"We are building the first ship, the first interplanetary ship right now, and I think we will be able to do short flights, short sort of up and down flights, probably sometime in the first half of next year", explained Musk.
However, he admitted this deadline may be a little optimistic, adding: 'Although sometimes, my timelines are a little, you know'.
The billionaire also detailed how society would function on a Mars colony.
He fears another "dark age" should a third world war occur, and feels that Mars will be integral to helping the human race survive and regenerate.
More pressing to Mr Musk, and the investors that enable him, might be the backlog of orders for the Model 3, Tesla's "affordable" new auto.
Mr Musk also got divorced, and he said he had to borrow money from his friends to pay his rent.
The rocket's primary payload, a 3,200-pound radar-imaging satellite called PAZ, for the Spanish government, and SpaceX's newly dubbed Tintin A & Tintin B satellites (formally known as Microsat-2a and Microsat-2b) were successfully deployed about 11 minutes after the Falcon lifted off.
"What's fantastic about the ship, assuming we can make full and rapid reusability work is that we can reduce the cost, marginal cost per flight, dramatically, by orders of magnitude compared to where it is today", Musk said. After that, "then really the explosion of entrepreneurial opportunity [will begin] because Mars will need everything from iron foundries to pizza joints". In the long-term, the billionaire space entrepreneur whose plans include making human life multi-planetary, intends to make Starlink a communication bridge between Earth and colonized Mars.
The short film may have been a different angle for the Westworld team, but they showcased their ability to create an eclectic film portraying the time, effort and process of the Falcon Heavy launch as if we were involved ourselves - and let's face it, we wish we were.
"Mark my words: AI is far more unsafe than nukes, by far, so why do we have no regulatory oversight, this is insane".
"The biggest thing that would be helpful is just general support and encouragement and goodwill", Musk said. And if he doesn't try and get us to Mars, who will?
