All eyes will be on UAE national Hazzaa Al Mansoori as he takes off with two other astronauts to the International Space Station (ISS) later today.
It will make him the first Emirati in space and the first Arab on the giant floating laboratory.
While addressing the media from the Baikonur Cosmodrome in Kazakhstan on Tuesday night, Al Mansoori said he had been overwhelmed by messages of support.
He also spoke of his immense pride in representing the Arab world.
Al Mansoori will lift-off at 5:56 pm UAE time today.
