“@Some1gee @Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy It’s a factor. Main reason is that FFSC is the ultimate architecture for converting propellant into rocket velocity.”

“@SpaceXFan97 @Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy Same as last time, although we made a design improvement that could yield about 7 bar more”

“@urnamma After Starship returns from orbit”

“@Perky3327 @Erdayastronaut Mars belongs to the Martians”

“Accelerating Starship development to build the Martian Technocracy”

“@Cmdr_Hadfield @SpaceX @OurWorldInData Exactly. And many areas of countries showing good Internet actually have poor or no access, so those are important to address too.”

“@marshgre @Model3Owners One of my favorite original Roadster colors!”

“@flcnhvy @bluestonenew @DigitalTrends @SpaceX Might get pushed to next month. Starhopper flight first. Waiting on engine repair.”

“@bluestonenew @DigitalTrends @SpaceX 10 years ago, SpaceX server room was named Skynet as a joke. Fate 🖤 irony.”

“@JohnnaCrider1 @NASA @SpaceX @NASA_Technology @reddit Thanks 😀”

“Falcon Rising https://t.co/XnXlTL8lhI”

“@Erdayastronaut @SpaceX Fun!”

“Upcoming Falcon Heavy 🚀 & 🛰 details”

“@Timcast Working on Starship”

“@AnthonyFinno @RobertOHaver @Tesla Tesla is affecting powerful vested interests. Big auto & oil companies aren’t known for their gentle behavior. SpaceX is battling US military prime contractors & space programs of national govts. No walk in the park there.”

“@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.”

“@PPathole @Erdayastronaut @rmarcilhoo @kimitalvitie @SpaceXNow @ChrisG_NSF @NASASpaceflight Add 2 to 4 more Raptors for Starship point to point on Earth. You can go surprisingly far, even with low lift/drag. This was an unexpected result.”

“@kimitalvitie @Erdayastronaut @SpaceXNow @ChrisG_NSF @NASASpaceflight Wings/flaps & leg design changing again (sigh). Doesn’t affect schedule much though.”

“@kimitalvitie @Erdayastronaut @SpaceXNow @ChrisG_NSF @NASASpaceflight Not bad”

“@Erdayastronaut @rmarcilhoo @kimitalvitie @SpaceXNow @ChrisG_NSF @NASASpaceflight Exactly. We’re on the wrong planet for SSTO. No problem on Mars or any of the moons.”

“@SPEXcast @WentaiW @1DarknessSoul5 @SpaceX Good idea”

“@WentaiW @1DarknessSoul5 @SpaceX True. I’m a gamer & my boys are too. Starlink is designed to be great even for competitive twitch reflex games.”

“@fcain @varunversion1 @Erdayastronaut @SpaceX Would love to do exactly that”

“@Cosmic_Penguin Agreed, sent a note to Starlink team last week specifically regarding albedo reduction. We’ll get a better sense of value of this when satellites have raised orbits & arrays are tracking to sun.”

“@fcain @varunversion1 @Erdayastronaut @SpaceX Exactly, potentially helping billions of economically disadvantaged people is the greater good. That said, we’ll make sure Starlink has no material effect on discoveries in astronomy. We care a great deal about science.”

“@John_Gardi @13ericralph31 @varunversion1 @Erdayastronaut @SpaceX Rotate on one axis. Magnetic torque rods for desaturation of momentum wheels.”

“@GoForStaging @13ericralph31 @varunversion1 @Erdayastronaut @SpaceX Yes, already planned. We avoid use of certain lower Ku frequencies specifically for radio astronomy.”

“@1DarknessSoul5 @SpaceX Aiming for sub 20ms latency initially, sub 10ms over time, with much greater consistency than terrestrial links, as only ever a few hops to major data centers”

“@13ericralph31 @varunversion1 @Erdayastronaut @SpaceX If we need to tweak sat orientation to minimize solar reflection during critical astronomical experiments, that’s easily done. Most orbital objects are close to Earth btw, as shown by this NASA density map. https://t.co/83MwIZAEP6 https://t.co/NllMXregRg https://en.m.wikipedia.org/wiki/Space_debris”

“@varunversion1 @Erdayastronaut @SpaceX There are already 4900 satellites in orbit, which people notice ~0% of the time. Starlink won’t be seen by anyone unless looking very carefully & will have ~0% impact on advancements in astronomy. We need to move telelscopes to orbit anyway. Atmospheric attenuation is terrible. https://t.co/OuWYfNmw0D”

“@Erdayastronaut @SpaceX No, Raptor uses a large number of coaxial swirl injectors, which (we believe) achieves highest theoretical mixing/combustion efficiency.”

“@Erdayastronaut @SpaceX Super proud of SpaceX propulsion/test/materials team! One of hardest technology problems. New high temp superalloy & internal foundry needed to make it work. Foundry iteration interval is ~3 weeks from design to flight part vs ~36 weeks typical for aerospace.”

“@SPEXcast @Erdayastronaut @SpaceX Propellant stays same, but almost everything else improves. Fundamental goal is minimize cost per ton to surface of Mars.”

“@Erdayastronaut @SpaceX Great video. Couple notes: Raptor designed for subcooled CH4/O2, so propellant density & thrust increase up to ~8%, as needed for mission. 380 Isp & up to 50% thrust/weight improvement over time. Merlin thrust/weight doubled from V1, but Raptor is closer to optimum.”

“@John_Gardi @Marco_Langbroek @SpaceX Yes”

“@MarcusHouseGame @SpaceX 👍”

“@SpaceX Krypton thrusters operative, satellites initiating orbit raise every 90 mins”

“@SpaceXFan97 @kateconger So far, so good”

“@SpaceX Fairing halves recovered https://t.co/F82LE8JlLJ”

“@SpaceX Krypton ion thrusters activate in about 3 hours to raise orbit”

“@SpaceX All 60 Starlink satellites online, solar array deployment coming up soon”

“@Erdayastronaut @SpaceX @KerbalSpaceP Thanks! Yeah, that’s pretty close.”

“@nichegamer @flcnhvy @Erik2be @Teslarati Tower with Knight is across road from SpaceX, looking at rocket”

“@EcoHeliGuy @Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX Yes, will be used for rear cargo storage. Also helps manage center of mass for heavy payloads when forward cargo is full.”

“@Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX Outer engines are attached to the edge of the airframe to give the center engines room to move”

“@Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX ~2.8m”

“@alijamalashraf @Erdayastronaut @MichaelGalanin @SpaceX Turbines on hot side (outer fan-looking things in this depiction), but this is just to illustrate the type of engine. Our turbopumps are vertical, have 3 fan-looking things on pump side & complex cross-flow. Liquid oxygen turbopump is integrated with main combustion chamber.”

“@Erdayastronaut @Malcolmmarsman @flcnhvy @marstronauts @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX Horizontally”

“@flcnhvy @Malcolmmarsman @marstronauts @Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX First flights would have fewer, so as to risk less loss of hardware. Probably around 20.”

“@Malcolmmarsman @flcnhvy @marstronauts @Erdayastronaut @JaneidyEve @13ericralph31 @SPEXcast @bluemoondance74 @Orion_Sword @Some1gee @SpaceX 3 months”
