The world's first privately built spacecraft is expected to be visible over Irish skies at around 950pm tonight.
The SpaceX rocket is the first manned launch from US soil since 2011 and the mission, known as Demo-2, will allow the US to once again send humans into space.
Robert Behnken and Douglas Hurley will travel to the International Space Station (ISS) in the spacecraft built by billionaire entrepreneur Elon Musk's company.

Astronaut Tim Peake said the rocket will also be visible in you look south-west.
