The engines, known as SuperDracos, are part of the Crew Dragon’s emergency abort system, which will definitely come in handy if anything goes wrong during a future trip to space. The engines are designed to ignite if the rocket carrying the Crew Dragon starts to malfunction. The thrusters will then carry the Crew Dragon to safety, prompting the capsule’s parachutes to deploy and gently lower the capsule into the ocean.
The date for the in-flight abort hasn’t been released yet, so it may still be some time before the Crew Dragon flies again. For now, you can watch the SuperDracos in action with this latest video and imagine them firing midflight.
