Stephen Colbert has always had a passion for space exploration. His most recent PSA posted on the NASA website, urges his followers in the Colbert Nation to support NASA's work on the International Space Station to develop alterate vaccines to diseases which have been developing resistance to traditional antibiotics.
Colbert is no stranger to space technology. In 2009 he entered a competion to name a new node of the ISS. Colbert won after encouraging his fans to vote for the node to be named "Colbert." Although he technically won the competition, NASA untimatley decided not to name it after the pundit, and christened the new node "Tranquility" instead. As a conslation prize, NASA named a new piece of excerise equipoment on the ISS as the C.O.L.B.E.R.T. treadmill. The acronym stands for Combined Operational Load-bearing External Resistance Treadmill.
Beyond the ISS node naming incident, back in 2008 Colbert ventured to save humanity by having his DNA sent into orbit. A digitized version of Colbert's genetic code was sent to the ISS with space-tourist and video game designer Richard Garriott. Colbert referred to this as an "Immortality Drive." Garriott acknowledged that the preservation of Colbert's DNA would allow aliens to one day clone him and save humanity, "is there a better person for us to turn to for this high-level responsibility?"
