“RT @ApoStructura: Starship vs A380 & 737-8 When stacked with the Super Heavy booster Starship is taller than an A380 and a Max-8 on top of…”

“@WholeMarsBlog What has become absolutely clear is that the plethora of self-driving corner cases can only be solved with real-world optical intelligence. This is how humans designed the road system to work. Once you have that in silicon form, everything else is just icing on the cake.”

“@SciGuySpace It’s a step in the right direction, but they should really aim for full reusability by 2026. Larger rocket would also make sense for literal economies of scale. Goal should be to minimize cost per useful ton to orbit or it will at best serve a niche market.”

“@teslaownersSV Later this year, if fate smiles upon SpaceX, the ship will be caught by the tower, just like the booster”

“RT @spacesudoer: Starship fully stacked for Flight 9. Launch NET May 27. https://t.co/GdM6aljIRU”

“@SpaceX And other places”

“@PPathole @SpaceX @Tesla That was my night job. Day job was working on ruthenium-tantalum ultracapacitors at Pinnacle Research.”

“@shortword @M3Marcel @WholeMarsBlog Current efficiency is 1.7kWh/mile, but there is a clear path to 1.6, possibly 1.5”

“@torybruno Your company said the exact opposite in 2014 when it got a sole-source, uncompeted $11B DoD launch contract. https://t.co/Abd5sWhZDt In any event, expendable rockets are as relevant to the future as expendable aircraft. Rapidly reusable rockets are all that matter. https://www.cbsnews.com/network/news/space/home/spacenews/files/042914_ula_blockbuy.html”

“@WholeMarsBlog Beta V8.3 has literally ~1000 improvements. Will take time to QA internally before release probably in two or three weeks.”

“@GailAlfarATX @SawyerMerritt Wow, working on this problem has soaked up a lot of my time & brain cycles over the past ~7 years! This and Starship engines are currently the two hardest problems.”

“@Andercot But the good news is that SpaceX will put big telescopes in space and giant ones on the Moon”

“@DimaZeniuk @Starlink @SpaceX @SpaceXStarlink Temporary experiment to test price elasticity of demand”

“@Erdayastronaut @thesheetztweetz @BryceSpaceTech @SpaceX @Arianespace @ArianeGroup @roscosmos @northropgrumman @ulalaunch @torybruno @isro @RocketLab True”

“RT @SpaceX: Views of SpaceX's two Florida launch pads from space”

“@_rykllan @FelixSchlang @spaceXcentric @MarcusHouseGame @SpaceX Anyone tracking tonnage to orbit per year for all launch vehicles?”

“@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.”

“@SPEXcast @TrungTPhan Starship will be crushingly cost-effective for Earth orbit or moon missions as soon as it’s operational & rapid reuse is happening. Mars is a lot harder, because Earth & Mars only align every 26 months, so ship reuse is limited to ~dozen times over 25 to 30 year life of ship.”

“@WholeMarsBlog 😂”

“RT @SoveyX: SpaceX now has over 10,000 Starlink satellites in orbit, which is honestly an absurd engineering achievement. And no, they are…”

“@rustyrockets What are you talking about? Nothing has changed.”

“Conducted hold-down firing of returned Falcon rocket. Data looks good overall, but engine 9 showed thrust fluctuations.”

“@TimFernholz Efficiently reusable rockets are all that matter for making life multiplanetary & “space power”. Because their rockets are not reusable, it will become obvious over time that ULA is a complete waste of taxpayer money.”

“@marshallk @Esqueer_ Absolutely”

“@AngelNDevil2 @torybruno What is not well understood is that ULA *still* has a monopoly carve-out for US government launches for which SpaceX is not allowed to compete, costing the taxpayer twice as much per launch than it should. This is obviously not real competition.”

“@WholeMarsBlog Yeah”

“@iamtomnash The Fox anchor is talking utter nonsense. I challenged Putin to a physical fight over Ukraine and SpaceX and provided massive support to Ukraine, as the Ukrainian government has repeatedly acknowledged.”

“@MarsUniversityX Yeah”

“@WholeMarsBlog Normally, competitive pressure would force Apple to lower fees, but Apple & Android have a duopoly on phones. When interface familiarity is taken into account, it’s basically a monopoly. The effective 30% sales tax Apple charges is hidden from users or there would be an outcry.”

“RT @johnkrausphotos: OTD 7 years ago: The debut of Falcon 9 Block 5, which has since become the workhorse launch vehicle of the modern era,…”

“@WholeMarsBlog Team is working on it. This will be a different release number.”

“@longmier Hopefully, only a few more months before there are 300 direct to mobile phone Starlink satellites in operation. That is the number needed to achieve continuous coverage over mid latitudes.”

“@DimaZeniuk Slightly different variants of stainless alloys are used in the rocket and truck, but pretty close overall”

“@WholeMarsBlog Vast majority of people have no idea this works”

“@WholeMarsBlog Also, being ruggedized for relentless salt spray & extreme winds & storms in deep ocean is not easy”

“RT @teslaownersSV: Starship will make us multi planetary https://t.co/lFxQuHLWjV”

“@ajtourville @Erdayastronaut @SpaceX Yes, but engines have a min throttle point where there is flameout risk, so landing on 3 engines means high thrust/weight (further away from hover point), which is also risky”

“@Erdayastronaut @SpaceX Absolutely, but to move to Mk3 design. This had some value as a manufacturing pathfinder, but flight design is quite different.”

“@Kristennetten @StianWalgermo @Tesla @ARKInvest @WholeMarsBlog @alex_avoigt @Teslarati @TeslaPodcast @mortenlund89 I was in the Berlin paint shop talking to the team on my last visit. It’s gonna be great! But bear in mind that it takes about a year for a new factory to reach volume production. Production is super hard work, which is why I have great respect for those who do it.”

“@SawyerMerritt @SpaceX The California Coastal Commission should be dissolved as an organization. An utterly insufferable and misanthropic group of Karens if there ever was one!”

“@rmcentush Starship could deliver 100GW/year to high Earth orbit within 4 to 5 years if we can solve the other parts of the equation. 100TW/year is possible from a lunar base producing solar-powered AI satellites locally and accelerating them to escape velocity with a mass driver.”

“@Erdayastronaut @josh_bickett @ajtourville @SpaceX Intuitively, it would seem so, but turbopump-fed Raptors have much higher thrust & propellant mass fraction than pressure-fed gas thrusters & they’re already there”

“@Teslarati Pretty much, although we also sent some Medtronic units, which are meant for extreme situations. Those require a lot of work to set up & operate. Should be used sparingly. SpaceX is making the valve at the heart of that system.”

“@DrPhiltill @adamholtwrites SpaceX has way more satellites in orbit than the rest of the world combined, so maybe we know a thing or two about the subject 🤣 Starlink V3 will be 20kW and launched at scale around Q4 next year. No problem to scale that to >100kW if the satellite mass is shifted towards solar… https://t.co/6wPLn97Vff https://x.com/i/web/status/1998872465087541752”

“Really tempting to redesign upper stage for return too (Falcon Heavy has enough power), but prob best to stay focused on the Mars rocket”

“@mterrace @Investor421 @WholeMarsBlog @28delayslater Is this real?”

“@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.”

“@flcnhvy @ErcXspace Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount — ready to refly in under an hour”

“@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.”
