@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard It’s embarrassing that Boeing/Lockheed need to use a Russian engine on Atlas, but that engine design is brilliant

@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard You def don’t want electric pumps on a rocket engine! Raptor turbopumps alone need 100,000 horsepower per engine. That’s not a typo.

@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard Yes, full flow, gas-gas, staged combustion. Will take us time to work up to 300 bar. That is a mad level.

@NASASpaceflight @_Synders @John_Gardi @martinengwicht @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes. Radically redesigned Raptor ready to fire next month.

@Erdayastronaut @ludan27 @JeromeJaccard @Robotbeat @alan1bernard Seriously! We are just on the wrong planet for SSTO. Mars, no problem.

@_Synders @John_Gardi @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Starlink V1 on Falcon, V2+ on Starship. Basically, all future products will contain either the word “star” or “link” 😀

@ludan27 @Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Yes, but single stage to orbit with no payload is pointless. Add Super Heavy rocket booster & orbital payload is gigantic. Only need booster on Earth, due to deep gravity well & thick atmosphere. Starship alone on moons & Mars.

@John_Gardi @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Coldformed at cryo

@Malcolmmarsman @TheMuddySchmuck @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard This test hopper is at full body diameter of 9m / 30 ft, just not full height. Super Heavy will be full height & diameter.

@TheMuddySchmuck @martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard We’re building subsections of the Starship Mk I orbital design there

@thescalex @Jonas123denmark @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Exactly

@martinengwicht @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard For sheet/plate, at supplier made to our spec. For cast, in our Hawthorne foundry.

@johnkrausphotos @Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Yes

@Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard I will do a full technical presentation of Starship after the test vehicle we’re building in Texas flies, so hopefully March/April

@Erdayastronaut @NASASpaceflight @JeromeJaccard @Robotbeat @alan1bernard Yup. Actually, the only significant design element in common with early Atlas is stainless steel & we’re using a different alloy mix. I super ♥️ 300 Series Stainless!

@Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard While there are some material similarities, Starship is very different from the Atlas design

@Erdayastronaut @JeromeJaccard @Robotbeat @alan1bernard Stainless steel is correct, but different mixture of alloys & new architecture. Unlike Atlas, Starship is buckling stable on launchpad even when unpressurized.

@wangmeister If Tesla committed delivery & customer made good faith efforts to receive before year end, Tesla will cover the tax credit difference

@alan1bernard Coming soon

@wangmeister It will be tight, but Tesla production should have all mid-range Model 3 orders delivered by year end

@MikeKasprzik @Tesla Try connecting to WiFi

Tesla has released all cars for sale where original customer can’t take delivery before year end, as well as test drive / display cars, which cost less. Reminder to US buyers that $7500 tax credit drops in half in 8 days. Order online at https://t.co/46TXqRrsdr or visit stores.
