Today, SpaceX completed a series of static fire engine tests of the Crew Dragon spacecraft in advance of an in-flight launch escape demonstration, known as the In-Flight Abort Test.

The engine tests, conducted near SpaceX’s Landing Zone 1 on Cape Canaveral Air Force Station in Florida, began with two burns for a duration of one-second each for two of Crew Dragon’s 16 Draco thrusters. The Draco thrusters are used for on-orbit maneuvering and attitude control, and would also be used for re-orientation during certain in-flight launch escapes. Following these initial Draco thruster burns, the team completed a full-duration firing for approximately nine seconds of Crew Dragon’s eight SuperDraco engines. The SuperDraco engines are designed to accelerate Dragon away from the F9 launch vehicle in the event of an emergency after liftoff.
