The cherry red Tesla Roadster on its way into deep space is a tremendous success for Elon Musk, the billionaire behind the SpaceX rocket launch and electric cars. “It’s kind of silly and fun,” he said Tuesday at a press conference after the launch. “But silly and fun things are important. Normally for a new rocket, they’d launch like a block of concrete or something. That’s so boring.” Musk launched the car on board the rocket as it played David Bowie songs on loop.
