@peterrhague It’s designed to make life multiplanetary, otherwise extreme overkill for mere Earth sector activity! Starship fleet mass to orbit per year will be more than 1000 times all current Earth rockets combined, including Falcon. Necessary, for a city on Mars.

@Kristennetten @royalsociety More like he gave it his blessing. It was sort of a groundswell of those who believed in the scientific method in London.

Nullius in Verba @royalsociety

@westcoastbill Indeed

@ReflexFunds @nickidk4 @pcgamer Dojo/Doge

@PPathole @Erdayastronaut @rweb11742 Yeah, looks like marginal cost of launch will be less than $1M for more than 100 tons to orbit, so it’s mostly about fixed costs divided by launches per year

@speculawyer @Erdayastronaut @rweb11742 Exactly

@Erdayastronaut @rweb11742 Merlin is a strong local maximum design, but kerosene is suboptimal fuel, no matter what you do. What matters is cost per ton to Mars. CH4 is the only choice imo. Important: O2/CH4 allows OF ratio of ~3.5 vs ~2.5 for kerosene, so ~78% of propellant is oxygen.

@parstalberg @josh_bickett @ICannot_Enough @Erdayastronaut @rweb11742 Yes, but from a visiting American. Ah, the irony is just too much!!

@josh_bickett @ICannot_Enough @Erdayastronaut @rweb11742 Yeah, PCR Ct was unequivocal at <20. Doesn’t matter what method you use at that low a cycle threshold.

@flcnhvy @LUGG4S1 @pcgamer Maybe making some notable changes. Will wait until figurative & literal dust settles.

@ICannot_Enough @Erdayastronaut @rweb11742 Pretty close. Definitely feel 💯 if I take DayQuil. Frankly, this was one of the mildest cold/flu experiences I’ve ever had.

@LUGG4S1 @pcgamer Avionics cables moving to steel pipe shields & adding water-cooled steel pipes to test pad

@LUGG4S1 @pcgamer About 2 secs after starting engines, martyte covering concrete below shattered, sending blades of hardened rock into engine bay. One rock blade severed avionics cable, causing bad shutdown of Raptor.

@Erdayastronaut @rweb11742 The most amazing thing about rocket engines is that they *sometimes* don’t blow up! The amount of power going through them boggles the mind.

@pcgamer We should just count the atoms at this point

@DJSnM @Erdayastronaut @CharlesNOtrumps @rweb11742 Absolutely. Production/testing of rocket engines is over 90% of the problem. This is true in general. For cars, production is over 99% of the problem. That 1% inspiration is very important, but it’s less than 1% of the pain.

@Erdayastronaut @CharlesNOtrumps @rweb11742 Our first Merlin engine design was really bad tbh. Nothing worked well & some parts didn’t work at all. 18 years later & thousands of upgrades make it a great GG cycle engine.

@billhuang688 @JohnnaCrider1 @timmerenginerd @jack Maybe *I* just love irony haha

@GreenIsClutch @JohnnaCrider1 @timmerenginerd @jack They’re on their way! Hopefully, more Teslaquila next month.

@JohnnaCrider1 @timmerenginerd @jack Fate 🖤 Irony

@jack Well said.

@Erdayastronaut @rweb11742 Damn, that’s not easy! I spent quite a bit of time looking at Russian/Ukrainian engines. They’re good.

@PPathole @michaelmina_lab Yes
