Nasa SpaceX launch live: Stream, time, weather how to watch and latest video as astronauts sent into space
Nasa and SpaceX are about to launch two astronauts into orbit and make history.
It will be the first time a private company has put humans into space, and the first time that Nasa has sent its astronauts into orbit from US soil since the end of the Space Shuttle programme in 2011.
The launch begins at 4.33pm local time, or 9.33pm in the UK.
It can be viewed in the live stream below – and there may even be the opportunity to spot the launch from the ground.
