Falcon Heavy proved computer software for designing Big Falcon Rocket

The SpaceX Big Falcon Rocket is undergoing detailed engineering design now. It is being designed with the same computer model designs and software that were used for the successful Falcon Heavy.

The successful first test of the SpaceX Falcon Heavy gives Elon Musk confidence in the computer design models.

In 2019, we should be seeing short hop testing of the Big Falcon Rocket and Big Falcon Ship.

In 2012 and 2013, there were many tests of the SpaceX grasshopper spaceship.

In 2020-2021, Elon is projecting a first orbital flight for the Big Falcon Rocket.

Elon Musk said that a fully fueled Big Falcon Rocket could fly to orbit in a single stage.
