The STS-105 and Expedition Three crews give thumbs up on another opportunity to launch after a 24-hour weather delay. In red shirts, seated left to right, are STS-105 Mission Specialists Patrick Forrester and Daniel Barry, Pilot Rick Sturckow and Commander Scott Horowitz. In blue shirts are the Expedition Three crew, Commander Frank Culbertson, Vladimir Dezhurov and Mikhail Tyurin. Dezhurov and Tyurin are cosmonauts with the Russian Aviation and Space Agency. Highlighting the mission will be the rotation of the International Space Station crew, the third flight of an Italian-built Multi-Purpose Logistics Module delivering additional scientific racks, equipment and supplies for the Space Station, and two spacewalks. Included in the payload is the Early Ammonia Servicer (EAS) tank, which will be attached to the Station during the spacewalks. The EAS will be installed on the P6 truss, which holds the Station’s giant U.S. solar arrays, batteries and the cooling radiators. The EAS 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. Launch is scheduled for 5:15 p.m. EDT Aug. 10
