@Adamklotz_ @SpaceX BN1 is a manufacturing pathfinder, so will be scrapped. We learned a lot, but have already changed design to BN2. Goal is to get BN2 with engines on orbital pad before end of April. It might even be orbit-capable if we are lucky.”

“@SawyerMerritt Cybertrucks get preferential parking, as they look much more futuristic than normal cars and are poetically aligned with the stainless steel of Starship”

“@breezefps Starlink inter-satellite laser links should be operational by end of year. This will dramatically reduce global latency. Light travels ~40% faster in vacuum/air than in fiber optic cables & satellite path length is shorter (cables follow coastlines).”

“@PPathole @Teslarati @13ericralph31 If we are able to make life self-sustaining on Mars, we will have passed one of the greatest filters. That then sets us up to become interstellar. Earth is ~4.5B years old, but life is still not multiplanetary and it is extremely uncertain how much time is left to become so.”

“@WholeMarsBlog @FutureJurvetson @Tesla @karpathy Bot is not directly on the path of accelerating a sustainable energy future, but it aspirationally improves the probability that the future is good”

“@PPathole @arstechnica @SciGuySpace If 2021 manifest is met, SpaceX will do ~75% of total Earth payload to orbit with Falcon. A single Starship is designed to do in a day what all rockets on Earth currently do in a year. Even so, ~1000 Starships will take ~20 years to build a self-sustaining city on Mars.”

“@S3XYstarship @PPathole @Gfilche @MadeInTheUSANJ Yeah, although I hesitate to admit that, because there are a lot of people that foam at the mouth if you even mention his name!”

“@JasonDanheiser @WholeMarsBlog @28delayslater Self-driving cars & useful humanoid robots require a sophisticated understanding of reality. I am increasingly convinced that they are on the path to solving AGI. Should AGI be solved? I don’t know, but humanity is moving rapidly in this direction whether I like it or not.”

“@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.”

“@Erdayastronaut @TJ_Cooney @lrocket @SpaceX @FelixSchlang @MarcusHouseGame He became a big fan of methane, but was not pushing it initially. That came from me reading about Soviet methane engine tests that got over 380 Isp. At that Isp, a subcooled methane stage gets slightly better delta-V than a hydrogen stage.”

“@MarcusHouseGame @bcart03 @nextspaceflight @NASASpaceflight Starship legs are one of the hardest problems. Externally mounted legs require shielding, which adds mass. Wider stance adds mass. Shock absorbers add mass. That said, we need better legs.”

“RT @Starlink: Devastating to hear of the earthquake’s toll on Thailand and Myanmar. The SpaceX team is prepared to provide Starlink kits to…”

“@28delayslater @PPathole @SpaceX It’s basically the plot of Fallout: New Vegas”

“@PPathole @jack Still early stages on that. Getting Starship reliably to orbit, then achieving full & immediate reusability of both stages is by far top priority.”

“@PPathole @johnkrausphotos @SpaceX Two of the engines need slight repairs, so will be switched out”

“@SciGuySpace I think we can do it. Progress is accelerating. Starship offers a path to far greater payload to the Moon than is currently anticipated in the Artemis program. A permanently crewed Moon base is possible.”

“@PPathole That’s when all life on Earth will be boiled off. What matters is how long civilization is capable of making the jump to Mars. This could be a very short period of time measured in decades. It took 4.5 billion years to get to this point & civilization isn’t looking super stable.”

“@TeslaGong @PPathole @SpaceX There is a profound difference between single-planet & multiplanet species. If we are able to visit other stars one day, we may discover many long-dead single-planet civilizations.”

“@AstroJordy @PPathole @SpaceX @Tesla That version of Falcon 1 never flew, so must be ~2004. The CAD looks so simple! I think we were still using SolidWorks back then.”

“@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.”

“@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.”

“@TJ_Cooney @lrocket @SpaceX @FelixSchlang @MarcusHouseGame Tom is great & was instrumental in developing early versions of Merlin & Kestrel, but not later versions of Merlin or Starship/Raptor”

“@ace_constantine @NASAEarthMars I love the inverse poetry of making metaphors literal”

“@PeterDiamandis With the advent of Starship, there is finally a path to solar-powered AI satellites at massive scale. It is the only path I can see that would allow for deployment of 1TW/year of AI.”

