The launch of the missile was planned from 2013 and was canceled several times. The last time it was postponed in the summer of 2017 – SpaceX was informed that it takes them two to three months to deliver the Falcon Heavy accelerators to Cape Canaveral, where the John F. Kennedy Space Center is located.
Falcon Heavy, a rocket of the super-heavy Falcon family, has three Falcon 9 accelerators, which will reduce the load on the launch vehicle by three times.
The developers planned to use the Falcon Heavy starting stages again, but, according to Ilona Mask, this is unlikely to be done the first time.
The rocket starts from the NASA 39A site at the Kennedy Space Center, but the exact date and time of launch are not yet determined.
