The time has finally come for SpaceX to launch its Falcon Heavy rocket from Kennedy Space Center

What is SpaceX Falcon Heavy?

The vehicle consists of three Falcon 9 cores strapped together, giving the rocket an awesome amount of power. And since each Falcon 9 has nine main rocket engines, there are 27 total engines that will all be used to send this vehicle to space.

All of this hardware creates more than 5 million pounds of thrust at liftoff. That makes the Falcon Heavy capable of putting around 140,000 pounds of cargo into lower Earth orbit, earning the title of the most powerful rocket in the world.

When are they launching it and how to watch?

SpaceX will broadcast the launch on its website, spacex.com, beginning at 11:40 p.m today and on YouTube.
