KENNEDY SPACE CENTER, Fla. -- The solid rocket booster on Space Shuttle Discovery expends a column of flame as it hurtles into the sky on mission STS-105 to the International Space Station. Liftoff from Launch Pad 39A occurred at 5:10:14 p.m. EDT. Besides the Shuttle crew of four, Discovery carries the Expedition Three crew who will replace Expedition Two on the Space Station. The mission includes the third flight of an Italian-built Multi-Purpose Logistics Module delivering additional scientific racks, equipment and supplies for the Space Station and the Early Ammonia Servicer (EAS) tank. The EAS, which will be attached to the Station during two spacewalks, contains spare ammonia for the Station’s cooling system. The three-member Expedition Two crew will be returning to Earth aboard Discovery after a five-month stay on the Station
