@realRickyReeves @Erdayastronaut @NASA Crew Dragon is capable of propulsive landing, but would require extensive testing to prove safety. Better to focus on Starship.

@JaneidyEve We’re now building flight design of Starship SN1, but each SN will have at least minor improvements, at least through SN20 or so of Starship V1.0.

@flcnhvy Starship steel decision came first. We were going to use titanium skins for Cybertruck, but cold-rolled 30X stainless is much stronger.

@Malcolmmarsman @flcnhvy No problem. We could program Starship to perform Swan Lake in the sky. Minimizing landing burn propellant mass is what’s hard.

@flcnhvy If we build as many Starships as Falcons, so ~100 vehicles & each does 100 tons to orbit, that’s a capacity of 10 million tons of payload to orbit per year

@flcnhvy Payload to orbit per year of Starship fleet is most mind-blowing metric, as it’s designed to fly 3X per day, which is ~1000X per year

@TJ_Cooney That said, most Starship spaceports will probably need to be ~20 miles / 30km offshore for acceptable noise levels, especially for frequent daily flights, as would occur for point to point flights on Earth

@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.

@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

@annerajb @Jennerator211 @Erdayastronaut With rare exceptions, composites would make Starship heavier. They don’t stand up well to high temperatures, but steel does great.

@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.

@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 @SpaceX Thanks. Starship, which aspires to be fully & immediately reusable in super heavy class, is a truly 🥜🚀. Even though I’m immersed in Starship/Raptor design & build 7 days/week, it still doesn’t feel real.

@Teslarati Wouldn’t read too much into this. Likely to be fewer F9/FH flights, but possibly an order of magnitude more than these numbers in Starship flights.

@Erdayastronaut @goathobbit Testing a possible Starship windward side ceramic tile. Maximizing emissivity is best for conductive/particle heating. Nice thing about steel is that tiles can be very thin, unlike carbon fiber or aluminum airframe.
