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.
