After a delay caused by a glitch in one of their moving devices, NASA has finally sent the space shuttle Atlantis on its way to the launch pad at Kennedy Space Center in Florida.
Moving the space shuttle is a ponderous task. It requires a large moving device called a "crawler," which is capable of transporting 17 million pounds, but at a speed of less than 1 mile per hour.
Scientists are hoping that the glitch will not delay the launch of the shuttle, which is scheduled for no earlier than January 19th. It will carry the primary scientific laboratory module to the International Space Station.
