A test fire of SpaceX’s newest engine reached the power level necessary for the company’s next round of rocket designs, CEO Elon Musk said on Twitter.
“Raptor just achieved power level needed for Starship & Super Heavy,” he tweeted on Feb. 7, four days after he shared a photograph of the first test of a flight-ready engine.
The Raptor engine is designed to power the spaceship currently known as Starship as part of the rocket assembly currently known as Super Heavy (previously dubbed the BFR). The first Raptor test fire took place in September 2016, when the company was targeting an uncrewed Mars launch in 2018.
