SpaceX's Falcon Heavy rocket could launch again

The first flight of the Falcon Heavy and its three powerful rockets was a space highlight of 2018. While that test flight's payload was a red Tesla sports car with a spacesuited mannequin in its driver's seat\, the payload this time will be a communications satellite for a Saudi Arabia-based organization called Arabsat.
