@Erdayastronaut @SpaceX Super proud of SpaceX propulsion/test/materials team! One of hardest technology problems. New high temp superalloy & internal foundry needed to make it work. Foundry iteration interval is ~3 weeks from design to flight part vs ~36 weeks typical for aerospace.

@DJSnM Only a tiny amount. There is enough air to affect the satellites & allow some amount of yaw steering.

@SPEXcast @Erdayastronaut @SpaceX Propellant stays same, but almost everything else improves. Fundamental goal is minimize cost per ton to surface of Mars.

@Erdayastronaut @SpaceX Great video. Couple notes: Raptor designed for subcooled CH4/O2, so propellant density & thrust increase up to ~8%, as needed for mission. 380 Isp & up to 50% thrust/weight improvement over time. Merlin thrust/weight doubled from V1, but Raptor is closer to optimum.

@teslaownersSV @Tesla Whoa cool 😀

@John_Gardi @Marco_Langbroek @SpaceX Yes

Beautiful solar sail

@mcjamez @_jameshatfield_ @danielcincu @Alex_Parker ISS is extremely gigantic & has lights

@danielcincu @Alex_Parker Precisely, sats will be in darkness when stars are visible

@c4mer0n @TaylorWAnderson @Pflax1 Exactly

@ElectrekCo @FredericLambert This is complete nonsense

@TechVelocirap @M_xalher @Tesla @ValueAnalyst1 Exactly. A car being electric & upgradable to full self-driving maximizes future resale value.

@marialauraadr It’s not my finest work 🤣

@M_xalher @Tesla @ValueAnalyst1 Given how many countries are limiting or setting an end date for combustion engine cars, their future resale value cars will be low. Consumers are starting to realize this.

@MarcusHouseGame @SpaceX 👍

@SpaceX Krypton thrusters operative, satellites initiating orbit raise every 90 mins
