@Erdayastronaut @JHC2718 @MagnussonMani @vicvic21266 @flcnhvy @DJSnM @KevinKling12 @spaceXcentric Failure rate is actually both higher & lower than that, as the Falcon 9 design has changed almost completely several times. Currently flying version has no failures (may fate continue to be merciful), but older versions therefore have a higher failure rate.

@Erdayastronaut @IvanEscobosa @DJSnM @KevinKling12 @spaceXcentric Precisely

@Erdayastronaut @DJSnM @KevinKling12 @spaceXcentric Distance from fireball is 0.5*a*t^2, so if t is small, you haven’t moved far even if a is high. At ~6g thrust, you’ll only travel ~0.03m in 100 ms. Pressure wave (aka explosion) with liquid rockets is low, as ox & fuel are poorly mixed. If you can fly out of it, you’re prob ok.

@Erdayastronaut @vicvic21266 @flcnhvy @DJSnM @KevinKling12 @spaceXcentric 🤣🤣

@flcnhvy @DJSnM @Erdayastronaut @KevinKling12 @spaceXcentric You know destination weather before departure & there’s no weather in space

@flcnhvy @DJSnM @Erdayastronaut @KevinKling12 @spaceXcentric Everything happens so fast. It’s such a different paradigm that applying aircraft concepts to rockets is almost like applying shipping concepts to aircraft. Travels 10,000 km in 30 mins.

@DJSnM @Erdayastronaut @KevinKling12 @spaceXcentric Not currently planning for pad abort with early Starships, but maybe we should. Vac engines would be dual bell & fixed (no gimbal), which means we can stabilize nozzle against hull.

@Erdayastronaut @DJSnM @KevinKling12 @spaceXcentric Raptor turbines can spin up extremely fast. We take it easy on the test stand, but that’s not indicative of capability.

@Erdayastronaut @KevinKling12 @DJSnM @spaceXcentric Over time, 355 & 385 are possible, but very difficult

@SpaceXFan97 @Erdayastronaut @KevinKling12 @DJSnM @spaceXcentric Most likely

@EvaFoxU @justpaulinelol @flcnhvy @tarimnazmi Photoshop is amazing

@Erdayastronaut @KevinKling12 @DJSnM @spaceXcentric Sea level Raptor’s vacuum Isp is ~350 sec, but ~380 sec with larger vacuum-optimized nozzle

@Erdayastronaut @flcnhvy @tarimnazmi For sure

@justpaulinelol Actually true

@dStanca Hoping to open in Romania soon!

@tarimnazmi Definitely

Probability that we’re in base Polytopia is highly unlikely - KWM

@MikeHudema @GretaThunberg Wow cool

Why aren’t more people talking about this!? https://t.co/iUFIBcDQrp
