Watch SpaceX's New Falcon Heavy, Tesla Roadster, Starman Video

The world's most powerful rocket SpaceX's Falcon Heavy blasted off in February on its maiden test flight from Cape Canaveral Florida. AFP

Eccentric billionaire and SpaceX founder Elon Musk broke the news during his appearance at the South By Southwest festival this past weekend (he appears to be a big fan of Westworld), claiming that the SpaceX Mars rocket is making steady progress, and will very likely be making short test flights starting next year.

Dubbed as "Falcon Heavy and Starman", the videos show the preparation, success, and failures of the Falcon Heavy launch last month.

"There are a lot of negative things in the world - a lot of bad things happening all the time, lots of problems that need to get solved - but life can not just be about solving one miserable problem after another".

Nolan, in comments reported by The Verge, said he produced the video in part to inspire the public in the way he was inspired by Saturn rocket launches.

The payload was Elon Musk's personal Tesla Roadster, which is now in orbit in outer space.

Nolan, who was at ground control with Musk during the SpaceX launch, wanted to express how he felt "the only way he knew how", and ended the panel with three-minutes of footage that was captured that day.

To help generate that kind of excitement, the video uses music from David Bowie - though it's not "Starman", the song that SpaceX named the Roadster's spacesuited driver after. "We tried to distill that essence down". Life can't be about "solving one miserable thing after another", he said.

The Westworld co-creator clarified that the video was not a trailer for a forthcoming movie or TV show, but simply "we're hoping this is the trailer for one part of the next chapter of the human story". They have to be things that "make you glad to wake up in the morning", and concepts like electric cars and space travel certainly qualify.
