Nasa and SpaceX are set to stream live the historical event of astronauts launching from the Kennedy Space Station.
It is the first time that astronauts have been set off from US soil since the Space Shuttle programme ended in 2011, and if SpaceX is successful it will mark the first time a private company has put humans into space.
Nasa will be streaming all of the events through its YouTube channel, which is known as Nasa TV.
Most more modern smart TVs should be able to load up the channel through built-in YouTube apps. Some platforms – from the Apple TV to the Amazon Fire TV – also have Nasa apps, where the same stream can be accessed.
The YouTube video can be found through the Nasa YouTube channel, or here:
The launch will happen at 8.22pm in the UK and around 9:22pm in South Africa.
Nasa’s coverage will begin a few hours before around 5pm in South Africa.
It is expected to keep going in some form until Sunday afternoon UK time, when the astronauts will arrive at the International Space Station and the first part of the mission will come to a close.
SpaceX will also be streaming the launch live on its YouTube channel, if you would prefer to visit there. At the previous launch, the coverage was split between the two organisations, so the two streams are unlikely to be different.
