Eight SuperDraco engines boost a SpaceX Crew Dragon spacecraft away from Space Launch Complex 40 at Cape Canaveral Air Force Station in an emergency pad abort simulation. Each of the eight SuperDraco engine generates 15,000 pounds of thrust and burns about six seconds. The test began at 9 a.m. After the engines shut down, the Dragon spacecraft's trunk, with passive fins for stability, will separate when it reaches peak altitude.
