The Crew Dragon’s launch escape system (LES), consisting of a set of eight SuperDraco engines integrated into the spacecraft’s body, has been armed in preparation for launch. The LES is designed to separate the spacecraft from the Falcon 9 rocket and carry the crew away to safety in the unlikely event of an emergency.
The system was tested during January’s uncrewed In-Flight Abort Test to show the Crew Dragon’s capability to safely separate from the Falcon 9 rocket. For that test, SpaceX configured Crew Dragon to trigger a launch escape about a minute and a half after liftoff. All major functions were performed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down just off the Florida coast in the Atlantic Ocean.
