Watch SpaceX launch its Falcon Heavy rocket live right here


After 7 years in development, SpaceX is about to launch its Falcon Heavy rocket, a ship that could someday carry missions to Jupiter or Saturn. If successful, the rocket would be the most powerful in operation in the world.

Also, riding along for today's test flight is SpaceX founder Elon Musk’s Tesla Roadster to prove that his rocket can carry heavy payloads to far off places like the surface of Mars, and also to brag that he has a car in space.
