The Falcon 9 rocket’s main engines briefly ignited at launch pad 39A in a standard pre-launch test. This is the second time this booster has test fired its engines on a launch pad at Cape Canaveral. The first stage first fired at launch complex 40 prior to the CRS-8 space station resupply mission in April last year. It is scheduled to be the first SpaceX rocket to launch a second time when it carries the SES 10 communications satellite into orbit later this week.

Live coverage: SpaceX successfully performs Crew Dragon abort test
SpaceX launched an unpiloted Crew Dragon spacecraft aboard a Falcon 9 rocket from pad 39A at the Kennedy Space Center at 10:30 a.m. EST (1530 GMT) Sunday. SpaceX triggered an escape maneuver using the Dragon’s thrusters about a minute-and-a-half after liftoff to verify the launch abort engines can safely carry the capsule — and astronauts on future missions — away from a failing rocket.
