They looked on as the nose cone housing the Tesla was stripped away, exposing the electric car to the vacuum of space as David Bowie's "Life on Mars" played, ushering it to orbit. Thousands continued watching a livestream of the Tesla and its passenger "Starman" as it flew past the Earth into deep space. SEE ALSO: The Tesla Roadster effectively looks like a star moving slowly across the sky. Astronomers still aren't exactly sure where the Tesla is heading. According to SpaceX founder Elon Musk, the Tesla overshot its initial orbit and is heading toward the asteroid belt, but that may not be the full story. The Tesla likely won't make it all the way to the asteroid belt, and according to astrophysicist Jonathan McDowell, the Roadster and Starman will make it beyond Mars, but not quite to the asteroid belt. But wherever it goes, the Tesla and Starman will likely be on their own in deep space for a very long time. Featured Video For You
