@justpaulinelol @KeithMansfield @Erdayastronaut If 20km works, then orbit

@KeithMansfield @Erdayastronaut Great summary of the key points!

@OranMaliphant @Erdayastronaut @AngelNDevil2 @MarkChica @FutureJurvetson @bluemoondance74 @SpaceX That’s about right, except no sensors. Tile itself is the sensor as it will partially ablate where too hot & have to be replaced.

@AngelNDevil2 @MarkChica @FutureJurvetson @bluemoondance74 @SpaceX It’s all the “secondary” structure that concerns me, not engines & primary airframe

@AngelNDevil2 @MarkChica @FutureJurvetson @bluemoondance74 @SpaceX Raptor cost is tracking to well under $1M for V1.0. Goal is <$250k for V2.0 is a 250 ton thrust-optimized engine, ie <$1000/ton

@JohnnaCrider1 @RationalEtienne @LaurenRow5 @RenataKonkoly @Kristennetten @EvaFoxU @MemesOfMars @PositivePyrami1 Stop sending me this 💩 🤣🤣

@RationalEtienne @LaurenRow5 @EvaFoxU @Kristennetten @SteveHamel16 @TheElonMasked @MemesOfMars @MichellBasler @mayemusk @kimbal Agreed & such a heartwarming photo ♥️

@Kristennetten @SS4Adrian I have that exact thought every time I get the flu

@SS4Adrian Clearly a sign of the apocalypse!

@engineers_feed Lot of ways to melt & join steel. Mostly just needs to be welded consistently & with precise parts.

@engineers_feed Thankfully not. FSW is very difficult to get right & not needed with steel.

Production version will be a lot more polished than this prototype, but still fun to see

@ColinPearceUK Bigger flaps/fins at rear also moves center of pressure back

@TrevorMahlmann Haha yes

@HarryStoltz1 In solving for a good Mars climate, we will learn a great deal about how to do so on Earth. It is the inverse problem.

Inside Starship cargo bay. Header tanks mounted in tip of nosecone to offset engine weight at rear. https://t.co/EJSwqMCooA

@EvaFoxU @DisruptResearch @Tesla @karpathy Cool video!
