The Tesla Roadster is supposed to be sent into a virtually indefinite solar orbit, on a path taking it as far from Earth as Mars. Adding to the whimsy, SpaceX has planted a space-suited mannequin in the driver's seat of the convertible.

Whether the car makes it onto its planned trajectory will not be known before late on Tuesday, SpaceX said. The roadster, which carries a plaque inscribed with the names of more than 6,000 SpaceX employees, could instead end up in Earth orbit.

The launch followed an impressive run of successful paid missions - 20 in all since January 2017, when SpaceX returned to flight following a 2016 launchpad accident that destroyed a $62 million rocket and a $200 million Israeli communications satellite that it was to put into orbit two days later.

SpaceX had previously announced plans to eventually use the Falcon Heavy to launch two paying space tourists on a trip around the moon and back. Musk said on Monday he was now inclined to reserve that mission for development of an even more powerful SpaceX launch system, the Big Falcon Rocket, or BFR, which he said was proceeding more quickly than expected.
