SpaceX is inching closer to being ready to launch its next-generation rocket on its first demonstration flight to space after another successful static firing for Starship's Super Heavy booster. 

On Monday, the team at the Starbase development center in Texas lit up a Super Heavy loaded with seven Raptor engines for the first time. That's more than double the previous record, when SpaceX unleashed the fire under three Raptors just three weeks ago. 

A static fire test is the rough equivalent of revving a car engine in neutral. The booster is held to the ground while the engines are fired. On Monday, the prototype dubbed Booster 7 successfully fired its seven engines for about 10 seconds.
