Expedition Three Mikhail Tyurin gets ready to climb into a jet for a training flight with STS-105 Commander Scott Horowitz.

Expedition Three crew member Mikhail Tyurin, with the Russian Aviation and Space Agency, gets ready to climb into a T-38 jet for a training flight with STS-105 Commander Scott Horowitz. The two crews, STS-105 and Expedition Three, are at Kennedy to make final preparations for launch. On mission STS-105, Discovery will be transporting the Expedition Three crew and several payloads and scientific experiments to the International Space Station. The Early Ammonia Servicer (EAS) tank, which 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. Launch is scheduled for Aug. 9, 2001
