On 14 April 2009, astronaut Sunita Williams appeared on "The Colbert Report", and announced the name of the node would be "Tranquility". The name was chosen in honor of the 40th Anniversary of the first lunar landing of Apollo 11 on the Sea of Tranquility. However, the treadmill the astronauts use for exercise has been named "C.O.L.B.E.R.T." for "Combined Operational Load Bearing External Resistance Treadmill" and is located in "Tranquility". Colbert was thrilled and happily accepted this offer. The treadmill traveled to space aboard Space Shuttle mission STS-128 on 28 August 2009, for eventual installation in the "Tranquility" node during STS-130.
