The Space Shuttle Atlantis made the four-hour journey to its launch pad today, demonstrating that the shuttle fleet is ready to fly again. Atlantis and the rest of the fleet were grounded for the last few months so that technicians could weld tiny cracks that had formed along the shuttle’s fuel lines. NASA also had to repair cracked bearings on the 37-year old transporter. Atlantis may launch as soon as October 2nd.
