Before dawn, the payload canister with the Multi-Purpose Logistics Module Leonardo inside arrives at Launch Pad 39B. The canister will be raised to the payload changeout room above (on the Rotating Service Structure) for transfer into Space Shuttle Discovery’s payload bay. Leonardo, one of Italy’s major contributions to the International Space Station program, is a reusable logistics carrier. It is the primary delivery system used to resupply and return Station cargo requiring a pressurized environment. Leonardo is the primary payload on mission STS-102 and will deliver up to 10 tons of laboratory racks filled with equipment, experiments and supplies for outfitting the newly installed U.S. Laboratory Destiny. STS-102 is scheduled to launch March 8 at 6:45 a.m. EST
