Hearing that NASA and SpaceX are now targeting no earlier than Jan. 18 for Crew Dragon's Inflight Abort Test. Falcon 9 static fire set for as early as the end of this week.

Dome to barrel weld made it to 7.1 bar, which is pretty good as ~6 bar is needed for orbital flight. With more precise parts & better welding conditions, we should reach ~8.5 bar, which is the 1.4 factor of safety needed for crewed flight.

6 bar is flight pressure?! That’s like double F9 right? So really the Starship has even more prop than I realized 🤯 that thing is a beast!

A given tank pressure is needed to feed the engine turbopumps & pressure-stabilize/relieve compression load on the cylinder walls
Buff Mage @elonmusk·4 ч
Everything is compressible, but liquid compression at these pressures is not significant. However, the tanks do expand under pressure, creating a bit more volume. Keeping propellant super cold has a big effect on density of ~10% in case of CH4.

Will Starship SN1 use the same thickness of stainless steel as this pathfinder tank?
Buff Mage @elonmusk·1 ч
Yes
