Watch the Falcon 9 and Crew Dragon arrive at the launch pad (members only)

The Falcon Heavy rocket was lowered to the horizontal position before sunrise Friday morning after less than a day standing at the launch pad.

Six days after SpaceX fired its last Falcon 9 rocket from NASA’s Kennedy Space Center, another launcher rolled to historic pad 39A and ignited its nine Merlin 1D engines at sunset Thursday in preparation for a commercial satellite delivery mission Sunday for Intelsat.

Taking delivery of the Atlas 5 rocket that will boost an advanced weather observatory into space next month, United Launch Alliance and the Air Force are back at work following disruptions from Hurricane Matthew.
