Instead of the boilerplate mass simulators flown on test flights of past rockets, SpaceX founder and CEO Elon Musk picked a more colorful payload for Falcon Heavy’s maiden voyage: a cherry-red Tesla Roadster from one of his other entrepreneurial ventures.

SpaceX rolled the company’s Falcon Heavy rocket up the ramp to Launch Complex 39A at Florida’s Kennedy Space Center for the first time on December 28, 2017 for a critical series of fit checks to confirm the tri-core rocket is compatible with its launch pad.
