Geldof says, "Being the first Irishman in space is not only a fantastic honor but pretty mind-blowing. The first rock astronaut space rat! Elvis may have left the building, but Bob Geldof will have left the planet! Wild! Who would have thought it possible in my lifetime."
Geldof, 61, will begin training for the mission in a flight simulator in the Netherlands this weekend (14-15Sep13).
The SXC flight was launched as a rival to Sir Richard Branson's Virgin Galactic project, which has already attracted stars including Justin Bieber, Ashton Kutcher and Leonardo DiCaprio.
