SpaceX's next generation Raptor engine roared into action at its test site in McGregor, Texas, in a video CEO Elon Musk posted on Twitter Sunday night.
This particular iteration of SpaceX's Raptor engine will be used to launch the space company's gigantic stainless steel Starship into space — and eventually to the Moon and beyond.
The new engine design will be responsible for getting the Starship spacecraft off the launch pad and boost it through the vacuum space. That's a surprising departure: so far, conventional rocket designs have used multiple stages, jettisoning fuel tanks and boosters as they ascend.
There will also be two versions of the Raptor engine: one specialized for sea level and one for vacuum optimized thrust. A total of seven Raptor engines will blast off in unison to launch the final Starship design.
Last week Musk tweeted some photos of the engine, adding that the company's new goal is to "reach the moon as fast as possible."
