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 cargo this time will be a communications satellite for a Saudi Arabia-based organization called Arabsat. The launch was postponed from April 10th to April 11th because of weather conditions. Follow the launch here: https://nyti.ms/2WYtKiw
