CAPE CANAVERAL, Fla. – This decal will be placed on the Combined Operational Load Bearing External Resistance Treadmill, or C.O.L.B.E.R.T., that will be carried to the International Space Station aboard space shuttle Discovery on the STS-128 mission. The treadmill is in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida and will be placed in the Leonardo multi-purpose logistics module with science and storage racks. The treadmill is named after comedian Stephen Colbert, the host of Comedy Central’s “The Colbert Report.” Colbert urged his viewers to suggest the name “Colbert” as the name for the station’s Node 3 module. Although his name did receive the most entries in an Internet polling contest, NASA chose the name “Tranquility” to honor the accomplishments of the Apollo 11 mission. COLBERT will be installed in Tranquility after the node arrives at the station next year. Launch of STS-128 is targeted for Aug. 7, 2009. Photo credit: NASA/Jim Grossmann

S85-37165 (8-12 July 1985) -- Sharon C. (Christa) McAuliffe of Concord High, Concord, New Hampshire, runs in place on treadmill to test physiological responses at Johnson Space Center. Christa McAuliffe was eventually chosen as the first Teacher in Space and was a member of the seven-member Challenger shuttle crew which died tragically in the explosion of the spacecraft during the launch of STS-51L from the Kennedy Space Center about 11:40 a.m., EST, on Jan. 28, 1986. The explosion occurred 73 seconds into the flight as a result of a leak in one of two Solid Rocket Boosters that ignited the main liquid fuel tank. The crew members of the Challenger represented a cross-section of the American population in terms of race, gender, geography, background, and religion. The explosion became one of the most significant events of the 1980s, as billions around the world saw the accident on television and empathized with any one of the several crew members killed.
