Shuttle Columbia Rolls out to the Launch Pad
The space shuttle Columbia rolled out to the launch pad on Monday to prepare for the launch of STS-109; the fourth mission to retrieve and upgrade the Hubble Space Telescope. If everything goes smoothly, Columbia will lift off on February 28th, and rendezvous with the telescope in space. Over the course of the mission, shuttle astronauts will perform five spacewalks to install a new camera system, solar arrays, and power controller onto the aging space observatory.
