SpaceX SN4 Starship Prototype Passed Cryo Fuel Test

The SpaceX SN4 Starship has passed a lower pressure cryo fuel test. The next milestone will be the static fire test, where the Starship will be held in place during engine firing.

SN4 will have one engine and a lower pressure 200-meter flight.
SpaceX is already assembling Starship SN5.

Newer Starships will switch to a new steel alloy that has higher strength under cryo temperatures. The new material will be able to handle higher pressures for higher altitude and orbital flights.
