@WorldAndScience Yes! People are almost always surprised to learn that Earth’s gravitational reach is infinite. “Zero gravity” is achieved by zooming around Earth super fast until outward acceleration equals inward acceleration of gravity.

@Robotbeat @Jon128123 @Diver2441 @Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @alan1bernard Our superalloy foundry is now almost fully operational. This allows rapid iteration on Raptor.

@Robotbeat @Jon128123 @Diver2441 @Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @alan1bernard SpaceX metallurgy team developed SX500 superalloy for 12000 psi, hot oxygen-rich gas. It was hard. Almost any metal turns into a flare in those conditions.

@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard You def don’t want electric pumps on a rocket engine! Raptor turbopumps alone need 100,000 horsepower per engine. That’s not a typo.

@Erdayastronaut @NASASpaceflight @_Synders @John_Gardi @martinengwicht @JeromeJaccard @Robotbeat @alan1bernard Yes, full flow, gas-gas, staged combustion. Will take us time to work up to 300 bar. That is a mad level.

@Erdayastronaut @ludan27 @JeromeJaccard @Robotbeat @alan1bernard Seriously! We are just on the wrong planet for SSTO. Mars, no problem.
