Colbert's DNA is going to the ISS as part of a time capsule of human DNA and other items.
"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 the unlikely event that Earth and humanity are destroyed, mankind can be resurrected with Stephen Colbert's DNA," Garriott said in a statement. "Is there a better person for us to turn to for this high-level responsibility?"
Indeed, who better? :D
