@TJ_Cooney Wow, 2011 seems like eons ago! With fairing recovery, Falcon is ~80% reusable, but reflight takes several days & requires boats. Starship will be fully reusable with booster reflight possible every few hours & ship reflight every 8 hours. No boats needed.

Great work by SpaceX Dragon team & Airborne! To be clear, we’ve only done 1 multi-parachute test of Mk3 design, so 9 more left to reach 10 successful tests in a row.

Anyone who’s interested in working on cutting edge manufacturing — designing & building the machine that makes the machine — please consider working at Tesla or SpaceX. We’re gonna take this to a whole new level!

Hardest, most painful thing I’ve ever been through, including getting Falcon to orbit.

@HarryStoltz1 @neiltyson @Space_Station Big challenge for Starship refueling on the moon is finding sources of carbon. Probably some pretty big deposits in craters from meteorites. Same goes for hydrogen & oxygen, also in (shadowed) craters.

@Erdayastronaut Depends on total system efficiency & how long the propellant plant can run to refill Starship, so 1 to 10MW as a rough guess

@SciGuySpace We had to reallocate some resources to speed this up & received great support from Airborne, our parachute supplier. I was at their Irvine factory with the SpaceX team on Sat and Sun. We’re focusing on the advanced Mk3 chute, which provides highest safety factor for astronauts.

@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.

@flcnhvy @Erdayastronaut @Cor_SPACE No, we’ve been focusing on production (now on SN12). Only need 250 bar or even a bit less for Starship/Super Heavy. Anything above 250 is nice to have & we’ll get around to it, but not needed for flight.

@The_ShadowZone @DJSnM For sure more than one pass coming back to Earth. To Mars could maybe work single pass, but two passes probably wise.

@DJSnM Exactly. For reusable heatshield, minimize peak heating. For ablative/expendable, minimize total heat. Therefore reusable like Starship wants lift during high Mach reentry for lower peak, but higher total heat.

@Teslarati Great work by SpaceX parachute engineering! The Crew Dragon parachutes are way more difficult than they may seem. The Apollo program found them to be so hard that it became a notable morale problem!

@Teslarati The hex tiles are actually mechanically attached, which is important to allow for very high temp on back side of tile that would destroy any adhesive. Marshmellow-looking thing is a rope seal.

@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 @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.
