In just over an hour's time, two US astronauts will be sent into space, aboard the Crew Dragon capsule.
It's a launch of particular consequence - the first to happen off of US soil since 2011, and the first done aboard a spacecraft built by the billionaire entrepreneur, Elon Musk's company, SpaceX.
While it's just a demonstration mission - to show SpaceX's ability to ferry astronauts to the International Space Station and back safely - it's being hotly anticipated across the world.
Brendan Byrne, the Space Reporter for the local radio station WMFE Orlando speaks to Susie Ferguson.
