Turns out Elon Musk wasn't kidding.
The Falcon Heavy is the largest rocket launched into space since the NASA Saturn V in the early 1970s.
It is common for rockets to carry a dummy payload during test flights. Musk and company decided to load the rocket with an original Tesla Roadster with a SpaceX suit-wearing dummy in the driver's seat.
SpaceX successfully landed all three boosters that propelled the rocket, but the rocket's second stage, with the Roadster on top, was launched into an orbit around the sun.
