4K Video: The launch of Crew 4 as seen from the press site

A Falcon 9 rocket powered by a reused first stage booster rolled out Tuesday to pad 39A at NASA’s Kennedy Space Center in Florida, a day before its scheduled liftoff with an Airbus-built communications satellite designed for television broadcasts over the Americas.

The EchoStar 23 communications satellite, on the way to a 15-year service life broadcasting television signals, launched aboard a SpaceX Falcon 9 rocket Thursday from pad 39A at NASA’s Kennedy Space Center in Florida.

SpaceX rolled a fully-assembled Falcon 9 booster out of its hangar and lifted it on top of a launch pad Friday for the first time since an explosion grounded the commercial rocket last year, setting the stage for a one-second launch window Saturday to take off from California’s Central Coast and deploy the first 10 satellites in orbit for a $3 billion upgrade to Iridium’s globe-spanning message relay network.
