"I am thrilled to have my DNA shot into space, as this brings me one step closer to my lifelong dream of being the baby at the end of 2001," Colbert said in a statement, referring to the 1968 landmark science fiction film "2001: A Space Odyssey."
Garriott, one of few private citizens to travel into space, is collecting material for a time capsule of human DNA, a history of humanity's greatest achievements and personal messages.
