SpaceX biggest project is the StarShip, consisting of a Ship, and a Booster - the largest, strongest, and most economic Rocket ever built.
The Booster7 in this case, has 33 Raptor2 engines, which were tested in unison on February 9th 2023.
Correction: 33 were planned, one was deactivated, one decided not to fire on its own.
Summary: 31 Raptor2 eniges fired, 29 would be necessary to reach orbit.
There is ONE word for it: Redundancy.
Congratulations to SpaceX!
