SpaceX’s StarshipSuper Heavy rocket test-fires 7 engines (video)

SpaceX fired seven engines on its Starship Super Heavy prototype “Booster 7” on Monday (Sept. 19), marking the highest number of the company’s new Raptor engines ever tested at the same time.

The company is testing some of Booster 7’s engines ahead of its planned first orbital flight of Starship, a 165-foot tall (50 meters) reusable spacecraft that will be lifted to orbit by 33 next-generation Raptor engines inside a Super Heavy booster, which stands 230 feet (70 m) tall. Starship will feature six of the engines.
