Video: Falcon 9 fires up engines for static fire test (members only)

Watch as the launch of a Falcon 9 rocket on a space station resupply run is aborted 13 seconds before liftoff when ground controllers were alerted to a potential problem with the vehicle’s second stage steering system.

SpaceX is preparing for liftoff Tuesday of its first mission for the U.S. Space Force, a launch from Cape Canaveral that will deploy a new GPS navigation satellite using a redesigned profile to allow the Falcon 9 rocket’s first stage booster to reserve enough propellant for landing on SpaceX’s drone ship in the Atlantic Ocean.

Powering into a pre-sunrise sky over Florida’s Space Coast on Friday, a SpaceX Falcon 9 rocket provided a memorable show as it climbed into sunlight, delivering a Dragon cargo craft to orbit on a trip to the International Space Station.