“@stevenmarkryan @WholeMarsBlog Heard Diablo IV might be good. Remake of System Shock out soon.”

“@teslaownersSV @PPathole @SpaceX Will take of it”

“@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.”

“@agoyal00 @WholeMarsBlog @PPathole @Gfilche @MadeInTheUSANJ Yes. It’s safe to say that Mackenzie [ahem] Scott is not exactly a big fan of her ex-husband. Unfortunately, a lot of others are getting caught in the crossfire.”

“@PPathole @Adamklotz_ @AaronS5_ @crheller @SpaceX Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber”

“@PPathole @breezefps Best outcome would be to route packets from Starlink user terminal to ground station on roof of server center. Then it doesn’t even touch the regular Internet.”

“@PPathole @thesheetztweetz @waEMD @SpaceX @SpaceXStarlink @WANationalGuard Average latency will improve as more satellites launch (directly above you more frequently) & more ground stations are deployed. As we’re able to put more ground stations on roofs of server centers, legacy Internet latency will be zero.”

“@TJ_Cooney @lrocket @SpaceX @FelixSchlang @MarcusHouseGame That sounds correct. Tom certainly deserves a lot of credit for his excellent work on those engines! Dean Ono too for Kestrel & Draco.”

“@PPathole @_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX That’s the number that really matters”

“@PPathole @_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX Cumulative mass to orbit per year (corrected for GTO & other high energy orbits) is the best comparative metric imo”

“RT @MarioNawfal: 🚨T-MOBILE AND STARLINK STEAL SUPER BOWL SPOTLIGHT T-Mobile's big game ad reveals public rollout of Starlink satellite tex…”

“@PPathole @Erdayastronaut @farrier_nyker @GeetPurohit3 @YoavOffek Looks about right. Ice mining/refining on Mars & maximizing total system efficiency will be hard. CO2 is easy, as Mars atmosphere is mostly that. Also has good amount of N2, which is important for life.”

“@13ericralph31 @PPathole @Erdayastronaut @rmarcilhoo @kimitalvitie @SpaceXNow @ChrisG_NSF @NASASpaceflight Yeah, *way* better. Dramatically improves cost, complexity & ease of operations. Distances of ~10,000 km with decent payload seem achievable at roughly Mach 20.”

“@MarcusHouseGame @Neopork85 @SpaceX @Erdayastronaut @SpaceToday1 @ElonsWorld @FelixSchlang @ChrisG_NSF @DJSnM Yes. This is the hardest part of the booster design.”

“@C3LT_Games The Cape is one of the two Starship build sites. More on this later.”

“@Robotbeat Humanity was on a path of increasing launch cost and diminishing capability, so it might never have happened. SpaceX is an attempt to change that, but we still have a very long way to go to make life multiplanetary.”

“RT @MarioNawfal: STARLINK’S MOST SAVAGE TEST YET: DIABLO HARDCORE Elon just played Diablo Hardcore to test Starlink. One blink of lag = i…”

“Great video of Starship Super Heavy Booster landing as seen from Mexico! 🇲🇽 https://t.co/R695MUaicc”

“Even rockets need hugs 🥰 https://t.co/oF36F0AvBf”

“This is the final straw. Because of this law and the many others that preceded it, attacking both families and companies, SpaceX will now move its HQ from Hawthorne, California, to Starbase, Texas.”

“Given the terrible flooding in Rio Grande do Sul, @Starlink will donate 1000 terminals to emergency responders and make usage for all terminals in the region free until the region has recovered. I hope the best for the people of Brazil. https://t.co/NK6kjz7Iag”

“In support of the people of Venezuela 🇻🇪 [@Starlink] Starlink is providing free broadband service to the people of Venezuela through February 3, ensuring continued connectivity.”

“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”

“We have accelerated the rollout of Starlink direct to cell phone connectivity for areas affected by the hurricanes. This is being provided free of charge by SpaceX and TMobile to help those in need.”

“Apologies to those expecting Cybertruck deliveries in California over the next few days. We need to use those trucks as mobile base stations to provide power to Starlink Internet terminals in areas of LA without connectivity. A new truck will be delivered end of week.”
