SpaceX and NASA have announced that the propulsion system designed to safely abort the upcoming crewed Dragon capsule, called SuperDraco, has been successfully fired 27 times and completed development testing. SuperDraco is a 3D-printed engine that’s designed to be throttled from 20 percent to 100 percent of thrust and can be restarted multiple times. The SuperDraco engines are going to be used to ensure that a crew capsule can abort a mission safely and land or splashdown.

The SuperDraco thrusters are scaled up versions of the small Draco thruster used for maneuvering and docking control on the upper stages of the Falcon 9 rocket, the upcoming Falcon Heavy, and the Dragon spacecraft. SuperDraco provides roughly 200 times more thrust than its little brother and is designed for a variety of use-cases and capabilities.
