The Expedition Three and STS-105 crews are preparing for launch on Aug. 9. On mission STS-105, Discovery will be transporting the Expedition Three crew and several payloads and scientific experiments to the Space Station. The Early Ammonia Servicer (EAS) tank, which contains spare ammonia for the Station’s cooling system and will support the thermal control subsystems until a permanent system is activated, will be attached to the Station during two spacewalks. The three-member Expedition Two crew will be returning to Earth aboard Discovery after a five-month stay on the Station
