SpaceX Starship SN4
SN4 passed its cryo test last night. They kicked it up to 4.9 bar which is about 56psi. That's enough for engine tests, but I believe they want to eventually hit 8.4 bar. Before long the SN4 will have a Raptor engine and may have a static test by the end of the week. They plan to slap on some heat tiles to test installation procedures and see how they handle stresses during the static tests and eventual short hops. Whether this ever becomes successful or not, it's still really cool how fast and how far they have come compared to the embarrassing sloth called the SLS.

While I still gotta say this thing looks like something out of a Wallace and Gromit movie (and I liked those movies), I'm still very curious to see this thing go and be a success.

I looked at the previous 3 failures. They looked like implosions.
Do you think they might have been caused by the air in the tank cooling and contracting? |

By the way, today I ordered body tubes and a nose cone to model the Starship.
I wanted to model the stack but the superheavy has relitively little fin area. |

Quote:
I think I read that two of the three were tested to failure, and the failure point was welded seams. The third one supposedly was due to a mistake in procedure.

Just realized
Maybe they’re vented until they’re full to prevent that? IDK |

Space-X successfully tested the SN4 yesterday, in a series of tests that concluded with a three second firing of the methane powered Raptor engine yesterday. Once the FAA clears them, they will hopefully make the first "hop" flight.
