(02/12/2001) -- Space Shuttle Discovery begins rolling into the fog that shrouds Kennedy Space Center. Discovery is on its way from the Vehicle Assembly Building to Launch Pad 39B and 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
