SpaceX successfully completed a "static fire test" of the "world's most powerful" rocket back in May.
The SpaceX frontman revealed his audacious plans via Twitter late Friday, saying that the first payload for his company's brand spanking new Falcon Heavy Rocket, which is due to launch next month, will be his very own "midnight cherry Tesla Roadster".
"She will remain in space for billions of years, if not explode at the start", said Musk.
In the meantime, the Falcon Heavy is meant to boost the amount of cargo SpaceX can take into space for its customers. It will have its maiden voyage somewhere at the beginning of 2018 (current launch date is set somewhere in January), and people wondered what it could use as a payload. Currently, Falcon 9 can bring just over 50,000lb to lower Earth orbit.
The rocket will be capable of lifting more than 54 metric tons, which is equal to a 737 jetliner full of fuel, luggage, crew, and passengers. Musk is hopeful it actually makes it up into the air, partly because his vehicle may (or may not) be part of the Falcon Heavy's initial cargo.
SpaceX wants to send their first cargo mission to the red planet in 2022. Musk said at a press conference earlier this year that Heavy might not even make it to orbit the first time it leaves the atmosphere. Its objectives will be to identify hazards and confirm water resources while putting an initial life support, mining, and power infrastructure in place. The spacecraft from these initial missions will also serve as the beginnings of SpaceX's first Mars base where they will build a thriving city and gradually a self-sustaining civilization on the planet.
