Space Shuttle Discovery moves up the ramp to the top of Launch Pad 39B. The early morning fog that had cleared for the rollout from the Vehicle Assembly Building can be seen rolling back over the pad. Discovery will be flying on mission STS-102 to the International Space Station. Its payload is the Multi-Purpose Logistics Module Leonardo, a “moving van,” to carry laboratory racks filled with equipment, experiments and supplies to and from the Space Station aboard the Space Shuttle. The flight will also carry the Expedition Two crew up to the Space Station, replacing Expedition One, who will return to Earth on Discovery. Launch is scheduled for March 8 at 6:45 a.m. EST
