SpaceX’s streams typically kick off about 15 minutes before liftoff.
The last time this many crafts launched in a single weekend was when a Titan 4 rocket, a Delta 2 launcher and a NASA Space Shuttle all took off from different pads.
General Doug Schiess, commander of the 45th Space Wing, said this is a ‘historic week’ for the spaceport.
The Delta IV Heavy is the largest launcher in United Launch Alliance’s (ULA) fleet, consisting of three rocket cores strapped together.
