Astronaut Sunita L. Williams, appearing on "The Colbert Report" on cable TV network Comedy Central, said NASA will name the new module Tranquility, instead of Colbert as he and his fans demanded after winning an online poll conducted by NASA.
But the U.S. space agency did make one concession. It said it will make a new Combined Operational Load-Bearing External Resistance Treadmill (COLBERT) -- a fancy way of saying "exercise treadmill" -- a key fixture in the space station.
"Your name will be in space in a very important place," Williams assured Colbert on his TV show. "Everyday somebody will have to jump on the COLBERT," she said.
