SN8 Static Fire:
Sunday night’s test follows an aborted attempt earlier in the week.

Although SpaceX has conducted numerous Static Fire tests with its Starship prototypes, this is the first time three Raptors will have been fired together. This includes at SpaceX’s test center in McGregor, Texas – where Raptors are test fired individually.
The test path has been refined over the evolution of Starship, with two objectives within a few hours of each other set to take place.
Once the vehicle has been prop-loaded, controllers will conduct a preburner test. A preburner is essentially a small engine that powers a turbopump. Each Raptor engine has two, one for the liquid oxygen oxidizer and one for the methane fuel.
